Description

一种像素电极结构及液晶显示面板 技术领域
本发明涉及一种液晶显示技术领域，尤其涉及一种像素电极结构及液晶显示面板。
 背景技术
液晶显示器 (LCD) 是最广泛使用的平板显示器之一，LCD 包括设置有场发生电极诸如像素电极和公共电极的一对面板以及设置在两个面板之间的液晶 (LC) 层。当电压被施加到场发生电极从而在 LC 层中产生电场，该电场决定了液晶层中的 LC 分子的取向，因此而调整入射到液晶层的光的偏振时，LCD 显示图像。
目 前 业 界 发 展 出 一 种 称 为 高 分 子 安 定 化 垂 直 配 向 (Polymer Stabilized Vertical Alignment, PSVA) 的技术，该技术是在液晶材料中掺入适当浓度的单体化合 物 (monomer) 并且震荡均匀。接着，将混合后的液晶材料置于加热器上加温到达等向性 （Isotropy) 状态。当液晶混合物降至室温时，液晶混合物会回到向列型 (nematic) 状态。然后，将液晶混合物注入至液晶盒并施与电压。当施加电压使液晶分子排列稳定时，则使用紫外光或加热的方式让单体化合物进行聚合反应生成聚合物层，由此达到稳定配向的目的。
图 1 所示的是一般 VA 模式液晶显示器常用的像素电极的结构示意图。
如图 1 所示通常的 VA 模式 LCD 的像素电极设计为“米”字型，包含条状的竖直主 干（main trunk）、条状的水平主干、以及分别与水平主干呈一定夹角的条状分支（slit），通常，条状分支与水平主干之间的角度为±45度，±135度。各条状分支与竖直主干和水平主干位于同一平面上。其中竖直主干和水平主干中心垂直相交，所谓的中心垂直相交，即指竖直主干和水平主干相互垂直，垂直相交的中心附近的区域即为该单位像素电极的中心区 域，该竖直主干和水平主干将整个像素（pixel）面积平均分成 4 个区域（domain），每个区域 都由与竖直主干或水平主干呈一定角度的条状分支（slit）平铺组成。如此形成图 1 所示 的关于上下和左右分别镜像对称的“米”字型的电极设计。
图 2 是显示在图 1 所示像素电极结构上施加电压（大约为 0~4V，箭头表示有施加电 压）后的液晶倾倒的示意图。
如图 2 所示，通常所采用的“米”字型的电极结构在通电的情况下，液晶的倒向是由像素电极外侧开始逐渐向像素电极内侧倾倒，倾倒的角度是沿分支方向，4 个区域中，右上区域的液晶倾倒方向为 45 度 ；左上区域的液晶倾倒方向为 135 度 ；左下区域的液晶倾倒方 向为 225 度 ；右下区域的液晶倾倒方向为 315 度。由于左上区域与右上区域的多条两两对称的条状分支是沿着竖直主干中心点向外发散，在施加电压的情况下，左上区域与右上的液晶倒向是由像素电极外侧开始逐渐向像素电极内侧倾倒，倾倒的角度是沿分支方向，此时在竖直主干上与多条相互对称的条状分支相交的两条交线之间的液晶倒向容易处于混乱状态；同理左上区域和左下区域的多条两两对称的条状分支在水平主干上相交的两条交线之间的液晶倒向也容易处于混乱状态，从而使“米”字型像素电极的“十”字支杆上极易产生黑纹，使得该“十”字支杆显示效果不佳。

下面结合附图详细本发明实施例的实现过程。
参见图3，为本发明像素电极结构的第一实施例的结构示意图；
本实施例中的像素电极结构，包括：
条状的水平主干1和条状的竖直主干2，水平主干1与竖直主干2垂直相交；
由水平主干1与竖直主干2垂直相交所分成的四个区域中（如图所示的A、B、C、D四个区域），分别具有与水平主干1与竖直主干2均呈一定角度的多条条状分支3，优选的，多条条状分支3与水平主干1和竖直主干2都呈45度角，当然其他角度也是可行的，例如在B区域内，条状分支3与水平主干1呈60度角，则在A区域内，条状分支3与水平主干1呈120度角，只要A区域和B区域，C区域和D区域中间的条状分支3保持对称即可。其中，区域A和区域B镜像对称，区域C和区域D镜像对称，区域A和区域C镜像对称，区域B和区域D镜像对称，多条条状分支4相对于竖直主干2与水平主干1相交的点向外发散，相邻多条条状分支4之间隔有一条缝隙3.
区域A与区域B内的多条条状分支与水平主干1的水平边缘端相交，形成一条不连续的水平线ab，区域C与区域D内的多条条状分支与水平主干1的水平边缘端相交，形成一条不连续的水平线cd；水平线ab和水平线cd分别位于水平主干1上的水平两端。

