Abstract:
A driving apparatus for a plasma display panel with a pulse generator to supply an alternating pulse to an electrode, and an energy recovering unit to store charges from a discharge cell when the pulse voltage decreases or to output the stored charges to the discharge cell when the pulse voltage increases. The energy recovering unit has a magnetic switch, coupled with the discharge cell and an energy storage capacitor, with variable inductance to control transient time when the pulse transitions from a first voltage to a second voltage. The transient time is based on LC resonance of the magnetic switch inductance and panel capacitance, and can be reduced to improve resolution of the panel. Insulated gate bipolar transistors can be used with the magnetic switches to reduce power loss during switching and in the on-state, and can sustain high voltages necessary for high concentration Xe discharge gas.

Abstract:
A plasma discharge method and a plasma display using the same. In the method, a sustain discharge uses a facing surfaces discharge and a surface discharge after an address discharge. The discharges occur in separate discharge areas, and priming particles generated by the discharges are exchanged. Thus, the stability and the efficiency of the sustain discharge increase, and a gap for the address discharge decreases to lower a breakdown voltage.
