Spatio-temporal directional light modulator

摘要

A spatio-temporal directional light modulator is introduced. This directional light modulator can be used to create 3D displays, ultra-high resolution 2D displays or 2D/3D switchable displays with extended viewing angle. The spatio-temporal aspects of this novel light modulator allow it to modulate the intensity, color and direction of the light it emits within an wide viewing angle. The inherently fast modulation and wide angular coverage capabilities of this directional light modulator increase the achievable viewing angle, and directional resolution making the 3D images created by the display be more realistic or alternatively the 2D images created by the display having ultra high resolution.

1. A directional light modulator comprising:
a two dimensional emissive micro emitter array device having an array of individually addressable emissive pixels; a micro lens array of micro lens elements; the two dimensional emissive micro emitter array device and the micro lens array being assembled together and angularly articulated as a single assembly in an angular motion having a periodicity selected to enable temporal coverage of the maximum articulation angle within an image frame duration to emit light around two axes within a plane of an emissive surface of the emissive micro emitter array and within a range of plus and minus a maximum angular articulation in each respective axis.
