ABSTRACT YR"IPyj
Based on analyzing the LC rear projective TV system, The OE (optical engine) for three penal LCoS rear projection TV W]5sqtF;6
system has been designed and modeled, The OE (optical engine) of LC rear projection display is the main component of mr+8[0
the system, and it directly affects final performance, so the design of good color performance, high brightness and )U+&XjK
contrast and high optical efficient is the key of the system. From a commercial viewpoint, a compact size and light 08z?i
weight design makes it more competitive. LightTools software has a great many of powerful functions, such as \ ccCrDz
modeling of optical system, analysis of illumination, modeling of machine structure, analysis of polarization and design \|7Y"WEQ
of optical coating. We have used LightTools to analyses and optimize a whole optical engine of three penal LCoS qf*e2" ~v
projection display including illumination system, dividing and recombining of colors system, projection lens. At the end \tfhF#'
evaluated the performances of optical engine (parameters of output, uniformity, contract, resolution and so on). |?LUt@r;
