Description

Technical Field

[0001] The utility model relates to the technical field of tempered films, in particular to a tempered film for a mobile phone with excellent dustproof performance. Background Art

[0002] Tempered glass (Tempered glass / Reinforced glass) is a safety glass. Glass has very good wear resistance and is very hard, with a Vickers hardness of 622 to 701. Tempered glass is actually a prestressed glass. In order to increase the strength of the glass, chemical or physical methods are usually used to form compressive stress on the surface of the glass. When the glass is subjected to external force, the surface stress is first offset, thereby increasing the bearing capacity and enhancing the glass's own resistance to wind pressure, cold and heat, impact, etc.

[0003] As people's living standards improve, more and more people use mobile phones for communication and entertainment. Since mobile phone screens are expensive and easily damaged, in order to protect the screens, tempered films are generally attached to the screens of mobile phones, and the screens of mobile phones can be controlled through the tempered films to interact with the mobile phones. In this way, when the mobile phone accidentally falls from a certain height to the ground or other flat surfaces, the tempered film can replace the screen of the mobile phone to withstand the impact force, thereby preventing the screen of the mobile phone from breaking.

[0004] The current tempered glass film for mobile phones only has a certain protective function. Its appearance is just a thin piece of glass without any special appearance and shape. After the tempered glass film is pasted on the mobile phone, it still has the disadvantages of being monotonous and not having strong practical functions. In addition, after the existing tempered glass film for mobile phones is used for a long time, dust is easily accumulated at its edge.

[0005] Therefore, it is necessary to propose an improved technical solution to solve the above problems. Utility Model Content
