Abstract:
A device for driving a plasma display panel having a plurality of scan electrodes and sustain electrodes alternately arranged in pairs, wherein a panel capacitor is formed between a scan electrode and a sustain electrode pair, the device comprising:a first sustain and discharge unit coupled to a first electrode of the panel capacitor, and coupled between a first power source for supplying a first voltage and a second power source for supplying a second voltage, for operating so that the first electrode is maintained to be one of the first and the second voltages; a second sustain and discharge unit coupled to a second electrode of the panel capacitor, and coupled between the first power source and the second power source so that the second electrode is maintained to be one of the first and the second voltages; and a charge and discharge unit including at least one inductor coupled to the panel capacitor, for converting a voltage at the second electrode into the second voltage to store energy in the inductor, using the energy stored in the inductor to convert the voltage at the first electrode into the first voltage, converting the voltage at the first electrode into the second voltage to store energy in the inductor, and using the energy stored in the inductor to convert the voltage at the second electrode into the first voltage.
