Patent ID: 7518573

Claim:
A driving method of a plasma display panel comprising: a plurality of first, second, and third electrodes which are disposed to be adjacent to each other and extending in a first direction, said third electrodes being provided respectively between said first and second electrodes between which discharges are to be repeated; and a dielectric layer which covers said plurality of first, second, and third electrodes, wherein grayscale display is carried out by means of a sub-field method, and said third electrodes are set to have a potential which is approximately the same as the potential of one of said first and second electrodes at least at the time of the discharges during a period when the discharges are repeated between said first and second electrodes, and a ratio of the discharges in which said third electrodes operate as cathodes to the discharges in which said third electrodes operate as anodes in the period when said discharges are repeated between said first and second electrodes is changed at least in one sub-field.
