Abstract:
1. A method of driving a bistable electro-optic display having a plurality of pixels, the method comprising: storing data representing at least an initial state of each pixel of the display; storing first and second look-up tables; receiving an input signal representing a desired final state of at least one pixel of the display; and generating an output signal representing the impulse necessary to convert the initial state of said one pixel to the desired final state thereof, as determined from said look-up tables, wherein said second look-up table stores a plurality of standard waveforms, each of said plurality of standard waveforms having at least one parameter, and said first look-up table stores, for each combination of initial state and final state of a pixel, a pointer denoting which of the standard waveforms in the second look-up table is to be used for the transition from the initial state to the final state, and the value or values of the at least one parameter to be used in this standard waveform.
