ABSTRACT:
A method for driving an AC-driven plasma display panel (PDP) having a three-electrode surface discharge structure constructed to have a first electrode and a second electrode both extending in a direction of a row line of elements arranged in matrix and a third electrode extending in a direction of a column line of the elements, the method including the step of applying, upon displaying images in time sequence, erase voltage pulses of different polarities for erasure to the second electrode and the third electrode so that an effective voltage exceeds an opposition discharge start voltage only in the case where a wall voltage of a predetermined value or higher is superposed on the voltage pulses, during a period from the end of sustaining the light-emission discharge for display for an image to the beginning of addressing for a next image.
