PROBLEM TO BE SOLVED: To provide a method of driving an electrooptic display, especially a bistable electrooptic display, and to provide a device used in such a method. SOLUTION: Waveforms for driving an electrooptic display, especially a bistable electrooptic display, are modified by one or more of insertion of at least one balanced pulse pair into a base waveform; excision of at least one balanced pulse pair from the base waveform; and insertion of at least one period of zero voltage into the base waveform. Such modifications permit fine control of gray levels. Two pulses of the balanced pulse pair have each a constant voltage, polarities opposite to each other, and durations equal to each other.
