Problems solved by technology

As a result, during calcination, the partition walls may be distorted and deformed
Therefore, it is difficult to accurately position each electrode at the ideal position of each electrode, that is, the center position between the two partition walls

Abstract

Disclosed is a rear plate of a plasma display panel. In the rear plate, barrier ribs are formed through etching after backing, and thus the completed barrier ribs are not deformed. Therefore, each electrode can be exactly located on a central portion between barrier ribs. When a PDP having front and rear plates attached to each other has been completed, optical characteristics of the PDP such as white brightness, color temperature, and contrast, and electric characteristics of the PDP such as voltage margin, power consumption, and electric efficiency, are improved, so that the reliability is improved.

Description

technical field [0001] The present invention relates to a rear panel for a plasma display panel. Background technique [0002] As generally known in the art, a plasma display panel (PDP) is a display device having a front glass substrate and a rear glass substrate with a discharge space formed therebetween so as to generate a plasma discharge in the discharge space, thereby causing phosphorescence in the discharge space The body is excited to emit light, thus displaying a fluorescent screen. [0003] The plasma display panel can be classified into a direct current plasma display panel (DC PDP) and an alternating current plasma display panel (AC PDP), among which the AC plasma display panel is the mainstream. US Patent No. 5,446,344 discloses a three-pole surface discharge AC plasma display panel, which is one of the representative AC plasma display panels. [0004] The plasma display panel includes a front panel and a rear panel assembled in parallel to each other. The fr...
