Abstract

A method for driving a plasma display panel in which any one of a scanning electrode and a sustaining electrode is shared by neighboring display cells interposed therebetween. At least one condition selected from the group consisting of a voltage of a sustaining pulse, a pulse width of a sustaining pulse, and a pulse applying interval of a sustaining pulse is changed in relation to a polarity of the sustaining pulse. The sustaining pulse is applied to the scanning electrode and sustaining electrode by a predetermined number with relation to an image data during a sustaining period.
