ABSTRACT:
A switching device for a plasma display panel that facilitates operations at a high voltage. The switching device may be formed with more than one insulated gate bipolar transistors (IGBT) coupled in parallel. The switching device may also be formed with an insulated gate bipolar transistor and a metal-oxide semiconductor field effect transistor (MOSFET) coupled in parallel. The MOSFET may be used for the switching device in a low current area and the IGBT may be used for the switching device in a high current area.
