Abstract
This application is directed to driving methods for electrophoretic displays. The driving methods comprise applying different voltages selected from multiple voltage levels, to pixel electrodes and optionally also to the common electrodes. In one embodiment, the different voltages are selected from a group consisting of 0V, at least two levels of positive voltage and at least two levels of negative voltage. The driving method is also suitable for a color display device.
