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 thence to a third image, different from both the transition image and the second image, using the first drive scheme.
Claims15
A method of operating an electro-optic display using first and second drive schemes differing from each other and at least one transition drive scheme different from both the first and second drive schemes, the method comprising, in this order:
- driving the display to a first image using a first drive scheme;
- driving the display to a second image, different from the first image, using a transition drive scheme;
- driving the display to a third image, different from the second image using a second drive scheme;
- driving the display to a fourth image, different from the third image, using the transition drive scheme;
- and
- driving the display to a fifth image, different from both the third and fourth images, using the first drive scheme.
