Description

Technical Field

[0001] This utility model belongs to the technical field of mobile phone films, specifically relating to a semi-frosted, semi-high-definition mobile phone film. Background Technology

[0002] With the widespread use of smartphones, screen protectors, as a core accessory for screen protection and user experience optimization, are facing increasingly diverse demands in terms of function and appearance. Currently, screen protectors on the market are mainly divided into two categories: matte screen protectors and full HD screen protectors. While matte screen protectors can reduce fingerprint residue and improve touch feel, their overall light transmittance is low, which can lead to a decrease in screen display clarity, especially affecting visual needs such as video viewing and image browsing. Full HD screen protectors, on the other hand, can easily attract fingerprints and oil stains, and may feel "gritty" when touched. Furthermore, their scratch and abrasion resistance varies.

[0003] In addition, some existing screen protectors with partitioned sections (such as partial matte or partial high-definition) have obvious defects: First, the transition between partitions is abrupt, which can easily create a visual sense of discontinuity, and most of them use splicing technology, which can easily lead to edge delamination problems after long-term use; Second, they lack targeted protective structure design, either without an anti-fingerprint coating, resulting in serious fingerprint residue in the high-definition area, or without a buffer layer, which can easily cause air bubbles when applying the screen protector and has poor impact resistance; Third, the edge treatment is rough, most products do not have a special glossy edge design, which can easily cause the edges to lift when applied to the phone screen, and the adhesive compatibility of different areas is not considered, resulting in some areas not adhering firmly or leaving adhesive residue when removed.

[0004] To address the aforementioned issues, there is an urgent need for a screen protector that combines a semi-matte touch feel with a semi-high-definition visual effect and features a multi-layered protective structure, in order to overcome the shortcomings of existing products, such as limited functionality, imperfect structural design, and poor user experience. Utility Model Content

[0005] The purpose of this invention is to provide a semi-frosted, semi-high-definition mobile phone screen protector, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A semi-frosted, semi-HD mobile phone screen protector includes an anti-fingerprint coating. The lower end of the anti-fingerprint coating has a functional partition layer, the lower end of the functional partition layer has a high-transparency strengthening layer, the lower end of the high-transparency strengthening layer has a silicone buffer layer, and the lower end of the silicone buffer layer has a dedicated adhesive layer. The functional partition layer includes an upper transparent layer and a lower frosted layer. The functional partition layer is horizontally divided into an upper transparent layer and a lower frosted layer, which are integrally formed into a complete plane. Uncoated glossy edges with a width of 1mm are reserved on the left, right, and bottom edges of the screen protector. The lower frosted layer is made of AG high-aluminum material, etched by chemical immersion. The upper transparent layer 21 is made of electronic-grade glass of the same specification, polished to a clear finish. The dedicated adhesive layer is only attached to the lower surface of the silicone buffer layer corresponding to the lower frosted layer. All layers are fixedly connected by a hot-pressing composite process. After 2H tempering treatment, the entire screen protector can be folded into a U-shape.

[0007] In a preferred embodiment of this invention, the anti-fingerprint coating is a fluorine nano-coating with a thickness of 0.01-0.03 mm, completely covering the upper transparent layer and the upper surface of the lower frosted layer. Its oleophobic and hydrophobic properties reduce fingerprints and oil residue on the film surface without affecting the light transmittance of the upper transparent layer or the smooth tactile feel of the lower frosted layer.

[0008] As a preferred embodiment of this utility model, the high-transmittance strengthening layer is made of high-aluminosilicate glass with a thickness of 0.05-0.1mm, and is bonded between the functional partition layer and the silicone buffer layer, with a light transmittance ≥98%. This not only improves the overall impact resistance of the film, preventing the functional partition layer from breaking due to external impact, but also ensures that the high-definition display effect of the upper transparent layer is not weakened.

[0009] In a preferred embodiment of this invention, the silicone buffer layer has a Shore hardness of 30-40 HA, a thickness of 0.08-0.12 mm, and micron-sized venting holes on its surface. During application, air can be expelled between the film and the screen through these venting holes, preventing air bubbles from forming. Furthermore, it can cushion impacts when the phone is dropped, reducing the risk of screen damage from impact.

