ABSTRACT:
A driver circuit for plasma display panels is provided. The claimed driver circuit includes three switches and an energy recovery circuit coupled to an equivalent capacitor of a plasma display panel. The present energy recovery circuit includes a first unit coupled to the X side of an equivalent capacitor and to a first switch, for passing current of charging and/or discharging the equivalent capacitor from the X side; a second unit coupled to the Y side of the equivalent capacitor and to the first switch, for passing current of charging and/or discharging the equivalent capacitor from the Y side; and a third unit coupled to the first switch and ground. The third unit includes a capacitor for charging and/or discharging the equivalent capacitor from the X side and/or the Y side, and a fourth switch coupled to the capacitor in series.
