ABSTRACT:
An apparatus for driving a plasma display panel includes a first driver and a second driver and a first power supplier and a second power supplier for generating sustain discharge pulses having no negative (−) level. The first driver includes a first capacitor charged to a first voltage and is coupled to a power source for supplying a voltage Vsand a ground voltage. The first driver, coupled to one terminal of a panel capacitor, operates to alternately apply double the voltage Vsformed by the power source and the first capacitor and the ground voltage to the one terminal of the panel capacitor. The second power supplier, coupled to the power source and the ground voltage, includes a second capacitor charged to Vs. The second driver coupled to the other terminal of the panel capacitor operates to alternately apply double the voltage Vsformed by the power source and the second capacitor and the ground voltage to the other terminal of the panel capacitor. Here, one of the first driver and the second driver applies the ground voltage to the panel capacitor, while the other applies double the voltage Vsto the panel capacitor.
