Patent ID: 7347559

Claim:
An apparatus comprising: a transflective polarizing beam splitter capable of receiving first, second, and third wavelength bands of light, the transflective polarizing beam splitter being further capable of transmitting the first wavelength band of light, in a first polarization direction, and capable of reflecting the second and third wavelength bands of light, in a second polarization direction; first, second and third reflective liquid crystal light valves capable of reflecting at least a portion of the first wavelength band of light in the second polarization direction, at least a portion of the second wavelength band of light in the first polarization direction, and at least a portion of the third wavelength band of light in the first polarization direction, respectively, generally toward a projection lens; and a spectrally selective output device capable of receiving at least the portion of the first wavelength band of light and changing the portion of the first wavelength of band of light from the second polarization direction to the first polarization direction.
