[0082] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0083] In some embodiments, the display module includes a housing, a display panel, and a flexible circuit board. The housing has a receiving cavity. The display panel includes a first portion and a second portion. The flexible circuit board includes a driving circuit, and the flexible circuit board can be bonded to the second portion, thereby enabling the driving circuit on the flexible circuit board to provide driving signals to the display panel. During the fabrication of the display module, the first portion of the display panel is fixed within the receiving cavity of the housing, and the second portion of the display panel extends beyond the housing design and forms a certain angle with the first portion. The flexible circuit board and the second portion are then fixedly connected. After a series of related processes, the second portion is finally bent to one side of the first portion, thereby achieving the bonding connection between the flexible circuit board and the display panel.

[0084] However, after the flexible circuit board and the second part of the display panel are fixedly connected, but before the flexible circuit board and the second part of the display panel are bonded together, the shaking of the flexible circuit board can easily cause cracks at the junction of the first part and the second part of the display panel, which in turn leads to a low yield of the display module.

[0085] This application provides a locking component 104 that can be applied to a display module. For example, the locking component 104 can be applied during the manufacturing process of the display module, where the display module does not include the locking component 104. Alternatively, the locking component 104 can not only be applied during the manufacturing process of the display module, but the display module can also include at least a portion of the locking component 104.

[0086] Figure 1 is a partial structural schematic diagram of a locking component 104 applied to a display module according to an embodiment of this application. Referring to Figure 1, the display module 100 includes: a housing assembly 101, a display panel 102, and a flexible printed circuit (FPC) 103. The housing assembly 101 can be a cover glass (CG) assembly, and the housing assembly 101 has a receiving cavity 101a. The display panel 102 includes a first panel portion 1021, a bent portion 1022, and a second panel portion 1023. The first panel portion 1021 and the bent portion 1022 are located within the receiving cavity 101a, and the bent portion 1022 is closer to the edge of the receiving cavity 101a than the first panel portion 1021. The second panel portion 1023 is connected to the first panel portion 1021 through the bent portion 1022. The flexible printed circuit 103 can be connected to the second panel portion 1023.

[0087] Optionally, the second panel portion 1023 and the first panel portion 1021 can have a certain angle through the bending portion 1022. For example, during the manufacturing process of the display module 100, after the display panel 102 and the housing assembly 101 are assembled (the assembly of the display panel 102 and the housing assembly 101 can be referred to as D-Lami assembly), the bending portion 1022 can be bent so that the angle between the second panel portion 1023 and the first panel portion 1021 is approximately 90 degrees; after the flexible circuit board 103 (FPC) and the display panel 102 (panel) are bonded together, that is, after the second panel portion 1023 of the display panel 102 needs to drive the flexible circuit board 103 to bend to the back side of the first panel portion 1021, the angle between the second panel portion 1023 and the first panel portion 1021 is approximately 180 degrees.

[0088] Figure 2 is a schematic diagram of a locking component 104 provided in an embodiment of this application. Referring to Figure 2, the locking component 104 includes a first locking part 1041 and a second locking part 1042. Combining Figures 1 and 2, the first locking part 1041 is used for fixed connection with the second panel portion 1023 or the flexible circuit board 103. Figure 1 illustrates an example of the first locking part 1041 and the second panel portion 1023 being fixedly connected. Furthermore, the second locking part 1042 is rotatable relative to the first locking part 1041.

[0089] During the fabrication of the display module 100, after assembling the display panel 102 and the housing assembly 101, the first panel portion 1021 of the display panel 102 is located within the receiving cavity 101a of the housing assembly 101. The bent portion 1022 is closer to the edge of the receiving cavity 101a than the first panel portion 1021. The second panel portion 1023 extends out of the receiving cavity 101a from its edge and can be located outside the receiving cavity 101a. Subsequently, the flexible circuit board 103 and the second panel portion 1023 can be fixedly connected. In this case, the flexible circuit board 103 is also located outside the receiving cavity 101a, suspended on one side of the receiving cavity 101a relative to the housing assembly 101. After further processing (which may require handling the prepared module), the second panel portion 1023 can be bent via the bending portion 1022 to the side of the first panel portion 1021 away from the housing assembly 101, so that the flexible circuit board 103 is located on the side of the second panel portion 1023 away from the housing assembly 101. In this case, at least a portion of the flexible circuit board 103 is also located within the receiving cavity 101a, achieving a bonding connection between the flexible circuit board 103 and the second panel portion 1023 of the display panel 102.

[0090] In some embodiments, after the flexible circuit board 103 and the display panel 102 are fixedly connected, and before they are bonded together, the prepared module portion needs to be transported. Since the flexible circuit board 103 has a certain weight, it will shake during transport, which can cause excessive stress on the bent portion 1022 of the display panel 102, leading to cracks in the bent portion 1022 and affecting the yield of the display module 100.

[0091] In this embodiment, after the flexible circuit board 103 and the display panel 102 are fixedly connected, and before they are bonded together (i.e., when the second panel portion 1023 is outside the receiving cavity 101a), the second locking portion 1042 is also used to fixally connect to the housing assembly 101. Thus, even if the flexible circuit board 103 shakes, the presence of the locking portion 1042 can indirectly fix the flexible circuit board 103 to the housing assembly 101, providing some support for the flexible circuit board 103. Therefore, on the one hand, the shaking amplitude of the flexible circuit board 103 can be reduced, and on the other hand, the force exerted by the shaking on the bent portion 1022 of the display panel 102 can be reduced, thereby reducing the impact of the shaking on the bent portion 1022, preventing cracks in the bent portion 1022, and improving the yield of the display module.

[0092] Furthermore, in order to achieve the bonding connection between the flexible circuit board 103 and the display panel 102, the fixed connection between the second locking part 1042 and the housing assembly 101 must be released before the bonding connection is established. That is, the second locking part 1042 and the housing assembly 101 are in a free state.

[0093] It should be noted that if it is necessary for the final display module 100 to not include the locking component 104, the fixed connection between the first locking part 1041 and the second panel part 1023 can be released. That is, the locking component 104 can be directly removed from the display module 100.

