A method of driving a plasma display panel is disclosed in which initialization is performed securely and the background light emission is reduced. As an operation for the initialization, an obtuse waveform pulse is applied to all cells three times. In the first obtuse waveform pulse application, discharge is generated only in the previously lit cell, so that the wall voltage thereof approaches the wall voltage in the previously unlit cell. In the second obtuse waveform pulse application, discharge is generated in the previously lit cell and in the previously unlit cell, so that the wall voltage in these cells changes to a value within an appropriate range. In the third obtuse waveform pulse application, discharge is generated in the previously lit cell and in the previously unlit cell, so that the wall voltage of these cells changes to a preset value. <IMAGE> |
