Patent ID: 7372432

Claim:
A switching device for driving a plasma display panel having a plurality of address electrodes, a plurality of scan electrodes and a plurality of sustain electrodes arranged in pairs, and panel capacitors formed between the plurality of address electrodes, and between the plurality of scan electrodes and the plurality of sustain electrodes, the switching device comprising: a first insulated gate bipolar transistor for performing turning on or turning off operations by a voltage applied to a gate of the first insulated gate bipolar transistor; and a second insulated gate bipolar transistor, coupled in parallel to the first insulated gate bipolar transistor, for performing the turning on or turning off operations by a voltage applied to a gate of the second insulated gate bipolar transistor, wherein the first insulated gate bipolar transistor and the second insulated gate bipolar transistor are disposed on a current path between a power source and an electrode of a panel capacitor.
