Patent ID: 7057580

Claim:
An image display system for forming an image on a single image display surface by image blocks comprising: (a) at least one complementary screen of one of light emitting or light source modulating devices producing light in a two dimensional array of N (a real number) pixels, from which array of pixels a plurality of raster elements are generated; (b) a raster multiplying system for parallel scanning image blocks of a single image display surface comprising an array of optically interrelated light dividing elements, each said light dividing element to divide the light of said plurality of raster elements of the complementary screen into parts, a first section of said array arranged to directly receive light from said complementary screen, a part of which directly received light is passed to at least one other section of said array, the light directly received by said first section of said array and the light passed to said at least one other section of said array divided into components to form copies of the raster elements, with said copies of said raster elements forming corresponding raster elements in P image blocks, each block of said P image blocks generally comprising a two dimensional array of said raster element copies; (c) an array of controllable modulators located after said raster multiplying system, each modulator of said array to independently modulate the raster elements of one of said P image blocks so that light in each block is modulated separately and simultaneously; and (d) a single image display surface on which said P image blocks of a total number of M pixels are formed and displayed, where the number M exceeds the number N and where said surface preceding components of (a), (b) and (c) are placed in the mentioned order of the light path of the complementary screen.
