Abstract
A method for driving an AC type plasma display panel includes the steps of performing initialization at least once for each frame so as to clear binary setting of wall charge quantity in a screen by discharge except for micro discharge in which electrodes covered with a plurality of fluorescent materials become cathodes, and performing special initialization at frequency of once for M frames, where M=two or more, so as to erase unnecessary wall charge in the screen by discharge in which electrodes become cathodes and that is stronger than the discharge in the initialization.
