Patent ID: 7218292

Claim:
A method of driving a plasma display panel comprised of (A) a first substrate including at least one first electrode, and at least one second electrode extending in parallel with said first electrode and defining a display area with said first electrode therebetween, and (B) a second substrate including at least one third electrode facing said first and second electrodes and extending perpendicularly to said first and second electrodes, wherein a display cell is arranged at each of intersections of said first and second electrodes with said third electrode, said method including: (a) applying a serrate voltage having an inclined waveform in which a voltage varies with the lapse of time, to at least one of said first and second electrodes; and (b) applying a preliminary charge-eliminating pulse voltage to at least one of said first and second electrodes after said a charge-eliminating discharge has been generated due to said serrate voltage, wherein said preliminary charge-eliminating pulse voltage eliminates electric charges only when electric charges have not been sufficiently eliminated.
