Abstract
A high speed color display system including a modulation circuit electrically coupled between a high speed display device, such as an active matrix liquid crystal display panel, and a video output signal source, such as a video output card of a personal computer. The modulation circuit including both a scaling circuit for eliminating or substantially reducing contouring caused by quantizing errors associated with approximations of digital pictures and a duty cycle scaling circuit for eliminating or substantially reducing repetitive beats in a displayed image.
