    • A plasma display device including a first electrode, a second electrode, and a third electrode crossing the first electrode and the second electrode is disclosed. A plurality of first sustain pulses are applied to the first electrode and a plurality of second sustain pulses are applied to the second electrode during a sustain period of a first subfield. A voltage at the first electrode gradually decreases from a third voltage to a fourth voltage after the voltage at the first electrode gradually increases from a first voltage to a second voltage, during a sub-reset period of a second subfield being consecutive to the first subfield. The plurality of second sustain pulses includes a first group and a second group, the second group includes the last one of the second sustain pulses, and a second sustain pulse of the second group has a different characteristic (e.g., pulse width) from a second sustain pulse of the first group.

    • A plasma display device including first and second electrodes and a driving circuit alternately applying first and second voltages to the first and second electrodes. The driving circuit includes a power recovery unit, a sustain discharge voltage supply, and a gate voltage supply. The power recovery unit includes an inductor coupled between the first electrode and a capacitor, and increases/decreases the voltage of the first electrode by electrically coupling the inductor and the capacitor. The sustain discharge voltage supply includes a first transistor and a second transistor that couple the first electrode to a supply voltage and to ground. In case of damage to a circuit element, a current is established, through a Zener diode, coupled between the capacitor and the gate voltage supply, that disconnects the supply of voltage to gate drivers of the circuit transistors and stops the operation of the driving circuit.
