Patent ID: 6882327

Claim:
An AC type plasma display panel (PDP) drive method, in which a plurality of X electrodes and a plurality of Y electrodes are alternately disposed in parallel to each other on one of two insulating substrates opposed to each other, a plurality of data electrodes are disposed on the other insulating substrate so as to be orthogonal to the X electrodes and Y electrodes, a gap between one X electrode and a Y electrode adjacent to one side of the X electrode is formed as a discharge gap, and a gap between the X electrode and a Y electrode adjacent to the other side of the X electrode is formed as a non-discharge gap, pixels arranged in a matrix form are formed at intersections between the discharge gaps and data electrodes, and every several X electrodes and every several Y electrodes are made to share a driver each, said method comprising a step of writing to the pixels to form wall charges based on display data, the same amount of wall charge being written to the X electrode and Y electrode in one pixel, and lighting and non-lighting of the pixels being controlled in accordance with the wall charge amount, the X electrode and Y electrode being equalized in potential when a writing discharge occurs.
