Description

Technical Field

[0001] This application relates to the technical field of electronic products, and particularly to a display module, a processing method thereof, a flexible circuit board assembly, and an electronic device. Background Art

[0002] As an essential part of an electronic device, a display module can provide functions of information display and interactive operation for users. The production process flow of a display module includes substrate preparation, lithography process, lamination process, assembly, testing, packaging, etc. Each process has its corresponding process equipment, and the ultimate size of these process equipment, that is, the maximum size that can accommodate the display module, needs to match the length, width, etc. of the display module to ensure precise processing and production efficiency during the production process.

[0003] However, during the production process, the size of the display module, especially the length, exceeds the ultimate length of the process equipment, resulting in interference between the display module and the process equipment, thereby affecting the electrical performance of the display module. Summary of the Invention

[0004] Embodiments of this application provide a display module, a processing method thereof, a flexible circuit board assembly, and an electronic device, which are used to solve the problem of interference between the display module and the process equipment during the production process.

[0005] To achieve the above object, the embodiments of this application adopt the following technical solutions:

[0006] In a first aspect, embodiments of this application provide a processing method for a display module. The display module includes a display substrate and a flexible circuit board. The flexible circuit board includes opposite first and second ends. The processing method includes: bending the second end of the flexible circuit board towards the first end so that the flexible circuit board forms a first straight section, a bent section, and a second straight section that are sequentially connected, wherein the first straight section and the second straight section are spaced apart and located on the same side of the bent section, the first end is the end of the first straight section away from the bent section, and the second end is the end of the second straight section away from the bent section; connecting the first end of the flexible circuit board to the display substrate.

[0007] The processing method for the display module provided by the embodiments of this application bends the second end of the flexible circuit board towards the first end to form a bent section, and then connects the first end of the flexible circuit board to the display substrate. In this way, the structural length after the flexible circuit board is connected to the display substrate is reduced, so that the ultimate length of the process equipment can be matched, and interference between the display module and the process equipment during the production process can be avoided, thereby affecting the electrical performance, and the yield rate of the display module production can be guaranteed.

[0008] In some possible implementations of the first aspect, before connecting the first end of the flexible circuit board to the display substrate, the method includes: supporting the first straight section and the second straight section to keep the bent section stable in the bent state.

[0009] In this way, by supporting the first straight section and the second straight section, the bent section can be kept stable in the bent state, and creases or even dead folds on the bent section can be avoided, so as to prevent the circuits and components on the flexible circuit board from being damaged by external impacts or squeezes, and further prevent the flexible circuit board from being damaged or broken, which affects the electrical performance, so as to ensure the yield rate of the display module production.

[0010] In some possible implementations of the first aspect, supporting the first straight section and the second straight section includes: arranging a first support member between the first end and the second end of the flexible circuit board and connecting the first support member to the flexible circuit board; after bending the second end of the flexible circuit board towards the first end, connecting the first support member and the second straight section.

[0011] In this way, by arranging the first support member before bending the flexible circuit board, an accurate bending position and angle can be provided, ensuring that the flexible circuit board maintains an accurate shape and size during the bending process, so that creases on the bent section can be more effectively avoided, and further preventing the flexible circuit board from being damaged or broken.

[0012] In some possible implementations of the first aspect, supporting the first straight section and the second straight section further includes: connecting an adapter to the second end of the flexible circuit board, where the adapter is used to connect to an electrical performance test device; after bending the second end of the flexible circuit board towards the first end, connecting the adapter and the first support member.

[0013] In this way, by electrically connecting the flexible circuit board to the adapter, it can be verified whether the electrical performance of the bent flexible circuit board and the bent flexible circuit board after being connected to the display substrate meets the design requirements, so as to ensure that the flexible circuit board can still work stably and reliably after being bent, and ensure the yield rate of the display module during the production process.

[0014] By arranging the adapter and the first support member to support the first straight section and the second straight section, the bent section formed after bending the flexible circuit board is kept in the bent state, so that the flexible circuit board can maintain its shape and stability when being bent. In addition, the first support member can also support the adapter, improving the compactness of the whole structure. The adapter is used to test the electrical performance of the bent flexible circuit board to ensure that the flexible circuit board can still work stably and reliably after being bent, and ensure the yield rate of the display module during the production process.

[0015] In some possible implementations of the first aspect, a groove is formed on a side of the first support member away from the first straight section, and a reinforcing member is provided on a side of the adapter away from the second straight section. Connecting the adapter and the first support member includes connecting the reinforcing member to the groove.

[0016] In this way, by connecting the reinforcing member to the groove to connect the adapter and the first support member, the first support member and the adapter can stably support the first straight section and the second straight section, thereby better maintaining the stability of the bent shape of the flexible circuit board. In addition, providing the reinforcing member on the adapter is beneficial to improving the mechanical strength and structural stability of the adapter, enabling the adapter to better withstand external stress and vibration, and ensuring that the adapter can work stably and reliably.

[0017] In some possible implementations of the first aspect, supporting the first straight section and the second straight section further includes: disposing a second support member between the first end and the second end of the flexible circuit board, and being relatively closer to the second end of the flexible circuit board than the first support member, and connecting the second support member to the flexible circuit board.

[0018] In this way, by providing the second support member to support the first straight section and the second straight section, the bent section formed after the flexible circuit board is bent is maintained in the bent state, so that the flexible circuit board can maintain its shape and stability when bent. At the same time, the second support member can cooperate with the first support member and the adapter to support the first straight section and the second straight section, improving the stability of the flexible circuit board in maintaining the bent shape, and can also perform electrical performance tests on the bent flexible circuit board and after the bent flexible circuit board is connected to the display substrate, ensuring that the flexible circuit board can still work stably and reliably after being bent, and ensuring the yield rate of the display module during the production process.

[0019] In some possible implementations of the first aspect, the inner diameter of the bent section is greater than or equal to 1.4 mm.

[0020] In this way, by keeping the inner diameter of the bent section at a value greater than or equal to 1.4 mm, it is possible to avoid creases or even dead folds in the bent section, thereby ensuring the bent shape of the bent section and the working reliability of the flexible circuit board.

[0021] In some possible implementations of the first aspect, the processing method further includes: bending one end of the display substrate close to the flexible circuit board toward the other end of the display substrate and away from the side where the light-emitting side of the display substrate is located to obtain a semi-finished product of the display module; testing the electrical performance of the semi-finished product of the display module; removing the first support member, the second support member, and the adapter, bending the second end of the flexible circuit board away from the first end of the flexible circuit board, and making the first straight section and the second straight section lie in the same plane to obtain the display module.

[0022] In this way, by bending one end of the display substrate close to the flexible circuit board towards the other end of the display substrate and away from the side where the light-emitting side of the display substrate is located, then performing electrical performance testing, and finally removing the first support member, the second support member, and the adapter, the second straight section and the first straight section are located in the same plane, and the final display module is obtained. During the production process of the display module, the first support member, the second support member, and the adapter are used to maintain the stability of the bending form of the flexible circuit board and ensure its good electrical performance, and the adapter is used to ensure the stability of the electrical performance of the semi-finished display module, thereby ensuring the yield rate of the display module production.

