Description

Technical Field

[0001] The embodiments of the present application relate to the display field, and in particular to a display module and an electronic device. Background Art

[0002] As the functions of display terminals, such as mobile phones, continue to diversify, a variety of devices for implementing different functions are integrated in the mobile phone, such as cameras, fingerprint sensors and other functional devices.

[0003] Unlike candy-bar phones, foldable modules are made of bendable materials with low hardness. When the user's fingernails or sharp objects squeeze the opening area of ​​the display module with functional devices from the front, the layers of the opening area of ​​the foldable display module bend and deform, resulting in failures such as black spots and bright spots. Therefore, improving the squeezing capacity of the opening area of ​​the display module is an urgent problem to be solved. Utility Model Content

[0004] 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 squeezing.

[0005] In order to achieve the above purpose, the embodiment of the present application adopts the following technical solution:

[0006] In the first aspect of the embodiment of the present application, a display module is provided, which is used in an electronic device, and the electronic device includes: a functional device, the display module includes: a protective layer, a display panel and a support member arranged in a stacked manner, the display panel is provided with a through hole, the support member is provided with a first alignment hole, the through hole is connected to the first alignment hole, the through hole, the first alignment hole and the cover plate are surrounded to form a first cavity, and the functional device is arranged in the first cavity; the aperture of the first alignment hole is less than or equal to the aperture of the through hole. Thus, when the aperture of the first alignment hole is less than the aperture of the through hole, the support member expands outward relative to the display panel toward the position where the functional device is located to generate 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, so that when the user presses the opening position, 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.

[0007] 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 high modulus and can play a supporting role, while restraining the deformation of the flexible support member to prevent it from producing irreversible deformation, and the flexible support member has better buffering performance, and can absorb the impact energy in the vertical direction 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 the 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, and the buffering performance of the film layer can be taken into account.

Thus, a bracket that is larger than the display panel or flush with the display panel is arranged below the support member, so that the display panel can be better supported. When the user presses the opening area on the surface, the display panel is supported by the support member and the bracket below, and the curvature is further reduced, thereby improving the anti-extrusion ability of the display module.

[0009] In an optional implementation, the support member further includes: a metal layer, the surface of the bracket close to the display panel includes: a first area and a second area, the first area is arranged around the functional device, the second area is arranged around the first area, the metal layer is arranged between the first area and the display panel, a third alignment hole is provided on the metal layer, the third alignment hole is connected to the second alignment hole, the metal layer is connected to the display panel through the first back glue, and the second area is connected to the display panel through the second back glue.

[0010] In an optional implementation, the bracket and the metal layer are integrally formed, thereby the bracket with supporting performance and the metal layer are integrally formed, further improving the anti-bending performance of the display module.

[0011] In an optional implementation, the aperture of the third alignment hole is smaller than or equal to the aperture of the through hole. Thus, a metal layer that is larger than the display panel or flush with the display panel is provided under the support member, so that the display panel can be better supported. When the user presses the opening area on the surface, the support member, the metal layer and the bracket under the display panel jointly support the display panel, and the curvature is reduced, thereby improving the anti-extrusion ability of the display module.

[0012] In an optional implementation, the aperture of the through hole is equal to the aperture of the first alignment hole, and the display panel and the support member are integrally cut and formed by laser. Thus, the apertures of the openings of the two structural members are the same, and they can be integrally cut and formed by laser, which reduces the difficulty of the process.

[0013] In an optional implementation, the display panel is foldable. Therefore, the display panel is a flexible display screen, which is easily deformed and damaged when pressed by a user. The present application can better protect the display panel and improve the anti-bending performance of the display panel by providing an outwardly extending or flush support member under the display panel.

[0014] 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.

[0015] In an optional implementation, the display module further includes: a polarizer and a back film, the polarizer is arranged between the display module and the protective layer, the back film is arranged between the display panel and the support, the polarizer and the back film are both provided with through holes, and the apertures of the through holes of the polarizer and the back film are equal to the aperture of the display panel. Thus, the through holes are provided on the polarizer and the back film, which facilitates the arrangement of functional devices.

[0029] The embodiment of the present application provides an electronic device. The electronic device can be a tablet computer, a mobile phone, an e-reader, a remote control, a personal computer (PC), a laptop, a personal digital assistant (PDA), a vehicle-mounted device, an Internet TV, a wearable device, a TV, and other products with a display interface, as well as smart display wearable products such as smart watches and smart bracelets. The embodiment of the present application does not impose any special restrictions on the form of the above-mentioned electronic devices. For the convenience of explanation, the following embodiments are all exemplified by taking the electronic device as a mobile phone as an example.

