US 6,472,826 B2 · Method of driving plasma display panel and a plasma display device using the method

Abstract

A method of driving a plasma display panel, where the plasma display panel has opposing front and rear substrates which are spaced facing each other, X and Y electrode lines which are formed in parallel between the front and rear substrates, and address electrode lines formed to be perpendicular to the X and Y electrode lines so that discharge cells are defined by the crossing X and Y electrode lines and the address electrode lines. The method includes periodically applying display pulses to all the X and Y electrode lines, initializing the discharge conditions of a previous sub-field, and forming wall charges at discharge cells to be displayed in a current sub-field are sequentially performed while the display pulses are not applied. A bias pulse having the same polarity as and a lower voltage than the display pulses is applied to all the address electrode lines while the display pulses are applied.