[0023] In a second aspect, an embodiment of the present application provides a display module, and the display module is manufactured by the processing method of the above display module.

[0024] Since the display module provided by the embodiment of the present application is manufactured by the processing method of the above display module, the two can solve the same problems and achieve the same effects.

[0025] In a third aspect, an embodiment of the present application provides an electronic device, and the electronic device includes the above display module.

[0026] Since the electronic device provided by the embodiment of the present application includes the above display module, the two can solve the same problems and achieve the same effects.

[0027] In a fourth aspect, an embodiment of the present application provides a flexible circuit board assembly, and the flexible circuit board assembly includes a flexible circuit board and an auxiliary support assembly. Wherein, the flexible circuit board includes a first straight section, a bending section, and a second straight section connected in sequence, the first straight section and the second straight section are arranged at intervals and are located on the same side of the bending section, and the part of the first straight section far from the bending section extends out of the second straight section, and the auxiliary support assembly is arranged between the first straight section and the second straight section and is respectively connected to the first straight section and the second straight section.

[0028] In the flexible circuit board assembly provided by the embodiment of the present application, by arranging an auxiliary support assembly between the first straight section and the second straight section to support the first straight section and the second straight section, the bending section can be stably in the bent state, which can avoid the generation of creases or even dead folds in the bending section, thereby avoiding damage to the circuits and components on the flexible circuit board due to external impact or extrusion, and further avoiding damage or breakage of the flexible circuit board and affecting the electrical performance, so as to ensure the yield rate of the flexible circuit board assembly production.

[0029] In some possible implementation manners of the fourth aspect, the inner diameter of the bending section is greater than or equal to 1.4 mm.

[0030] In this way, by keeping the inner diameter of the bent section greater than or equal to 1.4 mm, it is possible to avoid creases or even dead folds in the bent section, thereby ensuring the bending shape of the bent section and the working reliability of the flexible circuit board.

[0031] In some possible implementation manners of the fourth aspect, the auxiliary support assembly includes a first support member disposed between the first straight section and the second straight section. The first support member is used to support the first straight section and the second straight section and is connected to the first straight section and the second straight section.

[0032] In this way, by providing the first support member between the first straight section and the second straight section, the bent section formed after the flexible circuit board is bent is maintained in a bent state, enabling the first support member to support the first straight section and the second straight section. Thus, the bent section formed after the flexible circuit board is bent can have a stable bent state, and further enables the flexible circuit board to maintain its shape and stability when bent.

[0033] In some possible implementation manners of the fourth aspect, the auxiliary support assembly further includes an adapter disposed between the second straight section and the first support member and connecting the second straight section and the first support member. The adapter is used to connect to an electrical performance testing device.

[0034] In this way, by providing the adapter and the first support member to support the first straight section and the second straight section, the bent section formed after the flexible circuit board is bent is maintained in a bent state, so that the flexible circuit board can maintain its shape and stability when bent. Additionally, the first support member can also support the adapter, improving the compactness of the entire structure. Using the adapter to perform electrical performance testing on the bent flexible circuit board ensures that the flexible circuit board can still work stably and reliably after being bent, guaranteeing the yield rate of the production of the flexible circuit board assembly.

[0035] In some possible implementation manners of the fourth aspect, a groove is formed on one side of the first support member facing the adapter, and a reinforcing member is disposed on one side of the adapter facing the first support member, with the reinforcing member connected to the groove.

[0036] In this way, by connecting the reinforcing member to the groove to connect the adapter and the first support member, the first support member and the adapter can stably support the first straight section and the second straight section, thereby better maintaining the stability of the bending shape of the flexible circuit board. Additionally, providing the reinforcing member on the adapter is conducive to improving the mechanical strength and structural stability of the adapter, enabling the adapter to better withstand external stress and vibration, and ensuring that the adapter can work stably and reliably.

[0037] In some possible implementations of the fourth aspect, the auxiliary support component further includes a second support member. The second support member is disposed between the first straight section and the second straight section and is connected to the first straight section. The second support member is disposed on a side of the first support member close to the bent section.

[0038] In this way, by providing the second support member to support the first straight section and the second straight section, the bent section formed after the flexible circuit board is bent is maintained in a bent state. Thus, the flexible circuit board can maintain its shape and stability when bent. At the same time, the second support member can cooperate with the first support member and the adapter to support the first straight section and the second straight section, improving the stability of the flexible circuit board in maintaining the bent form, and can also perform electrical performance tests on the flexible circuit board in the bent form to ensure that the flexible circuit board can still work stably and reliably after being bent, ensuring the yield rate of the production of the flexible circuit board assembly.

[0039] In a fifth aspect, an embodiment of the present application provides a display module assembly. The display module assembly includes a display substrate and the above flexible circuit board assembly. Among them, the display substrate includes a bent portion. Along a direction perpendicular to the plane where the display substrate is located, the first straight section is spaced apart from the display substrate, and one end of the first straight section far from the bent section is connected to the bent portion.

[0040] The display module assembly provided by the embodiment of the present application uses the auxiliary support component and the adapter to maintain the stability of the bent form of the flexible circuit board assembly and ensure its good electrical performance, and then uses the adapter to ensure the stability of the electrical performance of the display module, thereby ensuring the yield rate of the production of the display module.

In the embodiments of the present application, the form of the electronic device is not specifically limited.

[0066] Please refer to Figure 1 , Figure 1 which is a perspective view of the electronic device 100 provided in some embodiments of the present application. In this embodiment and the following embodiments, the electronic device 100 is taken as a handheld device with wireless communication function for illustrative purposes. The handheld device with wireless communication function can be, for example, a mobile phone. The electronic device 100 is generally in the shape of a rectangular flat plate. Based on this, in order to facilitate the description of the following embodiments, an XYZ coordinate system is established. Specifically, the width direction of the electronic device 100 is defined as the X-axis direction, the length direction of the electronic device 100 is defined as the Y-axis direction, and the thickness direction of the electronic device 100 is defined as the Z-axis direction. It can be understood that the coordinate system of the electronic device 100 can be flexibly set according to actual needs and is not specifically limited herein. When the electronic device 100 is other products, the electronic device 100 can also be generally in the shape of a square flat plate, a circular flat plate, etc., which is not specifically limited herein.

[0067] Please refer to Figure 1 and Figure 2 , Figure 2 which is Figure 1 a schematic exploded view of the electronic device 100 shown in the figure. The electronic device 100 includes a display module 10, a back shell 20, and a main board 30.

[0068] It can be understood that Figure 1 and Figure 2Schematically shown are some components included in the electronic device 100, and the actual shape, actual size, actual position, and actual structure of these components are not limited by Figure 1 and Figure 2 .

