Description

Technical Field

[0001] This utility model relates to the technical field of optical films, and in particular to an anti-interference privacy film. Background Technology

[0002] The core technology of privacy screen protectors originates from the optical design of micro-louvers. This innovative concept miniaturizes the traditional venetian blind structure to a size tens of thousands of times smaller and cleverly embeds it into the screen protection layer. Its operating mechanism relies on a precisely arranged grating structure, which resembles miniature venetian blind blades. By precisely controlling the angle of light incidence, it cleverly narrows the screen's wide viewing area to a very narrow viewing angle. With this design, screen content can only be clearly displayed within a specific angle from the front; once outside this range, the screen content quickly blurs, effectively building a protective barrier for personal privacy and avoiding the risk of information leakage from side-view peeping.

[0003] However, traditional privacy screen protectors face a challenge during application: because they typically require tilted application to fit the screen edges, this process often results in unavoidable interference. This interference not only increases the difficulty of application but also leads to significant waste of scrap material, affecting the economy and efficiency of material use. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose an anti-interference privacy film that effectively solves the problem of 0° interference anomaly, provides users with a more stable and reliable privacy effect, and optimizes the visual experience.

[0006] To achieve the above objectives, this utility model proposes an anti-interference privacy film, comprising a substrate, a brightening layer, a white adhesive coating, and a black adhesive coating, wherein the brightening layer is disposed on the substrate; the white adhesive coating is disposed on the brightening layer; and the black adhesive coating is disposed between two adjacent sets of white adhesive coatings.

[0007] This utility model of anti-interference privacy film effectively solves the problem of 0° interference anomaly, providing users with a more stable and reliable privacy effect while optimizing the visual experience.

[0008] In addition, the anti-interference privacy film proposed in the application may also have the following additional technical features:

[0009] Specifically, the brightening layer is a triangular prism, the distance between the tops of two adjacent sets of brightening layers is 35-45 μm, the maximum angle of the brightening layer is 70°-110°, and the height of the brightening layer is 10-30 μm.

[0010] Specifically, both the white adhesive coating and the black adhesive coating are trapezoidal prisms, the trapezoidal prisms are micron-level gratings, and the height of the trapezoidal prisms is 10–30 μm.

[0011] Specifically, it also includes a secondary prism disposed on the substrate and within the black adhesive coating.

[0012] Specifically, the height of the secondary prism is less than the height of the brightening layer.

[0013] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0019] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0020] The anti-interference privacy film of the present invention will now be described with reference to the accompanying drawings.

[0021] like Figure 1-3 As shown, the anti-interference privacy film of this utility model embodiment includes a substrate 10, a brightening layer 20, a white adhesive coating 30, and a black adhesive coating 40.

[0022] The brightening layer 20 is disposed on the substrate 10, the white adhesive coating 30 is disposed on the brightening layer 20, and the black adhesive coating 40 is disposed between two adjacent sets of white adhesive coatings 30.

[0023] Specifically, the substrate 10 is made of one of PET, PC, PU, ​​TPU, TPH, or PVC. Brightening layers 20 are spaced out, with each brightening layer 20 positioned directly below the white adhesive coating 30. The white adhesive coating 30 is made of acrylic resin and is applied in two coats: the first coat has a refractive index of 1.4–1.8 UV, and the second coat has a refractive index of 1.4–1.6 UV. The black adhesive coating 40 is a filler layer with a refractive index of 1.4–1.6 UV.

[0024] In one embodiment of this utility model, such as Figure 2 As shown, the brightening layer 20 is a triangular prism, the distance between the tops of two adjacent brightening layers 20 is 35-45 μm, the maximum angle of the brightening layer 20 is 70°-110°, and the height of the brightening layer 20 is 10-30 μm.

[0025] It should be noted that the brightening layer 20 is in the shape of a triangular pyramid, and the light source is irradiated from below the substrate 10. The light beam is focused and enhanced by the brightening layer 20, and then projected through the white adhesive coating 30.

[0026] In one embodiment of this utility model, such as Figure 1 and Figure 3 As shown, both the white adhesive coating 30 and the black adhesive coating 40 are trapezoidal prisms, which are micron-level gratings, and the height of the trapezoidal prisms is 10–30 μm.

[0027] It should be noted that the white adhesive coating 30 and the black adhesive coating 40 are distributed alternately, and the black adhesive coating 40 fills the white adhesive coating 30. Furthermore, the trapezoidal structure is used to match the white adhesive coating 30, so that the black adhesive coating 40 and the white adhesive coating 30 are integrally formed.

[0028] Specifically, the steps for applying the anti-interference privacy film are as follows: A brightness enhancement layer 20 is provided on the surface of the substrate 10. The brightness enhancement layer 20 is in the shape of a triangular pyramid and each brightness enhancement layer 20 has a white adhesive coating 30. The light source is projected from below the substrate 10, and then the light beam is focused and brightened by the brightness enhancement layer 20 before being projected. Subsequently, a black adhesive coating 40 is filled between two adjacent sets of white adhesive coatings 30, thus achieving the privacy protection effect. Furthermore, when the privacy film is applied to the screen, it is directly applied to the surface of the screen at a 0° angle, avoiding the phenomenon of excessive waste of material caused by tilted application in traditional applications.

[0029] In another embodiment of this utility model, such as Figure 3As shown, it also includes a secondary prism 50, which is disposed on the substrate 10 and in the black adhesive coating 40.

[0030] It should be noted that the secondary prism 50 is disposed in the black coating 40, and the secondary prism 50 further focuses the light beam and brightens the black coating 40, thereby enhancing the overall privacy film.

[0031] In one embodiment of this utility model, such as Figure 3 As shown, the height of the secondary prism 50 is less than the height of the brightening layer 20.

[0032] It should be noted that the height of the secondary prism 50 is less than the height of the brightening layer 20, thus ensuring slight brightening without causing glare that affects viewing.

[0033] In summary, the anti-interference privacy film of this utility model embodiment effectively solves the problem of 0° interference anomaly, provides users with a more stable and reliable privacy effect, and optimizes the visual experience.

[0034] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
