Abstract:
A driving apparatus of a plasma display panel comprising column electrode driving means for applying a pixel data pulse corresponding to pixel data to a plurality of column electrodes arranged in the vertical direction of the plasma display panel and row electrode driving means for applying a first pulse of a predetermined polarity and a second pulse of a polarity different from said predetermined polarity to a plurality of row electrodes arranged in the horizontal direction which cross said column electrodes, respectively, whereinsaid row electrode driving means comprises:a first pulse generating circuit for generating said first pulse and supplying said first pulse to a first line;a second pulse generating circuit for generating said second pulse and supplying said second pulse to said row electrodes; anda switching device which is turned on for at least a period of time when said first pulse generating circuit generates said first pulse, thereby connecting said first line and said row electrodes,wherein said switching device is turned off for a period of time when said second pulse generating circuit generates said second pulse, thereby disconnecting said first line and said row electrodes.
