Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of protective films, and more specifically, to a porous film structure. Background Art
[0002] Existing display screen modules are mainly composed of Figure 9 As shown, it consists of a lower polarizer A, a lower glass B, an upper glass C, an upper polarizer D, adhesive E, and a cover plate F stacked in sequence. In existing blind hole project products, after the full lamination process is completed, in order to prevent light leakage from the edge of the lower polarizer opening G and affect the use of the camera, hot melt adhesive H is usually applied around the lower polarizer opening G. Subsequently, a protective film M is attached to the opening to protect the hot melt adhesive H and the polarizer opening G area;
[0003] Because protective films are often coated with an adhesive, when pressure is applied to the lower polarizer aperture G, this adhesive can transfer, partially or entirely, to the lower glass B below, creating difficult-to-remove stains. This not only affects the product's aesthetics but, more seriously, can interfere with the camera's field of view, impacting overall product performance and user experience. Therefore, we propose a porous film structure to address this issue. Utility Model Content
[0004] The technical problem to be solved by the embodiments of the present invention is that when the protective film is subjected to pressure in the opening area of the lower polarizer, this layer of adhesive may be transferred to the lower glass below, forming stains that are difficult to remove.
[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions:
[0006] A perforated film structure comprises: a protective film body and a double-sided adhesive tape, wherein the double-sided adhesive tape is attached to the protective film body, and an avoidance hole is provided on the double-sided adhesive tape, and the avoidance hole is used to avoid the opening area of the lower polarizer during attachment; in the present application, the protective film body is attached by means of the double-sided adhesive tape, and the avoidance hole is provided on the double-sided adhesive tape, and the avoidance hole is used to avoid the opening area of the lower polarizer during attachment, thereby effectively avoiding the problem of the adhesive layer of the protective film body being transferred to the lower glass surface when under pressure, thereby maintaining the cleanliness of the product and improving the overall quality of the product and user satisfaction.
[0007] As an improvement of the present invention, the double-sided adhesive has a strong side and a weak side, the strong adhesive side is attached to the protective film body, and the weak adhesive side is used to attach to the lower polarizer.
[0008] As an improvement of the present invention, the protective film body is non-adhesive.
[0009] As an improvement of the present invention, the double-sided adhesive is provided with a notch, which is used to form a ventilation channel so that air can enter the opening area of the lower polarizer to meet the requirements of hot melt adhesive curing.
[0010] As an improvement of the present invention, the shape of the notch is corner-shaped, which is used to prevent foreign matter such as dust in the air from entering the opening area of the lower polarizer. If foreign matter such as dust enters the opening area, it may affect the optical performance of the product or cause other problems. On the other hand, the design of the corner-shaped notch is relatively complex, which can increase the difficulty of foreign matter entering and improve the protection effect. The reason is that the corner-shaped notch can play a certain blocking role on foreign matter such as dust, reducing the impact of external impurities on the product.
[0011] As an improvement of the present invention, the area of the double-sided adhesive is smaller than the area of the protective film body.
[0012] As an improvement of the present invention, the protective film body has a tearing handle located on the double-sided adhesive side. After attachment, there is a gap between the protective film body and the lower polarizer, which makes it easy to tear off the protective film body.
[0013] As an improvement of the present invention, the protective film body is made of transparent plastic, has good wear resistance and scratch resistance, and is convenient for alignment during bonding. The tearing hand position provides the user with a clear fulcrum, making it easier to operate when the protective film body and double-sided adhesive need to be torn off. The existence of the gap creates a certain space between the protective film body and the lower polarizer, which is convenient for grasping the tearing hand position when tearing off. This design can reduce the risk of damage to the product during the tearing process, and also improves the efficiency of the operation.
[0014] As an improvement of the present invention, one end of the protective film body is arranged in an arc shape, and the arc-shaped end of the protective film body is close to the double-sided adhesive.
[0015] As an improvement of the present invention, an antistatic coating is provided on the outer surface of the protective film body.
[0016] Compared with the prior art, the embodiments of the present invention have the following beneficial effects:
[0017] In order to solve the problem in the prior art that when the protective film is subjected to pressure in the opening area of the lower polarizer, this layer of adhesive may be transferred to the lower glass below, forming stains that are difficult to remove, the protective film body in this application is pasted by double-sided adhesive, and avoidance holes are opened on the double-sided adhesive. The avoidance holes are used to avoid the opening area of the lower polarizer when attached, effectively avoiding the problem of the adhesive layer of the protective film body being transferred to the lower glass surface when under pressure, maintaining the cleanliness of the product, and improving the overall quality of the product and user satisfaction.

