DRIVING METHOD OF AC DISCHARGE MEMORY OPERATING TYPE PLASMA DISPLAY PANEL

PROBLEM TO BE SOLVED: To stably eliminate electric charge on a data electrode, and perform reliable driving control by impressing a driving pulse so that counter discharge and surface discharge in eliminating discharge of a maintaining eliminating period separate from each other in time. SOLUTION: In a maintaining eliminating period, a maintaining eliminating pulse Psena set in positive polarity to a data electrode is impressed on the whole scanning electrodes. A bias pulse Peb in the same polarity as the maintaining eliminating pulse Psena is impressed on a maintaining electrode. Just before entering the maintaining eliminating period, wall electric charge generated by the final maintaining pulse of a maintaining discharge period is held at time of the timing D, but this wall electric charge is superimposed on voltage of the maintaining eliminating pulse Psena, and while, since the bias pulse Peb is polarity for negating the wall electric charge, effective voltage of a discharge gas space exceeds discharge starting voltage only between the scanning electrodes and the data electrode, so that eliminating discharge between counter electrodes is generated. Afterwards, when the bias pulse Peb drops off, the effective voltage between the scanning electrodes and the maintaining electrode also exceeds the discharge starting voltage, so that eliminating discharge between surface electrodes is generated.
