Description

Technical Field

[0001] The utility model relates to the technical field of tempered films, in particular to a tempered film for a micro-curved screen with edge elastic attachment. Background Technique

[0002] With the gradual development of mobile phone screens, in order to bring a better user experience, some mobile phone screens are set to a micro-curved screen structure with slight bending on all four sides. When using a mobile phone screen with this structure, it can produce a better three-dimensional visual effect of the picture and bring a better touch experience to the user. However, using a mobile phone with such a micro-curved screen will cause some tempered films to not fully adhere to the mobile phone screen. The main reason is that there is a certain error due to the micro-curve between the edge of the tempered film and the screen, resulting in the edge not being fully adhered, or the middle not being fully adhered after the edge is fully adhered, causing bubbles to appear between the screen and the tempered film. To solve this problem, the prior art proposes to only set an adhesive border on the edge of the tempered film and attach only the edge of the tempered film to the mobile phone screen. This attachment method prevents local bubbles from occurring between the mobile phone screen and the tempered film. However, due to the setting of the adhesive border at the edge, the adhesive border will present a certain supporting effect, resulting in a certain supporting gap at the inner position corresponding to the adhesive border between the screen and the tempered film, causing the situation of insensitive clicking at this position. Therefore, after attaching this tempered film, it is generally required to press hard back and forth around the edge of the tempered film for a certain period of time to increase the touch sensitivity to make up for the defects of this tempered film. In view of this problem, it is necessary to propose an improved technical solution. Summary of the Utility Model

[0003] The utility model aims to provide a technical solution to solve the above problems in order to overcome the above situations.

[0004] A tempered film for a micro-curved screen with edge elastic attachment includes a tempered film main body, an elastic border, and an adhesive border. The periphery of the tempered film main body is a downwardly curved surface structure, and a ring groove portion is provided at the edge position of the lower end surface of the tempered film main body. The elastic border is arranged in the ring groove portion, and the adhesive border is attached to the lower end of the elastic border.

[0005] Preferably, the tempered film main body includes a tempered layer, an optical adhesive layer attached to the lower end surface of the tempered layer, and an explosion-proof film layer attached to the lower end surface of the optical adhesive layer. The optical adhesive layer and the explosion-proof film layer are spaced apart from the edge of the tempered layer, so that the ring groove portion is formed after the tempered film main body is formed by the bonding of the optical adhesive layer, the explosion-proof film layer, and the tempered layer.

[0006] Preferably, the elastic border is made of a colored rubber material.

[0007] Preferably, the adhesive border is made of double-sided tape material, and both the adhesive border and the elastic border are in clearance fit with the optical adhesive layer and the explosion-proof film layer.

[0008] Preferably, the sum of the thicknesses of the optical adhesive layer and the explosion-proof film layer is equal to or greater than the thickness of the elastic border, and the sum of the thicknesses of the optical adhesive layer and the explosion-proof film layer is less than the sum of the thicknesses of the elastic border and the adhesive border.

[0009] Preferably, the explosion-proof film layer is made of PET material.

[0010] Preferably, dot matrix silicone layers are arranged in an array at the lower end of the explosion-proof film layer.

[0011] Preferably, an anti-blue light layer is coated on the lower end face of the tempered layer.

[0012] Preferably, an anti-fingerprint layer is coated on the upper end face of the tempered layer.

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

[0014] By arranging the elastic border in the annular groove portion, it can play a buffering and self-adaptive role during the attachment process, further ensuring a perfect fit between the tempered film and the edge of the mobile phone screen. Any changes in the curvature of the tempered film body after tempering can be self-adaptively adjusted by the elastic border, thus achieving an all-round fit.

[0015] The adhesive border is attached to the lower end of the elastic border. This design ensures firm attachment at the edge while the elastic border can effectively avoid the support gap caused by the supporting effect of the adhesive border. Compared with the prior art, it greatly reduces the probability of unresponsive clicking at the position corresponding to the inner side of the adhesive border between the screen and the tempered film. That is, when a user uses a mobile phone with such a tempered film attached, there is no need to press hard around the edge of the tempered film for a certain period of time after attachment to increase touch sensitivity as in the case of using a traditional tempered film for a micro-curved screen. This saves the user's time and energy, improves the convenience of use, and the touch effect after attachment is better.

