Abstract
A method and system for applying addressing voltages to pixels of a display involves receiving input data. The input data includes an indication of an addressing voltage impulse to be applied to a pixel via an electrode. One or more voltage sources are selected, to provide the addressing voltage impulse. The one or more voltage sources each have a pre-selected voltage, The selected one or more voltage sources are electrically connected to an electrode to apply the addressing voltage impulse to the pixel. The invention also provides a method of driving an electro-optic display which uses an intermediate image of reduced bit depth, and a method of driving an electro-optic display which uses a limited number of differing drive voltages, with higher voltage pulses being used before lower voltage pulses.
