Description

Display modules and electronic devices

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on December 15, 2023, with application number 202323442232.6 and application name “Display Module and Electronic Device,” all contents of which are incorporated by reference into this application. Technical Field

[0002] The embodiments of the present application relate to the display field, and in particular to a display module and an electronic device. Background Art

[0003] As the functions of display terminals, such as mobile phones, continue to diversify, multiple devices for implementing different functions are integrated into the mobile phones, such as cameras, fingerprint sensors and other functional devices.

[0004] Unlike candy-bar phones, foldable modules are made of flexible materials with relatively low hardness. When a user's fingernail or a sharp object presses against the openings of the display module housing functional components, the layers of the module can bend and deform in this area, resulting in failures such as black spots and bright spots. Therefore, improving the compressibility of the display module openings is a pressing issue.

[0005] Utility Model Content

[0006] The embodiments of the present application provide a display module and an electronic device, which solve the problem that the existing display modules are prone to failure due to extrusion.

[0007] To achieve the above objectives, the present invention adopts the following technical solutions:

[0008] According to a first aspect of an embodiment of the present application, a display module is provided, which is used in an electronic device, the electronic device comprising: a functional device, the display module comprising: a stacked protective layer, a display panel, and a support member, the display panel having a through hole, the support member having a first alignment hole, the through hole and the first alignment hole being connected, the through hole, the first alignment hole, and the cover plate forming a first cavity, the functional device being disposed in the first cavity; the aperture of the first alignment hole being smaller than or equal to the aperture of the through hole. Thus, when the aperture of the first alignment hole is smaller than the aperture of the through hole, the support member expands outward relative to the display panel toward the location of the functional device to form a cantilever, and when the aperture of the first alignment hole is equal to the aperture of the through hole, the alignment hole of the support member is flush with the edge of the through hole of the display panel. In this way, when a user presses the opening position, the support member can better support the display panel disposed thereon, thereby reducing the curvature of the display panel, reducing damage to the display panel, and improving the anti-extrusion capability of the opening area of ​​the display module.

[0009] In an optional implementation, the support member includes: a flexible support member and a rigid support plate, the flexible support member is connected to the display panel, and the rigid support plate is arranged on the side of the flexible support member away from the display panel. As a result, the rigid support plate has a higher modulus and can play a supporting role, while restraining the deformation of the flexible support member to prevent it from producing irreversible deformation, while the flexible support member has better buffering performance and can absorb vertical impact energy through appropriate deformation, and its deformation is controlled within the controllable range of the rigid support plate. The rigid support plate and the flexible support member have a significant synergistic attenuation effect on bending energy, which improves the bending performance of the support member and reduces the risk of film peeling caused by buckling instability of the support member in scenarios such as rapid bending. The terminal device equipped with the support member can have good bending performance. When bending occurs, the lower limit of the buckling deformation is increased, while taking into account the buffering performance of the film layer.

[0010] In one optional implementation, the electronic device further comprises a bracket, the bracket being disposed on a side of the support member away from the display panel, the bracket being connected to the support member, the bracket being provided with a second alignment hole, the second alignment hole being connected to the first alignment hole, the aperture of the second alignment hole being smaller than or equal to the aperture of the through hole of the display panel. Thus, disposing a bracket below the support member that extends outward from the display panel or is flush with the display panel can better support the display panel. When a user presses the opening area on a surface, the support member and the bracket jointly support the display panel, further reducing the curvature and improving the display module's ability to resist extrusion.

[0011] In one optional implementation, the support member further includes a metal layer. The surface of the bracket proximate the display panel includes a first region and a second region, the first region being disposed around the functional device, the second region being disposed around the first region, the metal layer being disposed between the first region and the display panel, the metal layer being provided with a third alignment hole, the third alignment hole being connected to the second alignment hole, the metal layer being connected to the display panel via a first adhesive backing, and the second region being connected to the display panel via a second adhesive backing. Thus, by providing the metal layer between the support member and the midframe, the display panel can be better supported, thereby improving the display panel's resistance to extrusion.

[0012] In an optional implementation, the bracket and the metal layer are integrally formed, thereby integrating the bracket with supporting performance and the metal layer, further improving the anti-bending performance of the display module.

