The plasma display panel with the electrode structure of new discharge AND gate and its driving scheme were proposed and the driving system for experiment was developed. And operation of these discharge AND gate was verified by the experiment of PDP addressing with floating electrode. This discharge AND gate operated by the operation speed of 8$mutextrm{s}$ and the operation margin of 100V. The address operation margin of 10V also obtained. It was known to be able to control the discharge of the adjoining scan electrode accurately. Because proposed method uses the DC discharge the control of the discharge can be facilitated compared with conventional discharge AND gate. Moreover, because the input discharge and the output discharge of discharge gate are separate, the display discharge can be prevented from passing discharge gates. Therefore, it is possible to apply to the large screen plasma display panel. And the decrease of contrast ratio does not occur because the scanning discharge does not influence the picture quality.
