Classification: CPC H  G | IPC G  H

Claim 11:
12. Apparatus for displaying video data, the video data specifying video frames for display at a frame rate, the apparatus comprising:
a light source operative to emit light;
a two-dimensional spatial phase modulator that receives the light from the light source and is operable to phase modulate the light and direct resulting phase-modulated light to a viewing area; and
a data processor configured to:
in real time, process the video data to yield a sequence of phase-modulator control signals at the frame rate; and
apply the phase modulator control signals to the two-dimensional spatial phase modulator to cause the phase modulator to phase modulate the light to redistribute light from one or more first regions of the video frames to one or more second regions of the video frames to project the video data in high dynamic range (HDR), the one or more second regions brighter than the one or more first regions.
