ABSTRACT:
A method of driving a plasma display panel including a plurality of scanning electrodes covered with a dielectric layer, and a plurality of sustaining electrodes covered with a dielectric layer, including the steps of (a) applying scanning pulses in time-division to the scanning electrodes in an addressing period in which a cell or cells emitting light is(are) selected, and applying sustaining pulses to the sustaining electrodes in a sustaining period for generating preliminary discharge and preliminary erasing discharge before the cell or cells emitting light is(are) selected, and (b) applying a serrate pulse to the scanning or sustaining electrodes when the preliminary erasing discharge is generated, the serrate pulse having an inclination smaller than 10 V/μs, wherein a period of time until the generation of the preliminary erasing discharge from the termination of the preliminary discharge is set shorter than 3T where T indicates a decay time constant of priming particles.