[0010] In a preferred embodiment of this invention, the substrate of the lower frosted layer is electronic-grade glass with a thickness of 0.25-0.4mm and a surface roughness Ra of 0.1-0.3μm, which is smooth, uniform, and free of bright spots. The frosted structure blocks strong external light reflection, achieving an anti-glare effect. Simultaneously, the smooth surface enhances the comfort of touch operations such as typing and swiping, avoiding a rough touch feel.

[0011] In a preferred embodiment of this invention, the 1mm bright edge gap is the original glass edge of the functional partition layer, which has not undergone etching, coating, or adhesive treatment, and is integrally cut and formed with the functional partition layer. This not only prevents the edge coating from peeling off after long-term use, but also adapts to the screen bezel sizes of different mobile phones, reduces friction between the film edge and the screen bezel, and lowers the probability of edge lifting.

[0012] In a preferred embodiment of this invention, the special adhesive layer is AB glue with an adhesion strength of 1.5-2.0 N / 25 mm, and its surface is covered with a peelable release film. This ensures that the lower half of the frosted layer adheres firmly to the mobile phone screen, preventing the film from shifting during use. The release film simplifies the application process, and removing the film prevents adhesive residue from contaminating the screen.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The membrane is divided into an upper transparent layer and a lower frosted layer by functional partitioning. The upper half meets the needs of high-definition vision (such as watching videos and viewing pictures), while the lower half provides a frosted touch feel. The two are integrally molded without splicing seams, avoiding a visually fragmented feeling. At the same time, 1mm original glass bright edges are reserved on the left, right and bottom sides, which not only enhances the appearance of fashion, but also solves the problem of edge curling.

[0014] 2. The newly added anti-fingerprint coating uses fluorine nanomaterials, which can simultaneously reduce fingerprint residue in the transparent area and oil stains in the matte area, solving the problem of existing films where "high-definition areas are prone to fingerprints and matte areas are difficult to clean"; the high-transparency strengthening layer uses high-aluminosilicate glass, which improves the overall impact resistance of the film without affecting the light transmittance; the micron-level vent design of the silicone buffer layer can not only prevent air bubbles from forming when applying the film, but also buffer the impact when the phone is dropped. Combined with 2H tempered treatment (which can be folded into a U-shape), it greatly improves wear resistance and scratch resistance, which is superior to the protective effect of existing single-structure mobile phone films.

[0015] 3. The special adhesive layer is only applied to the area corresponding to the frosted layer in the lower half, which ensures the adhesion of the commonly used touch area (lower half) and avoids the upper half (high-definition display area) from being left with glue when peeling off due to excessive adhesive. In addition, the adhesive layer uses AB glue, and the adhesion force is controlled at 1.5-2.0N / 25mm, which takes into account the adhesion stability and the need for repeated film application. It is suitable for the processing requirements of electronic-grade glass of different thicknesses (0.25-0.4mm) and is applicable to a variety of mobile phone models. Attached Figure Description

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0021] Reference Figure 1 , Figure 2 , Figure 3This is the first embodiment of the present invention. This embodiment provides a semi-frosted, semi-HD mobile phone screen protector, including an anti-fingerprint coating 1. The anti-fingerprint coating 1 is a fluorine nano-coating with a thickness of 0.01-0.03mm, which completely covers the upper surface of the upper transparent layer 21 and the lower frosted layer 22. It can reduce the residue of fingerprints and oil stains on the surface of the film through its oleophobic and hydrophobic properties, while not affecting the light transmittance of the upper transparent layer 21 and the smooth touch feel of the lower frosted layer 22. A functional partition layer 2 is provided at the lower end of the anti-fingerprint coating 1, and a high-transmittance strengthening layer 3 is provided at the lower end of the functional partition layer 2. The high-transmittance strengthening layer 3 is made of high-aluminosilicate glass with a thickness of 0.05-0.1mm and is attached between the functional partition layer 2 and the silicone buffer layer 4. The light transmittance is ≥98%, which can improve the overall impact resistance of the film, prevent the functional partition layer 2 from breaking due to external impact, and ensure that the HD display effect of the upper transparent layer 21 is not weakened.

