Abstract:
1. A driver for a plasma display panel including discharge cells with a plurality of electrodes, comprising: a first voltage source having a first voltage level; a first switch coupled between the first voltage source and an electrode; a first active element for cutting off a current flowing in the direction of the first voltage source through the first switch; a capacitor for storing a second voltage; and a second switch coupled between the capacitor and the electrode, and for turning on in a reset period to supply the second voltage stored in the capacitor to the electrode, wherein the first voltage source, the first switch, the first active element, and the electrode form a first current path, and wherein the first voltage source, the capacitor, the second switch, and the electrode form a second current path, and the first switch and the first active element are not on the second current path.
