Patent ID: 7852287

Claim:
A drive method for driving a plasma display panel that has plural pairs of first and second electrodes extending parallel to each other, a plurality of third electrodes extending orthogonally to the pairs of first and second electrodes, and cells formed where the electrodes intersect orthogonally, the drive method driving the plasma display panel by applying a scan pulse sequentially to the first electrodes and a data pulse selectively to the third electrodes in a write period, in order to generate a write discharge selectively in the plurality of cells, and illuminating a written cell in a sustain period that succeeds the write period, wherein when the scan pulse is applied to the first electrodes in the write period, a write auxiliary discharge of smaller magnitude than the write discharge is generated at least in a cell selected for writing or in a cell positioned adjacent to the selected cell; and in the write period, an auxiliary pulse is applied to a third electrode in a cell other than the selected cell, at the same time that the scan pulse is applied to the first electrodes, the auxiliary pulse having the same polarity as the data pulse.
