A plasma display apparatus comprises a plasma display panel, a temperature detector and driver. The plasma display panel comprises a plurality of first electrodes and a plurality of second electrodes formed in parallel to each other. The temperature detector for detecting a temperature of the plasma display panel to output a temperature information signal. The driver which receives the temperature information signal from the temperature detector, and if the temperature of the plasma display panel is lower than a reference temperature, clamps a first sustain signal, which is supplied to at least one of the first electrodes and second electrodes, at a first clamping time, and if the temperature of the plasma display panel is higher than the reference temperature, clamps a second sustain signal, which is supplied to at least one of the first electrodes and the second electrodes, at a second clamping time different from the first clamping time.
