Problems solved by technology

Using this process method, on the one hand, the precision of the groove pattern produced is low, especially the alignment mark, which often cannot meet the requirements of high-precision alignment and bonding with the flat glass front cover during packaging; on the other hand, the protective layer The adhesion to the glass is not good, it is easy to fall off, and it is required to coat on both sides of the glass, and the protective layer on both sides must be removed after etching the groove, so the production efficiency is low and the cost is high, and it is easy to deform for thin glass question

Embodiment Construction

[0021] Below in conjunction with the best embodiment shown in the accompanying drawings, it will be further described in detail.

[0022] like image 3 As shown, the glass back cover 2 of the organic electroluminescent display is a groove 21 etched on the flat glass with a flat bottom and can accommodate the desiccant 5, and the positive and negative electrodes 3 and 4 of the organic electroluminescent display are packaged and sandwiched between the two electrodes. The organic luminescent material layer 6 between them. The process of etching grooves on flat glass to form the glass back cover of the present invention, that is, the method for making the glass back cover of an organic electroluminescent display comprises the following steps:

[0023] A, select the flat glass plate 10 of appropriate size and clean;

[0024] B, plate a very thin transition layer 11 on the front of the cleaned flat glass plate 10, and the transition layer (11) can be a metal layer or a metal oxide...

Abstract

The processing method includes following steps: at first to clean glass plate and plate thin transitional layer and paint photonasty anti-corrosion pretecting layer at the obverse side, to remove the transitional and pretecting layers in pattern to make corrosion pattern by photoetching, to fit two glass plates with etched flute pattern together back to back and seal the around edge, then to etch it till required deep by etching solution, to remove the protecting layer and transitional layer at surface of the glass plates and separate the two glass plates, the glass rear lid of organic electroluminescence display is produced.

Description

technical field [0001] The invention relates to an organic electroluminescence display, in particular to a method for manufacturing the glass back cover thereof. Background technique [0002] Organic electroluminescent display is a new type of flat-panel display at present, because it has many advantages such as active light emission, high contrast ratio, thinness, and fast response speed, it is recognized as the main force of the next generation display, and its light emission principle is in A very thin organic light-emitting material is deposited between the two electrodes, and a direct current is applied to the organic light-emitting material to make it emit light. In organic electroluminescent displays, since organic light-emitting materials are prone to failure when exposed to water and oxygen, the front glass substrate must be packaged with a back cover to isolate moisture and oxygen and prolong the service life of the display. At present, metal back cover, glass bac...
