[0002] In related technologies, foldable screen phones typically have circuit boards on both sides of the device, and the two circuit boards are electrically connected by a flexible circuit board passing through the hinge.

[0003] However, this scheme has the following drawbacks:

[0004] 1. A flexible circuit board passing through a hinge will affect the structural strength of the hinge;

[0005] 2. Flexible circuit boards are difficult to install, hard to inspect, and have high maintenance costs;

[0006] 3. When the phone is folded, the flexible circuit board and the hinge will rub against each other, which will affect the lifespan of the flexible circuit board.

[0007] 4. Flexible circuit boards take up a lot of space in the body, which affects the thinness and lightness of the phone. Summary of the Invention

[0008] This application aims to provide a flexible screen component and electronic device that can solve the technical problems in related technologies, such as the need for flexible circuit boards to connect the circuit boards on both sides of the device body in foldable screen electronic devices, resulting in poor structural strength, difficult assembly, and large overall thickness of the electronic device.

[0009] To solve the above-mentioned technical problems, this application is implemented as follows:

[0010] In a first aspect, this application provides a flexible screen assembly, comprising:

[0011] main body;

[0012] A support layer is provided on one side of the main body. The support layer has a first through hole and a second through hole. The main body and the support layer have bending areas. The first through hole is located on one side of the bending area, and the second through hole is located on the other side of the bending area.

[0013] A flexible circuit board, a portion of which is located between the body and the support layer, and the flexible circuit board passes through a first through-hole and a second through-hole.

[0014] Secondly, this application provides an electronic device, comprising:

[0015] Such as the flexible screen component provided in the first aspect.

[0016] In the embodiments of this application, the flexible screen assembly includes a main body, a support layer, and a flexible circuit board. The main body is used to realize display and touch functions. The support layer is disposed on one side of the main body to provide support for the main body and improve the strength of the flexible screen assembly. The main body and the support layer have bending areas. The support layer has a first through hole and a second through hole on both sides of the bending area. A portion of the flexible circuit board is disposed between the main body and the support layer. One end of the flexible circuit board passes through the support layer through the first through hole, and the other end of the flexible circuit board passes through the support layer through the second through hole. Thus, the flexible circuit board can connect electronic components disposed on both sides of the bending area. After the flexible screen assembly is installed in the electronic device, the flexible circuit board can connect electronic components of different parts of the electronic device. The flexible circuit board does not affect the strength of the hinge. Furthermore, the structure is simple and easy to install and maintain. When the electronic device is folded, the flexible circuit board will not rub against the hinge, thus improving the service life of the flexible circuit board. In addition, the flexible circuit board occupies less space in the device body, which facilitates the arrangement of electronic device components and contributes to the thinning and lightening of the electronic device.

[0032] The following is combined with Figures 1 to 7 This application describes a flexible screen assembly 100 and an electronic device 200 according to embodiments thereof.

[0033] like Figure 1 , Figure 2 and Figure 3 As shown, this application provides a flexible screen assembly 100, including: a main body 110; a support layer 130 disposed on one side of the main body 110, the support layer 130 having a first through hole 132 and a second through hole 134, the main body 110 and the support layer 130 having a bending region 124, the first through hole 132 being located on one side of the bending region 124, and the second through hole 134 being located on the other side of the bending region 124; and a flexible circuit board 140, a portion of the flexible circuit board 140 being located between the main body 110 and the support layer 130, and the flexible circuit board 140 passing through the first through hole 132 and the second through hole 134.

[0034] In embodiments of this application, the flexible screen assembly 100 includes a main body 110, a support layer 130, and a flexible circuit board 140. The main body 110 is used to realize display and touch functions. The support layer 130 is disposed on one side of the main body 110 to provide support for the main body 110 and improve the strength of the flexible screen assembly 100. Furthermore, the main body 110 and the support layer 130 have bending regions 124. The support layer 130 has a first through hole 132 and a second through hole 134 on both sides corresponding to the bending regions 124. A portion of the flexible circuit board 140 is disposed between the main body 110 and the support layer 130. One end of the flexible circuit board 140 extends out of the support layer 130 through the first through hole 132, and the other end of the flexible circuit board 140 extends out of the support layer 130 through the second through hole 134. Thus, the flexible circuit board 140 can be connected to the flexible screen assembly 100 disposed on the main body 110 and the support layer 130. After the flexible screen assembly 100 is installed on the electronic device 200, the electronic components on both sides of the curved area 124 can be connected by the flexible circuit board 140. The flexible circuit board 140 does not affect the strength of the hinge assembly 230, allowing the hinge assembly 230 to cover the entire longitudinal area of ​​the electronic device 200, thereby improving the overall strength of the electronic device 200, enhancing its hovering and crease effects. Furthermore, the structure is simple, easy to install and maintain, and saves production costs. When the electronic device 200 is folded, the flexible circuit board 140 will not rub against the hinge, extending its service life. Additionally, the flexible circuit board 140 occupies less space in the device, facilitating the arrangement of components and contributing to the thinner and lighter design of the electronic device 200.

