PLASMA DISPLAY APPARATUS AND DRIVING METHOD THERE OF

摘要

A plasma display device and a driving method thereof are provided to generate an effective discharge by preventing a peaking current as a voltage is abruptly changed. A plasma display panel(100) has scan electrodes, and a scan driver(123) supplies a setup pulse to the scan electrodes during a reset period of a subfield. The setup pulse gradually rises to a first voltage level with a first slope at a reference voltage, rises from the first voltage level to a second voltage level with a second slope smaller than the first slope, and rises from the second voltage level to a third voltage level with a third slope different from the second slope. The scan driver has a sustain voltage supply unit supplying a sustain voltage to the scan electrodes, a setup voltage supply unit supplying first and second setup voltage to the scan electrode, and a slope controller controlling the first to third slopes.
