<p>The present invention relates to a plasma display apparatus, and more particularly, to a plasma display apparatus and driving method thereof, wherein a sustain waveform of a positive polarity and a sustain waveform of a negative polarity are applied upon driving of the apparatus. According to the present invention, the plasma display apparatus includes a plasma display panel in which a plurality of sustain electrodes having scan electrodes and common electrodes is formed, a driving unit for driving the plurality of the sustain electrodes, and a driving pulse controller for controlling the driving unit to apply a scan waveform of a negative polarity to the scan electrodes during an address period, and a sustain waveform of a positive polarity and a sustain waveform of a negative polarity, which has the same voltage as that of the scan waveform, to the scan electrodes during a sustain period, and to apply sustain waveforms having an opposite polarity to the sustain waveform of the positive polarity and the sustain waveform of the negative polarity, which are applied to the scan electrodes, to the common electrodes during the sustain period. As such, since a low voltage is used, power consumption can be saved, efficiency can be increased, and the load of a high voltage to a driving circuit can be curtained.</p> |
