Abstract
The present invention relates to a plasma display panel of the surface discharge type and the AC type. In the plasma display panel of the present invention, scanning pulses are successively applied to a large number of scanning electrodes while data pulses are successively applied to a large number of data electrodes to write wall charge which corresponds to an image into pixels. Then, sustain pulses whose feeding directions are reversed between a first condition and a second condition which occur alternately are fed between the scanning electrodes and sustain electrodes so that discharge occurs at the positions of the pixels in which the wall charge is written to cause a phosphor to emit light to display the image. Since, when the surface discharge electrodes of a predetermined number of one or more rows arranged successively in the column direction are defined as a set, the feeding directions and the positive and negative polarities of the sustain pulses are made opposite between the surface discharge electrodes of odd-numbered sets and even-numbered sets, magnetic noises and electric field noises generated by feeding of the sustain pulses of a high voltage cancel each other, and consequently, such noises can be reduced.
