Patent ID: 7375772

Claim:
A system, comprising: a light source capable of producing light in first, second and third wavelength bands in a second polarization direction; a transflective polarizing beam splitter comprising one of a wire grid device, a multi-layer thin film device, a cholesteric polymer liquid crystal device, a laminated polymer sheet device, or combinations thereof, the transflective polarizing beam splitter being capable of receiving the 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; and first, second and third reflective liquid crystal light valves capable of reflecting at least a portion of the respective first, second and third wavelength bands of light generally toward a projection lens.
