Abstract
A method for driving a PDP which can realize higher image quality and lower costs and a plasma display apparatus therefor are provided. A pulse having an interval during which a pulse voltage changes gradually and another interval during which the pulse voltage changes steeply is generated as a reset pulse applied for allowing a discharge cell of the PDP to reset-discharge. In this instance, in the interval during which the pulse voltage changes gradually, a voltage applied to the discharge cell is allowed to reach a minimum reset-discharge starting voltage.
