Description

Technical Field

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

[0002] With the continuous development of liquid crystal display technology, the requirements for display modules are becoming increasingly stringent. Among them, a key issue is how to reduce or avoid any unnecessary marks or defects in the display module viewing area while ensuring the display effect. However, when a smooth upper polarizer is used, since the entire surface of the protective film of the liquid crystal display module (the side close to the liquid crystal display module) has an adhesive layer, this often produces watermark-like marks in the display viewing area. These watermark marks not only affect the user's visual experience, but may also have a negative impact on the overall quality and market competitiveness of the product;

[0003] In order to solve this problem, the industry generally adopts a temporary solution: stick two protective films together, one of which has adhesive on one side, and the other has no adhesive on both sides. This method can achieve the effect of non-stickiness of the visual area protective film to a certain extent, thus avoiding the generation of watermarks. However, although this solution can temporarily solve the problem, it has significant disadvantages and shortcomings: using two protective films means more material investment, which not only increases production costs, but also does not conform to the current production concept of environmental protection and energy conservation and emission reduction. Therefore, we have made improvements on this and proposed a new type of protective film. Utility Model Content

[0004] The technical problem to be solved by the embodiment of the utility model is that the use of two protective films requires more material input, which increases the production cost.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A novel protective film comprises: a protective film body, wherein the protective film body comprises a base film layer, one side of the base film layer is provided with an adhesive portion, the adhesive portion is used to connect the base film layer with a protected object, and the adhesive portion is arranged in a frame shape.

[0007] As an improvement of the utility model, a protective piece is provided on the side of the adhesive portion away from the base film layer, and the protective piece is used for protecting the adhesive portion before bonding.

[0008] As an improved manner of the utility model, the protective member is a release film body, and the release film body is connected to a side of the adhesive portion away from the base film layer.

[0009] As an improved embodiment of the present invention, the base film layer is a protective film base film, and the protective film base film is connected to the adhesive portion.

[0010] As an improved manner of the utility model, an auxiliary part is provided on one side of the protective film base film, and the auxiliary part is used to assist in tearing off the protective film body.

[0011] As an improved manner of the utility model, the auxiliary part is a tearing handle, and the tearing handle is fixedly connected to a side of the protective film base film away from the adhesive part.

[0012] As an improved embodiment of the present invention, the adhesive portion is a first adhesive layer, which is bonded to a side of the protective film base film close to the release film body, and a side of the first adhesive layer away from the protective film base film is connected to the release film body.

[0013] As an improved embodiment of the present invention, the adhesive portion includes a second adhesive layer, which is bonded to a side of the protective film base film close to the release film body, and a side of the second adhesive layer away from the protective film base film is connected to the release film body.

[0014] As an improved manner of the utility model, a first exhaust groove is provided on the second adhesive layer, and a second exhaust groove communicating with the first exhaust groove and the outside is also provided on the second adhesive layer.

[0015] As an improved manner of the present invention, grooves are provided on the inner walls on both sides of the first exhaust groove.

[0016] Compared with the prior art, the embodiments of the present invention mainly have the following beneficial effects:

[0017] In order to solve the problem in the prior art that the use of two protective films requires more material investment and increases production costs, the present application adopts a frame-shaped adhesive layer so that the middle part of the base film layer is free of glue and only has an adhesive layer on the edge. This design not only maintains the fixing and protective effect of the protective film, but also effectively avoids the watermark problem caused by the entire surface covering of the adhesive layer; due to the design of the frame-shaped adhesive layer, the adhesive layer is only used on the edge part of the base film layer, which greatly reduces the use of the adhesive layer, thereby significantly reducing the production cost and complying with the production concept of environmental protection and energy conservation and emission reduction; since the middle part of the base film layer is free of glue, the interference of the adhesive layer on the display viewing area is avoided.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which the present invention belongs; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention. Reference to "embodiments" herein means that specific features, structures, or characteristics described in conjunction with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0026] As described in the background technology, two protective films are attached together, one of which has glue on its entire side, while the other has no glue on both sides. Through this method, the visual area protective film can achieve a non-sticky effect to a certain extent, thereby avoiding the generation of watermarks. However, although this solution can temporarily solve the problem, it brings significant disadvantages and shortcomings: using two protective films means that more material investment is required, which not only increases production costs, but also does not conform to the current production concept of environmental protection and energy conservation and emission reduction.

[0027] In order to solve this technical problem, the utility model provides a novel protective film.

[0028] Specifically, please refer to Figure 1-Figure 3 , the new protective film specifically includes:

[0029] The protective film body 1 comprises a base film layer, one side of the base film layer is provided with an adhesive portion, the adhesive portion is used to connect the base film layer with the protected object, and the adhesive portion is provided in a frame shape.

[0030] The new protective film provided by the utility model adopts a frame-shaped adhesive layer so that the middle part of the base film layer is free of glue and only has the adhesive layer on the edge part. This design not only maintains the fixing and protective function of the protective film, but also effectively avoids the problem of watermark marks caused by the entire surface covering of the adhesive layer; due to the design of the frame-shaped adhesive layer, the adhesive layer is only used on the edge part of the base film layer, which greatly reduces the use of the adhesive layer, thereby significantly reducing the production cost and complying with the production concept of environmental protection and energy saving and emission reduction; since the middle part of the base film layer is free of glue, the interference of the adhesive layer on the display viewing area is avoided.

[0031] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.
