Abstract
Provided are an energy recovery apparatus and method for recovering energy in a plasma display panel (PDP) at improved efficiency using a single energy storage device and a small number of devices regardless of the number of pixels that become conductive as a result of the screen state. The energy recovery apparatus includes a first closed circuit, which supplies predetermined source voltage to pixels for conduction according to a predetermined switching sequence; a second closed circuit, which uses a single energy storage device to recover energy discharged from the pixels that have been charged by the first closed circuit; and a third closed circuit, which transfers the energy stored in the energy storage device to pixels for conduction according to the predetermined switching sequence.
