Description

像素电极及阵列基板 技术领域
本发明涉及一种液晶显示面板技术，特别是一种像素电极及阵列基板。
背景技术
液晶显示器(Liquid Crystal Display，LCD)具有机身薄、省电、无辐射等众多优点，得到了广泛的应用，如：液晶电视、移动电话、个人数字助理(PDA)、数字相机、计算机屏幕或笔记本电脑屏幕等，在平板显示领域中占主导地位。
主动式薄膜晶体管液晶显示器(Thin Film Transistor-LCD，TFT-LCD)是目前主流市场最常见的液晶显示器，按照液晶驱动方式的不同其又可大致分为：扭曲向列(Twisted Nematic，TN)或超扭曲向列(Super Twisted Nematic，STN)型，平面转换(In-Plane Switching，IPS)型、及垂直配向(Vertical Alignment，VA)型。其中VA型液晶显示器相对其他种类的液晶显示器具有极高的对比度，在大尺寸显示，如电视等方面具有非常广的应用。而高垂直配向(High Vertical Alignment，HVA)型是VA模式中一个重要的分支。
通常液晶显示装置包括壳体、设于壳体内的液晶面板及设于壳体内的背光模组(Backlight module)。其中，液晶面板的结构主要是由一薄膜晶体管阵列基板(Thin Film TransistorArray Substrate，TFTArray Substrate)、一彩色滤光片基板(Color Filter Substrate，CF Substrate)、以及配置于两基板间的液晶层(Liquid Crystal Layer)所构成，其工作原理是通过在两片向TFT基板的像素电极和CF基板的公共电极上施加驱动电压来控制液晶层的液晶分子的旋转，将背光模组的光线折射出来产生画面。
在进行配向时，由于各像素电极之间相连导致电压异常，造成液晶光配向异常。在电场建立之初，当电压升高至2.0V左右时，像素电极中间出现畴分割“漩涡”(如图1所示)，正常情况下会慢慢扩散至整个像素电极，但由于阵列基板上的像素电极相连，当像素电极周围边界有电场，且电场的强弱无明显差别时，在连接处也会出现畴分割“漩涡”，畴分割就会受到影响无法完成从而导致配向出现乱畴(漩涡)的现象。
发明内容
为克服现有技术的不足，本发明提供一种像素电极及阵列基板，解决乱畴现象，从而提高穿透率。
本发明提供了一种像素电极，包括将像素电极划分为至少两个电极区域的龙骨电极，每个电极区域内设有多个条状的分支电极，分支电极的两端中的一端与龙骨电极相连，每个电极区域中的分支电极朝相同的方向延伸并且平行设置，在每个电极区域中设有至少一个连接电极，所述连接电极与至少两条分支电极相连。
进一步地，相邻两个电极区域内的分支电极的延伸方向不同。
进一步地，所述龙骨电极设有两根，呈十字形交错设置。
进一步地，还包括矩形的边框电极，所述龙骨电极、分支电极以及连接电极设于边框电极中，龙骨电极的两端与边框电极相连，分支电极的另一端与边框电极相连。
进一步地，所述连接电极与龙骨电极的最近距离大于或等于15um。
进一步地，所述连接电极的长度和宽度为2～10um。
进一步地，所述龙骨电极的宽度大于3um。
进一步地，每个电极区域中的连接电极设有一个，所述连接电极与三条以上的分支电极相连。
进一步地，每个电极区域中的连接电极设有两个以上。
本发明还提供了一种阵列基板，包括所述的像素电极。
本发明与现有技术相比，通过将像素电极分割成至少两个电极区域，并在每个电极区域中设置至少一个连接电极，该连接电极与至少两条分支电极相连，使配向开始加电压时，连接电极处会出现轻微乱畴情况，随着配向电压的加强，借由公共电极使像素电极的周边以及龙骨电极附近的液晶有序偏转，使连接电极周边的液晶挤压，进而带动像素电极内的位于连接电极处的液晶有序偏转，最终达到每个方向完全分割的状态，从而避免乱畴现象，有效提高穿透 率。
