Problems solved by technology

[0009]Another object of the present invention is to provide a method for digital etching of glass, which uses a mask on the back of the glass to expose the etched part, and then Through digital etching, the groove depth of the glass back cover made of organic electroluminescent display devices can be precisely controlled, which solves the problem that the depth of the glass back cover groove cannot be accurately controlled in the simulated corrosion measured by time

Embodiment Construction

[0033] Below, with reference to the accompanying drawings, a further detailed description will be made on the glass rear cover of the organic electroluminescence display device manufactured by the present invention.

[0034] figure 1 As shown, the mask material used in the present invention generally includes a mask material 2, an adhesive surface 3 and a protective film 4, and the mask material 2 is a basic covering material for covering a glass plate surface that does not need to be etched; The adhesive surface 3 is used to tightly combine the mask material 2 and the glass plate 1, and there is no gap between the two; the protective film 4 is used to protect the adhesive surface 3 from being damaged when not in use. If it is damaged, when using the mask material 2, remove the protective film 4, align the adhesive surface 3 with the glass plate 1 to cover, and press the mask material 2 so that it is tightly covered on the glass plate 1, and the adhesive surface 3 The two ar...

Abstract

This invention relates to a digitalized etching method for glasses including: cleaning glass plates and masking to determine necessary etched patterns and erode and dip them in a deglue solution, then strips the masked material on it to get a necessary glass, which applies mask on glasses to expose the being etched part then to digital-etch it so as to accurately control the groove depth of the etched glass and solve the problem that it's hard to control the groove depth of glasses in the traditional erosion measured by time.

Description

technical field [0001] The invention relates to a glass etching method, in particular to an etching method capable of accurately controlling the glass etching depth, and in particular to a digital etching method for manufacturing a glass back cover of an organic electroluminescence display device. Background technique [0002] As an emerging flat-panel display, organic electroluminescent devices are recognized as the main force of next-generation displays due to their advantages such as self-luminescence, low-voltage DC drive, full curing, wide viewing angle, fast response speed, and rich colors. military. However, since organic light-emitting materials are prone to failure when exposed to water and oxygen, they must be packaged with a back cover to isolate water vapor and oxygen, and be packaged with a desiccant to prolong the service life of the display. [0003] At present, metal back cover, glass back cover or thin film are mainly used for encapsulation. Among them, t...
