技术领域 FIELD

[0002] 本发明涉及一种可以减小液晶显示器中Y特性的视角依赖性的结构和/或驱动方法。 [0002] The present invention relates to a structure can be reduced and / or method of driving a liquid crystal display in the viewing angle dependence characteristic Y.

背景技术 Background technique

[0003] 液晶显示器是一种具有良好特性(包括高分辨率、较小的厚度、较轻的重量和较低的功耗)的平板显示器。 [0003] a liquid crystal display device having good characteristics (including high resolution, small thickness, light weight and low power consumption) of the flat panel display. 随着显示性能和产量的提高以及与其它类型显示器相比的价格优势,其市场份额也在迅速扩张。 With the display to improve the performance and yield and price advantage compared with other types of displays, its market share is rapidly expanding.

[0004] 通常常规使用的扭曲相列向(TN)液晶显示器具有正介电各向异性的液晶分子,液晶分子以其长轴取向近似平行于基底表面且沿液晶层的厚度方向扭转90°的方式分布在上下基底之间。 [0004] generally used in a conventional twisted nematic having a positive dielectric anisotropy of liquid crystal molecules (TN) liquid crystal display, the liquid crystal molecules with their long axis oriented parallel to the substrate surface of approximately 90 ° and the twist in the thickness direction of the liquid crystal layer distributed between the upper and lower substrates. 当对液晶层施加电压时,液晶分子开始平行于电场,释放扭转排列。 When a voltage is applied to the liquid crystal layer, the liquid crystal molecules parallel to the electric field starts, the release arrangement twist. TN液晶显示器利用电压造成的液晶分子的取向改变导致的旋转极化的改变来控制透光量。 Orientation of liquid crystal molecules in TN liquid crystal display with a voltage change caused by the rotation of the polarization change causes the amount of transmitted light is controlled.

[0005] TN液晶显示器允许有很宽的制造容限和高的产量。 [0005] TN liquid crystal display allows wide manufacturing tolerances and a high yield. 另一方面,它还有显示性能、尤其是视角特性的问题。 On the other hand, it also display performance, especially the problem of viewing angle characteristics. 具体地说,当斜视TN液晶显示器的显示表面时,显示对比度下降得相当厉害。 Specifically, when the display surface of the TN liquid crystal display of a perspective view, showing a decrease in contrast was very powerful. 因此,即使从正前方看时图象清晰地呈现出从黑到白多个灰度,但在斜视时灰度之间的亮度差也显得极不清晰。 Accordingly, even when viewed from the front of the image clearly presents a plurality of gray scale from black to white, but in the oblique luminance difference between gradation also appears extremely clear. 此外,还存在从正前方看时显暗的部分在斜视时显亮的现象。 Further, there is significant when viewed from the front of the dark portion when the highlighted perspective phenomenon.

[0006] 为了改善TN液晶显示器的视角特性,近来开发了一些液晶显示器,包括日本公开专利JP63-21907中描述的共面切换(IPS)型液晶显示器、日本待公开专利中描述的多畴垂直排列(MVA)型液晶显示器、日本待公开专利JP10-186330中描述的轴向对称微盒(ASM)型显示器,和日本待公开专利JP2002-55343中描述的液晶显示器。 [0006] In order to improve the viewing angle characteristics of TN liquid crystal display, recently developed a number of liquid crystal display, comprising coplanar Japanese Patent JP63-21907 described switching (IPS) type liquid crystal display, as described in Japanese Patent Publication multi-domain vertical alignment (MVA) liquid crystal display, Japanese Laid-Open Patent JP10-186330 axial described symmetrical micro cassette (ASM) type display, a liquid crystal display, and Japanese Patent Publication JP2002-55343 described.

[0007] 采用上述任一新颖模式(宽视角模式)的液晶显示器解决了视角特性的具体问题。 [0007] Using either a novel mode (wide viewing angle mode) liquid crystal display to solve the specific problems in viewing angle characteristics. 尤其是它们没有在斜视TN液晶显示器的显示表面时表现出的对比度或显示灰度显著下降的问题。 In particular they do not show a perspective view of the display surface of the TN liquid crystal display contrast or gradation display problems significantly decreased.

[0008] 在液晶显示器的显示质量得到改善的情况下,又面临视角特性的新问题,S卩Y特性的视角依赖性,这意味着从正前方观看显示器和斜视显示器时存在Y特性差异。 New Problems [0008] In the case where the display quality is improved, but also facing the viewing angle characteristics, S Y Jie viewing angle dependence characteristics, a difference in characteristics when Y is present which means the display is viewed from the front, and perspective display. 这样在显示图象(例如照片)或显示电视广播等时就出现问题。 So that the display image (e.g., photograph) or a problem arises when displaying television broadcasting.

[0009] Y特性的视角依赖性在MVA模式和ASM模式中比在IPS模式中更为突出。 [0009] Y viewing angle dependence characteristics in MVA mode and ASM mode is more prominent than in the IPS mode. 另一方面,比MVA或ASM板更难以高产量地制作从正前方看时具有较高对比度的IPS板。 On the other hand, more than MVA or ASM panels difficult to produce high yield of a higher contrast IPS plate when viewed from the front. 因而,希望减小MVA模式或ASM模式的Y特性的视角依赖性。 Accordingly, it is desirable to reduce the viewing angle dependence characteristics of the MVA mode or ASM mode Y.

[0010] 鉴于上述问题产生了本发明。 [0010] In view of the above-described problems of the present invention. 本发明的主要目的在于提供一种具有减小的Y特性视角依赖性的液晶显示器。 The main object of the present invention is to provide a liquid crystal display with reduced viewing angle dependence of characteristics of Y. 发明内容 SUMMARY

[0160] 首先参见图1、2A、2B和2C。 [0160] Referring first to FIG. 1,2A, 2B and 2C. 图1是表示根据本发明实施例的液晶显示器100的象素中电极分布的示意图。 FIG 1 is a diagram showing the distribution of the pixels of the liquid crystal display according to an embodiment of the present invention, the electrode 100. 图2A是液晶显示器100的总体结构示意图,图2B是象素中电极结构的示意图,图2C是图2B中沿2C-2C'的截面图。 2A is a schematic view of the overall configuration of the liquid crystal display 100, FIG. 2B is a schematic view of the structure of the pixel electrode, FIG. 2C in FIG. 2B is a sectional view along the 2C-2C 'of. 出于参考的目的,图3A、3B和3C分别表示常规液晶显示器100'的象素中电极分布、电极结构和沿3C-3C'的截面图。 For reference purposes, FIG. 3A, 3B and 3C respectively represent a sectional view of a conventional liquid crystal display 100 'of distribution electrodes, and the electrode structure along 3C-3C pixel apos.

[0161] 根据本实施例的液晶显示器100以常黑模式工作,并且包括大量象素,每个象素具有液晶层和用于对液晶层施加电压的大量电极。 [0161] The liquid crystal display 100 operates according to the present embodiment is a normally black mode, and includes a plurality of pixels, each pixel having a liquid crystal layer and a large number of electrodes for applying a voltage to the liquid crystal layer. 虽然此处以TFT液晶显示器为例,但也可以用其它开关元件(如MIM元件)代替。 Although an example here for TFT LCD, but may be replaced with other switching elements (e.g., MIM elements).

[0162] 液晶显示器100具有大量以矩阵分布的象素10。 [0162] The liquid crystal display 100 having a large number of pixels 10 in a matrix distribution. 大量象素10的每一个有液晶层13。 Each has a large number of pixels 10 in liquid crystal layer 13. 另外,象素具有自己的象素电极18和反电极17,以向液晶层13施加电压。 Further, the pixels have their own pixel electrode 18 and the counter electrode 17 to apply voltage to the liquid crystal layer 13. 典型地,反电极17是对所有象素10公用的单电极。 Typically, the counter electrode 17 is a single electrode 10 common to all the pixels.

[0163] 在根据本实施例的液晶显示器100中,大量象素10的每一个具有可以施加互不相同的电压的第一子象素IOa和第二子象素10b,如图1所示。 [0163] In the liquid crystal display 100 according to the present embodiment, a plurality of pixels each having a mutually different voltages can be applied to the first sub-pixels 10 and second sub-pixels IOa 10b, as shown in FIG.

[0164] 当显示满足O彡gk彡gn(此处,gk和gn为不小于零的整数,并且较大的gk值对应于较高的亮度)的灰度时,大量象素的每一个以至少在O <gk Sn-1的范围内满足AV12(gk) >0V 和AV12(gk)》AV12(gk+l)的方式驱动,其中,AV12(gk)=Vl (gk) -V2 (gk)是施加到第一子象素IOa液晶层的方均根电压Vl (gk)和施加到第二子象素10部的液晶层的方均根电压V2(gk)之差。 [0164] When the display satisfied O San gk San gn (here, gk and gn are integers not less than zero and a larger value of gk corresponds to higher brightness) of the gradation, the number of pixels in each at least <satisfies AV12 (gk) in the range of gk Sn-1> in the O 0V and AV12 (gk) "driving AV12 (gk + l) manner, wherein, AV12 (gk) = Vl (gk) -V2 (gk) a first difference is applied to a side of the liquid crystal layer of the subpixel IOa root mean voltage Vl (gk) applied to the second sub-pixels and the liquid crystal layer 10 portion of the root mean square voltage V2 (gk) of.

[0165] 每个象素10拥有的子象素数量(有时称作象素划分的数量)不限于二。 [0165] The number of sub-pixels of each pixel 10 has (sometimes referred to as the number of divided pixels) is not limited to two. 每个象素10还可以有第三子象素(未示出),对其施加不同于第一子象素IOa和第二子象素IOb的电压。 Each pixel 10 may further have a third sub-pixel (not shown), a first voltage and a second sub-pixels IOa different from the sub-pixels IOb applied thereto. 在该情况下,象素构造成如果假设AV13 = Vl(gk)-V3(gk),此处V3(gk)为对第三子象素的液晶层施加的方均根电压,并且为施加给第一子象素的液晶层的方均根电压与施加给第三子象素液晶层的方均根电压之差,则满足OV < AV13(gk) < AV12(gk) [0166] 优选施加到子象素液晶层的方均根电压至少在O < gk < η-l的范围内满足关系AV12(gk) > AV12(gk+l)。 In this case, if it is assumed pixel configured AV13 = Vl (gk) -V3 (gk), side where V3 (gk) is the third sub-pixel of the liquid crystal layer is applied to the root mean voltage, and is applied to the first sub-pixels square of the liquid crystal layer root mean voltage applied to the third sub-pixels of the liquid crystal layer is the root mean square difference of the voltage, is satisfied OV <AV13 (gk) <AV12 (gk) [0166] is preferably applied to the sub-pixels of the liquid crystal layer, rms voltage at least in the range of η-l O of <gk <satisfy the relationship AV12 (gk)> AV12 (gk + l). 因而,优选灰度水平变得越高,施加到第一子象素IOa和第二子象素IOb液晶层的方均根电压之差变得越小。 Thus, preferably the gradation level becomes higher, it is applied to a first side and a second sub-pixels IOa IOb sub-pixels of the liquid crystal layer are voltage difference between the root becomes smaller. 换言之,优选随着灰度水平变低(接近黑色),施加到第一子象素IOa和第二子象素IOb液晶层的方均根电压之差变得越大。 In other words, preferably as the gradation level becomes lower (closer to black), applied to the first side and the second sub-pixel IOa IOb sub-pixels of the liquid crystal layer are voltage difference between the root becomes larger. 另外,如果每个象素有第三子象素,则优选至少在O <gk彡η-l的范围内满足关系AV12(gk) >AV12(gk+l)和AV13(gk) > AV13(gk+l)。 Further, if each pixel has a third sub-pixels, it is preferably <AV12 satisfy the relationship within the range of η-l San gk (gk)> at least O AV12 (gk + l) and AV13 (gk)> AV13 (gk + l).

[0167] 第一子象素IOa的面积等于或小于第二子象素IOb的面积。 [0167] The first sub-pixel area IOa or less of the area of ​​the second sub-pixel IOb. 如果大量象素的每一个有三个或更多的子象素,则优选被施加最高方均根电压的子象素的面积(在此情况下是第一子象素)不大于被施加最低方均根电压的子象素(在此情况下是第二子象素)面积。 If there are a large number of pixels each of three or more sub-pixels, preferably the area of ​​the highest applied rms voltage sub-pixels (in this case the first sub-pixel) is not larger than the minimum root-mean-square voltage is applied sub-pixels (in this case the second sub-pixel) area. 具体地说,如果每个象素10有大量的子象素SP1、SP2、...、和SPn,并且施加到液晶层的方均根电压为Vl (gk)、V2 (gk),和Vn (gk),则优选满足Vl (gk) > V2 (gk)>...>Vn(gk)。 Specifically, if each pixel 10 has a large number of sub-pixels SP1, SP2, ..., SPn and, applied to the liquid crystal layer and the root mean square voltage Vl (gk), V2 (gk), and Vn (gk ), it is preferable to satisfy Vl (gk)> V2 (gk)> ...> Vn (gk). 另外,如果子象素的面积为SSP1、SSP2、...和SSPn,则优选满足SSPl ( SSP2 ^ ^ SSPn。 Further, if the area of ​​the sub-pixels are SSP1, SSP2, ..., and SSPn, it is preferable to satisfy SSPl (SSP2 ^ ^ SSPn.

[0168] 至少如果对于除了最高灰度和最低灰度的所有灰度(即,在O < gk彡η-l的范围内)满足Vl (gk) > V2 (gk) >...> Vn (gk),贝U可以实现本发明。 [0168] If at least for all except the highest gradation and lowest gradation of the gradation (i.e., at O ​​<gk San the range of η-l) satisfy Vl (gk)> V2 (gk)> ...> Vn ( gk), the present invention can be implemented U shellfish. 但是,也可以实施一种对所有灰度(即,在O Sgk Sn的范围内)满足该关系式的结构。 However, all may implement a gray scale (i.e., in the range of O Sgk Sn) satisfy the relation of the structural formula.

[0169] 通过这种方式,如果每个象素被分成大量的子象素,并且对子象素的液晶层施加不同的电压,则获得不同Y特性的混合,因而,可以减小Y特性的视角依赖性。 [0169] In this way, if each pixel is divided into a large number of sub-pixels, sub-pixels and the liquid crystal layer is applied with different voltages, the mixing of the different characteristics of Y obtained, therefore, possible to reduce the characteristic Y the viewing angle dependence. 另外,因为较低灰度的方均根电压差设置得较大,所以在常黑模式的黑侧(低亮度水平处)Y特性的视角依赖性大大减小。 Further, because the lower root mean square voltage gradation difference is set too large, the black side of the normally black mode (the level of the low luminance) Y viewing angle dependency characteristic is greatly reduced. 这在提高显示质量方面非常有效。 This is very effective in improving display quality.

[0170] 可以用不同的结构以满足上述关系式的方式对子象素IOa和IOb的液晶层施加方均根电压。 [0170] Different structures may be used to satisfy the above relational expression sub-pixels of the liquid crystal layer IOb IOa and root mean square voltage is applied.

[0171] 例如,液晶显示器100可以如图1所示构成。 [0171] For example, a liquid crystal display 100 may be configured as shown in FIG. 1. 具体地说,在常规液晶显示器100'中,象素10仅有一个象素电极18经TFT 16连接到信号线14上,而液晶显示器100有两个子象素电极18a和18b分别经TFT 16a和16b连接到不同的信号线14a和14b上。 Specifically, in the '100 in the conventional liquid crystal display, the pixel 10 has only one pixel electrode 18 via the TFT 16 is connected to the signal line 14, the liquid crystal display 100 has two sub-pixel electrodes 18a and 18b, respectively, via the TFT 16a and 16b connected to different signal lines 14a and 14b. [0172] 因为子象素IOa和IOb组成一个象素10,所以TFT16a和16b的栅极连接到公共扫描线(栅极线)12上,并通过公共扫描信号开和关。 [0172] Because the sub-pixels form a pixel IOb IOa and 10, and so TFT16a gate 16b connected to a common scanning line (gate line) 12, and by a common scan signal on and off. 对信号线(源极总线)14a和14b供给满足上述关系的信号电压(灰度电压)。 A signal line (source bus line) 14a and 14b is supplied to meet signal voltage (gradation voltage) above relationship. 优选TFT16a和16b的栅极构造成公共栅极。 Preferably TFT16a gate structure 16b and into the common gate.

[0173] 或者,在第一子象素和第二子象素每个包括由电连接到子象素电极的存储电容电极、绝缘层和经绝缘层与存储电容电极相对的存储电容反电极形成的存储电容的结构中(后面描述),优选提供彼此电绝缘的第一子象素和第二子象素的存储电容反电极,并且通过改变供给存储电容反电极的电压(称作存储电容反电极电压)来改变施加到第一子象素液晶层的方均根电压和施加到第二子象素液晶层的方均根电压。 [0173] Alternatively, the first sub-pixel and the second sub-pixel each comprise storage capacitor electrode connected electrically to the sub-pixel electrode, the insulating layer and the insulating layer via electrode and the storage capacitor counter electrode opposing the storage capacitor is formed in the configuration of the storage capacitor (described later), electrically insulated from each other is preferably provided a first sub-pixel and the second sub-pixel storage capacitor counter electrodes, and by varying the supply voltage of the storage capacitor counter electrode (referred to as a storage capacitor trans electrode voltage) applied to the first subpixel changes the liquid crystal layer and the root mean square voltage applied to the liquid crystal layer of the second sub-pixel rms voltage. 通过调节存储电容的值和供给存储电容反电极的电压大小,可以控制施加到子象素液晶层的方均根电压的大小。 By adjusting the value and the magnitude of the voltage supplied to the storage capacitor counter electrode of the storage capacitor can be controlled is applied to the liquid crystal layer of the subpixel root mean square magnitude of the voltage.

[0174] 在此结构中,因为不需要对子象素电极18a和18b施加不同的信号电压,所以TFT三16a和16b可以连接到公共信号线上,并且可以对它们供给相同的信号电压。 [0174] In this structure, since no sub-pixel electrodes 18a and 18b apply different signal voltages, the three TFT 16a and 16b may be connected to a common signal line, and may be the same signal voltage is supplied to them. 因此,信号线的数量在图3所示常规液晶显示器100'的情况下相同,并且可以利用与常规液晶显示器100'有相同结构的信号线驱动电路。 Thus, the number of signal lines 'of the same case, and may utilize the conventional liquid crystal display 100' shown in Figure 3 a conventional liquid crystal display device 100 has the same configuration as the signal line driver circuit. 当然,因为TFT三16a和16b连接到同一扫描线上,所以优选与上述实例的情况一样,共享公共栅极。 Of course, since the three TFT 16a and 16b connected to the same scan line, it is preferable that as in the case of the above example, share a common gate.

[0175] 优选本发明应用到采用垂直排列的液晶层的液晶显示器,其中液晶层包含具有负介电各向异性的向列相液晶材料。 [0175] The present invention is preferably applied to a liquid crystal layer is vertically aligned liquid crystal display, wherein the liquid crystal layer comprises a negative dielectric anisotropy nematic liquid crystal material. 特别是,优选每个子象素的液晶层包含四个在方位角方向分开大约90°的畴,当施加电压时液晶分子就倾斜(MVA)。 Particularly, preferred liquid crystal layer of each sub-pixel comprises four separate domains of about 90 ° in the azimuthal direction, when a voltage is applied to the liquid crystal molecules are inclined (MVA). 或者,每个子象素的液晶层在施加电压时维持轴向对称地排列(ASM)。 Alternatively, each sub-pixel of the liquid crystal layer is maintained when voltage is applied axially symmetrically aligned (ASM).

[0176] 下面对于MVA液晶显示器100更详细地描述本发明的实施例,其中每个子象素的液晶层包含四个在方位角方向分开大约90°的畴,当施加电压时液晶分子就倾斜。 [0176] Embodiments of the present invention for MVA liquid crystal display 100 described in more detail, wherein the liquid crystal layer of each sub-pixel comprises four separate domains of about 90 ° in the azimuthal direction, when a voltage is applied to the liquid crystal molecules are inclined.

[0177] 如图2A所示,MVA液晶显示器100包括液晶板10A、安装在液晶板IOA两侧的相位差补偿元件(典型地为相位差补偿板)20a和20b、将补偿板夹在中间的偏振片30a和30b、以及背光组件40。 [0177] As shown in FIG. 2A, MVA liquid crystal display 100 includes a liquid crystal panel 10A, phase difference compensating elements (typically a phase difference compensation plate) installed on both sides of the liquid crystal panel IOA 20a and 20b, the compensation plate sandwiching polarizing plates 30a and 30b, and a backlight assembly 40. 偏振片30a和30b的透射轴(也称作偏振轴)彼此正交(尼科尔分布),以至于对液晶板IOA的液晶层(未示出)不施加电压(垂直排列状态)时显黑。 When the polarizing plate 30a and the black significant transmission axis 30b (also known as polarization axes) orthogonal to each other (Nicole distribution), so that the liquid crystal panel IOA crystal layer (not shown) voltage (homeotropic alignment state) is not applied . 提供相位差补偿元件20a和20b以改善液晶显示器的视角特性,并利用已知技术优化设计。 Phase difference compensating elements 20a and 20b to improve the viewing angle characteristics of a liquid crystal display, using known techniques and design optimization. 具体地说,已经优化(gk = O)为将正面观察和以任意方位角斜视时的亮度(黑色水平)差减为最小。 Specifically, it has been optimized (gk = O) is the front view and the brightness (black level) at any azimuth difference perspective minimized. 当以这种方式优化相位差补偿元件20a和20b时,本发明可以产生更大的视场效应。 In this manner, when the optimum phase difference compensating elements 20a and 20b, the present invention may have a greater visual field effect.

[0179] 下面参考图2A〜2C描述MVA液晶显示器100中的象素结构。 [0179] Referring to FIG 2A~2C pixel structure 100 described in the MVA liquid crystal display. 例如在日本待公开专利申请JPl 1-242225中描述了MVA液晶显示器的结构和工作。 For example, in Japanese Patent Application Laid-open structure and operation described MVA liquid crystal display 1-242225 JPl.

[0180] 如参考图1所述,MVA液晶显示器100中的象素10有两个子象素IOa和10b,子象素中的子象素IOa具有子象素电极18a,子象素IOb具有子象素电极18b。 [0180] As described with reference to FIG 1, the pixel 100 MVA liquid crystal display 10 has two sub-pixels IOa and 10b, the sub-pixel having subpixels IOa sub-pixel electrode 18a, the sub-pixel having a sub-IOb the pixel electrode 18b. 如图2C所示,形成在玻璃基底Ila上的子象素电极18a(和子象素电极18b(未不出))具有狭缝18s,并与放置成与子象素电极18a隔液晶层13相对的反电极17 —起形成倾斜电场。 2C, the sub-pixel electrode 18a is formed (and the sub-pixel electrode 18b (not not)) on a glass substrate having a slit 18S Ila, and is placed in the sub-pixel electrode 18a and the liquid crystal layer 13 opposing spacer counter electrode 17-- oblique electric field from forming. 另外,在玻璃基底Ilb的安置了反电极17的表面上设置凸向液晶层13的肋19。 Further, the rib provided to the liquid crystal layer 13 on the surface of the glass substrate 19 is placed Ilb counter electrode 17. 液晶层13由具有负介电各向异性的向列相液晶材料制成。 An anisotropic liquid crystal layer 13 made of nematic liquid crystal having a negative dielectric material is made. 不施加电压时,其通过覆盖反电极17、肋19和子象素电极18a和18b的垂直排列膜(未示出)近乎垂直地排列。 When no voltage is applied, which is 17, the ribs 19 and the sub-pixel electrodes 18a and 18b of the vertical alignment film (not shown) to cover the counter electrode are arranged approximately vertically. 垂直排列的液晶分子通过肋19表面(倾斜面)和倾斜电场在预定的方向上安稳地铺设。 And vertically aligned liquid crystal molecules are laid in oblique electric field secure a predetermined direction by rib 19 surfaces (inclined surface).

[0181] 如图2C所示,肋19以形成一角度的方式向其中心倾斜。 [0181] 2C, the manner of ribs 19 to form an angle tilted toward the center. 液晶分子近乎垂直于倾斜面地排列。 Liquid crystal molecules are aligned almost perpendicular to the inclined surface to. 因而,肋19决定液晶分子的倾角(由基底表面与液晶分子的长轴形成的角度)分布。 Thus, the ribs 19 determines the tilt angle of the liquid crystal molecules (the angle formed by the major axis of the liquid crystal molecules of the substrate surface) profile. 狭缝18s规律地改变施加到液晶层的电场的方向。 Slit 18s regularly changes the direction of the electric field applied to the liquid crystal layer. 因此,当施加电场时,液晶分子通过肋19和狭缝18在图中箭头所示的四个方向右上、左上、左下和右下排列,提供垂直和水平对称的、良好的视角特性。 Therefore, when the electric field is applied in four directions of the arrows shown in FIG upper right, upper left, lower left and lower right arrangement of ribs 19 and the slits 18 of the liquid crystal molecules, providing vertically and horizontally symmetrical, good viewing angle characteristics. 液晶板IOA的矩形显示表面以其较长的尺度水平放置和偏振片30a的透射轴平行于较长尺度放置来典型地取向。 IOA rectangular display surface of the liquid crystal panel with its longer dimension placed horizontally and the transmission axis of the polarizing plate 30a placed parallel to the longer dimension is typically oriented to. 另一方面,象素10以其较长尺度正交于液晶板IOA的较长尺度来典型地取向,如图2B所示。 On the other hand, the pixel 10 with its longer dimension orthogonal to the longer dimension of the liquid crystal panel is typically oriented to IOA, shown in Figure 2B.