[0069] The display module 10 is used to display images, videos, etc. The display module 10 includes a light-transmitting cover plate 11 and a display screen 12, and the display screen 12 includes a display substrate (not shown in the figure). The light-transmitting cover plate 11 and the display screen 12 are stacked. The light-transmitting cover plate 11 is mainly used to protect the display screen 12 and prevent dust. The material of the light-transmitting cover plate 11 includes but is not limited to glass. The display screen 12 can be a flexible display screen or a rigid display screen. For example, the display screen 12 can be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a mini light-emitting diode display screen, a micro light-emitting diode display screen, a micro organic light-emitting diode display screen, a quantum dot light-emitting diode (QLED) display screen, or a liquid crystal display (LCD).

[0070] The back shell 20 is connected to the display module 10, and the back shell 20 is used to protect the internal electronic components of the electronic device 100.

[0071] In some embodiments, please refer to Figure 1 and Figure 2 together. The back shell 20 may include a back plate 21 and a middle frame 22. The back plate 21 is located on the side of the display screen 12 away from the light-transmitting cover plate 11 and is spaced from the display screen 12. The middle frame 22 is located between the back plate 21 and the display module 10 and is arranged along the edges of the back plate 21 and the display module 10. The middle frame 22 is fixed to the back plate 21. Exemplarily, the middle frame 22 can be fixedly connected to the back plate 21 by adhesive. Of course, the middle frame 22 and the back plate 21 can be an integrally formed structure to increase the structural compactness of the electronic device 100.

[0072] There is a receiving cavity (not shown in the figure) inside the back shell 20, and the main board 30 is placed in the receiving cavity. The main board 30 is electrically connected to the display module 10. The main board 30 is responsible for controlling various functions of the entire device, including the display function, while the display module 10 is responsible for displaying images or information. The main board 30 can transmit image signals, touch signals, and other control signals to the display module 10 to control the display content and interactive functions. At the same time, the main board 30 can also transmit power signals to the display module 10 to supply the power required for the operation of the display screen 12.

[0073] In addition to including the light-transmitting cover plate 11 and the display screen 12, the display module 10 also includes a flexible circuit board connecting the display screen 12 and the main board 30 of the electronic device 100. The flexible circuit board is usually first connected to the display screen 12, and during the assembly of the whole machine, the flexible circuit board is then electrically connected to the main board 30. The flexibility and thin design of the flexible circuit board enable it to easily pass through the space inside the electronic device 100. For example, the flexible circuit board can pass through the middle frame 22 to connect to the main board 30, and can transmit signals and power to the display module 10, thereby realizing the display function.

[0074] The general production process of the traditional display module is as follows: First, the bonded display substrate and the flexible circuit board are placed on the workbench of the processing equipment. Among them, the display substrate and the flexible circuit board are located on the same processing surface. Then, the light-transmitting cover plate and copper foil are attached to the display substrate. The copper foil is used to support the display substrate. Finally, the bent portion of the display substrate is bent towards the non-light-emitting side of the display screen 12, so that the flexible circuit board is stacked on the non-light-emitting side of the display screen 12, thus completing the production of the display module.

[0075] It can be understood that the same processing surface means that the display substrate and the flexible circuit board are sequentially placed on the workbench along a direction parallel to the tabletop of the workbench. The display substrate and the flexible circuit board can be located on the same processing plane. Of course, the display substrate and the flexible circuit board can also be located on two different processing planes with a small height difference.

[0076] During the production process of the above display module, the workbench of the processing equipment used has a limit size, that is, the maximum size that can accommodate the connected display substrate and flexible circuit board. If the total length of the connected display substrate and flexible circuit board is greater than the maximum length of the processing equipment, then during the production process of the display module, the part of the display substrate and the flexible circuit board that exceeds the maximum length will interfere with the processing equipment, that is, the excess part will contact the processing equipment. On the one hand, it will interfere with the process flow, and on the other hand, it will cause damage to the display substrate and the flexible circuit board, thereby affecting the electrical performance of the display substrate and the flexible circuit board, and further reducing the yield rate of the display module production.

[0077] Based on this, in order to solve the above problems, from the perspective of avoiding interference between the display module and the process equipment during the production process, the present application provides a processing method for a display module, which can ensure that the size of the display module adapts to the limit size of the process equipment during the production process, thereby avoiding interference between the display module and the process equipment.

[0078] The following describes the processing method of the display module in combination with the specific production process of the above display module.

[0079] Please refer to Figure 3 and Figure 4 , the embodiment of the present application provides a processing method for a display module 10. The display module 10 includes a display substrate 121 and a flexible circuit board 13. The flexible circuit board 13 includes opposite first end 1301 and second end 1302. The processing method includes:

[0080] Step S100, bending the second end of the flexible circuit board towards the first end, so that the flexible circuit board forms a first straight section, a bent section and a second straight section connected in sequence, wherein the first straight section and the second straight section are arranged at intervals and are located on the same side of the bent section. The first end is the end of the first straight section away from the bent section, and the second end is the end of the second straight section away from the bent section.

[0081] Step S200, connecting the first end of the flexible circuit board to the display substrate.

[0082] Please refer to Figure 4 , in step S100, the flexible circuit board 13 has opposite first end 1301 and second end 1302 along its length direction, wherein the first end 1301 is Figure 4 the right end shown in Figure 4 and the second end 1302 is

[0083] Please refer to Figure 5 and Figure 6 , bending the left end of the flexible circuit board 13 towards the right end side to form a first straight section 131, a second straight section 132 and a bent section 133, wherein the first straight section 131 is Figure 6 the part located below shown in Figure 6 and the second straight section 132 is

[0084] Exemplarily, the bending of the flexible circuit board 13 can be achieved by a bending machine, a bending die, etc., to ensure that the flexible circuit board 13 will not be subjected to excessive stress during the bending process.

[0085] Please refer toFigure 7 , in step S200, the physical and electrical connection between the flexible circuit board 13 and the display substrate 121 can be achieved by setting an anisotropic conductive film (ACF for short) between the end of the first end of the flexible circuit board 13 and the end of the display substrate 121. ACF adhesive is a special adhesive that is insulating in its normal state but can become conductive when pressure or heat is applied. ACF adhesive is usually composed of a mixture of conductive particles and an adhesive, and the conductive particles can be materials such as metals or carbon nanotubes. After setting the ACF adhesive between the flexible circuit board 13 and the display substrate 121, by applying pressure or heat, the conductive particles will form a conductive path in the vertical direction, thereby achieving the electrical connection between the flexible circuit board 13 and the display substrate 121.

[0086] The processing method of the display module 10 provided by the embodiments of the present application bends the second end 1302 of the flexible circuit board 13 toward the first end 1301 to form a bent section 133, stabilizes the bent section 133 in the bent state, and then connects the first end 1301 of the flexible circuit board 13 to the display substrate 121. In this way, the structural length after the connection between the flexible circuit board 13 and the display substrate 121 is reduced, so that the limit length of the process equipment can be matched, and the display module 10 can be prevented from being damaged due to interference with the process equipment during the production process, thereby ensuring that the display module 10 maintains good electrical performance during the production process and finally ensuring the yield rate of the production of the display module 10.

[0087] The present application changes the size of the flexible circuit board 13 to match the limit size of the process equipment, so that the flexible circuit board 13 and the display substrate 121 can adapt to process equipment with different limit sizes, thereby eliminating the need for large-scale modification of the process equipment, ensuring the on-time delivery of products, and greatly reducing the modification cost.

[0088] Please continue to refer to Figure 5 and Figure 6 , before connecting the first end 1301 of the flexible circuit board 13 to the display substrate 121, the method includes:

[0089] Step S110: Support the first straight section 131 and the second straight section 132 to stabilize the bent section 133 in the bent state.

[0090] In this way, stabilizing the bent section 133 in the bent state can prevent the bent section 133 from generating creases or even dead folds, thereby preventing the circuits and components on the flexible circuit board 13 from being damaged by external impacts or squeezes, and further preventing the flexible circuit board 13 from being damaged or broken, which affects the electrical performance, so as to ensure the yield rate of the production of the display module 10.

[0091] Exemplarily, please continue to refer toFigure 5 and Figure 6 , before the second end 1302 of the flexible circuit board 13 bends towards the first end 1301, a support structure 40 is arranged between the first end 1301 and the second end 1302 of the flexible circuit board 13. After the second end 1302 of the flexible circuit board 13 bends towards the first end 1301, the support structure 40 is located between the first straight section 131 and the second straight section 132. By supporting the first straight section 131 and the second straight section 132 through the support structure 40, the bent section 133 is enabled to maintain the bent shape, which can avoid the bent section 133 from generating creases or even dead folds, thereby avoiding the circuits and components on the flexible circuit board 13 from being damaged by external impacts or squeezes, and further avoiding the flexible circuit board 13 from being damaged or broken and affecting the electrical performance, ensuring the working reliability of the flexible circuit board 13.

[0092] Exemplarily, the support structure 40 can be a spacer block, and the material of the spacer block can be foam, plastic, etc.

[0093] Exemplarily, the support structure 40 can be connected to the first straight section 131 and the second straight section 132 by means of adhesive bonding, magnetic attraction connection, etc.

[0094] In some possible embodiments, the support structure 40 is arranged between the first straight section 131 and the second straight section 132, an adhesive layer is arranged between the support structure 40 and the first straight section 131 to bond the support structure 40 and the first straight section 131, and an adhesive layer is arranged between the support structure 40 and the second straight section 132 to bond the support structure 40 and the second straight section 132.

[0095] Exemplarily, the adhesive layer can be a reusable adhesive. This adhesive has good adhesion, can firmly bond the support structure 40 and the flexible circuit board 13. At the same time, it also has easy removability and can be easily disassembled, avoiding leaving residues or damaging the surfaces of the support structure 40 and the flexible circuit board 13. In addition, this adhesive can be reused, can be pasted and disassembled multiple times, and the viscosity will not decrease significantly.

[0096] In some other possible embodiments, the support structure 40 is arranged between the first straight section 131 and the second straight section 132. A first magnetic attraction part and a second magnetic attraction part are arranged on the support structure 40, a third magnetic attraction part is arranged on the first straight section 131, and a fourth magnetic attraction part is arranged on the second straight section 132. Among them, the first magnetic attraction part can be magnetically attracted to the third magnetic attraction part to connect the support structure 40 and the first straight section 131, and the second magnetic attraction part can be magnetically attracted to the fourth magnetic attraction part to connect the support structure 40 and the second straight section 132.

[0097] Under the action of an external force, applying a pulling force away from the first straight section 131 to the second straight section 132 can separate the second straight section 132 from the support structure 40, and applying a pulling force away from the second straight section 132 to the first straight section 131 can separate the first straight section 131 from the support structure 40.

[0098] It can be understood that, without causing electromagnetic interference to the flexible circuit board 13, by adjusting the strength and position of the first magnetic attraction portion, the second magnetic attraction portion, the third magnetic attraction portion, and the fourth magnetic attraction portion, the connection stability between the support structure 40 and the flexible circuit board 13 can be achieved.

[0099] In some embodiments, the inner diameter of the bending section 133 is greater than or equal to 1.4 mm. In this embodiment, the inner diameter of the bending section 133 can be set to 1.6 mm.

[0100] In this way, by keeping the inner diameter of the bending section 133 at a value greater than or equal to 1.4 mm, it is possible to avoid creases or even dead folds in the bending section 133, thereby ensuring the bending shape of the bending section 133 and the working reliability of the flexible circuit board 13.

[0101] Exemplarily, the height of the support structure 40 can be set according to the inner diameter of the bending section 133, as long as the bending section 133 is stabilized in the bent state to avoid creases or even dead folds. In this embodiment, the distance between the top surface of the second straight section 132 and the bottom surface of the first straight section 131 does not exceed 2 mm, and can be set to 1.4 mm, for example. With such a setting, it is possible to ensure that the bending section 133 is stably maintained in the bent state.

[0102] In some other embodiments, the first straight section and the second straight section can also be supported by providing a first support structure and a second support structure, so that the bending section 133 is stabilized in the bent state. The first support structure and the second support structure can be support clips. The first support clip clamps the first straight section 131, and the second support clip clamps the second straight section 132, which can also form the support for the first straight section 131 and the second straight section 132.

[0103] In some embodiments, supporting the first straight section and the second straight section includes:

[0104] Step S111: Dispose the first support member between the first end and the second end of the flexible circuit board, and connect the first support member to the flexible circuit board.

[0105] Step S112: After bending the second end of the flexible circuit board towards the first end, connect the first support member and the second straight section.

[0106] Please continue to refer to Figure 5 and Figure 6 , the first support member 41 isFigure 5 and Figure 6 the support structure 40 shown in

[0107] In this way, by providing the first support member 41 to support the first straight section 131 and the second straight section 132, the bent section 133 is stabilized in the bent state, which can avoid the generation of creases or even dead folds in the bent section 133, thereby preventing the circuits and components on the flexible circuit board 13 from being damaged by external impacts or squeezes, and further avoiding damage or breakage of the flexible circuit board 13 and affecting its electrical performance.

[0108] Exemplarily, the first support member 41 can be a foam, a plastic plate, or the like.

[0109] By providing the first support member 41 before bending the flexible circuit board 13, during the process of bending the second end of the flexible circuit board 13 towards the first end, the bent section 133 and the second straight section 132 can move smoothly in one direction until the bottom of the second straight section 132 directly contacts and connects with the top of the first support member 41. If the first support member 41 is provided after bending the flexible circuit board 13, then during the process of bending the second end of the flexible circuit board 13 towards the first end, the bent section 133 and the second straight section 132 may move excessively in one direction, that is, during the bending process, the distance between the second straight section 132 and the first straight section 131 will be less than the height of the first support member 41. At this time, it is necessary to move the bent section 133 and the second straight section 132 in the opposite direction again until the distance between the first straight section 131 and the second straight section 132 is greater than the height of the first support member 41, then place the first support member 41 between the first straight section 131 and the second straight section 132, and finally connect the second straight section 132 and the first support member 41. During this repeated bending process, creases or even dead folds may be generated in the bent section 133.

[0110] Thus, by providing the first support member 41 before bending the flexible circuit board 13, an accurate bending position and angle can be provided, ensuring that the flexible circuit board 13 maintains an accurate shape and size during the bending process, thereby more effectively avoiding the generation of creases in the bent section 133, and further avoiding damage or breakage of the flexible circuit board 13.

[0111] Exemplarily, the first support member 41 can be connected to the first straight section 131 and the second straight section 132 by means of adhesive bonding, magnetic attraction connection, or the like.

[0112] Exemplarily, the distance between the first support member 41 and the bent section 133 can be set as needed, as long as it is ensured that the first support member 41 can keep the bent section 133 in a stable bent form.

[0113] Please refer to Figure 8 and Figure 9, in some possible embodiments, to support the first straight section and the second straight section, it further includes:

[0114] Step S1111: Connect the adapter to the second end of the flexible circuit board, and the adapter is used to connect the electrical performance testing device.

[0115] Step S1121: After bending the second end of the flexible circuit board towards the first end, connect the adapter and the first support member.

[0116] In step S1111, the adapter 60 is a connecting wire made of a flexible circuit board, usually composed of one or more layers of thin film circuit boards. The adapter 60 is used for signal transmission and power supply between each circuit board and each component in the electronic device 100. A test interface is provided on the adapter 60, which can be connected to the electrical performance testing device. By using the adapter 60 to connect the flexible circuit board 13 and the electrical performance testing device, the electrical performance of the flexible circuit board 13 and the electrical performance after the flexible circuit board 13 is connected to the display substrate 121 can be tested.

[0117] Exemplarily, the electrical performance testing device can be an oscilloscope, a signal generator, a voltmeter, an ammeter, etc.

[0118] In this way, by electrically connecting the flexible circuit board 13 to the adapter 60, it can be verified whether the electrical performance of the bent flexible circuit board 13 meets the design requirements, and whether the electrical performance of the bent flexible circuit board 13 and the display substrate after bonding meets the design requirements, so as to ensure that the flexible circuit board 13 can still work stably and reliably after being bent, and ensure the yield rate of the display module 10 during the production process.

[0119] Continue to refer to Figure 8 , exemplarily, the flexible circuit board 13 and the adapter 60 can be physically and electrically connected through a board-to-board connector or a flexible electrical connector. One of the opposite surfaces of the second end 1302 of the flexible circuit board 13 is provided with a board-to-board connector, and one of the opposite surfaces of the adapter 60 is provided with a corresponding board-to-board connector. The board-to-board connector on the flexible circuit board 13 and the board-to-board connector on the adapter 60 are snapped together to connect the flexible circuit board 13 and the adapter 60.

[0120] It can be understood that a reinforcing plate 134 is provided on the other one of the opposite surfaces of the second end 1302 of the flexible circuit board 13, and a reinforcing member 61 is provided on the other one of the opposite surfaces of the adapter 60. By providing the reinforcing plate 134 and the reinforcing member 61, the mechanical strength and stability of the board-to-board connector can be enhanced, thereby reducing the displacement and deformation of the connector and improving the durability and reliability of the connector.

[0121] Exemplarily, the reinforcing plate 134 and the reinforcing member 61 can be connected to the flexible circuit board 13 and the adapter 60 respectively by means of threaded connection, adhesive bonding, etc.

[0122] Exemplarily, the materials of the reinforcing plate 134 and the reinforcing member 61 can be materials such as aluminum alloy, stainless steel, polymer composite material, etc., which have high strength and rigidity and can provide good support and protection.

[0123] In step S1121, before the second end 1302 of the flexible circuit board 13 is bent toward the first end 1301, the adapter 60 and the first support member 41 are both connected and arranged between the first end 1301 and the second end 1302 of the flexible circuit board 13, and both the adapter 60 and the first support member 41 are located on the same side of the flexible circuit board 13, and the adapter 60 is closer to the second end 1302 of the flexible circuit board 13 than the first support member 41. After the second end 1302 of the flexible circuit board 13 is bent toward the first end 1301, the first support member 41 is located between the adapter 60 and the first straight section 131, and then the first support member 41 is connected to the adapter 60. In this way, the first support member 41 and the adapter 60 cooperate together to support the first straight section 131 and the second straight section 132.

[0124] In this way, by arranging the adapter 60 and the first support member 41 to support the first straight section 131 and the second straight section 132, the bent section 133 formed after the flexible circuit board 13 is bent is kept in the bent state, so that the flexible circuit board 13 can maintain its shape and stability when bent. In addition, the first support member 41 can also support the adapter 60, improving the compactness of the whole structure. The adapter 60 is used to perform electrical performance tests on the bent flexible circuit board 13 and the connected bent flexible circuit board 13 and the display substrate, ensuring that the flexible circuit board 13 can still work stably and reliably after being bent, and guaranteeing the yield rate of the display module 10 during the production process.

[0125] It can be understood that the setting steps of the first support member 41 and the adapter 60 are not specifically limited in this embodiment. The above processing method can also be: before the second end 1302 of the flexible circuit board 13 is bent toward the first end 1301, only the first support member 41 is connected and arranged between the first end 1301 and the second end 1302 of the flexible circuit board 13. After the second end 1302 of the flexible circuit board 13 is bent toward the first end 1301, the second end 1302 of the flexible circuit board 13 is snap-connected to the adapter 60, and then the adapter 60 is connected to the first support member 41, so that the adapter 60 and the first support member 41 cooperate together to support the first straight section 131 and the second straight section 132.

[0126] Exemplarily, the material of the first support member 41 described above may be a material with high strength such as ceramics or plastics.

[0127] Exemplarily, the first support member 41 may be connected to the adapter 60 by means such as bonding or threaded connection.

[0128] Continue to refer to Figure 8 and Figure 9 In some possible embodiments, a groove 410 is formed on the side of the first support member 41 away from the first straight section 131, and a reinforcing member 61 is provided on the side of the adapter 60 away from the second straight section 132. Connecting the adapter and the first support member includes:

[0129] Step S1122: Connect the reinforcing member to the groove.

[0130] Before the second end 1302 of the flexible circuit board 13 is bent toward the first end 1301, a groove 410 is formed on the side of the first support member 41 away from the flexible circuit board 13, and a reinforcing member 61, that is, a reinforcing plate, is provided on the side of the adapter 60 away from the flexible circuit board 13. After the second end 1302 of the flexible circuit board 13 is bent toward the first end 1301, the reinforcing member 61 can be located in the groove 410 and connected to the groove 410 to connect the adapter 60 to the first support member 41.

[0131] Exemplarily, the reinforcing member 61 may be connected to the groove 410 by means such as bonding, snap connection, or threaded connection.

[0132] In this way, by connecting the reinforcing member 61 to the groove 410 to connect the adapter 60 to the first support member 41, the first support member 41 and the adapter 60 can stably support the first straight section 131 and the second straight section 132, thereby better maintaining the stability of the bent shape of the flexible circuit board 13. In addition, providing the reinforcing member 61 on the adapter 60 is beneficial to improving the mechanical strength and structural stability of the adapter 60, enabling the adapter 60 to better withstand external stress and vibration, and ensuring that the adapter 60 can work stably and reliably.

[0133] Please refer to Figure 10 and Figure 11 In some other possible embodiments, supporting the first straight section and the second straight section further includes:

[0134] Step S1112: Arrange the second support member between the first end and the second end of the flexible circuit board, and relatively close to the second end of the flexible circuit board with respect to the first support member, and connect the second support member to the flexible circuit board.

[0135] Before the second end 1302 of the flexible circuit board 13 is bent towards the first end 1301, the first support member 41, the second support member 42 and the adapter 60 are all connected and arranged between the first end 1301 and the second end 1302 of the flexible circuit board 13. And along the direction from the second end 1302 to the first end 1301 of the flexible circuit board 13, the adapter 60, the second support member 42 and the first support member 41 are arranged in sequence. After the second end 1302 of the flexible circuit board 13 is bent towards the first end 1301, the adapter 60 is connected to the first support member 41, the top of the second support member 42 contacts the second straight section 132, the first support member 41 and the adapter 60 are away from the bent section 133 relative to the second support member 42, and the second support member 42, the first support member 41 and the adapter 60 cooperate together to support the first straight section 131 and the second straight section 132.

[0136] In this way, by arranging the second support member 42 to support the first straight section 131 and the second straight section 132, the bent section 133 formed after the flexible circuit board 13 is bent is kept in the bent state, so that the flexible circuit board 13 can maintain its shape and stability when bent. At the same time, the second support member 42 can cooperate with the first support member 41 and the adapter 60 to support the first straight section 131 and the second straight section 132, improving the stability of the flexible circuit board 13 in maintaining the bent shape, and can also perform electrical performance tests on the flexible circuit board 13 in the bent state, ensuring that the flexible circuit board 13 can still work stably and reliably after being bent, and guaranteeing the yield rate of the display module 10 during the production process.

[0137] In addition, after the second end 1302 of the flexible circuit board 13 is bent towards the first end 1301, only the first support member 41 and the adapter 60 need to be connected, and it is not necessary to bond the top of the second support member 42 to the second straight section 132, and the second support member 42 can also play a role in supporting the second straight section 132.

[0138] Exemplarily, the second support member 42 can be a foam, a plastic plate, etc.

[0139] Exemplarily, both the first support member 41 and the second support member 42 are bonded to the flexible circuit board 13 through the adhesive layer 50 ( Figure 15 shown in). The adhesive layer 50 between the first support member 41 and the flexible circuit board 13 and the adhesive layer 50 between the second support member 42 and the flexible circuit board 13 can be the same adhesive layer 50. In this way, only one adhesive layer 50 needs to be provided, and the structure is simple and it is convenient for quick disassembly and assembly.

[0140] Figure 12Schematic diagram of the structure after the flexible circuit board 13 and the display substrate 121 are connected. After the second end 1302 of the flexible circuit board 13 is bent toward the first end 1301, the first end 1301 of the flexible circuit board 13 is attached and connected to the display substrate 121 and placed on the workbench of the processing equipment, and the light-transmitting cover plate 11, copper foil, etc. are attached to the display substrate 121 to complete the processing of the display module.

[0141] Please refer to Figure 13 , in some embodiments, the processing method further includes:

[0142] Step S300, bending one end of the display substrate close to the flexible circuit board toward the other end of the display substrate and away from the side where the light-emitting side of the display substrate is located, to obtain a semi-finished display module.

[0143] Step S400, testing the electrical performance of the semi-finished display module.

[0144] Step S500, removing the first support member, the second support member, and the adapter, bending the second end of the flexible circuit board away from the first end of the flexible circuit board, and making the first straight section and the second straight section lie in the same plane, to obtain the display module.

[0145] Please refer to Figure 14 and Figure 15 , a bending portion 1211 is provided at one end of the display substrate 121 close to the flexible circuit board 13. The bending portion 1211 is bent toward the side where the non-light-emitting side of the display substrate 121 is located, to obtain a semi-finished display module 10. The electrical performance of the semi-finished display module 10 is tested, and the adapter 60 is used to connect to the electrical performance testing equipment for testing to ensure that the semi-finished display module has good electrical performance.

[0146] Please refer to Figure 16 , finally, the first support member 41, the second support member 42, and the adapter 60 are removed, and the second end 1302 of the flexible circuit board 13 is restored to the state before bending, to obtain the final display module 10.

[0147] In this way, during the production process of the display module 10, the first support member 41, the second support member 42, and the adapter 60 are used to maintain the stability of the bending form of the flexible circuit board 13 and ensure its good electrical performance, and the adapter 60 is used to ensure the stability of the electrical performance of the display module 10 without removing the first support member 41, the second support member 42, and the adapter 60, thereby ensuring the yield rate of the production of the display module 10.

[0148] Please continue to refer to Figure 16 , the embodiment of the present application further provides a display module 10, and the display module 10 is made by the above-mentioned processing method of the display module.

[0149] The display module 10 is formed by bending the second end 1302 of the flexible circuit board 13 towards the first end 1301 during the processing, so that the total length of the display substrate 121 and the flexible circuit board 13 of the display module 10 adapts to the limit length of the processing equipment. Thus, interference with the processing equipment can be avoided during the processing of the display module 10, and good electrical performance of the display module 10 during the processing is ensured, thereby improving the yield rate of the production of the display module 10.

[0150] An embodiment of the present application further provides an electronic device 100, and the electronic device 100 includes the above-mentioned display module 10. Since the display module 10 of the electronic device 100 is formed by bending the second end 1302 of the flexible circuit board 13 towards the first end 1301 during the processing, the total length of the display substrate 121 and the flexible circuit board 13 of the display module 10 adapts to the limit length of the processing equipment. Thus, interference with the processing equipment can be avoided during the processing of the display module 10, and good electrical performance of the display module 10 during the processing is ensured, thereby improving the yield rate of the production of the display module 10, and further improving the working reliability of the electronic device 100.

