ABSTRACT .v;$sst5y
Based on analyzing the LC rear projective TV system, The OE (optical engine) for three penal LCoS rear projection TV $/^DY&
system has been designed and modeled, The OE (optical engine) of LC rear projection display is the main component of ^]:w5\DG
the system, and it directly affects final performance, so the design of good color performance, high brightness and 4TcKs}z
contrast and high optical efficient is the key of the system. From a commercial viewpoint, a compact size and light ZYDLl8
weight design makes it more competitive. LightTools software has a great many of powerful functions, such as nI4Kuz`dF
modeling of optical system, analysis of illumination, modeling of machine structure, analysis of polarization and design @b[{.m U
of optical coating. We have used LightTools to analyses and optimize a whole optical engine of three penal LCoS 1%~yb Q
projection display including illumination system, dividing and recombining of colors system, projection lens. At the end ) * Mr{`
evaluated the performances of optical engine (parameters of output, uniformity, contract, resolution and so on). h{xC0NC)
Keywords: optical engine, illumination system, projection display, LCoS
