Abstract
An electro-optic display uses first and second drive schemes differing from each other, for example a slow gray scale drive scheme and a fast monochrome drive scheme. The display is first driven to a pre-determined transition image using the first drive scheme, then driven to a second image, different from the transition image, using the second drive scheme. The display is thereafter driven to the same transition image using the second drive scheme; and from then to a third image, different from both the transition image and the second image, using the first drive scheme.
