ABSTRACT `DWz p5Ax
Based on analyzing the LC rear projective TV system, The OE (optical engine) for three penal LCoS rear projection TV Zh3]bg5
system has been designed and modeled, The OE (optical engine) of LC rear projection display is the main component of MzJ5_}
the system, and it directly affects final performance, so the design of good color performance, high brightness and CZwZ#WV6
contrast and high optical efficient is the key of the system. From a commercial viewpoint, a compact size and light %,6@Uu#%6
weight design makes it more competitive. LightTools software has a great many of powerful functions, such as M{O 2O(
modeling of optical system, analysis of illumination, modeling of machine structure, analysis of polarization and design ?;^_%XSQ*
of optical coating. We have used LightTools to analyses and optimize a whole optical engine of three penal LCoS QD\S E
projection display including illumination system, dividing and recombining of colors system, projection lens. At the end #-e3m/>
evaluated the performances of optical engine (parameters of output, uniformity, contract, resolution and so on). NbkWy
