Abstract: A holographic universal display according to the present invention uses reflective lighting for a liquid-crystal panel. The system comprises at least two waveguide holograms in a matched configuration that redirects incident light beams as diffracted beams so that the beams passing out of the display are targeted towards the viewer. That is to say, light beams that are incident to the display at large angles, over a wide range, with respect to normal are redirected into a set, narrow range of angles close to the required angle for optimal viewing. The required angle for optimal viewing is nominally perpendicular to the plane of the display (i.e., normal), but is optionally selectable (by design of the holograms) to be an angle varies from the strict perpendicular.

Abstract: The method and system of the present invention displays autostereographic images without parallax barriers or loss of resolution. A stereopair is processed and sent to a distant display and one or more transmissive displays placed in front of it. Each display has a calculated images containing at least some of the image information destined for both eyes of a viewer. Each display acts as a mask for the other displays. The processing of the stereopairs to produce calculated images comprises summing the predicted image data, comparing the predicted image data to the desired stereopair, and minimizing the error. In a preferred embodiment, this processing is performed by an artificial neural network. A spatial mask, such as a diffuser, can be placed between displays to suppress Moir{acute over (e )} patterns.
