Embodiment approach

[0025] According to a typical embodiment of the present invention, the manufacturing method of the PDP discharge electrode includes the following steps: forming a first transparent electrode 11 and a second transparent electrode 21; forming a first transparent electrode 11 and a second transparent electrode 21 on the first transparent electrode 11 and the second transparent electrode 21 respectively. The bus electrode 12 and the second bus electrode 22; the first three-dimensional portion 12a and the second three-dimensional portion 22a are respectively formed on the first bus electrode 12 and the second bus electrode 22 by printing method, developing method or etching method. Wherein, the transparent electrodes and bus electrodes can be produced by conventional production methods in the art, such as printing method, developing method or etching method.

[0026] When the first three-dimensional part 12a and the second three-dimensional part 22a are produced by a printing method...

Abstract

A plasma display panel (PDP) discharge electrode and a method of manufacturing same. The PDP discharge electrode comprises: a first transparent electrode (11) and a first bus electrode (12) provided thereon; and a second transparent electrode (21) and a second bus electrode (22) provided thereon. The first transparent electrode (11) is provided opposite the second transparent electrode (21), and a discharge space (30) is formed therebetween. The first bus electrode (12) is provided with a first solid portion (12a) that extends into the discharge space (30), and the second bus electrode (22) is provided with a second solid portion (22a) that extends into the discharge space (30). Because the bus electrode of the PDP discharge electrode is provided with solid portions that extend into the discharge space, the discharge occurs in the space, increasing the discharge electrode surface area and increasing the amount of electrons produced by the discharge. During discharge, an ignition occurs in the space, increasing the ignition area. In this way, the brightness of the PDP is improved.

Description

technical field [0001] The invention relates to the field of gas discharge, in particular to a PDP (Plasma Display Panel) discharge electrode and a manufacturing method. Background technique [0002] At present, the general AC gas discharge plasma display screen adopts a surface discharge type structure, and the surface discharge type structure includes a front substrate and a rear substrate sealed together with it. A transparent electrode ITO (Indium Tin Oxide) and a bus electrode are arranged on the front substrate, and the transparent electrode and the bus electrode constitute a discharge electrode. The discharge electrode includes a sustain discharge electrode X and a scan discharge electrode Y. The surface of the discharge electrode is covered with a dielectric layer, and the dielectric layer is covered with a protective layer, and the protective layer is a magnesium oxide film. The rear substrate is provided with address electrodes that are perpendicular to the discha...
