However, in the current technical context, during the assembly process of the display screen module, it is directly fixed to the PCB board and the bottom shell mask through screws. Plastic components such as the bottom shell, which are thin in thickness and large in area, are prone to deformation, and the degree of deformation is difficult to control. Therefore, after assembly, the bottom shell will deform and there will be a certain gap between it and the PCB board, and the bottom shell is prone to problems such as overall concavity or convexity. In addition, the module of the existing display screen and the box body are magnetically assembled through the magnets of the bottom shell. However, too large a deformation amount of the bottom shell will affect the magnetic attraction fixing effect between the bottom shell and the box body, and even the two cannot be effectively fixed, resulting in local shadows on the display screen, thus affecting the display effect of the display screen.
