James L Fergason: Optical display system and method with optical shifting of pixel position including conversion of pixel layout to form delta to stripe pattern by time base multiplexing. June 5, 2001: US06243055 (191 worldwide citation)

An optical display system and method selectively displaces delta triad pixels vertically. The first raster line of picture information is removed from the video signal, and each subsequent raster line of picture information (data) is displaced upward. Next, the entire picture is optically displaced ...