[0182] 优选,如图2B所示,第一子象素IOa和第二子象素IOb的面积实际上相等,每个子象素包含在第一方向延伸的第一肋和在第二方向上延伸的第二肋,每个子象素中的第一肋和第二肋相对于平行于扫描线12的中心线对称放置,并且其中一个子象素中的肋分布与另一个子象素中的肋分布相对于正交于扫描线12的中心线对称。 [0182] Preferably, as shown in FIG. 2B, the first sub-pixel and a second sub-pixels IOb IOa of substantially equal area, each sub-pixel comprises a first rib extending in a first direction and in a second direction a second rib extending in the first sub-pixels in each rib and the second rib are placed symmetrically relative to the center line 12 parallel to the scan lines, and wherein a sub-pixel distribution rib of the other sub-pixels distribution ribs with respect to the center line orthogonal to the scanning line 12 of symmetry. 此种分布导致每个子象素中的液晶分子在四个方向右上、左上、左下和右下上分布,并且使得在包含第一子象素和第二子象素的整个象素中液晶畴的面积实际上相等,提供垂直和水平对称以及良好的视角特性。 Such distribution results in each sub-pixel of the liquid crystal molecules in four directions of the upper right, upper left, lower left and lower right distribution, and so that all of the pixels comprises a first sub-pixel and the second sub-pixels of the liquid crystal domains substantially equal area, providing vertically and horizontally symmetrical, and good viewing angle characteristics. 另外,优选在每个子象素中平行于公共扫描线的中心线以近似等于扫描线阵列间距一半的间隔放置。 Further, preferably parallel to the centerline of each sub-pixel to the common scan line is approximately equal to half the pitch of the array of scan lines of spaced-apart.

[0183] 接下来,对根据本发明实施例的液晶显示器100的工作及显示特性进行描述。 [0183] Next, a liquid crystal display according to the work described in the embodiment of the present invention 100 and display characteristics.

[0184] 首先,参见图4,对与图3所示常规液晶显示器100'有相同电极结构的MVA液晶显示器的显示特性给予描述。 [0184] First, referring to FIG. 4, the display characteristics of the conventional liquid crystal display 100 as shown in 'FIG. 3 MVA and have the same electrode structure of a liquid crystal display is described given. 顺便说一下,对根据本发明实施例的液晶显示器100中子象素IOa和IOb (即子象素电极18a和18b)的液晶层施加相同方均根电压所获得的显示特性近似等于常规液晶显示器的显示特性。 Incidentally, the same manner is applied to the liquid crystal display pixel 100 neutrons and IOb IOa according to embodiments of the present invention (i.e., the sub-pixel electrodes 18a and 18b) of the liquid crystal layer of the display characteristic root mean approximately equal to the voltage obtained by the conventional liquid crystal display display characteristic.

[0185] 图4A是从前侧(NI)、右侧60° (LI)和从右上60° (LUl)观看显示时的透射率与施加电压的依赖关系。 [0185] FIG. 4A is a front side (NI), the right side 60 ° (LI) and the upper right 60 ° (LUl) viewing display transmittance dependence of applied voltage. 图4B是以应用最高灰度电压(显示白色所需的电压)获得的透射率为100%规一化之后图4A中所示的三个透射率曲线。 4B is the maximum gray-scale voltage application of FIG. (Desired white display voltage) three transmittance curve shown in transmittance after 100% was obtained normalized Figure 4A. 其表示三种条件下:正视状态(N2)、右侧60° (L2)和从右上60° (LU2)规一化的透射率与施加电压的关系:正视状态(N2)、右侧60° (L2)和从右上60° (LU2)。 Which represents the three conditions: a front state (N2), right side 60 ° relationship (L2 of) the right and 60 ° (LU2) normalized transmittance and applied voltage: front state (N2), right side 60 ° (L2) and the upper right 60 ° (LU2). 顺便说一下,“60° ”是指与显示表面法线夹60°的角。 Incidentally, "60 °" means the angle of the surface with the display method of the clip 60 °.

[0186] 从图4B可以看出,正视的显示特性不同于右侧60°和右上侧60°的显示特性。 [0186] As can be seen from Figure 4B, the display characteristics different from the display characteristics of the front right and right side 60 ° 60 °. 这表明Y特性依赖于观察方向。 This indicates that Y depends on the characteristics of the viewing direction.

[0187] 图4C更清晰地表示Y特性的差异。 [0187] FIG. 4C showing more clearly the difference in the Y character. 为了清晰地表示Y特性的差异,水平轴代表(正视规一化的透射率/100) ~ (1/2.2),而竖直轴代表N3、L3和LU3状态下的灰度特性:正视灰度特性=(正视规一化的透射率/100) ~ (1/2.2),右侧60°视角灰度特性=(右侧60°规一化的透射率/100) ~ (1/2.2),右上侧60°视角灰度特性=(右上侧60°规一化的透射率/100)~(1/2.2),此处表示指数,指数的倒数对应于Y值。 To clearly indicates the characteristics of the difference Y, the horizontal axis represents (front normalized transmittance / 100) - (1 / 2.2), and the gradation characteristics at the vertical axis represents N3, L3 and LU3 state: front gradation = characteristic (front normalized transmittance / 100) - (1 / 2.2), right side 60 ° viewing angle gradation characteristics = (right side 60 ° normalized transmittance / 100) - (1 / 2.2), 60 ° viewing angle gradation characteristic = upper right (upper right 60 ° normalized transmittance /100)~(1/2.2), where the exponent corresponding to the inverse of an exponential Y value. 在典型的液晶显示器中,正视灰度特性的Y值设为2.2。 In a typical liquid crystal display, Y is the value of the gradation characteristic is set to face 2.2.

[0188] 参见图4C,在正视状态(N3)下横坐标值与纵坐标值重合,因而此状态(N3)下的灰度特性为线性。 [0188] Referring to Figure 4C, the (N3) to the abscissa value ordinate values ​​coincide front state, and thus the gradation characteristic in this state (N3) are linear. 另一方面,右侧60°视角灰度特性(L3)和右上侧60°视角灰度特性(LU3)为曲线。 On the other hand, the right side 60 ° viewing angle gradation characteristics (L3) and the upper right 60 ° viewing angle gradation characteristics (LU3) is curved. 正视状态(N3)下曲线(L3和LU3)与直线的偏差量化地代表Y特性的各个偏差,即灰度显不的偏差(差异)。 State deviation face (N3) the curves (L3 and LU3) and Y represents linear quantization characteristics of the respective deviation, i.e., the gradation is not significant deviation (difference).

[0189] 本发明旨在减小常黑液晶显示器中的这种偏差。 [0189] The present invention is intended to reduce such deviations normally black liquid crystal display. 理想的情形是,代表右侧60°视角灰度特性(L3)和右上侧60°视角灰度特性(LU3)的曲线(L3和LU3)与代表正视灰度特性(N3)的直线重合。 The ideal situation is that the right represents 60 ° viewing angle gradation characteristics (L3) and the upper right 60 ° viewing angle gradation characteristics (LU3) curves (L3 and LU3) representing the linear gradation characteristic (N3) is a front view coincides. 下面将参考附图评估改善Y特性的效果,其中附图表示Y特性的差异,如同图4C所示的情形。 Below with reference to the accompanying drawings assess the effect of improving the properties of Y, where Y represents the difference reference characteristic, like the case shown in FIG. 4C.

[0190] 参见图4B,下面将对本发明如何可以通过在每个象素中设置第一子象素和第二子象素并对子象素的液晶层施加不同的方均根电压来减小Y特性的偏差的主要原理给予描述。 [0190] Referring to Figure 4B, description will be how the invention can be provided by the characteristics of the liquid crystal layer of the first Y sub-pixel and the second sub-pixels and sub-pixels in different ways applied to each pixel to reduce the voltage root-mean the main principle of the deviation of the description given. 假设此处第一子象素和第二子象素具有相同的面积。 Here it is assumed that the first sub-pixel and the second sub-pixel has the same area.

[0191] 对于常规的液晶显示器100',在由点NA代表正视透射率的电压处,右侧60°视角透射率由点LA表示,其中点LA代表与NA相同电压的右侧60°视角透射率。 [0191] For the conventional liquid crystal display 100 ', the voltage at a transmittance of a front node NA representatives, 60 ° viewing angle transmittance of the right point LA, where the right point 60 ° Angle LA represents the same voltage transmission NA rate. 关于本发明,要获得与点NA相同的正视透射率,可以将第一子象素和第二子象素的正视透射率分别设置在点NBl和NB2。 About the present invention, to obtain the same front node NA transmittance, the first sub-pixels and the front transmittance of the second sub-pixels are disposed at the point NBl and NB2. 因为点NB2处的正视透射率近似为零,并且第一子象素和第二子象素具有相同的面积,所以NBl处的正视透射率是点NA处正视透射率的两倍。 Because the front transmittance at point NB2 is approximately zero, and the first sub-pixel and the second sub-pixels have the same area, the transmittance of the front node NA is NBl at twice the transmittance at the front. 点NBl和NB2之间的方均根电压之差为AV12。 Side between points NBl and NB2 root mean difference of the voltage of AV12. 此外,对于本发明,右侧60°视角透射率由点P代表,其作为分别与点NBl和NB2相同电压处的右侧60°视角透射率LBl和LB2的平均值。 Furthermore, with the present invention, the transmittance of the viewing angle 60 ° right point represents P, as the right point NBl and NB2 are the same as the voltage at the 60 ° viewing angle transmittance LBl and LB2 average.

[0192] 对于根据本发明的液晶显示器,代表右侧60°视角透射率的点P比代表常规液晶显示器100'的右侧60°视角透射率的点LA更接近代表对应的正视透射率的点NA。 [0192] For the liquid crystal display of the present invention, the conventional liquid crystal display representative point 60 ° Angle P transmittance right than the right side 100 'of the 60 ° point of the transmittance of LA perspective front view of the transmittance of the nearer the point corresponding to the representative NA. 这意味着Y特性的偏差减小。 This means that the characteristics of the Y deviation is reduced.

[0193] 从上述可以看出,第二子象素的右侧60°视角透射率(见点LB2)接近零的事实增强了本发明的效果。 [0193] As can be seen from the above, the right side of the second sub-pixels 60 ° viewing angle transmittance (see point LB2) close to zero fact enhances the effect of the present invention. 因而,要增强本发明的效果,优选控制斜视黑屏时透射率的增加。 Thus, to enhance the effect of the present invention, it is preferable to increase the transmittance of a control perspective when the blank. 从.此观点出发,优选根据需要安装如图2A所示的相位差补偿元件20a和20b,从而控制斜视黑屏时透射率的增加。 From this viewpoint, it is preferable to install necessary retardation compensation element illustrated in FIG. 2A 20a and 20b, thereby controlling the transmittance is increased perspective when black.

[0194] 根据本发明的液晶显示器100通过对每个象素10中各个子象素IOa和IOb的两个液晶层施加不同的方均根电压来改善Y特性。 [0194] The liquid crystal display 100 according to the present invention by applying different ways for each pixel 10 in each of two sub-pixels and the liquid crystal layer IOa IOb root mean voltage Y to improve the properties. 这样做时,施加到子象素IOa和IOb的各个液晶层的方均根电压之差AV12(gk) = Vl (gk) 一V2(gk)设置成满足AV12(gk) > OV和AV12(gk) ^ AV12(gk+l)。 Thus doing, it is applied to the subpixel IOa and IOb the respective liquid crystal layers of the root mean square difference between the voltage AV12 (gk) = Vl (gk) a V2 (gk) is arranged to satisfy AV12 (gk)> OV, and AV12 (gk) ^ AV12 (gk + l). 下面将描述在O <gk Sn的整个范围内满足上述关系的情形。 The following scenario satisfy the above relation in the entire range of O <gk Sn will be described.

[0195] 图5A〜表示施加到图1所示象素10的第一子象素IOa的液晶层的方均根电压Vl(gk)和施加到第二子象素IOb的液晶层的方均根电压V2(gk)之间的多种关系。 [0195] FIG 5A~ showing a first applied to the pixel sub-pixels IOa 10 shown in Figure 1 of the liquid crystal layer side of the root mean voltage Vl (gk) applied to the liquid crystal layer and a second sub-pixels IOb the root mean square voltage V2 ( multiple relationships between gk).

[0196] 在图5A所示的电压施加状态A下,向两个子像素IOa和IOb的液晶层施加相同的电压(VI = V2)。 Under [0196] A voltage applied to the state shown in FIG. 5A, the same voltage (VI = V2) is applied to two sub-pixels of the liquid crystal layer IOa and IOb. 因而,Δ V12 (gk) = OV。 Thus, Δ V12 (gk) = OV.

[0197] 在图5B所示的电压状态B下,保持关系Vl >V2,并且V12为与Vl值无关的常数。 [0197] In FIG 5B voltage state B shown holding relationship Vl> V2, and V12 is constant regardless of the value Vl. 因而,在电压状态B下,对任何灰度gk满足关系AV12(gk) = AV12(gk+l)0该实施例采用AV12(gk) = 1.5V作为典型值,当然,也可以采用其它值。 Thus, at a voltage state B, satisfy the relationship AV12 any gradation gk (gk) = AV12 (gk + l) 0 This embodiment employs AV12 (gk) = 1.5V as a representative value, of course, other values ​​may be used. 较大的AV12(gk)值增强了本发明的效果,但是造成白模式中降低的亮度(透射率)的问题。 Larger AV12 (gk) enhances the value of the effect of the present invention, but the resulting luminance (transmittance) in white mode problems reduced. 另外,当AV12(gk)的值超过液晶显示器的透射率的阈值电压(即图4B所示的Vth)时,黑模式的亮度(透射率)增加,显示对比度减小,这是个问题。 Further, when (Vth i.e., shown in FIG. 4B) the threshold voltage value AV12 (gk) exceeds the transmittance of the liquid crystal display, the brightness of the black pattern (transmittance) is increased, the display contrast is reduced, this is a problem. 因此,优选的是AV12(gk) ^ Vth0 Accordingly, it is preferable that AV12 (gk) ^ Vth0

[0198] 在图5C所示的电压状态C下,保持关系Vl > V2,并且Λ V12随着Vl的增加而减小。 [0198] Under voltage condition C shown in FIG. 5C, the holding relationship Vl> V2, and Λ V12 decreases with increasing Vl. 因而,在电压状态C下,对任何灰度gk满足关系AV12(gk) > AV12(gk+l)0[0199] 该实施例采用AV12(0) = 1.5V和AV12(n) = OV作为典型值,当然,也可以采用其它值。 Thus, at a voltage state C, satisfy the relationship of any gradation AV12 gk (gk)> AV12 (gk + l) 0 [0199] This embodiment employs AV12 (0) = 1.5V and AV12 (n) = OV as a representative value, of course, other values ​​may be used. 然而,如上所述,优选的是在斜视期间从显示对比度的设定点起AV12(gk) ^Vth,优选的是从白模式中亮度的设定点起AV12(n) =0V。 However, as described above, it is preferable that the contrast during oblique setpoint from AV12 (gk) ^ Vth, is preferred from the display brightness setpoint from AV12 (n) = 0V from white mode.

[0200] 在图所示的电压状态D下,保持关系Vl >V2,并且Λ V12随Vl的增大而增大。 [0200] Under voltage condition D shown in FIG holding relationship Vl> V2, and Λ V12 increases with increasing Vl. 因而,在电压状态D下,对任何灰度gk保持AV12(gk) < AV12(gk+l)0 Accordingly, in the voltage state D, holding AV12 (gk) <AV12 (gk + l) for any grayscale gk 0

[0201] 本实施例采用AV12(0)= OV以及AV12(n) = 1.5V作为典型值。 [0201] The present OV and AV12 (n) = 1.5V as being representative embodiment employs AV12 (0) =.

[0202] 在根据本发明实施例的液晶显示器100中,对子象素IOa和IOb的液晶层施加电压,使得将满足电压状态B或电压状态C。 [0202] In the voltage applied to the liquid crystal display according to an embodiment of the present invention 100, the sub-pixel of the liquid crystal layer IOa and IOb, satisfying such voltage state B or state C. voltage 顺便说一下,虽然在图5B和图5C中对于所有灰度满足AV12(gk) > 0,但是在最佳灰度或最高灰度的情况下AV12 = O均成立。 By the way, although satisfying AV12 (gk)> 0 in Fig. 5B and 5C for all gray, but in the case of the best or highest gray gray AV12 = O are true.

[0203] 下面将参考图6描述电压状态A〜D下MVA液晶显示器的灰度特性。 [0203] will be described with reference to FIG gradation characteristics of the MVA liquid crystal display under voltage conditions A~D 6. 图6A和6B中的水平轴代表(正视规一化的透射率/100) ~ (1/2.2),图6A中的竖直轴代表(右侧60°规一化的透射率/100) ~ (1/2.2),图6B中的竖直轴代表(右上侧60°规一化的透射率/100) ~ (1/2.2)。 The horizontal axis represents FIGS. 6A and 6B (front normalized transmittance / 100) (1 / 2.2) (60 ° right transmittance of normalized / 100) - the vertical axis represents FIGS. 6A ~ (1 / 2.2), the vertical axis represents FIG. 6B (upper right 60 ° normalized transmittance / 100) - (1 / 2.2). 图中还示出了代表正视灰度特性的直线一并用于参考。 The figure also shows a front view of the representative gradation characteristics linear collectively for reference.

[0204] 在电压状态A下,对子象素IOa和IOb的液晶层施加相同的电压(AV12(gk)=O)。 [0204] Under voltage condition A, the sub-pixel of the liquid crystal layer IOb IOa and applying the same voltage (AV12 (gk) = O). 如图6A和6B所示,与图4中所示常规液晶显示器一样,Y特性极大地偏离。 As shown in FIG. 6A and 6B, as in the conventional liquid crystal display shown in FIG. 4, Y greatly offset characteristic.

[0205] 电压状态D对减小Y特性的视角依赖性的影响小于电压状态B和C的情形。 Effects [0205] D voltage state to reduce the viewing angle dependence characteristics of Y is less than the case where B and C voltage state. 例如,电压状态D对应于利用日本待公开专利申请JP6-332009中描述的常规容量划分划分的象素的电压状态。 For example, the voltage state corresponding to the voltage state of D pixels by dividing a capacity of a conventional Japanese Laid-Open Patent Application JP6-332009 described. 虽然在常白模式下对改善视角特性有影响,但对常黑模式下减小Y特性的视角依赖性没有很大的影响。 Although an effect on improving the viewing angle characteristics in normally white mode, but without significant effect on reducing the viewing angle dependence characteristic Y in the normally black mode.

[0206] 如上所述,优选电压状态B或C用于减小常黑模式下Y特性的视角依赖性。 [0206] As described above, preferably voltage condition B, or C for the viewing angle dependency characteristic Y under reduced normally black mode.

[0207] 接下来,参见图7,对电压状态中白色模式透射率、即施加最高灰度电压时的变化进行描述。 [0207] Next, referring to FIG. 7, the voltage state transmittance white mode, i.e., when applied to the highest gradation voltage variation will be described.

[0208] 白模式中的透射率在电压状态B和D下自然低于在电压状态A下的情形。 [0208] The transmittance in white mode under voltage conditions B and D in the case where a voltage lower than the natural state A. 电压状态C下白色模式的透射率等于电压状态A下的透射率。 Voltage state C is equal to the transmittance of the white mode voltage state transmittance at A. 在此方面,电压状态C最好是电压状态B和D。 In this respect, voltage condition C is preferably voltage condition B, and D. 因而,考虑到Y特性的视角依赖性以及白模式中的透射率,可以说电压状态C更优越。 Thus, considering the viewing angle dependence of the transmittance characteristics and a Y white mode can be said that voltage condition C is superior.

[0209] 接下来描述子象素之间的优选面积比。 [0209] Next described area ratio between the sub-pixels.

[0210] 根据本发明,如果施加到子象素SP1、SP2、…和SPn的液晶层的方均根电压为V1、V2、…Vn,如果子象素的面积为SSP1、SSP2、…和SSPn,并且如果保持关系Vl >Ί2>."Vn,则优选满足SSPl ( SSPn。后面将有描述。 [0210] According to the present invention, if applied to the sub-pixels SP1, SP2, ..., and side SPn liquid crystal layer root mean voltages V1, V2, ... Vn, if the area of ​​the sub-pixels are SSP1, SSP2, ..., and SSPn, and If the holding relationship Vl> Ί2>. "Vn, it is preferable to satisfy SSPl (SSPn. there will be described later.

[0211] 假设SSPl和SSP2是图1所示象素10中子象素IOa和IOb的面积。 [0211] Suppose SSPl and SSP2 are the neutron pixels 10 pixels and IOb IOa area shown in FIG. 图8比较了电压状态C 下面积比(SSPI: SSP2) = (1: 3)、(1: 2)、(1:1)、(2:1)、(3:1)之间的Y特性。 Figure 8 compares the voltage state C area ratio (SSPI: SSP2) = (1: 3), (1: 2) Y characteristic between: (13), (1:: 1), (21), . 图8A表示右侧视角的Y特性,图8B表示右上侧视角的Y特性。 8A shows right viewing angle characteristics of Y, Y 8B shows viewing angle characteristics of upper right side. 图9表示不同狭縫比的正视透射率。 9 shows a front view of a slit of different transmissivity ratio.

[0212] 从图8中可以看出,被施加较高电压的子象素(IOa)的面积比的减小对减小Y特性的视角依赖性更有效。 [0212] As can be seen from Figure 8, the sub-pixel (IOa of) a higher voltage is applied to decrease the area ratio Y is more effective in reducing the viewing angle dependence characteristics.

[0213] 当面积比(SSP1: SSP2) = (1:1)时白模式中的透射率取最大值,并随着面积比变得不均匀而降低。 [0213] When the area ratio (SSP1: SSP2) =: the transmittance in white mode takes the maximum value (11), and as the area ratio becomes uneven reduced. 这是因为如果面积比变得不均匀,则不再能得到良好的多畴垂直排列,从而减小了第一子象素和第二子象素的面积。 This is because if the area ratio becomes uneven, it is no longer able to obtain a good multi-domain vertical alignment, thereby reducing the area of ​​the first sub-pixel and the second sub-pixels. 这种趋势在具有小象素面积的高分辨率液晶显示器中得到断定。 This trend is determined, at the high-resolution liquid crystal display having a small area of ​​a pixel. 因而,虽然优选面积比为1: 1,但考虑到减小对Y特性的视角依赖性、白模式中的透射率以及液晶显示器的利用等的影响,可以根据需要调节。 Thus, although the area ratio is preferably 1: 1, but taking into account the influence of reducing the viewing angle dependence characteristics of the Y, the transmittance in white mode, and the like using the liquid crystal display can be adjusted according to need.

[0214] 接下来将描述象素的划分数。 [0214] Next, the division number of pixels will be described.

[0215] 虽然对于图1所示的液晶显示器100,象素10由两个子象素(IOa和IOb)组成,但本发明不限于此,子象素的数量可以为三个或更多。 [0215] Although the liquid crystal display 100 shown by the two sub-pixels 10 pixels (IOa of and IOb of) the composition to Figure 1, but the present invention is not limited thereto, the number of sub-pixels may be three or more.

[0216] 图10比较在三种电压状态下获得的Y特性:象素被分成两个子象素;象素被分成四个子象素;和象素不被划分。 [0216] FIG. 10 Y characteristic comparison voltage obtained in three states: the pixel is divided into two sub-pixels; pixel is divided into four sub-pixels; and the pixel is not divided. 图1OA表示右侧视角的Y特性,图1OB表示右上侧的视角Y特性。 FIG 1OA right viewing angle characteristics of a Y, Y FIG 1OB shows the viewing angle characteristics of upper right. 图11表示白模式中液晶显示器的对应透射率。 Figure 11 shows a corresponding transmittance in white mode liquid crystal display. 象素的面积恒定,并且采用了电压状态B。 Constant area of ​​the pixel, and using voltage state B.

[0217] 从图10中可以看出,子象素数量的增加增大了校正Y特性中的偏差的效果。 [0217] As can be seen from Figure 10, increasing the number of sub-pixels increase the effect of correcting the deviation in the Y character. 与不划分象素相比,一个象素被分成两个子象素时的效果尤其得以肯定。 Compared with the pixel is not divided, a pixel is divided into two sub-pixels effect in particular is affirmative. 当划分的数量从两个上升到四个时,虽然在Y特性的偏差上没有很大的差异,但就与灰度变化有关的偏差的平稳变化而言特性得以改善。 When the division number is increased from two to four, although there is no great difference in the characteristics of the deviation Y, but on the smooth change associated with change in gradation characteristics are improved in terms of the deviation. 但是,从图11中可以看出,白模式中的透射率(正视)随划分数量的增大而下降。 However, it can be seen from FIG. 11, the transmittance (front) white mode with increasing number of divisions decreases. 尤其在划分的数量从两个增加到四个时下降很大。 In particular, a large number of the division fell from two to four time. 这种很大下降的主要原因在于每个子象素的面积如上所述地大大减小。 The main reason is that such a large decline in the area of ​​each sub-pixel is reduced greatly as described above. 比较不划分和划分为二的状态时透射率减小的主要原因在于采用了电压状态B。 Comparison not divided and divided into a main reason the transmittance decreased state that uses two voltage states B. 因而,考虑到对减小Y特性的视角依赖性、白模式中的透射率以及液晶显示器的采用等的影响,可以根据需要调节划分的数量。 Thus, consider the impact on reducing the viewing angle dependence characteristics of Y, the transmittance in white mode, and a liquid crystal display, or the like, the number of partitions can be adjusted as required.

