Abstract
Description
Technical Field
[0001] This utility model relates to the field of display auxiliary equipment technology, and in particular to a segmented film. Background Technology
[0002] With the widespread use of mobile phones, tablets, and other electronic devices, screen display effects are constantly improving, leading to a wide variety of screen protectors. These protectors not only provide physical protection for the screen but also offer eye protection and UV protection. However, the structure of current screen protectors on the market is relatively simple, resulting in the traditional method of peeling off the entire screen protector at once. This leads to low yield rates, difficulty for non-professionals to operate, and poor application results. In particular, most mainstream screen protectors on the market consist of a release film over the main film, requiring the surface film to be peeled off and the main film directly applied to the screen. This makes it difficult to align the edges of harder films, and air bubbles and dust can easily accumulate, making application challenging. Utility Model Content
[0003] The purpose of this invention is to provide a segmented film to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A segmented film includes a surface protective film and a bottom film arranged sequentially from top to bottom. The surface protective film includes a protective film substrate and an adhesive layer, and the bottom film includes a release layer and a dust-adhesive layer. The bottom film is divided into several parts.
[0006] In a further embodiment, the surface protective film has a double-layer structure, including an upper removal layer and a lower actual use layer, each layer including the protective film substrate and adhesive layer bonded together.
[0007] In a further embodiment, the actual use layer is a film formed by performing anti-reflective AR treatment, anti-glare AG treatment, anti-blue light treatment, anti-peeping treatment, anti-fingerprint treatment, anti-scratch treatment, or self-healing treatment on the surface of PET film, PC film, PMMA film, or TAC film.
[0008] In a further embodiment, the bottom film includes a release layer, a substrate layer, an adhesive layer, and a release layer that are stacked together from top to bottom.
[0009] In a further embodiment, the release layer, substrate layer, and adhesive layer on the bottom film are separate structures from top to bottom, while the bottommost release layer is an integral structure.
[0010] In a further embodiment, the substrate layer is a PET film, PC film, PMMA film, or TAC film. In a further embodiment, the bottom film is divided into left and right segments along the center line.
[0011] In a further embodiment, the film has alignment handles at both ends as protrusions.
[0012] In a further embodiment, the alignment handle is located on the removal layer of the surface protective film or on the bottom film, and the alignment handle is arranged diagonally.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] The layered and segmented structure of the bottom film of this utility model allows for easy application even by untrained personnel, and achieves the technical effect of avoiding the adsorption of dust and lint from the air, resulting in no dust or air bubbles and a very high yield rate.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] like Figure 1 Figure 2As shown, this application provides a segmented screen protector, comprising a surface protective film and a bottom film arranged sequentially from top to bottom. The surface protective film includes a protective film substrate 1 and an adhesive layer 2, and the bottom film includes a release layer 3 and an adhesive layer 5. The bottom film is divided into several parts. This application divides the screen protector into a surface protective film and a bottom film, and then separates them into layers. Moreover, the bottom film is not a single structure but a separate structure, allowing the film to be applied segment by segment and then peeled off segment by segment during application.
[0021] The surface protective film has a double-layer structure, consisting of an upper removal layer and a lower actual use layer. Each layer includes a protective film substrate 1 and an adhesive layer 2 bonded together. The actual use layer is a film formed by applying anti-reflective AR treatment, anti-glare AG treatment, anti-blue light treatment, anti-peeping treatment, anti-fingerprint treatment, anti-scratch treatment, or self-healing treatment to the surface of PET film, PC film, PMMA film, or TAC film.
[0022] The bottom layer comprises, from top to bottom, a release layer 3, a substrate layer 4, and an adhesive layer 5, all stacked together. Release layer 3 can be made of silicone or non-silicone materials, the purpose being to have the same release force as the adhesive layer 2 and release layer 3 used in the actual application, facilitating film application. In one embodiment of this application, the release layer 3, substrate layer 4, and adhesive layer 5 on the bottom film are separate structures, while the bottommost release layer 3 is a single unit. This allows the bottommost release layer 3 to be peeled off completely at once, making it convenient and quick. The substrate layer 4 is a PET film, PC film, PMMA film, or TAC film. The bottom film is divided into left and right sections along the center line. During use, the release layer 3 at the bottom of the left section can be peeled off first, exposing the adhesive layer 5, which is then applied to the screen for fixation and to remove dust from the screen surface. Then, the release layer 3 on the right section is peeled off, allowing the adhesive layer 5 to remove dust from the screen surface. The adhesive layer 5 is then removed, and the substrate layer 4 is adhered and fixed to the screen. Then, the protective film removal layer is peeled off, and the actual use layer is bonded and fixed to the substrate layer 4 of the bottom film through its adhesive layer 2. The bottom film of this application can provide better alignment convenience for the actual use layer, solving the problem of poor alignment when ordinary protective films are peeled off and bonded to the screen, and the introduction of dust and air bubbles when peeled off again.
[0023] In the technical solution of this application, each end of the film is provided with an alignment handle 6 as a protrusion. The alignment handle 6 is located on the removal layer of the surface protective film or on the bottom film, and the alignment handle 6 is arranged diagonally to facilitate the user to adjust the alignment before applying the film.
[0024] In this invention, the thickness of the release layer 3 and the adhesive layer 5 is greater than that of the release layer 3 alone, which effectively improves the stiffness of the entire protection and can better improve the alignment yield. It also prevents the middle of the film material from collapsing during alignment, which would cause premature contact with the screen and affect the alignment yield.
[0025] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
