Thus, by disposing the protection glue 330 at the connection of the base plate 120 and the connection portion 110 facing the display screen, since the modulus of the protection glue 330 is smaller than the glue 400 used for dispensing, the protection glue 330 is used to block the flow of the glue 400 toward the screen panel 220, so as to prevent the glue 400 from contacting the screen panel 220 and damaging the display screen 200. Before the middle frame 100 and the display screen 200 are assembled, protective glue 330 is arranged at the joint of the bottom plate 120 and the connecting part 110, after the protective glue 330 is cured, glue 400 is dispensed between the edge of the glass cover plate 210 and the connecting part 110 in a downward-pressing assembling state of the display screen 200, the glue 400 is extruded, the glue 400 overflows to two sides due to the blocking of the protective glue 330, and the protective glue 330 effectively blocks the glue 400 from flowing to the area of the screen panel 220. The screen panel 220 is prevented from being damaged by the glue 400.

In an alternative implementation, referring to fig. 16, before the middle frame 100 and the display panel 200 are assembled, a protective glue 330 is applied to the joint of the bottom plate 120 and the connecting portion 110, and a glue 400 is applied between the edge of the glass cover plate 210 and the connecting portion 110, thereby completing the assembly of the middle frame 100 and the display panel 200. Due to the blocking of the protective glue 330, the glue 400 overflows to both sides, and the protective glue 330 effectively blocks the glue 400 from flowing to the screen panel 220 area. The screen panel 220 is prevented from being damaged by the glue 400.

In the assembled state of the display panel 200, the glue 400 is squeezed, and the glue 400 overflows to both sides due to the blocking of the protection glue 330, so that the protection glue 330 effectively blocks the glue 400 from flowing to the area of the screen panel 220. The screen panel 220 is prevented from being damaged by the glue 400.
