PLASMA DISPLAY APPARATUS

A plasma display apparatus is disclosed. The plasma display apparatus 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 supplying 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. A sustain signal supplied to the scan electrode overlaps a sustain signal supplied to the sustain electrode in the sustain period. The address electrode is electrically floated in the sustain period.
