Abstract
Electrophoretic displays with multi-particle electrophoretic media and improved methods for driving such multi-particle electrophoretic media, especially using active matrix backplanes and controllers. The driving methods use faster gate updates with differential gaps between set of gate updates for a given pixel. The methods are generalizable to any electrophoretic display using push-pull waveforms, and are particularly well-suited for newer multi-particle electrophoretic displays capable of producing four or more colors at each pixel. Using such methods, electrophoretic displays will appear less 'flashy' than addressing with conventional row-by-row constant-frame-spacing updating.
