[0036] With the accelerating speed of the replacement of electronic products, people's demand for the protection of electronic products such as mobile phones is increasing day by day, and applying a film has become an important means of protecting the screen. However, after the existing screen protection film is applied to the screen, air bubbles are likely to appear inside the film, thus affecting the film application effect.
[0037] To solve this technical problem, the present utility model proposes a screen protection film 100 for applying film protection to the screen of a device to be film-applied, and the device to be film-applied includes but is not limited to mobile phones and tablets.
[0038] Please refer to Figures 1 to 6, in an embodiment of the present utility model, the screen protector 100 includes a film body 10, a first release film 20 and a second release film 30 respectively attached to opposite sides of the film body 10. The film body 10 includes a tempered glass layer 11, an explosion-proof layer 12 and an adhesive layer 14. The tempered glass layer 11 includes a flat protection portion 111 and a curved protection portion 112 disposed outside the flat protection portion 111. The first release film 20 is attached to the front of the tempered glass layer 11; the explosion-proof layer 12 is disposed on the back of the tempered glass layer 11, and a dot layer 13 is disposed on the back of the explosion-proof layer 12, and at least part of the dot layer 13 is disposed corresponding to the curved protection portion 112; the second release film 30 is bonded to the back of the flat protection portion 111 or the side of the explosion-proof layer 12 where the dot layer 13 is disposed through the adhesive layer 14; at least part of the dot layer 13 is located outside the adhesive layer 14, so that bubbles in the film can be effectively reduced, and the film application effect and film application quality can be improved.
[0039] In the technical solution of the present utility model, the screen protector 100 can be fully applied to the screen of the device to be filmed, so as to achieve full-screen protection of the screen. Among them, the adhesive layer 14 of the film body 10 is used to bond the screen and is disposed corresponding to the flat protection portion 111 of the tempered glass layer 11, so that when the screen protector 100 is applied to the screen, the adhesive layer is cemented in the flat area of the screen. And because at least part of the dot layer 13 is disposed outside the adhesive layer 14 and is disposed corresponding to the curved protection portion 112, that is, an exhaust spacing 103 is formed between the adhesive layer 14 and the curved protection portion 112, an exhaust gap can be formed between the dot layer 13 outside the adhesive layer 14 and the curved area of the screen. Furthermore, the bubbles formed between the flat protection portion 111 and the flat area can be quickly pushed to the exhaust gap between the curved protection portion 112 and the curved area, improving the film application effect and at the same time, helping to improve the touch effect and explosion-proof effect at the curved area.
[0040] It should be noted that the front of each layer in the present utility model is the surface pointed by the front arrow in Figure 2 or Figure 5 . Specifically, it is the side of the tempered glass layer 11, the explosion-proof layer 12 and the adhesive layer 14 facing away from the screen after filming; the back of each layer in the present utility model is the surface pointed by the back arrow in Figure 2 or Figure 5 . Specifically, it is the side of the tempered glass layer 11, the explosion-proof layer 12 and the adhesive layer 14 facing the screen after filming.
[0041] Since the tempered glass layer 11 includes a flat protection portion 111 and a curved protection portion 112, to ensure the film application quality, the curvature of the curved protection portion 112 is adapted to the curved area of the screen, that is, the cross-sectional contour lines of the two are parallel to each other, ensuring the fitting degree when the screen protector 100 is applied to the screen.
[0042] The screen protector 100 and the screen are adhered by an adhesive layer 14 provided between the planar protection portion 111 and the planar area or an adhesive layer 14 between the explosion-proof layer 12 and the planar area. At this time, since the adhesive layer 14 is provided corresponding to the planar protection portion 111 and a dot layer is provided outside the adhesive layer 14, an exhaust gap can be formed between the curved surface protection portion 112 and the curved surface area due to the absence of the adhesive layer 14, facilitating the discharge of the bubbles formed at the adhesive layer 14.