[0218] 从上可以看出,Y特性的偏差、偏差的形状畸变以及Y特性的视角依赖性随象素划分数量的增大而增大。 [0218] As can be seen, the deviation Y characteristics, shape distortion of the deviations Y and viewing angle dependency property with increasing the number of divided pixels is increased. 这些效果在比较不划分象素和象素划分为二(两个子象素)的状态时尤为显著。 These effects are particularly significant when compared to the pixel and the pixel is not divided into two division (two sub-pixels) state. 因而,考虑到由子象素数量的增加以及可制造性的下降导致的白模式透射率的下降,优选将一个象素划分为两个子象素。 Thus, considering the decrease of the number of sub-pixels increase and decrease in manufacturability resulting white mode, transmittance, preferably one pixel is divided into two sub-pixels.

[0219] 在图1所示的液晶显示器100中,子象素IOa和IOb彼此独立地连接到TFT16a和TFT 16b上。 [0219] In the liquid crystal display shown in FIG. 1 100, sub-pixels independently of one another IOa and IOb TFT16a and connected to the TFT 16b. TFT 16a和TFT16b的源电极分别连接到信号线14a和14b上。 TFT16b TFT 16a and the source electrodes are connected to the signal line 14a and 14b. 因而,液晶显示器100允许任何方均根电压施加到子象素的每个液晶层上,但要求是图3所示常规液晶显示器100'的信号线14的两倍(信号线14a和14b),还需要两倍之多的信号线驱动电路。 Thus, the liquid crystal display 100 allows any root-mean-square voltage is applied to the liquid crystal layer of each sub-pixels, but requires twice as shown in FIG. 3 (signal lines 14a and 14b) conventional liquid crystal display 100 'of the signal line 14, but also twice as many signal line drive circuit.

[0220] 相反,根据本发明另一实施例的液晶显示器200具有与常规液晶显示器100'相同数量的信号线,但可以在类似于上述电压状态C的电压状态下对子象素IOa和IOb的液晶层施加互不相同的方均根电压。 [0220] In contrast, the liquid crystal display according to another embodiment of the present invention having a conventional liquid crystal display 200 'are the same number of signal lines 100, but in a state similar to the voltage of the voltage state C of sub-pixels IOa and IOb applied to the liquid crystal layer side of mutually different root-mean voltage.

[0221] 图12表示根据本发明另一实施例的液晶显示器200的电路结构。 [0221] FIG. 12 shows a circuit configuration example of a liquid crystal display device 200 according to another embodiment of the present invention. 具有与图1所示液晶显示器100相同功能的元件采用与对应元件相同的标号并省去描述。 Using elements having the same reference numerals corresponding to the element 100 functions the same liquid crystal display shown in FIG. 1 and description is omitted.

[0222] 象素10被分成子象素IOa和10b,这些子象素分别连接到TFT 16a和TFT16b以及存储电容(CS) 22a和22b上。 [0222] 10 pixels are divided into subpixels IOa and 10b, which are connected to the sub-pixels and TFT16b TFT 16a and the storage capacitor (CS) 22a and 22b. TFT16a和TFT16b的栅电极连接到扫描线12上,源电极连接到公共信号线14上。 TFT16a and TFT16b gate electrode connected to the scanning line 12, a source electrode connected to a common signal line 14. 存储电容22a和22b分别连接到存储电容线(CS总线)24a和24b上。 Storage capacitors 22a and 22b are connected to storage capacitor lines (CS bus line) 24a and 24b. 存储电容22a和22b分别由电连接到子象素电极18a和18b上的存储电容、与存储电容线24a和24b电连接的存储电容反电极以及形成于其间的绝缘层(未示出)形成。 Storage capacitors 22a and 22b are electrically connected to the sub-pixels on the storage capacitor electrodes 18a and 18b, a storage capacitor connected to the storage capacitor lines 24a and 24b and a counter electrode electrically insulating layer formed therebetween (not shown) is formed. 存储电容22a和22b的存储电容反电极彼此独立,并经存储电容线24a和24b被供以互不相同的存储电容反电压。 Storage capacitors 22a and 22b of the storage capacitor counter electrodes independently of each other, and by the storage capacitor lines 24a and 24b are supplied with mutually different storage capacitor counter voltage.

[0223] 接下来,参考附图,对液晶显示器200如何对子象素IOa和IOb的液晶层施加不同的方均根电压的原理给予描述。 [0223] Next, with reference to the accompanying drawings, the principle of applying different root mean square voltage of the description is given of how the sub-pixels of the liquid crystal layer and IOb IOa liquid crystal display 200. [0224] 图13表不液晶显不器200的一个象素的等效电路。 A pixel equivalent circuit [0224] 13 Table does not LCD 200. 在等效电路中,子象素IOa和IOb的液晶层用标号13a和13b表示。 In the equivalent circuit, the sub-pixels of the liquid crystal layer IOa and IOb with numerals 13a and 13b represent. 由子象素电极18a和18b、液晶层13a和13b以及反电极17 (子象素IOa和IOb共用)形成的液晶电容用Clca和Clcb表示。 By the sub-pixel electrodes 18a and 18b, 13a and 13b and the liquid crystal layer, a counter electrode 17 (common subpixel IOa and IOb) formed with a liquid crystal capacitor Clca and Clcb FIG.

[0225] 假设液晶电容Clca和Clcb具有相同的电容值CLC(V)。 [0225] assumed that the liquid crystal capacitors Clca and Clcb have the same capacitance value CLC (V). CLC(V)的值依赖于施加给子象素IOa和IOb的液晶层的方均根电压。 Value (V) is applied to CLC depends on the square sub-pixels of the liquid crystal layer IOa and IOb root mean voltage. 彼此独立地连接到子象素IOa和IOb的液晶电容上的存储电容22a和22b由Ccsa和Ccsb表示,并且假设它们的电容值为CCS。 Independently of one another connected to the storage capacitor 22a to the liquid crystal capacitor of subpixel IOa and IOb and 22b are represented by Ccsa and Ccsb, and a capacitance value thereof is assumed CCS.

[0229] 将参照图4描述图3中的等效电路的工作。 [0229] Work in the equivalent circuit of FIG 34 described with reference to FIG.

[0230] 在Tl时刻,当电压Vg从VgL变到VgH时,TFT 16a和TFT 16b同时导通,并且电压Vs从信号线14传输到子象素IOa和IOb的子象素电极18a和18b,导致子象素IOa和IOb改变。 [0230] at time Tl, when the voltage Vg changes from VgL to VgH, TFT 16a and TFT 16b are simultaneously turned on, and the voltage Vs to the transmission signal line 14 from the sub-pixel electrode 18a and sub-pixels IOa IOb and 18b, leading to sub-pixels change IOa and IOb. 类似的,各个子象素的存储电容Csa和Csb从信号线充电。 Similarly, each sub-pixel storage capacitors Csa and Csb from the signal line charging.

[0231] 在时刻T2,当扫描线12的电压Vg从VgH变为VgL时,TFT 16a和TFT16b同时截止。 [0231] At time T2, when the voltage Vg on the scan line 12 changes from VgH into VgL, TFT 16a is turned off and simultaneously TFT16b. 因此,子象素IOa和IOb以及存储电容Csa和Csb都与信号线14截止。 Thus, sub-pixels IOa and IOb, and the storage capacitor Csa and Csb from the signal line 14 are turned off. 由于TFT 16a和TFT 16b的寄生电容造成的牵引效应,之后,各个子象素的电压Vlca和Vlca即下降近似相同的电压Vd,成为: Since the pulling effect TFT 16a and TFT 16b caused by parasitic capacitance, after each of the sub-pixels and voltages Vlca Vlca i.e., approximately the same voltage Vd is lowered, becomes:

[0232] Vlca = Vs-Vd [0232] Vlca = Vs-Vd

[0233] Vlcb = Vs-Vd [0233] Vlcb = Vs-Vd

[0234] 此时,各条存储电容线的电压Vcsa和Vcsb为: [0234] In this case, the pieces of voltages Vcsa and Vcsb of the storage capacitor line is:

[0235] Vcsa = Vcom-Vad [0235] Vcsa = Vcom-Vad

[0236] Vcsb = Vcom+Vad [0236] Vcsb = Vcom + Vad

[0237] 在时刻T3,连接到存储电容Csa上的存储电容线24a的电压Vcsa从“Vcom_Vad”变为“Vcom+Vad”,连接到存储电容Csb上的存储电容线24b的电压Vcsb从“Vcom+Vad”改变两倍的Vad至“Vcom-Vad”。 [0237] At time T3, the storage capacitor line connected to the storage capacitor Csa voltage Vcsa 24a from "Vcom_Vad" becomes "Vcom + Vad", the storage capacitor line connected to the storage capacitor Csb voltage Vcsb 24b from "Vcom + Vad "change twice Vad to" Vcom-Vad ". 存储电容线24a和24b电压改变的结果是,各个子象素的电压Vlca和Vlcb变为: Results storage capacitor lines 24a and 24b of the voltage change, the voltage of each sub-pixel becomes Vlca and Vlcb:

[0238] Vlca = Vs_Vd+2*Kc*Vad [0238] Vlca = Vs_Vd + 2 * Kc * Vad

[0239] Vlcb = Vs-Vd_2*Kc*Vad [0239] Vlcb = Vs-Vd_2 * Kc * Vad

[0240]此处,Kc = CCS/ (CLC (V) +CCS)) [0240] Here, Kc = CCS / (CLC (V) + CCS))

[0241]在时刻 T4,Vcsa 从“Vcom+Vad” 变为“Vcom-Vad”,Vcsb 从“Vcom-Vad” 改变两倍的Vad 成为“Vcom+Vad”。 [0241] At time T4, Vcsa from "Vcom + Vad" becomes "Vcom-Vad", Vcsb from "Vcom-Vad" change twice Vad becomes "Vcom + Vad". 因此,Vlca 和Vlcb 从:[0242] Vlca = Vs_Vd+2*Kc*Vad Consequently, Vlca and Vlcb from: [0242] Vlca = Vs_Vd + 2 * Kc * Vad

[0243] Vlcb = Vs-Vd_2*Kc*Vad [0243] Vlcb = Vs-Vd_2 * Kc * Vad

[0244]变为: [0244] becomes:

[0245] Vlca = Vs-Vd [0245] Vlca = Vs-Vd

[0246] Vlcb = Vs-Vd [0246] Vlcb = Vs-Vd

[0247]在时刻 T5, Vcsa 从“Vcom-Vad” 改变两倍的Vad,成为“Vcom+Vad”,Vcsb 从“Vcom+Vad” 改变两倍的Vad 成为“Vcom-Vad”。 [0247] At time T5, Vcsa changes from "Vcom-Vad" twice Vad, become "Vcom + Vad", Vcsb from "Vcom + Vad" change twice Vad becomes "Vcom-Vad". 因此,Vlca 和Vlcb 从: Therefore, Vlca and Vlcb from:

[0248] Vlca = Vs-Vd [0248] Vlca = Vs-Vd

[0249] Vlcb = Vs-Vd [0249] Vlcb = Vs-Vd

[0250]变为: [0250] becomes:

[0251] Vlca = Vs_Vd+2*Kc*Vad [0251] Vlca = Vs_Vd + 2 * Kc * Vad

[0252] Vlcb = Vs-Vd_2*Kc*Vad [0252] Vlcb = Vs-Vd_2 * Kc * Vad

[0253] Vcsa、Vcsb、Vlca和Vlcb在T4和Τ5时刻以水平写入时间IH的整数倍的间隔更换上述变化。 [0253] Vcsa, Vcsb, Vlca and Vlcb horizontal writing time T4 and the time Τ5 IH replaced at intervals of an integer multiple of the above changes. 用于更换间隔的整数1、2或3、…可以考虑到液晶显示器的驱动法(极性反转的方法等)和显示条件(闪烁、粒度等)之后按照需要设置。 The replacement interval or an integer of 1, 2, 3, ... may be considered liquid crystal display driving method (method of polarity inversion, etc.) and display conditions after (blinking, size, etc.) is provided as needed. 这些更换周期一直重复到象素10被重写到下一时刻,即,直到等于Tl的时刻。 These replacement cycle is repeated until the pixel 10 is rewritten the next time, i.e., until the time is equal to Tl. 因此,子象素的电压Vlca和Vlcb的有效值为 Thus, voltages Vlca and Vlcb of the sub-pixel values ​​are valid

[0254] Vlca = Vs_Vd+Kc*Vad [0254] Vlca = Vs_Vd + Kc * Vad

[0255] Vlcb = Vs-Vd-Kc^Vad [0255] Vlcb = Vs-Vd-Kc ^ Vad

[0256] 因而,施加到子象素IOa和IOb的液晶层13a和13b的方均根电压Vl和V2为: [0256] Thus, applied to the sub pixel and IOb IOa liquid crystal layers 13a and 13b of the root-mean-square voltages Vl and V2 as:

[0257] Vl = Vlca-Vcom [0257] Vl = Vlca-Vcom

[0258] V2 = Vlcb-Vcom [0258] V2 = Vlcb-Vcom

[0259]结果, [0259] As a result,

[0260] Vl = Vs-Vd+Kc*Vad-Vcom [0260] Vl = Vs-Vd + Kc * Vad-Vcom

[0261] V2 = Vs-Vd-Kc^Vad-Vcom [0261] V2 = Vs-Vd-Kc ^ Vad-Vcom

[0262] 因此,施加到子象素IOa和IOb的液晶层13a和13b的方均根电压之差AV12(=V1-V2)为AV12 = 2*Kc*Vad(此处,Kc = CCS/(CLC (V)+CCS))。 [0262] Thus, applied to the subpixel IOa and IOb liquid crystal layers 13a and 13b of the root mean square difference between the voltage AV12 (= V1-V2) is AV12 = 2 * Kc * Vad (where, Kc = CCS / (CLC ( V) + CCS)). 这意味着可以施加互不相同的电压。 This means mutually different voltage can be applied.

[0263] 根据图12至14所示实施例的Vl和V2之间的关系示于图15。 [0263] According to FIGS. 12 to 14 shown the relationship between Vl and V2 in the embodiment shown in FIG. 15.

[0264] 从图15中可以看出,在根据本实施例的液晶显示器200中,Vl值越小,AV12值就越大。 [0264] As can be seen from FIG. 15, in the liquid crystal display of the present embodiment 200, Vl smaller the value, the greater the value AV12. 这与上述电压状态C下获得的结果类似。 This is similar to the results obtained under the above voltage state C. Λ V12值依据Vl或V2改变的事实归因于液晶电容的电容值CLC (V)。 Based on the fact that Λ V12 values ​​Vl and V2 change due to the capacitance of the liquid crystal capacitance value CLC (V).

[0265] 根据本实施例的液晶显示器200的Y特性示于图16。 [0265] The Y character liquid crystal display 200 of the present embodiment shown in FIG. 16. 为了便于比较,在对子象素IOa和IOb施加相同电压时获得的Y特性也示于图16。 For comparison, Y characteristic obtained when the sub-pixel IOa IOb same voltage is applied and is also shown in FIG. 16. 从图中可以看出,根据本实施例的液晶显示器中Y特性也得到改善。 As can be seen from the figure, the liquid crystal display according to the present embodiment, the Y character also improved.

[0266] 如上所述,本发明的实施例可以改善常黑液晶显示器、尤其是MVA液晶显示器的Y特性。 [0266] As described above, embodiments of the present invention can improve the normally black liquid crystal displays, especially MVA liquid crystal display characteristics of Y. 但是,本发明不限于此,也可以应用到IPS液晶显示器中。 However, the present invention is not limited thereto, and may be applied to IPS liquid crystal displays.

[0267] 接下来,对根据本发明第二方面实施例的液晶显示器进行描述。 [0267] Next, the liquid crystal display according to the second aspect of the embodiment of the present invention will be described.

[0268] 下面对可以减少液晶显示器上“闪烁”的驱动方法或象素分布(子象素阵列)的优选形式给予描述,在象素分布中,每个象素至少有两个显示中间灰度时亮度彼此不同的子象素。 [0268] Next, the liquid crystal display can reduce "flicker" pixel driving method or preferably in the form of (an array of sub-pixels) of the given distribution described, in the pixel distribution in each pixel has at least two intermediate gray display when the luminance of the sub-pixels different from each other. 虽然此处以本实施例的液晶显示器的结构和操作作为具有根据本发明第一方面实施例的划分象素结构的液晶显示器实例进行描述,但象素分布产生的效果不受象素划分的限制,并且也可以采用具有另一种象素划分结构的液晶显示器。 Although described herein in the liquid crystal display of the present embodiment as the structure and operation of a liquid crystal display having a divided pixel structure example of embodiment of the first aspect of the present invention, but the effect is not limited generated pixel arrangement of pixel division, and it may also employ other liquid crystal display having a pixel division structure.

[0269] 首先描述液晶显示器上的“闪烁”问题。 [0269] First described in "flashing" problems in the liquid crystal display.

[0270] 从可靠性出发,典型的液晶显示器设计成使用交变电压作为施加到象素液晶层的电压(有时也称作“ac驱动法”)。 [0270] Starting from the reliability, a typical liquid crystal display is designed to use alternating voltage as the voltage applied to the pixels of the liquid crystal layer (sometimes referred to as "ac driving method"). 象素电极和反电极之间的电势的大小关系以一定的时间间隔反转,并且因此施加到每个液晶层的电场方向(电力线)也以该时间间隔反转。 Magnitude relationship between the potential of the pixel electrode and the counter electrode is reversed at certain time intervals, and thus the direction of an electric field is applied to the (power line) of each liquid crystal layer is also inverted at the interval. 对于反电极和象素电极安置在不同基底上的典型液晶显示器,施加到每个液晶层的电场方向从光源-观察者的方向反转为观察者-光源的方向。 For the counter electrode and the pixel electrode of the liquid crystal display is typically arranged on different substrates, the electric field applied to the liquid crystal layer in each direction from the light source - the direction of the observer is inverted to the observer - in the direction of the light source.

[0271] 典型的情况是,施加到每个液晶层的电场方向反转周期是幀周期(如16.667ms)的两倍(如,33.333ms)。 [0271] Typically, the direction of the electric field applied to the liquid crystal layer of each inversion cycle is twice the frame period (e.g., 16.667 ms) (e.g., 33.333ms). 换言之,在液晶显示器中,施加到每个液晶层的电场方向在每次显示图象(帧图象)改变时反转。 In other words, in the liquid crystal display, the direction of electric field applied to each liquid crystal layer is reversed each time an image (frame images) to change the display. 因而,当显示静态图象时,如果在交变方向的电场强度(施加的电压)不精确地匹配,即如果电场强度在每次电场方向改变时改变,则象素的亮度随电场强度的改变而改变,从而导致显示闪烁。 Accordingly, when displaying a still picture, if the electric field intensity (applied voltage) in alternating directions inexact match, i.e., if the electric field intensity changes at each change the direction of the electric field, the luminance of the pixels changes with the electric field strength The change, resulting in the display flashes.

[0272] 为了防止闪烁,需要在交变方向上精确地使电场强度(施加的电压)相等。 [0272] In order to prevent flicker, it is necessary to accurately make alternating electric field strength in the direction (the applied voltage) are equal. 但是,对于工业生产的液晶显示器,很难使电场强度在交变方向上相等。 However, for industrial production of liquid crystal displays, it is difficult to make the electric field intensity equal in alternating directions. 因此,要减少闪烁,把电场方向相反的象素挨着放置,由此在空间上平均象素的亮度。 Therefore, to reduce flicker, the electric field is opposite to the direction of pixels placed next, thereby spatially averaged pixel brightness. 一般地,此方法被称作“点反转”或“行反转”。 Generally, this method is called "dot inversion" or "row inversion." 可以有各种“反转驱动”法,包括逐个(逐行,逐列极性反转:1-点反转)象素上棋盘格式图案的反转、逐行反转(逐行反转:1_行反转)和每两行和每列的极性反转。 May have various "inversion drive" methods, including one at (row, column by column polarity inversion: 1-dot inversion) form a checkerboard pattern on the pixel inversion, row inversion (row inversion: 1_ line inversion), and each row and each column of the two polarity inversion. 根据需要选择其中一种。 The need to select one of them.

[0273] 如上所述,要实现高质量的显示,优选满足下列三个条件:(I)采用ac驱动,使得以特定的时间间隔如每个幀周期反转施加给每个液晶层的电场方向,(2)使交变电场方向上施加给每个液晶层的电压(或储存在液晶电容中的电荷量)与储存在存储电容中的电荷量相等,和(3)在每个垂直扫描周期(如幀周期)中将象素挨着设置成与施加到液晶层的电场方向(有时称作“电压极性”)彼此相反。 [0273] As described above, to achieve high-quality display, preferably satisfies the following three conditions: (I) use ac driving so as inverted every frame period is applied to the electric field direction of each liquid crystal layer in a specific time interval , (2) an alternating voltage is applied to the electric field direction of each of the liquid crystal layer (or the amount of charge stored in the liquid crystal capacitance) is equal to the amount of charge stored in the storage capacitor, and (3) in each vertical scanning period (e.g., frame period) is arranged in the pixel next to the electric field applied to the liquid crystal layer (sometimes referred to as "voltage polarity") opposite to each other. 顺便说一下,“垂直扫描周期”可以定义为选取扫描行后直到再选取该扫描行的周期。 Incidentally, the "vertical scanning period" may be defined as the scan line selecting period until re-select the scanning lines. 一个扫描周期等于非交错驱动情况下的一幀周期并对应于交错驱动情况下的一个场周期。 A non-interlace scanning period is equal to the driving conditions and a period corresponding to the case of interlace driving one field period. 另外,在每个垂直扫描周期中,选取一个扫描行的时刻和再选取该扫描行的时刻之差(周期)被称作水平扫描周期(IH)。 Further, in each vertical scanning period, a scanning line selection time and then select the timing at which the scanning lines (period) is referred to as a horizontal scanning period (IH).

[0274] 本发明上述实施例通过把每个象素划分为至少两个子象素并使彼此的亮度(透射率)不同而实现良好视角特性的显示。 The [0274] embodiments of the present invention, the above-described embodiment and realize good viewing angle characteristics by dividing each pixel into at least two sub-pixels and another luminance (transmittance) different. 本发明人发现,当每个象素被分成大量亮度不同的子象素时,优选除了上述三个条件外还满足关于子象素分布的第四个条件。 The present inventors have found that when each pixel is divided into a large number of different sub-pixel luminance, in addition to the above three conditions are preferably further satisfies the fourth condition concerning sub-pixel distribution. 具体地说,优选亮度不同的子象素以任何亮度的顺序随机地放置。 Specifically, the sub-pixels of different brightness is preferably randomly placed in any order of brightness. 就显示质量而言,最优选不把亮度相同的子象素放置成在行或列方向上相邻。 Terms of the display quality, most preferably not the same luminance on a subpixel placed adjacent row or column direction. 换言之,最优选亮度相同的子象素以棋盘格的图案分布。 In other words, the same luminance most preferably of sub-pixels in a checkerboard pattern distribution.

[0275] 下面将描述适合于本发明上述实施例的驱动法、象素分布和子象素分布。 [0275] The following description will be adapted to the driving method of the above-described embodiments of the invention, the distribution of sub-pixels and pixel distribution. 下面将参考图17和18描述用于根据本发明实施例的液晶显示器的驱动方法实例。 It will now be described with reference to FIGS. 17 and 18 for the driving method according to an embodiment of the present invention, examples of a liquid crystal display.

[0276] 下面的描述中引证这样的例子,象素以多行(1〜rp)和多列(1〜cq)的矩阵形式(rp, cq)分布,每个象素表示成P (p, q)(此处1≤prp以及1≤q≤cq),并且至少有两个子象素SPa(p,q)和SPb (p,q),如图17所示。 [0276] The following description of the examples of this reference, pixels in multiple rows (1~rp) and columns (1~cq) in the form of a matrix (rp, cq) distribution, each pixel is expressed as P (p, q) (where 1≤prp and 1≤q≤cq), and at least two sub-pixels SPa (p, q) and SPb (p, q), shown in Figure 17. 图17是表示一种相对分布(8行X6列)的示意图:本实施例的液晶显示器中的信号线S-CU S-C2、,S-C3、,S-C4、,…S-Ccq ;扫描线G-Ll、G-L2、G-L3、…、G-Lrp ;存储电容线CS-A和CS-B ;象素P(p,q);和组成象素的子象素SPa (p, q)和SPb (p, q)。 FIG 17 is an indication of the relative distribution (column 8 lines X6) is a schematic view: the liquid crystal display according to a signal line S-CU S-C2 present embodiment,, S-C3,, S-C4 ,, ... S-Ccq; scan lines G-Ll, G-L2, G-L3, ..., G-Lrp; storage capacitor lines CS-a and CS-B; pixel P (p, q); and sub-pixels consisting of pixels SPa ( p, q) and SPb (p, q).

[0277] 如图17所示,一个象素P (p,q)具有在扫描线G_Lp任一侧上的近似以象素为中心水平展布的子象素SPa (p, q)和SPb (p, q)。 [0277] As shown in FIG 17, one pixel P (p, q) having approximately G_Lp on either side of scanning lines in pixel central horizontal spread of sub-pixels SPa (p, q) and SPb ( p, q). 子象素SPa (p, q)和SPb (p, q)分布在每个象素的列方向上。 Sub-pixels SPa (p, q) and SPb (p, q) distributed in the column direction of each pixel. 子象素SPa(p,q)和SPb(p,q)的存储电容电极(未示出)分别连接到相邻的存储电容线CS-A和CS-B上。 Sub-pixels SPa (p, q) and SPb (p, q) of the storage capacitor electrodes (not shown) are connected to adjacent storage capacitor lines CS-A and CS-B. 根据显示的图象向象素P(p,q)供给信号电压的信号线S-Ccq在象素之间垂直分布,以向信号线右侧上的子象素的TFT元件(未示出)供给信号电压。 The vertical distribution of the image display to the signal line S-Ccq pixel P (p, q) is supplied between the pixel signal voltage to (not shown) of the TFT element sub-pixels on the right side signal line voltage supply signal. 根据图17所示的结构,一个存储电容线或一个扫描线由两个子象素共享。 According to the configuration shown in FIG. 17, a storage capacitor line or one scan line is shared by two sub-pixels. 这是增加象素开口率的益处。 This is the benefit of increasing the pixel aperture ratio.

