Abstract
An autostereoscopic display of the invention includes: an illumination source for producing light of a first polarization and light of a second polarization different from the first polarization; a spatial light modulator for modulating the light of the first polarization and the light of the second polarization from the illumination source; and an optical system for directing the light of the first polarization to a first viewing region and the light of the second polarization to a second viewing region, wherein the spatial light modulator includes: a first polarization adjusting member for transmitting the light of the first polarization and substantially preventing transmission of the light of the second polarization; a second polarization adjusting member for transmitting the light of the second polarization and substantially preventing transmission of the light of the first polarization; and first and second groups of picture elements optically aligned with the first and second polarization adjusting member, respectively.
