ABSTRACT:
A method for driving a PDP is disclosed, and is capable of suppressing an erroneous discharge during an address discharge and sustain discharge and of preventing deterioration in image quality, comprising: a reset period for initialization; an address period having a first half of the address period in which one of odd-numbered and even-numbered second electrodes are first scanned sequentially, and address pulses are applied to third electrodes, and a subsequent second half of the address period in which others of the odd-numbered and the even-numbered second electrodes are scanned sequentially, and address pulses are applied to the third electrodes; and a sustain discharge period in which sustain discharges are caused to occur, wherein the potential difference between the second electrode and the third electrode in the second half of the address period is set to a value larger than the potential difference between the second electrode and the third electrode in the first half of the address electrode.
