[0001] The present application relates to the technical field of mobile phone screen protection, and in particular to a mobile phone peep-proof film with a dynamic island area filling structure. BACKGROUND

[0002] In the use process of a mobile phone, some users often paste a peep-proof film on the surface of the mobile phone to prevent others from peeking at the display content of the mobile phone screen from the side, so as to prevent others from peeking at the screen picture of the mobile phone. However, in the use process of the peep-proof film, the peep-proof film will affect the transmission of light, and the peep-proof film is often provided with an opening at the position of the front camera of the mobile phone, so that the front camera of the mobile phone can achieve better shooting effect. However, in the use process, it is easy to cause the problems of dust entering, opening dust accumulation and lens scratching. CONTENT OF THE UTILITY MODEL

[0003] In order to solve the problem that the opening on the existing peep-proof film is easy to accumulate dust, the present application provides a mobile phone peep-proof film with a dynamic island area filling structure.

[0004] The mobile phone peep-proof film with a dynamic island area filling structure provided by the present application adopts the following technical scheme:

[0005] The mobile phone peep-proof film with a dynamic island area filling structure comprises a peep-proof film body, and the peep-proof film body comprises:

[0006] a base material layer;

[0007] a peep-proof layer covering the base material layer, the peep-proof layer having a light directional control structure;

[0008] a surface treatment layer covering the peep-proof layer;

[0009] a filling structure, the peep-proof film body being provided with a filling area corresponding to a dynamic island area, and the filling structure covering the filling area; a groove is formed in the inner wall of the filling area, and a protrusion is arranged on the outer wall of the filling structure and embedded in the groove.

[0010] By limiting the size range of the filling area, the filling area can accurately adapt to the dynamic island area of different mobile phone models, the adhesion of the filling structure to the mobile phone screen is ensured, visual deviation or inconvenience caused by size deviation is avoided, and reasonable size reference is provided for the structural design of the filling area, so as to ensure the reliability and practicability in actual application.

[0011] In some embodiments, the peep-proof film body comprises a first direction and a second direction perpendicular to each other, the filling area has a waist-shaped groove structure, the filling area has a length L mm in the first direction, and satisfies: 7.0≤L≤8.0, and the filling area has a width W mm in the second direction, and satisfies: 5.9≤W≤6.2.

[0012] By adopting the above technical solution, and by setting a filling structure to cover the filling area, and by locking the filling structure and the filling area through the cooperation of grooves and protrusions, it is possible to effectively prevent dust and impurities from accumulating in the filling area, while ensuring good light transmittance, making it convenient to use, and improving the bonding strength between the filling structure and the privacy film body, thereby enhancing the overall structural stability of the privacy film.

[0013] In some embodiments, the filling area includes a first arc-shaped groove, a second arc-shaped groove, and a connecting groove. The first arc-shaped groove and the second arc-shaped groove are respectively disposed at both ends of the connecting groove. The orthographic projection of the first arc-shaped groove and the second arc-shaped groove are both semi-circular, and the orthographic projection of the connecting groove is rectangular.

[0014] By adopting the above technical solution, the filling area adopts a structural design of a first arc-shaped groove, a second arc-shaped groove, and a connecting groove, which can better fit the shape of the dynamic island area, reduce the refraction and reflection of light at the edge of the filling area, reduce visual interference, and improve the screen display effect. At the same time, this structural design is also conducive to the installation and fixation of the filling structure, ensuring the stability of the filling structure during use.

[0015] In some embodiments, a first rounded corner is provided on the side of the filling area closest to the substrate layer, and the radius of the first rounded corner is R1 mm, satisfying: 0.2≤R1≤0.5; a second rounded corner is provided on the side of the filling area away from the substrate layer, and the radius of the second rounded corner is R2 mm, satisfying: 0.5≤R2≤1.2.

