Abstract:
A display has first and second spatial light modulators for modulating light from a light source. The first spatial light modulator has a plurality of elements switchable between ON and OFF states according to a pattern having a spatially-varying density. Transfer optics blur and carry light modulated by the first spatial light modulator to the second spatial light modulator to yield a light field at the second spatial light modulator. The second spatial light modulator has a plurality of elements switchable between ON and OFF states to perform temporal dithering of the light field to provide a reconstruction of the image.
