摘要
应用彩色滤光膜硅覆液晶（CF-LCoS）微显示器件的三维光学模型对CF-LCoS的性能进行优化。通过改变像素排列结构、液晶取向层的摩擦结构以及液晶器件模式等条件优化侧向电场效应，抑制彩色漏光现象。通过优化，像素尺寸为15 μm的CF-LCoS微显示器件，其色纯度可以达到美国国家电舰系统委员会(NTSC)色域范围的63%。结果表明，基于三维光学模型的CF-LCoS微显示器件的性能优化可以有效抑制侧向电场效应诱导产生的彩色漏光现象，大幅提升器件的色纯度参数。
Abstract
With the three-dimensional (3D) optical analysis as a tool, the optimization of the fringing field effect in the color filter liquid-crystal-on-silicon (CF-LCoS) microdisplays is obtained by changing pixel arrangement, rubbing direction, and liquid crystal (LC) mode. The color purity of the CF-LCoS microdisplays could attain 63% national television system committee (NTSC) level for a typical pixel size of 15 μm. With the optimization, the color fringing effect of CF-LCoS is minimized and the color purity of the device is increased.
