摘要： A plasma display panel driving method and apparatus. In a falling period of a reset period, a voltage at a scan electrode is gradually reduced to the voltage Vnf from the voltage Vs while a sustain electrode is maintained at the voltage Va. In an address period, the voltage Va is applied to an address electrode of a discharge cell to be turned on while the sustain electrode is maintained at the voltage Va. Therefore, the number of voltage sources can be reduced by establishing the voltage applied to the sustain electrode to correspond to the voltage Va in the falling period of the reset period and in the address period.

摘要： Positive and negative sustain discharge voltages of equal magnitude are alternately applied to a scan electrode while biasing the sustain electrode at 0 V during a sustain interval. The positive sustain discharge voltage is applied through the first end of the scan electrode, and the negative sustain discharge voltage is applied through the second end of the scan electrode. The present invention may remove a brightness variation which may occur toward a direction the scanning electrode extends.