[0094] If the final display module 100 needs to include at least a portion of the locking assembly 104, then it is not necessary to release the fixed connection between the first locking part 1041 and the second panel part 1023. In this case, referring to FIG3, during the process of the second panel part 1023 being gradually bent to the side of the first panel part 1021 away from the housing assembly 101 via the bending part 1022 (i.e., during the bonding connection of the flexible circuit board 103 and the display panel 102), the second locking part 1042 can rotate relative to the first locking part 1041. When the second panel part 1023 is bent and disposed on the side of the first panel part 1021 away from the housing assembly 101 via the bending part 1022, and is located within the receiving cavity 101a (i.e., after the bonding connection of the flexible circuit board 103 and the display panel 102 is completed), the second locking part 1042 can be located on the side of the second panel part 1023 away from the first panel part 1021. That is, due to the relative rotation of the second locking part 1042 and the first locking part 1041, the second locking part 1042 can be fastened to the side of the second panel part 1023 away from the first panel part 1021.

[0095] In this embodiment, the second locking part 1042 is fastened to the side of the second panel portion 1023 away from the first panel portion 1021, which can protect the devices at relevant positions on the second panel portion 1023. That is, the design of the locking component 104 can not only support the flexible circuit board 103 during the manufacturing process of the display module 100, but also protect the devices on the display panel 102.

[0096] In summary, this application provides a locking component applied in a display module. The display module includes a housing assembly, a display panel, and a flexible circuit board. After the flexible circuit board and the second panel portion of the display panel are fixedly connected, and both the flexible circuit board and the second panel portion are located outside the receiving cavity, the locking component can be fixedly connected to the housing assembly of the display module. The presence of the locking component can relatively fix the flexible circuit board and the housing assembly, reduce the shaking amplitude of the flexible circuit board, and reduce the force exerted by the shaking of the flexible circuit board on the bent portion of the display panel, preventing cracks from forming in the bent portion and improving the yield of the display module.

[0097] Figure 4 is a structural schematic diagram of a display module provided in an embodiment of this application. Figure 5 is a partial schematic diagram of region A in Figure 4. Referring to Figures 4 and 5, the housing assembly 101 includes a first housing portion 1011 and a second housing portion 1012. The second housing portion 1012 has an annular structure and is connected to the edge of the first housing portion 1011. The first housing portion 1011 and the second housing portion 1012 constitute a receiving cavity 101a. For example, the first housing portion 1011 and the second housing portion 1012 are an integral structure and constitute a cavity-type housing assembly 101.

[0098] Referring to Figure 4, after the flexible circuit board 103 and the display panel 102 are fixedly connected, and before the flexible circuit board 103 and the display panel 102 are bonded together (i.e., when the second panel portion 1023 is outside the receiving cavity 101a), the second locking portion 1042 is located on the side of the second housing portion 1012 away from the first housing portion 1011, and the orthographic projection of the second locking portion 1042 on the housing assembly 101 overlaps with the second housing portion 1012. As shown in Figure 5, in order to achieve the fixed connection between the locking assembly 104 and the housing assembly 101, a first adhesive n1 can be provided between the second locking portion 1042 and the second housing portion 1012. The surface of the second locking portion 1042 near the second housing portion 1012 is bonded to the side of the second housing portion 1012 away from the first housing portion 1011 by the first adhesive n1. That is, the second locking portion 1042 and the second housing portion 1012 are respectively configured to be bonded to two different surfaces of the first adhesive n1.

[0099] Optionally, the first adhesive n1 (tape adhesive) can be a weak adhesive. Weak adhesive refers to temporary adhesive that is easy to remove later. The adhesion of the first adhesive n1 can be comparable to that of a common protective film, ranging from 10 gf / inch to 20 gf / inch. Before bonding the flexible circuit board 103 and the display panel 102, the fixing connection between the second locking part 1042 and the second housing part 1012 can be released, and the first adhesive n1 on the surfaces of the second locking part 1042 and the second housing part 1012 can be peeled off. Then, during the bonding process between the flexible circuit board 103 and the display panel 102, the second locking part 1042 rotates towards the side closer to the first locking part 1041, thereby causing the second locking part 1042 to engage with the side of the second panel part 1023 away from the first panel part 1021.

[0100] Referring to Figures 6 and 7, after the flexible circuit board 103 and the display panel 102 are fixedly connected, and before the flexible circuit board 103 and the display panel 102 are bonded together (i.e., when the second panel portion 1023 is outside the receiving cavity 101a), the second locking portion 1042 is located on the side of the second housing portion 1012 away from the first housing portion 1011. To achieve the fixed connection between the locking assembly 104 and the housing assembly 101, a first adhesive n1 can be provided on the end face of the second locking portion 1042 away from the first locking portion 1041 and on the surface of the second housing portion 1012 away from the receiving cavity 101a. That is, the end face of the second locking portion 1042 away from the first locking portion 1041 and the surface of the second housing portion 1012 away from the receiving cavity 101a are both configured to be bonded to the first adhesive n1, thereby enabling the second locking portion 1042 and the second housing portion 1012 to be fixedly connected by the first adhesive n1.

[0101] Optionally, the first adhesive n1 includes a first adhesive portion n11 and a second adhesive portion n12, which are integrally formed. The first adhesive portion n11 is configured to be located on the end face of the second locking portion 1042 away from the first locking portion 1041, and the first adhesive portion n11 is configured to bond to the end face of the second locking portion 1042 away from the first locking portion 1041. The second adhesive portion n12 is configured to be located on the surface of the second housing portion 1012 away from the receiving cavity 101a, and the second adhesive portion n12 is configured to bond to the surface of the second housing portion 1012 away from the receiving cavity 101a. That is, the second locking portion 1042 and the second housing portion 1012 are both configured to be bonded to different areas of the same surface of the first adhesive n1.

