Description

Technical Field

[0001] The utility model relates to the technical field of tempered films, and in particular to a curved screen tempered film that adopts an edge attachment method and an extended attachment structure. Background Art

[0002] Some existing mobile phones use curved screens with non-rigid glass as the base, which can have better elasticity, are not easy to break, and reduce the chance of screen wear, especially for mobile phone screens with a high touch rate; when used in mobile phones, the overall curved design of the curved screen is conducive to grip, fits better with the arc of the palm, and reduces the distance that the thumb touches the screen when operating with one hand, which theoretically helps to improve the experience of horizontal cross-screen operation on large-size screens;

[0003] However, since the curved screen has a certain curvature, it is difficult for the fixed-shape tempered film to be attached accurately and seamlessly, especially for some existing mobile phones with curved screens on all four sides. Ordinary tempered films and high-definition films will have certain dimensional tolerances, because ordinary tempered films are very flat and cannot be closely attached to the screen where there is a curvature on the edge of the screen. Therefore, generally speaking, tempered films cannot be used on curved screens. In order to enable the tempered film to be attached to the curved screen, the prior art generally adopts an edge-attached structure, that is, an adhesive is set on the edge of the tempered film. During the bonding process, the tempered film is only bonded to the curved screen through its edges, while other parts of the tempered film are in close contact with the curved screen without any stickiness. In this way, the tempered film can also be attached to the curved screen without causing problems such as bubbles. However, after the tempered film with only an attachment structure at the edge is bonded to the curved screen, the tempered film may easily fall off the curved screen, especially when it is bumped, which may easily cause the tempered film to fall off from the curved screen as a whole. Therefore, it is necessary to propose a new technical solution. Utility Model Content

[0004] The utility model aims to overcome the above-mentioned shortcomings and provide a technical solution that can solve the above-mentioned problems.

[0005] A curved screen tempered film adopting an edge attachment method and an extended attachment structure comprises a curved tempered glass layer, the edge of the curved tempered glass layer is in a curved shape, an explosion-proof film layer is attached to the lower end surface of the curved tempered glass layer, the edge of the lower end surface of the explosion-proof film layer is surrounded and attached with an adhesive edge, at least one group of opposite edges of the explosion-proof film layer are extended with an extended portion, and the adhesive edge extends to cover the lower end surface of the extended portion.

[0006] Preferably, an OCA adhesive layer is provided on the lower end surface of the curved tempered glass layer, and the explosion-proof film layer is attached to the lower end surface of the curved tempered glass layer through the OCA adhesive layer.

[0007] Preferably, the explosion-proof film layer is made of PET material.

[0008] Preferably, a circle of colored edge is silk-screened on the edge of the upper end surface of the explosion-proof membrane layer, and the colored edge corresponds to the adhesive edge.

[0009] Preferably, the front edge and the rear edge of the explosion-proof membrane layer are extended so that the front edge and the rear edge of the explosion-proof membrane layer form an extended portion.

[0010] Preferably, a hollow structure for making room is provided on the extension portion.

[0011] Preferably, the adhesive edge is made of AB glue material.

[0012] Preferably, the thickness of the curved tempered glass layer is 0.3 mm-0.4 mm, and the thickness of the explosion-proof film layer, the OCA adhesive layer and the adhesive edge are all 0.15 mm-0.20 mm.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] By utilizing the explosion-proof film layer on the curved screen tempered film, the explosion-proof film layer is extended, and an adhesive structure is set on the extended explosion-proof film layer. During the attachment process, the curved screen tempered film is first attached to the mobile phone screen through the adhesive edge. The adhesive edge enclosed on the explosion-proof film mainly plays an edge sealing role, so that dust will not enter between the curved screen tempered film and the mobile phone screen. After attachment, the extended portion of the explosion-proof film is attached along the side of the mobile phone. After attachment, the curved screen tempered film is more firm and reliable than a single extended edge enclosed.

[0015] By setting up an explosion-proof film, the curved screen tempered film will not have glass splashing after it breaks, and using the explosion-proof film for extension can make the curved screen tempered film do not need to set up other base structures to extend the adhesive structure, so that the curved screen tempered film with this feature can be minimized in thickness.

[0023] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only a 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 are within the scope of protection of the present invention.