[0013] In one optional implementation, the diameter of the third alignment hole is smaller than or equal to the diameter of the through hole. Thus, providing a metal layer below the support member that extends beyond or is flush with the display panel can better support the display panel. When a user presses the opening area on a surface, the support member, metal layer, and bracket below the display panel jointly support it, reducing curvature and improving the display module's ability to resist extrusion.

[0014] In an optional implementation, the diameter of the through hole is equal to the diameter of the first alignment hole, and the display panel and the support member are integrally formed by laser cutting. As a result, the apertures of the two structural members have the same diameter and can be integrally formed by laser cutting, reducing the process difficulty.

[0015] In an optional implementation, the display panel is foldable. As such, the display panel is a flexible display screen that is susceptible to deformation and damage when pressed by a user. This application provides a support member that is either outwardly flared or flush beneath the display panel to better protect the display panel and improve its anti-bending performance.

[0016] In an optional implementation, the protective layer includes: a stacked cover plate and a protective film, wherein the cover plate is disposed on the display panel and the protective film is disposed on the cover plate. Thus, the cover plate and the protective film can be used to protect the display panel.

[0017] In one optional implementation, the display module further includes a polarizer and a backing film. The polarizer is disposed between the display module and the protective layer, and the backing film is disposed between the display panel and the support member. Both the polarizer and the backing film are provided with through holes, and the apertures of the through holes in the polarizer and the backing film are equal to the aperture of the display panel. Thus, providing through holes in the polarizer and the backing film facilitates the installation of functional components.

[0018] A second aspect of the present application provides an electronic device comprising: a functional device and the display module described above, wherein the display module includes a first cavity, and the functional device is disposed within the first cavity. Thus, the electronic device employing the display module has improved compression resistance in the opening area.

[0019] In an optional implementation, the electronic device further includes a middle frame, on which the display module is disposed, so that the middle frame can be used to support the display module.

[0020] An embodiment of the present application discloses a display module and an electronic device, which includes: a functional device, the display module includes: a stacked protective layer, a display panel and a support member, the display panel is provided with a through hole, the support member is provided with a first alignment hole, the through hole and the first alignment hole are connected, the through hole, the first alignment hole and the cover plate are arranged to form a first cavity, the functional device is arranged in the first cavity, in some embodiments, the aperture of the first alignment hole is smaller than the aperture of the through hole, so that the support member expands outward toward the position of the functional device relative to the display panel to produce a cantilever, in other embodiments, the aperture of the first alignment hole is equal to the aperture of the through hole, the alignment hole of the support member is flush with the edge of the through hole of the display panel, so that the support member can better support the display panel arranged above it, reduce the curvature of the display panel, reduce damage to the display panel, and improve the anti-extrusion ability of the opening area of ​​the display module.

[0031] The embodiment of the present application provides an electronic device. The electronic device can be a product with a display interface such as a tablet computer, a mobile phone, an e-reader, a remote control, a personal computer (PC), a laptop computer, a personal digital assistant (PDA), a vehicle-mounted device, an Internet TV, a wearable device, a television, and a smart display wearable product such as a smart watch and a smart bracelet. The embodiment of the present application does not impose any special restrictions on the form of the above-mentioned electronic device. For the sake of convenience of explanation, the following embodiments are all exemplified by taking the electronic device as a mobile phone.

[0032] As shown in FIG1 , the electronic device 1 includes a display module 10 , a middle frame 11 , and a housing (or battery cover, rear housing) 12 . The middle frame 11 is located between the display module 10 and the housing 12 .

[0033] The display module 10 is used to display images.

[0034] The middle frame 11 is located between the display module 10 and the housing 12. The surface of the middle frame 11, facing away from the display module 10, is used to mount internal components such as the battery, printed circuit board (PCB), camera, and antenna. When the housing 12 and middle frame 11 are closed, these internal components are located between the housing 12 and the middle frame 11.

[0035] For example, as shown in FIG. 1 , the middle frame 11 includes a carrying plate 110 and a frame 112 surrounding the carrying plate 110 .

