Abstract
In display systems employing spatial light modulators, the OFF-state light from OFF-state pixels of the spatial light modulator can be captured and directed back to the pixels of the spatial light modulator so as to recycle the OFF-state light in the display system. Bitplanes derived from the desired image to be produced are calibrated to include the recycled off-state light to properly produce the desired image using the display system.
