ABSTRACT:
A high resolution, multicolor frame buffer memory and sequential read/write logic provides high speed access and reduced memory requirement for a scanning display. Frame buffer memory bits are assigned corresponding display location color values according to a selected pattern and color distribution scheme. Current display locations and neighboring display locations, including subsequent and/or preceding display lines, are examined to assemble color information for each current display location, such that a plurality of color values are combined for each display location, even though the frame buffer memory only stores one color value for each display location.