[0036] The surface of the carrier plate 110 facing the housing 12 can be equipped with a printed circuit board (PCB), a camera, a battery, and other electronic components. The camera is not shown in the figure. The housing 12 is connected to the middle frame 11 to form a cavity for accommodating the PCB, camera, battery, and other electronic components. This prevents external moisture and dust from intruding into the cavity and affecting the performance of the electronic components.

[0037] The display module 10 can be electrically connected to a PCB disposed on the carrier board 110 by passing a flexible printed circuit (FPC) through the carrier board 110 as shown in FIG1 . This allows the PCB to transmit display data to the display module 10 to control the display module 10 to display images.

[0038] The display module 10, the middle frame 11, and the housing 12 can be arranged in different layers in the thickness direction of the electronic device. These layers can be parallel to each other. The plane in which each layer is located can be called the XY plane, and the direction perpendicular to the XY plane can be called the Z direction. In other words, the display module 10, the middle frame 11, and the housing 12 can be arranged in layers in the Z direction.

[0039] In one implementation of the present application, an electronic device 1, as shown in FIG2 , includes a display module 10 and a functional device 20. The display module 10 has a display area 100 for displaying images, and a frame area 1001 located outside the display area 100. The functional device 20 is disposed within the display area 100 of the display module 10. The frame area 1001 is provided with a driving circuit, such as a source driving circuit and a gate driving circuit, for driving a display panel 102 to display images.

[0040] It should be noted that the functional device 20 may be an optical device, such as a flash, a camera, a proximity light sensor, an ambient light sensor, a fingerprint sensor, and the like.

[0041] The embodiment of the present application does not limit the structure of the display module 10 .

[0042] FIG3 is a cross-sectional view taken along line AA of the display module 10 in FIG2 . As shown in FIG3 , the display module 10 at least includes a cover plate 101 and a display panel 102 .

[0043] The display panel 102 has a display surface a1 for viewing a display image and a back surface a2 opposite to the display surface a1, the back surface a2 of the display panel 102 being close to the middle frame 11. The display surface a1 of the display panel is provided with, for example, a polarizer 1021, and the back surface a2 is provided with, for example, a back film 1022.

[0044] In one possible embodiment of the present application, the display panel 102 is a flexible display screen. For example, the display panel 102 may be an organic light-emitting diode (OLED) display panel. Because each light-emitting sub-pixel in an OLED display panel is provided with an electroluminescent layer, the OLED display panel can emit light upon receiving an operating voltage.

[0045] The cover plate 101 is located on the light-emitting side of the display panel 102 . The cover plate 101 may be, for example, a cover glass (CG), which may have a certain toughness.

[0046] The cover plate 101 includes a first surface and a second surface opposite to each other. The first surface of the cover plate 101 is close to the display surface a1 of the display panel 102 .

[0047] In some embodiments of the present application, a protective layer 1011 is provided on the surface of the cover plate 101 , and the protective layer 1011 is provided on a side of the cover plate 101 away from the display panel 102 .

[0048] In some embodiments, as shown in FIG. 3 , the display module 10 further includes a support member 103 . The support member 103 is disposed between the display panel 102 and the middle frame 11 . The support member 103 is used to support the display panel 102 .

[0049] The embodiment of the present application does not limit the connection method between the support member 103 and the middle frame 11. In some embodiments of the present application, the support member 103 can be connected to the middle frame 11 through the adhesive 104.

[0050] In some embodiments, as shown in Figure 3, through holes are provided on the display panel 102, the polarizer 1021, and the back film 1022, and alignment holes connected to the through holes are provided on the support member 103, the back glue 104 and the middle frame 11. No holes are provided on the cover plate 101 and the protective layer 1011. The through holes of the display panel 102, the polarizer 1021, and the back film 1022 and the alignment holes of the support member 103, the back glue 104 and the middle frame 11 and the cover plate 101 are arranged to form a cavity, and the functional device 20 is arranged in the cavity.

[0051] Continuing with Figure 3 , the through-holes in the display panel 102, polarizer 1021, and backing film 1022 have the same aperture. The alignment holes in the support member 103 have a larger aperture than the through-holes in the display panel 102, polarizer 1021, and backing film 1022. The alignment holes in the adhesive backing 104 and the middle frame 11 also have larger apertures than the through-holes in the display panel 102, polarizer 1021, and backing film 1022.

