Patent ID: 7602355

Claim:
A plasma display apparatus comprising: a scan electrode: a sustain electrode; and a controller for applying a rising waveform and a falling waveform to the scan electrode in a reset period of a first subfield of a frame and the controller for applying another falling waveform to the scan electrode when a first time elapses, after a first sustain voltage is applied to the scan electrode during a sustain period of the first subfield, wherein a second sustain voltage is applied to the sustain electrode during the sustain period when a second time elapses after the first sustain voltage is applied, wherein the first sustain voltage and the second sustain voltage are continuously applied at an end of the sustain period of the first subfield, wherein the controller is adapted to apply a sub rising waveform, which rises from the first sustain voltage, to the scan electrode between an application time point of the first sustain voltage and an application time point of the other falling waveform, wherein a peak voltage value of the sub rising waveform is different from a peak voltage value of the sub rising waveform in other subfields, and wherein the sub rising waveform has a higher peak voltage value in higher grey level subfields.
