A driving method for a plasma display panel comprising scan electrodes, sustain electrodes, and address electrodes, the scan electrodes and the sustain electrodes crossing the address electrodes at discharge cells, wherein the plasma display panel is configured to display an image during a frame comprising a plurality of subfields, each subfield comprising a reset period, an address period, and a sustain period, the driving method comprising:
- applying a signal gradually rising to a first voltage to the scan electrodes during a first period of the sustain period;
- and
- applying a pulse having a second voltage to the sustain electrodes during the first period.
A driving method for a plasma display panel (PDP) comprising a plurality of discharge cells, wherein the PDP is configured to display an image during a frame comprising a plurality of subfields, each subfield comprising a reset period, an address period, and a sustain period, the driving method comprising:
- uniformly distributing wall charges over the discharge cells during the reset period;
- selecting discharge cells from the plurality of discharge cells to be turned on during the address period;
- and
- causing a sustain discharge in the discharge cells during the sustain period, the discharge cells being selected during the address period,
- wherein causing the first sustain discharge during the sustain period comprises:
