阵列基板及显示装置 An array substrate and a display device

技术领域 FIELD

[0001] 本发明属于显示技术领域,具体涉及一种阵列基板及显示装置。 [0001] The present invention belongs to the field of display technology, particularly relates to an array substrate and a display device.

背景技术 Background technique

[0002] 随着显示器制造技术的发展,液晶显示器技术发展迅速,已经逐渐取代了传统的显像管显示器而成为未来平板显示器的主流。 [0002] With the development of display manufacturing technology, LCD technology has developed rapidly, has gradually replaced traditional CRT monitors and flat panel displays become the mainstream. 在液晶显示器技术领域中,TFT-1XD(ThinFilm Transistor Liquid Crystal Display,薄膜晶体管液晶显示器)以其大尺寸、高度集成、功能强大、工艺灵活、低成本等优势而广泛应用于电视机、电脑、手机等领域。 In the art of liquid crystal displays, TFT-1XD (ThinFilm Transistor Liquid Crystal Display, TFT-LCD) its large size, highly integrated, powerful and flexible process, the advantages of low cost and widely used in televisions, computers, mobile phones and other fields.

[0003] 其中,如ADS模式(高级超维场转换模式)的显示面板通过同一平面内狭缝电极边缘所产生的电场以及狭缝电极层与板状电极层间产生的电场形成多维电场,使液晶盒内狭缝电极间、电极正上方所有取向液晶分子都能够产生旋转,从而提高了液晶工作效率并增大了透光效率。 [0003] wherein the electric field between the electrode layer and the plate and a slit electrode pattern layer, such as ADS (Advanced Super Dimensional conversion mode) in the display panel produced by the edges of slit electrodes formed on the same plane to produce a multi-dimensional field, so that between the slit electrode liquid crystal cell, the positive electrode over all orientations of the liquid crystal molecules are able to produce rotation, thereby improving the work efficiency of the liquid crystal and increases light transmittance. ADS模式的显示面板是由阵列基板(即TFT基板)和彩膜基板(即CF基板)对盒组装并灌注液晶制成。 The ADS mode of the display panel is made of an array substrate (TFT substrate) and a color filter substrate (i.e., the CF substrate) of the cartridge assembly and filling of the liquid crystal. 一般的,如图1所示,所述阵列基板上形成有栅线2 (即扫描线)的图形、数据线I (即信号线)的图形、薄膜晶体管5的图形、过孔的图形以及像素电极(即显示电极)的图形和公共电极的图形,其中,多根栅线2及多根数据线I交叉定义若干个像素区A,其中,在像素电极6和公共电极3 —个为板状电极,一个为狭缝电极,且狭缝电极位于板状电极上方(本发明中以像素电极6为板状电极,公共电极3为狭缝电极为例进行描述)。 Generally, as shown in FIG. 1, a gate line 2 (i.e., scan line) pattern formed on the array substrate, a data line pattern I (i.e., signal lines), graphics, via a thin film transistor and a pixel pattern 5 electrode pattern and the common electrode pattern (i.e., display electrodes), wherein the plurality of gate lines 2 and a plurality of data lines intersecting I define a plurality of pixel region a, wherein the pixel electrode and the common electrode 6 3 - is a plate-like electrode, a slit electrode, and a plate-like slit electrode positioned over the electrode (the pixel electrode to the present invention is a plate electrode 6, the common electrode is a slit electrode 3 will be described as an example). 需要说明的是,在数据线I所在层与像素电极6所层之间设置有第一绝缘层11 (需要说明的是,该第一绝缘层11在有的阵列基板中也是可以没有的),在像素电极6所在层与公共电极3所在层之间设置有第二绝缘层12。 Incidentally, the data line I is located between the layer 6 and the pixel electrode layer is provided with a first insulating layer 11 (Incidentally, the first insulating layer 11 in the array substrate and some are not possible), layer located between the layer where the pixel electrode 3 and the common electrode 6 is provided with a second insulating layer 12. 所述彩膜基板上形成有黑矩阵(BM)图形、RGB图形等。 The formed black matrix (BM) pattern, RGB color filter pattern on the other substrate.

