In the embodiment shown in fig. 2, the middle frame 200 is substantially rectangular and includes a frame body 210 and an adhesive layer 220, the adhesive layer 220 is disposed on one side of the frame body 210, and the adhesive layer 220 is used for fixedly connecting the display module 100 to the middle frame 200. In some embodiments, the adhesive layer 220 is a double-sided adhesive tape, which can reliably mount the display module 100 on the frame 210. In other embodiments, the adhesive layer 220 may be formed by a dispensing process, and the adhesive layer 220 can also reliably mount the display module 100 on the frame 210. The frame body 210 is provided with a through hole 201, and the through hole 201 penetrates through two opposite sides of the frame body 210. The adhesive layer 220 is provided with a drainage groove 221 communicated with the through hole 201, and the drainage groove 221 extends to the surface of the adhesive layer 220 at one side of the adhesive layer 220 facing the display screen module 100. In some embodiments, the drainage channels 221 are elongated strips having a width of 0.6mm to 2 mm.
