Description

Technical Field

[0001] The utility model relates to the technical field of protective films, and more specifically, to a protective film structure. Background Art

[0002] With the continuous development of technology, touch display modules are increasingly used in various electronic devices, especially touch display modules with cameras, which not only have the function of touch interaction, but also integrate the shooting function, bringing great convenience to users' daily use. However, in the manufacturing and shipping process of touch display modules, in order to prevent the surface from being scratched or contaminated, a protective film is usually required.

[0003] In the existing technology, for touch display modules with cameras, the general method is to attach a conventional protective film with glue to other areas except the camera hole, and attach a weak glue protective film separately to the camera hole. The original intention of this design is to protect the entire module while avoiding the adverse effects of strong glue on the camera hole. However, this design has some problems in actual application. When the customer tears off the protective film during the installation process, due to the difference in the properties of the glue and the limitations of the bonding process, residual glue often appears at the camera hole. These residual glues will not only affect the aesthetics of the whole machine, but may also cause certain interference to the normal use of the camera. Therefore, we have made improvements to this and proposed a protective film structure.

[0004] For example, a Chinese patent (publication number CN216901217U) discloses a water drop screen display module, and its specification discloses: When a water drop screen mobile phone display module is shipped, it is necessary to attach a camera hole protective film to the corresponding position of the camera hole of the cover plate. Traditional protective films usually use double-sided adhesive to attach the protective film to the camera hole of the cover plate. Due to transportation, storage, defects in the design of the protective film, or defects in the adhesive material, the cover plate will have residual glue in the adhesion area, and each water drop screen mobile phone display module needs to be equipped with a camera hole protective film, which will undoubtedly increase the production and manufacturing costs of mobile phone companies, is not conducive to environmental protection, reduces the competitiveness of products, and cannot meet the growing quality requirements of manufacturers. The above patents can prove the defects of the existing technology. Utility Model Content

[0005] The technical problem to be solved by the embodiments of the present utility model is that due to the difference in the properties of glue and the limitation of the bonding process, residual glue often appears at the camera hole.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0007] A protective film structure comprises a protective film body, one side of which is provided with a protective film adhesive layer, the protective film adhesive layer is used to attach the protective film body to a cover plate, and a gap avoidance portion is provided on the protective film adhesive layer, the position of the gap avoidance portion corresponds to a camera hole position on the cover plate ink.

[0008] As an improvement of the utility model, the avoidance portion is a camera hole avoidance groove, the camera hole avoidance groove is arranged on the adhesive layer of the protective film, and the position of the camera hole avoidance groove corresponds to the camera hole position on the cover plate ink.

[0009] As an improvement of the utility model, the camera hole avoidance groove is used to isolate the protective film adhesive layer from the camera hole on the plate ink after the protective film adhesive layer is pasted on the cover plate.

[0010] As an improved manner of the utility model, an auxiliary piece is arranged between a corner of the adhesive layer of the protective film and the main body of the protective film, and the auxiliary piece is used for tearing off the main body of the protective film and the adhesive layer of the protective film.

[0011] As an improved manner of the utility model, the auxiliary component includes a notch arranged at a corner of the protective film adhesive layer, and a release paper located in the notch is fixedly connected to a side of the protective film body close to the protective film adhesive layer.

[0012] As an improved manner of the utility model, a tearing piece is provided on a side of the protective film body away from the adhesive layer of the protective film, and the tearing piece is used for tearing the protective film body and the adhesive layer of the protective film when being torn off.

[0013] As an improved manner of the utility model, the position of the tearing piece corresponds to the position of the release paper.

[0014] As an improvement of the utility model, the tearing piece is a tearing handle, one end of which is fixedly connected to the side of the protective film body away from the adhesive layer of the protective film, and the position of the tearing handle corresponds to the position of the release paper, and the other end of the tearing handle is a free end.

[0015] As an improvement of the utility model, a protrusion is provided on the side of the tear-off handle away from the protective film body, and the protrusion is used to assist the operator to pinch the free end of the tear-off handle.

[0016] As an improved manner of the utility model, the protruding piece is a handle ridge, the handle ridge is fixedly connected to a side of the tear-off handle away from the protective film body, and the handle ridge is close to the free end of the tear-off handle.

[0017] Compared with the prior art, the embodiments of the present invention mainly have the following beneficial effects:

[0018] In order to solve the problem of residual glue often appearing at the camera hole due to the difference in glue properties and the limitation of the bonding process in the prior art, the present application provides a gap on the adhesive layer of the protective film, and the position of the gap corresponds to the camera hole on the cover plate ink. That is, after the adhesive layer of the protective film is pasted on the cover plate, the adhesive layer of the protective film will not cover the camera hole of the cover plate ink, so that after the adhesive layer of the protective film and the protective film body are torn off, there will be no residual glue on the camera hole of the cover plate ink.