[0043] The first release film 20 and the second release film 30 are used to protect the film body 10 when transporting the screen protector 100. During the film application process, the second release film 30 and the first release film 20 need to be peeled off in sequence.
[0044] Please refer to Figures 1 to 3 , in an embodiment of the present invention, the explosion-proof layer 12 includes a planar explosion-proof protection portion 121 provided between the adhesive layer 14 and the planar protection portion 111, and a curved surface explosion-proof protection portion 122 provided outside the planar explosion-proof protection portion 121. The dot layer 13 is provided on the reverse sides of both the planar explosion-proof protection portion 121 and the curved surface explosion-proof protection portion 122; it can be understood that the explosion-proof layer 12 specifically includes a planar explosion-proof protection portion 121 and a curved surface explosion-proof protection portion 122 provided outside the planar explosion-proof protection portion 121, and at least part of the dot layer is provided corresponding to the curved surface protection portion 112, that is, at least provided on the curved surface explosion-proof protection portion 122. In this way, the touch effect at the curved surface area of the screen can be enhanced, and moreover, when the dot layer 13 is provided on the planar explosion-proof protection portion 121 and the curved surface explosion-proof protection portion 122, the touch effect and explosion-proof effect of the entire screen are greatly enhanced.
[0045] Among them, in an embodiment of the present invention, a first installation groove 113 is provided on the side of the planar protection portion 111 facing the adhesive layer 14, and the planar explosion-proof protection portion 121 is correspondingly provided in the first installation groove 113. In this way, the thickness of the tempered glass layer 11 at the planar protection portion 111 can be effectively reduced. At the same time, it is also convenient to increase the effective contact surface between the tempered glass layer 11 and the explosion-proof layer 12, enhance the explosion-proof effect, and also facilitate providing an installation space for the embedding of the adhesive layer 14.
[0046] Further, in the embodiment of the present utility model, a second installation groove 123 is provided on the reverse side of the planar explosion-proof protection portion 121, and the adhesive layer 14 is embedded in the second installation groove 123. With this setting, by embedding the adhesive layer 14, the thickness of the adhesive layer protruding from the reverse side of the planar explosion-proof protection portion 121 can be reduced, thereby reducing the exhaust gap between the curved explosion-proof protection portion 122 or the dot layer 13 and the curved surface area, avoiding dirt and grime accumulation in the exhaust gap, and improving the film application effect. However, in other embodiments, no first installation groove is provided on the planar protection portion 111, and a second installation groove 123 is provided on the reverse side of the planar explosion-proof protection portion 121.
[0047] Specifically, in the embodiment of the present utility model, the adhesive layer 14 bonds to the side of the planar explosion-proof protection portion 121 where the dot layer 13 is provided to further enhance the connection strength between the adhesive layer 14 and the planar explosion-proof protection portion 121.
[0048] Please refer to Figures 4 to 6 , in the embodiment of the present utility model, the adhesive layer 14 bonds to the reverse side of the planar protection portion 111, and the explosion-proof layer 12 includes a curved explosion-proof protection portion 122 disposed around the outside of the adhesive layer 14, and the dot layer 13 is disposed on the reverse side of the curved explosion-proof protection portion 122. In this way, on the basis of ensuring the exhaust effect, the dot layer 13 is as close as possible to the curved surface area, which helps to reduce the exhaust gap at the curved surface area, and improves the film application effect and the touch effect.
[0049] It can be understood that the adhesive layer 14 bonds to the reverse side of the planar protection portion 111, making the adhesive layer 14 protrude from the surface of the planar protection portion 111 facing the screen, and resulting in a relatively large exhaust gap between the curved surface protection portion 112 and the curved surface area after the screen protector 100 is attached to the screen. Therefore, as Figures 5 to 4 , the dot layer 13 and the curved explosion-proof protection portion 122 are integrally in a ring structure and are disposed outside the adhesive layer 14 to fill the exhaust gap. Furthermore, a relatively small exhaust gap is formed between the dot layer 13 and the curved surface area to ensure that the bubbles generated between the adhesive layer 14 and the planar protection portion 111 are discharged through this exhaust gap, improving the film application effect. At the same time, the touch effect and the explosion-proof effect of the curved surface area are enhanced.
