Abstract
A plasma display device that can utilize an energy recovery voltage regardless of whether pixels are selected. An energy recovery circuit of the plasma display device includes first and second switches serially coupled between a first voltage source and a second voltage source, a third switch coupled to a connection point between the first and second switches, a voltage recovery capacitor coupled between the third switch and a base voltage source, and a precharger for charging the voltage recovery capacitor.
