Referring to fig. 3 to 9, the display screen assembly 60 includes a display module 61, a first flexible circuit board 62 and a second flexible circuit board 63.

The display module 61 has a display surface 601 and a non-display surface 602, which are oppositely disposed, the display surface 601 is used for displaying, and the display surface 601 faces the outside of the display screen assembly 60. The non-display surface 602 is not displayed and the non-display surface 602 is located inside the display screen assembly 60. The display module 61 has a first end portion 61A, wherein the first end portion 61A is a top end of the display module 61 when displaying information, and the first end portion 61A can refer to the description of the top end 10A of the display screen 10.

Referring to fig. 6, the display module 61 may include a display panel 611 and a touch panel 612 disposed on the display panel 611. The display panel 611 is used to implement a display function of the electronic apparatus 100 to display information such as images and text. The display panel 611 includes opposing first and

second surfaces

6111, 6112. After the electronic device 100 is installed, the first surface 6111 is hidden inside the electronic device 100, and the second surface 6112 faces the user.

The touch panel 612 is used for implementing a touch function of the electronic device 100, so that a user can implement control over the electronic device 100 by pressing the touch panel 612. The touch panel 612 includes a third surface 6121 and a fourth surface 6122 opposite to each other. After the electronic device 100 is installed, the third surface 6121 is hidden inside the electronic device 100, and the fourth surface 6122 faces the user. The fourth surface 6122 is a pressing surface when the user performs a touch operation. The second surface 6112 of the display panel 611 contacts with the third surface 6121 of the touch panel 612. The end of the display panel 611 is higher than the touch panel 612, or the display panel 611 is closer to the first end 61A than the touch panel 612.

In some embodiments, the first flexible circuit board 62 is disposed on the non-display surface 602 of the display module 61, and the first flexible circuit board 62 is located at the first end portion 61A of the display module 61. The first flexible circuit board 62 may extend from the non-display surface 602 to the inside of the display module 61 by bypassing the first end portion 61A, and be electrically connected to the display panel 611, so as to drive the display module 61 to implement the display function. The first flexible circuit board 62 is electrically connected to the circuit board 30. Thus, a control signal generated by a processor of the electronic device 100 may be transmitted to the display panel 611 through the first flexible circuit board 62 to control the display panel 611.

In some embodiments, the first flexible circuit board 62 includes a first connection portion 621, a first bending portion 622, a second connection portion 623, and a protrusion portion 624.

The first connecting portion 621 is mounted on the non-display surface 602 of the display module 61, and may be mounted on the non-display surface 602 of the display module 61 in an Anisotropic Conductive Film (ACF) manner, or may be fixed by glue.

The protruding portion 624 extends outward from one side edge of the first connecting portion 621, and the protruding portion 624 is connected to the circuit board 30. Thus, the first flexible circuit board 62 can be electrically connected to the circuit main board 30 in the electronic device 100. When the first flexible circuit board 62 is mounted on the non-display surface 602 of the display module 61, the protrusion 624 extends outward from one side edge of the display module 61, so as to facilitate connection with the circuit board 30.

Referring to fig. 10, the display module 61 further includes a first side 603 and a second side 604 opposite to the first side 603, the first side 603 and the second side 604 are located at two sides of the first end portion 60A and connected to the first end portion 60A, the first end portion 60A of the display module 61 is provided with an arc notch 610, the arc notch 610 extends from a center line of the display module 61 toward the first side 603 and the second side 604, the functional component is installed in the arc notch 610, and the functional component is in telecommunication connection with a circuit board.

In some embodiments, in the process of implementing a full-screen electronic device, it is usually necessary to provide a notch at the middle position of the end of the display screen to mount a functional component, that is, a so-called "bang-bang" electronic device, where the notch at the middle position of the electronic device is more abrupt, and therefore the appearance of the electronic device is greatly affected, and in this application, the arc notch 610 is disposed at the first end 60A, and the arc notch 610 extends from the first side 603 to the second side 604, so that the width of the notch can be increased, the height of the notch can be reduced, and the appearance of the electronic device cannot be affected by the electronic device having an abrupt "bang", and meanwhile, the installation space of the whole notch can be increased by such arrangement, so that more components can be conveniently mounted in the arc notch 610.

It should be noted that the functional components include a camera assembly, a receiver assembly, and the like, and in the embodiment of the present application, specific components included in the functional components are not specifically limited. It is understood that in the embodiment of the present application, the functional components required to be installed in the arc-shaped notch 610 may have a shape that is adapted to the shape of the arc-shaped notch 610 without interfering with each other. Therefore, for the specific installation manner of the functional component and the arc notch, no redundant description is given in the embodiment of the present application.

