Abstract
A color display system that is capable of taking input intended to be displayed on a full color display (e.g. VDU) having a high refresh rate and displaying the image on a display having a much reduced number of displayable colors and a lower refresh rate. 24-bit RGB data is input and converted into bi-level RGBW data and halftoned in a render unit for storage before display. Motion detection is used to ensure that only those pixels that have change in value are updated on the display.