[0022] Reference Figure 1 , Figure 2 , Figure 3 The lower end of the high-transparency reinforcing layer 3 is provided with a silicone buffer layer 4. The silicone buffer layer 4 has a Shore hardness of 30-40HA and a thickness of 0.08-0.12mm. The surface is provided with micron-level vent holes, which allow air to escape between the film and the screen during film application, preventing air bubbles from forming. It also cushions the impact when the phone is dropped, reducing the risk of screen damage. The lower end of the silicone buffer layer 4 is provided with a special adhesive layer 5. The special adhesive layer 5 is AB glue with an adhesion strength of 1.5-2.0N / 25mm, and its surface is covered with a peelable release film, which ensures that the lower half of the frosted layer 22 is firmly attached to the phone screen and prevents the film from shifting during use. The release film simplifies the application process and prevents adhesive residue from contaminating the screen after removal. The functional partition layer 2 includes an upper transparent layer 21 and a lower frosted layer 22. The functional partition layer 2 is divided into an upper transparent layer 21 and a lower frosted layer 22 along the horizontal direction of the film. The substrate of the lower frosted layer 22 is electronic-grade glass with a thickness of 0.25-0.4mm and a surface roughness Ra of 0.1-0.3μm. It is smooth, uniform, and without bright spots. The frosted structure can block the reflection of strong external light to achieve an anti-glare effect. At the same time, the smooth surface can improve the comfort of touch operations such as typing and swiping, and avoid the feeling of touch. The two are molded together to form a complete plane.

[0023] Reference Figure 1 , Figure 2 , Figure 3The left, right, and bottom edges of the film have 1mm wide uncoated bright edge gaps. These 1mm bright edge gaps are the original glass edges of the functional partition layer 2, which have not undergone etching, coating, or adhesive treatment. They are integrally cut and formed with the functional partition layer 2, which can prevent the edge coating from falling off after long-term use and can adapt to the screen bezel sizes of different mobile phones, reducing friction between the film edge and the screen bezel and lowering the probability of edge lifting. The lower half frosted layer 22 is made of AG high-aluminum material and is made by chemical immersion etching. The upper half transparent layer 21 is made of electronic grade glass of the same specification and is polished to be transparent. The special adhesive layer 5 is only attached to the lower surface of the silicone buffer layer 4 corresponding to the lower half frosted layer 22. The layers are fixedly connected by a hot-pressing composite process. After 2H tempering treatment, the whole can be folded into a U-shape.

[0024] During use, the layers work together. The top anti-fingerprint coating 1 is in direct contact with the outside world. Utilizing the oleophobic and hydrophobic properties of fluorine nanomaterials, it prevents fingerprints and oil from adhering to the film surface, while not affecting the touch feel of the frosted layer or the light transmittance of the transparent layer. The middle functional partition layer 2 is the core functional carrier. The upper transparent layer 21 is made of polished electronic-grade glass to ensure high-definition display. The lower frosted layer 22 is made of the same specification electronic-grade glass through chemical etching. The frosted structure of the AG high-aluminum material achieves anti-glare and smooth touch. The high-transmittance reinforcing layer 3 is located below the functional partition layer 2. Using the high strength of high-aluminum silicate glass, it provides support for the functional partition layer 2, preventing breakage when the film is bent. The silicone buffer layer 4 acts as a buffer between the reinforcing layer and the adhesive layer. Its micron-sized vents allow air to escape during film application. To prevent air bubbles from forming and absorb external impacts (such as the force of a phone being dropped), the bottom layer of dedicated adhesive layer 5 only acts on the lower half of the screen. The adhesive of the AB glue firmly bonds the lower half (the commonly used touch area) to the phone screen, while the upper half (the high-definition display area) is positioned using the micro-adhesive force of the buffer layer, preventing excessive adhesion that could leave adhesive residue when the film is removed. During processing, the electronic-grade glass is first etched with chemicals to create a frosted surface. Then, half of the protective film (corresponding to the transparent layer 21 area in the upper half) is applied, leaving the frosted surface of the lower half uncoated. The upper half is polished to a clear finish. The protective film is then removed, cleaned, and subjected to 2H tempering (giving the film the elasticity to fold into a U-shape). Finally, an anti-fingerprint coating 1, a high-transparency strengthening layer 3, and a silicone buffer layer 4 are sequentially laminated, and the dedicated adhesive layer 5 is applied to the corresponding lower half to complete the interlayer fixation. This process precisely matches the multi-layer structure, ensuring tight bonding between layers without delamination, while achieving a "half-frosted, half-high-definition" functional partitioning effect.
