Abstract

The photoaddressed liquid crystal light valves which are widely used in optical information process and large screen display^1,2, are mainly composed of optical and opto-electrical films (shown in Fig.1). In order to improve the performance of the LCLV, all these films should be refined and made perfectly, especially the photoconductive films which determine the opto-electronic characteristic. With the high quality of CdS/CdSe photoconductive film and all other optical and opto-electrical films, the LCLV gets good contrast ratio(>100:1 white light), fast response (<15ms), high brightness (>20001m) and high resolution (>50pl/mm).
