Abstract

A PDP driving apparatus drives a plasma display panel (PDP) having sustain electrodes, scan electrodes, and address electrodes. The PDP driving apparatus includes a high side switch element and a low side switch element, those electrically coupled in series. A specific pulse voltage is applied from a junction point of the high side switch element and the low side switch element to at least sustain electrodes, scan electrodes, or address electrodes of the plasma display panel. At least one of the high side switch element and the low side switch element is a bidirectional switch element.
