Abstract
A PDP energy recovery apparatus and method controls the time point of charging and discharging energy to a plasma display panel (PDP) optimally and performs a high speed addressing. The PDP energy recovery apparatus includes a PDP, a driving integrated circuit unit for driving the PDP; and a PDP energy recovery circuit units for supplying energy to the PDP, charging an electric charge in the PDP at the time point when the electric charge discharged from the PDP is outputted the smallest, discharging the electric charge charged in the PDP, to thereby quicken the operating speed of the PDP.
