Abstract:
A method of driving a plasma display device having a plasma display panel includinga plurality of pairs of first and second discharge-sustaining electrodes, a plurality of address electrodes arranged to intersect said plurality of pairs of first and second discharge-sustaining electrodes, a dielectric substance covering said plurality of pairs of first and second discharge-sustaining electrodes, and a plurality of discharge cells defined by said plurality of pairs of first and second discharge-sustaining electrodes and said plurality of address electrodes; said method including at least address-discharge period for addressing said plurality of discharge cells and thereby inducing address-discharge therein; and light-emission period for applying repetitive discharge-sustaining pulse voltages to at least one of said first and second discharge-sustaining electrodes such that said addressed ones of said plurality of discharge cells start and sustain main discharge depending upon the presence of said address-discharge to generate light for formation of a display wherein second repetitive pulse voltages are applied to said plurality of address electrodes to generate pre-discharge, said pre-discharge initially occurring between said address electrodes of said addressed ones of said plurality of discharge cells and one of said first and second discharge-sustaining electrodes of said addressed ones, and thereafter occurring between said first and second discharge-sustaining electrodes of said addressed ones, and said second repetitive pulse voltages rise in portions of said light-emission period during which an absolute value of a voltage difference between said pair of first and second discharge-sustaining electrodes does not exceed 0.9Ã—a maximum of an absolute value of a voltage difference between said pair of first and second discharge-sustaining electrodes during said light-emission period.
