Methods for driving electro-optic displays
First Claim
1. A data structure for use in controlling a bistable electro-optic display having a plurality of pixels, the data structure comprising:
- a pixel data storage area arranged to store, for each pixel of the display, data representing an initial state of the pixel, data representing a desired final state of the pixel, and a drive scheme index number representing the drive scheme to be applied to the pixel; and
a drive scheme storage area arranged to store data representing a plurality of drive schemes, the drive scheme storage area storing at least all the drive schemes denoted by the drive scheme index numbers stored in the pixel data storage area.

Abstract
A data structure for use in controlling a bistable electro-optic display having a plurality of pixels comprises a pixel data storage area storing, for each pixel of the display, data representing initial and desired final states of the pixel, and a drive scheme index number representing the drive scheme to be applied; and a drive scheme storage area storing data representing at least all the drive schemes denoted by the drive scheme index numbers stored in the pixel data storage area. A corresponding method of driving a bistable electro-optic display using such a data structure is also provided.

13. A method of driving a bistable electro-optic display having a first plurality of pixels, the method comprising:
-
storing, for each pixel of the display, data representing an initial state of the pixel, data representing a desired final state of the pixel, and a drive scheme index number representing the drive scheme to be applied to the pixel; storing data representing a plurality of drive schemes at least equal in number to the different drive scheme index numbers stored for the various pixels of the display; and generating, for at least a second plurality of pixels of the display, output signals representing the impulse to be applied to each of the second plurality of pixels, the output signals being generated, for each of the second plurality of pixels, dependent upon the initial and final states of the pixel, the drive scheme index number and the stored data representing the drive scheme denoted by the drive scheme index number. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
