Abstract:
1. A method for driving a plasma display comprising a plurality of first electrodes having at least a first group and a second group, a plurality of second electrodes crossing the plurality of first electrodes, and a plurality of cells comprising first group cells and second group cells, the method comprising: initializing the first group cells corresponding to the first electrodes of the first group during a first period; selecting first group light emitting cells from the first group cells during a second period; during a third period, sustain-discharging the first group light emitting cells selected during the second period; initializing the second group cells corresponding to the first electrodes of the second group during a fourth period; selecting second group light emitting cells from the second group cells during a fifth period; and during a sixth period, sustain-discharging the second group light emitting cells selected during the fifth period, wherein the initializing of the first group cells comprises applying a first waveform gradually increasing from a first voltage to a second voltage and gradually decreasing to a third voltage to the first electrodes of the first group, and applying a second waveform gradually increasing to a fourth voltage and gradually decreasing to a fifth voltage to the first electrodes of the second group, and the second voltage is higher than the fourth voltage, and wherein the initializing of the second group cells comprises applying the first waveform to the first electrodes of the second group and applying the second waveform to the first electrodes of the first group during the fourth period, and the first group cells are not initialized during the fourth period.
