Title: Method for driving plasma display panel

Abstract: Disclosed is a method for driving a plasma display panel in which a plurality of first electrodes and second electrodes are arranged parallel to each other, a plurality of third electrodes are arranged to cross the first and second electrodes, and discharge cells defined with areas in which the electrodes cross mutually are arranged in the form of a matrix. According to the driving method, a reset period is a period during which the distribution of wall charges in the plurality of discharge cells is uniformed. An addressing period is a period during which wall charges are produced in the discharge cells according to display data. A sustain discharge period is a period during which sustain discharge is induced in the discharge cells in which wall charges are produced during the addressing period. The driving method in accordance with the present invention comprises a step of applying a first pulse in which an applied voltage varies with time so as to induce first discharge in the lines defined by the first and second electrodes, and a step of applying a second pulse in which an applied voltage varies with time so as to induce second discharge as erase discharge in the lines defined by the first and second electrodes. These steps are carried out during the reset period.