[0004] 如图1、2所示,像素电极6的图形一般与数据线I的图形相隔一段距离,因此像素电极6与数据线I之间、公共电极3与数据线I之间会形成电场。 [0004] As shown, the general pattern of the pixel electrode 6 and the data line pattern at a distance of 1,2 I, and therefore between the pixel electrode 6 and the data line I, the electric field formed between the common electrode 3 and the data line I . 但是像素电极6与数据线I之间的距离很小,故产生的电场的影响也很小,主要是数据线I与狭缝状的公共电极3之间产生的电场会导致每根数据线I的上方及两侧的液晶分子无法有效偏转,造成漏光的冋题。 But the distance between the pixel electrode 6 and the data line I is very small, so the impact of the electric field is small, the electric field is mainly generated between the data line I and the slit-shaped common electrode leads to each data line I the above and on both sides of the liquid crystal molecules can not effectively deflect, causing light leakage problem Jiong.

[0005] 为了解决上述问题,现有技术中通常在形成公共电极3的同时在与数据线I所对应的位置形成屏蔽电极4 (该屏蔽电极4实质也是公共电极3的一部分,只不过由于设置在数据线I上方用于屏蔽数据线1,故称之为屏蔽电极4),该屏蔽电极4与公共电极3接同样的信号,用于屏蔽数据线1,以防止数据线I与共公共电极3之间形成电场,但同时会导致屏蔽电极4与数据线I之间形成较大的电容,故数据线I上的数据电压信号将会对屏蔽电极4上的信号产生影响,进而造成公共电极3上的公共电极3信号受到干扰,且波动很大,产生Greenish flicker以及负载偏大等不良。 While [0005] In order to solve the above problems, the prior art is generally a common electrode 3 is formed shield electrode portion 4 (the shield electrode 4 is a common electrode 3 of the substance at a position corresponding to the data line I, except that since the I over the data lines for shielding the data line 1, it is called the shield electrode 4), the same signal electrode 4 and the common electrode connected to the shield 3 for shielding the data line 1, to prevent the common data line I and common electrode 3 it is formed between the electric field, but will also result in formation of a large capacitance between the shielding electrode 4 and the data line I, it is the data signal voltage on the data line I will affect the signal on the shield electrode 4, thereby causing the common electrode 3 the common electrode 3 on the interference signal, and volatile, adverse Greenish flicker and other larger load. 而且同时,由于屏蔽电极4和公共电极3是相同材料的,也就说屏蔽电极4是透光的,因此需要在彩膜基板上与屏蔽电极4对应的位置形成黑矩阵,而且彩膜基板和阵列基板在对盒时会出现不可避免的偏差,因此所形成的黑矩阵的宽度较宽,从而造成显示面板的开口率下降。 Further Meanwhile, since the shield electrode 4 and the common electrode 3 are the same material, said shield electrode 4 is also transparent, it is necessary on the color filter substrate corresponding to the position of the shielding electrode 4 is formed a black matrix and the color filter substrate and in the array substrate of the cartridge will be unavoidable deviation, the width of the black matrix is ​​formed wider, resulting in decrease in the aperture ratio of the display panel.

[0030] 为使本领域技术人员更好地理解本发明的技术方案,下面结合附图和具体实施方式对本发明作进一步详细描述。 [0030] to enable those skilled in the art better understand the technical solutions of the present invention, the following accompanying drawings and specific embodiments of the present invention will be described in further detail.

[0031] 一种阵列基板,其包括:基底,以及依次设置在基底上的数据线、第一电极、第二电极,以及设置数据线上方的屏蔽电极;所述屏蔽电极内形成有与所述数据线位置对应的第一开口,所述屏蔽电极与所述第二电极同层设置,且两者之间无电场或形成弱电场。 [0031] An array substrate, comprising: a substrate, and the substrate are sequentially disposed on the data line, a first electrode, a second electrode, disposed above the data line and a shield electrode; formed with the inner shield electrode opening a first data line corresponding to the position of the shielding electrode and the second electrode in the same layer, and no electric field or a weak electric field is formed therebetween.

