Description

Screen protector and electronic device having the same

The invention relates to a screen protector, in particular to a screen protector applied to an arc-side screen and made of glass material and an electronic device having the screen protector.

Regarding portable electronic devices, such as smart mobile phones or tablet computers, screen protectors are usually attached to the screen because they all have a screen and protect the screen from unsightly scratches.

Older electronic devices have a flat screen and do not have a solid arc (2.5D or 3D arc), so you can use the old soft screen to protect the film. Among them, the hardness of these soft screen protection films is between 2.5H-3H.

Nowadays, the arc-side screen with a three-dimensional arc edge (hereinafter referred to as the arc-edge screen) has gradually become the mainstream. Although such a screen has a better grip and aesthetics, the screen is relatively easy to scratch, so the hardness is changed. A hard (glass) screen protector of about 9H, and a protective screen edge corresponding to the arc of the screen is formed on the edge by the characteristics of the hard screen protector, so that the hard screen protector can cover the entire arc edge Screen.

However, since the hard screen protector cannot follow the unevenness of the screen surface like the soft screen protector, the surface of the hard screen protector and the surface of the arc screen cannot be completely adhered to each other. There will be a lot of gaps, that is, there will be many bubbles that cannot be pushed and vented between the hard screen protector and the arc-side screen, which has long been criticized for a long time.

Therefore, how to design a invention which can improve the above-mentioned defects is a major problem that the inventors of the present invention are trying to solve.
