DISPLAY WITH TWO BINARY SPATIAL LIGHT MODULATORS

A display (10) has first and second spatial light modulators for modulating light from a light source. The first spatial light modulator (14) has a plurality of elements (16) switchable between ON and OFF states according to a pattern having a spatially-varying density. Transfer optics (26) blur and...

More Information
Summary:A display (10) has first and second spatial light modulators for modulating light from a light source. The first spatial light modulator (14) has a plurality of elements (16) switchable between ON and OFF states according to a pattern having a spatially-varying density. Transfer optics (26) blur and carry light modulated by the first spatial light modulator to the second spatial light modulator (20) to yield a light field at the second spatial light modulator. The second spatial light modulator has a plurality of elements (22) switchable between ON and OFF states to perform temporal dithering of the light field to provide a reconstruction of the image.
