文章概述了硅基液晶（LCOS）所使用的反射式显示模式的关态特性，研究基础是均匀扭曲液晶盒的Jones矩阵，同时介绍了郭海成提出的参数空间方法和基于光学等价定理的“理想”模式，并强调了显示模式本身引起的光学色散，而光的利用率要求备选模式落在参数空间曲线的极值点附近。

We outline off-state characterization of reflective display model, which is mainly used in liquid crystal on silicon(LCOS). Study is based on the Jones matrix for liquid crystal cell with uniform twist. The parameter space method proposed by Kwork H. S., and "ideal" model based on the optical equivalence theorem, is introduced. The color dispersion caused by model-self is emphasized and a favorable model should be around an extreme value point on the contour map of the parameter space in order to condition the optical efficiency.
