Description

液晶显示面板LCD panel 技术领域Technical field

本发明涉及液晶显示领域，尤其涉及一种液晶显示面板。The invention relates to the field of liquid crystal display, in particular to a liquid crystal display panel.

背景技术Background technique

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。Liquid Crystal Display (LCD) has many advantages such as thin body, power saving, and no radiation, and has been widely used. Such as: LCD TV, mobile phone, personal digital assistant (PDA), digital camera, computer screen or laptop screen, etc.

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。Generally, a liquid crystal display device includes a housing, a liquid crystal panel provided in the housing, and a backlight module (Backlight Module) provided in the housing. Among them, the structure of the liquid crystal panel is mainly composed of a thin film transistor array (Thin Film Transistor Array, TFT Array) substrate, a color filter (Color Filter, CF) substrate, and a liquid crystal layer (Liquid Crystal Layer), its working principle is to control the rotation of the liquid crystal molecules of the liquid crystal layer by applying a driving voltage on two glass substrates, and refract the light from the backlight module to produce a picture. Among them, the CF substrate mainly includes a color photoresist layer used to form colored light through the color resist unit (R/G/B), and a black matrix (Black matrix) used to prevent light leakage at the edge of the pixel. Matrix, BM), and spacers (Photo Spacer, PS), in large-size liquid crystal display panels, usually more than two types of spacers are used, such as the main spacer (Main PS) and auxiliary spacer (Sub PS), so as to play the role of multi-level buffer to prevent the occurrence of various mura or defects.

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。COA (Color-filter on Array) technology is an integrated technology in which the color photoresist layer is directly fabricated on the array substrate, which can effectively solve the problem of light leakage caused by the alignment deviation in the liquid crystal display device alignment process, and Can significantly improve the display aperture ratio. In addition, the technical solution of designing PS on the TFT array substrate (PS on Arry, POA) has been proposed by technical personnel, which can continue to reduce the difficulty of the color film substrate.

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。Peripheral display unevenness (Mura) is one of the most common defects (Issue) in LCD display technology, mostly due to the thickness of the edge box (CELL GAP) caused by unevenness. The design of the non-display area (Dummy area) around the LCD panel (Panel) is different from the center display area (AA area), and there is usually a large difference in total film thickness. Among the COA plus POA technology series products, the total film thickness of the dummy area is often lower than that of the AA area due to the limitation of design and product characteristics, resulting in a lower panel edge box thickness, causing black/reddish peripheral 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。As shown in Figure 1, due to the design/material leveling/process and other reasons, in COA plus POA products, the film thickness of the dummy area 9 on the side of the TFT array substrate 1 is difficult to control to be equivalent to the total film thickness of the AA area 8, which is generally higher than that of AA. Zone 8 is low. When the film thickness of the Dummy zone 9 is too low, it will cause the upper glass substrate 2 to bend (Bending), causing the CELL GAP about 2-3mm at the edge of the AA zone 8 to be low, and it will return to normal when it is higher in the AA zone 8 ( For large-size liquid crystal display panels, the peripheral poor display area of about 5-10mm belongs to this display poor), which results in uneven peripheral display and serious peripheral black/white/reddish phenomena.