[0033] 实施例1: [0033] Example 1:

[0034] 如图3和4所示,本实施例提供一种阵列基板,其包括交叉且绝缘设置的多条栅线2和多条数据线I (其中栅线2所在层与数据线I所在层之间设置有第三绝缘层13),在栅线2和数据线I的交叉位置限定出像素区,在每个像素区内均设置有像素电极6和公共电极3,其中,像素电极6为板状电极,公共电极3为设于像素电极6上方的狭缝电极,需要说明的是,在数据线I所在层与像素电极6所层之间设置有第一绝缘层11 (该第一绝缘层11在有的阵列基板中也是可以没有的),在像素电极6所在层与公共电极3所在层之间设置有第二绝缘层12。 [0034] As shown in FIGS. 3 and 4, the present embodiment provides an array substrate comprising an insulating and crossing the plurality of gate lines arranged two data lines and a plurality of I (2 wherein the layer where the gate lines and data lines where I a third insulating layer disposed between the layer 13), defining at the intersection position of the gate lines 2 and data lines of the pixel region I, provided with a pixel electrode 3 and the common electrode 6 in each pixel region, wherein the pixel electrode 6 is a plate electrode, the common electrode 3 is provided on the slit electrode over the pixel electrode 6, to be noted that, between the data line layer 6 and the pixel electrode layer where I is provided with a first insulating layer 11 (the first some insulating layer in the array substrate 11 is not possible), the second insulating layer 12 is provided between a layer where the layer where the pixel electrode 3 and the common electrode 6. 特别的是,在本实施例的中的数据线I的正上方设置有与所述公共电极3同层设置的屏蔽电极4,屏蔽电极4与公共电极3之间无电场或形成弱电场,且该屏蔽电极 In particular, the shield is provided with three electrodes disposed in the same layer of the common electrode directly above the data line I of the present embodiment 4, the shielding electrode 4 and no electric field is formed between the common electrode or a weak electric field, and the shield electrode

4内形成有与数据线I位置对应的第一开口4-1。 4 has a first opening formed in the data line I and 4-1 corresponding to the position.

[0035] 由于本实施例阵列基板中的数据线I的正上方设置有屏蔽电极4,因此可以避免液晶面板中数据线I与公共电极3之间产生电场,导致数据线I两侧的液晶无法有效旋转的问题,同时在屏蔽电极4与数据线I对应的问题设置有第一开口4-1,因此可以减小数据线I与屏蔽电极4的有效正对面积,从而减小数据线I与屏蔽电极4之间所产生的寄生电容,进而使得大大减小屏蔽电极4对数据线I上的负载以及对公共电极3上的公共电压信号的影响。 [0035] Since the data line immediately above the array substrate of the present embodiment is provided with a shield electrode I 4, thus creating between the liquid crystal panel 3 can be avoided and the common data line I electric field, causing the liquid crystal can not be on both sides of the data line I rotating a valid issue, while 4-1 is provided with a first opening, it is possible to reduce the data line I and the shield electrode active alignment area 4, thereby reducing the data line I and the shielding electrode 4 issue data corresponding to the line I parasitic capacitance generated between the shield electrode 4, and further such that the load is greatly reduced and the effect on the common voltage signal on the common electrode 3 on the data line 4 to the shield electrode I.

[0036] 由于屏蔽电极4与公共电极3之间无电场或者形成弱电场,因此可以优选地,将公共电极3线与屏蔽电极4连接同一信号线,也就是说在公共电极3和屏蔽电极4上施加的电压相同,从而可以使得布线简单且容易实现。 [0036] Since the shield electrode is formed without a weak electric field or an electric field between the common electrode 3 and 4, it can be preferable that the wire 4 is connected to the common electrode 3 and the shield electrode of the same signal line, i.e. the common electrode 3 and the shield electrode 4 the same applied voltage, so that the wiring can be simple and easy to implement.

