Patent ID: 7592978

Claim:
A method for driving a plasma display panel in at least a reset period and a sustain period, the plasma display panel comprising a first electrode, a second electrode and a third electrode between the first electrode and the second electrode, the method comprising: during the sustain period, alternately applying a sustain pulse to the first electrode and the second electrode while maintaining the third electrode at a substantially fixed voltage; and during a period of the reset period, said period being immediately after the sustain period: (a) applying a positive pulse voltage waveform comprising a first voltage and a second voltage to the third electrode; (b) applying a third voltage, which is not less than the first voltage and also not less than the second voltage, to the first electrode while the positive pulse voltage waveform is applied; (c) maintaining the first electrode at the third voltage for a time period longer than a pulse width of the positive pulse voltage waveform; (d) applying a fourth voltage, which is not less than the first voltage and also not less than the second voltage, to the second electrode while the positive pulse voltage waveform is applied; and (e) maintaining the second electrode at the fourth voltage for a period longer than the pulse width of the positive pulse voltage waveform.
