Description

Technical Field

[0001] The utility model belongs to the technical field of protective films, and in particular relates to a multifunctional protective film for a display screen. Background Art

[0002] A protective film is also called a protective sticker or film. It is a thin film that is attached to the screen of electronic products (such as mobile phones, computers, etc.). It can effectively protect the screen from being scratched, dirty, or fingerprinted, which will affect the use effect. Therefore, a protective film can better protect the screen, avoid damage caused by daily use, and increase the life and aesthetic effect of the device.

[0003] There are many types of protective films on the market, such as transparent protective films, explosion-proof films, breathable protective films, and electrostatic films. However, the above protective films have more or less the following disadvantages when used: the protective films are difficult to fit, and some require the use of jigs to fit them; some protective films have very high requirements for the fitting environment, and dust spots will cause poor appearance; some protective films are made of glass, and under the action of external forces, the protective films will break and splash, and the safety is relatively poor.

[0004] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art. Utility Model Content

[0005] The purpose of the utility model is to provide a multifunctional protective film for a display screen, which can solve the problems in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the technical solution provided by a specific embodiment of the utility model is as follows:

[0007] A multifunctional protective film for a display screen comprises a substrate layer, a low-viscosity glue layer is adhered to the bottom surface of the substrate layer, a surface treatment layer is adhered to the side of the substrate layer away from the low-viscosity glue layer, a protective layer is adhered to the surface treatment layer, a pair of positioning films are adhered to the protective layer, and the ends of the pair of positioning films away from each other are each provided with a positioning end, a second release film layer is adhered to the positioning end, the second release film layer is arranged on the lower end surface of the positioning film, and a first release film layer is adhered to the low-viscosity glue layer.

[0008] In one or more embodiments of the utility model, the substrate layer is a polyurethane elastomer layer. By utilizing the moderate hardness and softness of the polyurethane elastomer layer, the protective film as a whole can be well adhered to the surface of the display screen, making it difficult for the protective film to rebound and fall off. At the same time, the polyurethane elastomer is also elastic and acts as a buffer when falling, which can further enhance the protection of the display screen.

[0009] In one or more embodiments of the utility model, the low-viscosity glue layer is acrylic pressure-sensitive adhesive or silicone. Acrylic pressure-sensitive adhesive or silicone can be repeatedly bonded, and even if there is fine dust on the surface of the display screen, it can be easily covered. If the acrylic pressure-sensitive adhesive or silicone comes into contact with debris, it can be cleaned by rinsing with tap water. After drying, it can still be used normally. At the same time, acrylic pressure-sensitive adhesive or silicone also has excellent characteristics such as good temperature resistance, good flame retardancy, anti-aging, anti-oxidation and corrosion resistance.

[0010] In one or more embodiments of the utility model, the surface treatment layer includes a base film, and a hardening layer, an anti-glare layer and a hydrophobic layer are sequentially provided on the upper side of the base film. The hardening layer can increase the overall hardness of the protective film, the anti-glare layer can increase the overall anti-glare effect of the protective film, and the hydrophobic layer can increase the overall anti-oil and anti-fingerprint capabilities of the protective film.

[0011] In one or more embodiments of the present invention, adhesive layers are adhered to the surfaces of the base film and the hydrophobic layer, and a pair of the adhesive layers are adhered to the substrate layer and the protective layer respectively.

[0012] In one or more embodiments of the present invention, the protective layer is made of polyester film material, which has good permeability, and the thickness of the protective layer is 10-150 μm.

[0013] Compared with the prior art, the utility model provides a multifunctional protective film for a display screen, which adopts low-viscosity glue and can be repeatedly aligned and bonded without the aid of a jig, thereby reducing costs and facilitating operation; the glue has a strong covering ability and can easily cover fine dust on the surface of the attached display screen; the surface of the protective film is treated with anti-glare, hardening, and anti-oil and anti-fingerprint treatments.

[0020] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0021] like Figure 1-Figure 3 As shown, a multifunctional protective film for a display screen in one embodiment of the utility model comprises a substrate layer 1, a low-viscosity glue layer 2, a surface treatment layer 3, a protective layer 4 and a first release film layer 5.