[0037] 结合图5所示,优选地,在本实施例中的数据线I下方设置有遮光条7 ;该遮光条7与屏蔽电极4的在基底上的投影区域完全重合,以防止来自背光源的光从屏蔽电极4所在位置透过,导致显示面板出现漏光,致使显示面板所显示的画面不良的问题。 [0037] in conjunction with FIG. 5, preferably under the data line I in the present embodiment is provided with a light-shielding strip 7; the light-shielding strip 7 and the shield electrode projection region on the substrate 4 completely overlap to prevent light from the backlight light from the source location via the shield electrode 4, light leakage occurs resulting in the display panel, failure screen displayed on the panel display cause problems. 同时可以理解的是,由于背光源的光不能阵列基板上与屏蔽电极4所对应的位置透过的,因此需要在彩膜基板上与屏蔽电极4所对应的位置形成黑矩阵,而当阵列基板与彩膜基板对盒时,会出现不可避免的对盒偏差,因此需要将和矩阵的宽度做得较宽,以防止背光源的光透过,但是,由于黑矩阵的宽度增加,势必会降低显示面板的开口率。 It will be appreciated that the same time, because the light is not backlight array substrate corresponding to the position of the electrode 4 through the shield, it is necessary on the color filter substrate corresponding to the position of the electrode 4 forming a black matrix mask, when the array substrate and the color filter substrate of the cartridge, the cartridge will inevitably deviation, it is necessary to be made wider and the width of the matrix to prevent light transmitted through the backlight, however, due to the increased width of the black matrix, is bound to reduce the aperture ratio of the display panel. 而在本实施例将用于防止背光源的光透过屏蔽电极4所在区域的遮光条7设置在阵列基板侧,因此可以省去在彩膜基板上制备与屏蔽电极4位置对应的黑矩阵,从而也不会影响显示面板的开口率。 In the present embodiment, for preventing backlight light passes through light-shielding strip Area shielding electrode 47 provided on the array substrate side, thus prepared may be omitted and the shield electrode 4 corresponding to the position of the black matrix on the color filter substrate, thus it will not affect the aperture ratio of the display panel.

[0038] 需要说明的是,所述遮光条7与所述屏蔽电极4在基底上的投影区域也不一定是完全吻合的,屏蔽电极4的第一开口4-1的大小和遮光条4的宽度都要根据不同的设计要求来进行设计,比如说如果要求寄生电容很小,那屏蔽电极4的第一开口4-1就要比较大;如果要求一般,屏蔽电极4的第一开口4-1的宽度也可以是数据线I的宽度的一半。 [0038] Incidentally, the light-shielding strip 7 and the shielding electrode 4 projection region on the substrate are not necessarily fully in line, a first opening of the shield electrode 4-1 and the light-shielding strip size 4 4 width should be designed according to different design requirements, such as required if the parasitic capacitance is small, and that the shield electrode should first opening of large 4-14; general, if required, the shield electrode of the first opening 4-4 1 may also be a width half the width of the data line I. 而遮光条4的宽度就要根据在固定的第一开口4-1下,以防止数据线I对液晶分子的影响范围,如果影响范围较大,则遮光条4的宽度就要较宽,否则反之。 And light shielding is necessary according to the strip width 4 of a first opening at 4-1 fixed to prevent the data line pair I scope of the liquid crystal molecules, if a large impact range, the light-shielding strip 4 will wider width, or on the contrary.

[0039] 其中,所述遮光条7与所述第二电极之间无电场或者形成弱电场,也就是说遮光条7可以与第二电极上所施加的电压相同或者是所施加的电压相差不大;当然还可以是遮光条7的两端处于悬空,此时遮光条7与第二电极之间也是无电场的。 [0039] wherein said light-shielding strip 7 between the second electrode is formed and no electric field or a weak electric field, i.e. the same as the light-shielding strip 7 may be applied on the second electrode or a voltage difference between the applied voltage is not Great; of course also be the two ends of the light-shielding strip 7 is suspended, when the light-shielding strip 7 is not between the second electrode and the electric field. 之所以如此设置是因为,若遮光条7第二电极之间产生电场同样会造成数据线I两侧的液晶分子无法有效旋转,以造成显示不良的问题;而遮光条7第二电极之间无电场,或仅仅是形成弱电场,此时处于遮光条7上方的液晶分子的旋转则不会受到影响,即使存在一些影响也是很小的,可以忽略不计。 This is so because the setting, if the electric field is generated between the second electrode of the light-shielding strip 7 will also cause the liquid crystal molecules on both sides of the data line I can not be effectively rotated to cause the problem of poor display; and no light-shielding strip 7 between the second electrode electric field, or only a weak electric field is formed, in this case the rotation of the liquid crystal molecules above the light-shielding strip 7 will not be affected, even if there is some impact is very small, negligible.

