Abstract
A method of organizing and ordering pulse width modulation image data is disclosed, so that it may be displayed on the pixels of a scrolling color display. The method includes a method of formatting received image data into a different form suitable for driving a pulse width modulated display and a method of distributing image data across a series of different image modulation segments to minimize flicker and gray scale errors. The method includes means for reducing lateral field effects between adjacent pixels in different data states.
