Description

Technical Field

[0001] The present invention relates to the technical field of anti-peeping films, and specifically to an anti-peeping film assembly for teeth.

Background Art

[0002] An anti-peeping film is a thin film that uses optical technology to limit the viewing angle of a screen, and is mainly used to prevent others from peeping at the screen content from the side. The operating principle is based on the "ultrafine louver optical technology" to form a micron-order parallel grating structure (grating) inside the film, allowing only light rays in the vertical direction to pass through and blocking light rays from the side. As a result, the screen content can be clearly seen at a front angle (usually within 60°), but appears as a black screen or a blurred state from the side.

[0003] To prevent others from peeping at the computer screen from the side, an anti-peeping film is usually attached to the computer. For example, in some current computers (including notebook computers and tablet computers), a magnet is installed on the screen frame, and a magnetic adsorption component (such as an iron piece or an iron-based alloy piece) is attached to the outer surface of the anti-peeping film. When the magnetic adsorption component and the magnet (located inside the computer) are magnetically adsorbed, the anti-peeping film is positioned on the computer screen. The following problems exist in the conventional anti-peeping film.

[0004] 1. Usually, one magnetic adsorption component is installed at the top of the anti-peeping film, that is, only the top of the anti-peeping film is positioned. Therefore, the着力点 is small, the force reception is unstable, it is easy to shift during installation, the anti-peeping film does not adhere closely, the anti-peeping film is caught by the keyboard part, and the computer screen cannot be closed.

[0005] 2. Since the magnetic adsorption member is located outside the anti-peeping film, the screen is easily damaged when the computer is closed or when the computer receives an external force.

[0006] 3. Privacy films typically consist of a PET substrate, a microlouver layer, an adhesive layer, and magnetic adsorption components. The installation of magnetic adsorption components increases the weight of the surface layer of the privacy film. If the adhesive strength of the adhesive at the edges is insufficient or not uniformly distributed, the film is prone to curling due to gravity or external forces.

[0007] Thus, the inventor devised a privacy film assembly to solve the problem. [Overview of the project] [Problems that the invention aims to solve]

[0008] This invention aims to provide a privacy film assembly that addresses the shortcomings and deficiencies of the prior art by providing a privacy film assembly in which magnetic adsorption components are installed at the corners of the privacy film, thereby providing more stable force distribution, enhancing the stability and adhesion of the privacy film assembly to the computer, effectively preventing the privacy film assembly from falling off the computer, and facilitating the removal of the entire privacy film assembly from the screen along the magnetic adsorption components. [Means for solving the problem]

[0009] To achieve the above objectives, the technical means employed by this invention are as follows: A privacy film assembly comprising a privacy film and two support films, wherein the privacy film is bonded between the two support films, and an L-shaped mounting position is provided at the corner of the privacy film, a magnetic adsorption component that fits therein is fixed within the mounting position, and the two support films cover the magnetic adsorption component.

[0010] Selectively, at least two mounting positions are provided, each located at two corners of the top of the privacy film, and the thickness of the magnetic adsorption component matches the thickness of the privacy film.

[0011] Selectively, the support film includes a base layer, an anti-glare coating layer, and an OCA adhesive layer, the anti-glare coating layer and the OCA adhesive layer are provided on both sides of the base layer, and the support film is bonded to the privacy film via the OCA adhesive layer.

[0012] Selectively, the substrate layer is made of PET with a thickness of 50 to 75 μm, the anti-glare coating layer has a thickness of 5 to 12 μm and a hardness of 1 to 2H, and the OCA adhesive layer has a thickness of 15 to 30 μm and a Shore hardness of 30 to 60 SH.

[0013] Selectively, side holes are provided in the upper center portion of both the support film and the privacy film.

[0014] Selectively, each of the magnetic adsorption components has a second mounting hole, and a magnet block is fixed within each of the second mounting holes.

[0015] Selectively, the privacy film is made by compounding a privacy coating layer with PET, and the thickness of the privacy film is 0.15 to 0.25 mm.

[0016] Selectively, the magnetic adsorption component is an L-shaped manganese steel billet, and the thickness of the magnetic adsorption component is 0.15 to 0.25 mm.

[0017] Selectively, the length of one side of the manganese steel billet is one-quarter of the top length of the privacy film, and the length of the other side is one-third of the side length of the privacy film.

[0018] Selectively, decorative strips are attached to both corners of the top of the surface of the support film, and the shape and size of the decorative strips match the shape and size of the manganese steel billet. [Effects of the Invention]

[0019] After employing the above technical means, the beneficial effects of this invention are as follows.

[0020] To prevent the magnetic adsorption component from protruding from the surface of the privacy film, mounting positions for the magnetic adsorption component are provided on the side edge of the privacy film, and the thickness of the magnetic adsorption component must match the thickness of the privacy film. This effectively prevents the screen from being compressed by the presence of the magnetic adsorption component when the computer is closed, thereby enhancing safety during computer use. Magnets are installed in the frame of the computer screen, and the privacy film assembly is positioned on the computer by magnetic attraction between the magnets and the magnetic adsorption component. Support films on both sides of the privacy film provide support, and the privacy film is intended to prevent others from viewing the screen contents from the side, thereby protecting privacy.