[0278] 图18表示用于驱动具有图17所示结构的液晶显示器的各种电压(信号)的波形图。 [0278] FIG. 18 shows a driving waveform diagram of various voltages having a structure of a liquid crystal display (signal) 17 as shown in FIG. 通过用具有图18所示电压波形(a)-(j)的电压驱动具有图17所示结构的液晶显示器,可以满足上述四个条件。 Voltage (j) driving a liquid crystal display having the structure shown in FIG. 17 satisfy the above-described four conditions - a voltage waveform (a) by having 18 shown in FIG.

[0279] 接下来,将描述根据本实施例的液晶显示器如何满足上述四个条件。 [0279] Next, a liquid crystal display will be described according to the present embodiment is how to satisfy the above four conditions. 为了解释简单,假设所有的象素都以中等灰度显示。 For simplicity of explanation, it is assumed that all pixels are displayed in mid-gray.

[0280] 在图18中,波形(a)是供给信号线S_C1、S_C3、,S_C5,…(奇数信号线组有时也被称作S-ο)的显示信号电压波形(源信号电压波形);波形(b)是供给信号线S-C2、,S-C4、,S-C6,…(奇数信号线组有时也被称作SE)的显示信号电压波形;波形(c)是供给存储电容线CS-A的存储电容反电压波形;波形(d)是供给CS-B的存储电容反电压波形;波形(e)是供给扫描线G-Ll的扫描电压波形;波形(f)是供给扫描线G-L2的扫描电压波形;波形(g)是供给扫描线G-L3的扫描电压波形;波形(h)是供给扫描线G-L4的扫描电压波形;波形(i)是供给扫描线G-L5的扫描电压波形;波形(j)是供给扫描线G-L6的扫描电压波形。 [0280] In FIG. 18, waveform (a) is supplied to the signal line S_C1, S_C3,, S_C5, ... (odd signal line group is sometimes referred to as S-ο) of the display signal voltage waveforms (source signal voltage waveforms); waveform (b) is supplied to the signal lines S-C2,, S-C4,, S-C6, ... (odd signal line group is sometimes also referred to as SE) of the display signal voltage waveform; waveform (c) is supplied to the storage capacitor line the storage capacitance CS-a counter voltage waveform; waveform (d) of the storage capacitor supplying CS-B reverse voltage waveform; waveform (e) is a scan voltage waveform supplied to the scanning line G-Ll; the waveform (f) is supplied to the scan line the scanning voltage waveform of the G-L2; waveform (g) is a scan voltage waveform supplied to the scan line G-L3; and (H) is a waveform of scanning voltage waveform supplied to the scan line G-L4; waveform (i) is supplied to the scanning lines G- L5 of the scanning voltage waveform; waveform (j) is a scan voltage waveform supplied to the scan line G-L6. 扫描线电压从低水平(VgL)变为高水平(VgH)的时间与下一个扫描线电压从VgL变为VgH的时间之间的周期构成一个水平扫描周期(IH)。 The time period between the scanning line voltage from a low level (VgL) becomes a high level (VgH) and the time of the next scan line voltage changes from VgL to VgH constitutes one horizontal scanning period (IH). 扫描线的电压保持在高水平(VgH)的周期有时称作选取周期PS。 Voltage of the scanning line is kept high (VgH) is sometimes referred to as a selection period periods PS.

[0281] 因为所有象素以中等灰度显示,所以所有的显示信号电压(图18中的波形(a)和(b))具有固定振幅的振荡波形。 [0281] Since all of the pixels to mid-gray display, all the display signal voltage (waveform in FIG. 18 (a) and (b)) having a constant amplitude oscillating waveform. 另外,显示信号电压的振荡周期是两个水平扫描周期(2H)。 Further, the oscillation period of the display signal voltages is two horizontal scanning periods (2H). 显示信号电压为振荡波形以及信号线S-0(S-C1、S-C3,…)和信号线SE(S-C2、S-C4,...)的电压波形有180°像差的原因是要满足上述第三条件。 Oscillating waveform of the display signal voltage and a signal line S-0 (S-C1, S-C3, ...) and a signal line SE (S-C2, S-C4, ...) is the voltage waveform aberrations of the reasons 180 ° It is to meet the third condition. 通常在TFT驱动中,经TFT元件传输到象素电极的信号线电压受扫描电压波形的变化影响(有时称作牵引现象)。 Typically in TFT driving, the transfer element to the TFT via the signal line voltage of the pixel electrode is influenced by changes in scan voltage waveforms (sometimes called a drawing phenomenon). 考虑到牵引现象,信号线电压波形传递到象素电极之后,反电压近乎位于信号线电压波形的中心。 Taking into account the pull-in phenomenon, the signal line voltage waveform is transmitted to the pixel electrode, located near the center of the counter voltage signal line voltage waveform. 在图18中,象素电极电压波形高于反电压之处,信号电压用“ + ”号表示,象素电极电压波形低于反电压之处,信号电压用号表示。 In FIG. 18, the pixel electrode voltage waveform is higher than counter voltage, the signal voltage with a "+" sign indicates, the pixel electrode voltage waveform is lower than counter voltage, the signal voltage is indicated by numbers. “ + ”和号对应于施加到液晶层的电场方向。 "+" And the number corresponding to the direction of the electric field applied to the liquid crystal layer. 电场方向在“ + ”号和号时相反。 In the "+" opposite number and number when the electric field direction.

[0282] 如参见图12〜15所述,当扫描线的扫描电压为VgH时,连接到扫描线上的TFT导通,致使显示信号电压供给连接于TFT的子象素。 [0282] Referring to FIG 12~15 as described, when the scan voltage of the scan line is VgH, the TFT connected to the scan line is turned on, causes the display signal voltage is supplied to the sub-pixels connected to the TFT. 然后,当扫描线的扫描电压变为VgL时,存储电容反电压改变。 Then, when the scan voltage of the scan line becomes VgL, the storage capacitor counter voltage changes. 因为存储电容反电压的变化(包括方向和符号的改变)在两个子象素之间不同,因此方均根电压被施加到子象素。 Because the storage capacitor counter voltage changes (including changes of direction and the sign) differ between the two sub-pixels, so the root-mean-square voltage is applied to the sub-pixels. [0283] 在图18所示的实例中,存储电容反电压的振荡振幅和周期(波形(C)和(d))在存储电容线CS-A和CS-B之间取相同值;例如,分别是二倍的Vad(见图14)和1H。 [0283] example, the storage capacitor counter voltage of the oscillation amplitude and period (waveform (C) and (d)) take the same values ​​between the storage capacitor lines CS-A and CS-B shown in FIG. 18; e.g., Vad is twice respectively (see FIG. 14), and 1H. 另外,如果其中一个相移为180°,则CS-A和CS-B的振荡波形将重叠。 Further, if one of the phase shift is 180 °, the CS-A and CS-B oscillating waveform will overlap. 即,它们的相位差为0.5H。 That is, the phase difference thereof is 0.5H. 如果对应扫描线的电压从VgH变为VgL之后对应存储电容线的第一电压变化增大,每个子象素的平均电压则高于存在于对应扫描线处于VgH态时的周期中的对应信号线的显示信号电压,但如果对应存储电容线的第一电压变化减小,则低于存在于对应扫描线处于VgH态的周期中的对应信号线的显示信号电压。 Corresponding to the storage capacitor line after the voltage corresponding to the scan line if from VgH into VgL voltage change of the first increase, the average voltage of each sub-pixel is higher than that present in the corresponding period of the scan line is in VgH state when a corresponding signal line the display signal voltage, but if the corresponding first storage capacitor line voltage variation is reduced lower than present in the corresponding scan line is in VgH state in the display period corresponding to the signal line a signal voltage.

[0284] 因此,如果图18中所示的显示信号电压(波形(a)或(b))用“ + ”号标注,则当存储电容线的电压变化处于比下降状态高时施加到液晶层的方均根电压就较高。 [0284] Accordingly, if the display signal voltage shown in FIG. 18 (waveform (a) or (b)) with a "+" label, is applied to the liquid crystal layer when a voltage change of the storage capacitor line is in a high state decreased rms voltage is higher. 另一方面,如果图18中所示的显示信号电压(波形(a)或(b))用号标注,则当存储电容线的电压变化处于比下降状态高时施加到液晶层的方均根电压就较低。 On the other hand, if the display signal voltage 18 shown in (a waveform (a) or (b)) with the numbering, is applied to the liquid crystal layer when a voltage change of the storage capacitor line is higher than the rms voltage drop state on low.

[0285] 图17表示垂直扫描周期(在此实例中为幀周期)中象素P(p,q)和子象素SPa(p,q)和SPb (p,q)的状态。 [0285] FIG 17 shows a vertical scanning period (in this example the frame period) of the pixels P (p, q) and sub-pixels SPa (p, q) and SPb (p, q) state. 下面相对于每个子象素的扫描线对称的三个符号表示子象素的状态。 Below with respect to the scanning lines of each sub-pixel symmetry three symbols represent the state of sub-pixels.

[0286] 第一符号H或L表不施加到子象素的方均根电压的大小关系,符号H表不施加的方均根电压很高,符号L表不施加的方均根电压很低。 [0286] The first symbol H or L tables are not applied to the subpixel root mean square of the magnitude relationship between the voltage, applied to the symbol table is not H root mean square voltage is high, the symbol L represents the root mean square is not applied voltage is low. 第二符号“ + ”和表不反电极和子象素电极之间的电压大小关系,换言之,其表示施加到液晶层的电场方向。 The second symbol "+" and not the table counter voltage magnitude relation between the electrode and the subpixel electrodes, in other words, which represents the direction of electric field applied to the liquid crystal layer. 符号“ + ”表示子象素电极的电压高于反电极的电压,符号表示子象素电极的电压低于反电极的电压。 Symbol "+" represents the sub-pixel electrode voltage higher than the voltage of the counter electrode, reference numeral denotes a voltage lower than the voltage of the sub-pixel electrode of the counter electrode. 第三符号A或B表示适当的存储电容线是CS-A或CS-B。 The third symbol A or B represents an appropriate storage capacitor line is CS-A or CS-B.

[0287] 例如,来看象素P(l,I)的子象素SPa(l,l)和SPb(l,l)的状态。 [0287] For example, look at the pixel P (l, I) the sub-pixels SPa (l, l) and SPb (l, l) state. 从图18所示的波形(a)〜(e)看到,在选择GL-1的周期(扫描电压为VgH的周期PS)中,显示信号电压为“ + ”。 Waveform (a) shown in FIG. 18 ~ (e) see, GL-1 in the selection period (scan voltage is VgH period PS), the display signal voltage is "+." 当GL-1的扫描电压从VgH变为VgL时,各个子象素的存储电容线的电压(波形(c)和(d))处于图18所示箭头(从左的第一箭头)表示的状态。 When the scan voltage of GL-1 changes from VgH into VgL, the voltage (waveform (c) and (d)) of the storage capacitor lines of respective sub-pixels as shown in an arrow in FIG. 18 (the first arrows from the left) represented by status. 因而,在GL-1的扫描电压从VgH变为VgL之后,SPa(Ll)的存储电容反电压的第一电压变化为图18所示的增大(用波形(c)中的“U”表示)。 Thus, after the scan voltage of GL-1 changes from VgH into VgL, the first voltage change SPa (Ll) of the storage capacitor counter voltage is increased as shown in FIG. 18 (indicated by waveform (c) in a "U" ). 另一方面,GL-1的扫描电压从VgH变为VgL之后,SPa(Ll)的存储电容反电压的第一电压变化为图18所示的减小(用波形(d)中的“D”表示)。 On the other hand, after the scan voltage of GL-1 changes from VgH into VgL, SPa (Ll) of the first voltage change of the storage capacitor counter voltage is reduced as shown in FIG. 18 (waveform (d), a "D" representation). 因此,SPa(Ll)的方均根电压增大,而SPb (1,I)的方均根电压减小。 Thus, SPa (Ll) root mean square voltage is increased, and SPb (1, I) is the root mean square voltage is reduced. 所以,施加的SPa(l,I)的方均根电压高于SPb (I,I)的方均根电压,并且符号H贴到SPa (I,I),符号L贴到SPb (I,I)。 Therefore, SPa (l, I) square applied root mean voltages higher than SPb (I, I) is the rms voltage, and the symbol H attached to SPa (I, I), symbol L attached to SPb (I, I).

[0288] 根据图18所示的波形(b),在选择GL-1的周期中,用于P(l,l)的SPa(l,l)和SPb(Ll)的显示信号电压为当GL-1的扫描电压从VgH变为VgL时,各个子象素的存储电容线的电压(波形(c)和(d))处于图18中箭头(左边的第一箭头)所示的状态。 [0288] The waveform (b) shown in FIG. 18, in the selection period of GL-1, for P (l, l) of SPa (l, l) and SPb (Ll) when the display signal voltage of GL -1 when scan voltage from VgH into VgL, the voltage (waveform (c) and (d)) of the storage capacitor lines of respective sub-pixels in an arrow (first arrow to the left) state shown in FIG 18. 因而,在GL-1的扫描电压从VgH变为VgL之后,SPa(l,2)的存储电容反电压的第一电压变化增大(“U”),如图18所示。 Thus, after the scan voltage of GL-1 changes from VgH into VgL, SPa (l, 2) a first storage capacitor counter voltage of the voltage change is increased ( "U"), as shown in FIG. 另一方面,GL-1的扫描电压从VgH变为VgL之后,SPb(l,2)的存储电容反电压的第一电压变化减小(“D”),如图18所示。 On the other hand, after the scan voltage of GL-1 changes from VgH into VgL, SPb (l, 2) a first storage capacitor counter voltage of the voltage variation is reduced ( "D"), as shown in FIG. 因此,SPa(l, 2)的方均根电压减小而SPb(l,2)的方均根电压增加。 Thus, SPa (l, 2) root mean square voltage decreases SPb (l, 2) the root mean square voltage is increased. 所以,施加的SPa(1,2)的方均根电压高于SPb (I,2)的方均根电压,并且符号L贴到SPa(l, 2),符号H贴到SPb (1,2) 0 Therefore, SPa (1,2) of the root mean square of applied voltage is higher than SPb (I, 2) root mean square voltage, and the symbol L attached to SPa (l, 2), symbol H attached to SPb (1,2) 0

[0289] 根据图18所示的波形(a),在选择GL-2的周期中,用于P(2,l)的S批a(2,l)和S批b(2,l)的显示信号电压为当GL-2的扫描电压从VgH变为VgL时,各个子象素的存储电容线的电压(波形(c)和(d))处于图18中箭头(左边的第二箭头)所示的状态。 S [0289] The waveform (a) shown in FIG. 18, the selection period of GL-2 for the P (2, l) batch a (2, l) and the batch S b (2, l) of when the display signal voltage to a scan voltage of GL-2 changes from VgH into VgL, the storage capacitor line voltage of the respective sub-pixels (waveforms (c) and (d)) in the (second arrow on the left) indicated by arrow 18 in FIG. state shown. 因而,在GL-2的扫描电压从VgH变为VgL之后,SPa(2,I)的存储电容反电压的第一电压变化减小(“D”),如图18D所示。 Thus, after the scan voltage of GL-2 changes from VgH into VgL, SPa (2, I) a first storage capacitor counter voltage of the voltage variation is reduced ( "D"), as shown in FIG 18D. 另一方面,GL-2的扫描电压从VgH变为VgL之后,SPb (2,I)的存储电容反电压的第一电压变化增大(“D”),如图18C所示。 On the other hand, after the scan voltage of GL-2 changes from VgH into VgL, SPb (2, I) a first storage capacitor counter voltage of the voltage change is increased ( "D"), shown in Figure 18C. 因此,SPa(2,l)的方均根电压增大而SPb (2,I)的方均根电压减小。 Thus, SPa (2, l) root mean square voltage increases and SPb (2, I) is the root mean square voltage is reduced. 所以,施加的SPa(2,l)的方均根电压高于SPb (2,1)的方均根电压,并且符号H贴到SPa(2,l),符号L贴到SPb(2,l)。 Therefore, SPa (2, l) the root mean square of applied voltage is higher than SPb (2,1) root mean square voltage, and the symbol H attached to SPa (2, l), symbol L attached to SPb (2, l). 图17所示的状态以这种方式出现。 State shown in FIG 17 occurs in this manner.

[0290] 根据本实施例的液晶显示器可以以这种满足第一条件的方式驱动。 [0290] The liquid crystal display driver of the present embodiment may in this first condition is satisfied.

[0291] 因为图17和18表示幀周期中的状态,所以不可能从图中评估第一条件是否满足。 [0291] Since FIGS. 18 and 17 shows the state of the frame period, it is impossible to assess a first condition is satisfied from the drawing. 但是,通过逐幀移动每条信号线(S-0(图18A)或SE(图18B))上电压波形的相位180°,可以执行ac驱动,其中施加到每个液晶层的电场方向每个幀周期反转。 However, ((FIG. 18B) S-0 (FIG. 18A) or SE) of the voltage waveform on the phase 180 °, may be performed ac driving wherein an electric field is applied to the moving direction of each of the signal frame by frame lines of each of the liquid crystal layer in each reverse frame period.

[0292] 另外,在根据本实施例的液晶显示器中,为了防止象素的子象素的幅值关系即显示屏中子象素的亮度次序(图17中的相对位置“H”和“L”)逐幀变化,存储电容线CS-A和CS-B上电压波形的相位在信号线上的电压波形改变时改变180°。 [0292] Further, in the liquid crystal display of the present embodiment, in order to prevent the magnitude relationship of the sub-pixels, i.e. pixel position in the display luminance relative order of the neutron pixels (FIG. 17 "H" and "L ") changes from frame to frame, the phase of the storage capacitor lines CS-a and CS-B on the voltage waveform changes at 180 ° line voltage waveform signal changes. 因此,适于图17中的符号“ + ”和在下一幀中反转(例如(+,H) (-,H),和(+,L) (_,L))。 Thus, in FIG. 17 adapted symbols "+" and inverted in the next frame (e.g., (+, H) (-, H), and (+, L) (_, L)). 上述第一条件可以以此方式满足。 In this manner the above-mentioned first condition can be satisfied.

[0293] 下面我们将检查是否满足第二条件,即每个子象素的液晶层(子象素的存储电容)在不同的场方向充电到相同水平。 [0293] Now we will check whether the second condition is met, i.e., the liquid crystal layer of each sub-pixel (sub-pixel storage capacitor) charged in different directions to the same level field. 在根据本实施例的液晶显示器中,不同的方均根电压施加到每个象素中的子象素的液晶层,显示质量例如闪烁受亮度很高的子象素、即图17中符号“H”表示的子象素的决定性影响。 In the liquid crystal display of the present embodiment, different root mean square voltage is applied to the liquid crystal layer of the sub-pixels in each pixel, display quality such as flashing by high luminance subpixel, i.e., FIG. 17 symbol "H" decisive influence sub-pixel representation. 因而,第二条件尤其影响符号“H”表示的子象素。 Thus, the second sub-pixels conditions particularly affecting the symbol "H" representation.

[0294] 下面将参考图18所示的电压波形描述第二条件。 [0294] Next, the voltage waveform shown in FIG. 18 is described with reference to a second condition.

[0295] 在对应扫描线的电压为VgH的周期(选择周期PS)中对子象素的液晶电容和存储电容充电。 [0295] In the voltage corresponding to the scanning line period is VgH (selection period PS) of the liquid crystal capacitor and the storage capacitor is charged in sub-pixels. 储存在液晶电容中的电荷量依赖于选择周期中信号线的显示信号电压和反电压(图18中未示出)之间的电压差,而储存在存储电容上的电荷量依赖于选择周期中信号线的显示信号电压与存储电容线的电压(存储电容反电压)之间的电压差。 The voltage difference between the amount of charge stored in the liquid crystal capacitor depends on the signal line selection period of the display signal voltage and the counter voltage (not shown in FIG. 18) between, and the amount of charge stored in the storage capacitor depends on the selection period a voltage difference between the voltages (storage capacitor counter voltage) the display signal voltage and storage capacitor line signal line.

[0296] 如图18所示,每个选择周期中的显示信号电压可以是图中“ + ”或号表示的两类中的一种。 [0296] As shown in FIG 18, the display signal voltage in each selection period may be a figure, "+" or one of the two numbers represented. 在任一种情况下,每个选择周期中电压没有变化。 In either case, the voltage in each selection period does not change. 无论反电压(未示出)怎样,对所有的子象素都施加不随时间改变的相同DC电压。 Whether the counter voltage (not shown) how, for all the sub-pixels have the same DC voltage is applied to change over time.

[0297] 有两类存储电容线CS-A和CS-B。 [0297] There are two types of storage capacitor lines CS-A and CS-B. CS-A的电压波形在任何扫描线的选择周期中都相同。 CS-A voltage waveform is the same in the selection period of any scan line. 类似的,CS-B的电压波形在任何扫描线的选择周期中都相同。 Similarly, the voltage waveform of CS-B is the same in the selection period of any scan line. 换言之,存储电容线的电压的DC成分(DC水平)在任何扫描线的选择周期中取相同值。 In other words, DC component of the voltage of the storage capacitor line (DC level) takes the same value in the selection period of any scan line.

[0298] 因而,可以通过调节以下电压的DC成分(DC水平)来满足第二条件:每个扫描线的显示信号电压、反电极的电压、和每个存储电容线的电压。 [0298] Thus, the second condition can be satisfied by adjusting the voltage of the DC component (DC level): the display signal voltage of each scan line, voltage of the counter electrode, and the voltage of each storage capacitor line.

[0299] 接下来,我们将证实第三条件是否被满足,即场方向相反的象素是否在每帧周期中被放置成挨在一起。 [0299] Next, we will verify whether the third condition is satisfied, i.e., whether the field direction opposite to the pixel is placed next to each other in each frame period. 在根据本实施例的液晶显示器中,不同的方均根电压施加到每个象素中子象素的液晶层,第三条件应用到被提供相同方均根电压的子象素与象素之间的关系。 In the liquid crystal display of the present embodiment, different root mean square voltage is applied to the liquid crystal layer of each pixel neutron pixel, the third condition is applied to provide the same relationship between the root mean square sub-pixels of the pixel voltage. 尤其重要的是,第三条件通过高亮度的子象素、即图1 7中符号“H”表示的子象素得到满足,如同第二条件的情形。 It is particularly important, the sub-pixel in the third condition represented by the high luminance sub-pixels, i.e., 17 in FIG symbol "H" is met, the second condition as a case.

[0300] 如图17所示,表示每个象素极性(电场方向)的“ + ”和在行方向(水平方向)每两个象素(两列)转变一次,如(+,_)、(+,_)、(+,_),在列方向(竖直方向)每两个象素(两行)转变一次,如(+,-)、(+,-)、(+,-)、(+,-)。 [0300] As shown in FIG 17, each pixel represents a polarity (electric field direction) of the "+" and the row direction (horizontal direction) every two pixels (two columns) a transition, such as (+, _) , (+, _), (+, _), (two rows) into every two pixels in the column direction (vertical direction) once, such as (+, -), (+, -), (+, - ), (+, -). 依逐个象素看,表现出点反转,满足第三条件。 According to pixel by pixel watch, showing dot inversion, satisfy the third condition.

[0301] 接下来,我们来看高亮度的子象素,即图17中符号“H”表示的子象素。 [0301] Next, we look at the sub-pixel high-brightness sub-pixels, i.e., FIG. 17 symbols "H" representation.

[0302] 参见图17,在图中所示的行方向不存在极性反转,例如在第一行上关于子象素SPa的+H、+H、+H,但在图中所示的列方向每两个象素(两行)极性转变一次,如第一列中的(+H,-H)、(+H,-H)、(+H,-H)、(+H,-H)。 [0302] Referring to Figure 17, the row direction as shown in FIG polarity inversion does not exist, for example, on the first line on the subpixel SPa + H, + H, + H, but as shown in FIG. column direction every two pixels (two rows) of polarity inversion time, as in the first column (+ H, -H), (+ H, -H), (+ H, -H), (+ H, -H). 已知为行反转的状态可以在尤其重要的高亮度子象素的水平处观察到,这意味着它们满足第三条件。 The state known as line inversion can be observed at the level of the particularly important sub-pixels of high brightness, which means that they satisfy the third condition. 由符号L表示的子象素也以规则的图案分布,满足第三条件。 Sub-pixels indicated by the symbol L are also distributed in a regular pattern, satisfying the third condition.

[0303] 接下来,我们将讨论第四条件。 [0303] Next, we will discuss fourth condition. 第四条件需要子象素中亮度相同的子象素不应挨着放置,这使得亮度有所变化。 The fourth condition requires the same sub-pixel luminance of sub-pixels should not be placed next, so that the luminance varies.

[0304] 根据本实施例,亮度变化的子象素、即施加到其液晶层的方均根电压不同的子象素用图17中的符号“H”或“L”表示。 [0304] "H" or "L" in FIG. 17 indicated by square symbols according to the present embodiment, the luminance change of sub-pixels, i.e., the liquid crystal layer is applied to its root mean different voltage sub-pixels.