[0102] Optionally, the first adhesive n1 can be a weak adhesive. Before bonding the flexible circuit board 103 and the display panel 102, the first adhesive n1 bonded to the second locking part 1042 and the second housing part 1012 can be removed, thereby releasing the fixed connection between the second locking part 1042 and the second housing part 1012. Subsequently, during the bonding process between the flexible circuit board 103 and the display panel 102, the second locking part 1042 rotates towards the side closer to the first locking part 1041, thereby causing the second locking part 1042 to engage with the side of the second panel part 1023 away from the first panel part 1021.

[0103] Referring to Figures 1, 2, and 8, the locking assembly 104 further includes a third locking portion 1043. The third locking portion 1043 can be fixedly connected to the surface of the second locking portion 1042 away from the surface of the first locking portion 1041. For example, the third locking portion 1043 can be an integral structure with the second locking portion 1042.

[0104] After the flexible circuit board 103 and the display panel 102 are fixedly connected, and before the flexible circuit board 103 and the display panel 102 are bonded together (i.e., when the second panel portion 1023 is outside the receiving cavity 101a), the second locking portion 1042 is located on the side of the second housing portion 1012 away from the first housing portion 1011, and the third locking portion 1043 is located on the side of the second housing portion 1012 away from the receiving cavity 101a. To achieve the fixed connection between the locking assembly 104 and the housing assembly 101, a first adhesive n1 can be provided between the third locking portion 1043 and the second housing portion 1012, and the third locking portion 1043 and the second housing portion 1012 are configured to be bonded by the first adhesive n1. That is, the third locking portion 1043 and the second housing portion 1012 are respectively configured to be bonded to two different surfaces of the first adhesive n1.

[0105] Optionally, the first adhesive n1 can be a weak adhesive. Before the flexible circuit board 103 and the display panel 102 are bonded together, the fixing connection between the third locking part 1043 and the second housing part 1012 can be released, and the first adhesive n1 on the surfaces of the third locking part 1043 and the second housing part 1012 can be peeled off. Then, during the bonding process between the flexible circuit board 103 and the display panel 102, the second locking part 1042 drives the third locking part 1043 to rotate towards the side closer to the first locking part 1041, thereby causing the second locking part 1042 to engage with the side of the second panel part 1023 away from the first panel part 1021.

[0106] Figure 9 is an exploded view of a locking assembly provided in an embodiment of this application. Referring to Figure 9, the locking assembly 104 further includes a support portion 1044. The support portion 1044 may include an annular first support structure 10441 and a second support structure 10442 fixedly connected to the first support structure 10441.

[0107] Referring to Figures 10 and 11, after the flexible circuit board 103 and the display panel 102 are fixedly connected, and before the flexible circuit board 103 and the display panel 102 are bonded together (i.e., when the second panel portion 1023 is outside the receiving cavity 101a), a first support structure 10441 is configured to be disposed on the side of the housing assembly 101 away from the display panel 102. The first support structure 10441 is configured to surround the housing assembly 101 and sleeve the edge of the housing assembly 101, and is fixedly connected to the edge of the housing assembly 101. The first support structure 10441 is configured to support the housing assembly 101, the display panel 102, and the flexible circuit board 103. The second support structure 10442 has a fixing groove 10442a (which can be a through groove), and a second locking part 1042 is configured to be located within the fixing groove 10442a and fixedly connected to the second support structure 10442. Furthermore, the second support structure 10442 is configured such that its orthographic projection on the flexible circuit board 103 is located within the flexible circuit board 103.

[0108] Optionally, the shape of the first support structure 10441 of the support portion 1044 can match the shape of the housing assembly 101, and the first support structure 10441 can also be called a simulated housing assembly structure. Through the design of the support portion 1044, the support performance of the locking assembly 104 on the flexible circuit board 103 can be further improved. Therefore, during the fabrication of the display module 100, the locking assembly 104 can provide better support for the flexible circuit board 103, reducing the impact of the flexible circuit board 103's swaying on the bent portion 1022.

[0109] Since the support portion 1044 is a shell-like assembly structure, it may affect the appearance of the display module 100, resulting in a wider bezel. Therefore, before the flexible circuit board 103 and the display panel 102 are bonded together, the support portion 1044 can be removed, leaving only the locking portions of the locking assembly 104 (i.e., the display module does not include the support portion 1044 in the locking assembly 104, but only the locking portions in the locking assembly 104). Then, during the bonding process between the flexible circuit board 103 and the display panel 102, the second locking portion 1042 rotates towards the side closer to the first locking portion 1041, thereby causing the second locking portion 1042 to engage with the side of the second panel portion 1023 away from the first panel portion 1021.

[0110] In this embodiment, the first support structure 10441 and the housing assembly 101 are configured to be bonded by a weak adhesive, or the first support structure 10441 and the housing assembly 101 are configured to be connected by a snap-fit.

[0111] Optionally, the support portion 1044 of the locking assembly 104 further includes a fastening collar 10443. The fastening collar 10443 is configured to be located between the first support structure 10441 and the housing assembly 101. The fastening collar 10443 is configured to secure the connection between the first support structure 10441 and the housing assembly 101, and to prevent impact from the first support structure 10441 onto the housing assembly 101. For example, the fastening collar 10443 may be made of foam or rubber.

[0112] Optionally, the first support structure 10441 and the second support structure 10442 of the support portion 1044 can be plastic injection molded parts or metal sheet metal parts, and this application embodiment does not limit them.

[0113] In this embodiment of the application, referring to Figures 1 to 11, the display panel 102 further includes a driver chip (driver IC) 1024. The driver chip 1024 is fixedly connected to the second panel portion 1023. For example, the driver chip 1024 is disposed on the surface of the second panel portion 1023 away from the receiving cavity 101a. After the second locking part 1042 rotates closer to the first locking part 1041, the orthographic projection of the second locking part 1042 on the second panel portion 1023 can cover the driver chip 1024, thereby enabling the second locking part 1042 to protect the driver chip 1024.

[0114] Optionally, the second locking part 1042 includes a second main body portion 10421 and an annular protrusion structure 10422 located on one side of the second main body portion 10421. The second main body portion 10421 and the annular protrusion structure 10422 constitute a receiving groove 1042a.

