Abstract:
1. A method for driving a plasma display panel having an upper plate on which a scan electrode and a sustain electrode are formed, and a lower plate on which an address electrode is formed, comprising: applying a first initialization signal to the scan electrode and a second initialization signal to the sustain electrode during an initialization period; applying a scan signal to the scan electrode, and data signal to the address electrode during an address period; applying a plurality of sustain signals to the scan electrode and the sustain electrode during a sustain period; and applying a first pre-erase signal to the scan electrode and a second pre-erase signal to the sustain electrode during a pre-erase period between applying the scan signal and applying the sustain signals, wherein the first and the second pre-erase signals decrease gradually from a first voltage to a second voltage.