[0030] like Figure 1 As shown, 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.

[0031] The display module 10 is used to display images.

[0032] The middle frame 11 is located between the display module 10 and the housing 12. The surface of the middle frame 11 away from the display module 10 is used to install internal components such as a battery, a printed circuit board (PCB), a camera, and an antenna. After the housing 12 and the middle frame 11 are covered, the above internal components are located between the housing 12 and the middle frame 11.

[0033] For example, Figure 1 As shown, the middle frame 11 includes a carrying plate 110 and a frame 112 surrounding the carrying plate 110 .

[0034] Among them, printed circuit boards (PCB), cameras, batteries and other electronic devices can be arranged on the surface of the carrier plate 110 facing the housing 12. Among them, the camera is not shown in the figure. The housing 12 is connected to the middle frame 11 to form a receiving cavity for accommodating the above-mentioned PCB, camera, battery and other electronic devices. This can prevent external water vapor and dust from invading the receiving cavity and affecting the performance of the above-mentioned electronic devices.

[0035] The display module 10 can be Figure 1 The flexible printed circuit (FPC) shown passes through the carrier board 110 and is electrically connected to the PCB disposed on the carrier board 110. Thus, the PCB can transmit display data to the display module 10 to control the display module 10 to display images.

[0036] 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, and these layers can be parallel to each other. The plane where 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 distributed in layers in the Z direction.

[0037] In one implementation of the present application, an electronic device 1, such as Figure 2 As shown, it includes a display module 10 and a functional device 20. The display module 10 has a display area 100 for displaying an image, and a frame area 1001 located outside the display area 100. The functional device 20 is arranged in the display area 100 of the display module 10. The frame area 1001 is provided with a driving circuit for driving the display panel 102 to display an image, such as a source driving circuit, a gate driving circuit, etc.

[0038] 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 other devices.

[0039] The embodiment of the present application does not limit the structure of the display module 10 .

[0040] Figure 3 for Figure 2 The AA cross-sectional view of the module 10 is shown in FIG. Figure 3 As shown, the display module 10 at least includes: a cover plate 101 and a display panel 102 .

[0041] The display panel 102 has a display surface a1 where a display image can be seen and a back surface a2 opposite to the display surface a1, and the back surface a2 of the display panel 102 is close to the middle frame 11. The display surface a1 of the display panel is provided with a polarizer 1021, and the back surface a2 is provided with a back film 1022.

[0042] In a 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. Since an electroluminescent layer is provided in each light emitting sub-pixel in the OLED display panel, the OLED display panel can realize self-luminescence after receiving an operating voltage.

[0043] The cover plate 101 is located at the light-emitting side of the display panel 102 . The cover plate 101 may be, for example, a cover glass (CG), and the cover glass may have a certain toughness.

[0044] The cover plate 101 includes a first surface and a second surface that are opposite to each other. The first surface of the cover plate 101 is close to the display surface a1 of the display panel 102 .

[0045] In some embodiments of the present application, a protective layer 1011 is disposed on the surface of the cover plate 101 , and the protective layer 1011 is disposed on a side of the cover plate 101 away from the display panel 102 .

[0046] In some embodiments, Figure 3 As shown, 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 .

[0047] 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 may be connected to the middle frame 11 via the adhesive 104 .

[0048] In some embodiments, Figure 3 As shown, 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, 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.

[0049] Next reference Figure 3 , the apertures of the through holes on the display panel 102, the polarizer 1021, and the back film 1022 are the same. The aperture of the alignment hole of the support member 103 is larger than the aperture of the through holes on the display panel 102, the polarizer 1021, and the back film 1022. The apertures of the alignment holes of the back glue 104 and the middle frame 11 are larger than the aperture of the through holes on the display panel 102, the polarizer 1021, and the back film 1022.

[0050] like Figure 4 As shown in the figure, when the user's fingernail or sharp object squeezes the opening area from the front, the layers of the opening area of ​​the folding display module bend and deform, and the display panel produces black spots and bright spots. The failure force value is 3.5kgf, which corresponds to about 5000ppm (5000 parts per million) in the market. That is, failure occurs under a relatively low squeezing force, and the fault feedback ratio (FFR) is high. Therefore, improving the squeezing capacity of the opening area of ​​the display module is an urgent problem to be solved.

