Paper Abstract

A compact 60-inch LCD rear projection television optimized with depth less than 60 cm has been developed by using three 1.3' poly-Si TFT-LCDs of 1024 X 768 pixels resolution. Three primary colors of the projection system are separated and synthesized by dichroic mirrors and X-prism respectively. Polarization converter is used to increase the optical throughput and an aspherical hybrid projection lens with f equals 19.97 mm and f/# equals 2.4 is designed to effectively shorten the projection distance. A Fresnel lens and a fine lenticular lens screen can create a morie' pattern free picture. Under a 120 W UHP lamp, the brightness of the rear projection TV can achieve 460 nits luminance.
