Abstract:
Methods and systems are described herein which produce polarization-independent full color images suitable for rear-projection television sets and other multimedia displays. The system uses illumination with R, G, B light from two different light sources for each color. A viewer wears glasses with narrowband optical filters, preferably holographic filters. The R, G, B light from the light sources is slightly offset at each of the 3 emission wavelengths, with one set of R, G, B light being filtered by the holographic filter in front of the left eye of the, and the other set of R, G, B light being filtered by the holographic filter in front of the viewer's right eye.
