Plasma display apparatus

A plasma display apparatus comprising:

• a plasma display panel including a front substrate on which a scan electrode and a sustain electrode are positioned parallel to each other, a rear substrate on which an address electrode is positioned to cross the scan electrode and the sustain electrode, and a barrier rib that is positioned between the front substrate and the rear substrate to partition a discharge cell;
• and
• a driver that supplies a sustain signal to the scan electrode and the sustain electrode in a sustain period of at least one of a plurality of subfields of a frame,
• wherein the sustain signal includes a rising period during which a voltage of the sustain signal rises, a hold period during which the voltage is held at a maximum voltage, and a falling period during which the voltage falls,
• wherein a rising period of a sustain signal supplied to the scan electrode overlaps a falling period of a sustain signal supplied to the sustain electrode in the sustain period, and a falling period of the sustain signal supplied to the scan electrode overlaps a rising period of the sustain signal supplied to the sustain electrode in the sustain period,
• wherein the address electrode is electrically floated in the sustain period.
