Abstract:
A plasma display comprising:a matrix electrode section including a plurality of scan electrodes, a plurality of sustain electrodes arranged parallel to said scan electrodes, and a plurality of data electrodes crossing said scan and sustain electrodes at right angles; a plurality of display cells formed at the intersections of said scan electrodes, said sustain electrodes, and said data electrodes; and a plurality of driving means connected to said scan electrodes, said sustain electrodes, said data electrodes to drive said display cells, each of said driving means including first and second switching means for alternately applying first and second sustain pulses respectively having positive and negative potentials with respect to a reference potential of said data electrode to said scan and sustain electrodes such that a potential relationship between said scan and sustain electrodes is periodically reversed, third switching means for applying a scan pulse having a negative potential higher than the potential of the second sustain pulse to said scan electrode to superimpose the scan pulse on the second sustain pulse, fourth switching means for applying a semi-selection pulse having a potential lower than the potential of the first sustain pulse to said sustain electrode corresponding to said scan electrode when a scan pulse is applied to said scan electrode, and fifth switching means for selectively applying a data pulse having a positive potential with respect to the reference potential of said data electrode to said data electrode in accordance with a timing at which a scan pulse is applied to said scan electrode.
