ABSTRACT:
A method for driving an active matrix electrophoretic display is provided. In a resetting period Tr, reset data Drest is supplied to a data line drive circuit and a reset voltage is applied to each pixel electrode. Next in a writing period, an image data is supplied to a data line drive circuit and a gradation voltage is applied to each pixel electrode. Subsequently a common voltage is applied to it, in order to take charge which is accumulated between the electrodes away, applying no electric field to a dispersal system. Then a displayed image is held.
