International Classification:

G09G005/02

US Classification:

345589000

Abstract:

A method of operating a pixel includes generating one of m possible data streams from an n-bit input that represents a desired intensity level. The data stream is usable to drive a pixel to the desired intensity level. Each of the m data streams includes a plurality of frames. The method further includes pseudo-randomly selecting a starting frame from the plurality of frames in the data stream for a specific pixel, using the selected data stream to drive the specific pixel, and pseudo-randomly selecting a different starting frame for a different specific pixel.
