Embodiment Construction

[0032] The manufacturing method of the glass rear cover of the present invention will be further described in detail in conjunction with the attached schematic diagram.

[0033] The present invention adopts the following technical scheme: by using the material 2 mask to etch a groove 10 with a uniform depth and a flat bottom on the flat glass to complete the manufacture of the back cover of the device packaging glass. The process for making the glass back cover by etching grooves on flat glass comprises the following steps:

[0034] A. Cut out the glass plate of the required size for cleaning;

[0035] The size is selected according to the needs. You can choose a single glass plate that only needs to be etched locally, such as a single glass back cover, or you can select multiple pieces, such as forming a whole piece of glass plate, which is divided into multiple Glass back cover; after cleaning, it is dried to facilitate bonding with the mask;

[0036] B. Paste the mask mat...

Abstract

This invention relates to a mask used in glass etching and its application in glass etching, in which, the mask includes at least two layers of structures, one is mask material, the other is a glue layer, the mask material is placed above the glue layer and contacted with an etched glass via the glue layer, the mask can be bond on the etched glass stably and not easy to be corroded by acid, and the mask is fixed in the etching of glasses. It is not easy to fall off, it can prevent from acid liquid erosion. It's cost is low, efficiency is high. It can be randomly etched according to the etched pattern, and the groove can be manufactured with high accuracy.

Description

technical field [0001] The invention relates to a mask material and its application in the glass etching process, especially in etching and manufacturing the glass back cover of an organic electroluminescent display device. Background technique [0002] With the development of multimedia technology and the improvement of people's quality of life, in display technology, the performance requirements of flat panel displays are getting higher and higher. As a new type of flat-panel display, organic electroluminescent display has a series of advantages such as self-luminescence, low-voltage DC drive, full curing, wide viewing angle, fast response speed, and rich colors, and is recognized as the main force of the next-generation display. Army, its luminescent principle is to deposit a very thin organic light-emitting material between two electrodes, and make it emit light by applying direct current to the organic light-emitting material. [0003] However, since the organic lumine...
