Description

Technical Field

[0001] The utility model relates to the technical field of protective films, in particular to a protective film with an AF coating for a cover plate. Background Art

[0002] The function of the protective film is to put a layer of film on the physical object we want to protect. With the popularity of digital products such as mobile phones, the protective film has gradually become a general term for screen protectors.

[0003] Cover plate surface treatments include AG, AR, and AF. These can be used individually or in combination to achieve different display and performance characteristics for LCD products. The choice of surface treatment for the cover plate is determined based on factors such as the LCD product's operating conditions and intended user.

[0004] However, in existing technologies, if the cover plate surface is not treated with AF, bubbles will form when the protective film is applied to the cover plate (generally, bubbles will appear even without AF surface treatment). Under high temperature conditions, bubbles will be printed on the cover plate, causing the cover plate to look unsightly. Although AF treatment can be used to solve this problem, this method is costly and relatively cumbersome. Therefore, to solve this problem, we have designed a protective film with AF coating for cover plates. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings, the present invention aims to provide a technical solution that can solve the above-mentioned problems.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a protective film for a cover plate with an AF coating, comprising a film body, wherein the film body comprises a peeling film 1, a protective film and a peeling film 2; the protective film is arranged between the peeling film 1 and the peeling film 2; one side of the protective film is sprayed with an AF coating, and the edge of the protective film close to the AF coating is provided with a sticky glue in a ring shape.

[0007] As a further solution of the present invention: a protective cavity is formed between the peeling film 1 and the peeling film 2 after they are bonded together, the protective film is placed in the protective cavity, and one side of the protective film is bonded to the peeling film 1, and the other side of the protective film is bonded to the peeling film 2.

[0008] As a further solution of the present invention: the AF coating is sprayed on the middle part of the protective film close to the second side of the peeling film, and the widths from the four sides of the AF coating to the four sides of the protective film are the same.

[0009] As a further solution of the present invention: the width between the four sides of the AF coating and the four sides of the protective film is greater than or equal to 20 mm.

[0010] As a further solution of the present invention: a positioning groove is provided on one side of the peeling film 1 close to the peeling film 2 and close to the edge, and a positioning strip is integrally formed on the one side of the peeling film 2 close to the peeling film 1 and at a position corresponding to the positioning groove.

[0011] As a further solution of the present invention, the size of the positioning strip is adapted to the size of the positioning groove, and when the peeling film 1 and the peeling film 2 are attached to each other, the positioning strip is adhered to the inside of the positioning groove.

[0012] As a further solution of the present invention: a hand-tear handle 1 is integrally formed on the left top of the peeling film 1, and a hand-tear handle 2 is integrally formed on the right bottom of the peeling film 2.

[0013] As a further solution of the present invention: the tear handle 1 and the tear handle 2 are both convex, and the thickness of the tear handle 1 is the same as the thickness of the peeling film 1, and the thickness of the tear handle 2 is the same as the thickness of the peeling film 2.

[0014] As a further solution of the present invention: the thickness of the adhesive is the same as the thickness of the AF coating. After the adhesive and the AF coating are provided on one side of the protective film, the side is in a flat state.

[0015] As a further solution of the utility model: it also includes a cover plate and a backlight liquid crystal display panel, the backlight liquid crystal display panel is installed on one side of the cover plate, and the protective film is attached to the other side of the cover plate.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. In the present application, a layer of AF coating is sprayed on the middle position of the contact surface between the protective film and the cover plate, replacing the current solution of adding AF surface treatment on the cover plate. This can also solve the problem of bubbles when the cover plate and the protective film are bonded together. There will be no bubble marks under high temperature conditions. Compared with adding AF coating on the cover plate, spraying AF coating on the protective film will be cheaper, and the operation will be simpler and the required precision will be lower. At the same time, by providing weak adhesive on the protective film, the protective film can be prevented from falling off the cover plate.

[0018] 2. In the present application, by adding a peeling film 1 and a peeling film 2 on both sides of the protective film respectively, the protective film can be sealed and protected in a wrapped form when the protective film is not in use, thereby ensuring the complete functionality of the protective film in the later stage. The edges of the peeling film 1 and the peeling film 2 are designed to be fitted with positioning grooves and positioning strips. On the one hand, the contact area between the peeling film 1 and the peeling film 2 can be increased to improve the fit. On the other hand, the positioning effect of the peeling film 1 and the peeling film 2 when they are closed can be improved during production, and misalignment or distortion can be avoided when the peeling film 1 and the peeling film 2 are closed, thereby ensuring that the gap between the peeling film 1 and the peeling film 2 can completely protect the protective film.

[0027] 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 embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-6A protective film for a cover plate with an AF coating includes a film body 1, which includes a peeling film 2, a protective film 3 and a peeling film 4; the protective film 3 is arranged between the peeling film 2 and the peeling film 4; one side of the protective film 3 is sprayed with an AF coating 301, and the edge of the protective film 3 close to the AF coating 301 is provided with a ring-shaped adhesive 302.

