Embodiment Construction
[0089] As indicated above, the present invention provides data structures and methods for operating bistable electro-optic displays. The data structure and manipulation methods allow multiple drive schemes to be used simultaneously in the display. In preferred forms of the data structures and methods of the present invention, multiple drive scenarios can be started at different times and thus run independently of each other.
[0090] The multiple driving schemes used in the preferred form of the method can start at different times, and this does not imply that any given driving scheme can start at any arbitrary time; certain restrictions. As discussed in the previous MEDEOD application, the vast majority of high resolution displays use an active matrixbackplane, with pixel electrodes arranged in a two-dimensional matrix defined by row and column electrodes. The row driver selects one row of pixel electrodes at a time and applies appropriate voltages to the column electrodes...

Abstract
A data structure for use in controlling a bistable electro-optic display having a plurality of pixels comprises a pixel data storage area (106', 108') 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 (HO') storing data representing at least all the drive schemes denoted by the drive scheme index numbers stored in the pixel data storage area (106', 108'). A corresponding method of driving a bistable electro-optic display using such a data structure is also provided.
