Abstract

A driving apparatus of a plasma display panel which can apply a plurality of driving pulses of different polarities onto same row electrodes of the PDP by a transistor of a low withstanding voltage. The apparatus has a first pulse generating circuit for generating a first pulse of a predetermined polarity and applying it to a first line and a second pulse generating circuit for generating a second pulse of a polarity different from the predetermined polarity and applying it to the row electrodes of the plasma display panel. A switching device which is turned on for at least a period of time when the first pulse generating circuit generates the first pulse and connects the first line and the row electrodes is provided between the first and second pulse generating circuits.

Dependent claims

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, wherein

said 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;
and
a 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.
