Abstract:
A sequential color display system comprising:a white light source for emitting a beam of light along a first light path; a first set of dichroic filters on said first light path, said first set of dichroic filters operable to separate said beam of light into three primary color light beams traveling along three primary color light paths; three spatial light modulators, each of said three spatial light modulators on one of said three primary color light paths, each of said three spatial light modulators operable to selectively transmit portions of said primary color light beams; a second set of dichroic filters positioned to combine said selectively reflected portions of said primary color light beam into a recombined light beam; and a projection spatial light modulator positioned to receive said recombined light beam and to selectively transmit portions of said recombined light beam to an image plane in response to image data signals received from a controller.
