Description

Technical Field

[0001] The utility model relates to the technical field of tempered films, in particular to a curved screen privacy protection tempered film. Background Art

[0002] With the gradual upgrading of smartphone designs, some existing smartphone screens have introduced curved screen structural designs, and the front camera of the smartphone is integrated into the screen, which can improve the sensory experience, make the large screen more resistant to falling, and have a better three-dimensional display effect. However, in order to better protect the screen of traditional smartphones during use and prevent the outermost layer of the screen from being scratched after long-term use and cannot be replaced, it has become a traditional technology to attach a tempered film to the screen of the smartphone as protection. However, since the design of the curved screen is different from that of the traditional straight screen, the use of a traditional tempered film to attach the curved screen will not be able to fully cover the curved screen. If the curved screen is designed relying on the structural design of the traditional tempered film, there will be a situation where the adhesive layer is not attached in place. Therefore, the prior art introduces a UV curved tempered film, which separates the glue attached to the curved tempered film from the curved tempered film, and uses UV light curing to solidify the glue, thereby achieving the purpose of attaching the curved tempered film in all directions;

[0003] In addition, in order to achieve the anti-peeping effect, the UV curved tempered film also introduces an anti-peeping grating structure. However, the introduction of the anti-peeping grating structure is bound to affect the photo clarity of the front lens. Therefore, when designing a UV curved tempered film with an anti-peeping effect, the UV curved tempered film is located at the position of the front lens and is set to a hollow structure. With the setting of this type of structure, during the UV glue bonding operation, part of the UV glue will always overflow to the position of the front lens. If it is cleaned later, there will often be more residues. The UV glue itself also has a certain viscosity after curing, and it is easy to accumulate dust layers, so it is easy to affect the cleanliness of the mirror surface. A fingerprint unlocking area is set on the screen of some smart phones, and the setting of the anti-peeping structure will also affect the recognition of fingerprints in the fingerprint unlocking area. In comparison, it is necessary to propose an improved technical solution to solve the above problems. Utility Model Content

Through this arrangement, the curved screen anti-peep tempered film can be The invention is arranged on the screen of a smart phone integrated with a front lens and a fingerprint unlocking function, and will not affect the front lens and the fingerprint unlocking function, and can control the UV glue during the film pasting process, thereby eliminating the step of processing the UV glue remaining at the position of the front lens after baking the glue, so that the film pasting efficiency is higher, and the second hollow hole 16 at the position of the fingerprint unlocking area is filled with UV glue at a later stage, so that the step of filling the second hollow hole 16 is eliminated during the production and processing of the curved screen anti-peeping tempered film, thereby improving the production efficiency of the curved screen anti-peeping tempered film.
