Abstract
A plasma display device. A plasma display panel includes a plurality of address electrodes, a plurality of scan electrodes, and a plurality of sustain electrodes. A temperature detector detects a temperature of the plasma display panel. A controller outputs a scan electrode driving signal to control a reset waveform to be applied during reset periods of a first number of subfields when the detected temperature between a first temperature and a second temperature, and to control a reset waveform to be applied during reset periods of a second number of subfields when the detected temperature is lower than the first temperature and higher than the second temperature. The second number of subfields is greater than the first number of subfields. A scan electrode driver applies the appropriate reset waveform during a reset period of a subfield according to the scan electrode driving signal output from the controller.