[0115] After the flexible circuit board 103 and the display panel 102 are bonded together, i.e., the second panel portion 1023 is positioned on the side of the first panel portion 1021 away from the housing assembly 101 via the bent portion 1022, and the second panel portion 1023 is located within the receiving cavity 101a, the receiving groove 1042a can be used to receive the driver chip 1024. For example, the annular protrusion structure 10422 surrounds the driver chip 1024, and the second main body portion 10421 is located on the side of the driver chip 1024 away from the second panel portion 1023. In this case, it can be ensured that the driver chip 1024 is enclosed within the receiving groove 1042a of the second panel portion 1023, preventing other devices from affecting the driver chip 1024.

[0116] Furthermore, referring to FIG12, the second locking portion 1042 may further include a protective layer 10423. The protective layer 10423 may be located in the area surrounded by the annular protrusion structure 10422, and the protective layer 10423 is connected to the second main body portion 10421. For example, the protective layer 10423 may be located on the surface of the second main body portion 10421 in the area surrounded by the annular protrusion structure 10422.

[0117] Optionally, the protective layer 10423 can be made of one of the following materials: copper foil, aluminum foil, microwave absorbing material, semi-conductive material, or foam. Different materials used in the protective layer 10423 can provide different effects. Of course, various protective effects can also be achieved through other methods.

[0118] For example, electromagnetic interference (EMI) protection can be implemented in the following ways: 1. The second main body 10421 and the annular protrusion structure 10422 are made of metallic materials. 2. The protective layer 10423 is made of a wave-absorbing material, or the outer surface of the second locking part 1042 can also be made of a wave-absorbing material. 3. The wall thickness of the annular protrusion structure 10422 can be different at different locations. For example, the wall thickness on the side closer to the flexible circuit board 103 (which contains capacitors and inductors) can be larger, and the wall thickness on the side farther from the flexible circuit board 103 can be smaller. For example, the annular protrusion structure 10422 includes a first protrusion portion and a second protrusion portion, with the first protrusion portion closer to the flexible circuit board 103 than the second protrusion portion. The wall thickness of the first protrusion portion is greater than the wall thickness of the second protrusion portion. The wall thickness of the second protrusion can be equal to 0, that is, the annular protrusion structure 10422 is a non-closed protrusion structure, and the side of the annular protrusion structure 10422 away from the flexible circuit board 103 can be an opening.

[0119] The electrostatic discharge (ESD) protection is implemented as follows: 1. The second main body 10421 and the annular protrusion structure 10422 are made of semi-conductive materials, such as polycarbonate (PC), acrylonitrile butadiene styrene (ABS), and polyethylene glycol terephthalate (PET), with a resistance value ranging from 10⁴ Ω to 10⁹ Ω. 2. A grounding contact is provided in the receiving groove 1042a, and the grounding contact is connected to the exposed copper grounding area of ​​the flexible circuit board 103 via a lead wire. 3. The protective layer 10423 is made of copper foil.

[0120] The buffer protection is achieved by using foam as the material for the protective layer 10423. The foam can prevent the driver chip 1024 from developing internal stress cracks when subjected to thermal shock, as well as external damage cracks caused by external pressure, impact, and scraping. It can also limit the high heat absorption of the driver chip 1024 due to thermal expansion and contraction.

[0121] The heat absorption protection methods include: 1. Designing a thicker wall for the annular protrusion 10422, for example, the wall thickness of the annular protrusion 10422 ranges from 0.5 mm to 2 mm. 2. The materials for the second main body 10421 and the annular protrusion 10422 can be copper foil or aluminum foil with good thermal conductivity. 3. The material for the protective layer 10423 is copper foil or aluminum foil with good thermal conductivity.

[0122] In this embodiment, referring to FIG2, the second locking part 1042 further includes a second adhesive 10424. The second adhesive 10424 is located in the area surrounded by the annular protrusion structure 10422. One side of the second adhesive 10424 is bonded to the surface of the second main body part 10421, and the other side of the second adhesive 10424 is used to bond to the surface of the driver chip 1024 away from the second panel part 1023. Thus, after the second locking part 1042 rotates towards the first locking part 1041, even when the driver chip 1024 is wrapped in the receiving groove 1042a, the side of the driver chip 1024 away from the second panel part 1023 can be bonded to the second adhesive 10424 in the receiving groove 1042a, thereby ensuring the connection reliability of the locking assembly 104 and the display panel 102. The second adhesive 10424 can be referred to as the protective adhesive (IC cover tape) for the driver chip.

[0123] Optionally, when the locking assembly 104 includes both a protective layer 10423 and a second adhesive 10424, the protective layer 10423 may be disposed between the second adhesive 10424 and the second main body portion 10421, with both sides of the second adhesive 10424 bonded to the protective layer 10423 and the driving chip 1024, respectively. Alternatively, the second adhesive 10424 may be disposed between the protective layer 10423 and the second main body portion 10421, with both sides of the second adhesive 10424 bonded to both the protective layer 10423 and the second main body portion 10421, respectively.

[0124] In this embodiment, referring to FIG13, the first locking part 1041 can be a Mylar sheet with both adhesiveness and flexibility. The adhesiveness is used to achieve bonding, and the flexibility is used to achieve bending. Optionally, the adhesiveness of the Mylar sheet 1041 can refer to single-sided adhesiveness (single-sided adhesive) or double-sided adhesiveness (double-sided adhesive); this embodiment does not specifically limit this.

[0125] Referring to Figures 1 and 13, the Mylar sheet 1041 is used to bond the second panel portion 1023. The flexibility of the Mylar sheet 1041 facilitates bending so that the second locking portion 1042 can rotate relative to the first locking portion 1041.

[0126] Optionally, referring to FIG13, at least a portion of the first locking portion 1041 is located on the side of the second locking portion 1042 away from the display panel 102, and the first locking portion 1041 and the second locking portion 1042 are bonded to the side away from the display panel 102. In this case, the area of ​​the surface of the second main body portion 10421 without the annular protrusion structure 10422 near the first locking portion 1041 is the bonding area 1042b. At least a portion of the first locking portion 1041 and the annular protrusion structure 10422 of the second locking portion 1042 are located on different sides of the second main body portion 10421, and the first locking portion 1041 can be bonded to the bonding area 1042b of the second main body portion 10421.

