Patent ID: 8044883

Claim:
A method of driving a plasma display apparatus having a scan electrode and a sustain electrode, the method comprising: applying a ramp-up pulse having a gradually rising voltage to a first electrode during a reset period of a first subfield of a frame, applying, after a last sustain pulse during a sustain period of the first subfield of the frame, a first reset pulse to the first electrode, which is one of the scan electrode and the sustain electrode, during a reset period in a second subfield successive to the first subfield, the first reset pulse having a positive polarity; applying a second reset pulse to a second electrode, which is the other one of the scan electrode and the sustain electrode, during the reset period in the second subfield, after the application of the first reset pulse, the second reset pulse having a positive polarity; and applying a falling ramp pulse that gradually falls from a ground voltage to a negative voltage to the first electrode after the application of the second reset pulse during the reset period in the second subfield, and wherein each of the first reset pulse and the second reset pulse has a rectangular waveform, each maximum voltage of the first reset pulse and the second reset pulse is equal to a maximum voltage of the last sustain pulse, and each width of the first reset pulse and the second reset pulse is less than a width of the last sustain pulse.
