Patent ID: 7528801

Claim:
A method for driving a plasma display panel comprising a plurality of discharge cells corresponding to a plurality of first electrodes and a plurality of second electrodes, and a driving circuit comprising a first switch having a first terminal electrically coupled to a power supply for supplying a first scan pulse voltage and a second terminal electrically coupled to the first electrodes, and a series combination of a second switch and at least one Zener diode electrically coupled in parallel with the first switch between the first terminal and the second terminal of the first switch, the plasma display panel configured to be driven during a plurality of subfields, each subfield comprising a reset period, an address period, and a sustain period, the method comprising: in the address period, a) turning on the first switch to apply the first scan pulse voltage to at least two adjacent electrodes among the plurality of first electrodes; and b) turning on the second switch to apply a second scan pulse voltage, which is lower than the first scan pulse voltage, to at least two other adjacent electrodes among the plurality of first electrodes, which are scanned later than the at least two adjacent electrodes.
