Description

Technical Field

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

[0002] Transparent protective film is a kind of protective material widely used on various surfaces. Its main function is to protect the covered surface from scratches, stains, ultraviolet rays, etc. For example, TFT, modules, and LENS are all attached with transparent protective film for protection;

[0003] However, the transparent protective film is not easy to identify, resulting in the discovery that the protective film has not been removed until after the protected product has been assembled. The product needs to be disassembled again to remove the protective film, resulting in low efficiency.

[0004] For example, a Chinese patent (publication number: CN207159138U) discloses a protective film that prevents leakage and tearing. Its specification discloses: the fingerprint recognition module is encapsulated by a cover plate, a fingerprint recognition chip, an FPC circuit board and a metal ring wrapped around the periphery, which are stacked in sequence. The cover plate is at the top layer and directly contacts the finger. In the process of assembling and installing the fingerprint recognition module to the electronic product, it is very easy to scratch the cover plate, which affects the quality of the produced products and further affects the sales of the products. Therefore, it is necessary to attach a layer of protective film to the cover plate for protection, and the protective film needs to be torn off when the fingerprint recognition module is assembled on the product, otherwise it will affect the installation quality and accuracy of the fingerprint recognition module. However, since the protective film is transparent and the cover plate of the fingerprint recognition module also has a certain brightness, it is not convenient for the staff to distinguish between the protective film and the cover plate, so leakage and tearing often occur. The above patents can prove the defects of the prior art. Utility Model Content
