Abstract
A driver circuit for plasma display panels is provided. The claimed 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 ground and the X side of the equivalent capacitor, for passing current of charging/discharging the equivalent capacitor from the X side and/or Y side; and a second unit, coupled to the first unit and the Y side of the equivalent capacitor, for passing current of charging/discharging the equivalent capacitor from the Y side. With the aid of four voltage sources, it is not necessary for the present energy recovery circuit of the driver circuit to adopt capacitors for charging/discharging the equivalent capacitor of the plasma display panel.
