ABSTRACT
w%3Fg~Up
Based on analyzing the LC rear projective TV system, The OE (optical engine) for three penal LCoS rear projection TV )W 8L91-
system has been designed and modeled, The OE (optical engine) of LC rear projection display is the main component of /M^V 2=
the system, and it directly affects final performance, so the design of good color performance, high brightness and ,!6M* |
contrast and high optical efficient is the key of the system. From a commercial viewpoint, a compact size and light _%wK}eH+sy
weight design makes it more competitive. LightTools software has a great many of powerful functions, such as .!JMPf"QEI
modeling of optical system, analysis of illumination, modeling of machine structure, analysis of polarization and design -`!_ h[
of optical coating. We have used LightTools to analyses and optimize a whole optical engine of three penal LCoS cBifZv*l
projection display including illumination system, dividing and recombining of colors system, projection lens. At the end ~reQV6oQua
evaluated the performances of optical engine (parameters of output, uniformity, contract, resolution and so on). :tMre^o P
