ABSTRACT:
A display device which is capable of producing a plurality of different views of an image simultaneously is provided. The display includes an array of semiconductor devices with an electro-optical material disposed over the array of semiconductor devices. The semiconductor devices include electrodes which are selectively activated to form refraction gratings in the electro-optical material. Each of the semiconductor devices also includes a processor layer which can determine a refraction grating which is necessary for generating a predetermined number of discrete images which are visible from a predetermined number of different vantage points or viewer positions. Since a different image is provided to each eye, the viewer is provided with a perception of depth such that a three-dimensional image is provided. In addition, since different images or at least different image perspectives are provided to different points, horizontal and/or vertical parallax of the display is attained.
