Description

框胶及液晶显示面板 技术领域
本发明涉及显示技术领域，尤其涉及一种框胶及液晶显示面板。
 背景技术
随着显示技术的发展，液晶显示器（Liquid Crystal Display，LCD）等平面显示装置因具有高画质、省电、机身薄及应用范围广等优点，而被广泛的应用于手机、电视、个人数字助理、数字相机、笔记本电脑、台式计算机等各种消费性电子产品，成为显示装置中的主流。。
现有市场上的液晶显示装置大部分为背光型液晶显示器，其包括液晶显示面板及背光模组（backlight module）。液晶显示面板的工作原理是在两片平行的玻璃基板当中放置液晶分子，两片玻璃基板中间有许多垂直和水平的细小电线，通过通电与否来控制液晶分子改变方向，将背光模组的光线折射出来产生画面。
通常液晶显示面板由彩膜基板（CF，Color Filter）、薄膜晶体管基板（TFT，Thin Film Transistor)、夹于彩膜基板与薄膜晶体管基板之间的液晶（LC，Liquid Crystal）及密封胶框（Sealant）组成，其成型工艺一般包括：前段阵列（Array）制程（薄膜、黄光、蚀刻及剥膜）、中段成盒（Cell）制程（TFT基板与CF基板贴合）及后段模组组装制程（驱动IC与印刷电路板压合）。其中，前段Array制程主要是形成TFT基板，以便于控制液晶分子的运动；中段Cell制程主要是在TFT基板与CF基板之间添加液晶；后段模组组装制程主要是驱动IC压合与印刷电路板的整合，进而驱动液晶分子转动，显示图像。
现有的液晶显示面板采用的框胶通常包括胶体材料（Main Seal）、分布于胶体材料中的间隔粒子（Spacer）及分布于胶体材料中的导电金球（Au Ball），一般按照质量比胶体材料：间隔粒子：导电金球=100：1：2混合在一起，这种胶框中包含间隔粒子和导电金球，间隔粒子起到支撑上下基板保持液晶盒厚（Cell Gap）的作用，导电金球起到导通上下电极的作用，液晶显示面板的边缘地形复杂，间隔粒子和导电金球的粒径选型对于其支撑和导电的稳定性影响巨大，对于同时包含间隔粒子和导电金球的框胶在粒径选型上难度较大，需要同时考虑两种粒子的作用和地形特点，实验条件搭配也会变得复杂。若导电金球选用过大，可能会导致间隔粒子压不下去，间隔粒子起不到压缩支撑作用，造成盒厚不良（Gap Mura）；而导电金球选用偏小，则可能会引起导通不佳。
