氨气对偏振片作用的试验验证

液晶显示器的显示性能,如对比度、亮度等,与所用偏振片的性能有很大关系。随着使用时间的延续,偏振片会老化,其性能也相应下降。如果在不恰当的条件下使用或仓储,偏振片会加速老化,性能会加速下降,甚至完全失效。氨气是一种碱性气体,可能会与偏振片中的有机高分子成分发生化学反应,导致偏振片快速老化。本文侧重通过试验验证氨气对偏振片的影响,对比常见两大系列偏振片受影响的程度,并为行业内偏振片和LCD成品的存储与使用环境提出要求。

A Verification by Experiments about Ammonia' influences to Polarizers

The electrooptical functions of the liquid crystal display, such as contrast,luminance etc., are greatly correlative with used polarizers. The polarizers will gradually age along with usage. Their optical functions will descend gradually. If the polarizers are used or stored in a infelicitous environment袁they will accelerativly age, and their optical functions will accelerativly descend,even to be disabled entirely. The ammonia is a kind of alkaline gas, it may make chemical responses with organic compounds in the polarizers, result in the polarizers' fast disability. This article lays emphasis on the verification by experiments about ammonia' influences to the polarizers ,and compares the suffering influences of two familiar styles of Iodine polarizer and Dyestuff polarizer. It will put forward a request for the environment in which polarizers are used or stored .