[0052] As shown in Figure 4, when a user's fingernail or a sharp object presses against the opening area from the front, the layers of the foldable display module's opening area bend and deform, producing dark spots and bright spots on the display panel. The failure force is 3.5 kgf, which corresponds to approximately 5000 ppm (parts per million) in the market. This means that failure occurs at relatively low pressure, resulting in a high Fault Feedback Ratio (FFR). Therefore, improving the extrusion resistance of the display module's opening area is an urgent issue.

[0053] In order to improve the anti-extrusion performance of the display module 10 in the opening area, an embodiment of the present application provides an improved display module.

[0054] Figure 5 is a schematic diagram of the structure of the first display module provided in an embodiment of the present application. Figure 6 is a schematic diagram of the structure of the second display module provided in an embodiment of the present application. As shown in Figures 5 and 6, the display module 10 includes a functional device 20 and the following stacked components arranged along the z-direction: a protective layer 1011, a cover plate 101, a polarizer 1021, a display panel 102, a backing film 1022, a support member 103, an adhesive backing 104, and a middle frame 11.

[0055] In some embodiments, the display panel 102 is an active matrix organic light emitting diode (AMOLED) display screen.

[0056] AMOLED displays are self-luminous displays that do not require a backlight module (BLM). Therefore, when the base substrate of an AMOLED display is made of a flexible resin material, such as polyethylene terephthalate (PET), the AMOLED display can be bendable.

[0057] The cover plate 101 and the protective layer 1011 can protect the display panel 102 and prevent the external environment from interfering with the display panel 102 .

[0058] As shown in FIG. 5 and FIG. 6 , no holes are provided on the cover plate 101 and the protective layer 1011 .

[0059] 5 and 6 , through holes are provided on the polarizer 1021, the display panel 102, and the back film 1022, and alignment holes are provided on the support member 103, the back glue 104, and the middle frame 11. The through holes of the polarizer 1021, the display panel 102, the back film 1022, the alignment holes of the support member 103, the back glue 104, and the middle frame 11, and the cover plate 101 are arranged to form a first cavity, and the functional device 20 is arranged in the first cavity.

[0060] 5 and 6 , in conjunction with FIG3 , the diameter of the alignment hole of the support member 103 is smaller than or equal to the diameter of the through hole of the display panel 102. The through hole of the display panel 102 serves as the first through hole, and the alignment hole of the support member 103 serves as the first alignment hole. The first through hole and the first alignment hole are connected, and the first through hole and the first alignment hole are used to accommodate the functional device 20.

[0061] In some embodiments, the axes of the through hole and the first alignment hole coincide, and the axes of the through hole and the first alignment hole also coincide with the axis of the functional device 20. This allows the functional device 20 to be positioned midway between the through hole and the first alignment hole, improving the optical performance of the functional device 20. Furthermore, the coaxial arrangement of the through hole and the first alignment hole makes the spacing between the inner wall of the support member 103 and the functional device 20, as well as the spacing between the inner wall of the display panel 102 and the functional device 20, more uniform, reducing interference with the functional device 20 from the support member 103 or the display panel 102.

[0062] As shown in Figure 5, the aperture of the first alignment hole is smaller than the aperture of the through hole, and the support member 103 expands outward relative to the display panel 102 to form a cantilever. In this way, when the user presses the opening position, the support member 103 can better support the display panel 102 set above it, reducing the curvature of the display panel 102, reducing damage to the display panel 102, and improving the display module's anti-extrusion ability.

[0063] As shown in Figure 6, the aperture of the first alignment hole is equal to the aperture of the through hole, and the projections of the edges of the support member 103 and the display panel 102 on the cover plate 101 coincide with each other. In this way, when the user presses the opening position, the support member 103 can well support the display panel 102 arranged above it, thereby reducing the curvature of the display panel 102, reducing damage to the display panel 102, and improving the anti-extrusion ability of the display module.

[0064] 5 , the support member 103 in FIG6 is smaller in size, and the support member 103 is flush with the display panel 102 . When processing the support member 103 and the display panel 102 , the support member 103 and the display panel 102 can be bonded together and then integrally cut using laser, which simplifies the process.

