ABSTRACT:
A scan electrode driving apparatus of an AC PDP including a plurality of address electrodes and a plurality of scan electrodes and sustain electrodes alternately arranged to make pairs with each other, and having a panel capacitor between the scan electrodes and the sustain electrodes, includes a power recovery unit for supplying power to a panel in order to apply waveforms for sustain-discharge and recovering and re-using the supplied power, a ramp waveform applier for supplying a pulse signal for resetting the states of the respective discharge cells on the basis of the power received from the power recovery unit, and a scan pulse generator for accumulating a wall charge into the addressed discharge cells.
