Patent ID: 7358930

Claim:
A display system for displaying an image, comprising: an image processing unit configured to process image data and generate a number of image sub-frames corresponding to said image data; a modulator configured to modulate a light beam according to said image sub-frames; a scrolling color device configured to scroll a plurality of colors across a face of said modulator, wherein all of said plurality of colors are present simultaneously on said face of said modulator, to produce a color light beam bearing said number of image sub-frames; display optics configured to display said image from said color light beam; and a wobbling device configured to displace said color light beam according to a cycle in which said image sub-frames are sequentially displayed in a cycle of spatially offset positions, said spatially offset positions being offset by less than a pixel width from each other; wherein said scrolling color device scrolls said plurality of colors across said face of said modulator an integer number of times during an image sub-frame time period corresponding to said each of said number of image sub-frames; and further comprising a system timing unit configured to synchronize said scrolling color device and said wobbling device such that said scrolling color device scrolls said plurality of colors across said face of said modulator an integer number of times during an image sub-frame time period corresponding to each of said number of image sub-frames.
