Patent ID: 7230588

Claim:
A plasma display device operative during a frame comprising a sequence of subfields, each said subfield having a reset period during which a main reset waveform or an auxiliary reset waveform is applied, the plasma display device comprising: a plasma display panel having a plurality of discharge cells, a plurality of address electrodes, a plurality of scan electrodes, and a plurality of sustain electrodes; a temperature detector adapted to detect a temperature of the plasma display panel; a controller adapted to output a scan electrode driving signal to control the main reset waveform to be applied during reset periods of a first number of the subfields when the detected temperature is between a first temperature and a second temperature, and to control the main reset waveform to be applied during the reset periods of a second number of the subfields when a detected temperature is lower than the first temperature or higher than the second temperature, the second number of subfields being greater than the first number of subfields; and a scan electrode driver adapted to apply the reset waveforms during the reset periods of the subfields according to the scan electrode driving signal output from the controller.
