Description

TECHNICAL FIELD

[0001] The application relates to the technical field of film pasting, in particular to a protective film facilitating optical performance detection of a camera hole of a display screen and a pasted protective film. BACKGROUND

[0002] In existing display screen products, a protective film usually covers the entire display area to protect the screen from physical damage. However, the camera hole area, as the entrance and exit of the camera, is crucial to the optical performance of the product and needs to be kept clean and free of interference. When performing optical tests, the traditional protective film needs to be torn up and then re-covered. Both methods have certain problems. First, when re-covering the protective film, dust, bubbles and other foreign matters are often brought into the vicinity of the camera, affecting the accuracy of the test results. Second, the step of tearing up the complete protective film and then covering it takes a long time, affecting work efficiency. CONTENT OF THE UTILITY MODEL

[0003] The technical problem to be solved by the application is that only the camera hole area protective film needs to be lifted, without tearing up the entire protective film. This avoids excessive bubbles and dust foreign matters entering the protective film after re-covering the protective film.

[0004] To solve the above technical problem, the application provides a protective film facilitating optical performance detection of a camera hole of a display screen and a pasted protective film, which adopts the technical scheme as follows:

[0005] The protective film comprises a main body protective film and a camera hole area protective film.

[0006] The outer edge of the camera hole area protective film is connected to the top outer edge of the main body protective film, and the main body protective film and the camera hole area protective film are integrally formed by half-punching.

[0007] Further, an easy-to-tear handle is arranged at one end corner of the main body protective film. The easy-to-tear handle is arranged at the outer edge of the main body protective film, and the easy-to-tear handle and the main body protective film are integrally formed by punching.

[0008] Further, the easy-to-tear handle is located at the right end corner directly above the main body protective film. The easy-to-tear handle and the main body protective film are press-formed with a folding indentation strip, and the right side edge of the easy-to-tear handle is flush with the right side edge of the main body protective film.

[0009] Further, the part of the camera hole area protective film extending downward in the middle is a water drop area.

[0010] Further, the bottom surface of the main protection film and the bottom surface of the camera hole area protection film are adhered to the surface of the part to be protected through a glue layer.

[0011] Further, the end of the camera hole area protection film extending outward is a pull end, and the pull end and the camera hole area protection film are integrated structures.

[0012] Further, the protection film facilitating optical performance detection of a camera hole of a display screen further comprises a display module, and the overall length and width dimensions of the main protection film and the camera hole area protection film are greater than the length and width dimensions of the display module.

[0013] Further, the material of the main protection film and the camera hole area protection film is PET material.

[0014] Further, the glue layer is a transparent glue layer.

[0015] The utility model embodiment further provides a protective film, which comprises a release film and one or more protective films facilitating optical performance detection of a camera hole of a display screen attached to the release film.

[0016] Compared with the prior art, the embodiment of the application has the following beneficial effects:

[0017] The camera hole area protection film is separated from the main protection film in a half-punching mode, and the independent camera hole area protection film and the main protection film are formed. The camera hole area protection film protects the camera hole area of the display screen product and avoids pollution or damage during the test. The main protection film protects the main part of the display screen and ensures the safety of the whole screen. When optical testing of the camera hole area of the display screen product is required, the camera hole area protection film only needs to be lifted, and the whole protective film does not need to be torn, which can effectively avoid the entry of bubbles, dust and other foreign matters when the protective film is re-covered, thereby improving the accuracy of optical testing and the reliability of test results.
