[0005] The application example provides a light feeling self -adaptation anti -drop mobile phone film, including from bottom to top sequentially connected PET release film, AB glue layer, eye -protecting color -changing film, toughened film and AF smooth layer.

[0006] When the embodiment is implemented, the eye -protecting color -changing film perceives the ambient light change in real time and dynamically adjusts the light transmittance, and filters specific wave band light synchronously; the toughened film absorbs impact energy through geometric deformation and relieves stress concentration problems; the AF smooth layer reduces friction resistance by means of nanoscale surface treatment, and ensures smooth and accurate touch operation. The functional layers are integrated through laminating process, realizing double optimization of optical self -adaptation and physical anti -drop.

[0007] Further, the thickness of the AB glue layer, the eye -protecting color -changing film and the PET release film is 0.075mm.

[0028] The utility model will be further described in detail through specific embodiments in conjunction with the drawings.

[0029] According to one embodiment of the present application, as shown in Figs. 1-2 A light-sensitive adaptive anti-falling mobile phone film, comprising PET release film 1, AB adhesive layer 2, eye protection color-changing film 3, tempered film 4 and AF smooth layer 5 connected in order from bottom to top.

[0030] In the implementation of the present embodiment, PET release film 1 is used as a protective layer covering the surface of AB adhesive layer 2 before installation, and is torn off to expose AB adhesive layer 2 during use; AB adhesive layer 2 tightly adheres eye protection color-changing film 3 to the mobile phone screen through its double-sided adhesion, with a bonding strength of 1.5-2.0 N / cm² and a light transmittance of ≥92%; eye protection color-changing film 3 senses the ambient light intensity (50-1000 lux) in real time through its photosensitive properties, and switches the color temperature from cool light (7000K) to warm light (4000K) within 0.5 seconds, dynamically matching the comfort needs of the human eye; Tempered film 4 serves as the core load-bearing layer, with a Mohs hardness of >9H to resist scratching, and absorbs impact energy through microstructure deformation; AF smooth layer 5 is used to reduce the friction coefficient to 0.1-0.2, ensuring smooth finger touch during user operation.

[0031] Further, the thickness of AB adhesive layer 2, eye protection color-changing film 3 and PET release film 1 is 0.075mm.

[0032] In the implementation of the present embodiment, AB adhesive layer 2 uses acrylic optical adhesive, and the total thickness of eye protection color-changing film 3 and PET release film 1 is controlled within 0.225mm, which ensures bonding strength and avoids touch delay.

[0033] Further, the eye protection color-changing film 3 comprises a tungsten trioxide photosensitive layer.

[0034] When the embodiment is implemented, the tungsten trioxide photosensitive layer realizes dynamic dimming through photochromic effect. When the ultraviolet visible light band is within 380-650 nm, the light transmittance linearly decreases from 85% to 45% with the increase of light intensity, preventing the visual fatigue phenomenon caused by strong light glare and color temperature disorder. The presence of the tungsten trioxide photosensitive layer makes the mobile phone screen pasted with the mobile phone film colorless indoors, and the color will darken under the irradiation of outdoor light ultraviolet, thereby blocking part of the light and reducing the reflection of strong light to the eyes. When the light is weak, the color becomes lighter, ensuring clear vision. Similar to the effect of glasses changing color, the mobile phone screen pasted with the mobile phone film can adjust the light transmittance with the change of light, so that the eyes can quickly adapt to the surrounding light environment, avoiding the need to frequently adjust the glasses when the light changes suddenly, and reducing the impact of light changes on the eyes.

[0035] Further, the eye protection color-changing film 3 further comprises an anti-blue light coating, and the anti-blue light coating is located on the bottom surface of the tungsten trioxide photosensitive layer.

[0036] When the embodiment is implemented, the anti-blue light coating selectively blocks high-energy blue light of 415-455 nm through multi-layer interference film technology, with a blocking rate of ≥35%, while maintaining a light transmittance of >80% in other wave bands. It can effectively reduce the damage of blue light to the eyes and alleviate eye fatigue.

[0037] Further, the thickness of the tempered film 4 is 0.3-0.6 mm.

[0038] When the embodiment is implemented, the thickness of the tempered film 4 is preferably 0.4 mm, the surface compressive stress is >900 MPa, and the four-point bending strength is ≥600 N. The curvature radius R of the arc-shaped micro-curved edge is 0.3 mm, covering the edge of the mobile phone screen to the inside of the frame by 0.2 mm, thereby reducing the risk of edge cracking through stress dispersion.

[0039] Further, the four corner edges of the tempered film 4 are arc-shaped micro-curved edges with a radius of 0.1-0.5 mm.

[0040] When the embodiment is implemented, the arc-shaped micro-curved edge is formed by 3D hot bending forming process. This design makes the gap between the film layer edge and the mobile phone frame ≤0.1 mm, preventing dust or liquid from entering.

[0041] Further, the tempered film 4 has a Mohs hardness of >9H, and a honeycomb-shaped microstructure buffer layer is arranged inside.

[0042] When the embodiment is implemented, the honeycomb buffer layer forms a regular hexagonal array inside the tempered film 4 through photolithography-etching process. The microstructure deformation of the array can effectively absorb and disperse the impact load suffered by the mobile phone screen when it is hit.

[0043] Further, the single honeycomb structure of the buffer layer is a regular hexagonal structure with a side length of 50-80 μm and a wall thickness of 5-8 μm.

[0044] Further, the AF smooth layer 5 has a thickness of 0.005-0.015 mm.

[0045] In the embodiment, the AF smooth layer 5 reduces the surface friction coefficient through the nano fluorosilicon coating, improves the touch smoothness, and has the sweat stain residue prevention function, so that the surface smoothness can be maintained for a long-term use.

[0046] The above detailed description is only a specific embodiment of the present application, and is not used to limit the protection scope of the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