[0021] Both the mounting position and the magnetic adsorption component are L-shaped, with at least two mounting positions provided, each located at one of the two corners of the top of the privacy film. This mounting allows for positioning on both sides of the privacy film assembly, enhancing the stability and adhesion of the privacy film assembly to the computer and effectively preventing the privacy film assembly from falling off the computer. Because the magnetic adsorption component is installed at the corners of the privacy film assembly, the force distribution is more stable, making it easier to peel the entire privacy film assembly from the screen along the magnetic adsorption component.

[0022] Since the materials of the first and third layers, the anti-glare coating layer, and the OCA adhesive layer are the same, the tension exerted by the first and third layers on the privacy film is the same, allowing the balance to be maintained over a long period of time during use. In other words, the film remains flat for a long period of time during use, and the entire privacy film assembly remains flat for a long period of time even during high-temperature and high-humidity sea transport, solving the problem of the privacy film being prone to curling due to gravity and external forces of magnetic adsorption components.

[0023] To more clearly explain the technical means in the embodiments of the present invention or the prior art, the drawings necessary for the description of the embodiments or the prior art will be briefly described below. Obviously, the drawings described below are only a part of the embodiments of the present invention, and those skilled in the art can obtain other drawings based on these drawings without the need for creative effort.

Modes for Carrying Out the Invention

[0025] The present invention will be described in more detail below with reference to the drawings.

[0026] This specific embodiment is merely an illustrative example of the present invention and does not limit the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment that do not contribute creatively as necessary, but as long as they are within the scope of the claims for utility model registration of the present invention, they will all be protected by the utility model law.

[0027] This embodiment relates to an anti-peeping film assembly. As shown in FIGS. 1 to 2, it includes an anti-peeping film 2 and two support films 1. The anti-peeping film 2 is bonded between the two support films 1, and an L-shaped mounting position 3 is provided at the corner of the anti-peeping film 2. A magnetic adsorption component 5 that fits it is fixed within the mounting position 3. The thickness of the magnetic adsorption component 5 is the same as the thickness of the anti-peeping film 2, and the two support films 1 cover the magnetic adsorption component 5.

[0028] In this embodiment, in order to prevent the magnetic adsorption component 5 from protruding from the surface of the anti-peeping film 2, mounting positions 3 for attaching the magnetic adsorption component 5 are provided on the side edge of the anti-peeping film 2. The magnetic adsorption component 5 is enclosed inside two support films 1, and the entire anti-peeping film assembly is required to be relatively thin, with the thickness of the magnetic adsorption component 5 matching the thickness of the anti-peeping film 2. This prevents gaps from forming when the screen is closed, effectively avoiding pressure on the screen due to the presence of the magnetic adsorption component 5 when the computer is closed, thereby enhancing safety when using the computer. Magnets are installed in the frame of the computer screen, and the anti-peeping film assembly is positioned on the computer by magnetic attraction between the magnets and the magnetic adsorption component 5. The support films 1 on both sides of the anti-peeping film 2 provide support to it, and the anti-peeping film 2 is intended to prevent others from peeking at the screen contents from the side, thereby protecting privacy.

[0029] Furthermore, both the mounting position 3 and the magnetic adsorption component 5 are L-shaped, and at least two mounting positions 3 are provided, each located at one of the two corners of the top of the privacy film 2. This installation allows for positioning of both sides (top and sides) of the privacy film assembly, increasing the adsorption force, fixing the privacy film 2, effectively preventing the privacy film assembly from falling off the computer, and enabling the privacy film assembly to adhere continuously, stably, and flatly to the computer screen. This effectively solves the problem where the privacy film 2 fails to adhere properly due to unstable force distribution, causing it to catch on the keyboard and preventing the computer screen from closing.

[0030] The anti-peeping film 2 reduces screen brightness and contrast, placing extra strain on the eyes' focus adjustment; therefore, users typically remove it from the screen when there are no people around or when they are in a safe area. The magnetic adsorption components 5 are placed at the corners of the anti-peeping film assembly, providing more stable force distribution and making it easier to peel the entire anti-peeping film assembly from the screen along the magnetic adsorption components 5. Specifically, as shown in Figure 4, the support film 1 includes a base layer 9, an anti-glare coating layer 10, and an OCA adhesive layer 11. The anti-glare coating layer 10 and the OCA adhesive layer 11 are provided on both sides of the base layer 9, and the support film 1 is bonded to the privacy film 2 via the OCA adhesive layer 11.

