Abstract
A method for driving a plasma display panel, by alternately applying a first voltage and a second voltage to a panel capacitor formed between a first electrode and a second electrode. A first switch and a second switch coupled between a first terminal of the panel capacitor and a first power source for supplying the first voltage are turned off. A second voltage is applied to the first terminal of the panel capacitor. A first electric path between a contact of the first switch and the second switch, and a third voltage is formed. The third voltage being a voltage between the first voltage and the second voltage, where a first capacitor formed between both terminals of the first switch has a lower capacitance than a second capacitor formed between both terminals of the second switch.