[0022] Among them, the substrate layer 1 is a polyurethane elastomer layer. By utilizing the moderate hardness and softness of the polyurethane elastomer layer, the protective film as a whole can be well adhered to the surface of the display screen, making it difficult for the protective film to rebound and fall off. At the same time, the polyurethane elastomer is also elastic and acts as a buffer when falling, which can further enhance the protection of the display screen.

[0023] like Figure 1-Figure 3 As shown, a low-viscosity glue layer 2 is adhered to the bottom surface of the substrate layer 1. The low-viscosity glue layer 2 is acrylic pressure-sensitive adhesive or silicone. The acrylic pressure-sensitive adhesive or silicone can be repeatedly bonded, and even if there is fine dust on the surface of the display screen, it can be easily covered. If the acrylic pressure-sensitive adhesive or silicone contacts with debris, it can be cleaned by rinsing with tap water. After wiping clean, it can still be used normally. At the same time, the acrylic pressure-sensitive adhesive or silicone also has excellent characteristics such as good temperature resistance, good flame retardancy, anti-aging, anti-oxidation and corrosion resistance.

[0024] like Figure 1-Figure 3 As shown, a surface treatment layer 3 is adhered to one side of the substrate layer 1 away from the low-viscosity glue layer 2. The surface treatment layer 3 can protect the substrate layer 1, thereby increasing the service life of the entire protective film.

[0025] The surface treatment layer 3 includes a base film 301, and a hardening layer 302, an anti-glare layer 303 and a hydrophobic layer 304 are sequentially arranged on the upper side of the base film 301. The hardening layer 302 can increase the hardness of the protective film as a whole, the anti-glare layer 303 can increase the anti-glare effect of the protective film as a whole, and the hydrophobic layer 304 can increase the anti-oil and anti-fingerprint capabilities of the protective film as a whole.

[0026] Preferably, the hardening layer 302 is an HC hardening treatment layer, the anti-glare layer 303 is an AG anti-glare treatment layer, and the hydrophobic layer 304 is an AF anti-oil and anti-fingerprint treatment layer.

[0027] In addition, adhesive layers 305 are adhered to the surfaces of the base film 301 and the hydrophobic layer 304 . A pair of adhesive layers 305 are adhered to the substrate layer 1 and the protective layer 4 respectively. The surface treatment layer 3 can be adhered and fixed to the substrate layer 1 and the protective layer 4 through the adhesive layers 305 .

[0028] like Figure 1-Figure 3 As shown, a protective layer 4 is attached to the surface treatment layer 3. The protective layer 4 is made of a polyester film material. The polyester film material has good permeability. The thickness of the protective layer 4 is 10-150 μm.

[0029] A pair of positioning films 401 are attached to the protective layer 4, and positioning ends are provided at the ends of the pair of positioning films 401 that are away from each other. When in use, the protective film can be attached by attaching the positioning ends to the two ends of the display screen respectively, without the need for a jig, which can reduce costs and facilitate operation.

[0030] In addition, a second release film layer is adhered to the positioning end, and the second release film layer is arranged on the lower end surface of the positioning film 401. The second release film layer can protect the positioning end, making it difficult for impurities to adhere to the positioning end, so as to position and fit the protective film.

[0031] like Figure 1-Figure 3 As shown, a first release film layer 5 is attached to the low-viscosity glue layer 2 , and the first release film layer 5 can be used to protect the low-viscosity glue layer 2 .

[0032] In specific use, when the protective film needs to be attached, first clean the display screen, then tear off the first release film layer 5 from the low-viscosity glue layer 2, adhere the positioning end of one of the positioning films 401 to the side wall of one end of the display screen, and adjust the protective film so that the protective film is aligned with the display screen. Then adhere the positioning end of another positioning film 401 to the side wall of one end of the display screen. At this time, the low-viscosity glue layer 2 can be attached to the display screen. Use a scraper to press the protective layer 4 so that the low-viscosity glue layer 2 is fully attached to the display screen. If there are slight impurities on the display screen, it will not affect the attachment effect of the low-viscosity glue layer 2.

[0033] If the protective film is attached crookedly, the positioning film 401 can be used to remove the low-viscosity glue layer 2 from the display screen, and the position can be adjusted and re-attached. After the attachment is completed, the positioning film 401 can be torn off from the surface treatment layer 3.

[0034] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.

[0035] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
