Abstract
A plasma display panel driving circuit includes a panel capacitor having first and second sides; a first switch electrically connected between a first voltage and the first side of the panel capacitor; a second switch electrically connected between a second voltage and a first node; a third switch electrically connected between a third voltage and the first side of the panel capacitor; a fourth switch electrically connected between a fourth voltage and the first node; an energy recovery circuit electrically connected between the first side of the panel capacitor and the first node; a fifth switch electrically connected between the first node and a second node; a sixth switch connected between a fifth voltage and the second node; a voltage source connected between the second node and a third node; and a scan IC. The driving circuit can produce driving waveforms that do not need to stay at ground potential.
