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×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×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.