[0016] By adopting the above technical solution, a first rounded corner and a second rounded corner are set. The first rounded corner can preferentially disperse internal stress, ensure that the inner edge of the hole is smooth, and avoid stress concentration that causes radial cracks. The second rounded corner can expand the stress dispersion range and resist drop impact, thereby improving the impact resistance and service life of the privacy film and enhancing its durability in actual use.

[0017] In some embodiments, the filling structure is a polyester film with a thickness of 0.1 mm.

[0018] By adopting the above technical solution, the filling structure is limited to a polyester film with a specific thickness and light transmittance. The polyester film has good optical and mechanical properties, which can ensure the light transmittance of the filling area and meet the normal use requirements of components such as the front camera of the mobile phone. At the same time, its thickness is moderate and will not affect the overall thickness and use effect of the privacy film, thus ensuring the thinness and aesthetics of the privacy film.

[0019] In some embodiments, the privacy film body includes a magnetic part and a central part, the magnetic part is disposed at the edge of the central part, a magnet is embedded in the magnetic part, and the magnetic part cooperates with the magnetic module at the edge of the mobile phone case or the mobile phone screen.

[0020] By adopting the above technical solution and setting up a magnetic attachment, the privacy film body can cooperate with the magnetic module on the edge of the phone case or phone screen, realizing the quick installation and removal of the privacy film body. This allows users to repeatedly install and remove the privacy film as needed, improving the convenience and flexibility of using the privacy film and enhancing the user experience.

[0021] In some embodiments, a buffer layer is provided at the edge of the privacy film body, and the buffer layer covers the privacy film body.

[0022] By adopting the above technical solution, a buffer layer is set at the edge of the privacy film body. The buffer layer can improve the bending resistance of the privacy film body, protect the edge of the privacy film body, and reduce damage caused by bending or collision. At the same time, the buffer layer can also play a certain buffering role, reduce the impact of external impact on the privacy film body, and improve the service life and reliability of the privacy film.

[0023] In some implementations, the edge of the privacy film body is provided with a snap fastener for engaging with the phone frame.

[0024] By adopting the above technical solution, a buckle is set to engage with the phone frame or phone case, enabling a detachable connection between the privacy film body and the phone. This facilitates the installation and removal of the privacy film body, further improving the ease of use of the privacy film. At the same time, it ensures the stability of the privacy film during use, preventing it from loosening or falling off due to external forces.

[0025] In some embodiments, the surface of the filling structure is provided with an anti-fingerprint coating.

[0026] By adopting the above technical solution, the anti-fingerprint coating can effectively reduce the adhesion of fingerprints and stains, improve the visual clarity and aesthetics of the screen, and facilitate cleaning and maintenance, further enhancing the user experience.

[0027] In some embodiments, a groove is provided on the side of the substrate layer away from the privacy shield, and the groove is used to expel air bubbles.

[0028] By adopting the above technical solution, a groove is set on the side of the substrate layer away from the privacy layer to expel air bubbles. This effectively avoids air bubble residue generated during the application of the privacy film, ensuring a tight fit between the privacy film and the mobile phone screen, improving the screen display effect, and also facilitating the installation process of the privacy film, reducing installation failures or reinstallation caused by air bubbles, and improving the installation efficiency and quality of the privacy film.

[0029] Compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0030] 1. By setting a filling structure to cover the filling area, the problems of existing privacy films such as easy dust accumulation, poor light transmission, and structural instability in the dynamic island area are effectively solved;

[0031] 2. The specific shape design and size range of the filling area allow it to accurately fit the dynamic island area of ​​different mobile phone models, ensuring the fit between the filling structure and the mobile phone screen. At the same time, the combination of grooves and bumps improves the bonding strength between the filling structure and the privacy film body.

[0032] 3. The magnetic suction part, buffer layer, and buckle structure of the privacy film body further improve the ease of use, impact resistance and stability of the privacy film, and enhance the user experience. Attached Figure Description
