Method of driving plasma display panel and plasma display apparatus driven by the method

A plasma display apparatus comprising:

• a plasma display panel having a first substrate and a second substrate being separated from and facing each other;
• discharge cells being discharge spaces located between the first substrate and the second substrate;
• X electrodes and Y electrodes extending in parallel across the discharge cells;
• address electrodes extending across the discharge cells crossing a direction of the X electrodes and the Y electrodes at the discharge cells;
• and
• a panel driver that applies driving signals to the X electrodes, the Y electrodes, and the address electrodes,
• wherein the driving signals are applied during unit frames, each unit frame being divided into a plurality of subfields for displaying a time division grey scale, each of the subfields including a reset period, an address period, and a sustain discharge period,
• wherein the reset period of each of the subfields is either a main reset period for initializing all of the discharge cells or an auxiliary reset period for initializing discharge cells selected during a preceding subfield, and
• wherein an erase pulse is applied to the address electrodes during the auxiliary reset period.
