Abstract
A plasma display panel (PDP) drive method eliminates crosstalk and allows for high quality image display by preventing erroneous discharge from occurring in an address period. The method includes an address step of writing data by applying an address pulse to a third electrode and a scan pulse Pas1 sequentially to first electrodes, and a sustain step of sustaining an illumination by applying sustain pulses between first and second electrodes after completion of the address step. Furthermore, in the address step, a scan pulse Pas2 of opposite polarity to scan pulse Pas1 is applied to a second electrode in a pair with a first electrode in a selected line (i.e. a line in which scan pulse Pas1 is being applied).