[0305] 在图17中,如果子象素分成由行方向的两个子象素和列方向的两个子象素组成的四组(如SPa(l,l)、SPb(l,l)、SPa(I, 2)和SPb (1,2)),则整个矩阵由子象素组形成,其中H和L在上部行中从左到右分布,L和H分布在下部行中。 [0305] In FIG. 17, if the sub-pixels are divided into four groups (e.g., SPa (l, l) by the two sub-pixels in the row direction two sub column direction and composed of pixels, SPb (l, l), SPa (I, 2) and SPb (1,2)), then the entire matrix is ​​formed of a subset of pixels, where L and H in the upper row from left to right in the distribution, the distribution of H and L in a lower row. 因而,在图17中,符号“H”和“ L”在子象素水平以棋盘格图案分布,满足第四条件。 Thus, in FIG. 17, the symbol "H" and "L" level in the sub-pixel in a checkerboard pattern distribution, satisfying the fourth condition.

[0306] 来看矩阵,在象素水平,在任意行的象素情况下每个象素中子象素的亮度顺序和列方向上分布的子象素的位置之间的对应性在行方向上周期性(每个象素)地改变,但在任意列的象素的情况下恒定。 [0306] view matrix in the row direction on the correspondence between the positions of sub-pixels in the pixel levels of pixels in an arbitrary row of the luminance distribution of each pixel sequentially and pixel column direction neutron periodically (every pixel) change, but in the case of a constant pixel in any column. 因而,在任意行的象素P (P,q)中,最亮的子象素(在此实例中用“H”表示的子象素)在q为奇数时是SPa (p,q),在q为偶数时是SPb (p,q)。 Thus, any row in the pixel P (P, q), the brightest sub-pixels (sub-pixels in this example, with "H" represents a) when q is an odd number is SPa (p, q), when q is an even number is SPb (p, q). 反之,q为奇数时最亮的子象素是SPb (p,q),q为偶数时是SPa(p,q)。 Conversely, when q is an odd number of the brightest sub-pixels is SPb (p, q), when q is an even number is SPa (p, q). 另一方面,在任意列的象素P(P,q)中,最亮的子象素在同一列中总是SPa (p,q)或SPb (p,q),无论p是奇数还是偶数。 On the other hand, any column in the pixel P (P, q), the brightest sub-pixels in the same column is always SPa (p, q) or SPb (p, q), whether p is an odd or even . 此处SPa(p,q)或SPb(p,q)的交替意味着无论P是奇数还是偶数,奇数列中最亮的子象素为SPa (p,q),而无论P为奇数还是偶数,偶数行中最亮的子象素为SPb (p,q)。 Here SPa (p, q) or SPb (p, q) alternate means whether P is odd or even, odd columns of the brightest sub-pixels SPa (p, q), regardless of whether P is odd or even the even rows of the brightest sub-pixels SPb (p, q).

[0307] 如上述参考图17和18所示,根据本实施例的液晶显示器满足上述四个条件,并因而可以实现高质量的显示。 [0307] As described above with reference to FIGS. 17 and 18, the liquid crystal display according to the present embodiment satisfies the above four conditions, and thus can achieve high-quality display.

[0308] 接下来,参考图19和20描述利用对象素和子象素的不同驱动方法的另一实施例的液晶显示器。 [0308] Next, described with reference to FIGS. 19 and 20 using a liquid crystal display according to a different embodiment of a driving method of pixels and sub-pixels. 图19和20对应于图17和18。 19 and 20 correspond to FIGS. 17 and 18.

[0309] 如图20所示,在根据本实施例的液晶显示器中,显示信号电压和存储电容反电压每2H振荡一次。 [0309] shown in Figure 20, the liquid crystal display of the present embodiment, the display signal voltage and storage capacitor counter voltage oscillation every 2H. 因而振荡周期是4H(四个水平写入时间)。 Thus the oscillation period is 4H (four horizontal write times). 奇数信号线S-0(S-C1、S-C3、S-C5...)和偶数信号线SE(S-C2、S-C4、S-C6...)的信号电压的振荡相位差为180度(以时间来说为2H)。 Odd-phase oscillation signal lines S-0 (S-C1, S-C3, S-C5 ...) and the even-line signal SE (S-C2, S-C4, S-C6 ...) signal voltage 180 degrees (as for a time 2H). 存储电容线CS-A和CS-B的电压振荡相位差也为180度(以时间来说为2H)。 Storage capacitor lines CS-A and CS-B phase voltage oscillations are also 180 degrees (as for a time 2H). 另外,信号线的电压振荡比存储电容线CS-A的电压振荡相位滞后45度(1/8周期,即H/2)。 Further, the signal line voltage oscillation lags 45 degrees (1/8 period, i.e., H / 2) than the oscillation phase of the voltage storage capacitor line CS-A is. 顺便说一下,45度的相位差用于防止扫描线的VgH-VgL电压变化和存储电容线的电压变化重叠,并且此处采用的值不是严格要求,也可以根据需要采用其它值。 Incidentally, a phase difference of 45 degrees to prevent the VgH-VgL voltage change of the voltage change and the storage capacitor line overlaps the scan lines, and the value used here is not strictly required, other values ​​may be employed as desired.

[0310] 对于根据本实施例的液晶显示器,每个象素由两个亮度变化且由“H”或“L”表示的子象素组成。 [0310] For the sub-pixel liquid crystal display according to the present embodiment, each pixel is composed of two luminance variation and a "H" or "L" indicates a composition. 另外,如图19所示,由符号“H”或“L”表示的子象素以棋盘格图案分布,这意味着满足第四条件,与上面的实施例一样。 Further, as shown in FIG. 19, a sub-pixel by the symbol "H" or "L" indicates the distribution in a checkerboard pattern, which means that satisfies a fourth condition, as in the above embodiments. 关于第一条件,可以利用与上述图17和18所示实施例中采用一样的反转法满足。 Regarding the first condition, it may be utilized as shown in FIGS. 17 and 18 of the above-described embodiment employed the same inversion method satisfied. [0311] 但是,图19和20所示的实施例不能满足上述第二条件。 [0311] However, the embodiment shown in FIGS. 19 and 20 can not satisfy the second condition.

[0312] 现在来看图19中第一列的第一至第四行所示象素P(l,I)、P(2,I)、P(3,I)和P(4,I)的较亮子象素Pa(l,I)、Pa (2,I)、Pa (3,I)和Pa (4,I)。 [0312] Referring now to the pixel shown in FIG. 19 of the first to fourth row and first column of P (l, I), P (2, I), P (3, I), and P (4, I) brighter sub-pixels Pa (l, I), Pa (2, I), Pa (3, I) and Pa (4, I). 当Pa(l,l)被充电时,即当选择G-Ll时,对应信号线的极性符号为“ + ”。 When Pa (l, l) is charged, i.e., when the selected G-Ll, the corresponding signal line polarity sign is "+." 当Pa(3,l)被充电时,即当选择G-L3时,对应信号线的极性符号为另外,当Pa(l,l)被充电时,即当选择G-Ll时,对应存储电容线CS-A的电压波形在接近选择周期的中心处开始阶梯式下降。 When Pa (3, l) is charged, i.e., when the selected G-L3, polarity sign corresponding to the signal line to another, when Pa (l, l) is charged, i.e., when the selected G-Ll, the corresponding storage voltage waveform of the capacitor line CS-a begins a step down near the center of the selection period. 当Pa(3,I)被充电时,即当选择G-L3时,对应存储电容线CS-A的电压波形在接近选择周期的中心处开始阶梯式上升。 When Pa (3, I) is charged, i.e., when the selected G-L3, corresponding to the storage capacitor lines CS-A voltage waveform starting a step up near the center of the selection period. 因而,通过精确控制存储电容线CS-B和扫描线的信号电压波形的相位,可以使存储电容反电极在Pa(l,l)被充电以及Pa(3,I)被充电时具有相同的DC水平。 Accordingly, the phase of the signal voltage waveforms accurately control the storage capacitor line CS-B and scan line, can cause the storage capacitor counter electrode is charged Pa (l, l) and Pa (3, I) is the same for DC charging Level. 通过将DV水平设置至Ij Pa (I,I)被充电时存储电容反电极的电压(等于子象素电极的电压)与Pa (3,I)被充电时存储电容反电极的电压(等于子象素电极的电压)的平均值,可以使储存在Pa(l,I)和Pa(3,I)中的电荷量相等。 Voltage of the storage capacitor counter electrode when charged with Pa (3, I) provided by the DV level to Ij Pa (I, I) the voltage of the storage capacitor is charged when the counter electrode (equal to the voltage of the sub-pixel electrodes) (equal sub voltage of the pixel electrode) of the average amount of charge can be stored in Pa (l, I), and Pa (3, I) are equal. 接下来来看在Pa(2,I)处,在对应的周期中,即在选择G-L2时,对应信号线的极性符号为(与上述Pa(3,I)的情形相同),对应存储电容线的电压取固定值(不是象上述一样的振荡波形)。 Next, in view of polarity sign Pa (2, I) at the corresponding period, i.e., when selecting G-L2, corresponding to the signal lines is (above Pa (3, I) is the same case), corresponding to voltage storage capacitor line takes a fixed value (not the same as the above-described oscillation waveform). 因而,通过使对应于Pa(2,I)的存储电容线的电压值与上述的DC水平关于Pa(l,I)及Pa(3,I)相同,可以使储存在Pa(1,I)、Pa(2,I)及Pa(3,I)中的电荷量相同。 Accordingly, the voltage value and the DC-level corresponding to Pa (2, I) of the storage capacitor line on Pa (l, I) and Pa (3, I) the same, can be stored in Pa (1, I) , the same amount of charge Pa (2, I) and Pa (3, I) is. 但是,由于下列原因,不可能使储存在Pa(4,I)中的电荷量与储存在Pa(l,l)、Pa(2,l)及Pa(3,l)中的电荷量相同。 However, for the following reasons, it is impossible that the amount of charge stored in Pa (4, I) and the amount of charge stored in Pa (l, l), Pa (2, l) and Pa (3, l) is the same. Pa(4,l)的信号线的极性符号与Pa(l,I)的相同,无论什么时刻,对应存储电容线的电压取固定值(不是如上所述的振荡波形)。 The same polarity sign Pa (4, l) and the signal line Pa (l, I), no matter what time, a voltage corresponding to the storage capacitor line takes a fixed value (not an oscillating waveform as described above). 因此,需要使Pa(4,I)的存储电容线的电压值(上述固定值)与DC水平关于Pa(l,l)及Pa(3,I)相同,与Pa(2,l)的情形相同,即等于Pa(4,I)以及对于Pa(2,l)的存储电容线的电压值(上述固定值)。 Accordingly, it is necessary to Pa (4, I) a voltage value (the fixed value) and the DC level of the storage capacitor line on Pa (l, l) and Pa (3, I) the same, in the case of Pa (2, l) of identical, i.e. equal to Pa (4, I) and for Pa (2, l) a storage capacitor line voltage value (the fixed value). 但是,这是不可能的,因为从图19和20中可以看出,对于Pa (2,I)及Pa (4,I)的存储电容线为CS-B,他们有规律的振荡波形,在Pa(2,I)的选择周期中选择振荡波形的最大值,而在Pa(4,I)的选择周期中选择振荡波形的最小值,使得两个电压必然不同。 However, this is not possible, as can be seen from FIGS. 19 and 20, for Pa (2, I) and Pa (4, I) is a storage capacitor line CS-B, their regular oscillation waveform, in Pa (2, I) in the selection period to select the maximum value of the oscillation waveform, the minimum value of the oscillation waveform is selected in the selection period Pa (4, I) is such that the two voltages necessarily different.

[0313] 另外,就分布相同极性的子象素以使其尽可能地不彼此相邻的第三条件而言,本实施例劣于图17和18所示的上述实施例。 [0313] Further, on the distribution of sub-pixels of the same polarity so that it is not possible in terms of the third condition adjacent to each other, inferior to the above-mentioned embodiments shown in FIGS. 17 and 18 of the present embodiment.

[0314] 参见图19,我们来看有较大电压施加到其液晶层的组成象素的子象素、即符号H表示的子象素的极性反转。 [0314] Referring to Figure 19, we have a look at a larger voltage is applied to the picture elements of a liquid crystal layer of the pixels, i.e., sub-pixels indicated by the symbol H polarity inversion. 在图19中,在图中所示的行方向不存在极性反转,如第一行中对于子象素SPa的+H、+H、+H(如同图17),但在图中所示的列方向每四个象素极性反转,如第一列中的(+H,-H,-H,+H)、(+H,-H,-H,+H)。 In Figure 19, the row direction as shown in FIG polarity inversion does not exist, as in the first row to the sub-pixels SPa + H, + H, + H (as in FIG. 17), but as in FIG. column direction every four pixels illustrated in the polarity inversion, as in the first column (+ H, -H, -H, + H), (+ H, -H, -H, + H). 在参见图17和18所述的实施例中,每两个象素发生一次极性反转,本实施例的极性反转周期为1/2。 In Example 17 and Figure 18, every two pixels occur once polarity inversion, a polarity inversion cycle of this embodiment is 1/2. 换言之,在参见图17和18所述的实施例中,极性反转频率是以上参见图19和20所述实施例的两倍。 In other words, in the embodiment and the Figure 18, 17, the polarity inversion frequency is twice as above with reference to FIGS. 19 and 20 of the embodiment. 在这一方面,本实施例(参见图19和20所述)劣于参见图17和18所述的实施例。 In this respect, the present embodiment (see FIG. 19 and the 20) and is inferior to the see Example 17 18 FIG.

[0315] 显示质量实际上在实施图17所示象素分布的前一实施例的驱动方法与本实施例的驱动方法之间进行比较,并在显示质量中看出差别。 [0315] Display quality actually compared between the drive method of the previous embodiment of the driving method of the embodiment shown in FIG pixel distribution 17 of the present embodiment, and a display to see the difference in quality. 具体地说,例如当用固定的视线观察64/255灰度显示时,两种驱动方法看不出有明显的差异,其中这种灰度在用于改变亮度的子象素中产生较大的亮度差异。 Specifically, for example when the observation 64/255 gradation display with a fixed line of sight, two drive methods do not see a significant difference, where such a greater gradation is required in subpixel for changing luminance in differences in brightness. 但是,当通过移动视线观察显示时,在本实施例的驱动方法中看到水平条文(图19),而前一实施例(图17)的驱动方法没有这些问题。 However, when observing the display by moving the line of sight, see horizontal section (FIG. 19) In the driving method of this embodiment, a driving method of the previous embodiment (FIG. 17) do not have these problems. 可以相信,所述的差异是由上述极性反转周期的差异所致。 It is believed that the difference is caused by the difference in the polarity inversion cycle. 因为每个象素中包含的两个子象素的亮度更显著,所以优选使较亮子象素的极性反转周期最小。 Since the luminance of two subpixels included in each pixel is more significant, it is preferable that the brighter sub-pixels minimum polarity inversion cycle. 在上述实例中每个象素被分成两个子象素,但也可以分成三个或更多个子象素,优选以这样方式分布子象素,即,使最亮子象素的极性反转周期最小。 In the above example, each pixel is divided into two sub-pixels, but may be divided into three or more sub-pixels, preferably the sub-pixels in such a distributed manner, i.e., so that the brightest sub-pixel polarity inversion cycle of a minimum. 不用说,最好其它所有的子象素都与最亮子象素有相同的极性反转周期。 Needless to say, the best of all the other sub-pixels are the brightest sub-pixels have the same polarity inversion cycle.

[0316] 接下来,参见图21A和21B对下面的实施例进行描述,该实施例中,即使通过移动视线观察到显示,利用较短极性反转周期的上述水平条文也比图17所示的实施例中更不明显。 [0316] Next, referring to FIGS. 21A and 21B of the embodiment will be described below, in the embodiment, even when the display is observed by moving the line of sight, the use of a shorter polarity inversion cycle than the horizontal provisions of the embodiment 17 shown in FIG. embodiments less noticeable.

[0317] 根据图17所示的实施例,虽然组成象素的较亮子象素(用符号“H”表示的)在(+,-)、(+,-)、(+,-)和(+,-)所不的列方向上反转,但在+,+,+,+,+,+ 或-,-,-,_ 所示的方向不反转。 [0317] According to the embodiment shown in Figure 17, although the composition of the brighter sub-pixels of the pixel (indicated by symbol "H" represents) of (+, -), (+, -), (+, -) and ( +, -) in the column direction is not reversed, but in +, +, +, +, +, + or -, -, -, _ is not inverted in the direction shown. 相反,根据图21所示的实施例,较亮子象素的“ + ”和不仅在(+,-)、(+,-)、(+,-)、(+,-)所示的列方向上反转,而且也在(+,-)、(+,-)所示的行方向上反转。 In contrast, according to the embodiment shown in FIG. 21, the brighter sub-pixels "+" and not only in the (+, -) as shown in the column direction, (+, -), (+ - -), (+) inverting, but also (+, -), (+, -) as shown in the row direction is reversed. 因而,图20所示的实施例采用了比图17所示实施例短的极性反转周期。 Thus, the embodiment shown in FIG. 20 uses a shorter polarity inversion cycle than the embodiment shown in FIG. 17 embodiment. 在此方面,图20所示的实施例更优于图17所示的实施例。 In this regard, the embodiment shown in FIG. 20 is more than 17 in the embodiment shown in FIG.

[0318] 甚至在图21所示的实施例中,在组成象素的子象素中,符号“H”表示的较亮子象素以棋盘格图案分布,满足第四条件。 Brighter sub-pixels distributed in a checkerboard pattern, satisfying the fourth condition [0318] Even in the embodiment illustrated in FIG. 21, the sub-pixels consisting of pixels, the symbol "H" representation.

[0319] 可以如下实施图21A所示的象素分布。 Pixel distribution shown in [0319] FIG embodiment may be as follows 21A.

[0320] 如图21B所示,每行中用于子象素的存储电容反电极每两列交替连接到存储电容线CS-A或CS-B上。 [0320] As shown in FIG. 21B, for each row of the storage capacitor counter electrodes of sub-pixels are alternately connected to the storage capacitor lines CS-A or CS-B every two columns. 这种结构变化可以通过比较图21所示的本实施例与图17或18所示的前述实施例清楚地看出。 The structure of this variation may be illustrated by comparing FIG. 21 or 18 shown in FIG. 17 of the embodiment examples clearly seen. 具体地说,这可以通过查看行方向子象素处选取的存储电容线看出。 Specifically, as can be seen at the line of direction sub-pixel storage capacitor lines selected by viewing. 例如,在子象素SPa(l,l)〜SPa(l,6)行中,从符号“A”或“B”表示的存储电容反电极中为SPa(l,l)选“A”,为SPa(l,2)选“B”,为SPa(l,4)和SPa(l,5)选“A”,为SPa(l,6)选“B”,如图21所示,而对图17或18中所示的所有子象素SPa (I,I)〜SPa (I,6)选“A”。 For example, the sub-pixels SPa (l, l) ~SPa (l, 6) in a row, the storage capacitor indicated by the symbol "A" or "B" is the counter electrode SPa (l, l) selected from the "A", is SPa (l, 2) selected from the "B", is SPa (l, 4) and SPa (l, 5) selected from the "A", is SPa (l, 6) is selected from "B", shown in Figure 21, and 17 or FIG. 18 to all sub-pixels shown in SPa (I, I) ~SPa (I, 6) is selected from "a".

[0321] 根据图21所示的实施例,图18中所示的电压波形(a)〜(j)可以用作供给包括存储电容线CSA和CS-B 的导线的电压波形。 [0321] According to the embodiment shown in FIG. 21, a voltage waveform (a), in 18 ~ (j) may be used as the supply conductors comprise a voltage waveform and a storage capacitor line CS-B of CSA. 但是,因为显示信号电压每两列转换一次,因此具有图18所示波形(a)的显示信号电压提供给S-C1、S-C2、S-C5、S-C6、…,如图21A所示,而具有图20所示波形(b)的显示信号电压提供给图21A中所示的S-C3、S-C4、S-C7(未示出)、S-C8(未示出)、…。 However, because the display signal voltage conversion once every two columns, thus having a display signal voltage waveforms in FIG. 18 (a) is shown to provide S-C1, S-C2, S-C5, S-C6, ..., FIG. 21A shown, while the display signal voltage has a waveform (b) shown in FIG. 20 is supplied to FIGS. 21A S-C3 shown, S-C4, S-C7 (not shown), S-C8 (not shown), ....

[0322] 尽管在上述实施例中,供给存储电容线的存储电容反电压是占空比为1:1的矩形波振荡电压,但是本发明也可以用频宽比不是1:1的矩形波。 [0322] Although in the above embodiment, the storage capacitor counter voltage supplied to the storage capacitor line is the duty ratio of 1: 1 of the rectangular wave oscillation voltage, but the present invention can also be used instead of the duty cycle 1: 1 is a rectangular wave. 除此之外,还可以用其它波形,例如正弦波或三角形波。 In addition, other waveforms may also be used, for example, a sine wave or a triangular wave. 在这种情况下,当连接到多个子像素的TFT关闭时,在供给子像素存储电容反电极的电压中产生的变化可以根据子像素来改变。 In this case, when a plurality of sub-pixels connected to the TFT-off, resulting in changes in the supply voltage of the sub-pixel storage capacitor counter electrode may be changed according to the sub-pixels. 但是,使用矩形波使存储在不同子像素(液晶电容和存储电容)的电荷数量和施加到不同子像素上的电压均方根容易相等。 However, using a rectangular wave so that the amount of charge equal rms easier different sub-pixels (liquid crystal capacitors and storage capacitors) and the voltage applied to the different sub-pixel memory.

[0323] 而且,尽管在上述参照图17和21所述的实施例中,供给存储电容线(波形(C)和(d))的振荡电压振荡周期是1H,如图18所示,但也可以是IH被自然数除所得到的IH的分数,例如1/1H,1/2H,1/3H,1/4H等。 [0323] Further, although in the embodiment described above and with reference to the figures 17 21, supplying a storage capacitor lines (waveforms (C) and (d)) is the oscillation period of the oscillating voltage 1H, as shown in Figure 18, but IH IH fraction may be obtained in addition to a natural number, for example, 1 / 1H, 1 / 2H, 1 / 3H, 1 / 4H and the like. 但是,因为振荡电压振荡周期变短,因此难以构成驱动电路或驱动电路的功耗增大。 However, since the oscillation period of the oscillating voltages becomes shorter, it is difficult to constitute a driving circuit and a drive circuit power consumption is increased.

[0324] 接下来,描述本发明第三方面的实施例。 [0324] Next, embodiments of the third aspect of the present invention.

[0325] 本发明第三方面的实施例涉及通过将每个像素分成多个不同亮度的子像素来提高视角特性、尤其是提高显示对比度的大或高分辨率液晶显示器和它的驱动方法。 Example [0325] The third aspect of the present invention relates to a sub-pixel of each pixel is divided into a plurality of different viewing angle characteristics to enhance the brightness, contrast or large high resolution liquid crystal display and its driving method in particular to improve the display. [0326] 如上所述,本发明第一方面的实施例是通过将每个像素分成多个不同亮度的子像素而提高视角特性、尤其是显示对比度的液晶显示器或驱动方法。 [0326] As described above, the present embodiment of the first aspect of the invention is achieved by each pixel is divided into a plurality of sub-pixels of different brightness to improve viewing angle characteristics, in particular, it is a liquid crystal display or the contrast ratio. 这种类型的显示和驱动这里是指多像素显示、多像素驱动、面积比灰度等级显示、或面积比灰度等级驱动。 This type of display and driving herein means a multi-pixel display, multi-pixel driving, area ratio gray scale display, or area ratio gray scale driving. 还有,本发明第二方面的实施例是具有能减小显示“闪烁”的子像素阵列的液晶显示器或它的驱动方法,并且与第一方面实施例适当地组合。 Further, the embodiment of the second aspect of the present invention can reduce the display is a liquid crystal display "flicker" or its sub-pixel driving method, and the embodiment is appropriately implemented in combination with the first aspect.

[0327] 在根据本发明第二方面实施例的液晶显示器中,施加到CS总线(存储电容线)的振荡电压(存储电容反电压)振荡周期等于或短于一个水平扫描周期。 [0327] In the liquid crystal display according to the second aspect of the embodiment of the present invention, is applied to the CS bus line (storage capacitor line) oscillating voltages (storage capacitor counter voltage) is equal to or shorter than the oscillation period of a horizontal scanning period. 如果以这种方式将短振荡周期的振荡电压施加到CS总线上,增加显示板的分辨率和尺寸,所得到的振荡电压的短振荡周期使得振荡发生器电路难(昂贵)以构建,增加功耗,或增加由CS总线电负载阻抗造成的波形钝化的影响。 In this manner, if an oscillating voltage is applied to the short oscillation cycle of the CS bus line, and increasing the size of the display panel resolution, short oscillation period of the oscillating voltage such that the resulting oscillation generator circuits difficult (expensive) to build, increase power consumption, or increase the impact of waveform rounding resulting from electrical load impedance of the CS bus line.

[0328] 与根据第二方面实施例的液晶显示器比较,描述根据本发明第三方面实施例的液晶显示器,这里再次描述根据本发明第二方面实施例的液晶显示器的具体结构和操作。 [0328] The liquid crystal display of the comparative example of the second embodiment aspect, a liquid crystal display according to a third aspect of the embodiments of the present invention, a liquid crystal display according to the specific configuration and operation of the embodiment of the second aspect of the present invention described herein again. 下面是通过将CS总线振荡电压的振荡周期设定为一个水平扫描周期来实现上述面积比灰度等级的示例。 The following is an example to realize the above-described area ratio gray scale by the oscillation period of the oscillating voltage bus line CS is set to one horizontal scanning period. 参照附图,集中描述下列三点。 Referring to the drawings, the following description of three concentrated. 第一点涉及液晶显示器的结构,围绕连接子像素的存储电容的存储电容反电极和CS总线之间的连接图案定中心。 The first point relates to the structure of a liquid crystal display, centering connection patterns between the storage capacitor is connected around the storage capacitor counter electrodes of sub-pixels and CS bus line. 第二点涉及根据栅极总线电压波形的CS总线振荡周期和相位。 The second point relates to the oscillation period of CS bus line and the gate bus phase voltage waveform. 第三点涉及子像素的驱动和显示状态。 The third point concerns driving and display sub-pixel state.

