Patent ID: 7808515

Claim:
A method of driving a plasma display panel (PDP), comprising: providing a plurality of X electrodes and a plurality of Y electrodes extending in a first direction, a plurality of A electrodes arranged between the X electrodes and the Y electrodes and extending in a second direction that crosses the plurality of X electrodes and the plurality of Y electrodes, and a plurality of discharge cells arranged in a region where the A electrodes cross the X electrodes and the Y electrodes; and applying a pulse waveform voltage alternating between a low level voltage and a high level voltage to the X electrodes and applying a pulse waveform voltage alternating between the high level voltage and the low level voltage to the Y electrodes during a sustain discharge period when sustain discharging occurs in selected ones of the plurality of discharge cells, wherein a pulse width of a first high level voltage applied to the X electrodes in the sustain discharge period is larger than pulse widths of all other high level voltage pulses applied during the sustain discharge period.
