摘要

偏光片作为液晶显示器的重要组成部分之一，其特性会直接影响到显示器的画面显示效果。文章首先对偏光片的基本组成进行了介绍，依据水分与偏光片透过率的关系，对偏光片相关的一种不良形成机理进行了分析，表明该不良的形成与湿度及偏光片的材质存在较大的相关性，通过使用不同材质偏光片的模组进行温湿度变化实验，验证了该不良的发生机理，同时针对该不良提出了改善方法，即在液晶显示器显示区域内避免偏光片局部与其他部品发生接触，或者在偏光片选取方面需选用位相差变化小的产品。

Abstract

The polarizer

one of the important parts of a liquid crystal display

impacts the quality of display directly. This paper introduced the basic composition of polarizer

and the formation mechanism of a defect related polarizer was analyzed according to the relationship of moisture and transmittance of polarizer. It showed the formation of the defect is related to the humidity and polarizer material. Then it conducted a test with different modules whose polarizers were made of different materials

in variation temperature and humidity. The results verified the formation mechanism

at the same time established the solution for this defect

that was in active area of display

local polarizer should avoid to contact with other components

or to choose the polarizer that has small change in phase difference.
