ABSTRACT 8xg:ItJaA0
Based on analyzing the LC rear projective TV system, The OE (optical engine) for three penal LCoS rear projection TV 3 {on$\
system has been designed and modeled, The OE (optical engine) of LC rear projection display is the main component of ?)4|W N|c_
the system, and it directly affects final performance, so the design of good color performance, high brightness and 1x M&"p:
contrast and high optical efficient is the key of the system. From a commercial viewpoint, a compact size and light qdZn9 i
weight design makes it more competitive. LightTools software has a great many of powerful functions, such as #5 G!lbH
modeling of optical system, analysis of illumination, modeling of machine structure, analysis of polarization and design X"iy .@7
of optical coating. We have used LightTools to analyses and optimize a whole optical engine of three penal LCoS jc Ie<i;
projection display including illumination system, dividing and recombining of colors system, projection lens. At the end N< Y-]xS
evaluated the performances of optical engine (parameters of output, uniformity, contract, resolution and so on). ,!%[CpM3
Keywords: optical engine, illumination system, projection display, LCoS
