Method and apparatus of driving plasma display panel

摘要

The present invention relates to a method and apparatus for driving a plasma display panel in which a margin of an address discharge and a sustain discharge is increased through a stabilized reset operation. According to an embodiment of the present invention, the method of driving the PDP includes the steps of applying a first ramp-down pulse having a first tilt to scan electrodes in the first half of a set-down period included in a reset period, applying a ground voltage to the scan electrodes in the meddle phase of the set-down period, and applying a second ramp-down pulse having a second tilt to the scan electrodes in the second half of the set-down period.