[0029] See also Figure 2-3 In this embodiment, a protective cavity is formed between the peeling film 1 2 and the peeling film 2 4 after they are bonded together, and the protective film 3 is placed in the protective cavity, with one side of the protective film 3 attached to the peeling film 1 2 and the other side of the protective film 3 attached to the peeling film 2 4.

[0030] Specifically, the peeling film 1 2 and the peeling film 2 4 can both be release films. The function of the peeling film 1 2 and the peeling film 2 4 is mainly to provide sealing protection for the protective film 3, which can ensure that the protective film 3 does not come into contact with the outside world when not in use or during transportation, thereby ensuring the functionality of the protective film 3.

[0031] See also Figure 4 In this embodiment, the AF coating 301 is sprayed on the middle part of the protective film 3 close to the peeling film 2 4, and the widths between the four sides of the AF coating 301 and the four sides of the protective film 3 are the same; the widths between the four sides of the AF coating 301 and the four sides of the protective film 3 are greater than or equal to 20 mm.

[0032] Specifically, when the cover plate 5 is not subjected to AF surface treatment, the bubbles (bubble marks) are mainly concentrated in the middle part. When the protective film 3 after AF treatment is used, AF spraying can be performed on the middle part of the protective film 3. There is a space greater than or equal to 20 mm on all four sides of the AF coating 301, which makes it convenient to evenly apply the adhesive 302.

[0033] See also Figure 3-5 In this embodiment, a positioning groove 201 is provided on one side of the peeling film 2 4 near the edge thereof, and a positioning strip 401 is integrally formed on the one side of the peeling film 2 4 near the peeling film 1 2 and at a position corresponding to the positioning groove 201; the size of the positioning strip 401 is adapted to the size of the positioning groove 201, and when the peeling film 1 2 and the peeling film 2 4 are attached to each other, the positioning strip 401 is adhered to the inside of the positioning groove 201.

[0034] Specifically, through the designed positioning groove 201 and positioning strip 401, when the peeling film 1 2 and the peeling film 2 4 are bonded together, the positioning strip 401 can enter the positioning groove 201, which on the one hand improves the positioning effect when the two are bonded together, ensures that neither side of the peeling film 1 2 nor the peeling film 2 4 protrudes, thereby ensuring the integrity; on the other hand, it can increase the contact area between the peeling film 1 2 and the peeling film 2 4, thereby improving the stability after bonding.

[0035] See also Figure 4-5 In this embodiment, a tear handle 1 202 is integrally formed on the left top of the peeling film 1 2, and a tear handle 2 402 is integrally formed on the right bottom of the peeling film 2 4; the tear handle 1 202 and the tear handle 2 402 are both convex in shape, and the thickness of the tear handle 1 202 is the same as the thickness of the peeling film 1 2, and the thickness of the tear handle 2 402 is the same as the thickness of the peeling film 2 4.

[0036] Specifically, by designing the tear handle 1 202 and the tear handle 2 402, the peeling film 1 2 and the peeling film 2 4 can be easily torn off from the protective film 3, thereby facilitating the attachment of the protective film 3 to the cover plate 5. The thickness of the tear handle 1 202 is the same as that of the peeling film 1 2, and the thickness of the tear handle 2 402 is the same as that of the peeling film 2 4, so that the peeling film 1 2 and the peeling film 2 4 can be directly lifted up when tearing.

[0037] See also Figure 2-3 In this embodiment, the thickness of the adhesive 302 is the same as the thickness of the AF coating 301. After the adhesive 302 and the AF coating 301 are set on one side of the protective film 3, the side is in a flat state.

[0038] Specifically, the above design can ensure that one side of the protective film 3 is in a flat state, thereby ensuring that this side of the protective film 3 can be completely attached to the cover plate 5, ensuring the firmness after attachment, and avoiding the occurrence of bubbles.

[0039] See also Figure 6 In this embodiment, a cover plate 5 and a backlight liquid crystal display panel 6 are also included. The backlight liquid crystal display panel 6 is installed on one side of the cover plate 5, and the protective film 3 is attached to the other side of the cover plate 5.

[0040] Specifically, the cover plate 5 is protected by the protective film 3 of this design, which not only avoids the occurrence of bubbles but also ensures the beauty of the cover plate 5.

[0041] During use: first, grasp the tear handle 2 402 and tear off the peeling film 2 4 from the protective film 3, then stick the protective film 3 on the cover plate 5, and gently press the protective film 3 as a whole to make it firmly stick. After sticking, grasp the tear handle 1 202 and tear off the peeling film 1 2 from the protective film 3. At this time, the protective film can be completely stuck on the cover plate 5, and the AF coating 301 can prevent bubbles from forming.
