Abstract:
1. A method of driving a plasma display panel, the method comprising: providing a plasma display panel including a plurality of scan electrodes, a plurality of sustain electrodes, a plurality of data electrodes extending to a direction crossing to the scan and the sustain electrodes, and a plurality of discharge cells defined by the scan electrodes, the sustain electrodes, and the data electrodes, the discharge cells being divided into discharge cell groups including a first discharge cell group and a second discharge cell group, dividing one TV field into a plurality of subfields; performing a reset operation by applying a first reset waveform and a second reset waveform subsequent to the first reset waveform to at least one of the discharge cells, the reset operation being performed during only a first subfield among the plurality of subfields; applying a first sustain discharge pulse to the scan electrodes in a second subfield among the plurality of subfields; selecting a discharge cell for an address erasure among the first discharge cell group after said applying the first sustain discharge pulse; and applying a second sustain discharge pulse to the scan electrodes in the second subfield after said selecting said discharge cell for the address erasure.
