ABSTRACT:
A plasma display panel driving method and a plasma display device capable of reducing initializing spots generated immediately after the start of driving the plasma display panel, and improving the quality of images to be displayed. A plurality of subfields, each including an initializing period, an address period, and a sustain period, are provided in one field. The one field includes at least one of the subfields in which a gently increasing ramp waveform voltage is applied to the scan electrodes in the initializing period thereof. The ramp waveform voltage to be applied to the scan electrodes for the first time after the start of driving the plasma display panel is generated so as to have a gentler slope than the other ramp waveform voltages have.
