Abstract:
1. 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, comprising the steps of: (a) applying scanning pulses in time-division to said scanning electrodes in an addressing period in which a cell or cells emitting light is(are) selected, and applying sustaining pulses to said sustaining electrodes in a sustaining period for generating preliminary discharge and preliminary erasing discharge before said cell or cells emitting light is(are) selected; and (b) applying a serrate pulse to said scanning or sustaining electrodes when said preliminary erasing discharge is generated, said serrate pulse having an inclination smaller than 10 V/μs, wherein a period of time until the generation of said preliminary erasing discharge from the termination of said preliminary discharge is set shorter than 3T where T indicates a decay time constant of priming particles.