[0329] 图22是具有图17所示像素阵列的液晶显示器的一定区域的等效电路图。 [0329] FIG. 22 is an equivalent circuit diagram of a certain area of ​​a liquid crystal display shown in FIG. 17 pixel array. 液晶显示器具有行和列排列成矩阵的像素。 The liquid crystal display having pixels arranged in a matrix of rows and columns. 每个像素具有两个子像素(用符号A和B表示)。 Each pixel has two sub-pixels (indicated by symbol A and B). 每个子像素包括液晶电容CLCA_n,m或CLCB_n,m和存储电容CCSA_n,m或CCSB_n,m。 Each sub-pixel includes a liquid crystal capacitor CLCA_n, m or CLCB_n, m and the storage capacitor CCSA_n, m or CCSB_n, m. 每个液晶电容由子像素电极、反电极ComLC、和夹在它们之间的液晶层组成。 Each liquid crystal capacitance formed by the sub-pixel electrode, counter electrode COMLC, and sandwiched therebetween the liquid crystal layer. 每个存储电容由存储电容电极、绝缘膜和存储电容反电极(ComCSA_n或ComCSB_n)组成。 Each storage capacitor counter electrodes of the storage capacitor electrode, an insulating film and a storage capacitor (ComCSA_n or ComCSB_n) composition. 两个子像素经过各个TFTA_n,m和TFTB_n,m连接到公共信号线(电源总线)SBL_m上。 After two sub-pixels each TFTA_n, m and TFTB_n, m is connected to the common signal line (power bus) SBL_m. 通过施加到公共扫描线(栅极总线)GBL_n上的扫描信号电压来开启和关闭TFTA_n,m和TFTB_n,m。 To open and close TFTA_n, m and TFTB_n, m by applying to the common scanning line (gate bus line) in the scanning signal voltage GBL_n. 当两个TFT开启时,显示器信号电压经过公共信号线供给各个子像素电极和两个子像素的存储电容电极。 When two TFT is turned on, a display signal voltage supplied through the common signal line electrode of the storage capacitor and the respective sub-pixel electrodes of two sub-pixels. 经过CS总线(CSBL),两个子像素电极之一的存储电容反电极连接到存储电容干线(CS干线)CSVtypeRl上,其它子像素的存储电容反电极连接到存储电容干线(CS干线)CSVtypeR2 上。 After CS bus (CSBL), the storage capacitor of one of the two subpixel electrodes connected to the counter electrode storage capacitor trunk (CS trunk) CSVtypeRl, other sub-pixel storage capacitor counter electrodes connected to a storage capacitor trunk (CS trunk) CSVtypeR2.

[0330] 应该注意在图22列方向相邻像素的子像素共享电公共CS总线。 [0330] It should be noted that the sub-pixels adjacent pixels share a common electrical bus CS direction in FIG. 22. 特别是用于η行中具有CLCB_n,m的子像素的CS总线CSBL和用于列方向相邻行中具有CLCA_n+l,m象素的子像素的CS总线CSBL电共用。 Particularly for η row having CLCB_n, m sub-pixels and CS bus line CSBL for adjacent rows having the column direction CLCA_n + l, CS bus line CSBL electrically common sub-pixels of the pixel m.

[0331] 图23A和23B示出就栅极总线的电压波形和所示子像素电极电压而言供给CS总线的振荡电压的振荡周期和相位。 [0331] FIGS. 23A and 23B show the oscillation period of the supply voltage and the phase of the oscillation of the CS voltage waveform on the bus line and the gate bus line shown in the sub-pixel electrodes in terms of voltage. 液晶显示器通常反转(以规定时间间隔)施加到每个像素液晶层的电场方向,因此,需要考虑对应电场方向的两个类型驱动电压波形。 The liquid crystal display typically inversion (at predetermined intervals) the direction of the electric field applied to each pixel of the liquid crystal layer, therefore, we need to consider two types of the electric field corresponding to the direction of driving voltage waveforms. 在图23A和图23B中分别示出两种类型的驱动状态。 Illustrate two types of driving state in FIG. 23A and FIG. 23B.

[0332] 在图23A和23B中,VSBL_m表示供给m列电源总线SBL_m的显示信号电压(电源信号电压)的波形,同时VGBL_n表不供给η列的栅极总线GBL_n的扫描信号电压(栅极信号电压)的波形。 [0332] In FIGS. 23A and 23B, VSBL_m m column represents the display signal voltage supplied to the power bus SBL_m (power supply voltage signal) waveform, while VGBL_n table is not supplied scanning signal voltage of the gate bus GBL_n η column (gate signal voltage) waveform. VCSVtypeRl和VCSVtypeR2分别表示供给CS干线CSVtypeRl和CSVtypeR2的振荡电压的波形,作为存储电容反电压。 VCSVtypeRl and VCSVtypeR2 shows waveforms of oscillating voltage supplied to the CS trunk CSVtypeRl CSVtypeR2 and, as the storage capacitor counter voltage. VPEA_m,η和VPEB_m,η表示各个子像素液晶电容的电压波形。 VPEA_m, η and VPEB_m, η represents the voltage waveform of each sub-pixel of the liquid crystal capacitor. [0333] 在图23A和23B中注意的第一点是CSVtypeRl和CSVtypeR2的电压VCSVtypeRl和VCSVtypeR2的振荡周期都等于一个水平扫描周期(IH)。 [0333] FIGS. 23A and 23B in the first point and CSVtypeR2 noted CSVtypeRl VCSVtypeRl voltage and the oscillation period VCSVtypeR2 are equal to one horizontal scanning period (IH).

[0334] 在图23A和23B中注意的第二点是VCSVtypeRl和VCSVtypeR2的相位如下。 [0334] FIGS. 23A and 23B in the second phase point is noted and VCSVtypeR2 VCSVtypeRl follows. 首先,观察CS干线之间的相位差,VCSVtypeR2落后VCSVtypeRl为0.5H。 First, observe the phase difference between the CS trunk, VCSVtypeR2 behind VCSVtypeRl to 0.5H. 接下来,观察CS干线和栅极总线的电压,CS干线和栅极总线的电压相位如下。 Next, observation of the CS trunks and gate bus lines, CS main lines and the voltage phase gate bus follows. 从图23A和23B中可以看出,对应各个CS干线的栅极总线电压从VgH变为VgL的时间与CS干线电压的平坦部分到达它们的中心的时间一致。 As it can be seen from FIGS. 23A and 23B, the time gate corresponding to respective CS trunks bus voltage from VgH to VgL to the planar portion of the CS trunk voltages reach their centers of time consistent. 换句话说,在图23A和23B中的Td值是0.25H。 In other words, Td values ​​23A and 23B is 0.25H. 但是,Td可以是大于OH但小于0.5H的任何值。 However, Td may be any value greater than but less than 0.5H OH's.

[0335] 尽管参照图23A和23B描述了CS干线的电压相位和周期,CS干线的电压波形不限于此,CS干线可以是任何波形,只要满足下列两个条件之一。 [0335] While a period of CS main lines and the voltage phase reference to FIGS. 23A and 23B, voltage waveforms of the CS trunks are not limited thereto, CS main lines can be any waveform, as long as one of the following two conditions are met. 第一个条件是在对应栅极总线的电压从VgH变为HgL后,电压VCSVtypeRl的第一变化是电压增加,而在对应栅极总线的电压从VgH变为HgL后,电压VCSVtypeR2的第一变化是电压减小。 After the first condition is a voltage corresponding to the gate bus line changes from VgH HGL, the first variation voltage is VCSVtypeRl voltage increases, the voltage corresponding to the gate bus line changes from VgH into HGL, the first variation voltage VCSVtypeR2 voltage is reduced. 第二条件是在对应栅极总线的电压从VgH变为HgL后,电压VCSVtypeRl的第一变化是电压减小,而在对应栅极总线的电压从VgH变为HgL后,电压VCSVtypeR2的第一变化是电压增加。 The second condition is the corresponding voltage of the gate bus from VgH to HGL, VCSVtypeRl first variation voltage is the voltage decreases and the voltage corresponding to the gate bus line changes from VgH into HGL, the first variation voltage VCSVtypeR2 voltage is increased.

[0336] 图24A和24B概述液晶显示器的驱动状态。 [0336] Figures 24A and 24B overview driving state of the liquid crystal display. 根据图23A和23B所示示例的子像素的多个驱动电压,液晶显示器的驱动状态也分为两种类型。 The plurality of driving voltages 23A and 23B of the example shown in FIG sub-pixels, the driving state of the liquid crystal display are also classified into two types. 图24A的驱动状态对应图23A的驱动电压波形,而图24B的驱动状态对应图23B的驱动电压波形。 FIG 24A corresponds to the driving state of the drive voltage waveforms in FIG. 23A, FIG. 24B and the driving state corresponding to driving voltage waveforms in FIG. 23B.

[0337] 图24A和24B示意性地表示在按矩阵排列的多个像素中“从η行到η+7行的8行”Χ “从m列到m+5列的6列”的像素驱动状态。 [0337] Figures 24A and 24B schematically showing a plurality of pixels arranged in a matrix of "[eta] from the row to row η + 8 7 rows" [chi] "from column m to column m + 6 of 5 'pixel drive status. 每个像素具有不同亮度的子像素。 Each pixel has sub-pixels with different brightness. 即表示为“b (亮)”的子像素和表示为“d (暗)”的子像素。 That is expressed as "B (bright)," and the sub-pixel is represented as "D (dark)" sub-pixel. 图24A和24B基本上与图17相同。 24A and 24B are substantially the same as in FIG. 17.

[0338] 图24A和图24B的注意点是,是否满足面积比灰度等级板的要求。 Precautions [0338] FIGS. 24A and 24B is whether the area ratio gray scale panel satisfies the requirements. 面积比灰度等级板具有五个要求。 Five claim having an area ratio gray scale panel.

[0339] 第一要求是当显示中间灰度等级时,每个像素由不同亮度的多个像素组成。 [0339] The first requirement is that when displaying intermediate gray scale level, each pixel is composed of a plurality of luminance pixels of different compositions.

[0340] 第二要求是不考虑时间,不同亮度的子像素亮度级不变。 [0340] The second requirement is that irrespective of time, the luminance of the sub-pixels of different brightness level unchanged.

[0341] 第三要求是不同亮度的子像素精巧地排列。 [0341] The third requirement is that sub-pixels of different brightness are arranged elaborately.

[0342] 第四要求是在所有帧中相反极性的像素精巧地排列。 [0342] The fourth requirement is that pixels are arranged opposite polarity elaborately in all frames.

[0343] 第五要求是在所有帧中相同极性、相同亮度级(特别是最亮的子像素)的子像素精巧地排列。 [0343] The fifth requirement is arranged in the same polarity, the same brightness level (especially the brightest sub-pixels) sub-pixels in all frames delicately.

[0344] 按照第一要求来验证。 [0344] According to a first verification requirements. 这里,每个像素由两个不同亮度的子像素组成。 Here, each pixel consists of two sub-pixels of different luminance components. 特别是,例如在图24A中,η行和m列的像素由表示为“b (亮)”的高亮度子像素和表示为“d(暗)”的低亮度子像素组成。 In particular, for example in FIG. 24A, η rows and m columns of pixels by the high-brightness sub-pixel indicated as "B (bright)" and is expressed as "D (dark)," a low-brightness sub-pixels. 因此,满足第一要求。 Thus, to meet the first requirement.

[0345] 按照第二要求来验证。 [0345] According to a second verification requirements. 液晶显示器以规则的时间间隔交替不同驱动状态的两种显不状态。 The liquid crystal display alternately at regular time intervals of two distinctly different from the driving state is not state. 图24A和24B表不对应于两种显不状态的驱动状态符合闻売度子像素和低売度子像素的位置。 Table 24A and 24B do not correspond to the driving state is not a state of two distinctly heard bai meet position of the sub-pixels and sub-pixels of the low-bai. 因此,满足第二要求。 Thus, to meet the second requirement.

[0346] 按照第三要求来验证。 [0346] According to a third verification requirements. 在图24A和24B中,不同亮度级(即,表示为“b (亮)”的子像素和表示为“d(暗)”的子像素)的子像素按棋盘格式排列。 In FIGS. 24A and 24B, different brightness levels (i.e., denoted as "B (bright)," and the sub-pixel is represented as "D (dark)" sub-pixels) arranged in a checkerboard format subpixel. 液晶显示器的可视观察没有出现诸如使用不同亮度子像素降低分辨率的显示问题。 Visual observation of the liquid crystal display does not show the use of different problems such as reduced resolution sub-pixel luminance occurs. 因此,满足第三要求。 Therefore, to meet the third requirement.

[0347] 按照第四要求来检验。 [0347] According to a fourth test requirements. 在图24A和24B中相反极性的像素排列成棋盘格式。 24A and 24B in the opposite polarity of pixels arranged in a checkerboard format. 特别是,例如在图24A中,在n+2行和m+2列中的像素具有“ + ”极性。 In particular, for example, in FIG. 24A, in row n + 2 and column m + 2 has a pixel "+" polarity. 从这个像素开始,沿行方向和列方向在和“ + ”之间每隔一个像素改变极性。 From this pixel row direction and the column direction and intervals between the "+" a pixel changes polarity. 对于不能满足第四要求的液晶显示器,认为是与像素的驱动极性在“ + ”和之间变化同步看到显示器的闪动。 For the liquid crystal display can not satisfy the fourth requirement, that is the pixels in the drive polarity "+" and variations seen between synchronous flashing display. 但是,当目视检验实施例的液晶显示器时就看不到闪动。 However, when the liquid crystal display visual inspection embodiment will not see the flashing. 因此,满足第四要求。 Therefore, to meet the fourth requirement.

[0348] 按照第五要求来检验。 [0348] According to the fifth test requirements. 在图24A和24B中,观察相同亮度级的子像素驱动极性,每两行子像素(即,每隔一个像素宽度)反转驱动极性。 In FIGS. 24A and 24B, the same was observed pixel brightness level of the sub-driving polarity every two rows of sub-pixels (i.e., every other pixel width) polarity inversion driving. 特别是,例如在图24A的n_B行中,在m+l、m+3和m+5列中的子像素为“b (亮)”,并且所有这些子像素的极性为在n+l_A行中,在m、m+2和m+4列的像素为“b (亮)”,并且所有这些子像素的极性为在n+l_B行中,在m+1、m+3和m+5列中的子像素为“b (亮)”,并且所有这些子像素的极性为“ + ”。 In particular, in the example of FIG. 24A n_B row, the m + l, m + 3 and m + 5 in the sub-pixel is "B (bright)", and the polarity of all these sub-pixels as n + l_A row, m, m + 2 and m + 4 pixel column is "B (bright)", and the polarity of all these sub-pixels as n + l_B row, the m + 1, m + 3 and m +5 sub-pixel column is "B (bright)", and the polarity of all these sub-pixels is "+." 在n+2_A行中,在m、m+2和m+4列的像素为“b (亮)”,并且所有这些子像素的极性为“ + ”。 In row n + 2_A, at m, m + 2 and m + 4 pixel column is "B (bright)", and the polarity of all these sub-pixels is "+." 对于不满足第五要求的液晶显示器,认为是与像素的驱动极性在“ + ”和之间变化同步看到显示器的闪动。 For the liquid crystal display does not satisfy the fifth requirement, that is the pixels in the drive polarity "+" and variations seen between synchronous flashing display. 但是,当目视检验根据本发明的液晶显示器时就看不到闪动。 However, visual inspection when the liquid crystal display according to the present invention will not see the flashing. 因此,满足第五要求。 Therefore, to meet the requirements of the fifth.

[0349] 当通过改变CS电压的振幅VCSpp来观察液晶显示器时,在倾斜观察期间,随着显不对比度的提闻,视角特性就提闻,因为CS电压的振幅VCSpp从OV开始增加(0V用于支持除了根据本发明液晶显示器之外的一般液晶显示器)。 [0349] When observed the liquid crystal display by changing the CS voltage amplitude VCSpp, during oblique observation, with no explicit mention smell contrast, viewing angle characteristic smell to mention, as the amplitude VCSpp CS voltage begins to increase from OV (0V with in addition to supporting the liquid crystal display according to the present invention than the conventional liquid crystal display). 尽管根据显示的图像视角特性的提高似乎稍有不同,但是当VCSpp设定为使VLCaddpp值在普通驱动模式(VCSpp为0V)的液晶显示器域值电压的0.5-2倍之内时,则实现最佳提高。 Although it seems to improve slightly different according to the viewing angle characteristics of the displayed image, but when VCSpp set so that the value is within VLCaddpp 0.5-2 times the normal driving mode (VCSpp was 0V) of the liquid crystal display of the threshold voltage is achieved most good raise.

[0350] 因此,根据本发明第二方面实施例的液晶显示器通过施加振荡电压到存储电容计数器电极上而提高视角特性,由此实现多像素显示,其中施加到存储电容反电极上的振荡电压振荡周期等于或短于一个水平扫描周期。 [0350] Thus, the liquid crystal display according to the second aspect of the embodiment of the present invention by applying an oscillating voltage to the storage capacitor counter electrode to improve the viewing angle characteristics, thereby achieving multi-pixel display, wherein the oscillating voltage applied to the storage capacitor counter electrode oscillation period shorter than or equal to one horizontal scanning period. 但是,当施加到CS总线上的振荡电压的振荡周期短时,就相当难以在CS总线的高负载电容和电阻的大液晶显示器、短水平扫描周期的高分辨率液晶显示器或高速驱动和短垂直、水平扫描周期的显示器上实现多像素显示。 However, when a voltage is applied to the oscillation period of the oscillation of the CS bus line short, it is rather difficult in a large liquid crystal display of high load capacitance and resistance of the CS bus line, a short horizontal scanning period of the high-resolution liquid crystal display or high-speed driving and short vertical , multi-pixel display on a display horizontal scanning period.

[0351] 这个问题将参照图25-28来描述。 [0351] This problem will be described with reference to Figures 25-28.

[0352] 图25A是表示在根据本发明第二方面实施例的液晶显示器中,用于将振荡电压供给CS总线的的结构示意图。 [0352] FIG. 25A is a liquid crystal display according to the second aspect of the embodiment of the present invention, the structural diagram of the oscillating voltage supplied to the CS bus line. 振荡电压从CS干线供给在液晶显示板中设置的多个CS总线。 Oscillating voltage supplied from a plurality of CS CS trunks provided in the liquid crystal display panel bus. 振荡电压经过连接点ContPl和ContP2并经过ContP3和ContP4,从CS总线电压发生器电路供给CS干线。 Oscillating voltage via connection point and through ContP3 ContPl and ContP2 and ContP4, CS bus line CS voltage generator circuit is supplied from the mains. 由于增加液晶显示板的尺寸,因此从显示板中心的像素到连接点ContPl和ContP2的距离增加,使它不可能忽略中心像素和连接点之间的负载阻抗。 Since the size of the liquid crystal display plate is increased, thus increasing the distance from the center pixel of the display panel and the connection point ContPl ContP2 to make it impossible to ignore the load impedance between the pixel and the center point of attachment. 负载阻抗的主要元件包括像素的液晶电容(CLC)和存储电容(CCS)、CS总线的电阻RCS和CS干线的电阻Rtrunk。 The main element comprises a load impedance of the liquid crystal pixel capacitance (CLC) and storage capacitance (CCS), the resistor RCS and CS trunk CS bus resistance Rtrunk. 负载阻抗的第一近似值可以是由图25B所示的上述电容和电阻组成的低通滤波器。 A first approximation of the load impedance can be a low-pass filter and the resistance of the capacitor shown in FIG. 25B thereof. 负载阻抗的值是液晶显示板位置的函数。 Value of the load impedance is a function of the position of the liquid crystal display panel. 例如,它是距连接点C0ntPl、ContP2、ContP3和ContP4距离的函数。 For example, it is the function from the point of attachment C0ntPl, ContP2, ContP3 and ContP4 distance. 特别是,负载阻抗随距离连接点距离的增加而增加,随距离连接点距离的减小而减小。 In particular, the load impedance increases with distance from the connection point distance increases, decreases as the distance from the point of connection is reduced.

[0353] 也就是说,由振荡电压发生器电路产生的CS总线电压受CR低通滤波器近似的CS总线负载的影响,CS总线经过波形钝化改变在平板上的位置。 [0353] That is, the CS bus voltage generated by an oscillating voltage generator circuit is affected by the low pass filter approximation CR CS bus load, the wave form through the CS bus line to change the position on the plate.

[0354] 如本发明第一方面的实施例所述,振荡电压施加给CS总线,以便构成两个或更多个子像素的各个像素并改变子像素的亮度。 [0354] The embodiment described in the first aspect of the present invention, the oscillating voltage is applied to the CS bus line so as to constitute two or more sub-pixel of each pixel and sub-pixel luminance changes. 即,根据本发明实施例的液晶显示器使用这样的结构和驱动方法:根据CS总线的振荡电压形成子像素电极的电压波形,并根据CS总线的振荡波形改变有效电压。 That is, a liquid crystal display according to an embodiment of the present invention and the driving method of such a configuration: forming a sub-pixel electrode voltage waveform based on the oscillation of the CS bus line and changing the effective voltage in accordance with the oscillating waveform of the CS bus line. 因此,如果CS总线电压波形从一个位置变到另一个位置,子像素电极的有效电压也是如此。 Thus, if the CS bus line voltage waveform is changed from one position to another position, the effective voltage of the sub-pixel electrode as well. 换句话说,如果CS总线电压的波形钝化改变位置,显示亮度也随位置变化,从而得到不规则的显示亮度。 In other words, if the voltage waveform of the CS bus passivation change position, the display position changes with the brightness, to thereby obtain an irregular display brightness.

[0355] 通过增加CS总线的振荡周期校正显示亮度不规则的能力是根据本发明第三方面液晶显示器的优点。 [0355] The ability luminance irregularity according to a third aspect of the present invention, the advantages of a liquid crystal display is corrected by increasing the oscillation period of the display CS bus. 下面将作解释。 I will explain below.

[0356] 图26和27示意性地表示在CS负载保持不变的情形子像素电极的振荡电压波形。 [0356] Figures 26 and 27 schematically represents a waveform of an oscillating voltage in the case of CS subpixel electrode load remains unchanged. 图26和27是假定在CS总线电压不是振荡电压时子像素电极的电压为“0V”,以及由CS总线的振动产生的子像素电极电压的振幅是“IV”的示意图。 26 and 27 are assumed in the CS bus line voltage is not oscillating voltage sub-pixel electrode voltage of "0V", the sub-pixel electrode and the amplitude of the voltage generated by the vibration is a schematic diagram of the CS bus line "IV" of. 图26中波形(a)-(e)表示CS电压没有波形钝化的波形,即,CR低通滤波器的CR时间常数是“0H”,而图27中波形(a)-(e)表示当CR低通滤波器的CR时间常数是“0.2H”时的波形钝化。 FIG 26 is a waveform (a) - (e) is not the CS voltage waveform rounding waveform, i.e., CR time constant of the CR low pass filter is "0H", the waveform of FIG. 27 (a) - (e) represents when the CR time constant of the CR low pass filter is a waveform rounding at the "0.2H". 图26和27示意性地表示当CR低通滤波器的CR时间常数分别是“0H”和“0.2H”时子像素电极电压的电压波形,以及CS总线振荡电压的振荡周期被改变。 26 and 27 schematically showing when the CR time constant of the CR low pass filter are voltage waveforms at the sub-pixel electrode voltage "0H" and "0.2H", and the oscillation period of the oscillating voltage of the CS bus line is changed. 图26和27中的波(a)-(e)表示波形振荡周期分别是1H、2H、4H、8H的情形。 FIG waves 26 and 27 (a) - (e) shows the waveform of the oscillation period are 1H, 2H, case 4H, 8H in.

[0357] 当图26和27相比较时,可以看出图26和27中波形差随振荡周期的增加而减小。 [0357] When comparing FIGS. 26 and 27, it can be seen in FIGS. 26 and 27 increases the oscillation period of a waveform difference is reduced. 这种趋势在图28中定量表示。 This trend is quantified in FIG. 28.

[0358] 图28表示基于图27的波形比CS总线电压的振荡周期(一个周期对应一个水平扫描周期:1H)计算出的振荡电压的平均值和有效值的关系。 [0358] FIG 28 represents the ratio of the voltage oscillation period of the CS bus line (a period corresponding to one horizontal scanning period: 1H) based on the average value of the waveform of FIG. 27 and the relationship between the calculated effective value of the oscillating voltage. 从图28中可以看出,在CR时间常数是OH时和CR时间常数是0.2H时之间平均电压和有效电压的偏差随CS总线振荡周期的增加而减小。 As can be seen from FIG. 28, the CR time constant is OH and when the CR time constant is the average voltage deviation between 0.2H and when the effective voltage increases the oscillation period of the CS bus line is reduced. 可以看出,可以很大程度地减小波形钝化的影响,特别是当CS总线振荡电压的振荡周期大于CS总线的CR时间常数(负载阻抗的近似值)的8倍时。 As can be seen, it can greatly reduce the influence of rounding of a waveform extent, especially when the CR time constant of the oscillation period of the oscillating voltage is larger than the CS bus line CS bus lines (approximation of the load impedance) of 8 times.

