Patent ID: 7270585

Claim:
A method of aging a plasma display panel having a scan electrode covered with a dielectric layer, a sustain electrode covered with the dielectric layer and a data electrode, said method comprising: during manufacture of the plasma display panel, performing an aging discharge by applying a voltage having an alternating voltage component at least between the scan electrode and the sustain electrode such that the voltage is applied in an alternating manner between one condition in which the scan electrode acts as an anode and the sustain electrode acts as a cathode, and another condition in which the scan electrode acts as a cathode and the sustain electrode acts as an anode; wherein a waveform of voltage applied between the scan electrode and the sustain electrode, in the condition in which the scan electrode acts as the cathode and the sustain electrode acts as the anode, has a gradually ascending leading edge and a sharply descending trailing edge; and wherein a waveform of voltage applied between the scan electrode and the sustain electrode, in the condition in which the scan electrode acts as the anode and the sustain electrode acts as the cathode, has a sharply ascending leading edge and a gradually descending trailing edge.
