  • Patent number: 10303030
    Abstract: A privacy display comprises a polarized output spatial light modulator, reflective polarizer, switchable liquid crystal retarder and polarizer. In a privacy mode of operation, on-axis light from the spatial light modulator is directed without loss, whereas off-axis light has reduced luminance. Further, display reflectivity is reduced for on-axis reflections of ambient light, while reflectivity is increased for off-axis light. The visibility of the display to off-axis snoopers is reduced by means of luminance reduction and increased frontal reflectivity to ambient light. In a wide angle mode of operation, the liquid crystal retardance is adjusted so that off-axis luminance and reflectivity are unmodified.
