ABSTRACT:
A circuit for driving a plasma display panel includes a scan pulse drive integrated circuit having a plurality of output terminals, and a diode array composed of a corresponding number of diodes each having a cathode connected to a corresponding one of the plurality of output terminals. Anodes of all the diodes are connected in common to one end of a first switch having the other end connected to ground. A high voltage side power supply terminal of the scan pulse driving circuit is connected through a second switch to a negative power supply. During a hold period, the first switch is turned on, but the second switch is turned off, so that a discharge current flows through the diode array to display cells of the plasma display panel, without passing through the inside of the scan pulse driving circuit.
