Plasma display device and driving method thereof

A plasma display device, comprising:

• 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, a discharge cell being defined by a first electrode, a second electrode, and a third electrode;
• and
• a driver for applying a driving signal to the first electrodes, the first electrodes being divided into a plurality of groups,
• wherein the driver,
• in a first subfield of a first frame including a plurality of sustain periods and a plurality of address periods corresponding to the respective groups of first electrodes,
• selects turn-on discharge cells among discharge cells of a first group of first electrodes by performing an address operation for the first group, and performs a sustain discharge for selected discharge cells;
• and
• after performing the sustain discharge for the selected discharge cells, selects turn-on discharge cells among discharge cells of a second group of first electrodes by performing an address operation for the second group, and performs a sustain discharge for selected discharge cells;
• and
• and in a first subfield of a second frame including a plurality of sustain periods and a plurality of address periods corresponding to the respective groups of first electrodes,
• selects turn-on discharge cells among discharge cells of the second group by performing an address operation for the second group, and performs a sustain discharge for selected discharge cells;
• and
• after performing the sustain discharge for the selected discharge cells, selects turn-on discharge cells among discharge cells of the first group by performing an address operation for the first group, and performs a sustain discharge for selected discharge cells.

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 method comprising:
