KR950007613A - Driving Method of Plasma Display Panel - Google Patents

Abstract

The present invention discloses a method of driving a plasma display panel. The method is a method of driving a plasma display panel having a positive electrode driving circuit, a negative electrode driving circuit, and a sustain pulse generating circuit, wherein a scan of a data signal of a positive first voltage applied to a positive electrode and a negative second voltage applied to a negative electrode is performed. A discharge start step of initiating a discharge by a voltage equal to or greater than the discharge start voltage difference of the signal; a discharge pulse initiated by the discharge start step and a sustain pulse having a negative third voltage applied to the sustain electrode periodically; The voltage difference with the other electrodes by maintaining the discharge with the voltage difference from the signal of the four voltages being equal to or higher than the discharge sustain voltage, and by maintaining the sustain pulse having the negative third voltage at the sustain electrode as the fifth voltage. And a discharge erasing step of erasing the discharge by causing the difference to be less than or equal to the discharge sustain voltage. The scan pulses applied to the cathode are sequentially applied, and the sustain pulses applied to the sustain electrodes are sequentially applied to sequentially drive the pulses. Therefore, the configuration of the driving circuit is simplified because the cathode driving circuit only needs to generate two levels of signals.