[0127] Alternatively, referring to FIG12, the first locking part 1041 is located between the second locking part 1042 and the display panel 102, and the first locking part 1041 and the second locking part 1042 are bonded to the side of the display panel 102. In this case, the area of ​​the surface of the second main body portion 10421 where the annular protrusion structure 10422 is provided, near the first locking part 1041, is the bonding area 1042b. At least a portion of the first locking part 1041 and the annular protrusion structure 10422 of the second locking part 1042 are located on the same side of the second main body portion 10421, and the first locking part 1041 can be bonded to the bonding area 1042b of the second main body portion 10421.

[0128] That is, when the first locking part 1041 is a Mylar sheet, a portion of the Mylar sheet is adhered to the surface of the second panel portion 1023, and another portion is adhered to the surface of the second locking part 1042. In the locking assembly 104 shown in FIG. 13, the first locking part 1041 (Mylar sheet) can be double-sided adhesive. In the locking assembly 104 shown in FIG. 12, the first locking part 1041 (Mylar sheet) can be single-sided adhesive.

[0129] Referring to Figure 14, the second locking part 1042 has at least one connecting structure 10424 at one end near the first locking part 1041 (Figure 14 illustrates three connecting structures 10424). Each connecting structure 10424 has a through hole. The second locking part 1042 of the locking assembly 104 also includes a rotating shaft 10425, which can be located within the through hole of the connecting structure 10424 and can rotate about the axis of the through hole. Furthermore, both ends of the rotating shaft 10425 can be fixedly connected to the first locking part 1041. Thus, during the bonding connection between the flexible circuit board 103 and the display module 100, the second locking part 1042 and the first locking part 1041 rotate based on the rotating shaft 10425.

[0130] Referring to Figure 14, the first locking part 1041 includes a first main body part 10411 and two fixing parts 10412. The two fixing parts 10412 are side-connected to the first main body part 10411, and there is a gap G between the two fixing parts 10412. A rotating shaft 10425 and at least one connecting structure 10424 may be located within the gap G. Both fixing parts 10412 have fixing holes. One end of the rotating shaft 10425 is connected to the fixing hole of one fixing part 10412, and the other end of the rotating shaft 10425 passes through the through hole of the connecting structure 10424 and is connected to the fixing hole of the other fixing part 10412.

[0131] In the scheme shown in Figure 14, the design of the rotating shaft 10425 allows the second locking part 1042 and the first locking part 1041 to rotate relative to each other. Furthermore, the first locking part 1041 can be adhered to the surface of the second panel portion 1023 using adhesive. Optionally, in the scheme where rotation is achieved via the rotating shaft 10425, at least one material selected from ABS, PC, and silicone can be used, and the second locking part 1042 can be obtained using an injection molding process.

[0132] In this embodiment, the first locking part 1041 can be connected to the second panel part 1023 or to the flexible circuit board 103. Furthermore, the manufacturing process of the display module 100 can differ depending on the connection method.

[0133] Optionally, if the first locking part 1041 and the second panel part 1023 are connected, the manufacturing process of the display module includes: assembling the display panel 102 and the housing assembly 101; fixing the flexible circuit board 103 and the second panel part 1023 of the display panel 102 (i.e., the flexible circuit board 103 is suspended relative to the housing assembly 101); fixing the first locking part 1041 and the second panel part 1023 of the locking assembly 104, and fixing the second locking part 1042 of the locking assembly 104 and the housing assembly 101; transferring the components within the factory for other series of processes; releasing the connection between the second locking part 1042 and the housing assembly 101; binding the flexible circuit board 103 and the display panel 102 together, while the second locking part 1042 rotates relative to the first locking part 1041 and latches onto the driver chip 1024 (which can be referred to as the locking structure and the driver chip 1024 being bound together), so that the second locking part 1042 protects the driver chip 1024.

[0134] If the first locking part 1041 and the flexible circuit board 103 are connected, the manufacturing process of the display module includes: assembling the display panel 102 and the housing assembly 101; fixing the first locking part 1041 and the flexible circuit board 103; fixing the flexible circuit board 103 and the second panel portion 1023 of the display panel 102 (i.e., the flexible circuit board 103 is suspended relative to the housing assembly 101), and fixing the second locking part 1042 of the locking assembly 104 and the housing assembly 101; transferring the module within the factory for other series of processes; releasing the connection between the second locking part 1042 and the housing assembly 101; binding the flexible circuit board 103 and the display panel 102 together, while the second locking part 1042 rotates relative to the first locking part 1041 and latches onto the driver chip 1024 (which can be referred to as the locking structure and the driver chip 1024 being bound together), so that the second locking part 1042 protects the driver chip 1024.

[0135] It should be noted that, referring to Figure 1, when the first locking part 1041 and the second panel part 1023 are connected, the first connection point L1 of the first locking part 1041 and the second panel part 1023 is closer to the first panel part 1021 than the second connection point L2 of the flexible circuit board 103 and the second panel part 1023. Furthermore, the third connection point L3 of the driver chip 1024 and the second panel part 1023 is located between the first connection point L1 and the second connection point L2. In this case, when the second locking part 1042 and the housing assembly 101 are fixedly connected, the annular protrusion structure 10422 can be made further away from the housing assembly 101 relative to the second main body part 10421. Therefore, after the second locking part 1042 rotates relative to the first locking part 1041, the driver chip 1024 can be enclosed within the receiving groove 1042a.

[0136] When the first locking part 1041 and the flexible circuit board 103 are connected, the fourth connection point between the first locking part 1041 and the flexible circuit board 103 is farther away from the first panel portion 1021 relative to the second connection point L2 of the flexible circuit board 103 and the second panel portion 1023. Furthermore, the third connection point L3 between the driver chip 1024 and the second panel portion 1023 is located on the side of the second connection point L2 that is farther away from the fourth connection point. In this case, when the second locking part 1042 and the housing assembly 101 are fixedly connected, the annular protrusion structure 10422 can be made closer to the housing assembly 101 relative to the second main body portion 10421. Therefore, after the second locking part 1042 rotates relative to the first locking part 1041, the driver chip 1024 can be enclosed within the receiving groove 1042a.

