Abstract

Official abstract text for this publication.

A method for driving an electrophoresis display device includes applying a reset voltage having a first polarity to electrophoresis material of the display device for at least one frame period to display a reset image, applying a first gradation voltage having a second polarity opposite to the first polarity to the electrophoresis material for one frame period to display a first grey image after the reset image is displayed, applying a second gradation voltage having the second polarity to the electrophoresis material corresponding to at least one pixel region of the display device for at least two frame periods to display a second grey image, after the first grey image is displayed; and applying a third gradation voltage having the first polarity to the electrophoresis material corresponding to at least one pixel region for one frame period to display a third grey image, after the second grey image is displayed.
