引言近十年来,锆钛酸铅镧(PLZT)电光器件一直用来作光的快门,直到最近几年才用作显示器件.PLZT显示器具有:在宽的工作温度范围内响应速度快,适用于强光下显示,视角宽,全固体结构以及功耗极低等优点.PLZT技术的进一步发展是用于信息容量大的点阵显示,本文主要介绍这方面的工作. Introduction In the last decade, PLZT electro-optical devices have been used as light shutters and have not been used as display devices until recent years. The PLZT display has: fast response over a wide operating temperature range, Strong light display, wide viewing angle, all-solid structure and low power consumption, etc. The further development of PLZT technology is used for the dot matrix display with large information capacity. This article mainly introduces the work in this field.
