ABSTRACT:
The present invention relates to a plasma display panel, and more particularly, to a plasma display apparatus and driving method thereof, in which power consumption can be reduced and contrast can be improved, so that a high contrast image can be displayed. The plasma display apparatus according to the present invention comprises 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 applying the 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. The sustain electrode is applied with a second sustain voltage when a second time is elapsed, after the first sustain voltage is applied.
