LIU Jie, LI Dong-xi, JIN Jiong-tai, WANG Zhang-tao, SHAO Xi-bin. Defect Related to Polarizer in TFT-LCD[J]. , 2013,28(6): 872-876 DOI: 10.3788/YJYXS20132806.0872.
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.