[0359] 这样,通过增加CS总线振荡电压的振荡周期,可能降低CS总线波形钝化造成的显示亮度不规则。 [0359] Thus, the display luminance irregularities by increasing the oscillation period of the oscillating voltage of the CS bus line and the CS bus line may be reduced due to waveform deterioration. 可以很大程度地降低波形钝化的影响,特别是当CS总线振荡电压的振荡周期大于CS总线的CR时间常数(负载阻抗的近似值)的8倍时。 It can be reduced greatly affect the waveform rounding, especially when the CR time constant oscillation period of the oscillating voltage is larger than the CS bus line CS bus lines (approximation of the load impedance) of 8 times.

[0365] 在图29中要注意的第一点是:在列方向相邻行中像素的相邻子像素(例如,对应CLCB_n,m和CLCA_n+l,m的子像素)的CS总线彼此电绝缘。 [0365] In FIG. 29 a first point to note is that: the sub-pixels of adjacent rows of adjacent pixels in the column direction (e.g., corresponding to CLCB_n, m and CLCA_n + l, m sub-pixel) of the CS bus line electrically to each other insulation. 特别是,例如用于η行子像素CLCB_n,m的CS总线CSBL_B_n和用于列方向相邻行像素的子像素CLCA_n+l,m的总线CSBL_A_n+1彼此电绝缘。 In particular, for example, the row of sub-pixels η CLCB_n, m and the CS bus CSBL_B_n for the sub-pixels adjacent in the column direction row of pixels CLCA_n + l, m bus CSBL_A_n + 1 electrically insulated from each other.

[0370] 四组电绝缘的CS总线分别连接到上述表I中所示的四个CS干线上。 [0370] The four sets of electrically insulating CS bus line are connected to the four CS trunks shown in Table I above.

[0371] 图30A和30B表示根据栅极总线的电压波形的CS总线振荡周期和相位,以及表示子像素电极的电压。 [0371] FIGS. 30A and 30B shows a CS bus oscillation period and phase gate bus voltage waveform, and represents the sub-pixel electrode voltage. 图30A和30B对应上述图23A和23B。 30A and 30B correspond to the above-described FIGS. 23A and 23B. 与图23A和23B相同的元件用与图23A和23B相同的附图标记/符号表示,在此省略描述。 Represents the same elements 23A and 23B with FIGS. 23A and 23B with the same reference numerals / symbols, description thereof is omitted here. 液晶显示器一般以规则的时间间隔反转施加到每个像素的液晶层上的电场方向,因此,需要考虑对应于电场方向的两种类型的驱动电压波形。 The liquid crystal display generally inverted at regular time intervals electric field applied to the direction of the liquid crystal layer of each pixel, therefore, need to consider the direction of the electric field corresponding to the two types of drive voltage waveform. 图30A和30B中分别表示这两种类型的驱动状态。 FIGS 30A and 30B respectively represent the two types of driving state.

[0372]图 30A 和30B 中要注意的第一点是:CSVtypeAl、CSVtypeA2、CSVtypeA3 和CSVtypeA4 的电压VCSVtypeAl、VCSVtypeA2、VCSVtypeA3 和VCSVtypeA4 的振荡周期全都是水平扫描周期的4倍(4H)。 [0372] The first 30A and 30B, points to note are: CSVtypeAl, CSVtypeA2, CSVtypeA3 and the voltage VCSVtypeAl CSVtypeA4, VCSVtypeA2, VCSVtypeA3 and the oscillation period are all 4 times VCSVtypeA4 (4H) horizontal scanning period.

[0377] 尽管参照图30A和30B描述了CS干线电压的周期和相位,但是CS干线的电压波形不限于此。 [0377] Although described with reference to FIGS. 30A and 30B and the phase of a CS cycle of the mains voltage, but the voltage waveform of CS main lines are not limited thereto. CS干线可以是满足下列两个条件的其它波形。 CS trunk other waveform may be the following two conditions are met.

[0378] 第一个条件是:对应栅极总线的电压从VgH变为VgL后的电压VCSVtypeAl的第一变化是电压升高,对应栅极总线的电压从VgH变为VgL后的电压VCSVtypeA2的第一变化是电压降低,对应栅极总线的电压从VgH变为VgL后的电压VCSVtypeA3的第一变化是电压降低,对应栅极总线的电压从VgH变为VgL后的电压VCSVtypeA4的第一变化是电压升高。 [0378] The first condition is that: after the first change in the voltage corresponding to the voltage VCSVtypeAl gate bus line changes from VgH into VgL voltage is increased, the voltage corresponding to the first voltage VCSVtypeA2 after the gate bus line falls from VgH to VgL a voltage variation is reduced, after a first change in the voltage corresponding to the voltage VCSVtypeA3 gate bus line changes from VgH into VgL voltage is reduced, after a first change in the voltage corresponding to the voltage VCSVtypeA4 gate bus line changes from VgH into VgL voltage increased. 图30A所示的驱动电压波形满足这个条件。 A drive voltage waveform shown in FIG. 30A satisfy this condition.

[0379] 第二个条件是:对应栅极总线的电压从VgH变为VgL后的电压VCSVtypeAl的第一变化是电压降低,对应栅极总线的电压从VgH变为VgL后的电压VCSVtypeA2的第一变化是电压升高,对应栅极总线的电压从VgH变为VgL后的电压VCSVtypeA3的第一变化是电压升高,对应栅极总线的电压从VgH变为VgL后的电压VCSVtypeA4的第一变化是电压降低。 [0379] The second condition is that: after the first change in the voltage corresponding to the voltage VCSVtypeAl gate bus line changes from VgH into VgL voltage is lowered, a voltage corresponding to the voltage of the gate bus line VCSVtypeA2 from VgH into VgL first voltage change is increased, after a first change in the voltage corresponding to the voltage VCSVtypeA3 gate bus line changes from VgH into VgL voltage is increased, corresponding to a first change in the voltage of the voltage VCSVtypeA4 gate bus line falls from VgH to VgL is voltage decreases. 图30B所示的驱动电压波形满足这个条件。 A drive voltage waveform shown in FIG. 30B satisfy this condition.

[0380] 但是,出于下面描述的理由,优选使用图30A和30B所示的波形。 [0380] However, for the reasons described below, the waveforms shown in FIGS. 30A and 30B is preferably used.

[0381] 在图30A和30B中,振荡周期是不变的。 [0381] In FIGS. 30A and 30B, the oscillation period is constant. 这可以简化信号发生器电路。 This can simplify the signal generator circuit.

[0382] 而且,在图30A和30B中,振荡占空比不变。 [0382] Further, in FIGS. 30A and 30B, the duty ratio of oscillation constant. 这样可能保持振荡振幅不变,并且当振荡电压用作CS总线电压时,施加到液晶显示层的电压变化量取决于振荡的振幅和占空比,因此简化信号发生器电路。 Thus the oscillation amplitude may be kept constant, and when the oscillating voltage is used as the CS bus voltage, the voltage applied to the liquid crystal display layer depends on the amount of change of amplitude and duty cycle oscillations, thus simplifying the signal generator circuit. 因此,振荡占空比保持不变,就可能使振荡的振幅不变。 Thus, the oscillation duty is kept constant, can make constant the amplitude of oscillation. 例如,占空比设定为1:1。 For example, the duty ratio set to 1: 1.

[0383] 而且,在图30A和30B中,对于任何CS振荡电压,存在超出180度相位的振荡电压(相反相位的振荡电压)。 [0383] Further, in FIGS. 30A and 30B, for any CS oscillating voltage, there is a 180 degree phase exceeds oscillating voltage (oscillating voltage in opposite phase). 即,四个电绝缘CS干线组成CS干线对(两对),其相互供给超出180度相位的振荡电压。 That is, four electrically insulating CS trunk CS main lines consisting of (two), which each supply voltage exceeds 180 degrees phase of the oscillation. 这就可能使流过存储电容反电极的电流量最小,因此简化连接反电极的驱动电路。 This may make the amount of current flowing through the storage capacitor counter electrode of the minimum, thus simplifying the driving circuit connected to the counter electrode.

[0384] 图31A和31B概述本实施例液晶显示器的驱动状态。 [0384] FIGS. 31A and 31B Overview of the driving state of the liquid crystal display of the present embodiment embodiment. 根据子像素驱动电压的极性,液晶显示器的驱动状态也分为两种类型,如图30A和30B所示的情形。 The polarity of the driving voltage of the sub-pixel, the driving state of the liquid crystal display are also classified into two types, 30A and 30B in the case shown in FIG. 图31A中的驱动状态对应于图30A的驱动电压波形,同时,图31B中的状态对应于图30B驱动电压波形的驱动状态。 The driving state of FIG. 31A corresponds to the driving voltage waveforms of FIG. 30A, while the state in FIG. 31B corresponds to the driving state of the driving voltage waveform in FIG. 30B. 图31A和31B对应于上述图24A和24B。 31A and 31B corresponds to FIG 24A and 24B.

[0385] 图31A和31B中的注意点是,是否满足面积比灰度等级板的要求。 [0385] FIGS. 31A and 31B in the noted point that meets the area ratio gray scale panel requirements. 按照下列面积比灰度等级板的五个要求来验证。 According to the following five requirements area ratio gray scale panel to verify.

[0386] 第一要求是当显示中间灰度等级时,每个像素由多个不同亮度子像素组成。 [0386] The first requirement is that when displaying intermediate gray scale level, the luminance of each pixel is composed of a plurality of different sub-pixels.

[0387] 第二要求是不管时间,亮度不同的子像素亮度级不变。 [0387] The second requirement is that regardless of the time, different luminance sub-pixel luminance level unchanged.

[0388] 第三要求是不同亮度的子像素精巧地排列。 [0388] The third requirement is that sub-pixels of different brightness are arranged elaborately.

[0389] 第四要求是在所有帧中相反极性的像素精巧地排列。 [0389] The fourth requirement is that pixels are arranged opposite polarity elaborately in all frames.

[0390] 第五要求是在所有帧中相同极性、相同亮度级(尤其是最亮的子像素)的子像素精巧地排列。 [0390] The fifth requirement is the same polarity in all the frames, the sub same luminance level (especially the brightest sub-pixel) of the pixels are arranged elaborately.

[0391] 按照第一要求来验证。 [0391] According to a first verification requirements. 在图31A和31B中,每个像素由两个亮度不同的子像素组成。 In FIGS. 31A and 31B, each pixel consists of two sub-pixels of different brightness. 特别是,例如在图31A中,η行和m列的像素由表示为“b (亮)”的高亮度子像素和表示为“d(暗)”的低亮度子像素组成。 In particular, for example in FIG. 31A, η rows and m columns of pixels is denoted by "B (bright)," high-brightness sub-pixel and is represented as "D (dark)," a low-brightness sub-pixels. 因此,满足第一要求。 Thus, to meet the first requirement.

[0392] 按照第二要求来验证。 [0392] According to a second verification requirements. 液晶显示器以规则时间间隔交替不同驱动状态的两种显示状态。 The liquid crystal display alternately at regular time intervals different from the driving state of two display states. 图31A和31B表示对应于两个显示状态的驱动状态符合高亮度子像素和低亮度子像素的位置。 31A and 31B showing two display state corresponding to driving state meet high brightness and low-brightness sub-pixel a sub-pixel location. 因此,满足第二要求。 Thus, to meet the second requirement.

[0393] 按照第三要求来验证。 [0393] According to a third verification requirements. 在图31A和31B中,不同亮度级的子像素(B卩,表示为“b(亮)”的子像素和表示为“d(暗)”的子像素)按棋盘格式排列。 In FIGS. 31A and 31B, different brightness levels of the sub-pixel (B Jie, the sub-pixel indicated as "B (bright)" and is expressed as "D (dark)" sub-pixels) arranged in a checkerboard format. 液晶显示器的目视观察看不出显示问题,例如由于不同亮度子像素降低分辨率。 Visually observing the liquid crystal display can not see display problems, for example due to different sub-pixel luminance reduced resolution. 因此,满足第三要求。 Therefore, to meet the third requirement.

[0394] 按照第四要求来验证。 [0394] According to a fourth verification requirements. 在图31A和31B中,相反极性的像素排列成棋盘格式。 In FIGS. 31A and 31B, pixels of opposite polarity are arranged in a checkerboard format. 特别是,例如在图31A中,在n+2行和m+2列中的像素具有“ + ”极性。 In particular, for example, in FIG. 31A, in row n + 2 and column m + 2 has a pixel "+" polarity. 从这个像素开始,沿行方向和列方向在和“+”之间每隔一个像素改变极性。 From this pixel row direction and the column direction and intervals between the "+" a pixel changes polarity. 对于不能满足第四要求的液晶显示器,认为是与像素的驱动极性在“+”和之间变化同步看到显示器的闪动。 For the liquid crystal display can not satisfy the fourth requirement, that is the pixels in the drive polarity "+" and variations seen between synchronous flashing display. 但是,当目视检验实施例的液晶显示器时看不到闪动。 However, when you do not see the flashing visual inspection embodiment of the liquid crystal display. 因此,满足第四要求。 Therefore, to meet the fourth requirement.

[0395] 按照第五要求来验证。 [0395] According to a fifth verification requirements. 在图31A和31B中,观察相同亮度级的子像素驱动极性,每两行子像素(即,每隔一个像素宽度)反转驱动极性。 In FIGS. 31A and 31B, the same was observed pixel brightness level of the sub-driving polarity every two rows of sub-pixels (i.e., every other pixel width) polarity inversion driving. 特别是,例如在n_B行中,在m+1、m+3和m+5列中的子像素为“b (亮)”,并且所有这些子像素的极性为在n+l_A行中,在m、m+2和m+4列的像素为“b (亮)”,并且所有这些子像素的极性为在n+l_B行中,在m+1、m+3和m+5列中的子像素为“b (亮)”,并且所有这些子像素的极性为“ + ”。 In particular, for example, in n_B row, m + 1, m + 3 and m + 5 in the sub-pixel is "B (bright)", and the polarity of all these sub-pixels as n + l_A row, at m, m + 2 and m + 4 pixel column is "B (bright)", and the polarity of all these sub-pixels as n + l_B row, the m + 1, m + 3 and m + 5 column the sub-pixel "B (bright)", and the polarity of all these sub-pixels is "+." 在n+2_A行中,在m、m+2和m+4列的像素为“b (亮)”,并且所有这些子像素的极性为“ + ”。 In row n + 2_A, at m, m + 2 and m + 4 pixel column is "B (bright)", and the polarity of all these sub-pixels is "+." 对于不满足第五要求的液晶显示器,认为是与像素的驱动极性在“ + ”和之间变化同步看到显示器的闪动。 For the liquid crystal display does not satisfy the fifth requirement, that is the pixels in the drive polarity "+" and variations seen between synchronous flashing display. 但是,当目视检验根据本发明的液晶显示器时看不到闪动。 However, visual inspection to see if the liquid crystal display according to the present invention is not flashing. 因此,满足第五要求。 Therefore, to meet the requirements of the fifth.

[0396] 当通过改变CS电压的振幅VCSpp来观察根据本实施例的液晶显示器时,在倾斜观察期间,随着显示对比度的抑制(surpressed),视角特性提高,因为CS电压的振幅VCSpp从OV增加(0V用于支持除了根据本发明液晶显示器之外的普通液晶显示器)。 [0396] When observed the liquid crystal display of the present embodiment by changing the CS voltage amplitude VCSpp, during oblique observation as the display contrast inhibition (surpressed), viewing angle characteristics are improved, because the amplitude VCSpp CS voltage increases from OV (0V support in addition to general liquid crystal display according to the liquid crystal display of the invention). 尽管根据显示的图像,视角特性的提高似乎稍有不同,但是当设定VCSpp以使VLCaddpp值在普通驱动模式(VCSpp为0V)的液晶显示器域值电压的0.5-2倍之内时,则实现最佳提高。 Although the displayed image, to improve the viewing angle characteristics seemed slightly different, but when VCSpp so VLCaddpp set values ​​are within 0.5-2 times the normal driving mode (VCSpp was 0V) of the liquid crystal display of the threshold voltage is achieved best improve.

[0397] 概括而言,本实施例有可能设定施加给存储电容反电极的振荡电压的振荡周期为液晶显示器水平扫描周期的4倍,液晶显示器通过施加振荡电压给存储电容反电极而提高视角特性,因此,实现多像素显示。 [0397] In summary, the present embodiment it is possible to set the oscillation period of oscillating voltages applied to the storage capacitor counter electrode of the liquid crystal display 4 times the horizontal scanning period, the oscillating voltage to the liquid crystal display of the storage capacitor counter electrode is improved by applying Angle characteristics, therefore, multi-pixel display. 甚至在具有CS总线的高负载电容和电阻的大液晶显示器上、在具有短水平扫描周期的高分辨率液晶显示器上、或具有高速驱动和短垂直、水平扫描周期的液晶显示器上,也容易实现多像素显示。 Even on a large liquid crystal display high load capacitance and resistance of the CS bus line has, on the high-resolution liquid crystal display having a short horizontal scanning period, or with a high-speed driving and short vertical liquid crystal display, a horizontal scanning period, but also easy to implement multi-pixel display.

[0407] 图33A和33B表示根据栅极总线电压波形的CS总线振荡周期和相位,并示出子像素电极的电压。 [0407] FIGS. 33A and 33B shows a CS bus oscillation period and phase gate bus line voltage waveform, and shows the voltage of the sub-pixel electrode. 图33A和33B对应于前面实施例的图30A和30B。 33A and 33B correspond to the embodiment of FIG. 30A and 30B in front. 与图30A和30B相同的元件用与图30A和30B相同的附图标记/符号表示,其中描述省略。 Denoted 30A and 30B with the same reference numerals / symbols are the same elements in FIG. 30A and 30B, which description is omitted. 液晶显示器一般以规则的时间间隔反转施加到每个像素的液晶层上的电场方向,因此,需要考虑对应于电场方向的两种类型的驱动电压波形。 The liquid crystal display generally inverted at regular time intervals electric field applied to the direction of the liquid crystal layer of each pixel, therefore, need to consider the direction of the electric field corresponding to the two types of drive voltage waveform. 图33A和33B中分别表示这两种类型的驱动状态。 FIGS 33A and 33B respectively represent the two types of driving state.

[0408] 在图33A和33B中要注意的第一点是=CSVtypeBl和CSVtypeB2的电压VCSVtypeBl和VCSVtypeB2的振荡周期全都是水平扫描周期的2倍(2H)。 [0408] In a first point in FIGS. 33A and 33B to be noted that CSVtypeB2 = CSVtypeBl and the oscillation period and the voltage VCSVtypeBl VCSVtypeB2 are all twice (2H) horizontal scanning period.

[0413] 尽管参照图33A和33B描述了CS干线的电压周期和相位,但是CS干线的电压波形不限于此。 [0413] Although described with reference to FIGS. 33A and 33B and the phase of a CS trunk line voltage period, the voltage waveform of CS main lines but is not limited thereto. CS干线可以是满足下列两个条件的其它波形。 CS trunk other waveform may be the following two conditions are met.

[0414] 第一个条件是:对应栅极总线的电压从VgH变为VgL后的电压VCSVtypeBl的第一变化是电压升高,对应栅极总线的电压从VgH变为VgL后的电压VCSVtypeB2的第一变化是电压降低。 [0414] The first condition is that: after the first change in the voltage corresponding to the voltage VCSVtypeBl gate bus line changes from VgH into VgL voltage is increased, the voltage corresponding to the first voltage VCSVtypeB2 after the gate bus line falls from VgH to VgL a voltage variation is reduced. 图33A满足这个条件。 Figure 33A satisfy this condition.

[0415] 第二个条件是:对应栅极总线的电压从VgH变为VgL后的电压VCSVtypeBl的第一变化是电压降低,对应栅极总线的电压从VgH变为VgL后的电压VCSVtypeB2的第一变化是电压升高。 [0415] The second condition is that: after the first change in the voltage corresponding to the voltage VCSVtypeBl gate bus line changes from VgH into VgL voltage is lowered, a voltage corresponding to the voltage of the gate bus line VCSVtypeB2 from VgH into VgL first change is the voltage increases. 图33B满足这个条件。 Figure 33B satisfy this condition.

[0416] 图34A和34B概述根据本实施例的液晶显示器的驱动状态。 [0416] FIGS. 34A and 34B present an overview of the driving state of the liquid crystal display device according to an embodiment. 根据子像素驱动电压的极性,液晶显示器的驱动状态也分为两种类型,如图34A和34B所示的情形。 The polarity of the driving voltage of the sub-pixel, the driving state of the liquid crystal display are also classified into two types, 34A and 34B in the case shown in FIG. 图34A中的驱动状态对应于图33A的驱动电压波形,而图34B中的状态对应于图33B驱动电压波形的驱动状态。 The driving state of FIG. 34A corresponds to the driving voltage waveforms of FIG. 33A, FIG. 34B and the state corresponding to the driving state of the driving voltage waveform in FIG. 33B. 图34A和34B对应于前述实施例的图3IA和3IB。 34A and 34B correspond to the example of FIG 3IA and 3IB embodiment.

[0417] 图34A和34B的注意点是,是否满足面积比灰度等级板的要求。 [0417] FIGS. 34A and 34B attention point is that whether the area ratio gray scale panel satisfies the requirements. 面积比灰度等级板具有五个要求 Five claim having an area ratio gray scale panel

[0418] 第一要求是当显示中间灰度等级时,每个像素由多个不同亮度子像素组成。 [0418] The first requirement is that when displaying intermediate gray scale level, the luminance of each pixel is composed of a plurality of different sub-pixels.

[0419] 第二要求是不管时间,亮度不同的子像素亮度级不变。 [0419] The second requirement is that regardless of the time, different luminance sub-pixel luminance level unchanged.

[0420] 第三要求是不同亮度的子像素精巧地排列。 [0420] The third requirement is that sub-pixels of different brightness are arranged elaborately.

[0421] 第四要求是在所有帧中相反极性的像素精巧地排列。 [0421] The fourth requirement is that pixels are arranged opposite polarity elaborately in all frames.

[0422] 第五要求是在所有帧中相同极性、相同亮度级(尤其是最亮的子像素)的子像素精巧地排列。 [0422] The fifth requirement is the same polarity in all the frames, the sub same luminance level (especially the brightest sub-pixel) of the pixels are arranged elaborately.

[0423] 按照第一要求来验证。 [0423] According to a first verification requirements. 在图34A和34B中,每个像素由两个亮度不同的子像素组成。 In FIGS. 34A and 34B, each pixel consists of two sub-pixels of different brightness. 特别是,例如在图34A中,η行和m列的像素由表示为“b(亮)”的高亮度子像素和表示为“d(暗)”的低亮度子像素组成。 In particular, for example in FIG. 34A, η rows and m columns of pixels is denoted by "B (bright)," high-brightness sub-pixel and is represented as "D (dark)," a low-brightness sub-pixels. 因此,满足第一要求。 Thus, to meet the first requirement.

[0424] 按照第二要求来验证。 [0424] According to a second verification requirements. 本实施例的液晶显示器以规则时间间隔交替不同驱动状态的两种显不状态。 The liquid crystal display of the present embodiment alternately at regular time intervals of two distinctly different driving state is not state. 图34A和34B表不对应于两个显不状态的驱动状态符合闻売度子像素和低亮度子像素的位置。 FIGS 34A and 34B corresponding to the two tables are not significant are not in line with the state of the driving state of bai smell and low-brightness sub-pixel a sub-pixel location. 因此,满足第二要求。 Thus, to meet the second requirement. [0425] 按照第三要求来验证。 [0425] According to a third verification requirements. 在图34A和34B中,不同亮度级的子像素(B卩,表示为“b(亮)”的子像素和表示为“d(暗)”的子像素)按棋盘格式排列。 In FIGS. 34A and 34B, different brightness levels of the sub-pixel (B Jie, the sub-pixel indicated as "B (bright)" and is expressed as "D (dark)" sub-pixels) arranged in a checkerboard format. 液晶显示器的目视观察看不出显示问题,例如由于不同亮度子像素降低分辨率。 Visually observing the liquid crystal display can not see display problems, for example due to different sub-pixel luminance reduced resolution. 因此,满足第三要求。 Therefore, to meet the third requirement.

[0426] 按照第四要求来验证。 [0426] According to a fourth verification requirements. 在图34A和34B中,相反极性的像素排列成棋盘格式。 In FIGS. 34A and 34B, pixels of opposite polarity are arranged in a checkerboard format. 特别是,例如在图34A中,在n+2行和m+2列中的像素具有“ + ”极性。 In particular, for example, in FIG. 34A, in row n + 2 and column m + 2 has a pixel "+" polarity. 从这个像素开始,沿行方向和列方向在和“ + ”之间每隔一个像素改变极性。 From this pixel row direction and the column direction and intervals between the "+" a pixel changes polarity. 对于不能满足第四要求的液晶显示器,认为是与像素的驱动极性在“ + ”和之间变化同步看到显示器的闪动。 For the liquid crystal display can not satisfy the fourth requirement, that is the pixels in the drive polarity "+" and variations seen between synchronous flashing display. 但是,当目视检验本实施例的液晶显示器时看不到闪动。 However, when you do not see the flashing visual inspection of a liquid crystal display of the present embodiment. 因此,满足第四要求。 Therefore, to meet the fourth requirement.