[0065] A polarizer 1021 is provided on the surface of the display panel 102 close to the cover plate 101, and a back film 1022 is provided on the surface of the display panel 102 away from the cover plate 101. Through holes are also provided on the polarizer 1021 and the back film 1022. The aperture of the through holes on the polarizer 1021 and the back film 1022 is the same as the aperture of the through holes of the display panel 102.

[0066] The support member 103 is disposed on a side of the display panel 102 away from the cover plate 101 .

[0067] The present application does not limit the structure of the support member 103. In some embodiments, the support member 103 includes a stacked flexible support member 1031 and a rigid support plate 1032. The flexible support member 1031 is connected to the display panel 102, and the rigid support plate 1032 is disposed on a side of the flexible support member 1031 away from the display panel 102.

[0068] The embodiment of the present application does not limit the materials of the flexible support member 1031 and the rigid support plate 1032. The material of the flexible support member 1031 includes: rubber, polymer (polyethylene terephthalate, polyimide (PI)) film and other materials with low modulus.

[0069] The material of the rigid support plate 1032 includes: metal, carbon fiber and other materials with high modulus.

[0070] Thus, support member 103 includes a flexible support member 1031 and a rigid support plate 1032. When rigid support plate 1032 and flexible support member 1031 are arranged together, rigid support plate 1032 has a higher modulus and can provide support while restraining the deformation of flexible support member 1031 and preventing it from undergoing irreversible deformation. Flexible support member 1031 has excellent cushioning performance and can absorb vertical impact energy through appropriate deformation, while its deformation is controlled within the controllable range of rigid support plate 1032. The synergistic attenuation effect of rigid support plate 1032 and flexible support member 1031 on bending energy is significant, improving the bending performance of support member 103 and reducing the risk of film peeling caused by buckling instability of support member 103 in scenarios such as rapid bending. This enables a terminal device equipped with support member 103 to have excellent bending performance. When bending occurs, the lower limit of buckling deformation is increased while taking into account the cushioning performance of the film layer.

[0071] As shown in FIG. 5 and FIG. 6 , the through holes on the display panel 102 , the polarizer 1021 , and the back film 1022 have the same aperture, which is larger than the aperture of the alignment hole of the support member 103 .

[0072] Therefore, in the present application, a support member 103 is provided under the display panel 102, which is larger than the display panel 102 or flush with the display panel 102. The support member 103 can better support the display panel 102. When the user presses the opening area on the surface, the display panel 102 is supported by the support member 103 under the bottom, and the curvature is reduced, thereby improving the anti-extrusion ability of the display module.

[0073] In some embodiments, the display module 10 further includes: a bracket, which is arranged on a side of the support member away from the display panel, the bracket is connected to the support member, and a second alignment hole is provided on the bracket, and the second alignment hole is connected to the first alignment hole.

[0074] For example, in the present application, the bracket may be a middle frame 11 as shown in FIG. 5 and FIG. 6 , and a second alignment hole is provided on the middle frame 11 , which may be used to accommodate the functional device 20 .

[0075] The embodiments of the present application do not limit the diameter of the second alignment hole. In some embodiments, the diameter of the second alignment hole is less than or equal to the diameter of the display panel 102. Thus, in this application, a bracket is provided below the support member 103 that extends outward from or is flush with the display panel 102, thereby better supporting the display panel 102. When a user presses the opening area on a surface, the support member 103 and the bracket provide support from below the display panel 102, further reducing the curvature and improving the display module's resistance to compression.

[0076] The embodiment of the present application does not limit the connection method between the support member 103 and the bracket. In some embodiments, the support member 103 is connected to the bracket via adhesive 104.

[0077] In some embodiments, the adhesive backing 104 is also provided with an alignment hole. The present embodiment does not restrict the diameter of the alignment hole on the adhesive backing 104, and the diameter of the alignment hole on the adhesive backing 104 can be maximized. For example, the alignment hole on the adhesive backing 104 can be larger than or equal to the larger diameter of the second and third alignment holes. This allows the adhesive backing 104 to be retracted relative to the support member 103 and the bracket, or aligned flush with the larger alignment hole, preventing the adhesive backing 104 from being exposed to air or dust.

