Problems solved by technology

Therefore, if the accumulation degree of the wall charge is accumulated on the GAP side, the discharge voltage will drop.
[0019] In addition, when the temperature rises, the accumulation degree of charge on the side wall of the GAP is reduced, and at the same time, the sustain voltage Vs applied to the scan electrode Y and the sustain electrode Z will increase during the sustain discharge.

Abstract

The invention is concerned with the plasma display that can maintain the discharge stably, includes: the top base panel forming the scanning electrode and the maintaining electrode on it abreast; the below base panel forming the addressing electrode on it that crosses with the scanning electrode and the maintaining electrode. The addressing electrode includes: the addressing main electrode that is vertical with the scanning electrode and the maintaining electrode and inphase discharge with the scanning electrode; the addressing auxiliary electrode that extends certain extent form both side of the addressing main electrode in the area between the scanning electrode and the maintaining electrode according to the vertical direction of the addressing electrode. The invention can prevent the mis-discharge because of the instable wall electric-charge by self-removing discharge between the scanning electrode and the maintaining electrode, in order to maintain the stable discharge.

Description

technical field [0001] The present invention relates to a plasma display, and more particularly, to a plasma display capable of maintaining a stable discharge. Background technique [0002] When a plasma display (Plasma Display Panel: hereinafter referred to as "PDP") discharges an inert gas mixture such as He+Xe, Ne+Xe, He+Xe+Ne, etc., the ultraviolet light generated emits light from the phosphor to display images. This kind of PDP not only makes ultra-thin and upsizing possible, but also improves the picture quality of the product. [0003] Referring to FIGS. 1 and 2 , the discharge cell of the three-electrode AC surface discharge PDP is equipped with scan electrodes 30Y and sustain electrodes 30Z formed on the upper substrate 10 , and address electrodes 20X formed on the lower substrate 18 . [0004] The scan electrodes 30Y and the sustain electrodes 30Z include: transparent electrodes 12Y, 12Z, which are smaller in line width than the transparent electrodes 12Y, 12Z, an...
