ABSTRACT x}B3h9]
Based on analyzing the LC rear projective TV system, The OE (optical engine) for three penal LCoS rear projection TV NCL!|
system has been designed and modeled, The OE (optical engine) of LC rear projection display is the main component of gM>geWB<
the system, and it directly affects final performance, so the design of good color performance, high brightness and Y`3V&8X
contrast and high optical efficient is the key of the system. From a commercial viewpoint, a compact size and light wl7G6Y2
weight design makes it more competitive. LightTools software has a great many of powerful functions, such as LD/NMb
modeling of optical system, analysis of illumination, modeling of machine structure, analysis of polarization and design db#svj*
of optical coating. We have used LightTools to analyses and optimize a whole optical engine of three penal LCoS d;@"Naw
projection display including illumination system, dividing and recombining of colors system, projection lens. At the end fRh}n ^X
evaluated the performances of optical engine (parameters of output, uniformity, contract, resolution and so on). B63puX{u#
