ABSTRACT:
A plasma display panel apparatus and a method of driving the same are disclosed. Right after power is supplied to a panel, driving waveforms are applied such that an address discharge and a sustain discharge cannot occur during at least one or more sub-fields. Accordingly, time for a source capacitor of an energy recovery unit provided in a scan driver and a sustain driver to be charged with a voltage can be secured and a preliminary time for an element of the driving circuit and the discharge cell to be activated can be secured, to thereby prevent damage of the element.
