| description | A driving apparatus of a plasma display panel (PDP) operates stably and reliably. The driving apparatus to drive the PDP includes a pulse application unit which applies a pulse to the PDP; and an energy recovery unit which comprises an inductor which generates LC resonance with a panel capacitor element of the PDP, an energy recovery determiner which determines the accumulation of energy during the LC resonance or emission of the accumulated energy to the PDP, and an energy storage unit which stores the accumulated energy, wherein the energy recovery determiner comprises a first falling switching device which determines the accumulation of the energy; and a second falling switching device which is connected between the first falling switching device and the energy storage unit, in order for the second falling switching device to form a current path toward the energy storage unit. A drive unit supplies a switching voltage directly to the first falling switch without the intermediary of a capacitor. The drive unit has an amplifier, a bootstrap capacitor and a bootstrap diode. |
