目前,薄膜晶体管型液晶显示器(Thin-Film Technology Liquid Crystal Display, TFT-LCD)已成为显示领域的主流产品,而液晶面板是TFT-LCD的一个重要组成部分.LCD边缘漏光会导致画面失真,影响可视效果,造成画面显示品质下降、良率降低,因此改善边缘漏光成为急待解决的问题.本文研究了液晶与PI膜层取向异常对边角漏光的影响、LC Pattern设计对边角漏光的影响、Si-Ball型号对边角漏光的影响等,结果证明LC Pattern设计对边角漏光具有较好的改善效果,Pattern拉伸可改善边角漏光但更易造成液晶穿刺现象,小滴优化不仅能改善边角漏光而且也能防止液晶穿刺.另外小型Si-Ball对边角漏光改善效果最优,同时从信赖性验证等方面可以排除较小Si-Ball,限定出Si-Ball选择范围.
At present, Thin Film Transistor Liquid Crystal Display (TFT-LCD, Thin-Film Technology Liquid Crystal Display) has become the mainstream in the field of Display products, and LCD panel is an important component of TFT-LCD.LCD edge light-leaking can cause image distortion, affect the visual effects, resulting in lower quality display screen and yield, thus improving the edge light-leaking become an urgent problem to be solved.This paper studies the influence of the abnormal orientation of liquid crystal and PI film on the edge light-leaking, the influence of LC Pattern design on edge light-leaking, and the influence of the Si-Ball edge light-leaking.The result illustrates the LC Pattern design for edge light-leaking improvement has a good effect, the pattern drawing is more likely to cause LCD puncture phenomenon, the droplet optimization can be relatively better.The effect of small Si-Ball on the edge light-leaking is the best.Meanwhile, we eliminated the smaller silicon ball by reliability verification and found the range of Si-Ball.Excluding small Si-Ball limits the choice of Si-Ball from the reliability of validation and others.
