Abstract:
A direct view display comprising:a light source that generates input light comprising a plurality of spectral components; an output polarizer; an input polarizer disposed between said light source and said output polarizer; a first imaging stage, disposed between said input polarizer and said output polarizer, that receives the input light and outputs first stage light having the plurality of spectral components, said first imaging stage comprising: a first transmissive display, a first retarder stack, positioned at an input side of the first transmissive display, that preconditions a polarization of the input light such that the first transmissive display can selectively interact with a subset of the plurality of spectral components, and a second retarder stack positioned at an output side of the first transmissive display; a second imaging stage, disposed between said first imaging stage and said output polarizer, that receives the first stage light and outputs second stage light having the plurality of spectral components, said second imaging stage comprising: a second transmissive display, a third retarder stack, positioned at an input side of the second transmissive display, that preconditions a polarization of the first stage light such that the second transmissive display can selectively interact with a subset of the plurality of spectral components, and a fourth retarder stack positioned at an output side of the second transmissive display; and a third imaging stage, disposed between said second imaging stage and said output polarizer, that receives the second stage light and outputs third stage light having the plurality of spectral components, said third imaging stage comprising: a third transmissive display, a fifth retarder stack, positioned at an input side of the third transmissive display, that preconditions a polarization of the second stage light such that the third transmissive display can selectively interact with a subset of the plurality of spectral components, and a sixth retarder stack positioned at an output side of the third transmissive display.
