Abstract:
A method of driving a plasma display panel in which a plurality of sustain electrodes X.sub.i and a plurality of scan electrodes Y.sub.n are arranged adjacent to each other on a first substrate in corresponding to display lines, and a plurality of address electrodes A.sub.j electrically isolated from said sustain electrodes X.sub.i and said scan electrodes Y.sub.n are arranged on a second substrate opposing said first substrate, in such a manner as to intersect with said sustain electrodes X.sub.i and said scan electrodes Y.sub.n, forming a discharge cell in each intersection comprising:in an odd field, producing a display between odd-numbered sustain electrodes X.sub.2i-1 and scan electrodes Y.sub.2n-1 and between even-numbered sustain electrodes X.sub.2i and scan electrodes Y.sub.2n and, in an even field, producing a display between the odd-numbered sustain electrodes X.sub.2i-1 and the even-numbered scan electrodes Y.sub.2n and between the even-numbered sustain electrodes X.sub.2i and the odd-numbered scan electrodes Y.sub.2n-1, each of said odd and even fields including a reset period, an address period and a sustain discharge period, the method further comprising:in each reset period, carrying out a reset discharge in a plurality of said discharge cells to accomplish a uniform charge distribution among said plurality of discharge cells,a reset period, carrying out a write discharge in selected discharge cells between said scan electrodes Y.sub.n and said address electrodes A.sub.j, thereby selectively writing display data, andin each sustain discharge period, applying sustain discharge pulses between said sustain electrodes X.sub.i and said scan electrodes Y.sub.n, thereby causing a glow discharge for producing said display at said discharge cells in which the writing has been performed in said address period; amdholding respective potential differences between said odd-numbered sustain electrodes X.sub.2i-1 and said even-numbered scan electrodes Y.sub.2n and between said even-numbered sustain electrodes X.sub.2i and said odd-numbered scan electrodes Y.sub.2n-1 during the reset period of said odd field, and respective potential differences between said odd-numbered sustain electrodes X.sub.2i-1 and scan electrodes Y.sub.2n-1 and between said even-numbered sustain electrodes X.sub.2i and scan electrodes Y.sub.2n during the reset period of said even field, below a level of a discharge initiating voltage between the respective electrodes.
