Abstract
A plasma display device determining whether to perform power recovery in address and sustain periods of each subfield according to the temperature of a plasma display panel. When the temperature is outside of a predetermined temperature range, the address voltage is applied by hard switching to the third electrode in order to select the discharge cell to be displayed among the discharge cells in the address period. The sustain discharge pulse voltage is applied by the hard switching to the first and second electrodes in a first group of the sustain period, the sustain period being divided into at least two groups. The sustain discharge pulse voltage is applied by inductor-capacitor resonance of a power recovery circuit to the first and second electrodes in a second group of the sustain period.
