Description

Glass cover plate and manufacturing method thereof

The invention relates to a glass cover plate, in particular to a glass cover plate for an electronic device and a manufacturing method thereof.

Due to the good strength and scratch resistance of glass materials, glass cover sheets are becoming more and more popular as shells in current electronic devices, especially consumer electronic devices. However, the current glass cover is mostly made of transparent glass and has a decorative coating on the inner surface. Therefore, the appearance of the glass cover is not easily differentiated. In addition, the consumer electronic device usually sets the camera and the flash. When the transparent glass cover is used as the outer casing, the camera will framing through the glass cover, and the transparent glass cover easily spreads various stray light to the camera. Affect image quality. Moreover, when the camera is shot with the flash, part of the light from the flash enters the glass cover and propagates to the camera, causing severe glare and affecting image quality.

In view of the above, it is necessary to provide a glare-proof and aesthetically pleasing glass cover to solve the above problems.

In view of the above circumstances, it is also necessary to provide a method of manufacturing a cover glass to solve the above problems.
