Method for making glass rear cover of organic electroluminescence display

Abstract

Disclosed is a method for making glass back cover of organic electric-driver flaring display, which includes the following steps: firstly, wash the glass plate (10), then paste a layer of erosion-resisting film (7) on its face ; then cut the figure by laser and clear the film (7) in the figure; stick the two glass plates with figure on their backs and seal their edges, use etching solution to etch, reaching the depth needed; clear away proteting film (7) the glass plate (10), separate and cut the two plates (10), obtaining the glass back cover (2) of organic electric-driven flaring display. The invention has high accuracy and efficiency, low cost, can be applied in glass engraving, etch on viehcle glass and other industries.

Description

technical field [0001] The invention relates to a manufacturing method of an organic electroluminescent display, in particular to a manufacturing method of its glass back cover. 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. [0003] 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, me...

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 fails to meet the requirements of high-precision alignment and bonding with the flat glass front cover during packaging; on the other hand, the protective film 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 film 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

[0005] Another existing production method is to use photolithography to produce high-precision etching patterns. To apply this method, a layer of photosensitive anti-etching protective layer needs to be coated on the glass. The metal protection layer, the photosensitive anti-etching protection layer can be firmly attached to the glass surface and not easy to fall off. In addition, after the pattern is etched, the metal layer needs to be removed with an acid etchant, so the process is more complicated and difficult. relatively high cost
