Plasma display panel without transparent electrode structure and methods for manufacturing upper substrate thereof

Abstract

The invention discloses a plasma display panel without a transparent electrode structure, which comprises an upper substrate and a lower substrate sealed with the upper substrate, wherein the upper substrate is provided with a first magnesium oxide layer positioned on the surface of upper substrate glass, a silver electrode X and a silver electrode Y which are positioned on the surface of the magnesium oxide layer, a dielectric layer positioned on the surfaces of the silver electrode X and the silver electrode Y, and a second magnesium oxide layer positioned on the surface of the dielectric layer. The invention also discloses two methods for manufacturing the plasma display panel without the transparent electrode structure, namely an electron beam evaporation method and a magnetron sputtering method. The manufacturing cost is reduced and the brightness is increased.

Description

technical field [0001] The invention belongs to the field of gas discharge, and in particular relates to a plasma display screen without a transparent electrode structure and a method for manufacturing the upper substrate thereof. Background technique [0002] At present, the general-purpose AC gas discharge plasma display adopts a surface discharge structure, which includes an upper substrate and a lower substrate sealed together with it.

Problems solved by technology

The inventors have found that reducing the transparent electrode will help reduce the overall manufacturing cost. However, the adverse effect of reducing the transparent electrode layer is that if the bus electrode, that is, the silver electrode, is in direct contact with the upper substrate glass, it will cause the glass to turn yellow. , which affects the visual effect

[0008] In addition, when reducing transparent electrodes, how to design corresponding silver electrodes has also become a design difficulty