Wherein, the shape of the arc notch 610 is: the starting point 613 is a point that is located at one axial center line of the display module 61 and symmetrically extends toward the first side 603 and the second side 604 in an arc shape, and a farthest point of the arc notch 610 from the first end 60A. It will be appreciated that the arcuate indentation 610 may be "crescent shaped". Of course, the arc-shaped notch can also be in a shape of a semi-circle arc or the like. In the embodiment of the present application, the specific shape of the arc notch 610 is not described in detail. The arc notch 610 is formed by taking one point of the axial center line of the display module 61 as a starting point and extending symmetrically to the first side 603 and the second side 604 in an arc shape, and the farthest point of the arc notch 610 from the first end 60A is the starting point 613. Therefore, the arrangement can increase the installation space of the whole notch, and more functional components can be conveniently installed in the arc notch 610.

Wherein the distance between the starting point 613 and the edge of the first end portion 60A is less than 5 mm. It should be noted that the distance between the starting point 613 and the edge of the first end portion 60A may be 1mm, 3mm, 5mm, and the like, and the distance between the starting point 613 and the first end portion 60A is not particularly limited in the embodiment of the present application. It is understood that the smaller the distance between the starting point 613 and the edge of the first end portion 60A, the smaller the area of the arc-shaped notch 610 is, and the larger the display area is, so that the area of the arc-shaped notch 610 is reduced as much as possible to obtain a larger display area in the case of satisfying the installation of the functional components.

Referring to fig. 11, the arc notch 610 may further include a first notch portion 6101 and a second notch portion 6102, the first notch portion 6101 and the second notch portion 6102 are symmetrical along a central line of the display module 61, the first flexible circuit board 62 passes through the first notch portion 6101, and the second flexible circuit board 63 passes through the second notch portion 6102. Of course, the first flexible circuit board 62 may also pass through the first notch portion 6101 and the second notch portion 6102, and the second flexible circuit board 63 may also pass through the first notch portion 6101 and the second notch portion 6102. In the embodiment of the present application, the first flexible circuit board 62 passes through the first notch 6101, and the second bending portion 63 passes through the second notch 6102. This prevents the first flexible circuit board 62 and the second flexible circuit board 63 from being stacked, and facilitates the installation of the functional components in the arc-shaped notch 610.

In some embodiments, the first notch 6101 is close to the first side 603, and the second notch 6012 is close to the second side 604. Since the portion of the first flexible circuit board 62 passing through the first notch portion 6101 is close to the first side 603, and the portion of the second flexible circuit board 63 passing through the second notch portion 6102 is close to the second side 604, more space is left between the first notch portion 6101 and the second notch portion 6012 for mounting functional components.

In some embodiments, the first gap portion 6101 includes a first sub-gap 61011 and a second sub-gap 61012, the first sub-gap 61011 is connected to the second sub-gap 61012, the first sub-gap 61011 is close to the first side 603, the depth of the first sub-gap 61011 is less than the depth of the second sub-gap 61012, the second gap portion 6102 includes a third sub-gap 61021 and a fourth sub-gap 61022, the third sub-gap 61021 is connected to the fourth sub-gap 61022, the third sub-gap 61021 is close to the second side 604, and the depth of the third sub-gap 61021 is less than the depth of the fourth sub-gap 61022. It should be noted that the depth of the first sub-notch 61011 is smaller than the depth of the second sub-notch 61012, that is, the arc edge is not streamlined, but two arc edges with different radians correspondingly form the first sub-notch 61011 and the second sub-notch 61012. In addition, the shape of the second notch 6102 corresponds to the shape of the first notch 6101, and therefore, the description thereof is omitted. Because the depths of the first sub-gap 61011 and the third sub-gap 61021 are less than the depths of the second sub-gap 61012 and the third sub-gap 61022, the first flexible circuit board 62 passes through the first sub-gap 61011, and the second flexible circuit board 63 passes through the third sub-gap 61021, so that more space is left in the second sub-gap 61012 and the fourth sub-gap 61022 for installing other functional components.

Referring to fig. 12 and 13, the first connecting portion 621, the first bending portion 622 and the second connecting portion 623 are sequentially connected, and the first bending portion 622 covers the first end portion 61A.

The second flexible circuit board 63 may extend from the non-display surface 602 to the inside of the display module 61 by bypassing the first end portion 61A, and be electrically connected to the touch panel 612, so as to drive the display module 61 to implement the touch function. Accordingly, the touch instruction received by the touch panel 612 may be transmitted to the processor of the electronic device 100 through the second flexible circuit board 63.
