Title: Increasing the number of colors output by an active liquid crystal display

Abstract: A technique increases the number of colors output by an active color display by providing an increased number of grey levels for each pixel component. An M.times.N matrix pattern of pixel components is generated having a ratio of pixel components at a particular color level to pixel components at a different color level to achieve a particular grey level, where M and N are greater or equal to two. The M.times.N matrix pattern is repeated for X frames, and at least one pixel component is at the particular color level in each frame. At the end of the Nth frame, the matrix pattern from frame zero is repeated.
