[0006] The design of the bent flexible circuit board is conducive to reducing the binding size of the flexible circuit board and the display panel in the length direction, and is conducive to reducing the size of the flexible circuit board in the length direction of the display module, which is conducive to improving the space utilization of the flexible circuit board and the display panel, and is conducive to improving the space utilization of the display module, thereby facilitating the increase of the space that the battery can occupy in the length direction of the electronic device (i.e., the length direction of the display module), and is conducive to increasing the volume and capacity of the battery.

[0008] In this way, the extending section and the bending section of the bending portion can be supported by the fixing body to improve the strength of the bending portion of the flexible circuit board, which is beneficial to improving the structural stability of the flexible circuit board and further beneficial to improving the structural stability of the circuit board assembly.

[0009] In one possible embodiment, the main body includes a connecting end face, the extension section is connected to the connecting end face, the bending section includes a mating area, and the first mating portion includes an installation area. In the thickness direction of the display module, the mating area and the installation area are fixedly stacked and electrically connected to form a binding area; in the thickness direction of the display module, the projection of the connecting end face is located in the binding area; or, in the thickness direction of the display module, the projection of the connecting end face is located in the bending section and is spaced from the installation area and the mating area.

[0010] This is beneficial to increasing the width dimension of the main body (the dimension in the X-axis direction), which is beneficial to increasing the wiring space of the main body, thereby reducing the thickness dimension of the main body (the dimension in the Z-axis direction), reducing the thickness dimension of the display module, and facilitating the miniaturization design of the display module.

[0011] In a possible implementation, the mating region includes a mating end surface, the mounting region includes a mounting end surface, and in the second direction, the connecting end surface is located between the mating end surface and the mounting end surface, and the second direction is perpendicular to the thickness direction of the display module.

[0012] Since the connecting end face is located between the mating end face and the mounting end face, the projection of the connecting end face in the thickness direction of the display module is located in the binding area, which is beneficial to increase the width dimension of the main body (the dimension in the X-axis direction), and is beneficial to increase the wiring space of the main body, thereby facilitating the reduction of the thickness dimension of the main body (the dimension in the Z-axis direction), and is beneficial to reducing the thickness dimension of the display module, which is beneficial to the miniaturized design of the display module.

Moreover, in the second direction, the vertex is located on one side of the assembly end surface of the main body and the connection surface of the support body, and the design that the distance between the vertex and the assembly end surface of the main body is less than or equal to the distance between the vertex and the connection surface of the support body ensures that the support body and the main body have a large contact area, which is beneficial to improving the support of the main body by the support body, and is beneficial to improving the support effect of the support body on the flexible circuit board, and is beneficial to improving the connection stability of the flexible circuit board and the display panel, and further to improving the structural stability of the display module; moreover, it is beneficial to improve the space utilization rate of the flexible circuit board, the display panel and the support body, and further to improve the space utilization rate of the display module, and is beneficial to the miniaturization design of the display module.

[0026] In this way, since the assembly end face of the main body is flush with the connecting surface of the support body, the distance between the vertex and the assembly end face of the main body is equal to the distance between the vertex and the connecting surface of the support body, it is beneficial to increase the contact area between the support body and the main body, further improve the supporting effect of the support body on the flexible circuit board, and then help to improve the structural stability of the display module.

[0029] In one possible embodiment, the display panel includes a display portion, which is located on a side of the first mating portion facing away from the mounting surface and is opposite to and spaced apart from the first mating portion, and the display portion is located on a side of the second mating portion facing toward the first mating portion and is fixedly and electrically connected to the second mating portion, and in the thickness direction of the display module, the display portion is located on a side of the first mating portion facing away from the flexible circuit board.

[0030] The display panel is fixedly and electrically connected to the flexible circuit board through the first matching portion, and the image is displayed through the display portion.

[0037] In a possible implementation manner, the avoidance hole is a blind hole or a through hole.

[0038] It can be understood that the avoidance hole can penetrate the main body of the flexible circuit board (that is, the avoidance hole is a through hole), or it can not penetrate the main body of the flexible circuit board (that is, the avoidance hole is a blind hole). The setting of the avoidance hole can be set according to the thickness dimension of the main body (the dimension in the Z-axis direction) to ensure the structural stability of the main body.

[0248] and Fig.29 Compared with the electronic device 100 shown in the figure, the electronic device 100 and the display module 30 shown in this embodiment, by setting an avoidance hole 84a on the main body 82 of the flexible circuit board 81, the design of partially accommodating the driving chip 51 in the avoidance hole 84a is beneficial to reducing the distance between the main body 82 and the driving chip 51, which is beneficial to improving the space utilization of the display module 30, and is beneficial to reducing the thickness dimension of the display module 30 (the dimension in the Z-axis direction), which is beneficial to reducing the thickness dimension of the electronic device 100 (the dimension in the Z-axis direction), and further conducive to the miniaturization design of the display module 30 and the electronic device 100.
