ABSTRACT:
A method and device for driving a plasma display panel are provided that do not cause false lighting even if the all-cell initializing operation becomes unstable. In an initializing period of a subfield, an all-cell initializing operation of causing initializing discharge in all discharge cells or a selective initializing operation of causing initializing discharge in the discharge cell that has caused sustain discharge in the last sustain period is performed. In a field corresponding to an image signal for displaying black on the whole screen, an abnormal charge erasing period for applying rectangular waveform voltage to the scan electrode is disposed after the initializing period in the subfield where the all-cell initializing operation is firstly performed. In a field corresponding to an image signal other than the image signal for displaying black on the whole screen, an abnormal charge erasing period for applying rectangular waveform voltage to the scan electrode is disposed after the initializing period in any subfield after the subfield where the all-cell initializing operation is firstly performed.
