Abstract
A method is provided for driving electro-optic displays, especially bistable displays, to avoid edge effects when driving a limited area of the display. Pixels in an edge elimination region, at least one pixel wide and substantially surrounding the limited area, are driven from their original gray level to an intermediate gray level, and then back to their original gray level.
Claims5
A method of driving an electro-optic display having a plurality of pixels, the method comprising applying a local drive scheme to change the optical state of at least one limited area of the display and driving pixels in an edge elimination region, at least one pixel wide and substantially surrounding the at least one limited area, from their original gray level to an intermediate gray level, and then back to their original gray level.
