Abstract
This application is directed to driving methods for electrophoretic displays. The driving methods comprise grey level waveforms which greatly enhance the pictorial quality of images displayed. The driving method comprises: (a) applying waveform to drive each pixel from its initial color state to the full first color then to a color state of a desired level; or (b) applying waveform to drive each pixel from its initial color state to the full second color then to a color state of a desired level.
