Abstract
A display panel has a plurality of first electrodes, a plurality of second electrodes adjacently disposed alternately with the first electrodes, a plurality of third electrodes formed to cross the first and second electrodes, and a control circuit for having an address discharge carried out during the second electrodes and the third electrodes. The control circuit has a sustain discharge carried out to decrease the volume of wall charges, accumulated on a display cell in which a sustain discharge is not intended, to a level which cannot generate a sustain discharge.

A method of driving a plasma display panel having a plurality of first electrodes, a plurality of second electrodes adjacently disposed alternately, and a plurality of third electrodes formed to cross said first and second electrodes, comprising the steps of:
- carrying out an address discharge between said second electrodes and said third electrodes;
- carrying out an auxiliary discharge to decrease the volume of wall charges, accumulated on a display cell in which a sustain discharge is not intended, to a level which cannot generate a sustain discharge;
- and
- carrying out a sustain discharge by alternately applying sustain pulses to said first and second electrodes.
A method of driving a plasma display panel having a plurality of first electrodes, a plurality of second electrodes adjacently disposed alternately, and a plurality of third electrodes formed to cross said first and second electrodes, comprising the steps of:
- carrying out an address discharge between said second electrodes and said third electrodes;
- carrying out a sustain discharge by alternately applying sustain pulses to said first and second electrodes;
- and
- carrying out an auxiliary discharge of a scale larger than the scale of the sustain discharge carried out immediately before.
A method of driving a plasma display panel having a plurality of first electrodes, a plurality of second electrodes adjacently disposed alternately, and a plurality of third electrodes formed to cross said first and second electrodes, for applying at a reset timing an erasing pulse having a dull inclination with respect to said second electrodes to which a scan pulse is applied, comprising the step of:
- steeply changing a pulse voltage until when the pulse voltage becomes equivalent to a voltage of the scan pulse, at an end stage of the erasing pulse.
