Abstract
A method is provided for driving a plasma display panel having parallel first and second electrodes, third electrodes crossing the first and second electrodes, and discharge cells with electrodes crossing mutually in the form of a matrix. The method includes a reset period during which distribution of wall charges in the discharge cells is uniformed, an addressing period during which wall charges are produced in the discharge cells according to display data, and a sustain discharge period during which sustain discharge is induced in discharge cells in which wall charges are produced during the addressing period. The driving method includes during the reset period, in lines defined by the first and second electrodes, applying a first pulse, in which an applied voltage varies with time to induce first discharge, and applying a second pulse in which an applied voltage varies with time to induce second discharge as an erase discharge.
