In addition, the introduction of intelligent touch control will also result in the entire surface of products such as mobile phones being the screen, which is very likely to break. Therefore, most people will attach a layer of protective film to the surface of the screen when using the above-mentioned touch-function screen. Existing protective films mainly include tempered films, hydrogel films, etc. Tempered films are widely used because they have high drop resistance and impact resistance, and their surfaces have high smoothness. However, when using tempered films, they are often damaged due to bumps on the edges, especially the corners are easily broken, or white edges appear on the edges after a period of use, affecting the aesthetics. In this regard, it is necessary to propose an improved technical solution to solve the above problems. Utility Model Content
