Paper Abstract

In this letter, extending the normal OrCAD Pspice into electro-optical system of FLC, we construct an equivalent circuit model based on this principle; formulate the operation of the OASLM. Especially, we also show that the OASLM gray scale is realized not by FLC multidomain switching, but by uniform director rotation between bistable states. At the same time, the method could realize the dynamic switch simulation, memory characteristics and give the relation of memory threshold and critical pulse square, and show that this theory agrees with various experimental photographed trace results.
