ABSTRACT:
A plasma display device and a driving method thereof are provided. The plasma display device has a panel having a plurality of discharge cells including a display electrode pair that is formed of a scan electrode and a sustain electrode, and a temperature detecting circuit for detecting the ambient temperature of the panel and outputting the detected temperature. In the driving method, an unusual charge erasing period when a rectangular waveform voltage is applied to the scan electrode is disposed between the initializing period and address period of at least one of a plurality of subfields, and the number of subfields having the unusual charge erasing period is controlled based on the detected temperature detected by the temperature detecting circuit.
