Abstract:
An electro-optical image display system for producing visible images for viewing by a viewer, comprising:electromagnetic beam producing means for producing an electromagnetic beam having substantially collimated beam characteristics; control signal producing means for producing electrical control signals in response to video signals representative of an image to be displayed; and an image display device having a display surface having substantially planar surface characteristics, and an array of beam steering elements arranged in the form of a logic tree structure, each said beam steering element comprising a passive CLC element and an electrically-active CLC element, and being controllable for steering said electromagnetic beam within said image display device, wherein, in response to said electrical control signals produced by said control signal producing means, one or more of said beam steering elements steers said electromagnetic beam along a, so that light rays in the visible spectrum emerge from said display surface to thereby produce said image on said display surface, for viewing by said viewer.
