Claims17
A plasma display apparatus comprising:
- a plurality of scan electrodes and sustain electrodes formed on an upper substrate;
- and
- a plurality of address electrodes formed on a lower substrate,
- wherein the plurality of scan electrodes are divided into two or more groups including first and second groups, and
- wherein at least one of a plurality of subfields constituting a frame comprises a first sustain period during which a sustain discharge occurs in the first group, and a second sustain period during which a plurality of sustain signals are supplied to the first and second groups,
- wherein one or more erase signals are supplied to the first group between two of the plurality of sustain signals supplied to the first group in the second sustain period,
- wherein the erase signal is supplied before the last sustain signal of the plurality of sustain signals.
