ABSTRACT I[vME"
Based on analyzing the LC rear projective TV system, The OE (optical engine) for three penal LCoS rear projection TV ~9]Vy
(L
system has been designed and modeled, The OE (optical engine) of LC rear projection display is the main component of 8~rT
the system, and it directly affects final performance, so the design of good color performance, high brightness and <: H
contrast and high optical efficient is the key of the system. From a commercial viewpoint, a compact size and light 0!)U *+j,
weight design makes it more competitive. LightTools software has a great many of powerful functions, such as qrOB_Nz
modeling of optical system, analysis of illumination, modeling of machine structure, analysis of polarization and design 4_Tb)?L +:
of optical coating. We have used LightTools to analyses and optimize a whole optical engine of three penal LCoS %Gnd"SGs
projection display including illumination system, dividing and recombining of colors system, projection lens. At the end UX+?0 K
evaluated the performances of optical engine (parameters of output, uniformity, contract, resolution and so on). .kz(V5