[0050] Please refer to Figure 6 , in the embodiment of the present utility model, the surface of the dot layer 13 facing the second release film 30 is flush with the surface of the adhesive layer 14 facing the second release film 30, that is, the thickness of the adhesive layer 14 is the same as the total thickness of the explosion-proof layer 12 and the dot layer 13. Furthermore, during the process of discharging the bubbles at the adhesive layer 14, the bubbles can be discharged through the exhaust gap between the dot layer 13 and the curved surface area, reducing the possibility of the bubbles being blocked by the explosion-proof layer 12 or the dot layer 13, thereby improving the exhaust efficiency.
[0051] Optionally, in an embodiment of the present utility model, the thickness of the adhesive layer 14 is D1, where 0.3 mm ≤ D1 ≤ 0.6 mm. With this setting, it is convenient to reduce the overall thickness of the film body 10, and at the same time, ensure the connection strength between the film body and the screen.
[0052] Specifically, the adhesive layer 14 includes a first sheet portion 141, a first adhesive portion 142, and a second adhesive portion 143. The first sheet portion 141 is connected to the second release film 30 through the first adhesive portion 142, and the first sheet portion 141 is connected to the planar explosion-proof protection portion 121 or the planar protection portion 111 through the second adhesive portion 143 to achieve the bonding effect of the adhesive layer 14 and ensure reliable film application of the screen protector 100 to the screen. Among them, a dot layer 13 ( Figure 3 not shown in the figure) is provided between the second adhesive portion 143 and the planar explosion-proof protection portion 121.
[0053] Optionally, in an embodiment of the present utility model, the thickness of the first sheet portion 141 is d1, where 0.07 mm ≤ d1 ≤ 0.12 mm; and / or, the thickness of the first adhesive portion 142 is d2, where 0.2 mm ≤ d2 ≤ 0.4 mm; and / or, the thickness of the second adhesive portion 143 is d3, where 0.03 mm ≤ d3 ≤ 0.08 mm. In this way, the specific thickness of the adhesive layer 14 is reasonably designed to ensure a small exhaust gap between the curved surface protection portion 112 and the curved surface area, improve the fitting effect at the curved surface area, and at the same time, reduce the thickness of the screen protector 100 and improve the touch sensing effect of the device to be film-applied. The thickness direction is the direction in which the screen protector 100 faces the device to be film-applied.
[0054] Specifically, the first sheet portion 141 serves as a load-bearing structure for the first adhesive portion 142 and the second adhesive portion 143, effectively reducing the possibility of affecting the forming efficiency of the adhesive layer 14 due to the structural characteristics of the first adhesive portion 142 and the second adhesive portion 143. Among them, the thickness d1 of the first sheet portion 141 is limited between 0.07 mm and 0.12 mm, which can not only ensure the forming efficiency of the adhesive layer 14 but also reduce the overall thickness of the adhesive layer 14. Specifically, the specific values of the thickness d1 of the first sheet portion 141 include but are not limited to 0.07 mm, 0.08 mm, 0.09 mm, 0.1 mm, 0.11 mm, and 0.12 mm.
