ABSTRACT N2BI_,hI1
Based on analyzing the LC rear projective TV system, The OE (optical engine) for three penal LCoS rear projection TV k;k}qq`d
system has been designed and modeled, The OE (optical engine) of LC rear projection display is the main component of Zb(E:~h\
the system, and it directly affects final performance, so the design of good color performance, high brightness and FZ F @
contrast and high optical efficient is the key of the system. From a commercial viewpoint, a compact size and light W^es;5
weight design makes it more competitive. LightTools software has a great many of powerful functions, such as <:&de8bT
modeling of optical system, analysis of illumination, modeling of machine structure, analysis of polarization and design )P?IqSEA%
of optical coating. We have used LightTools to analyses and optimize a whole optical engine of three penal LCoS ?c]n^GvG
projection display including illumination system, dividing and recombining of colors system, projection lens. At the end 5,1{Tv`
evaluated the performances of optical engine (parameters of output, uniformity, contract, resolution and so on). yhpz5[AuO
