ABSTRACT R{H[ < s+n
Based on analyzing the LC rear projective TV system, The OE (optical engine) for three penal LCoS rear projection TV VIT|#
system has been designed and modeled, The OE (optical engine) of LC rear projection display is the main component of _VK I@
the system, and it directly affects final performance, so the design of good color performance, high brightness and sF{aG6u
contrast and high optical efficient is the key of the system. From a commercial viewpoint, a compact size and light / D&&7;jJ
weight design makes it more competitive. LightTools software has a great many of powerful functions, such as p UXoSnIq:
modeling of optical system, analysis of illumination, modeling of machine structure, analysis of polarization and design eluN~T:W
of optical coating. We have used LightTools to analyses and optimize a whole optical engine of three penal LCoS !#c'|
*k
projection display including illumination system, dividing and recombining of colors system, projection lens. At the end `5IrV&a
evaluated the performances of optical engine (parameters of output, uniformity, contract, resolution and so on). eT haH0
Keywords: optical engine, illumination system, projection display, LCoS
