Abstract

A process for producing a wide range of colors in images that are presented in successive frames on image fields (13) on color opto-electronic display means having separate illumination elements each of a different color at each pixel location. Each pixel location, for example, may have a red, a green and a blue illumination element. The display is divided into uniformly-sized display neighborhoods (17). The process includes, for a given pixel location (a-p) within any one of the uniformly-sized display neighborhoods, producing a given color at that pixel location by selecting a frame sequence for illuminating the illumination elements at the pixel location during presentation of an image wherein the number of times that any given illumination element at the pixel location is illuminated within a given frame sequence is controlled to create an appearance of color shading of that pixel location relative to other pixel locations and wherein adjacent pixel locations that have the same color within any one of the display neighborhoods have their illumination elements illuminated with different frame sequences to minimize display noise.