[0031] Furthermore, the base layer 9 is made of PET polyethylene terephthalate with a thickness of 50 to 75 μm, and the specific thickness may be 50 μm, 60 μm, 75 μm, etc., and is not specifically limited. PET (polyethylene terephthalate) is a polymer material that has good properties such as hardness and brittleness, high temperature resistance (long-term use temperature reaches 120°C), chemical resistance, and anti-fouling and anti-scratch properties, which can improve the service life of the anti-peeping film assembly, and the base layer 9 functions as a basic support layer. The anti-glare coating layer 10 has a thickness of 5 to 12 μm, and the specific thickness may be 5 μm, 8 μm, 10 μm, 12 μm, etc., and is not specifically limited. The anti-glare coating layer 10 is provided to reduce reflection interference of light rays, and its hardness is 1 to 2H, and it has relatively low scratch resistance. The OCA adhesive layer 11 has a thickness of 15 to 30 μm, and the specific thickness may be 15 μm, 20 μm, 25 μm, 30 μm, etc., and is not specifically limited. The OCA adhesive layer 11 is an optical-grade transparent double-sided tape used for bubble-free bonding, does not affect transmittance, and has a Shore hardness of 30-60 SH, although the specific Shore hardness may be 30 SH, 40 SH, 50 SH, 60 SH, etc., and is not specifically limited. The hardness is moderate, mitigating the impact of external forces and meeting the bonding requirements for flat and curved surfaces.

[0032] The privacy film assembly employs a three-layer composite process, which utilizes conventional technology. The first and third layers (support film 1) are PET layers of the same size, and the second layer is the privacy layer (privacy film 2). The thickness of the magnetic adsorption component 5 is the same as the thickness of the privacy film 2, and the combined dimensions of the magnetic adsorption component 5 and the privacy film 2 exactly match the dimensions of the PET layer. Since the materials of the first and third layers, the anti-glare coating layer 10, and the OCA adhesive layer 11 are all the same, the tension exerted by the first and third layers on the privacy film is the same, allowing the balance to be maintained over a long period of time during use. In other words, the entire privacy film assembly can maintain a flat state over a long period of time during use, and can also maintain a flat state over a long period of time even during high-temperature and high-humidity sea transport, thus solving the problem of the privacy film 2 being prone to warping due to gravity and external forces of the magnetic adsorption component 5.

[0033] As shown in Figures 1-3, side holes 4 are provided in the upper center of both the support film 1 and the privacy film 2. These side holes 4 are provided to avoid obstructing the camera on the computer.

[0034] As shown in Figure 3, each magnetic adsorption component 5 has a second mounting hole 8, and a magnet block 7 is fixed inside each of the second mounting holes 8.

[0035] In this embodiment, the magnetic poles of the magnet block 7 in the second mounting hole 8 that are close to the magnet on the computer are the same. When the privacy film assembly is attached, the magnet block 7 and the magnet on the computer are offset from each other, and the magnet on the computer is usually a circular point. When the privacy film assembly is moved downward, the magnet block 7 approaches the magnet on the computer, and the magnetic forces repel each other, causing the edges of the privacy film assembly to curl outwards. This makes it easier for the user to remove the privacy film assembly from the computer screen.

[0036] Furthermore, the bottom corners of the support film 1 and the privacy film 2 can be chamfered by 2.5D. This chamfer is close to the edge of the screen, and when downward pressure is applied to the privacy film assembly, the privacy film assembly can smoothly slide out from the bottom of the computer frame via the chamfered portion. At the same time, the magnet block 7 and the magnet on the computer repel each other, making it easy for the user to quickly remove the privacy film assembly from the screen.

[0037] Specifically, the privacy film 2 is made of PET polyethylene terephthalate compounded with a privacy coating layer, and the thickness of the privacy film 2 is 0.15 to 0.25 mm, and the specific thickness may be 0.15 mm, 0.20 mm, 0.25 mm, etc., and is not specifically limited. The magnetic adsorption component 5 is an L-shaped manganese steel billet, and the thickness of the magnetic adsorption component 5 is 0.15 to 0.25 mm, and the value of the thickness of the magnetic adsorption component 5 corresponds to the thickness of the privacy film 2. The manganese steel billet is an alloy steel with a manganese content of usually 11% to 14%, is a ferromagnetic material belonging to general low-alloy steel, and can be attracted by magnets. It has very high wear resistance, impact resistance and high strength, with a hardness of 500 Newtons / square meter and a tensile strength exceeding 1000 megapascals. This can improve the service life of the magnetic adsorption component 5.

[0038] Furthermore, the length of one side of the manganese steel billet is one-quarter of the top length of the privacy film 2, and the length of the other side is one-third of the side length of the privacy film 2. This allows the privacy film assembly to adhere well to the computer screen.

[0039] As shown in Figures 1 and 2, decorative strips 6 are attached to both corners of the top surface of the support film 1, and the shape and size of the decorative strips 6 match the shape and size of the manganese steel billet. This allows the manganese steel billet to be covered and the overall appearance of the product to be improved.

Any other modifications or equivalent substitutions made by those skilled in the art to the technical means of the present invention should be included within the claims of the present invention, as long as they do not deviate from the spirit and scope of the technical means of the present invention.
