Abstract:
1. A method of driving a plasma display panel having a plurality of cells arranged in a matrix type each of said cells including a scan electrode, a sustain electrode and a data electrode, the method comprising: a reset step of making an entire write discharge of the cells to form wall charges; an address step of making an address discharge of specific cells of the cells undergoing said entire write discharge to invert the polarities of the wall charges of said specific cells and to keep the polarities of the wall charges according to said entire write discharge as they are at the remaining cells excluding said specific cells, wherein said specific cells generate an address discharge by a scanning pulse and a data pulse applied to the scan electrode and the data electrode at said address step, and the polarities of the wall charges formed at said specific cells after said address discharge are inverted by a direct current level applied to said sustain electrode; and a sustain step of making a sustain discharge of only the specific cells having the inverted wall charge polarity by a sustain pulse.