[0040] 进一步优选地,遮光条7内形成有与所述数据线I位置对应的第二开口4-2,所述第二开口4-2的宽度等于所述数据线I的宽度。 [0040] Further preferably, a second opening 4-2 to the data line corresponding to the position I within the light-shielding strip 7 is formed, the width of the second opening 4-2 is equal to a width of the data line I. 因此,可以有效的避免由于遮光条7与数据线I之间存在正对面积而产生不可避免的寄生电容,导致数据线I上的负载较大,从而导致数据线I上的电压被拉低,造成显示不良的现象。 Thus, it is possible to effectively avoid the presence of the alignment area between the light-shielding strip 7 and the data line I and the unavoidable parasitic capacitances generated, causes the load on the data line I is large, resulting in the voltage on the data line is pulled low I, adverse show phenomenon.

[0041] 更进一步优选地,屏蔽电极4上的第一开口4-1的宽度等于所述第二开口4-2的宽度,也就是第一开口4-1的宽度等于数据线I的宽度,从而可以尽可能避免在屏蔽电极4与数据线I之间产生寄生电容,同时在屏蔽电极4第一开口4-1之外的位置是被遮光条7所遮挡的,因此也不会造成漏光的现象。 [0041] Still further preferably, the width of the first opening of the shield electrode on 4-1 4 4-2 equal to a width of the second opening, the width of which is equal to the width of the first opening of the 4-1 data line I, thereby avoiding as much as possible parasitic capacitance between the data line 4 and the shielding electrode I, while the shield electrode 4 than the first opening position 4-1 is shielded by the light-shielding strip 7 and therefore will not cause light leakage phenomenon.

[0042] 可以理解的是,在阵列基板上是设置有薄膜晶体管5的,优选地,所述遮光条7与所述薄膜晶体管5的栅极同层设置,且材料相同。 [0042] It will be appreciated that, on the array substrate is provided, preferably the thin film transistor 5, the light-shielding strip 7 with the thin film transistor gate electrode layer 5 is provided, and the same material. 也就是说遮光条7可以是与栅极采用一次构图工艺形成的,从而可以节约制备工艺步骤,节约成本,以及提高生产效率。 That is the light-shielding strip 7 may be a patterning process using the gate electrode is formed, which can save manufacturing process steps, cost savings, and increased productivity. 当然,遮光条7也是可以不与栅极同层形成,只要是形成在数据线I下方,能够遮挡背光源的光透过显示面板与屏蔽电极4所对应的区域即可,同时可以理解的是,遮光条7的材料也是可以与栅极材料不同,只要是能够遮光的材料即可。 Of course, also the light-shielding strip 7 may not be formed with the same layer as the gate, as long as it is formed under the data line I, can block light transmission backlight the display panel and the shielding electrode 4 corresponding to the region, to be understood that while , the light-shielding material strip 7 are also possible with different gate material, as long as a material capable of shielding.

[0043] 本实施例所提供的阵列基板,不仅可以缓解现有技术中阵列基板中的屏蔽电极4与数据线I之间存在较大的寄生电容的问题,同时,在阵列基板上设置遮光条7,因此不会出现由于黑矩阵宽度较大而影响显示面板开口率的问题。 [0043] The array substrate according to the present embodiment is provided not only alleviate the problem there is a large parasitic capacitance between the shield electrode array in the prior art substrate 4 and the data line I, at the same time, light-shielding strip is provided on the array substrate 7, problems due to large width of the black matrix to affect the aperture ratio of the display panel and will not appear.

[0045] 本实施例提供一种显示装置,其包括实施例1所述的显示面板,故其性能更好。 [0045] The present embodiment provides a display apparatus comprising a display panel according to Example 1, so the better the performance.
