Abstract

LC(liquid crystal) rear projection display possesses a lot of advantages, such as high brightness, compact size, good color performance, which make it a very attractive market trend. The OE (optical engine) of LC rear projection display is the main component of the system, and it directly affects final performance, so the design of good color performance, high brightness and contrast and high optical efficient is the key of the system. From a commercial viewpoint, a compact size and light weight design makes it more competitive. LightTools software has a great many of powerful functions, such as modeling of optical system, analysis of illumination, modeling of machine structure, analysis of polarization and design of optical coating. We have used LightTools to analyses and optimize an optical engine of three penal LCoS projection display and evaluated the optical engine( parameters of output, uniformity, contract, resolution and so on).
