Patent ID: 7463221

Claim:
A plasma display device for displaying an image during a frame comprising a plurality of subfields, said plasma display device comprising: a plasma display panel comprising a plurality of discharge cells for displaying the image, a plurality of address electrodes, a plurality of scan electrodes, and a plurality of sustain electrodes; and a scan electrode driver adapted to apply a reset waveform during a reset period to at least one of the scan electrodes, said reset waveform comprising a main reset waveform or an auxiliary reset waveform having a waveform different from the main reset waveform, wherein the scan electrode driver is adapted to apply a first number of at least one said main reset waveform to the at least one of the scan electrodes during the frame when a peripheral temperature of the plasma display panel is higher than a first temperature, and to apply a second number of at least one said main reset waveform to the at least one of the scan electrodes during the frame when the peripheral temperature of the plasma display panel is less than or equal to the first temperature, the first number being larger than the second number.