It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0030] As described in the background technology, the surface of the protective film is often coated with a layer of adhesive. When the protective film is subjected to pressure in the opening area of the lower polarizer, this layer of adhesive may be transferred, that is, part or all of the adhesive will be transferred to the lower glass below, forming stains that are difficult to remove. This stain not only affects the appearance of the product, but more seriously, it may interfere with the normal field of view of the camera, thereby affecting the overall performance of the product and user experience.
[0031] In order to solve this technical problem, the utility model provides a porous membrane structure.
[0032] Specifically, please refer to Figures 1-4 , the pore membrane structure specifically includes:
[0033] The protective film body 1 and the double-sided adhesive 2 are attached to the protective film body 1. The double-sided adhesive 2 is provided with an avoidance hole 201, which is used to avoid the opening area of the lower polarizer during attachment.
[0034] The utility model provides a porous film structure. In this application, the protective film body 1 is pasted by double-sided adhesive 2, and an avoidance hole 201 is opened on the double-sided adhesive 2. The avoidance hole 201 is used to avoid the opening area of the lower polarizer when attaching, effectively avoiding the problem of the adhesive layer of the protective film body 1 being transferred to the lower glass surface when under pressure, maintaining the cleanliness of the product, and improving the overall quality of the product and user satisfaction.
[0035] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0036] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.
[0037] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.
[0038] Example 1 of the porous membrane structure of the utility model
[0039] Please refer to Figures 1-4The utility model has a porous film structure. It includes: a protective film body 1 and a double-sided adhesive 2, the double-sided adhesive 2 is attached to the protective film body 1, and a avoidance hole 201 is opened on the double-sided adhesive 2, and the avoidance hole 201 is used to avoid the opening area of the lower polarizer when attached; in this application, the protective film body 1 is attached by the double-sided adhesive 2, and the avoidance hole 201 is opened on the double-sided adhesive 2, and the avoidance hole 201 is used to avoid the opening area of the lower polarizer when attached, which effectively avoids the problem of the adhesive layer of the protective film body 1 being transferred to the lower glass surface when under pressure, maintains the cleanliness of the product, and improves the overall quality of the product and user satisfaction;
[0040] This design can effectively avoid the problem of the protective film body 1 being transferred to the lower glass surface by the double-sided adhesive 2 when it is under pressure. On the one hand, it maintains the cleanliness of the product, making the product more beautiful and neat in appearance, and will not cause stains or unevenness due to the double-sided adhesive 2 transfer. On the other hand, it improves the overall quality of the product and reduces the problem of product performance degradation that may be caused by the double-sided adhesive 2 transfer. At the same time, it also improves user satisfaction. Users will not be troubled by the double-sided adhesive 2 transfer when using the product and can get a better use experience.
[0041] Furthermore, the double-sided adhesive 2 has two strong and weak sides, the strongly sticky side is attached to the protective film body 1, and the weakly sticky side is used to attach to the lower polarizer; this design can better fix the protective film body 1, ensuring that the protective film body 1 will not fall off easily during use. At the same time, the weakly sticky side is used to attach to the lower polarizer, making it easier to tear off from the lower polarizer when needed without leaving residual glue that is difficult to clean, thereby facilitating product replacement and maintenance. This not only ensures the stability of the protective film, but also improves the convenience of use.
[0042] Furthermore, the protective film body 1 is non-adhesive; the non-adhesive setting of the protective film body 1 brings many benefits. First, it avoids unnecessary adhesion between the protective film body 1 and other components, reducing the trouble caused by accidental adhesion. Secondly, the non-adhesive protective film body 1 is more convenient during storage and transportation, and will not stick to other items, reducing the risk of damage. Finally, the non-adhesive setting also makes it possible to more flexibly adjust the position of the protective film body 1 during use, thereby improving the convenience of operation.