[0137] In summary, this application provides a locking component applied in a display module. The display module includes a housing assembly, a display panel, and a flexible circuit board. After the flexible circuit board and the second panel portion of the display panel are fixedly connected, and both the flexible circuit board and the second panel portion are located outside the receiving cavity, the locking component can be fixedly connected to the housing assembly of the display module. The presence of the locking component can relatively fix the flexible circuit board and the housing assembly, reduce the shaking amplitude of the flexible circuit board, and reduce the force exerted by the shaking of the flexible circuit board on the bent portion of the display panel, preventing cracks from forming in the bent portion and improving the yield of the display module.

[0138] Figure 3 is a partial schematic diagram of a display module provided in an embodiment of this application. Referring to Figure 3, the display module 100 includes: a housing assembly 101, a display panel 102, a flexible circuit board 103, and a first locking part 1041 and a second locking part 1042 of a locking assembly 104. The locking assembly 104 may be the locking assembly 104 provided in the above embodiment.

[0139] The housing assembly 101 includes a first housing portion 1011 and a second housing portion 1012. The second housing portion 1012 has an annular structure and is connected to the edge of the first housing portion 1011. The first housing portion 1011 and the second housing portion 1012 constitute a receiving cavity 101a.

[0140] The display panel 102 includes a first panel portion 1021, a bent portion 1022, and a second panel portion 1023. The first panel portion 1021 and the bent portion 1022 are located within a receiving cavity 101a, with the bent portion 1022 positioned relative to the first panel portion 1021 near the edge of the receiving cavity 101a. The second panel portion 1023 is connected to the first panel portion 1021 via the bent portion 1022. A flexible circuit board 103 is connected to the second panel portion 1023.

[0141] The locking assembly 104 has a first locking portion 1041 and a second panel portion 1023 or a flexible circuit board 103 connected. In this embodiment, the first locking portion 1041 and the second panel portion 1023 are connected as an example. The second locking portion 1042 is rotatable relative to the first locking portion 1041, and the second locking portion 1042 is located on the side of the second panel portion 1023 away from the first panel portion 1021.

[0142] During the fabrication of the display module 100, referring to FIG. 2, after the display panel 102 and the housing assembly 101 are assembled, the first panel portion 1021 of the display panel 102 is located inside the receiving cavity 101a of the housing assembly 101. The bent portion 1022 is closer to the edge of the receiving cavity 101a than the first panel portion 1021. The second panel portion 1023 extends out of the receiving cavity 101a from the edge of the receiving cavity 101a, and the second panel portion 1023 can be located outside the receiving cavity 101a. Then, the flexible circuit board 103 and the second panel portion 1023 can be fixedly connected. In this case, the flexible circuit board 103 is also located outside the receiving cavity 101a, suspended on one side of the receiving cavity 101a of the housing assembly 101 relative to the housing assembly 101. After further processing (which may require handling the prepared module), the second panel portion 1023 can be bent via the bending portion 1022 to the side of the first panel portion 1021 away from the housing assembly 101, so that the flexible circuit board 103 is located on the side of the second panel portion 1023 away from the housing assembly 101. In this case, at least a portion of the flexible circuit board 103 is also located within the receiving cavity 101a, achieving a bonding connection between the flexible circuit board 103 and the second panel portion 1023 of the display panel 102.

[0143] Furthermore, during the process of the second panel portion 1023 gradually bending towards the side of the first panel portion 1021 away from the housing assembly 101 via the bending portion 1022 (i.e., during the bonding connection of the flexible circuit board 103 and the display panel 102), the second locking portion 1042 can rotate relative to the first locking portion 1041. Referring to FIG3, when the second panel portion 1023 is bent and disposed on the side of the first panel portion 1021 away from the housing assembly 101 via the bending portion 1022, and is located within the receiving cavity 101a (i.e., after the bonding connection of the flexible circuit board 103 and the display panel 102 is completed), the second locking portion 1042 can be located on the side of the second panel portion 1023 away from the first panel portion 1021. That is, due to the relative rotation of the second locking portion 1042 and the first locking portion 1041, the second locking portion 1042 can be engaged with the side of the second panel portion 1023 away from the first panel portion 1021.

[0144] After the flexible circuit board 103 and the display panel 102 are fixedly connected, and before they are bonded together (i.e., when the second panel portion 1023 is outside the receiving cavity 101a), the presence of the locking component 104 allows the second locking portion 1042 to remain fixedly connected to the housing assembly 101. Thus, even if the flexible circuit board 103 shakes, the locking component 104 indirectly fixes the flexible circuit board 103 to the housing assembly 101, providing some support for the flexible circuit board 103. This reduces the shaking amplitude of the flexible circuit board 103 and the force exerted by the shaking on the bent portion 1022 of the display panel 102, thereby reducing the impact of the shaking on the bent portion 1022, preventing cracks in the bent portion 1022, and improving the yield of the display module 100.

[0145] Furthermore, in order to achieve the bonding connection between the flexible circuit board 103 and the display panel 102, the fixed connection between the second locking part 1042 and the housing assembly 101 must be released before the bonding connection is established. That is, the second locking part 1042 and the housing assembly 101 are in a free state.

[0146] In this embodiment, after the flexible circuit board 103 and the display panel 102 are bonded together, the second locking part 1042 is fastened to the side of the second panel portion 1023 away from the first panel portion 1021, which can protect the devices at relevant positions on the second panel portion 1023. That is, the design of the locking component 104 in the display module can not only support the flexible circuit board 103 during the manufacturing process of the display module 100, but also protect the devices on the display panel 102.

[0147] Referring to Figure 4, the flexible circuit board 103 may include a connector 1031, a resistor or capacitor component 1032, and a plug 1033. The flexible circuit board 103 may also include other components, which are not limited in this embodiment.

