Abstract
A method for driving a plasma display panel. The plasma display panel includes a plurality of Y electrodes, a plurality of X electrodes, and a plurality of address electrodes. The Y electrodes are divided into a plurality of groups according to an order for scanning the Y electrodes and scan voltages are established to be varied for different groups when the scan voltages are sequentially applied to the Y electrodes. A period for gradually reducing a voltage at the Y electrodes and a bias voltage at the X electrodes is further included when the scan voltages are applied to the first Y electrode of each group of Y electrodes.
