涉及一种能改善色偏(color shift)现象之液晶显示面板及其像素结构。 It relates to an improved liquid crystal color shift (color shift) phenomenon and the pixel structure of the display panel. 背景技术 Background technique

薄膜晶体管液晶显示器(TFT-LCD)由于具有高画质、空间利用效率佳、 低消耗功率、无辐射等优越特性,因而已逐渐成为市场之主流。 A thin film transistor liquid crystal display (TFT-LCD) Because of the high image quality, excellent space utilization efficiency, low power consumption, no radiation superior characteristics, and thus has gradually become the mainstream market. 目前,市场对于液晶显示器的性能要求是朝向高对比(High Contrast Ratio)、 快速反应与广视角等特性。 Currently, the market for liquid crystal display performance requirements toward the high contrast (High Contrast Ratio), wide viewing angle and rapid response characteristics. 目前能够达成广视角要求的技术,例如有多域垂直配向(Multi-domain Vertically Alignment, MVA)薄膜晶体管液晶显示器、多土或水平酉己向(Multi—domain Horizontal Alignment, MHA)薄膜晶体管液晶显示器等等。 Now possible to achieve technical wide viewing angle requirements, such as how MVA (Multi-domain Vertically Alignment, MVA) a thin film transistor liquid crystal display, a multi-earth or horizontal unitary hexyl to (Multi-domain Horizontal Alignment, MHA) a thin film transistor liquid crystal display, Wait.

目前已经有人提出解决上述色偏的方法,其中一种方法是在单一像素结构内形成两种液晶电容,使单一像素结构内因为不同的液晶电容而产生不同的液晶分子排列。 A method has now been proposed to solve the above-described color shift, wherein the method is the formation of two liquid crystal pixel capacitance within a single structure, the inner structure of a single pixel because of the different capacitances of the liquid crystal of the liquid crystal molecules produce different arrangement. 虽然此种方式可以改善色偏现象,但是此种方式的缺点是最终辉度不足且对比较差。 Although this way can improve the color shift, but the disadvantage of this approach is the lack of ultimate brightness and poor contrast.

另一种方法是在单一像素结构内形成两条扫描线、两个晶体管以及两个独立的电容器,以使单一像素结构内因为两电容器不同的储存电容而产 Another method is to form two scanning lines in a single pixel structure, two separate transistors and two capacitors, so that because of the different capacitances of the capacitors storage capacity within a single pixel structure

5生不同的液晶分子排列。 5 different green liquid crystal molecules. 虽然此种方式可以解决色偏现象且改善了最终辉度不足之问题,但是因为需要在单一像素结构内形成两条扫描线、两个晶体管以及两个独立的电容器,因此必须另外订制合适的驱动电路,而且还会使开口率下降。 Although this embodiment can solve the color shift and improve the shortcomings of the final luminance problem, but because of the need two scanning lines are formed within a single pixel structure, two separate transistors and two capacitors, it is necessary to order additional suitable driving circuit, but also the aperture ratio decrease.

具体实施方式 detailed description

图1是依照本发明之一较佳实施例的一种像素结构的俯视示意图。 FIG 1 is a schematic top view of a pixel structure in accordance with one embodiment of the present invention is preferred. Map

2是沿着图1之I-工'的剖面示意图。 2 is a sectional view taken along the I- FIG station 1 '. 请同时参照图1以及图2,本发明之像素结构10包括扫描线102、数据线104、第一薄膜晶体管106、第二薄膜晶体管108、第一像素电极110以及第二像素电极112。 Please refer to FIG. 1 and FIG. 2, the pixel structure 10 of the present invention includes a scan line 102, data line 104, a first thin film transistor 106, a second thin film transistor 108, a first pixel electrode 110 and the second pixel electrode 112.

扫描线102以及数据线104是设置于基板100上,且扫描线102与数据线104会与第一薄膜晶体管106与第二薄膜晶体管108电连接。 Scan lines 102 and the data line 104 is disposed on the substrate 100, and the scan line 102 and data line 104 will be the first thin film transistor 106 is electrically connected to the second thin film transistor 108. 第一薄膜晶体管106包括栅极(即扫描线102的一部分)、覆盖在栅极上的栅绝缘 A first thin film transistor includes a gate 106 (i.e., a portion 102 of the scanning line), the gate electrode overlying the gate insulating

9层103、设置于栅绝缘层103上的通道层132以及位于通道层132上的漏极136a与源极136b。 9 layer 103 is disposed on the channel layer on the gate insulating layer 132 and 103 located on the drain electrode 136a and the source electrode 132 channel layer 136b. 第二薄膜晶体管108包括栅极(即扫描线102的一部分)、覆盖在栅极上的栅绝缘层103、设置于栅绝缘层103上的通道层134 以及位于通道层134上的漏极138a与源极138b。 A second thin film transistor includes a gate 108 (i.e., the scan line portion 102), covering the gate insulating layer on the gate electrode 103, channel layer 134 is provided on the gate insulating layer 103 and the drain electrode located on the channel layer 138a and 134 The source 138b.