[0035] The support layer 130 can be made of plastic or metal, such as a steel support layer.

[0036] like Figure 1 , Figure 2 and Figure 3 As shown, as one possible implementation, it further includes: an auxiliary material layer 160 (C-Panel) disposed between the main body 110 and the support layer 130. The auxiliary material layer 160 has a receiving space 162, which is connected from one side of the bending region 124 to the other side of the bending region 124. The first through hole 132 and the second through hole 134 are both connected to the receiving space 162. A portion of the flexible circuit board 140 is located in the receiving space 162.

[0037] Specifically, an auxiliary material layer 160 is provided between the main body 110 and the support layer 130. The auxiliary material layer 160 has a receiving space 162, which can be a groove 144 with its opening facing the support layer 130, or an opening that runs along the direction from the support layer 130 to the main body 110. The first through hole 132 and the second through hole 134 on the support layer 130 are both connected to the receiving space 162. The flexible circuit board 140 passes through the receiving space 162 and through the first through hole 132 and the second through hole 134 to achieve electrical connection between the electronic components on both sides of the bending area 124. The auxiliary material layer 160 acts as a buffer between the main body 110 and the support layer 130. The receiving space 162 on the auxiliary material layer 160 is formed by cutting off a portion of a whole auxiliary material board or drilling a hole in a whole auxiliary material board. The main body 110 is provided on one side of the auxiliary material layer 160, and the support layer 130 is provided on the other side.

[0038] Furthermore, the auxiliary layer 160 can provide support between the support layer 130 and the main body 110, reduce the wear of the flexible circuit board 140 on the flexible circuit board 140 and the main body 110 on the flexible circuit board 140, and reduce the wear of the support layer 130 on the main body 110, thereby improving the service life of the flexible screen assembly 100.

[0041] Specifically, an etched texture area 142 is provided at the position of the flexible circuit board 140 corresponding to the bending area 124. Since the position of the flexible circuit board 140 corresponding to the bending area 124 is often in a bending state, this position is set as an etched texture area 142 to reduce the rigidity of this position, reduce the possibility of the flexible circuit board 140 being damaged due to bending, and improve the service life of the flexible screen assembly 100.

[0042] like Figure 5 As shown, in one possible implementation, the etched texture area 142 includes multiple grooves 144.

[0046] Specifically, the flexible circuit board 140 includes a first circuit section 146, a first connector 148, and a second connector 150. The first circuit section 146 conducts through the first connector 148 and the second connector 150, and the first connector 148 and the second connector 150 are used to connect different electronic components on the electronic device 200. After the first circuit section 146 is installed, the first connector 148 and the second connector 150 can be fixed to the first circuit section 146, thereby reducing the installation difficulty of the flexible circuit board 140 and the electronic components and improving production efficiency.

[0047] The first connector 148 can be a male or female plug structure on a board-to-board connector.

[0050] Specifically, the flexible circuit board 140 also includes a second circuit section 152 and a third connector 154. The second circuit section 152 is electrically connected to the main body 110, and the third connector 154 is used to electrically connect with electronic components on the electronic device 200, thereby realizing the electrical connection between the flexible circuit board 140 and the electronic components on the electronic device 200, and realizing display, touch and recognition functions of the flexible screen assembly 100.

[0053] Specifically, the first circuit section 146 and the second circuit section 152 are integrated, thereby reducing the number of components in the flexible screen assembly 100 and reducing the installation steps. The third connector 154 and the second connector 150 are arranged side by side, reducing the connection positions of the flexible screen assembly 100 and reducing the installation steps of the flexible screen assembly 100 and electronic components on the electronic device 200, thereby improving production efficiency.

The protective layer 112 protects the polarizing layer 116 and the circuit layer 120.
