Abstract:
In a driving method for an AC type discharge display device having one pair of discharge electrodes opposite to each other through a discharge gas filled space and each of said discharge electrodes having a plurality of line-shaped electrodes, at least one discharge electrode of the pair of discharge electrodes being covered with a dielectric layer, said driving method comprising the steps of: a) applying an AC discharge sustaining pulse across the pair of discharge electrodes said AC discharge sustainig pulse having first and second pulses, a predetermined first period between said first and second pulses and a predetermined second period between the end of said second pulse and the beginning of said first pulse of the next AC discharge sustaining pulse, said first pulse being a narrow-width pulse having a pulse width set within a time in which a priming effect of charged particles and metastable atoms generated by said first pulse is kept in the discharge space and said second pulse being a wide width pulse having a width wider than the width of the first pulse and sufficient for giving time until a discharging is stopped by forming wall charges on the dielectric layer and having a polarity reverse to the polarity of said first pulse and generated next to said first pulse; and b) applying said AC discharge sustaining pulse continuously across the pair of discharge electrodes to perform a sustained discharging.
