Abstract
The present invention is related to a plasma display panel, in particular to a plasma display apparatus capable of preventing an error discharge or an error writing of a discharge cell. A plasma display apparatus according to an embodiment of the present invention comprises a plasma display panel including a scan electrode and a sustain electrode; and a controller for applying a negative waveform and a positive waveform to the scan electrode between a reset pulse and a scan pulse having negative polarity, wherein the controller applies a sustain bias voltage to the sustain electrode when the negative waveform is applied to the scan electrode.
