Patent ID: 7701435

Claim:
A method for driving an electrophoretic display, comprising: a first writing step of displaying a first image by applying a first voltage to a plurality of electrophoretic devices; after application of said first voltage to said plurality of electrophoretic devices, a first reset step of erasing said first image by applying a first reset voltage to said plurality of electrophoretic devices, said first reset voltage being of a magnitude that a first afterimage of said first image remains; after said first reset step, a second writing step of displaying a second image by applying a second voltage to said plurality of electrophoretic devices; after said second writing step, a second reset step of erasing said second image by applying a second reset voltage to said plurality of electrophoretic devices, said second reset voltage being equal to said first reset voltage such that a second afterimage of said second image remains; after said second reset step, a third image writing step of displaying a third image by applying a third voltage to said plurality of electrophoretic devices; and after said third image writing step, a third reset step of completely erasing said third image by applying a third reset voltage to said plurality of electrophoretic devices, said third reset voltage being of a greater magnitude than said first and second reset voltages such that no afterimages of said first, second, and third images remain.