区域A与区域C内的多条条状分支与竖直主干2的竖直边缘端相交，形成一条不连续的竖直线ac，区域B与区域D内的多条条状分支与竖直主干2的竖直边缘端相交，形成一条不连续的竖直线bd；竖直线ac和竖直线bd分别位于竖直主干2上的竖直两端。
竖直主干2内设置有狭缝6，狭缝6的延伸方向与竖直主干的延伸方向相同，狭缝6位于竖直线ac与竖直线bd之间。
参照图8为第一实施例像素电极结构施加电压后，液晶分子倒向结构示意图。
当向所述像素电极结构施加电压时，液晶的倒向是由像素电极外侧开始逐渐向像素电极内侧倾倒，倾倒的角度是沿分支方向，位于4个区域内的关于竖直主干2和水平主干1两两对称条状分支被狭缝5和狭缝6分隔开，使多条条状分支与水平主干或竖直主干交线处的液晶倒向是沿分支方向倾倒的，而不是来自于沿分支方向与水平方向或竖直方向两个不同方向的液晶倒向的相互干扰，从而使竖直主干与水平主干上的液晶分子倒向特定方向，不会发生混乱，不易产生黑纹。
图4是本发明的像素电极结构的第二实施例的结构示意图。
本实施例中的像素电极结构，包括：
条状的水平主干1和条状的竖直主干2，，水平主干1与竖直主干2垂直相交；
由水平主干1与竖直主干垂直相交所分成的四个区域中（如图所示的A、B、C、D四个区域），分别具有与水平主干1与竖直主干2均呈一定角度的多条条状分支3，优选的，多条条状分支3与水平主干1和竖直主干2都呈45度角，当然其他角度也是可行的，例如在B区域内，条状分支3与水平主干1呈60度角，则在A区域内，条状分支3与水平主干1呈120度角，只要A区域和B区域，C区域和D区域中间的条状分支3保持对称即可。其中，区域A和区域B镜像对称，区域C和区域D镜像对称，区域A和区域C镜像对称，区域B和区域D镜像对称，多条条状分支4相对于竖直主干2与水平主干1相交的点向外发散，相邻多条条状分支4间隔有一条缝隙3.
区域A与区域C内的多条条状分支与水平主干1的水平两端相交，形成两条不连续的水平线ao、co，区域B与区域D内的多条条状分支与水平主干1的水平两端相交，形成两条不连续的水平线bo、do；水平线ao、bo和水平线co、do分别位于水平主干1上的水平两端。
水平主干1内设置有狭缝7和狭缝8，狭缝7和狭缝8的延伸方向与水平主干1的延伸方向相同，狭缝8位于水平线ao与水平线co之间，狭缝7位于水平线bo与水平线do之间。
区域A与区域B内的多条条状分支与竖直主干2的竖直两端相交，形成两条不连续的竖直线a1o、b1o，区域C与区域D内的多条条状分支与竖直主干2的竖直两端相交，形成两条不连续的竖直线c1o、d1o；竖直线a1o、c1o和竖直线b1o、d1o分别位于竖直主干2上的竖直两端。
竖直主干2内设置有狭缝9和狭缝10，狭缝9和狭缝10的延伸方向与竖直主干的延伸方向相同，缝9位于竖直线a1o与竖直线b1o之间，狭缝10位于竖直线c1o与竖直线d1o之间。
参照图9为第二实施例像素电极结构施加电压后，液晶分子倒向结构示意图。
当向所述像素电极结构施加电压时，液晶的倒向是由像素电极外侧开始逐渐向像素电极内侧倾倒，倾倒的角度是沿分支方向，位于4个区域内的关于竖直主干2和水平主干1两两对称条状分支被狭缝7、狭缝8、狭缝9和狭缝10分隔开，使多条条状分支与水平主干或竖直主干交线处的液晶倒向是沿分支方向倾倒的，而不是来自于沿分支方向与水平方向或竖直方向两个不同方向的液晶倒向的相互干扰，从而使竖直主干与水平主干上的液晶分子倒向特定方向，不会发生混乱，不易产生黑纹。
在图 3、和图 4所示的实施例中，仅仅示出了两种不同的在竖直主干与水平主干内设置狭缝的情况，不难理解的是，对于其它不同的在竖直主干与水平主干内设置狭缝的情况，譬如水平主干与竖直主干内设置3个狭缝，均在本发明保护的范围内，此处不再一一详述。