[0078] To further improve the anti-extrusion performance of the display panel, in some embodiments, as shown in Figures 7 and 9, the display module 10 also includes: a metal layer 105, and the surface of the middle frame 11 close to the display panel 102 includes: a first area and a second area, the first area is arranged around the functional device, and the second area is arranged around the first area, the metal layer 105 is arranged between the first area and the display panel, and a third alignment hole is provided on the metal layer 105, and the third alignment hole is connected to the second alignment hole.

[0079] The third alignment hole can be used together with other alignment holes to set the functional device 20 .

[0080] In this embodiment, the metal layer 105 is provided between the support member 103 and the middle frame 11 , so as to better support the display panel 102 and improve the anti-extrusion capability of the display panel.

[0081] In some embodiments, as shown in FIG. 7 and FIG. 9 , the metal layer 105 is connected to the display panel 102 via the second adhesive 1042 , and the second region is connected to the display panel 102 via the first adhesive 1041 .

[0082] The embodiment of the present application does not limit the connection method between the metal layer 105 and the middle frame 11. In some embodiments, as shown in FIG. 9 , the middle frame 11 and the metal layer 105 are integrally formed.

[0083] The embodiment of the present application does not limit the diameter of the third alignment hole. In some embodiments, the diameter of the third alignment hole can be smaller than or equal to the diameter of the display panel 102.

[0084] Therefore, in this application, a metal layer 105 is set below the support member 103, which is larger than the display panel 102 or flush with the display panel 102. The metal layer 105 can better support the display panel 102. When the user presses the opening area on the surface, the support member 103, the metal layer 105 and the bracket under the display panel 102 jointly support it, and the curvature is reduced, thereby improving the anti-extrusion ability of the display module.

[0085] The display module involved in this application is described below with reference to Figures 5, 6, 7, 8, 9 and 10.

[0086] As shown in FIG5 , the display module 10 includes a functional device 20 and a protective layer 1011 , a cover plate 101 , a polarizer 1021 , a display panel 102 , a back film 1022 , a support 103 , a backing adhesive 104 and a middle frame 11 stacked along the z direction.

[0087] There are no holes on the cover plate 101 and the protective layer 1011 .

[0088] Through holes are provided on the polarizer 1021, the display panel 102, and the back film 1022, and alignment holes are provided on the support member 103, the back glue 104, and the middle frame 11. The polarizer 1021, the display panel 102, the through holes on the back film 1022, the support member 103, the back glue 104, the alignment holes of the middle frame 11, and the cover plate 101 are arranged to form a first cavity, and the functional device 20 is arranged in the first cavity.

[0089] 5 , the alignment hole of the support member 103 has a diameter smaller than or equal to the diameter of the through hole of the display panel 102. The through hole of the display panel 102 serves as a through hole, and the alignment hole of the support member 103 serves as a first alignment hole. The through hole and the first alignment hole are connected, and the through hole and the first alignment hole are used to accommodate the functional device 20.

[0090] In some examples of this embodiment, the axes of the through hole and the first alignment hole can be aligned, and the axes of the through hole and the first alignment hole can also coincide with the axis of the functional device 20. This allows the functional device 20 to be positioned midway between the through hole and the first alignment hole, improving the optical performance of the functional device 20. Furthermore, the coaxial arrangement of the through hole and the first alignment hole makes the spacing between the inner wall of the support member 103 and the functional device 20, as well as the spacing between the inner wall of the display panel 102 and the functional device 20, more uniform, reducing interference with the functional device 20 from the support member 103 or the display panel 102.

[0091] Referring to Figure 5, the aperture of the first alignment hole is smaller than the aperture of the through hole, and the support member 103 expands outward toward the position of the functional device relative to the display panel 102 to form a cantilever. In this way, when the user presses the opening position, the support member 103 can better support the display panel 102 arranged above it, reducing the curvature of the display panel 102, reducing damage to the display panel 102, and improving the anti-extrusion ability of the display module.

[0092] A polarizer 1021 is provided on the surface of the display panel 102 close to the cover plate 101, and a back film 1022 is provided on the surface of the display panel 102 away from the cover plate 101. Through holes are also provided on the polarizer 1021 and the back film 1022. The aperture of the through holes on the polarizer 1021 and the back film 1022 is the same as the aperture of the through holes of the display panel 102.

