Abstract

An apparatus for driving a PDP is capable of controlling a scan reference voltage when set up pulses are supplied to scan electrodes Yto Ym in a set up period of a reset period and when the scan reference voltage is supplied to the scan electrodes in an address period to reduce the generation of noise. The apparatus for driving the PDP comprises scan electrodes, a scan reference voltage supply comprising a resistance for applying a scan rising waveform that rises to a scan reference voltage with a second slope to the scan electrodes after a rising ramp waveform and a falling ramp waveform having a first slope have been applied to the scan electrodes, and a negative scan voltage supply for applying a negative scan pulse that falls from the scan reference voltage applied by the scan reference voltage supply to the scan electrodes.
