Driving method for plasma display panel

Abstract

A plasma display device has a display panel including first and second electrodes arranged in parallel with one another and third electrodes arranged to be orthogonal to the first and second electrodes. A slit coincident with a line formed by discharge cells is selected by applying a scanning pulse and addressing signal at an addressing step (A) and sustaining discharge (S) is initiated in the selected slit at a sustaining discharge step. In a drive method for the plasma display device, first and second slits are defined between a second electrode and first electrodes on one side and the other side of the second electrode. Interlacing is carried out by displaying lines coincident with the first slit and second slit alternately. A charge adjustment step (T) is set between the addressing step and sustaining discharge step. At the charge adjustment step, a charge adjustment pulse is applied in order to adjust at least one of the polarity and magnitude of a wall charge accumulated due to discharge occurring at the addressing step. Such a drive method can ensure normal display on a stable basis for a plasma display panel in which sustaining discharge pulses that are mutually out of phase are applied to adjoining slits in order to initiate sustaining discharge, and to thus specify display slits between a Y electrode and X electrodes across the Y electrode.