[0093] The support member 103 is disposed on a side of the display panel 102 away from the cover plate 101 . In some examples of this embodiment, the through holes on the display panel 102 , the polarizer 1021 , and the backing film 1022 have the same aperture, which is larger than the alignment hole of the support member 103 .

[0094] Therefore, in the present application, a support member 103 is provided under the display panel 102, which is larger than the display panel 102 or flush with the display panel 102. The support member 103 can better support the display panel 102. When the user presses the opening area on the surface, the display panel 102 is supported by the support member 103 under the bottom, and the curvature is reduced, thereby improving the anti-extrusion ability of the display module.

[0095] This embodiment does not limit the structure of the support member 103. In some embodiments, the support member 103 includes a stacked flexible support member 1031 and a rigid support plate 1032. The flexible support member 1031 is connected to the display panel 102, and the rigid support plate 1032 is disposed on a side of the flexible support member 1031 away from the display panel 102.

[0096] The flexible support members 1031 and the rigid support plates 1032 in the support member 103 are arranged alternately. The rigid support plates 1032 have a higher modulus and can provide support while restraining the deformation of the flexible support member 1031 and preventing it from undergoing irreversible deformation. The flexible support member 1031 has excellent cushioning performance and can absorb vertical impact energy through appropriate deformation, and its deformation is controlled within the controllable range of the rigid support plates 1032. The rigid support plates 1032 and the flexible support members 1031 have a significant synergistic attenuation effect on bending energy, which improves the bending performance of the support member 103 and reduces the risk of film peeling caused by buckling instability of the support member 103 in scenarios such as rapid bending. This enables the terminal device equipped with the support member 103 to have good bending performance. When bending occurs, the lower limit of the buckling deformation is increased, while taking into account the cushioning performance of the film layer.

[0097] In some embodiments, the display module 10 further includes a middle frame 11, which is disposed on a side of the support member 103 away from the display panel 102. The middle frame 11 is connected to the support member 103. The middle frame 11 is provided with, for example, a second alignment hole, which communicates with the first alignment hole. The through hole, the first alignment hole, and the second alignment hole can all be used to accommodate the functional device 20.

[0098] The embodiments of the present application do not limit the diameter of the second alignment hole. In some embodiments, the diameter of the second alignment hole is less than or equal to the diameter of the display panel 102. Thus, in this application, a bracket is provided below the support member 103 that extends outward from or is flush with the display panel 102, thereby better supporting the display panel 102. When a user presses the opening area on a surface, the support member 103 and the bracket provide support from below the display panel 102, further reducing the curvature and improving the display module's resistance to compression.

[0099] The embodiment of the present application does not limit the connection method between the support member 103 and the bracket. In some embodiments, the support member 103 is connected to the bracket via adhesive 104.

[0100] In some embodiments, the adhesive backing 104 is also provided with an alignment hole. The present embodiment does not impose any restrictions on the diameter of the alignment hole in the adhesive backing 104, and the diameter of the alignment hole in the adhesive backing 104 can be maximized. For example, the alignment hole in the adhesive backing 104 can be larger than or equal to the larger diameter of the second and third alignment holes. This allows the adhesive backing 104 to be retracted relative to the support member 103 and the bracket, or aligned flush with the larger alignment hole, preventing the adhesive backing 104 from coming into contact with air or dust.

[0101] Referring to Figure 6 and Figure 5 , the aperture of the first alignment hole is equal to the aperture of the through hole, and the projections of the edges of the support member 103 and the display panel 102 on the cover plate 101 coincide with each other. In this way, when the user presses the opening position, the support member 103 can well support the display panel 102 arranged above it, thereby reducing the curvature of the display panel 102, reducing damage to the display panel 102, and improving the anti-extrusion ability of the display module.

[0102] Therefore, compared with the first embodiment, the size of the support member 103 is smaller.

[0103] When the support member 103 is made of a material with relatively low hardness, such as carbon fiber, it can be formed by laser cutting.

[0104] In this way, the support member 103 and the display panel 102 are flush. When processing the support member 103 and the display panel 102, the polarizer 1021, the display panel 102, the back film 1022 and the support member 103 can be attached together, and then laser cutting is used to form the integrated structure, which simplifies the process.