[0016] The setting of the elastic border can also absorb the impact and vibration received by the mobile phone during use to a certain extent, play a better protective role for the mobile phone screen, and extend the service life of the mobile phone screen.

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0027] Please refer to Figures 1-5, in the embodiment of the present utility model, a tempered glass film for a micro-curved screen with edge elastic attachment is proposed, which includes a tempered glass film main body 10, an elastic frame 20 and an adhesive frame 30. The periphery of the tempered glass film main body 10 is a downwardly curved surface structure, and a ring groove portion 11 is provided at the edge position of the lower end surface of the tempered glass film main body 10. The elastic frame 20 is arranged in the ring groove portion 11, and the adhesive frame 30 is attached to the lower end of the elastic frame 20. By arranging the elastic frame 20 in the ring groove portion 11, it can play a buffering and adaptive role during the attachment process, further ensuring the perfect fit between the tempered glass film and the edge of the mobile phone screen. Any changes in the curvature of the tempered glass film main body 10 after tempering can be adaptively adjusted by the elastic frame 20, so as to achieve an all-round fit. Moreover, since the adhesive frame 30 is attached to the lower end of the elastic frame 20, this design ensures firm attachment at the edge while the elastic frame 20 can effectively avoid the support gap caused by the support of the adhesive frame 30. Compared with the prior art, the probability of the situation where the click is insensitive at the inner position of the adhesive frame 30 corresponding to the screen and the tempered glass film is greatly reduced. That is, when a user uses a mobile phone with such a tempered glass film attached, there is no need to press hard around the edge of the tempered glass film back and forth for a certain time after attachment to increase the touch sensitivity as in the case of using a traditional micro-curved screen tempered glass film, saving the user's time and energy, improving the convenience of use, and having a better touch effect after attachment. In addition, the setting of the elastic frame 20 can also absorb the impact and vibration received by the mobile phone during use to a certain extent, play a better protective role for the mobile phone screen, and extend the service life of the mobile phone screen.

[0028] Please refer to Figure 1 , in the embodiment of the present utility model, it is further proposed that the tempered glass film main body 10 includes a tempered layer 12, an optical adhesive layer 13 attached to the lower end surface of the tempered layer 12, and an explosion-proof film layer 14 attached to the lower end surface of the optical adhesive layer 13. Both the optical adhesive layer 13 and the explosion-proof film layer 14 are spaced apart from the edge of the tempered layer 12, so that the ring groove portion 11 is formed after the tempered glass film main body 10 is formed by the lamination of the optical adhesive layer 13, the explosion-proof film layer 14 and the tempered layer 12. The explosion-proof film layer 14 plays a key role when the mobile phone is severely impacted, reducing the risk of injury to the user caused by the flying fragments after the screen is broken. The optical adhesive layer 13 ensures the firm bonding between the layers and does not affect the display effect of the screen at the same time. The ring groove portion 11 formed by setting the optical adhesive layer 13 and the explosion-proof film layer 14 to be spaced apart from the edge of the tempered layer 12 provides an accurate position for the installation of the elastic frame 20, and the elastic frame 20 can better adapt to the shape of the micro-curved screen, making the fit between the tempered glass film and the mobile phone screen closer.

[0029] Please refer to Figure 3, in the embodiments of the present utility model, it is further proposed that the elastic frame 20 is made of a colored rubber material; the adhesive frame 30 is made of a double-sided adhesive material, and both the adhesive frame 30 and the elastic frame 20 are in clearance fit with the optical adhesive layer 13 and the explosion-proof film layer 14; the elastic frame 20 made of rubber material can give full play to its elastic advantages, better adapt to various curvature changes of the micro-curved screen, ensure the close fit between the tempered film and the edge of the mobile phone screen, effectively reduce the generation of bubbles, and improve the quality and stability of the fit; moreover, the colored rubber elastic frame 20 adds a unique appearance feature to the tempered film, and different colors can be selected according to the preferences of users to meet personalized needs. At the same time, the colored frame also makes the tempered film more eye-catching on the mobile phone, enhancing the overall aesthetics of the mobile phone; the adhesive frame 30 made of double-sided adhesive material can provide reliable adhesion, firmly fix the tempered film on the mobile phone screen and is not easy to fall off, providing continuous protection for the mobile phone screen.