因此,第一薄膜晶体管106以及第二薄膜晶体管108都是形成在扫描线102上,并且以扫描线102的一部分作为其栅极。 Accordingly, the first thin film transistor 106 and a second thin film transistor 108 are formed on the scan line 102, and a portion of the scanning line 102 as its gate. 而第一薄膜晶体管106 的源极136b以及第二薄膜晶体管108的源极138b都是连接至数据线104。 While a source electrode 136b of the thin film transistor 106 and the source of the second thin film transistor 108 138b are connected to the data line 104. 因此两薄膜晶体管106、 108是共同的电连接至相同的扫描线102以及相同的数据线104。 Thus 106, 108 is common to two thin film transistors electrically connected to the same scan line 102 and data line 104 of the same.

特别是,第一薄膜晶体管106具有第一元件宽/长比,而第二薄膜晶体管108具有第二元件宽/长比。 In particular, the first thin film transistor element 106 having a first width / length ratio, and the second thin film transistor element 108 having a second width / length ratio. 在一较佳实施例中,第一薄膜晶体管106 的第一元件宽/长比大于第二薄膜晶体管108的第二元件宽/长比。 In a preferred embodiment, the first member 106 of the first thin film transistor width / length ratio is larger than a second element 108 of the second thin film transistor width / length ratio. 较详细的说明是,第一薄膜晶体管106的元件长度是L1且元件宽度是W1,而第二薄膜晶体管108的元件长度是L2且元件宽度是W2,而第一元件宽/长比(W1/L1)会大于第二元见宽/长比(W2/L2)。 A more detailed explanation, the length of the first element is a thin film transistor 106 is L1 and the element width W1, and the length of the second member 108 is a thin film transistor and the element L2 is a width W2, and the first member width / length ratio (W1 / L1) greater than the second element will see the width / length ratio (W2 / L2).

另外,在第一薄膜晶体管106以及第二薄膜晶体管108上还包括覆盖有保护层109。 Further, on the first film and the second thin film transistor 106 comprises a transistor 108 further covered with a protective layer 109. 第一像素电极110以及第二像素电极112是形成在保护层109表面上。 The first pixel electrode 110 and the second pixel electrode 112 is formed on the surface of the protective layer 109. 第一像素电极110会与第一薄膜晶体管106电连接,其例如是透过接触窗111而彼此电连接。 The first pixel electrode 110 is electrically connected to the first thin film transistor 106, which, for example, through a contact hole 111 are electrically connected to each other. 第二像素电极U2会与第二薄膜晶体管108电连接,其例如是透过接触窗113而彼此电连接。 U2 will be the second pixel electrode is electrically connected to the second thin film transistor 108, which is for example 113 electrically connected to each other through the contact hole. 在一实施例中,第一像素电极110与第二像素电极112分别是位于数据线104的两侧,且两像素电极110、 112彼此分离开来。 In one embodiment, the first pixel electrode 110 and the second pixel electrode 112 are located on both sides of the data line 104, and the pixel electrodes 110, 112 separated from one another. 第一像素电极110与第二像素电极112 例如分别是透明电极。 The first pixel electrode 110 and the second pixel electrode 112 is a transparent electrode, respectively, for example. 当然,本发明并不限定两像素电极110、 112 —定是透明电极,其亦可以是反射电极,或者是其中之一为透明电极而另一为反射电极。 Of course, the present invention is not limited to the pixel electrodes 110 112 - given the transparent electrode, it may also be a reflective electrode or a transparent electrode is one and the other is a reflective electrode.

依据本发明之一较佳实施例,此像素结构IO还包括共用电极114,其设置于第一像素电极110以及第二像素电极112之底下,共用电极114会分别与第一像素电极110以及第二像素电极112产生电容耦合,以作为像素结构IO的储存电容。 One embodiment of the present invention according to a preferred embodiment, IO pixel structure further includes a common electrode 114, which is disposed on the first pixel electrode 110 and the bottom 112 of the second pixel electrode, the common electrode 114 respectively in the first and the second pixel electrode 110 two capacitively coupled to the pixel electrode 112, as the pixel structure of the storage capacitor IO.