[0105] This embodiment does not limit the structure of the support member 103. In some embodiments, the support member 103 may be a laminated structure, including a flexible support member 1031 and a rigid support plate 1032 that are stacked.

[0106] In other embodiments, the support member 103 is a single-layer structure with fewer layers, which reduces the difficulty of laser cutting.

[0107] Referring to Figure 7 and in combination with Figure 5, the display module 10 also includes: a metal layer 105, and the surface of the middle frame 11 close to the display panel 102 includes: a first area and a second area, the first area is arranged around the functional device, and the second area is arranged around the first area, the metal layer 105 is arranged between the first area and the display panel, and a third alignment hole is provided on the metal layer 105, and the third alignment hole is connected to the second alignment hole.

[0108] The third alignment hole can be used together with other alignment holes to accommodate the functional device 20 .

[0109] In this embodiment, the metal layer 105 is provided between the support member 103 and the middle frame 11 , so as to better support the display panel 102 and improve the anti-extrusion capability of the display panel.

[0110] In some embodiments, as shown in FIG. 7 , the metal layer 105 is connected to the display panel 102 via the second adhesive 1042 , and the second region is connected to the display panel 102 via the first adhesive 1041 .

[0111] The embodiment of the present application does not limit the diameter of the third alignment hole. In some embodiments, the diameter of the third alignment hole can be smaller than or equal to the diameter of the display panel 102.

[0112] Therefore, in this application, a metal layer 105 is set below the support member 103, which is larger than the display panel 102 or flush with the display panel 102. The metal layer 105 can better support the display panel 102. When the user presses the opening area on the surface, the support member 103, the metal layer 105 and the bracket under the display panel 102 jointly support it, and the curvature is reduced, thereby improving the anti-extrusion ability of the display module.

[0113] As shown in FIG8 , an extrusion test is performed on the display module shown in FIG7 . During extrusion, the support member 103 below the display panel 102 can well support the display panel 102 , preventing the display panel 102 from bending in a cantilever beam state. The failure force value of the display panel 102 producing black spots and bright spots is increased from 3.5 kgf to 6.5 kg, thereby improving the anti-extrusion ability of the opening area of ​​the display module.

[0114] 9 , in combination with FIG7 , the middle frame 11 and the metal layer 105 are integrally formed. Thus, multiple components with supporting properties are integrally formed, further improving the anti-bending performance of the display module.

[0115] In some embodiments, the support member 103 is made of a material with relatively low hardness, such as carbon fiber, and can be formed by laser cutting.

[0116] As shown in FIG10 , the support member 103 is flush with the display panel 102 . Thus, when processing the support member 103 and the display panel 102 , the polarizer 1021 , the display panel 102 , the back film 1022 and the support member 103 can be bonded together, and then laser cutting and forming are used for integrated formation, which simplifies the process.

[0117] This embodiment does not limit the structure of the support member 103. In some embodiments, the support member 103 may be a laminated structure, including a flexible support member 1031 and a rigid support plate 1032 that are stacked.

[0118] In other embodiments, the support member 103 is a single-layer structure with fewer layers, which reduces the difficulty of laser cutting.

[0119] The embodiment of the present application discloses a display module and an electronic device, which electronic device includes: a functional device and a display module, and the display module includes: a stacked protective layer, a display panel and a support member, the display panel is provided with a through hole, the support member is provided with a first alignment hole, the through hole and the first alignment hole are connected, the through hole, the first alignment hole and the cover plate are arranged to form a first cavity, and the functional device is arranged in the first cavity. In some embodiments, the aperture of the first alignment hole is smaller than the aperture of the through hole, so that the support member expands outward toward the position where the functional device is located relative to the display panel to produce a cantilever. In other embodiments, the aperture of the first alignment hole is equal to the aperture of the through hole, and the alignment hole of the support member is flush with the edge of the through hole of the display panel. In this way, the support member can better support the display panel arranged above it, reduce the curvature of the display panel, reduce damage to the display panel, and improve the anti-extrusion ability of the opening area of ​​the display module.

[0120] The above is only a specific embodiment of the present application, but the scope of protection of this application is not limited to this. Any changes or substitutions within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
