Patent ID: 7385569

Claim:
A plasma display panel driving circuit comprising: a panel equivalent capacitor having a first side and a second side; a first switch electrically connected between a first voltage source and the first side of the panel equivalent capacitor; a second switch electrically connected between a second voltage source and a first node; a third switch electrically connected between a third voltage source and the first side of the panel equivalent capacitor; a fourth switch electrically connected between a fourth voltage source and the first node; an energy recovery circuit electrically connected between the first side of the panel equivalent capacitor and the first node; a fifth switch electrically connected between the first node and a second node; a sixth switch electrically connected between a fifth voltage source and the second node; a sixth voltage source electrically connected between the second node and a third node; and a scan IC comprising: a high-side switch electrically connected between the third node and the second side of the panel equivalent capacitor; and a low-side switch electrically connected between the second side of the panel equivalent capacitor and the second node.