[0148] In summary, this application provides a display module comprising a housing assembly, a display panel, and a flexible circuit board. After the flexible circuit board and the second panel portion of the display panel are fixedly connected, and both the flexible circuit board and the second panel portion are located outside the receiving cavity, a locking assembly can be fixedly connected to the housing assembly of the display module. The presence of the locking assembly allows the flexible circuit board and the housing assembly to be relatively fixed, reducing the wobbling amplitude of the flexible circuit board and the force exerted by the wobbling of the flexible circuit board on the bent portion of the display panel, preventing cracks from forming in the bent portion, and improving the yield of the display module.

[0149] Referring to Figures 1 to 11, the display panel 102 further includes a driver chip 1024. The driver chip 1024 is fixedly connected to the second panel portion 1023. The second locking part 1042 includes a second main body portion 10421 and an annular protrusion structure 10422 located on one side of the second main body portion 10421. The second main body portion 10421 and the annular protrusion structure 10422 form a receiving groove 1042a. The driver chip 1024 is located within the receiving groove 1042a, and the annular protrusion structure 10422 is disposed around the driver chip 1024. The second main body portion 10421 is located on the side of the driver chip 1024 away from the second panel portion 1023. For example, the annular protrusion structure 10422 is disposed around the driver chip 1024, and the second main body portion 10421 is located on the side of the driver chip 1024 away from the second panel portion 1023. In this case, it can be ensured that the driver chip 1024 is enclosed in the receiving groove 1042a of the second panel portion 1023, thus preventing other devices from affecting the driver chip 1024.

[0150] Optionally, if the locking assembly 104 includes a third locking part 1043, the display module 100 may also include a third locking part 1043. The third locking part 1043 may be fixedly connected to the surface of the second locking part 1042 away from the first locking part 1041.

[0151] Before the flexible circuit board 103 and the display panel 102 are bonded together, the third locking part 1043 is also used to fix it to the housing assembly 101. That is, the second locking part 1042 can be fixedly connected to the housing assembly 101 through the third locking part 1043, thereby providing support for the flexible circuit board 103.

[0152] Referring to Figures 15 and 16, the display module 100 further includes a protective film 105. The protective film 105 can be located on the side of the second locking portion 1042 away from the first locking portion 1041. Alternatively, the protective film 105 can be located between the second panel portion 1023 and the first locking portion 1041. This application embodiment does not limit the position of the protective film 105. The protective film can be a protective film (IC on panel tape, COP tape) used to protect the driver chip after it is connected to the display panel; that is, the main function of the protective film 105 is to protect the driver chip.

[0153] Optionally, the orthographic projection of the protective film 105 on the housing assembly 101 covers the orthographic projection of the second locking part 1042 on the housing assembly 101. Furthermore, the orthographic projection of the protective film 105 on the housing assembly 101 overlaps with the orthographic projection of the target portion of the flexible circuit board 103 on the housing assembly 101.

[0154] Referring to Figure 15, before the protective film 105 and the locking assembly 104 are assembled, the protective film 105 can be a flat film. Referring to Figure 16, after the protective film 105 is assembled, if the protective film 105 is located on the side of the second locking portion 1042 away from the first locking portion 1041, the shape of the surface formed by the protective film 105 can match the shape of the second locking portion 1042 and the target portion. If the protective film 105 is located between the second panel portion 1023 and the second locking portion 1042, the shape of the surface formed by the protective film 105 can match the shape of the target portion.

[0155] In summary, this application provides a display module comprising a housing assembly, a display panel, and a flexible circuit board. After the flexible circuit board and the second panel portion of the display panel are fixedly connected, and both the flexible circuit board and the second panel portion are located outside the receiving cavity, a locking assembly can be fixedly connected to the housing assembly of the display module. The presence of the locking assembly allows the flexible circuit board and the housing assembly to be relatively fixed, reducing the wobbling amplitude of the flexible circuit board and the force exerted by the wobbling of the flexible circuit board on the bent portion of the display panel, preventing cracks from forming in the bent portion, and improving the yield of the display module.

[0156] This application also provides a method for manufacturing a display module, the method comprising:

The first housing portion 1011 and the second housing portion 1012 constitute a receiving cavity 101a.

[0159] Step S102: Obtain the display panel and fix the display panel and housing assembly together.

[0160] The first panel portion 1021 of the display panel 102 is located inside the receiving cavity 101a, the bent portion 1022 of the display panel 102 is bent at the edge of the receiving cavity 101a, and the second panel portion 1023 of the display panel 102 is located outside the receiving cavity 101a.

Further, the locking component 104 may include a third locking portion 1043. Alternatively, the locking component 104 may include a support portion 1044, which includes a first support structure 10441 and a second support structure 10442.

[0163] Alternatively, the first locking portion 1041 of the acquired locking assembly 104 may be made of a sticky and flexible Mylar sheet. Or, the first locking portion 1041 and the second locking portion 1042 in the acquired locking assembly 104 may be rotated via a rotating shaft 10425.

[0164] Step S104: Securely connect the second locking part of the locking assembly and the housing assembly.

[0165] Optionally, the connection method between the second locking portion 1042 of the locking assembly 104 and the housing assembly 101 can be referred to Figures 4 to 7 above.

[0166] Step S105: Obtain the flexible circuit board and fix the flexible circuit board and the second panel part together.

[0167] In this embodiment, after the flexible circuit board 103 and the second panel portion 1023 are fixedly connected, the flexible circuit board 103 is also located outside the receiving cavity 101a. In this case, the flexible circuit board 103 is suspended relative to the housing assembly 101, and the locking assembly 104 can provide support for the flexible circuit board 103.

[0168] Step S106: Release the connection between the second locking part and the housing assembly, and bind the flexible circuit board and the display panel together.

[0169] In this embodiment, before the flexible circuit board 103 and the display panel 102 are bonded together, the connection between the second locking part 1042 and the housing assembly 101 can be released first, allowing the second panel portion 1023 to gradually bend towards the side of the first panel portion 1021 away from the housing assembly 101 via the bending part 1022. During this stage, the second locking part 1042 can rotate towards the first locking part 1041. After the flexible circuit board 103 and the display panel 102 are bonded together, the second panel portion 1023 can be located within the receiving cavity 101a, and the flexible circuit board 103 is located on the side of the first panel portion 1021 away from the housing assembly 101. Furthermore, a portion of the flexible circuit board 103 is located within the receiving cavity 101a. During this stage, the second locking part 1042 can be engaged on the side of the second panel portion 1023 away from the first panel portion 1021.

