ABSTRACT:
A method of controlling the brightness levels on a screen includes determining a total number of screen pixels that must be energized to realize various brightness levels throughout the display. The display preferably is generated in a sequence of frames that are subdivided into energization states. An electronic controller determines an order of energizing selected ones of the pixels during each of the energization states to realize the desired brightness levels for the display while reducing drive load variation and realizing more efficient power consumption.
