摘要

从HADS产品像素漏光现象出发，分析了HADS产品产生像素漏光的主要原因和机理。通过分析发现，HADS产品像素漏光主要是因为摩擦弱区液晶配向角度异常导致的透过率差异产生的。并在此基础提供摩擦方向优化和PS形状优化以减少摩擦弱区对像素漏光的影响。为更好画面品质的HADS产品提供了改善方向。

Abstract

Based on the pixel leakage phenomenon of advanced super dimension switch (HADS) products

the main causes and mechanisms of pixel leakage caused by HADS products were analyzed. Through the analysis

it is found that the light leakage of the HADS product is mainly caused by the difference in transmittance caused by the abnormal alignment angle of the rubbing weak region liquid crystal. Based on this

the two directions of improvement of Rubbing direction optimization and PS shape optimization are provided for the better picture quality of HADS products.
