Description

背光模组及窄边框液晶显示模组 技术领域
本发明涉及显示技术领域，尤其涉及一种背光模组及窄边框液晶显示模组。
 背景技术
薄膜晶体管（Thin Film Transistor，TFT）是目前液晶显示装置（Liquid Crystal Display，LCD）和有源矩阵驱动式有机电致发光显示装置（Active Matrix Organic Light-Emitting Diode，AMOLED）中的主要驱动元件，直接关系平板显示装置的显示性能。
现有市场上的液晶显示器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薄膜晶体管阵列基板（Thin Film Transistor Array Substrate，TFT Array Substrate）与彩色滤光片（Color Filter，CF）基板之间灌入液晶分子，并在两片基板上分别施加像素电压和公共电压，通过像素电压和公共电压之间形成的电场控制液晶分子的旋转方向，以将背光模组的光线透射出来产生画面。
现有的背光模组上，会在胶框上贴黑白双面或黑黑双面的口字胶，以此来达到连接液晶显示面板与背光模组以及防止膜片跳脱的作用，同时口字胶还用于遮掩背光模组内导光板及光学膜片与胶框的间隙，起到防漏光的作用。 口字胶要能防止膜片跳脱，其环状结构的内环一定要延伸到光学膜片上，并且对延伸到光学膜片上的宽度有一定的要求，同时，口字胶要贴合在胶框上，需要一定的稳定性，因此胶框也需要一定的宽度来保证贴合的强度，背光模组的胶框的宽度大于液晶面板的宽度，从而对胶框宽度的最小值也提出了要求。 
现有的口字胶位于胶框两侧边宽度的量产极限值为0.45mm，随着现有的液晶显示模组的边框越来越窄，致使口字胶位于胶框两侧边宽度已小于0.45mm的量产极限值，例如液晶显示模组的边框为0.6mm时口字胶位于胶框两侧边宽度为0.3mm，致使目前窄边框液晶显示模组中口字胶的加工及组装有很大的困难。
