Referring to fig. 13 and 14, the first and second position-limiting

portions

630 and 640 respectively include a first through hole 661 and a second through hole 662, the first through hole 661 and the second through hole 662 are communicated to form a connection channel 633, the connection channel 663 is arc-shaped, the first connection portion 621 passes through the connection channel 663 to be connected with the first bending portion 622, and the third connection portion 631 passes through the connection channel 663 to be connected with the second bending portion 632. Because the connecting channel 633 is arc-shaped, the first connecting portion 621 and the third connecting portion 631 do not form a double fold with the first bending portion 622 and the second bending portion 632 or directly contact with the 90-degree top edge of the display module 61. This can effectively prevent the first flexible circuit board 62 and the second flexible circuit board 63 from being broken.

In some embodiments, the first through hole 661 is located at a side of the display module 61 close to the first connecting portion 621 and the third connecting portion 631, and the second through hole 662 is located at the first end portion 61A. The first through holes 661 may be disposed in parallel to the non-display surface 602 of the display module 61, and the second through holes 662 may be disposed in parallel to the first end portion 61A.

In some embodiments, a gasket 664 is provided in the connecting channel 633. It should be noted that the gasket 664 can be made of a flexible material. For example, foam or silica gel is used. The material of the gasket 664 is not particularly limited in this application. The spacer 664 made of a flexible material is in contact with the first flexible circuit board 62 and the second flexible circuit board 63. Thus, even if a collision occurs, the spacer 664 has a certain cushioning property, and therefore, the first flexible circuit board 62 and the second flexible circuit board 63 are not easily broken.

Referring to fig. 15 and 16, in the present application, the display panel assembly 60 is different from the above display panel assembly 60 in that: the first position-limiting portion 630 and the second position-limiting portion 640 include an adapting portion 641 and a fastening portion 642, the adapting portion 641 is fixed on the display module 61, an outer surface of the adapting portion 641 is arc-shaped, a pressing space 643 is formed between the fastening portion 642 and the adapting portion 641, the first connecting portion 621 penetrates through the pressing space 643 to be connected with the first bending portion 622, and the third connecting portion 631 penetrates through the pressing space 643 to be connected with the second bending portion 632.

In this embodiment of the application, the first flexible circuit board 62 and the second flexible circuit board 63 are buckled and pressed on the outer surface of the adapting portion 641 through the buckling portion 642, and the outer surface of the adapting portion 641 is arc-shaped, so that the first flexible circuit board 62 and the second flexible circuit board 63 can be prevented from being broken at the bending position.

One end of the buckling portion 642 close to the first end portion 61A is rotatably connected to the adapting portion 641, and the other end thereof is connected to the adapting portion 641 in a buckling manner. That is, the position of the snap connection is located on the non-display surface 602 of the display module 61, so that the space at the top end of the display module 61 is not occupied, and the display area is not affected, because the snap-fit portion 642 is connected with the snap-fit hole of the adapting portion 641, the first flexible circuit board 62 and the second flexible circuit board 63 can be conveniently installed in the snap-fit space. Of course, one end of the engaging portion 642 near the first end portion 61A may be connected to the adapting portion 641 in a snap-fit manner, and the other end may be connected to the adapting portion 641 in a rotating manner.

In some embodiments, the width of the second notch 620 is greater than or equal to the width of the first notch 610. The height of the second notch 620 is greater than or equal to the height of the first notch 610. That is, the overall size of the second notch 620 is larger than the overall size of the first notch 610. Therefore, the first notch 610 and the second notch 620 can form an integral notch on the display screen assembly 60, and the first flexible circuit board 62 or the second flexible circuit board 63 does not obstruct the formed integral notch.

In some embodiments, the first and

second notches

610, 620 may form an integral notch in the display screen assembly 60. Functional components may be disposed within integral indentations formed in the display screen assembly 60.

In some embodiments, the optical adhesive 66 is disposed between the glass cover 65 and the touch panel 612 of the display module 61. The glass cover plate 65 is bonded to the display module 61 by an optical adhesive 66. Meanwhile, the optical adhesive 66 is transparent and does not affect the display function of the display panel 611.

In some embodiments, the display module 61 further includes a polarizer 613. The polarizer 613 is disposed on a side of the display module 61 close to the touch panel 612, that is, the polarizer 613 is disposed away from the display panel 611. The polarizer 613 is used to provide polarization to the light emitted from the display panel 611. At this time, the optical glue 66 is disposed between the polarizer 613 and the glass cover plate 65. The glass cover plate 65 is bonded to the display module 61 by an optical adhesive 66.
