Patent ID: 7642991

Claim:
A method for driving an AC type plasma display panel having a screen including a plurality of cells, each cell being defined at a respective intersection of a pair of first and second display electrodes arranged in a row direction and an address electrode arranged in a column direction, the method comprising: performing initialization at least once for each frame so as to clear binary setting of wall charge quantity in the screen by applying a ramp waveform pulse between the first and second display electrodes; and performing special initialization at frequency of once for every M frames, where M is two or more, so as to erase unnecessary wall charges in the screen by applying at least one of a first rectangular waveform pulse between the first display electrodes and the address electrode, and a second rectangular waveform pulse between the second display electrodes and the address electrode, the first rectangular waveform pulse and the second rectangular waveform pulse being applied with a polarity in which the address electrode becomes a cathode, causing a discharge that is stronger than a discharge in the initialization, between the at least one of the first display electrodes and the address electrode, and the second display electrodes and the address electrode, respectively.
