Abstract
There are provided methods for driving an electro-optic display having a plurality of display pixels, a such method includes detecting a white-to-white graytone transition on a first pixel; and determining whether a threshold number of cardinal neighbors of the first pixel are not making a graytone transition from white to white, or if the first pixel is a color pixel, and apply a first waveform.
