[0006] The adhesive film has an adhesive covering area, an adhesive fixing area, and a second perforation; the adhesive covering area is used to adhere to and cover the rear surface; when the adhesive covering area is adhered to the rear surface, the adhesive fixing area is located outside the edge of the protective film, the second perforation communicates with the first perforation, and the edge of the second perforation is located inside the first perforation.

[0007] Furthermore, there are multiple protected areas; each adjacent protected area has the first perforation.

[0008] Furthermore, there are multiple first hollow holes and multiple second hollow holes; the multiple first hollow holes and the multiple second hollow holes correspond one-to-one.

[0009] Furthermore, the protective film on the outer side of the protected area has positioning holes for pin insertion; when the adhesive covering area is adhered to the rear surface, the positioning holes are located on the outer side of the edge of the adhesive film.

[0010] Furthermore, the protective film has protrusions, and the positioning holes are formed on the protrusions.

[0011] Furthermore, the protective film is a one-piece piece made of polyimide.

[0012] Furthermore, the thickness of the protective film is 30 μm.

[0013] Furthermore, the adhesive film includes: a first film and a second film that are bonded together; the first film is a polyimide film and the second film is an acrylic adhesive layer.

[0014] Furthermore, the thickness of the first membrane is 35 μm, and the thickness of the second membrane is 15 μm.
