ABSTRACT:
The present invention relates to a plasma display panel, and more particularly, to an apparatus and a method of driving a plasma display panel. According to an embodiment of the present invention, an apparatus of driving an AC surface discharge type plasma display panel, which includes X-, Y-, and Z-electrodes for discharge initiation and discharge sustain, includes a central arithmetic logical unit, a reset drive unit, a data drive unit, a scan drive unit, and a sustain drive unit and wherein the sustain drive unit includes a unified sustain drive unit. Accordingly, an apparatus for driving a plasma display panel and method thereof according to the present invention includes the unified sustain drive unit, thereby enabling to raise the drive efficiency, to simplify the circuit configuration, and to reduce the circuit volume.