[0055] The first adhesive part 142 is connected to the second release film 30 during transportation and is connected to the flat area of the screen during the film pasting process. To avoid factors such as an increased exhaust gap caused by the excessive thickness of the first adhesive part 142, the thickness d2 of the first adhesive part 142 is limited between 0.2 mm and 0.4 mm. Some of the first adhesive part 142 can be disposed in the second installation groove 123, and the first adhesive part 142 protruding from the second installation groove 123 is used to connect the flat area of the screen. This can not only ensure the connection strength between the screen protector 100 and the screen and reduce the possibility of weak bonding ability due to the relatively thin first adhesive part 142, but also reduce the overall thickness of the adhesive layer 14. Specifically, the specific values of the thickness d2 of the first adhesive part 142 include but are not limited to 0.2 mm, 0.3 mm, and 0.4 mm. Of course, in other embodiments, the thickness of the first bonding part can be less than 0.2 mm while ensuring the bonding ability of the first adhesive part 142. Further, in the embodiments of the present invention, the first bonding part is configured as AB glue.
[0056] The second adhesive part 143 is used to connect the flat explosion-proof protection part 121 and the first sheet part 141 or to connect the flat protection part 111 and the first sheet part 141, so as to realize the integration of the adhesive layer 14 and the tempered glass layer 11, which is convenient for the film pasting operation of the screen protector 100. Among them, the thickness d3 of the second adhesive part 143 is limited between 0.03 mm and 0.08 mm, which can realize the connection between the adhesive layer 14 and the tempered glass layer 11, and at the same time, reduce the overall thickness of the adhesive layer 14. Specifically, the specific values of the thickness d3 of the second adhesive part 143 include but are not limited to 0.03 mm, 0.04 mm, 0.05 mm, 0.06 mm, 0.07 mm, and 0.08 mm. Further, in the embodiments of the present invention, the second bonding part is configured as optical glue, specifically OCA glue.
[0057] Please refer to Figures 5 to 6 , in the embodiments of the present invention, the explosion-proof layer 12 includes a curved explosion-proof protection part 122. A second sheet part 15 is connected between the curved explosion-proof protection part 122 and the dot layer 13. The thickness of the second sheet part 15 is greater than the thickness of the first sheet part 141. Among them, the second sheet part 15, the dot layer 13, and the curved explosion-proof protection part 122 as a whole form an annular structure. The second sheet part 15 serves as a load transfer structure for the curved explosion-proof protection part 122 and the dot layer 13, effectively reducing the possibility of affecting the forming efficiency of the curved explosion-proof protection part 122 and the dot layer 13 due to the structural characteristics of the curved explosion-proof protection part 122, and also facilitating the connection of the formed whole to the curved protection part 112 through the curved explosion-proof protection part 122, realizing the integration of the dot layer 13, the explosion-proof layer 12, and the tempered glass layer 11, and improving the assembly efficiency.
[0058] Among them, the thickness d4 of the second sheet portion 15 is limited to be between 0.2 mm and 0.4 mm, which can not only ensure that the curved surface explosion-proof protection portion 122 and the dot layer 13 are connected as a whole, but also ensure that the curved surface explosion-proof protection portion 122 is as close as possible to the curved surface area, reducing the formed exhaust gap 103. Specifically, the specific values of the thickness d4 of the first sheet portion 141 include but are not limited to 0.2 mm, 0.3 mm, and 0.4 mm.
[0059] Optionally, in the embodiment of the present invention, the thickness of the tempered glass layer 11 is D2, and 0.2 mm ≤ D2 ≤ 0.6 mm. It can be understood that the overall thickness of the tempered glass layer 11 is D2. When the flat protection portion 111 of the tempered glass layer 11 is provided with the first installation groove 113, the sum of the thickness of the flat protection portion 111 and the groove depth is D2. In other words, the minimum thickness of the flat protection portion 111 is 0.2 mm.
[0060] Specifically, the thickness D2 of the tempered glass layer 11 is limited to be between 0.2 mm and 0.6 mm, so as to reduce the thickness of the tempered glass layer 11 on the basis of ensuring its function, and then reduce the thickness of the screen protector 100, improving the touch sensing effect of the device to be pasted with the film. Specifically, the specific values of the thickness D2 of the tempered glass layer 11 include but are not limited to 0.2 mm, 0.3 mm, 0.4 mm, 0.5 mm, and 0.6 mm. However, in other embodiments, when the requirements of the device to be pasted with the film and the user are met, the thickness D2 of the tempered glass layer 11 can be less than 0.2 mm or greater than 0.6 mm.
