Systems for three-dimensional viewing and projection

Abstract

Systems for three-dimensional viewing and projection aimed at full-color flat-screen binocular stereoscopic viewing without the use of eyeglasses for the viewer. According to the invention, light emanating from a display or projected thereat presenting a left image and a right image is directed only to the appropriate left or right eyes of at least one viewer using various combinations of light polarizing layers and layers of light rotating means or color filters.

What is claimed is:  
     
         1 . A system for three-dimensional viewing of a display, the display presents a frame divided into at least one first region presenting at least a part of a first image and at least one second region presenting at least a part of a second image, the system comprising a first and a second light polarizing layers each being divided into first subareas and second subareas, said second subareas being adjacent to said first subareas or being separated from said first subareas via opaque regions, said first subareas polarizing light in a first orientation, said second subareas polarizing light in a second orientation, said first layer being closest to the display, said second layer being between said first layer and a viewer, said first and second layers being in a distance from one another and said first and second subareas being distributed across and along said first and second layers such that light emanating from the at least one first region reaches one of the eyes of the viewer and is substantially blocked from the other eye, whereas light emanating from the at least one second region reaches the other eye of the viewer and is substantially blocked from the first eye.
