Patent ID: 7839358

Claim:
A plasma display panel driving circuit for a plasma display panel comprising a plurality of address electrodes, a plurality of pairs of a scan electrode and a sustain electrode alternately arranged, and a panel capacitor formed among the scan electrode, the sustain electrode, and the address electrode, the plasma display panel driving circuit comprising: an inductor having a first terminal coupled to a third voltage source via a third switch or a fourth switch, and a second terminal coupled to a first terminal of the panel capacitor at a first node; a first switch coupled between the first node and a first voltage source; and a second switch coupled between the first node and a second voltage source, wherein the plasma display driving circuit is configured to: turn on the third switch in a first period while the first switch is off, the second switch is on, and the first node is substantially maintained at a voltage of the second voltage source; turn off the second switch in a second period while the first switch remains off and the third switch remains on; turn on the first switch in a third period while the second switch remains off and the third switch remains on; and turn off the third switch in a fourth period while the first switch remains on and the first node is substantially maintained at a voltage of the first voltage source, wherein a voltage at the first node increases from the voltage of the second voltage source to the voltage of the first voltage source while the third switch continuously remains on.
