Abstract
Method and apparatus are provided for driving segments of a bistable display. The method may include providing, at the same time, a plurality of independent waveforms corresponding to display data for driving a plurality of segments of the display. The method may include selecting, for each segment, one of the independent driving waveforms. The method may also include determining whether an update of display data has occurred for one of the segments. The method may include selecting a different one of the waveforms to drive the segment if an update has occurred. The method may further include maintaining a currently selected waveform to drive the segment if an update has not occurred.
