ABSTRACT:
In a drive scheme for driving the pixels of a passive matrix liquid crystal display having row and column electrodes, the drive scheme including a selection step, the selection step including applying row and column waveforms to the display to generate selected pixel voltage pulses in a selected row and to generate non selected pixel voltage pulses in non selected rows, the selection step having an effective selection time that depends on the preceding and following nonselected pixel voltages, a framing voltage pulse is inserted between each successive selected pixel voltage pulse such that the effective selection time is independent of the preceding and following nonselected pixel voltages, whereby data pattern dependent defects in a displayed image are eliminated.
