Description

Mobile phone protection film

Technical Field

The utility model discloses a mobile phone protection film.

Background

With the development of smart phones, mobile phone films have become a huge market. People can paste a layer of soft protective film or toughened glass film on the surface of a mobile phone screen in the process of using the mobile phone, so that the mobile phone screen has the functions of preventing falling and preventing the screen from being scratched.

The principle of ultrasonic fingerprint of the mobile phone of an OLED mobile phone screen (such as samsung S10 and S10Plus) is the same as that of B-ultrasonic in a hospital, ultrasonic waves are emitted by a sensor under the screen, penetrate through the OLED screen and a glass panel, and are reflected by the skin of a finger to form an image. Through the reflection signal of the uneven fingerprint, the mobile phone can obtain the 3D model information of the fingerprint. Compare the 2D fingerprint pattern that the fingerprint obtained under the optical screen, the 3D fingerprint pattern that the ultrasonic wave obtained is more meticulous, and the unblock speed is also very fast.

Fig. 1 is a schematic structural diagram of a planar toughened glass film, which includes a protective film layer 101 (which is used to protect the toughened glass layer 102 from being scratched), a toughened glass layer 102 located below the protective film layer 101 (which is used to protect the mobile phone screen from being scratched and from falling), an AB glue layer 103 (which is used to attach the toughened glass to the mobile phone screen), and a release film layer 104 (which is used to protect the AB glue layer 103 and is torn off during film attachment). Wherein the toughened glass layer 102 and the AB glue layer 103 serve as the use layer 1. When the film is pasted, the release film layer 104 is firstly torn off, the planar toughened glass film is aligned and pasted on the screen of the mobile phone, and then the protective film layer 101 is torn off, so that the film can be used.

The thickness of the toughened glass layer 102 is generally 0.20mm or 0.25mm, the thickness of the AB glue layer 103 is 0.15mm or 0.18mm, the thickness of the used layer is at least 0.35mm, the unlocking sensitivity of the OLED mobile phone is not high, the planar toughened glass film cannot fully cover the screen of the mobile phone, and the hand feeling and the visual effect are affected. In addition, the corners of the mobile phone screen cannot be protected, and the corners of the screen are easy to crack when the mobile phone is dropped.

Fig. 2 is a schematic structural diagram of a 3D full-adhesive tempered glass film, where the 3D full-adhesive tempered glass film includes a tempered glass layer 201, an AB adhesive layer 202, and a release film layer 303. The 3D full-adhesive toughened glass film has the advantages that the mobile phone screen can be fully covered, and the appearance and the hand feeling are good; the 3D all-glue toughened glass film has the defect that the AB glue 202 of the 3D all-glue toughened glass film is at least 0.45mm thick so that the laminating is free of bubbles, but the thicker AB glue can influence the sensitivity of fingerprint unlocking.

Fig. 3 is a schematic structural diagram of a 3D composite protective film, where the 3D composite protective film is generally formed by compounding TPU and PET, and has a thickness of 0.125 mm. After hot press forming, silk screen printing and adhesive tape pasting are carried out. Wherein 301 is a screen printing area of the protective film, and 302 is a protective film substrate and AB glue. The 3D composite material protective film has the advantages that the composite material base material is soft, a little thinner AB glue can be used, the thickness of the AB glue is about 0.10mm generally, the thickness of the used layer is 0.225mm, and the unlocking sensitivity is high. The 3D composite protective film has disadvantages of low material hardness, susceptibility to scratching, and inferior lubricity to glass.

Fig. 4 shows a schematic structural diagram of a full-adhesive tempered film with 3D openings, where the full-adhesive tempered film with 3D openings opens a hole in a fingerprint unlocking area, and a finger directly contacts a mobile phone screen to unlock the mobile phone screen. Wherein 401 is tempering film silk screen printing region, 402 is toughened glass and AB glue, 403 is toughened glass's trompil, and the trompil radius is 8 mm. The advantage of the full-glue tempering membrane of 3D trompil is that the pad pasting does not influence unblock sensitivity, and the shortcoming of the full-glue tempering membrane of 3D trompil is that trompil department influences feel and visual effect.

Through testing, due to the principle that the ultrasonic fingerprint unlocking of the mobile phone of the OLED mobile phone screen is achieved through reflection imaging of the sensor, the screen protection film can be unlocked smoothly only when the thickness of the using layer of the screen protection film is smaller than 0.35 mm. The protective film on the market at present can not satisfy all the requirements of high unlocking sensitivity, good vision, good hand feeling, high strength and the like, and along with the hot selling of the mobile phone, the problem that a proper toughened glass film is not available is urgently needed to be solved.