[0151] Please refer to Figure 6 , an embodiment of the present application further provides a flexible circuit board assembly, and the flexible circuit board assembly includes a flexible circuit board 13 and an auxiliary support assembly. Among them, the flexible circuit board 13 includes a first straight section 131, a bending section 133, and a second straight section 132 that are connected in sequence. The first straight section 131 and the second straight section 132 are arranged at intervals and are located on the same side of the bending section 133, and the part of the first straight section 131 away from the bending section 133 extends out of the second straight section 132. That is, the first straight section 131 is Figure 6 the part located below as shown in Figure 6 , the second straight section 132 is

[0152] the part located above as shown in

[0153] The flexible circuit board assembly provided by the embodiment of the present application forms a support for the first straight section 131 and the second straight section 132 by arranging an auxiliary support assembly between the first straight section 131 and the second straight section 132, so as to stably keep the bending section 133 in a bent state, and it can avoid the bending section 133 from generating creases or even dead folds, thereby avoiding the circuits and components on the flexible circuit board 13 from being damaged by external impacts or squeezes, and further avoiding the flexible circuit board 13 from being damaged or broken and affecting the electrical performance, so as to ensure the yield rate of the production of the flexible circuit board assembly.

[0154] The flexible circuit board assembly is smaller in length than the flexible circuit board 13. After the flexible circuit board assembly is bonded and connected to the display substrate 121, it can adapt to the limit length of the process equipment, so that the second end 1302 of the flexible circuit board 13 will not interfere with the process equipment during the processing of the display module 10 and affect the electrical performance, which is beneficial to the smooth progress of the processing flow of the display module 10 and ultimately improves the yield rate of the production of the display module 10.

[0155] Exemplarily, the auxiliary support assembly can be connected to the first straight section 131 and the second straight section 132 by means of glue bonding, magnetic attraction connection, etc.

[0156] Please continue to refer to Figure 6 , in some possible embodiments, the auxiliary support assembly is disposed between the first straight section 131 and the second straight section 132, and an adhesive layer 50 ( Figure 15 shown in) is provided between the auxiliary support assembly and the first straight section 131 to bond the auxiliary support assembly and the first straight section 131, and an adhesive layer 50 is provided between the auxiliary support assembly and the second straight section 132 to bond the auxiliary support assembly and the second straight section 132.

[0157] Exemplarily, the adhesive layer 50 can be a reusable adhesive. This adhesive has good adhesion and can firmly bond the auxiliary support assembly and the flexible circuit board 13. At the same time, it also has easy removability and can be easily disassembled without leaving residues or damaging the surfaces of the auxiliary support assembly and the flexible circuit board 13. In addition, this adhesive can be reused, can be pasted and disassembled multiple times, and the viscosity will not decrease significantly.

[0158] In some other possible embodiments, the auxiliary support assembly is disposed between the first straight section 131 and the second straight section 132. A first magnetic attraction portion and a second magnetic attraction portion are provided on the auxiliary support assembly, a third magnetic attraction portion is provided on the first straight section 131, and a fourth magnetic attraction portion is provided on the second straight section 132. Among them, the first magnetic attraction portion can be magnetically connected to the third magnetic attraction portion to connect the auxiliary support assembly and the first straight section 131, and the second magnetic attraction portion can be magnetically connected to the fourth magnetic attraction portion to connect the auxiliary support assembly and the second straight section 132.

[0159] Under the action of an external force, applying a pulling force away from the first straight section 131 to the second straight section 132 can separate the second straight section 132 from the auxiliary support assembly, and applying a pulling force away from the second straight section 132 to the first straight section 131 can separate the first straight section 131 from the auxiliary support assembly.

[0160] It can be understood that, without causing electromagnetic interference to the flexible circuit board 13, by adjusting the strength and position of the first magnetic attraction part, the second magnetic attraction part, the third magnetic attraction part, and the fourth magnetic attraction part, the connection stability between the auxiliary support component and the flexible circuit board 13 can be achieved.

[0161] In some embodiments, the inner diameter of the bending section 133 is greater than or equal to 1.4 mm. In this embodiment, the inner diameter of the bending section 133 can be set to 1.6 mm.

[0162] In this way, by keeping the inner diameter of the bending section 133 at a value greater than or equal to 1.4 mm, it is possible to avoid creases or even dead folds in the bending section 133, thereby ensuring the bending shape of the bending section 133 and the working reliability of the flexible circuit board 13.

[0163] Exemplarily, the height of the auxiliary support component can be set according to the inner diameter of the bending section 133, as long as the bending section 133 is stable in the bent state without creases or even dead folds. In this embodiment, the distance between the top surface of the second straight section 132 and the bottom surface of the first straight section 131 does not exceed 2 mm, and can be set to 1.4 mm, for example. With such a setting, it is possible to ensure that the bending section 133 is stably maintained in the bent shape.

[0164] Please continue to refer to Figure 6 , in some possible embodiments, the auxiliary support component includes a first support member 41, and the first support member 41 is the Figure 6 support structure 40 shown in

[0165] The first support member 41 is disposed between the first straight section 131 and the second straight section 132. The first support member 41 is used to support the first straight section 131 and the second straight section 132 and is connected to the first straight section 131 and the second straight section 132.

[0166] In this way, by providing the first support member 41 to support the first straight section 131 and the second straight section 132, the bending section 133 is stabilized in the bent state, which can avoid creases or even dead folds in the bending section 133, thereby preventing the circuits and components on the flexible circuit board 13 from being damaged by external impacts or squeezes, and further preventing the flexible circuit board 13 from being damaged or broken and affecting the electrical performance.

[0167] Exemplarily, the first support member 41 can be a foam, a plastic plate, etc.

[0168] Exemplarily, the first support member 41 can be adhesively bonded to the first straight section 131 and the second straight section 132 respectively through an adhesive layer 50.

[0169] Please refer to Figure 9 , in some possible embodiments, the flexible circuit board assembly further includes an adapter 60. The adapter 60 is disposed between the second straight section 132 and the first support member 41 and connects the second straight section 132 and the first support member 41. The adapter 60 is used to connect an electrical performance testing device.

[0170] The adapter 60 is a connecting wire made of a flexible circuit board 13, usually composed of one or more thin film circuit boards. The adapter 60 is used for signal transmission and power supply between each circuit board and each component in the electronic device 100. A test interface is provided on the adapter 60, which can be connected to an electrical performance testing device. By using the adapter 60 to connect the flexible circuit board 13 and the electrical performance testing device, the electrical performance of the flexible circuit board 13 can be tested.

[0171] In this way, by electrically connecting the flexible circuit board 13 and the adapter 60, it can be verified whether the electrical performance of the flexible circuit board 13 meets the design requirements, so as to ensure that the flexible circuit board 13 can still work stably and reliably after being bent, and ensure the yield rate of the production of the flexible circuit board assembly. Exemplarily, the electrical performance testing device can be an oscilloscope, a signal generator, a voltmeter, an ammeter, etc.