[0427] 按照第五要求来验证。 [0427] According to a fifth verification requirements. 在图34A和34B中,观察相同亮度级的子像素驱动极性,每两行子像素(即,每隔一个像素宽度)反转驱动极性。 In FIGS. 34A and 34B, the same was observed pixel brightness level of the sub-driving polarity every two rows of sub-pixels (i.e., every other pixel width) polarity inversion driving. 特别是,例如在n_B行中,在m+1、m+3和m+5列中的子像素为“b (亮)”,并且所有这些子像素的极性为在n+l_A行中,在m、m+2和m+4列的像素为“b (亮)”,并且所有这些子像素的极性为在n+l_B行中,在m+1、m+3和m+5列中的子像素为“b (亮)”,并且所有这些子像素的极性为“ + ”。 In particular, for example, in n_B row, m + 1, m + 3 and m + 5 in the sub-pixel is "B (bright)", and the polarity of all these sub-pixels as n + l_A row, at m, m + 2 and m + 4 pixel column is "B (bright)", and the polarity of all these sub-pixels as n + l_B row, the m + 1, m + 3 and m + 5 column the sub-pixel "B (bright)", and the polarity of all these sub-pixels is "+." 在n+2_A行中,在m、m+2和m+4列的像素为“b (亮)”,并且所有这些子像素的极性为“ + ”。 In row n + 2_A, at m, m + 2 and m + 4 pixel column is "B (bright)", and the polarity of all these sub-pixels is "+." 对于不满足第五要求的液晶显示器,认为是与像素的驱动极性在“ + ”和之间变化同步看到显示器的闪动。 For the liquid crystal display does not satisfy the fifth requirement, that is the pixels in the drive polarity "+" and variations seen between synchronous flashing display. 但是,当目视检验根据本发明的液晶显示器时看不到闪动。 However, visual inspection to see if the liquid crystal display according to the present invention is not flashing. 因此,满足第五要求。 Therefore, to meet the requirements of the fifth.

[0428] 当根据本实施例的液晶显示器被发明者等人改变CS电压的振幅VCSpp时,在倾斜观察期间,随着显示对比度的抑制,视角特性提高,因为CS电压的振幅VCSpp从OV增加(0V用于支持除了根据本发明液晶显示器之外的普通液晶显示器)。 [0428] When changing the amplitude VCSpp CS voltage in a liquid crystal display according to the embodiment of the present inventors embodiment, during oblique viewing, as shown to inhibit contrast, viewing angle characteristics are improved, because the amplitude VCSpp CS voltage is increased from the OV ( in addition to supporting common 0V liquid crystal display according to the liquid crystal display of the invention). 但是,进一步增加VSCpp值存在降低显示对比度的问题。 However, to further increase the value of the presence of reduced display contrast VSCpp problem. 因此,VSCpp值仅设定到充分提高视角特性不出现问题的范围。 Therefore, VSCpp value is set only to increase the range of viewing angle characteristics of the full problem does not arise. 尽管根据显示的图像,视角特性的提高似乎稍有不同,但是当设定VCSpp以使VLCaddpp值在普通驱动模式(VCSpp为0V)的液晶显示器域值电压的0.5-2倍之内时,则实现最佳提闻。 Although the displayed image, to improve the viewing angle characteristics seemed slightly different, but when VCSpp so VLCaddpp set values ​​are within 0.5-2 times the normal driving mode (VCSpp was 0V) of the liquid crystal display of the threshold voltage is achieved best to mention the smell.

[0429] 概括而言,本实施例有可能设定施加给存储电容反反电极振荡电压的振荡周期为液晶显示器水平扫描周期的2倍,液晶显示器通过施加振荡电压给存储电容反电极而提高视角特性,因此,实现多像素显示。 [0429] In summary, the present embodiment it is possible to set the oscillation period is applied to the storage capacitor electrode anti-anti oscillating voltage is twice the horizontal scanning period of a liquid crystal display, a liquid crystal display to the oscillating voltage applied to the storage capacitor counter electrode by improving a viewing angle and characteristics, therefore, multi-pixel display. 即使在具有CS总线的高负载电容和电阻的大液晶显示器上、在具有短水平扫描周期的高分辨率液晶显示器上、或具有高速驱动和短垂直、水平扫描周期的液晶显示器上,也容易实现多像素显示。 Even in the high load on a large liquid crystal display has a capacitance and resistance of the CS bus line, the high-resolution liquid crystal display having a short horizontal scanning period, or with a high-speed driving and short vertical liquid crystal display, a horizontal scanning period, but also easy to implement multi-pixel display.

[0430] 尽管在上述实施例中,CS干线电绝缘(组)数是4或2,但是根据发明第三方面实施例的液晶显示器的CS干线电绝缘(组)数不限于这些,可以是3、5或大于5。 [0430] Although in the above embodiments, the electrically insulating CS main lines (group) is four or two, but electrically insulating CS main lines of a liquid crystal display according to the third embodiment aspect of the invention (group) is not limited to these numbers, may be 3 , 5 or more. 但是,优选电绝缘CS干线数L是偶数。 Preferably, however, the number L of electrically insulating CS trunks is an even number. 这是因为当电绝缘CS干线组成CS干线对并相互供给超出180度相位的振荡电压(意味着L是偶数)时,可能使流过存储电容反电极的电流量最小。 This is because when the electrically insulating composition of the CS main lines and CS trunk of each supplying an oscillating voltage exceeds 180 degrees phase (meaning L is an even number), may cause the amount of current flowing through the counter electrodes of the storage capacitor is minimized.

[0431] 下面的表5和6表示在电绝缘CS干线的数量L是6或8的情形,对应栅极总线和CS总线的CS干线关系。 [0431] The following Table 5 and 6 represent the number of CS main lines in the electrically insulating case where L is a 6 or 8, the corresponding relationship between the gate bus line CS main lines and CS bus. 当L是偶数时,对应栅极总线和CS总线的CS干线的关系粗略地分成L/2是奇数(L = 2,6,10,14...)的情形和L/2是偶数(L = 4,8,12,16...)的情形。 When L is an even number, the corresponding relationship between the gate bus line and CS bus line CS trunk is roughly divided into L / 2 is the case (L = 2,6,10,14 ...) and odd L / 2 is an even number (L = 4,8,12,16 ...) situation. 在L/2是奇数的情形中的一般关系在下面的表5中描述,而在L/2是偶数的情形中的一般关系在下面的表6中描述,其中L = 8。 In the L / 2 is an odd number in the general relationship described below in Table 5, and in the L / 2 is an even number in the case of the general relationship described in Table 6 below, where L = 8.

[0462] 如上所述,本发明的第三方面使得容易应用多像素液晶显示器,其在倾斜观看大液晶显示器、高分辨率液晶显示器和高速驱动及短垂直、水平扫描周期的液晶显示器期间,能大大地提高显示对比度。 [0462] As described above, a third aspect of the present invention makes it easy to apply multi-pixel liquid crystal display in the oblique view a liquid crystal display, a liquid crystal display during high-speed driving and high-resolution liquid crystal display and short vertical and horizontal scanning cycle, can greatly improve display contrast. 因为通过增加施加到CS总线上的电压振荡周期,可能容易有下列问题:增加将振荡电压施加到CS总线的多像素液晶显示器的尺寸、增加CS总线的负载电容和电阻、钝化CS总线电压的波形;和增加液晶显示器的分辨率和驱动速度、减小CS总线的振荡周期、增加波形钝化的影响并造成显示屏中VLCadd的有效值明显变化,因此造成显示不规则。 Since the voltage applied to the oscillation period of the CS bus line through increased, the following problems may be susceptible to: an oscillating voltage is applied to increase the size of the multi-pixel liquid crystal display CS bus lines, increase in the load capacitance and resistance of the CS bus line, the bus voltage of the passivation CS waveform; and increasing the resolution and driving speed of a liquid crystal display, the oscillation period of CS bus lines is reduced, and the effect of increasing waveform rounding causes the display VLCadd effective value changes significantly, thus resulting in display irregularities.

[0463] 在根据本发明第二方面实施例的液晶显示器中,其使用电公共CS总线用于相邻行中像素的相邻子像素,并采用两组电绝缘的CS干线,CS总线电压的振荡周期是1H。 [0463] In the liquid crystal display according to the second aspect of the embodiment of the present invention, which uses electrically common CS bus line for an adjacent row of pixels adjacent sub-pixel, using the CS main lines and two electrically insulating, the CS bus line voltages the oscillation period is 1H. 另一方面,根据本发明第三方面实施例的液晶显示器,其使用电绝缘CS总线用于相邻行像素的相邻子像素,当使用两组电绝缘的CS干线时,可以将CS总线电压的振荡周期设定为2H,当使用四组电绝缘的CS干线时,可以将CS总线电压的振荡周期设定为4H。 On the other hand, the liquid crystal display according to an embodiment of the third aspect of the present invention is that the CS bus line for electrically insulating adjacent subpixels adjacent row of pixels, when two groups of electrical insulating CS main lines, the bus voltage can be CS the oscillation period is set to 2H, when using four sets of CS trunks electrically insulating, oscillation period of the CS bus voltage may be set to 4H.

[0464] 根据本发明第三方面实施例的液晶显示器的结构或驱动波形,通过使用电绝缘CS干线,用于相邻行像素的相邻子像素,并采用L组绝缘CS干线,可以将CS总线的振荡周期设定为水平扫描周期(LHs)的L倍。 [0464] or the structure of a liquid crystal display driving waveform according to a third aspect of the embodiment of the present invention, by using an electrically insulating CS trunks for adjacent sub-pixels of adjacent rows of pixels, and uses an insulating CS main group L may be CS bus cycle oscillation is set to a horizontal scanning period (LHS) of the L-times.

[0465] 下面将描述根据本发明第四方面实施例的液晶显示器和它的驱动方法。 Examples of the liquid crystal display device and its driving method according to a fourth aspect of the present invention [0465] will be described below.

[0466] 如上所述,根据本发明第三方面实施例的液晶显示器,使用L组电绝缘的存储电容反电极(L电绝缘的CS干线),可以将施加到存储电容反电极上的振荡电压振荡周期设定为水平扫描周期的L倍。 [0466] As described above, the liquid crystal display according to the embodiment of the present invention, a third aspect of the embodiment, the group L using electrically insulating storage capacitance counter electrodes (L electrically insulating CS trunk), the oscillating voltage may be applied to the storage capacitor counter electrode the oscillation period is set to L times the horizontal scanning period. 这样用重电负载的存储电容反电极线,可能在大的高分辨率液晶显示器上实现多像素显示。 Such a storage capacitor counter electrode line with a heavy electrical load, is possible to achieve a multi-pixel display on large high-resolution liquid crystal display.

[0467] 但是,第三方面的实施例需要使用电绝缘的存储电容反电极,用于在列方向两个相邻像素中的子像素(即,相邻行的两个像素)(例如,参见图29),意谓着每个像素需要两个CS总线。 [0467] However, embodiments of the third aspect needs to use electrically insulating the storage capacitor counter electrodes for the sub-pixels in two adjacent pixels in the column direction (i.e., two adjacent rows of pixels) (e.g., see, FIG 29), means that each pixel requires two CS bus line. 这样存在降低像素孔径比的问题。 Thus the problem exists to reduce the pixel aperture ratio. 特别是,例如,如图35A所示,使用用于子像素的CS总线排列在各个子像素的中心的结构,使它需要提供黑矩阵BMl来防止通过列方向相邻像素之间的漏光。 In particular, for example, as shown, a structure for using the CS bus line arranged in the center of each sub-pixel sub-pixels, making it necessary to provide a black matrix BMl 35A to prevent light leakage between adjacent pixels by the column direction. 因此,两个CS总线与黑矩阵交迭的面积不能用于显示。 Thus, two CS bus line overlaps with the black matrix area can not be used for display. 这就降低了像素孔径比。 This reduces the pixel aperture ratio.

[0468] 相反,根据第四方面的实施例,如图35B所示,相邻列方向两个不同像素的两个相邻子像素具有连接公共CS总线的存储电容反电极,CS总线允许设置在列方向相邻像素之间,因此使CS总线也起黑矩阵的作用。 [0468] In contrast, according to the fourth aspect of the embodiment, shown in Figure 35B, the direction of two adjacent columns of two adjacent sub-pixels having different pixel storage capacitor connected to a common CS bus line counter electrode, disposed to allow the CS bus between adjacent pixels in the column direction, so that the CS bus line also functions as a black matrix. 与图35A的结构相比,具有能够减小CS总线数的优点,通过省略另外分开提供的黑矩阵BMl而提高了像素的孔径比。 Compared with the structure of FIG. 35A, it has an advantage capable of reducing the number of CS bus, by omitting the black matrix BMl further provided separately to improve the aperture ratio of the pixel.

[0469] 就根据第三方面实施例的液晶显示器而言,为了将施加到CS总线的振荡电压振荡周期设定为水平扫描周期的L倍,要求使用L个电绝缘CS干线,要求L个驱动电源供给存储电容反电极。 [0469] For the liquid crystal display according to an embodiment of the third aspect, an oscillating voltage to be applied to the CS bus cycle oscillation is L times the horizontal scanning period, requires electrical insulating CS trunk line L, L required driving a power supply storage capacitor counter electrode. 结果,按需要增加施加给CS总线的振荡电压振荡周期,因而需要增加CS干线的数量和供给存储电容反电极的驱动电源数。 As a result, according to the need to increase the oscillation period of the oscillating voltage applied to the CS bus lines, and thus need to increase the number of drive power supply of the storage capacitor counter electrode of CS main lines. 这样,用根据第三方面实施例的液晶显示器,在增加施加到CS总线上的振荡电压的周期方面有一定的限制,因为需要增加CS干线数和供给存储电容反电极的驱动电源数。 Thus, the liquid crystal display according to the third aspect of the embodiment, in increasing the oscillation period of the CS bus line voltage is applied to certain restrictions, because of the need to increase the number of CS trunks and the number of drive power supplied to the storage capacitor counter electrode.

[0470] 相反,就根据本发明第四方面实施例的液晶显示器而言,当电绝缘CS干线数为L(L是偶数)时,振荡电压的振荡周期可以设定为水平扫描周期的2*K*L倍(K是正整数)。 [0470] In contrast, in the case of a liquid crystal display according to a fourth aspect of the embodiment of the present invention, the number of CS trunks when the electrical insulation is L (L is an even number), the oscillation period of the oscillation voltage may be set to a horizontal scanning period 2 * K * L times (K is a positive integer).

[0471] 因此,根据本发明第四方面实施例的液晶显示器比根据第三方面实施例的液晶显示器更适合大的高分辨率液晶显示器。 The liquid crystal display [0471] Thus, according to the fourth embodiment of the present invention is more suitable for large aspect ratio of the liquid crystal display according to the third aspect of the embodiment of a high-resolution liquid crystal display.

[0472] 下面将描述涉及本发明第四方面的实施例,引入实现如36A和36B所示驱动状态的液晶显示器示例。 [0472] The following embodiments relate to a fourth aspect of the present invention will be described, the liquid crystal display as an example implementation shown in FIG. 36A and 36B is introduced into the driving state. 施加到像素液晶层上的电场方向在分别对应于图24A和24B的图36A和36B之间是相反的。 The direction of electric field applied to the liquid crystal layer between the pixel respectively correspond to FIGS. 24A and 24B in FIG. 36A and 36B are reversed. 下面将描述用于实现图36A所示驱动状态的结构。 It will be described below for realizing the structure of the driving state shown in FIG. 36A. 顺便提及,为了实施图36B所示的驱动状态,施加到电源线的电压极性和存储电容电压极性可以用参照图23A和23B描述的相同方式从图36A所示的极性反转。 Incidentally, in order to implement the driving state shown in FIG. 36B, the polarity of the voltage applied to the storage capacitor and the voltage polarity of the power supply line can be used with reference to FIGS. 23A and 23B in the same manner described in FIG polarity inversion as shown in 36A. 这样有可能将第一和第二子像素固定就位(图中为“b (亮)”或“d(暗)”),同时,反转象素的显示极性(图中为“ + ”或。但是,本发明不限于此,仅允许施加到电源总线的电压反转。在这种情况下,因为第一和第二子像素随同像素极性的反转改变位置(图中为“b (亮)”或“d(暗)”),因此当像素位置固定时,可能减轻在中间灰度等级显示过程中遇到的渗色等问题。 Thus it is possible to first and second sub-pixel is fixed in position (in the figure "B (bright)" or "D (dark)"), while the polarity inversion display pixels (in the figure, "+" or. However, the present invention is not limited thereto, allowing only the voltage applied to the power bus inversion. in this case, since the first pixel and the second sub-pixel along with the polarity reversal changes position (in the figure "b (bright) "or" D (dark) "), so that when fixed pixel positions, may reduce encountered intermediate gradation display process of bleeding problems.

[0473] 在根据下述实施例的液晶显示器中,如图35B所示,在列方向两相邻像素(第η行和第(η+1)行)公用第η行像素的子像素电极18b和第n+1行像素的子像素电极18a之间设置的公共CS总线CSBL,以便将存储电容反电压(振荡电压)供给子像素的辅助电容。 [0473] In the liquid crystal display according to the embodiment of the following embodiment, shown in Figure 35B, two adjacent pixels in the column direction (first row and [eta] (η + 1) row) of [eta] common row pixels subpixel electrode 18b a common CS bus line CSBL and between the n + electrodes 18a 1 sub-pixel row of pixels disposed to the storage capacitor counter voltage (oscillating voltage) supplied to the sub-pixel storage capacitor. 公共CS总线CSBL也起到黑矩阵的作用,以阻挡第η行和第(η+1)行像素之间的光通过。 A common CS bus line CSBL also functions as a black matrix, [eta] to block the first row and the (η + 1) between the rows of pixels by light. 公共CS总线CSBL这样设置:即,经过绝缘膜部分交迭子像素电极18a和18b。 A common CS bus line CSBL set as follows: That is, after the insulating film partially overlap subpixel electrodes 18a and 18b.

[0474] 在根据下面引作示例的实施例的液晶显示器中,当施加到CS总线的振荡电压振荡周期长于水平扫描周期并且电绝缘CS干线数量为L(L是偶数)时,施加到CS总线的振荡电压振荡周期可以设定为一个水平扫描周期(K是正整数)的2*K*L倍。 [0474] In the following cited as an example of a liquid crystal display of the embodiment, when applied to the oscillating voltage oscillation period of the CS bus line is longer than the horizontal scanning period and the number of electrically insulating CS trunks is L (L is an even number) is applied to the CS bus line the oscillation period of oscillating voltage may be set to one horizontal scanning period (K is a positive integer) times 2 * K * L. S卩,尽管根据本发明第三方面实施例的液晶显示器允许振荡电压的振荡周期仅设定到L倍,但是根据本发明第四方面实施例的液晶显示器具有让振荡周期进一步通过系数2*K增加的优点,其中K不取决于电绝缘CS干线的数量。 S Jie, although a liquid crystal display according to the third aspect of the embodiment of the present invention allows for the oscillation period of the oscillation voltage is set only to L times, according to a fourth aspect of the embodiments of the present invention, a liquid crystal display having the oscillation period so that the coefficient a further 2 * K an additional advantage, where K does not depend on the number of electrical insulation CS trunk. K是取决于单个电绝缘CS干线和CS总线之间连接图案的参数,并等于连接连续CS总线中的公共CS干线的CS总线数(电等效CS总线)的1/2,CS总线构成连接CS干线的一个周期。 K is a parameter depending on the connection patterns between the CS main lines and a single electrical insulating CS bus line, and connecting the CS bus number equal to the common CS trunk CS bus continuously (electrically equivalent CS bus) 1/2, CS bus line connector configuration CS trunk of a cycle. [0475] 根据本发明实施例的液晶显示器的多像素驱动将每个像素分成两个子像素,将不同的振荡电压(存储电容反电压)供给连接各个子像素的辅助电容,因此获得亮子像素和暗子像素。 [0475] The multi-pixel liquid crystal display according to an embodiment of the present invention, the drive of each pixel is divided into two sub-pixels, a different oscillating voltages (storage capacitor counter voltage) supply connecting the storage capacitor of each sub-pixel, thus obtaining bright sub-pixels and dark sub-pixels. 例如,如果TFT关闭后振荡电压的第一变化是电压升高,则出现亮子像素,相反,如果TFT关闭后振荡电压的第一变化是电压降低,则出现暗子像素。 For example, if after a first change of the oscillating voltage TFT off voltage is increased, the bright sub-pixel occurs, on the contrary, if the oscillation of the first change in the voltage after the TFT is turned off voltage is lowered, a dark sub-pixel occurs. 因此,如果用于在TFT关闭后振荡电压应该升高的子像素的CS总线连接到公共CS干线上,而用于在TFT关闭后振荡电压应该降低的子像素的CS总线就连接到另一公共CS干线上,则可能减少CS干线数量。 Thus, if the sub-pixel of the oscillating voltage after the TFT-off should be elevated to a common CS bus line CS main lines, and the sub-pixel of the oscillating voltage after the TFT-off should be reduced even to the other common bus line CS the CS trunk, it may reduce the number of CS trunk. K是表示通过CS总线和CS干线之间连接图案增加周期效果的参数。 K is a parameter to increase the effect of the period between the CS bus line and the CS via trunk connection pattern.

[0476] 通过增加K值,可能相应地增加振荡电压。 [0476] By increasing the value of K, may increase the oscillating voltage accordingly. 但是,优选K值不太大。 Preferably, however, the value of K is not too large. 下面将描述理由。 The following reasons will be described.

[0477] K值的增大增加了连接公共CS干线的子像素数。 Increasing the [0477] K value increases the number of sub-pixels connected to a common CS trunk. 它们连接不同的TFT,其以不同的间隔(1H的倍数)关闭。 They connect different TFT, which is turned off at different intervals (multiples of 1H). 因此,连接到公共CS干线上以增加(或减少)子像素TFT关闭后的第一时间的子像素振荡电压所需的时间,不同于连接到公共CS干线上以增加(或减少)子像素TFT关闭后的第一时间的另一子像素振荡电压所需的时间。 Thus, connected to a common CS trunk to increase (or decrease) the time required for the oscillating voltage of the first sub-pixel a sub-pixel after the time of the TFT-off, unlike connected to a common CS trunk to increase (or decrease) the sub-pixel TFT the time required for the oscillating voltage of another pixel subset of the first time after the closing. 这个时间差随K值的增加而增加,即,随连接到公共CS干线上的CS总线数量的增加而增加。 This time difference increases with increasing K value, i.e., to increase the bus with the number of connections on the common CS trunk CS increases. 这会造成线性亮度不规则的视觉。 This results in a linear brightness irregularities of vision. 为了防止这种亮度不规则,用经验法优选时间差不大于扫描线数(像素行数)的5%。 To prevent such brightness irregularities, preferably the time difference with the empirical method is no greater than the number of scanning lines (pixel rows) of 5%. 例如,在XGA情形,优选K值设定成时间差不大于768行的5%或不大于38H。 For example, in the case of XGA, preferably the value of K is set to a time difference of less than 5% of 768 rows or not more than 38H. 相同地,振荡电压周期的较低限度应该参照图28等来设定,这样不会产生由于波形钝化而造成的亮度不规则。 Similarly, the lower limit of the oscillation voltage period should be set with reference to FIG. 28 and the like, so that no brightness irregularities due to waveform rounding caused. 例如,在45英寸XGA显示器的情形,如果振荡周期是12H或更大,则没有波形钝化的问题。 For example, in the case of XGA display of 45 inches, if the oscillation period is 12H or more, there is no problem in waveform rounding. 因此,在45英寸液晶显示器的情形,如果K设定为I或2,L设定为6,8,10,或12,振荡电压的周期设定在12H-48H之内,则可能实现没有亮度不规则的高质量显示。 Thus, in the case of 45 inches liquid crystal display, if K is set to I or 2, L is set to 8, 10, or 12, in the period of the oscillation voltage is set within 12H-48H, the luminance is not possible to achieve irregular high-quality display. 相同地,考虑振荡电压电源(供给存储电容反电极的驱动电源)数,电绝缘CS干线数L应该规定板(TFT衬底)上等的布线。 Similarly, consider the oscillating voltage source (drive power supply storage capacitor counter electrode) number, the number L of electrically insulating CS main lines to be a predetermined upper wiring board (TFT substrate).

[0478] 下面将描述根据本发明第四方面实施例的液晶显示器及其驱动方法,在引用示例中,K = I,L = 4,6,8,10,或12,在实例中,K = 2,L = 4或6。 [0478] The following liquid crystal display and a driving method according to the fourth aspect of the embodiment of the present invention is described in the cited example, K = I, L = 4,6,8,10, or 12, in the example, K = 2, L = 4 or 6. 为了避免重复前面实施例已经描述的内容,下面的描述集中在CS总线和CS干线之间的布局。 In order to avoid repeated from the previous embodiments have been described, the following description focuses on the layout between CS main lines and CS bus.

[0479] [K= 1,L = 4,振荡周期=8H] [0479] [K = 1, L = 4, oscillation period = 8H]

[0480] 根据本发明液晶显示器的矩阵结构(CS总线的连接图案)如图37所示,用于驱动液晶显示器的信号波形如图38所示。 [0480] FIG The matrix structure of the liquid crystal display of the invention (CS bus line connection patterns) 37, a signal waveform for driving the liquid crystal display 38 as shown in FIG. 而且,用于图37的连接图案在表7中示出。 Further, the connection patterns used in FIG. 37 are shown in Table 7. 用图37所示的矩阵结构,因为使用如38所示的定时将振荡电压施加到CS总线上,因此实现了图35A所示的驱动状态。 Matrix structure shown in FIG. 37, since the timing as shown in the oscillating voltage 38 is applied to the CS bus line, thus achieving a driving state shown in FIG. 35A.

[0481] 在图37中,每个CS总线连接到设置在图左、右两端的所有四个CS干线上。 [0481] In FIG. 37, each connected to a CS bus line on FIG left and right ends of all the four CS trunks. 因此,有四组电绝缘CS总线,因此L = 4。 Thus, four sets of the CS bus line electrically insulating, so L = 4. 而且,在图37中,连接CS总线和CS干线之间的图案有某些规则,即,在图中每8个CS总线重复相同的图案。 Further, in FIG. 37, the connection patterns between the CS bus lines and CS trunks have certain rules, i.e., in FIG. 8 each CS bus repeating the same pattern. 因此,K = I ( = 8/(2L))。 Thus, K = I (= 8 / (2L)).
