Description

Technical Field

[0001] This utility model relates to the technical field of mobile phone accessories, and in particular to a special film for foldable mobile phones. Background Technology

[0002] Ultra-thin tempered glass screen protectors are high-strength protective films used to protect the screens of electronic devices such as smartphones and tablets. They enhance the hardness and impact resistance of the glass through chemical or physical tempering processes, and are typically between 0.03mm thick, combining thinness and protection. With the increasing popularity of foldable smartphones and other devices, user demand for screen protection has surged. Traditional plastic films (PET) and glass are gradually being phased out due to their fragility and inability to fold. One of the biggest technological challenges of foldable phones is the durability of the screen. Currently, many foldable phones use polymer-based screen protectors, which, while flexible, are easily scratched and can even crease. Therefore, a foldable phone screen protector with both a comfortable feel and scratch resistance is needed. Utility Model Content

[0003] The purpose of this invention is to provide a dust removal and positioning screen protector and a dedicated screen protector for mobile phones, in order to solve the problem of dust in existing screen protectors and improve the yield rate of screen protectors.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] In a first aspect, a special screen protector for foldable phones is provided. The special screen protector for foldable phones includes: a first screen tempered glass film, a second screen tempered glass film, and a folding groove. The folding groove is located between the first screen tempered glass film and the second screen tempered glass film. The position and size of the folding groove are matched with the folding part of the foldable phone. The first screen tempered glass film, the second screen tempered glass film, and the folding groove are combined to form an integral special screen protector for foldable phones. The folding groove includes: a first edge portion, a folding portion, and a second edge portion. The thickness of the tempered glass film in the first edge portion and the second edge portion is lower than the thickness of the first screen tempered glass film and the second screen tempered glass film.

[0006] Optionally, the thickness of the tempered glass layer at the first edge and the second edge is half the thickness of the tempered glass layer of the first screen tempered film and the second screen tempered film.

[0007] Optionally, the tempered glass layer thickness of the first edge portion and the second edge portion is 0.035 micrometers, and the tempered glass layer thickness of the first screen tempered film and the second screen tempered film is 0.07 micrometers.

[0008] Optionally, the folded portion includes a PET layer and an OCA layer.

[0009] Optionally, the first edge portion and the second edge portion respectively include, from top to bottom: an ultra-thin anti-slip glass layer, a first OCA layer, a PET layer and a second OCA layer.

[0010] Optionally, the first screen tempered glass film and the second screen tempered glass film respectively include, from top to bottom: a tempered glass layer, a first OCA layer, a PET layer and a second OCA layer.

[0011] Optionally, the thickness of the tempered glass layer is 0.07 micrometers, the thickness of the first OCA layer is 0.02 micrometers, the thickness of the PET layer is 0.012 micrometers, and the thickness of the second OCA layer is 0.03 micrometers.

[0012] Optionally, the thickness of the ultra-thin anti-slip glass layer is 0.03 micrometers, the thickness of the first OCA layer is 0.02 micrometers, the thickness of the PET layer is 0.012 micrometers, and the thickness of the second OCA layer is 0.03 micrometers.

[0013] The technical solution of this application includes a foldable phone screen protector: a first screen tempered glass film 10, a second screen tempered glass film 11, and a folding groove 12. The folding groove 12 is located between the first screen tempered glass film 10 and the second screen tempered glass film 11. The position and size of the folding groove 12 correspond to the folding portion of the foldable phone. The first screen tempered glass film 10, the second screen tempered glass film 11, and the folding groove 12 combine to form an integral foldable phone screen protector. The folding groove 12 includes a first edge portion 121, a folding portion 122, and a second edge portion 123. The thickness of the tempered glass film in the first edge portion 121 and the second edge portion 123 is less than the thickness of the first screen tempered glass film 10 and the second screen tempered glass film 11. By setting a folding groove in the screen protector and reducing its thickness, the folding function of the foldable phone can be effectively achieved. Compared to full-screen flexible films, the first screen tempered glass film 10 and the second screen tempered glass film 11 have better wear resistance and scratch resistance.
