Patent ID: 7077524

Claim:
A color projection display device for displaying a temporally-integrated more-than-three-primary-color image comprising first and second sequences of temporally-integrateable primary color image components, the device comprising: first and second spatial light modulator panels including first and second arrays of pixel elements, respectively; an illumination configuration to produce a sequence of a plurality of color filtered light beams having a plurality of filtered wavelength spectrums, respectively; and a beam divider/combiner able to: produce a plurality of sub-spectrum light beams of at least four different primary colors by separating each color filtered light beam in said sequence of color filtered light beams into a first sub-spectrum beam whose color corresponds to the color of one of the primary color image components in said first sequence of temporally-integrateable components, and a second sub-spectrum beam whose color corresponds to the color of one of the primary color image components in said second sequence of temporally-integrateable components; direct the first sub-spectrum beam resulting from each of said plurality of color filtered light beams onto said first spatial light modulator panel, and direct the second sub-spectrum beam resulting from each of said plurality of color filtered light beams onto said second spatial light modulator panel; receive a first sequence of patterned colored light beams reflected from said first spatial light modulator panel, each patterned colored light beam in said first sequence of patterned colored light beams carrying one primary color image component of said first sequence of temporally-integrateable primary color image components; receive a second sequence of patterned colored light beams reflected from said second spatial light modulator panel, each patterned colored light beam in said second sequence of patterned colored light beams carrying one primary color image component in said second sequence of temporally-integrateable primary color image components; and produce a combined output beam carrying both said first and said second sequences of temporally-integrateable primary color image components, by directing both said first and second sequences of patterned colored light beams in an output direction.
