<p>Described is a display system including an illumination system which utilizes a light collector in the form of a non-imaging reflector (26, 32, 38) having a rectangular output aperture, a modulating device (28, 34, 40) in the path of light emitted by the illumination system, and a projection lens (44). Three such collectors (26, 32, 38) having spectrally tuned lamps (24, 30, 36) therein and using rectangular LCD's (28, 34, 40) as modulating devices can be used in a television projection system.</p> |