[0043] Example 2 of the utility model porous membrane structure
[0044] The utility model has a further porous membrane structure, such as Figure 4As shown, a notch 202 is provided on the double-sided adhesive 2, and the notch 202 is used to form a ventilation channel so that air can enter the opening area of the lower polarizer to meet the curing requirements of the hot melt adhesive. The provision of the notch 202 to form a ventilation channel is of great significance. First, it ensures that the hot melt adhesive can be cured smoothly, so that the various components of the product can be firmly combined together, thereby improving the stability and reliability of the product. Secondly, the existence of the ventilation channel helps to discharge possible gases, avoid defects such as bubbles during the curing process, and further improve the quality of the product.
[0045] Further, such as Figure 4 As shown, the shape of the notch 202 is a corner shape, which is used to prevent foreign matter such as dust in the air from entering the opening area of the lower polarizer, thereby maintaining the cleanliness and performance of the product. If foreign matter such as dust enters the opening area, it may affect the optical performance of the product or cause other problems. On the other hand, the design of the corner notch 202 is relatively complex, which can increase the difficulty of foreign matter entering and improve the protection effect. The reason is that the corner notch 202 can play a certain blocking role on foreign matter such as dust, thereby reducing the impact of external impurities on the product.
[0046] Further, such as Figure 1 and Figure 4 As shown, the area of the double-sided adhesive 2 is smaller than the area of the protective film body 1; this arrangement can ensure the adhesive effect while reducing the adverse effects that may be caused by the double-sided adhesive 2, such as residual glue and other problems. The double-sided adhesive 2 with a smaller area is easier to clean when torn off and will not leave excessive residue on the product surface.
[0047] Further, such as Figure 1 and Figure 4 As shown, the protective film body 1 has a tearing handle located on the side where the double-sided adhesive 2 is attached. The tearing handle is the area on the protective film body 1 where the double-sided adhesive 2 is not attached, so that there is a gap between the protective film body 1 and the lower polarizer after attachment, which is convenient for tearing off the protective film body 1; the design of the tearing handle and the gap greatly improves the convenience of use. The tearing handle provides the user with a clear fulcrum, making it easier to operate when the protective film body 1 and the double-sided adhesive 2 need to be torn off, and the existence of the gap allows a certain space between the protective film body 1 and the lower polarizer, which is convenient for grasping the tearing handle when tearing. Such a design can reduce the risk of damage to the product during the tearing process, and also improves the efficiency of the operation.
[0048] Example 3 of the utility model porous membrane structure
[0049] The porous membrane structure of the present invention is further improved, and the protective film body 1 is made of transparent plastic; using transparent plastic to make the protective film body 1 has many advantages. First, the good wear resistance and scratch resistance can effectively protect the product surface and reduce scratches and damage caused by friction or collision during use; secondly, the transparent property makes it possible to clearly see the protected parts during bonding, which facilitates alignment operations and improves production efficiency and product quality. At the same time, the transparent protective film body 1 will not affect the appearance and optical properties of the product, maintaining the beauty and practicality of the product.
[0050] Furthermore, one end of the protective film body 1 is set in an arc shape, and the arc end of the protective film body 1 is close to the double-sided adhesive 2. The design of the arc end has many advantages. First, the arc end is relatively smooth and is not easily damaged by external force during use, which improves the durability of the protective film body. Secondly, the arc design is more beautiful and soft in appearance, and is more coordinated with the overall shape of the product. In addition, the position design of the arc end close to the double-sided adhesive 2 also makes the fitting process smoother, reducing the problem of loose fitting caused by sharp edges; finally, the arc setting also makes it easy to distinguish the position where the double-sided adhesive 2 is set on the protective film body 1.
[0051] Furthermore, the outer surface of the protective film body 1 is provided with an antistatic coating. The antistatic coating can effectively prevent static electricity from damaging the product, avoid problems such as sparks or dust adsorption caused by static electricity, and improve the safety and reliability of the product. Secondly, the antistatic coating can reduce the accumulation of static electricity, making the protective film body 1 more stable during use and will not affect the performance of the product due to static electricity interference. The reason is that the antistatic coating can reduce the generation and accumulation of static electricity, and avoid static electricity from damaging the electronic components inside the product; the antistatic coating is usually composed of materials with conductive or antistatic properties. Common antistatic coating materials include conductive polymers, metal oxides, carbon nanotubes, etc.
[0052] Obviously, the embodiments described above are only some of the embodiments of the present invention, rather than all of the embodiments. The preferred embodiments of the present invention are given in the accompanying drawings, but they do not limit the patent scope of the present invention. The present invention can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.
