An apparatus for driving a plasma display panel includes a first signal line and a second signal line for supplying a first voltage and a second voltage, respectively, and a first inductor and a second inductor being to one terminal of a panel capacitor. A first current path is formed from the panel capacitor to the second signal line via the second inductor to reduce a voltage of the panel capacitor from the first voltage to the second voltage. A second current path is formed to recover a current flowing to the second inductor to the first signal line, when the voltage of the panel capacitor is sustained at the second voltage. A third current path is formed from the first signal line to the panel capacitor via the first inductor while the current flowing to the second inductor is recovered, thereby increasing the voltage of the panel capacitor from the second voltage to the first voltage. A fourth current path is formed to recover a current flowing to the first inductor to the first signal line, while the voltage of the panel capacitor is sustained at the first voltage.

1. Field of the Invention
The present invention relates to an apparatus and method for driving a plasma display panel. More specifically, the present invention relates to a driver circuit for plasma display panels.
The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate an embodiment of the invention, and, together with the description, serve to more fully explain the principles of the invention.
FIG. 1 is an illustration of a PDP according to an embodiment of the present invention.
FIG. 2 is a circuit diagram of a power recovery circuit according to the embodiment of the present invention.
In the following detailed description, only the preferred embodiment of the invention has been shown and described, simply by way of illustration of the best mode of carrying out the invention. As will be realized by one of ordinary skill in the art, the invention is capable of modification in various obvious respects, all without departing from the invention. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not restrictive.
FIG. 1 describes a PDP according to the embodiment of the present invention, wherein the PDP comprises a plasma panel 100, an address driver 200, a scan/sustain driver 300, and a controller 400.
The plasma panel 100 comprises a plurality of address electrodes A1 to Am arranged in columns, and a plurality of scan electrodes Y1 to Yn and sustain electrodes X1 to Xn alternately arranged in rows. The controller 400 receives an external image signal (i.e., video signal), generates an address drive control signal and a sustain discharge control signal, and applies them to the address driver 200 and the scan/sustain driver 300, respectively.
