Abstract:
1. A method of driving an electro-optic display, the electro-optic display comprising: a layer of an electro-optic medium; a plurality of pixel electrodes disposed on one side of the layer of electro-optic medium and arranged in a two-dimensional array of rows and columns, each of the pixel electrodes being capable of applying an electric field to the electro-optic medium; a plurality of column electrodes, each column electrode being associated with the pixel electrodes in one column of the two-dimensional array; and a front electrode provided on the opposed side of the layer of electro-optic medium from the pixel electrodes, the method comprising changing the voltage on one column electrode from a first value to a second value different from the first value, thereby causing at least one pixel electrode to cause a change in optical state of the electro-optic medium, wherein the voltage on said one column electrode is first changed from the first value to a third value intermediate the first and second values for a period sufficient to permit charge to flow to or from said one column electrode, and thereafter the voltage on said one column electrode is changed from the third value to the second value.
