彩色滤光膜硅覆液晶微显示器中像素尺寸及滤光膜厚度对彩色侧向场效应的影响

应用彩色滤光膜硅覆液晶(Color Filter Liquid Crystal on Silicon，CF-LCoS)微显示器件的三维光学模型; 研究了像素尺寸和彩色滤光膜厚度对彩色侧向场的影响。这两个参数可以影响微显示器件的色纯度、光反射率以及对比度等性能参数。对于特定的应用，需要考虑器件所有的性能参数要求，才能对像素尺寸和彩色滤光膜厚度进行优化。The relation of color fringing field with the pixel size and thickness of color filters was researched in this paper, and the study was based on the three-dimensional (3D) optical modeling we established before. These two parameters may affect the color, reflectivity, contrast, and other properties of the CF-LCoS microdisplays. The optimization of pixel size and thickness of color filters should be compromised among these display properties for specific applications.