[0170] In this embodiment of the application, after step S106, step S107 may be included, in which a protective film 105 is used to cover the target portion of the second locking part 1042 and the flexible circuit board 103, so that the protective film 105 can protect the second locking part 1042 and the target portion of the flexible circuit board 103.

In this case, the flexible circuit board 103 is suspended relative to the housing assembly 101, and the locking assembly 104 is fixedly connected to the housing assembly 101, so that the locking assembly 104 can support the flexible circuit board 103.

[0181] Step S106: Release the connection between the second locking part and the housing assembly, and bind the flexible circuit board and the display panel together.

[0182] In this embodiment, before the flexible circuit board 103 and the display panel 102 are bonded together, the connection between the second locking part 1042 and the housing assembly 101 can be released first, allowing the second panel portion 1023 to gradually bend towards the side of the first panel portion 1021 away from the housing assembly 101 via the bending part 1022.

[0184] This application also provides another method for manufacturing a display module, the method comprising:

[0185] Step S301: Obtain the shell assembly.

[0189] Step S303: Obtain the protective film and the locking assembly, and connect the first locking part of the locking assembly and the protective film.

[0190] In this embodiment of the application, referring to FIG20, the first locking portion 1041 of the locking component 104 can be fixedly connected to one side of the protective film 105. The protective film 105 is a flat film when it does not cover the flexible circuit board 103.

[0191] In this embodiment, the acquired locking component 104 may include at least a first locking portion 1041 and a second locking portion 1042. Further, the locking component 104 may also include a third locking portion 1043.

[0193] Step S304: Connect the first locking part and the protective film of the locking assembly as a whole to the second panel part.

[0194] In this embodiment, the protective film 105 is closer to the second panel portion 1023 than the first locking portion 1041. That is, the protective film 105 is located between the first locking portion 1041 and the second panel portion 1023.

[0201] This application also provides another method for manufacturing a display module, the method comprising:

[0202] Step S401: Obtain the display panel and the flexible circuit board, and fix the display panel and the flexible circuit board together.

[0203] In this embodiment, the display panel 102 is a flat panel before being fixedly connected to the housing assembly 101. Therefore, after the display panel 102 and the flexible circuit board 103 are fixedly connected, the display panel 102 and the flexible circuit board 103 can be substantially on the same plane. For example, the display panel 102 and the flexible circuit board 103 can be placed on a support platform of the equipment during the manufacturing process.

[0204] Step S402: Obtain the housing assembly and fix the display panel and housing assembly together.

[0205] The housing assembly 101 includes a first housing portion 1011 and a second housing portion 1012. The second housing portion 1012 has an annular structure and is connected to the edge of the first housing portion 1011. The first housing portion 1011 and the second housing portion 1012 constitute a receiving cavity 101a.

[0206] After the display panel 102 is fixedly connected to the housing assembly 101, the first panel portion 1021 of the display panel 102 is located inside the receiving cavity 101a, the bent portion 1022 of the display panel 102 is bent at the edge of the receiving cavity 101a, and the second panel portion 1023 of the display panel 102 is located outside the receiving cavity 101a.

[0212] In this embodiment, the protective film 105 is closer to the second panel portion 1023 than the first locking portion 1041. That is, the protective film 105 is located between the first locking portion 1041 and the second panel portion 1023.

[0213] Step S405: Securely connect the second locking part of the locking assembly and the housing assembly.

[0214] Optionally, the connection method between the second locking portion 1042 of the locking assembly 104 and the housing assembly 101 can be referred to Figures 4 to 7 above. Alternatively, if the locking assembly 104 includes a third locking portion 1043, the third locking portion 1043 can be bonded to the surface of the housing assembly 101 away from the receiving cavity 101a, thereby fixing the second locking portion 1042 to the housing assembly 101 through the third locking portion 1043.

[0215] Step S406: Release the connection between the second locking part and the housing assembly, and bind the flexible circuit board and the display panel together.

[0216] In this embodiment, before the flexible circuit board 103 and the display panel 102 are bonded together, the connection between the second locking part 1042 and the housing assembly 101 can be released first, allowing the second panel portion 1023 to gradually bend towards the side of the first panel portion 1021 away from the housing assembly 101 via the bending part 1022. During this stage, the second locking part 1042 can rotate towards the first locking part 1041.

As mentioned above, all four fabrication methods can achieve the fabrication of the display module. Of course, besides the four fabrication methods described above, other methods can also be used to fabricate the display module, which will not be detailed in this embodiment.

[0218] Since the manufacturing method of the display module can have essentially the same technical effect as the display module described in the previous embodiments, for the sake of brevity, the technical effect of the manufacturing method of the display module will not be described again here.

[0219] This application also provides a display device, which may include a power supply component and a display module as provided in the above embodiments. The power supply component and the display module are connected, and the power supply component supplies power to the display module.

[0220] Optionally, the shape of the display module can depend on the shape of the housing assembly 101, that is, the shape of the display module 100 matches the shape of the housing assembly 101. For example, the housing assembly 101 in the above embodiment can be circular, and thus the display module 100 can also be circular. Of course, if the housing assembly 101 is square, the display module 100 can also be square.

[0221] Optionally, if the display panel can be an organic light-emitting diode (OLED) display panel, then the display device can be an OLED display device. For example, if the display panel can be an active-matrix organic light-emitting diode (AMOLED) display panel, then the display device can be an AMOLED display device.

[0222] Optionally, the display device can be a wearable display device. A wearable display device can be a smartwatch. Alternatively, the display device can be any suitable display device, including but not limited to mobile phones, tablets, televisions, monitors, laptops, digital photo frames, navigators, and e-readers—any product or component with a display function.

[0223] Since the display device can have essentially the same technical effects as the display module described in the previous embodiments, for the sake of brevity, the technical effects of the display module will not be described again here.