[0024] See also Figure 1-3 In the embodiment of the utility model, the utility model uses the explosion-proof film layer 12 on the curved screen tempered film 10, extends the explosion-proof film layer 12, and sets an adhesive structure on the extended explosion-proof film layer 12. In the process of attaching, in addition to attaching the edge of the base, the extension part 14 is extended to the side of the mobile phone 20, and the curved screen tempered film 10 is attached by bonding with the side. For details, please refer to Figure 1-2 In an embodiment of the utility model, a curved screen tempered film using an edge attachment method and an extended attachment structure is proposed, including a curved tempered glass layer 11, the edge of the curved tempered glass layer 11 is in a curved shape, an explosion-proof film layer 12 is attached to the lower end surface of the curved tempered glass layer 11, and the edge of the lower end surface of the explosion-proof film layer 12 is surrounded and attached with an adhesive edge 13, the adhesive edge 13 is made of AB glue material, and can have strong adhesion to be attached to the screen of the mobile phone 20, at least one group of opposite edges of the explosion-proof film layer 12 are extended with an extension portion 14, and the adhesive edge 13 extends to cover the lower end surface of the extension portion 14.

[0025] Through this arrangement, during the attachment process, the curved screen tempered film 10 is first attached to the screen of the mobile phone 20 through the adhesive edge 13, and the adhesive edge 13 enclosed on the explosion-proof film layer 12 mainly plays an edge sealing role, so that dust will not enter between the curved screen tempered film 10 and the screen of the mobile phone 20. After attachment, the extended portion 14 of the explosion-proof film layer 12 is attached along the side of the mobile phone 20. After attachment, the curved screen tempered film 10 is more secure and reliable than a single extended edge that is enclosed;

[0026] In addition, by providing the explosion-proof film layer 12, the curved screen tempered film 10 will not have glass splashing after breaking, and the use of the explosion-proof film layer 12 for extension can make the curved screen tempered film 10 do not need to provide other base structures to extend the adhesive structure, so that the curved screen tempered film 10 with this characteristic can be minimized in thickness. Generally, the thickness of the curved tempered glass layer 11 is 0.3mm-0.4mm, and the thickness of the explosion-proof film layer 12, the OCA adhesive layer 15 and the adhesive edge 13 are all 0.15mm-0.20mm.

[0027] See also Figure 2 In the embodiment of the utility model, based on the attachment method between the curved tempered glass layer 11 and the explosion-proof film layer 12, the traditional OCA glue is used for attachment, that is, a layer of OCA glue layer 15 is provided on the lower end surface of the curved tempered glass layer 11, and the explosion-proof film layer 12 is attached to the lower end surface of the curved tempered glass layer 11 through the OCA glue layer 15; the explosion-proof film layer 12 is made of PET material; the PET explosion-proof film layer 12 is a special film, usually made of optical PET film or TPU film with high-performance optical adhesive, with excellent optical properties and strong viscosity, and can be printed. Therefore, a circle of colored edge can be silk-screened on the edge of the upper end surface of the explosion-proof film layer 12, and the colored edge corresponds to the adhesive edge 13, so that the overall aesthetic effect after attachment is better.

[0028] See also Figure 1 and Figure 3In the embodiment of the utility model, the extension 14 of the explosion-proof membrane layer 12 can be arranged in the direction of the front and rear extensions of the explosion-proof membrane layer 12, so that the front and rear of the explosion-proof membrane layer 12 form the extension 14; it can also be arranged that the left and rear of the explosion-proof membrane layer 12 are extended, so that the left and right sides of the explosion-proof membrane layer 12 form the extension 14, or the front, rear, left and right sides of the explosion-proof membrane layer 12 are all extended, so that the front, rear, left and right sides of the explosion-proof membrane layer 12 form the extension 14; the utility model is preferably in the above technical means. The front and rear edges of the explosion film layer 12 are extended, and the relative edges are used to ensure the reliability of the fixation of the curved screen tempered film 10. The front and rear edges are extended, and the extension portion 14 can be set to a minimum extent. The extension portion 14 is generally required to cover one side of the entire mobile phone 20. Since the side of the mobile phone 20 has functional devices such as buttons, listening holes, and charging holes, the extension portion 14 needs to be provided with a hollow structure 16 for making way on the extension portion 14 so as not to block the functional devices on the side wall of the above-mentioned mobile phone 20.

[0029] 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 basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, 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 are included in the present invention.