[0061] Optionally, in the embodiment of the present invention, the dot layer 13 includes a plurality of dots screen-printed on the explosion-proof layer 12. In this way, by using the screen printing method, it is convenient to print the dots on the flat explosion-proof protection portion 121 and / or the curved surface explosion-proof protection portion 122 of the explosion-proof layer 12, improving the forming efficiency and forming quality of the dots.
[0062] Optionally, in an embodiment of the present utility model, the thickness of the explosion-proof layer 12 is D3, where 0.07 mm ≤ D3 ≤ 0.12 mm; and / or, the thickness of the dot layer 13 is D4, where 0.01 mm ≤ D4 ≤ 0.03 mm; so as to reduce the overall thickness of the screen protector 100 on the basis of ensuring the explosion-proof effect of the screen protector 100, and avoid increasing the overall thickness of the device to be pasted with the film due to the relatively thick screen protector 100. At the same time, the touch effect of the device to be pasted with the film is improved. Specifically, when the thickness of the explosion-proof layer 12 is greater than 0.12 mm, that is, the thickness is too thick, the overall thickness of the screen protector 100 increases; when the thickness of the explosion-proof layer 12 is less than 0.07 mm, that is, the thickness is too thin, the explosion-proof effect of the screen protector 100 is weak. Therefore, the thickness of the explosion-proof layer 12 is limited between 0.07 mm and 0.12 mm, which can not only ensure the explosion-proof effect of the screen protector 100, but also reduce the overall thickness of the screen protector 100; among them, the specific values of the thickness of the explosion-proof layer 12 include but are not limited to 0.07 mm, 0.08 mm, 0.09 mm, 0.10 mm, 0.11 mm, 0.12 mm. When the thickness of the dot layer 13 is greater than 0.01 mm, that is, the thickness is too thick, the overall thickness of the screen protector 100 increases; when the thickness of the dot layer 13 is less than 0.03 mm, that is, the thickness is too thin, the touch sensing of the screen protector 100 is weak. Therefore, the thickness of the dot layer 13 is limited between 0.01 mm and 0.03 mm, which can not only ensure the touch effect of the device to be pasted with the film, but also reduce the overall thickness of the screen protector 100; among them, the specific values of the thickness of the dot layer 13 include but are not limited to 0.01 mm, 0.02 mm, 0.03 mm.
[0063] Optionally, in an embodiment of the present utility model, in the vertical direction of the flat protection part 111, the projected thickness of the curved surface protection part 112 is D5, where 1 mm ≤ D5 ≤ 3 mm, which is convenient for adapting to the curvature of the screen of the device to be pasted with the film, thereby improving the pasting effect and pasting quality; therefore, by limiting the projected thickness D5 of the curved surface protection part 112 between 1 mm and 3 mm, the influence on the pasting effect and pasting quality caused by too large or too small projected thickness is reduced. Specifically, the specific values of the projected thickness D5 of the curved surface protection part 112 include but are not limited to 1 mm, 2 mm, 3 mm. However, in other embodiments, when the structure of the device to be pasted with the film is satisfied, the projected thickness D5 of the tempered curved surface protection part 112 can be less than 1 mm or greater than 3 mm.
[0064] Optionally, in an embodiment of the present utility model, both long side edges 101 of the flat protection part 111 are connected with the curved surface protection part 112 to protect the left curved surface area and the right curved surface area of the screen.
[0065] Further, in the embodiment of the present utility model, both short sides 102 of the planar protection part 111 are connected with the curved surface protection part 112 to protect the upper curved surface area and the lower curved surface area of the screen. However, this design is not limited thereto.
