Abstract
Disclosed is a method of driving a plasma display panel enabling to improve an overall contrast characteristic of the plasma display panel by reducing a voltage difference between scan and sustain electrodes Y and Z to decrease an emission amount of light generated by a discharge between the scan and sustain electrodes Y and Z. The present invention includes a first step of applying a reset pulse to the scan electrode to form predetermined wall charges on the electrodes for a set-up period and a second step of applying a pulse of a predetermined level to the sustain electrode to reduce a voltage difference between the scan and sustain electrodes while the reset pulse is applied.
