Abstract:
1. A method for driving a plasma display panel having a plurality of first electrodes and a plurality of second electrodes, and a plurality of third electrodes formed crossing the first electrodes and the second electrodes, wherein a discharge cell is defined by a first electrode, a second electrode, and a third electrode, and a frame is divided into a plurality of subfields, the plurality of first electrodes being divided into a plurality of groups, a subfield including a plurality of sustain periods and a plurality of address periods corresponding to the respective groups, the method comprising: in a first subfield of a first frame, selecting turn-on discharge cells among discharge cells of a first group of first electrodes by performing an address operation for the first group, and performing a sustain discharge for selected discharge cells; and after performing the sustain discharge for the selected discharge cells, selecting turn-on discharge cells among discharge cells of a second group of first electrodes by performing an address operation for the second group, and performing a sustain discharge for selected discharge cells; and in a first subfield of a second frame, selecting turn-on discharge cells among discharge cells of the second group by performing an address operation for the second group, and performing a sustain discharge for selected discharge cells; and after performing the sustain discharge for the selected discharge cells, selecting turn-on discharge cells among discharge cells of the first group by performing an address operation for the first group, and performing a sustain discharge for selected discharge cells.
