摘　　要：文章以向列相液晶的弹性理论和Jones矩阵方法为研究基础,给出了90°MTN模式的电压-反射率实验曲线,概述了硅基液晶(LCOS)所使用的反射式显示模式的电压开态特性。对红、绿、蓝三色光,给出了90°MTN和SCTN两种模式的电压-反射率特性曲线,强调了电压开态下的色散效应。对于5V的暗态工作电压,给出了TN-ECB-1和45°MTN两种模式对比度随盒厚的变化曲线。The voltage-reflectance curve is given experimentally for our 90°MTN model. We outline voltage-on-state characterization of reflective display model,which is mainly used in liquid crystal on silicon（LCOS） . Study is based on the elastic theory of nematic liquid crystal and the method of Jones matrix. For the red,green and blue lights,we show the voltage-dependent reflectance of a 90° MTN model and a SCTN model. The color dispersion effect is emphasized in the voltage-on-state. The contrast ratio as a function cell gap is given for the TN-ECB-1 model and 45°MTN model,in which the voltage for dark state is 5V.
