ABSTRACT _D+J3d(Pjk
Based on analyzing the LC rear projective TV system, The OE (optical engine) for three penal LCoS rear projection TV m^RO*n.
system has been designed and modeled, The OE (optical engine) of LC rear projection display is the main component of ?%Q=l;W.
the system, and it directly affects final performance, so the design of good color performance, high brightness and .k
up[d(
contrast and high optical efficient is the key of the system. From a commercial viewpoint, a compact size and light v$;URF%^
weight design makes it more competitive. LightTools software has a great many of powerful functions, such as Sy*p6DP
modeling of optical system, analysis of illumination, modeling of machine structure, analysis of polarization and design oj?y_0}:^
of optical coating. We have used LightTools to analyses and optimize a whole optical engine of three penal LCoS 3F6A.Ny
projection display including illumination system, dividing and recombining of colors system, projection lens. At the end B'y)bY'_dS
evaluated the performances of optical engine (parameters of output, uniformity, contract, resolution and so on). K1;b4Sl?A
Keywords: optical engine, illumination system, projection display, LCoS
