ABSTRACT:
A plasma display panel (PDP) includes a first plurality of electrodes, a second plurality of electrodes paired with the first plurality of respective electrodes, and a third plurality of electrodes. The PDP further includes a plurality of cells at crossing portions between the first and second pluralities of electrodes and the third plurality of electrodes. In the PDP, a method comprises driving a PDP for displaying a picture on the PDP by dividing a field into a plurality of subfields, and resetting for adjusting charges in the cells in the subfields. The resetting for adjusting charges comprises applying voltage waveforms to the electrodes so that the potential difference applied between the second plurality of electrodes and at least one of the first plurality of electrodes and the third plurality of electrodes for the resetting for adjusting charges in a predetermined one of the subfields is larger than the potential difference applied therebetween for the resetting for adjusting charges in a previous subfield.