[0030] Please refer to Figure 3 , in the embodiments of the present utility model, it is further proposed that the sum of the thicknesses of the optical adhesive layer 13 and the explosion-proof film layer 14 is equal to or greater than the thickness of the elastic frame 20, and the sum of the thicknesses of the optical adhesive layer 13 and the explosion-proof film layer 14 is less than the sum of the thicknesses of the elastic frame 20 and the adhesive frame 30; when attaching the tempered film to the mobile phone screen, the combined thickness of the optical adhesive layer 13 and the explosion-proof film layer 14 matches the thickness of the elastic frame 20, which can ensure that the main body 10 of the tempered film and the elastic frame 20 are more coordinated in the overall structure. When attached to the mobile phone screen, since the sum of the thicknesses of the optical adhesive layer 13 and the explosion-proof film layer 14 is equal to or greater than the thickness of the elastic frame 20, at the part where the elastic frame 20 contacts the edge of the mobile phone screen, the optical adhesive layer 13 and the explosion-proof film layer 14 can provide certain support to prevent the elastic frame 20 from being overly compressed and affecting its elastic performance. At the same time, the sum of the thicknesses of the optical adhesive layer 13 and the explosion-proof film layer 14 is less than the sum of the thicknesses of the elastic frame 20 and the adhesive frame 30. In this way, during the attachment process, the adhesive frame 30 can better contact the mobile phone screen and generate a firm adhesion force. When the adhesive frame 30 is attached to the mobile phone screen, the elastic frame 20 is compressed to a certain extent, while the optical adhesive layer 13 and the explosion-proof film layer 14 are in close contact with the mobile phone screen under the support of the elastic frame 20, ensuring the stability and fit of the entire tempered film. Through this setting, the reasonable thickness relationship enables the tempered film to better adapt to the shape of the screen when attached to the micro-curved screen mobile phone. The thicknesses of the optical adhesive layer 13 and the explosion-proof film layer 14 match the thickness of the elastic frame 20, ensuring that all parts can work together during the attachment process, improving the accuracy and stability of the attachment, and avoiding problems such as loose attachment caused by mismatched thicknesses.

[0031] Please refer to Figure 1 , Figure 3 and Figure 5, in the embodiments of the present utility model, it is further proposed that the explosion-proof film layer 14 is made of PET material; a dot matrix silica gel layer 15 is arranged in an array at the lower end of the explosion-proof film layer 14; an anti-blue light layer 16 is coated on the lower end surface of the tempered layer 12; an anti-fingerprint layer 17 is coated on the upper end surface of the tempered layer 12. The explosion-proof film layer 14 is made of PET material, which has good toughness, transparency and chemical resistance. When the mobile phone is impacted by external force, the PET explosion-proof film layer 14 can absorb and disperse the impact force to prevent the mobile phone screen from cracking. At the same time, the high transparency of the PET material ensures that the display effect of the mobile phone screen is not affected; a dot matrix silica gel layer 15 is arranged in an array at the lower end of the explosion-proof film layer 14. The dot matrix silica gel layer 15 is composed of many tiny silica gel particles. When these particles are attached to the mobile phone screen, they can form tiny gaps with the screen surface, thus avoiding the bubble problem that may occur during complete adhesion. At the same time, the dot matrix silica gel layer 15 can also increase the friction between the explosion-proof film layer 14 and the mobile phone screen, improve the stability of the tempered film, and prevent sliding during use; the anti-blue light layer 16 is usually composed of materials that can absorb or reflect blue light of specific wavelengths. When the light emitted by the mobile phone screen passes through the tempered layer 12 and reaches the anti-blue light layer 16, the substances in the anti-blue light layer 16 will selectively absorb or reflect the blue light, reducing the amount of blue light entering the human eye; the anti-fingerprint layer 17 is generally a low surface energy coating with a special micro-structure on its surface. When a finger touches the upper end surface of the tempered layer 12, the special structure of the anti-fingerprint layer 17 makes it difficult for fingerprints, oils and other stains to adhere to its surface.

[0032] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims in the present utility model.
