Abstract

A system and method for monitoring the status of a pixelated display defines one or more pixel locations or clusters of pixels to be dithered. A monitor determines if the specified pixels or clusters of pixels demonstrate dithering. Detection of the expected dithering indicates a functional display while failure to detect the dithering indicates a failed display. Brightness levels are monitored to detect a failure in brightness leveling. Brightness is monitored at the same locations.
