摘要
本文介绍一种改进的激光选址液晶光阀。它以液晶的光散射态(暗态)为显示背景,减少了对观察者眼睛的刺激;它的整体擦除时间大约0.5~1s.采用以暗态为背景的方案,必须对光阀施加高电压才能进行整体擦除,高电压容易使光阀击穿。本文采用在导电层与吸收层之间镀隔离层,就可避免因加大液晶层厚度使写入光灵敏度降低,又增加了高电压与大电流的承受能力。
In this paper, an improved laser-addressed LCLV is reported.It em-ploys scattering structure of smectic liquid crystal as display background. ItsLC layer will not be easily electrically broken down. Full erasure can be ach-ieved within.0.5~1 second.We also present a new method utilizing an insulativelayer (inert insulative film) that is sandwiched between ITO and absorbtivelayer. Such structure makes it possible to avoid decreasing LCLV′s input sen-sitivity which is caused by increase of LC layer thickness, to improve bearingability to high voltage and large current, and achieve fast full erasure.Itshighest breakdown voltagte reaches 690 Vrms.
