Abstract:
A drive method for a plasma display panel comprising a plurality of scan electrodes, a plurality of sustain electrodes formed on the same flat surface as said scan electrodes and forming pairs with said scan electrodes, a plurality of data electrodes orthogonal to said scan electrodes and said sustain electrodes, and a plurality of display cells formed at the intersections between said data electrodes with said scan electrodes and said sustain electrodes, wherein one period of said drive is composed of an addressing discharge interval and a sustaining discharge interval, wherein said sustaining discharge interval follows an addressing discharge for determining lighting or non-lighting of each of said display cells, said sustaining discharge interval repeating discharge states based on selected discharge from said addressing discharge; said drive method for said sustaining discharge interval comprising the steps of:(a) making a potential of a leading sustaining discharge pulse negative polarity compared to a data electrode potential, while said plurality of data electrodes and said plurality of scan electrodes are set to a same potential; and(b) making a high-potential side of second and subsequent sustaining discharge pulses positive polarity compared to the data electrode potential and making a low-potential side negative polarity compared to the data electrode potential.
