Problems solved by technology

[0004] The purpose of the present invention is to solve the problems of large waste of resources, low production efficiency, yellowing of the panel, low picture quality and large loss in the existing method of manufacturing the front plate metal electrode of the plasma display panel. The black paste of metallic silver Ag is formed on the glass substrate in a trapezoidal shape, and then a conductive silver paste is formed on the black paste, which can effectively prevent the silver particles in the conductive silver paste from diffusing downward into the glass substrate to cause yellowing reaction Fabrication method of front plate metal electrode of shadow mask type plasma display panel capable of preventing yellowing of panel

Embodiment 1

[0036] Such as Figure 1-5 shown.

[0037] A method for manufacturing a metal electrode on the front plate of a shadow mask type plasma display panel that can prevent yellowing of the panel. A black paste layer that does not contain silver, and then form a conductive silver paste on the black paste layer to prepare electrodes to prevent the replacement reaction between the silver ions in the conductive silver paste and the Na and K metal ions in the glass substrate to cause yellowing of the panel occurrence of the phenomenon.

[0038] The specific production steps include:

[0039] a. clean the glass substrate 13 (can be the glass substrate that finally forms the front substrate glass substrate 8, also can be the glass substrate that finally forms the rear substrate glass substrate 4), make PVA on the surface of the glass substrate 13, and can be burned The photosensitive layer 14 decomposed in the forming process, the thickness of the photosensitive layer 14 is controlled ...

example 1

[0049] A method for making a front plate metal electrode specifically comprises the following steps:

[0050] 1. Clean the glass substrate 13, and form a photosensitive layer 14 with a thickness of 10-30 μm on the surface of the glass substrate 13.

[0051] 2. Exposure: Adopt the contact exposure method, tile the surface of the photosensitive layer 14 with the mask plate 15 with the electrode pattern, then irradiate the mask plate 15 and the photosensitive layer 14 with ultraviolet light 16, the above-mentioned pattern mask in the exposure process The light diffraction and refraction of the plate 15 form a reverse trapezoid, and the ultraviolet light 16 penetrates the transparent area on the mask plate 15 and irradiates the corresponding position of the photosensitive layer 14, so that this part of the photosensitive material is cured to form a cured photosensitive material 17; The opaque area on the film plate 15 can block the irradiation of the ultraviolet light 16 and keep ...

example 2

[0057] In the above-mentioned example 1, the glass substrate with the electrode pattern is sintered under the firing conditions of 550°C and 15 minutes of heat preservation, which constitutes the second group of embodiments of the present invention.

Abstract

The invention discloses a method for producing a metal electrode of a front panel of a shadow mask plasma display panel capable of preventing the panel from yellowing, which is characterized in that the method synchronously has the characteristics of thick film photolithography and thin film photolithography methods, and prepares the electrode by a method of forming a black slurry layer without silver on a glass substrate (13) first and then forming conductive silver paste on the black slurry layer to prevent a replacement reaction between silver ions in the conductive silver paste and Na and K metal ions in the glass substrate so as to avoid the yellowing phenomenon of the panel. The method utilizes a photosensitive material to form an inverse trapeziform space on the glass substrate through exposure development, fills black slurry and conductive silver paste into the space, and is favorable for reducing the production cost for the shadow mask plasma display panel.
