Patent ID: 7176851

Claim:
A panel display apparatus comprising: a gas discharge panel in which a plurality of pairs of first and second electrodes covered with a dielectric are arranged between a pair of substrates; and a driving circuit which accumulates a wall charge on the dielectric to write an image, and successively applies a plurality of sustain pulses to the first electrode and the second electrode to perform a sustain discharge in areas where the wall charge has been accumulated, wherein said driving circuit applies pulses to the first electrode and the second electrode to cause a potential difference between the first electrode and the second electrode generated, wherein said potential difference includes a short pulse being immediately before a leading edge of each sustain pulse and having a predetermined period that is no more than 100 ns, wherein a polarity of the short pulse is opposite to a polarity of the adjacently followed sustain pulse of said potential difference generated between the first electrode and the second electrode and an absolute value of a voltage of the short pulse is no smaller than an absolute value of a voltage of the sustain pulse.