特别是,由于第一薄膜晶体管106以及第二薄膜晶体管108的元件宽/长比不相同,因此当扫描线102与数据线104驱动像素结构10时,输入第一像素电极110以及第二像素电极112的电压会不相同。 In particular, since the first member 106 and a second thin film transistor 108 thin-film transistor width / length ratio is not the same, so that when the scanning lines 10 and the data line 102 drives the pixel structure 104, a first input pixel electrode 110 and the second pixel electrode 112 are not the same voltage. 因此,本发明因设计第一薄膜晶体管106以及第二薄膜晶体管108的元件宽/长比不相同,因而能够在以同一扫描线102以及数据线104驱动的情况下于单一像素结构10中产生两种像素电极电压。 Accordingly, the present invention is due to the design of the first element 106 and a second thin film transistor 108 thin-film transistor width / length ratio is not the same, it is possible to generate a single pixel in two structures 10 and in the case of the data line 104 to drive the scanning lines 102 at the same seed pixel electrode voltage.

而若是将此种像素结构应用在液晶显示面板中时,将可以使得位于第一像素电极110上方的液晶分子以及位于第二像素电极112上方的液晶分子有不同的排列方式。 And if the application of such a pixel structure when the liquid crystal display panel, the liquid crystal molecules will be located above the first pixel of the liquid crystal molecules in the second pixel electrode 110 and the upper electrode 112 have different arrangements. 因此,本发明可以使得单一像素结构10中的液晶分子有两种不同的排列方式,如此可以解决液晶显示面板会有色偏的问题。 Accordingly, the present invention may be such that a single pixel structure of the liquid crystal molecules 10 are arranged in two different ways, such liquid crystal display panel can be solved the problem of color shift.

图3是依照本发明之另一较佳实施例的一种像素结构的俯视示意图。 FIG 3 is a schematic top view of a pixel structure in accordance with another preferred embodiment of the present invention. 图3所示的像素结构是一种应用于广视角液晶显示面板的像素结构20,其与图1之像素结构10类似,不同之处在于其于第一像素电极110以及第二像素电极112内都还包括形成有配向狭缝图案116。 Pixel structure shown in FIG 3 is applied to a wide viewing angle liquid crystal display pixel structure 20, which is similar to the pixel structure of FIG. 110, except that it in the second pixel 110 and the first pixel electrode 112 there were further comprising forming an alignment slit pattern 116. 而图3所示的配向狭缝图案116是一种多域水平配向式的配向图案设计,其例如是由多个平行于扫描线102的狭缝所构成。 And illustrated in Figure 3 with the slit pattern 116 is a multi-domain alignment type horizontal alignment pattern design, for example, by a plurality of slits parallel to the scanning line 102 is formed. 但,本发明并不限定配向狭缝图案116的布置方式与形状,其亦可以是多域垂直配向式的配向图案,或是其它种配向图案变化。 However, with the present invention is not limited to the arrangement and shape of the slit pattern 116, which may also be a multi-domain vertical alignment with the pattern type is changed to a pattern, or with other species.

若是将本发明之像素结构20应用于液晶显示面板中,除了可以达到广视角的目的之外,还可以消除传统广视角液晶显示器存在高色偏的问题。 If the pixel structure of the present invention is applied to the liquid crystal display panel 20, in addition to a wide viewing angle can be attained, but also eliminates the presence of high color shift problem of the conventional liquid crystal display of a wide viewing angle. 另外,由于本发明是利用薄膜晶体管之元件宽/长比之不同,而使单一像素结构具有不同的像素电极电压,此种方式不会造成最终辉度不足以及对比较差之问题。 Further, since the present invention is the use of the thin film transistor width / length ratio of the different, the structure of a single pixel having a different pixel electrode voltage, in this way does not cause lack of final brightness and poor contrast problem. 此外,本发明在单一像素结构内仅使用数据线、扫描线以及电容电极,因此其驱动电路的设计与一般像素结构并无不同,因而不需要另外设计特殊的驱动电路。 Further, the present invention uses only pixel structure in a single data line, a scanning line and a capacitor electrode, the design and general configuration of the driving circuit of the pixel is not different, so no further special design of the driving circuit. 而且,因为单一像素结构内仅使用数据线、扫描线以及电容电极,因此不会使开口率明显降低。 Moreover, because only the data lines, scanning lines, and a capacitor electrode structure within a single pixel, it will not significantly decrease the aperture ratio.
