3D (three-dimensional) glass cover plate and method for manufacturing same

Abstract

The invention discloses a 3D (three-dimensional) glass cover plate and a method for manufacturing the same. The method includes main steps of coating photoresist on glass; developing target patterns by means of exposure; chemically etching display regions and forming grooves by means of machining; removing the photoresist on the surfaces of the glass by the aid of release agents; carrying out appearance processing and light sweeping, to be more specific, processing the glass by the aid of a numerical-control machine tool to obtain the outer contour of the cover plate and 2.5D (2.5-dimensional) edges of the upper surface of the cover plate and then carrying out light sweeping on the 2.5D edges and the grooves; chemically tempering the glass to obtain the 3D glass cover plate which is a finished product. The target patterns include protected regions and etched regions, the photoresist covers the protected regions and does not cover the etched regions, and the etched regions include the display regions, and touch display modules can be correspondingly laminated on the display regions. The 3D glass cover plate and the method have the advantages that the integral thicknesses of touch screens can be reduced, 2.5D and 3D effects can be realized by the appearance of the edges, and requirements on lightening and thinning the 3D glass cover plate can be met; chemical etching processing technologies are exquisite, and accordingly the strength, the precision, the production efficiency and the high degree of automation of the product can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of glass cover processing, in particular to a 3D glass cover and a manufacturing method thereof. Background technique [0002] The glass cover is also called window protection glass, which is an important component of mobile phones, tablet computers, digital cameras or notebook computers. At present, the glass cover is mostly designed with a touch screen, which is arranged on the liquid crystal screen and is used to accept the user's pressing, so as to realize the control of the touch screen. [0003] With the development of electronic equipment with curved screens, people have higher and higher requirements for the appearance, thinness and comfort of touch screens. The traditional flat glass cover is gradually upgraded to 2.5D, 3D and other special-shaped curved glass covers. . 2.5D glass cover means that the edges of the cover have a smooth transition, and 3D glass cover means that the overall surface is...

AI Technical Summary

Problems solved by technology

[0004] At present, the 2.5D and 3D glass covers on the market are mainly produced by hot pressing or CNC machining and grinding. However, the existing processing methods cannot meet the further thinning, strength, and precision requirements of the glass cover.
