Abstract
To provide an AC-PDP capable of achieving low power consumption and low cost, a driving method is adopted in which, during a period of sustaining light emission of the AC-PDP, an electrode of one side of the panel is fixed at a predetermined potential, and positive and negative voltages are alternately applied to an electrode of the other side of the panel. In addition, an IGBT is used as a switch element. Thus, with a half-bridge driving method using an IGBT as a switch element, it is possible to simultaneously achieve a reduction in loss of a driving circuit of the AC-PDP and a reduction in the number of components thereof, such reductions not being able to be achieved by the conventional techniques.
