Abstract
Methods for improved partial updates in color electrophoretic displays. By identifying transition borders between pixels receiving null updates (no voltage sent to pixel electrode) and color updates, problematic pixels, which would have received null updates, are caused to update to a same color state, thereby reducing edge ghosting in the updated image and improving the color in the updated image.
