Patent ID: 7072003

Claim:
An apparatus comprising: a light source to produce light in first, second and third wavelength bands in a second polarization direction; a spectrally selective input device to receive the first, second, and third wavelength bands of light from the light source; to transmit the first wavelength band of light in a first polarization direction; and to transmit the second and third wavelength bands of light in the second polarization direction; a plate-type transflective polarizing beam splitter to recieve the first, second and third wavelength bands of light, to transmit, in a first polarization direction, the first wavelength band of light, and to reflect, in a second polarization direction, the second and third wavelength bands of light; a color filter to recieve the second and third wavelength bands of light, to transmit in second polarization direction, the second wavelength band of light, and to reflect in the second polarization direction, the third wavelength band of light; and first, second and third reflective liquid crystal light valves to selectively reflect portions of the respective first, second and third wavelength bands of light toward a projection lens.
