Abstract:
1. A method for driving a plasma display panel including a scan electrode and a sustain electrode provided in parallel on a first substrate, and an address electrode provided on a second substrate, the address electrode crossing the scan electrode and the sustain electrode, the method comprising: during a reset period, applying a ramp voltage to the sustain electrode to a first voltage after a previous sustain period is complete; maintaining the address electrode and the sustain electrode at a second voltage, and applying a rising ramp voltage to the scan electrode, the rising ramp voltage gradually rising from a third voltage to a fourth voltage, the third voltage being less than a discharge firing voltage with respect to the sustain electrode and the fourth voltage being greater than the discharge firing voltage; applying a falling ramp voltage to the scan electrode while maintaining the sustain electrode at a first bias voltage, the falling ramp voltage gradually falling to a predetermined voltage from the third voltage; and maintaining the sustain electrode at a second bias voltage below the first bias voltage while maintaining the scan electrode at the predetermined voltage after the applying a falling ramp voltage.
