This undoubtedly requires suppliers to reduce costs, ensure high quality, and reduce the defective rate during production. Black vinyl can help improve display effects and reduce reflections. Black vinyl can reduce backlight leakage, improve contrast and provide better display effects. It is often used in the back material of backlight sources such as LCD screens to provide a better visual experience.

[0003] However, in the process of implementing the above technical solution, it was found that there are at least the following technical problems: when a mobile phone module is defective during the manufacturing process, it needs to be returned to the warehouse for repair, and the mobile phone display module needs to be disassembled to reuse the usable part. However, the mobile phone display module is difficult to disassemble and is easily scrapped, which reduces the utilization rate of the mobile phone display module. Utility Model Content
