A driver circuit for plasma display panels is provided. The driver circuit includes four 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 the equivalent capacitor, 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, for passing current of charging and/or discharging the equivalent capacitor from the Y side; and a third unit coupled to the first unit, the second unit and ground, the third unit comprising a capacitor, capable of charging and/or discharging the equivalent capacitor from the X side and/or the Y side.
