Description

液晶显示面板 技术领域
本发明涉及液晶显示领域，尤其涉及一种液晶显示面板。
 背景技术
液晶显示装置（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。
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（Thin Film Transistor Array，TFT Array）基板、一彩色滤光片（Color Filter，CF）基板、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玻璃基板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。其中，CF基板主要包括用于通过色阻单元（R/G/B）形成有色光的彩色光阻层、用于防止像素边缘漏光的黑色矩阵（Black Matrix，BM）、以及用于维持盒厚的隔垫物（Photo Spacer，PS），在大尺寸液晶显示面板中，通常会使用两种类型以上的隔垫物，如在CF基板上设置主隔垫物（Main PS）、及辅助隔垫物（Sub PS），从而起到多级缓冲的作用，以防止各种Mura或者不良的发生。
COA（Color-filter on Array）技术是一种将彩色光阻层直接制作在阵列基板上的一种集成技术，能够有效解决液晶显示装置对盒工艺中因对位偏差造成的漏光等问题，并能显著提升显示开口率。另外，已有技术人员提出将PS设计在TFT阵列基板上（PS on Arry，POA）的技术方案，可继续降低彩膜基板侧的难度。
周边显示不均（Mura）是LCD显示技术中最常见的不良（Issue）之一，多由于边缘盒厚（CELL GAP）不均引起。LCD 面板（Panel）四周的非显示区（Dummy区）跟中心的显示区（AA区）设计不一样，通常存在很大的总膜层厚度差异。其中在COA加 POA技术系列产品中，Dummy区往往由于设计和产品特性的限制，总膜厚较AA区偏低，导致Panel边缘盒厚偏低，引起周边泛黑/偏红等周边Mura。
如图1所示，由于设计/材料流平/制程等原因，COA加POA产品中，TFT阵列基板1侧Dummy区9的膜厚难以控制到跟AA区8总膜厚高度相当，一般较AA区8偏低。当Dummy区9膜厚偏低，就会导致上侧玻璃基板2发生弯曲（Bending），引起AA区8边缘约2-3mm的CELL GAP偏低，在向AA区8内部偏高再回复正常（对于大尺寸的液晶显示面板，约5-10mm的周边不良显示区属于此显示不良），因此导致周边显示不均，形成严重的周边泛黑/泛白/泛红等现象。
