Patent ID: 7375702

Claim:
A method for driving a plasma display panel in which plural first and second electrodes in parallel to each other are arranged adjacently by turns, and plural third electrodes are arranged in a direction perpendicular to the first and second electrodes, and discharge cells defined at crossings of each electrode are arranged in a matrix, comprising: a reset period in which a wall charge distribution of wall charges in the plural discharge cells is initialized; an address period in which distribution of wall charges according to display data is formed by address discharges, consisting of a first half of the address period in which scan pulses are sequentially applied to electrodes of one group of odd-numbered second electrodes and one group of even-numbered second electrodes, and address pulses according to the display data are applied to the third electrodes, and a second half of the address period in which scan pulses are sequentially applied to electrodes of the other of odd-numbered second electrodes and the even-numbered second electrodes, and address pulses according to the display data are applied to the third electrodes; and a sustain discharge period in which sustain discharges are caused to occur according to the distribution of wall charges formed in the address period; wherein a potential difference between a second electrode of the other of the odd numbered second electrodes and a third electrode, which causes the address discharge in the second half of the address period is set to a value larger than a potential difference between a second electrode of the odd-numbered second electrodes group and the even-numbered second electrodes group and a third electrode, which causes the address discharge in the first half of the address period.
