ABSTRACT:
A method of driving a plasma display panel wherein a selective inversion system is used to perform an address operation. In the method, a reset step makes an entire write discharge of the cells to form wall charges. An address step makes 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. A sustain step makes a sustain discharge of only the specific cells having the inverted wall charge polarity by a sustain pulse. Accordingly, a data is written by the selective inversion addressing method to permit a high-speed driving and to prevent a contrast deterioration.
