摘要： A plasma display panel driving method and a plasma display apparatus are disclosed in which a suitable address discharge can be performed at a next scanning timing by reducing voltage changes in a sustain electrode and a scan electrode caused by a change of an address pulse when the address pulse is applied to an address electrode at a scanning timing. The plasma display panel driving method drives a plasma display panel which includes plural scan electrodes extending in a first direction and plural address electrodes extending in a second direction orthogonal to the first direction. In the method, a negative polarity scan pulse is applied to a scan electrode, a positive polarity address pulse is applied to an address electrode from an address electrode driving circuit, and an address discharge is generated. The positive polarity address pulse is generated by using a charge sharing system, in which before clamping a predetermined high voltage or a predetermined low voltage to the address electrode, an averaged voltage generated from electric charges remaining in the plural address electrodes is applied to the address electrode. A falling time of the address pulse is longer than a rising time of the address pulse.
