Of course, in other embodiments, the movable portion 12 may further be provided with a plurality of through holes 121, and the through holes 121 are circular through holes.

Referring to FIG. 17, the present application further provides a display module 200. The display module 200 includes the board 100 and a flexible display 300. The flexible display 300 is stacked on the board 100. That is, the flexible display screen 300 is stacked on the first surface 101. The flexible display 300 can be bent along with the board 100. The length and width dimensions of the flexible display screen 300 and the length and width dimensions of the board 100 may be substantially the same. When the user folds the display module 200, a portion of the flexible display screen 300 corresponding to the bendable portion 10 can be bent, that is, the display module 200 can be folded for easy carrying. The flexible display 300 may be an OLED (Organic Light-Emitting Diode) display.

It can be understood that the flexible display screen 300 may not necessarily cover the entire plate 100, but may cover only the bendable portion 10, and the flexible display screen 300 may only cover the first support. Part 20 or the second support part 30.

In one embodiment, the flexible display 300 completely covers the board 100. The flexible display screen 300 includes a first side 310 and a second side 320 disposed opposite to the first side 310, and a bendable area 330 connected between the first side 310 and the second side 320. . The first side 310 is directly opposite to the first support portion 20 and covers the first support portion 20. The second side 320 is directly opposite to the second support portion 30 and covers the second support portion 30. The bendable area 330 is directly opposite the bendable portion 10 and covers the bendable portion 10. The first side 310 and the first support portion 20 are bonded by a first adhesive layer 61. The second side 320 and the second support portion 30 are bonded by a second adhesive layer 62. The bendable region 330 and the bendable portion 10 are not fixed and can slide relative to each other. The two can be in direct contact with each other or can be separated by an air gap. When the first support portion 20 and the second support portion 30 are folded, the first side 310 and the second side 320 follow the first support portion 20 and the second support portion 30, respectively. When folded, the bendable portion 10 is deformed and bent. The flexible display screen 300 can be folded inside or outside, so that the display surface of the flexible display screen 300 can be folded inward or outward. The groove 11 of the board 10 is recessed in a direction away from the flexible display screen 300, so as to form a protrusion 17 protruding downward. When the display surface of the flexible display screen 300 is bent outward, since the flexible display screen 300 is located on the outside of the bending, it will be stretched during the bending process, and the plate 10 is located on the inside of the bending, It will be compressed during the folding process. Therefore, the first side 310 and the second side 320 of the flexible display screen 300 pull the first support portion 20 and the second support portion 30 toward each other. During the movement of the first support portion 20 and the second support portion 30 toward each other, the bendable portion 10 is compressed and deformed. Since the bendable portion 10 has a groove 11 facing away from the flexible display screen 300, the compression of the bendable portion 10 can be absorbed by the groove 11 to avoid uncontrollable wrinkles, so that The flexible display screen 300 can be flatly supported. After the groove 11 absorbs the compression of the bendable portion 10, its opening width is reduced, that is, the two movable portions 12 on two adjacent sides of the groove 11 are close to each other. The reduction of the width of the opening of the groove 11 can be more conducive to the flattening of the flexible display screen 300 after bending, and avoid the obvious visible step difference when the opening is too wide.

It should be understood that the term “relative sliding” as claimed in the present invention does not require direct contact sliding between two elements, but may relatively slide between third-party elements. Third-party components are not limited to solid components, and may also be non-solid components, such as air gaps and spaces.
