ABSTRACT:
A multicolor display system includes a graphics display controller for selectively generating bit patterns of pixel data for a plurality of images for display; a plurality of memories for storing the bit patterns for each image respectively, and for establishing a plurality of individual memory planes each associated with particular ones of the images; a color look-up table coupled to the memories for receiving the bit patterns therefrom and selectively establishing a color priority hierarchy among the associated image planes, for providing for display only the pixel data bits associated with the highest priority image plane at display locations or pixel points where the images of two or more image planes intersect; and D/A converters for converting the pixel data bits for each memory plane from the look-up table to analog signals for connection to a display device.
