ABSTRACT:
The present invention relates to a plasma display apparatus, and more particularly, to a plasma display apparatus and driving method thereof, in which scan electrodes are scanned according to one of a plurality of scan types and a last sustain pulse of sustain pulses applied to scan electrodes or sustain electrodes is controlled. The plasma display apparatus of the present invention comprises a plasma display panel comprising a plurality of scan electrodes, a plurality of sustain electrodes, and a plurality of data electrodes crossing the plurality of scan electrodes and the sustain electrodes, and a controller for scanning the scan electrodes using one of a plurality of scan types in which the order of scanning the plurality of scan electrodes is different in an address period, applies a data pulse to the data electrodes corresponding to one scan type, and controls a difference between an application time point of a last sustain pulse of sustain pulses, which are applied to the scan electrodes or the sustain electrode in a sustain period subsequent to the address period, and a application time point of a reset pulse, which is applied to the scan electrodes in a reset period of a next sub-field, to be greater than a difference between application time points of the two sustain pulses, in at least one of sub-fields of a frame.
