Liquid Crystal on Silicon(LCOS) and Electro-Optic Characterization
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。
Abstract
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.
