ABSTRACT:
The present invention provides a novel energy recovery circuit for an AC plasma display device. The circuit includes a series connection of a load capacitance in a display panel, an inductor to recover most of energies normally lost in charging and discharging the load capacitance and a two way switching device comprising a pair of n-channel MOS transistors connected in series to each other so that a line, on which charging and discharging current flow, includes no diode nor resistive element thereby the circuit is free from any unnecessary parasitic capacitance.
