AI Technical Summary
In the manufacturing process of display devices, foreign objects or contaminants may penetrate into the holes where cameras are installed, and existing technologies are unable to effectively prevent such problems.
A protective film is designed, including an attachment portion and a protrusion portion. The protrusion portion is provided with a cut portion. By providing a cut portion on the protrusion portion, physical interference is prevented from propagating to the attachment portion and the film adhesive layer, thereby preventing the protective film from peeling off from the object and reducing the adhesive force of the film adhesive layer to facilitate removal.
It effectively prevents the protective film from peeling off from the object due to physical interference, reduces the adhesive force of the film adhesive layer, making the removal of the protective film easier, and at the same time prevents foreign objects or contaminants from penetrating into the camera hole.