[0172] In addition, by providing the adapter 60 and the first support member 41 to support the first straight section 131 and the second straight section 132, the bent section 133 formed after the flexible circuit board 13 is bent is maintained in a bent state, so that the flexible circuit board 13 can maintain its shape and stability when bent. In addition, the first support member 41 can also support the adapter 60, improving the compactness of the entire structure. The adapter 60 can also be used to test the electrical performance of the bent flexible circuit board 13, ensuring that the flexible circuit board 13 can still work stably and reliably after being bent, and ensuring the yield rate of the production of the flexible circuit board assembly.

[0173] Exemplarily, the material of the above-mentioned first support member 41 can be a material with relatively high strength such as ceramic or plastic.

[0174] Exemplarily, the first support member 41 can be connected to the adapter 60 by means of bonding, screw connection, etc.

[0175] In some embodiments, the flexible circuit board 13 and the adapter 60 can be physically and electrically connected through a board-to-board connector or a flexible electrical connector. A board-to-board connector is provided on the side of the second straight section 132 facing the adapter 60, and a corresponding board-to-board connector is provided on the side of the adapter 60 facing the second straight section 132. The board-to-board connector on the flexible circuit board 13 and the board-to-board connector on the adapter 60 are buckled to connect the flexible circuit board 13 and the adapter 60.

[0176] Understandably, a reinforcing plate 134 is provided on one side of the second straight section 132 away from the adapter 60, and a reinforcing member 61 is provided on one side of the adapter 60 away from the second straight section 132, which can enhance the mechanical strength and stability of the board-to-board connector, thereby reducing the displacement and deformation of the connector, and improving the durability and reliability of the connector.

[0177] Exemplarily, the reinforcing plate 134 and the reinforcing member 61 can be connected to the flexible circuit board 13 and the adapter 60 respectively by means of threaded connection, adhesive bonding, etc.

[0178] Exemplarily, the materials of the reinforcing plate 134 and the reinforcing member 61 can be materials such as aluminum alloy, stainless steel, polymer composite material, etc. with high strength and rigidity, which can provide good support and protection.

[0179] Please continue to refer to Figure 9 , in some possible embodiments, a groove 410 is formed on one side of the first support member 41 facing the adapter 60, a reinforcing member 61 is provided on one side of the adapter 60 facing the first support member 41, and the reinforcing member 61 is connected to the groove 410.

[0180] In this way, by connecting the reinforcing member 61 to the groove 410 to connect the adapter 60 and the first support member 41, the first support member 41 and the adapter 60 can stably support the first straight section 131 and the second straight section 132, so that the bent section 133 formed after the flexible circuit board 13 is bent remains in the bent state, thereby better maintaining the stability of the bent shape of the flexible circuit board 13. In addition, providing the reinforcing member 61 on the adapter 60 is beneficial to improving the mechanical strength and structural stability of the adapter 60, enabling the adapter 60 to better withstand external stress and vibration, and ensuring that the adapter 60 can work stably and reliably.

[0181] Exemplarily, the reinforcing member 61 can be connected to the groove 410 by means of adhesive bonding, snap connection, threaded connection, etc.

[0182] Please refer to Figure 11 , in some possible embodiments, the auxiliary support assembly further includes a second support member 42, the second support member 42 is disposed between the first straight section 131 and the second straight section 132, and is connected to the first straight section 131, and the second support member 42 is disposed on one side of the first support member 41 close to the bent section 133.

[0183] In some embodiments, the second support member 42 is connected to at least one of the first straight section 131 and the second straight section 132, that is, the second support member 42 is connected to the first straight section 131, or the second support member 42 is connected to the second straight section 132, or alternatively, the second support member 42 is connected to both the first straight section 131 and the second straight section 132.

[0184] In this way, by arranging the second support member 42 to support the first straight section 131 and the second straight section 132, the bent section 133 formed after the flexible circuit board 13 is bent is maintained in a bent state, so that the flexible circuit board 13 can maintain its shape and stability when bent. At the same time, the second support member 42 can cooperate with the first support member 41 and the adapter 60 to support the first straight section 131 and the second straight section 132, improving the stability of the flexible circuit board 13 in maintaining the bent shape, and can also perform electrical performance tests on the flexible circuit board 13 in the bent state to ensure that the flexible circuit board 13 can still work stably and reliably after being bent, ensuring the yield rate of the production of the flexible circuit board assembly.

[0185] In addition, after the second end 1302 of the flexible circuit board 13 is bent towards the first end 1301, only the first support member 41 and the adapter 60 need to be connected, without bonding the top of the second support member 42 to the second straight section 132, or without bonding the bottom of the second support member 42 to the first straight section 131, and the second support member 42 can also play a role in supporting the second straight section 132.

[0186] Exemplarily, the second support member 42 can be a foam, a plastic plate, etc.

[0187] In some possible embodiments, the first support member 41 and the flexible circuit board 13 are bonded through an adhesive layer 50. The second support member 42 and the flexible circuit board 13 are also bonded through the adhesive layer 50.

[0188] In this way, the first support member 41, the second support member 42 and the flexible circuit board 13 are bonded through the adhesive layer 50, making the first support member 41 and the second support member 42 easy to disassemble and assemble, and there is no need to structurally modify the flexible circuit board 13 itself, thus maintaining the structural integrity of the flexible circuit board 13.

[0189] Exemplarily, please refer to Figure 15 , the adhesive layer 50 between the first support member 41 and the flexible circuit board 13 and the adhesive layer 50 between the second support member 42 and the flexible circuit board 13 can be the same adhesive layer 50. In this way, only one adhesive layer 50 needs to be provided, with a simple structure and convenient for quick disassembly and assembly.

[0190] Please refer to Figure 14 and Figure 15 , the embodiment of the present application also provides a display module assembly, and the display module assembly includes a display substrate 121 and the above flexible circuit board assembly. Among them, the display substrate 121 includes a bent portion 1211. Along the direction perpendicular to the plane where the display substrate 121 is located, the first straight section 131 is spaced apart from the display substrate 121, and one end of the first straight section 131 away from the bent section 133 is connected to the bent portion 1211.

[0191] In the display module component provided by the embodiment of the present application, a bending portion 1211 is provided at one end of the display substrate 121 close to the flexible circuit board 13, and the bending portion 1211 is bent toward the side where the non-light-emitting side of the display substrate 121 is located to obtain the display module component.

[0192] In the display module component provided by the embodiment of the present application, the auxiliary support component and the adapter 60 are used to maintain the stability of the bending form of the flexible circuit board component and ensure its good electrical performance. The flexible circuit board component is smaller in length than the flexible circuit board 13. After the flexible circuit board component is attached to the display substrate 121, it can adapt to the limit length of the processing equipment, so that the second end 1302 of the flexible circuit board 13 will not interfere with the processing equipment during the processing of the display module 10, which is beneficial to the smooth progress of the processing flow of the display module component. Finally, the adapter 60 is used to ensure the stability of the electrical performance of the display module component, thereby ensuring the yield rate of the production of the display module component, and further ensuring the yield rate of the production of the display module 10.
