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15μm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。
The performance of CF-LCoS was optimized by using the three-dimensional optical model of the CF-LCoS microdisplay device. By changing the pixel arrangement structure, the frictional structure of the liquid crystal alignment layer and the mode of the liquid crystal device, the lateral electric field effect is optimized to suppress the color light leakage phenomenon. The color purity of the CF-LCoS microdisplay, optimized for pixel size 15μm, can reach 63% of the NTSC color gamut range. The results show that the performance optimization of the CF-LCoS micro-display device based on the three-dimensional optical model can effectively suppress the color light leakage induced by the lateral electric field effect and greatly improve the color purity parameters of the device.
