Abstract
A driving circuit, which can realize the driving waveforms for a PDP without staying at ground potential includes having one side, the X side, of an panel equivalent capacitor Cof the PDP coupled directly to ground with the Y side of the equivalent capacitor having a Scan ICconnected to a plurality of switches, each switch coupled to a different voltage source. One of the switches is bi-directional and coupled to ground.