[0051] In order to improve the anti-extrusion performance of the display module 10 in the opening area, the embodiment of the present application provides an improved display module.

[0052] Figure 5 A schematic diagram of the structure of the first display module provided in an embodiment of the present application. Figure 6 This is a schematic diagram of the structure of the second display module provided in the embodiment of the present application. Figure 5 , Figure 6 As shown, 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 member 103, a back glue 104 and a middle frame 11 stacked along the z direction.

[0053] In some embodiments, the display panel 102 is an active matrix organic light emitting diode (AMOLED) display screen.

[0054] As a self-luminous display, the AMOLED display screen does not need a backlight module (BLM). Therefore, when the base substrate in the AMOLED display screen is made of a flexible resin material, such as polyethylene terephthalate (PET), the AMOLED display screen can have a bendable property.

[0055] The cover plate 101 and the protection layer 1011 can protect the display panel 102 and prevent the external environment from interfering with the display panel 102 .

[0056] like Figure 5 , Figure 6 As shown, no holes are provided on the cover plate 101 and the protection layer 1011 .

[0057] Next reference Figure 5 , Figure 6 The polarizer 1021, the display panel 102, and the back film 1022 are provided with through holes, and the support member 103, the back glue 104, and the middle frame 11 are provided with alignment holes. The polarizer 1021, the display panel 102, the through holes of the back film 1022, the support member 103, the back glue 104, and the alignment holes of the middle frame 11 and the cover plate 101 are surrounded by a first cavity, and the functional device 20 is arranged in the first cavity.

[0058] See also Figure 5 , Figure 6 , combined with Figure 3 , the alignment hole diameter of the support member 103 is less than or equal to the through hole diameter of the display panel 102. The through hole of the display panel 102 is used as the first through hole, the alignment hole of the support member 103 is used 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.

[0059] In some embodiments, the axes of the through hole and the first alignment hole coincide with each other, and the axes of the through hole and the first alignment hole coincide with the axis of the functional device 20. In this way, the functional device 20 can be arranged in the middle position between the through hole and the first alignment hole, thereby improving the optical performance of the functional device 20. At the same time, the through hole and the first alignment hole are arranged coaxially, so that the spacing between the inner wall of the support member 103 and the functional device 20, and the spacing between the inner wall of the display panel 102 and the functional device 20 are more uniform, thereby reducing the interference of the support member 103 or the display panel 102 on the functional device 20.

[0060] like Figure 5 As shown, 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 produce a cantilever. In this way, when the user presses the opening position, the support member 103 can better support the display panel 102 arranged thereon, 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.

[0061] like Figure 6 As shown, 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 thereon, 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.

[0062] in, Figure 6 and Figure 5 In comparison, the size of the support member 103 is smaller, and the support member 103 and the display panel 102 are flush. When processing the support member 103 and the display panel 102, the support member 103 and the display panel 102 can be attached together and then integrally cut by laser, which simplifies the process.

[0063] 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.

[0064] The support member 103 is disposed on a side of the display panel 102 away from the cover plate 101 .

[0065] The embodiment of 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 arranged on a side of the flexible support member 1031 away from the display panel 102.

[0066] 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.

[0067] The material of the rigid support plate 1032 includes: metal, carbon fiber and other materials with high modulus.

[0068] Thus, the support member 103 includes a flexible support member 1031 and a rigid support plate 1032. When the rigid support plate 1032 and the flexible support member 1031 are arranged together, the rigid support plate 1032 has a higher modulus and can play a supporting role. At the same time, it constrains the deformation of the flexible support member 1031 to prevent it from producing irreversible deformation. The flexible support member 1031 has better buffering performance and can absorb the impact energy in the vertical direction through appropriate deformation, and its deformation is controlled within the controllable range of the rigid support plate 1032. The rigid support plate 1032 and the flexible support member 1031 have a significant synergistic attenuation effect on the 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 scenes such as rapid bending. The terminal device provided with the support member 103 can have good bending performance. When bending occurs, the lower limit of the buckling deformation is increased, and the buffering performance of the film layer can be taken into account.

[0069] like Figure 5 , Figure 6 As shown, the apertures of the through holes on the display panel 102 , the polarizer 1021 , and the back film 1022 are the same, and are all larger than the aperture of the alignment holes of the support member 103 .

[0070] Therefore, in the present application, a support member 103 is arranged 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.

[0071] In some embodiments, the display module 10 further includes: a bracket, the bracket 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.

[0072] For example, in the present application, the support may be Figure 5 , Figure 6 The middle frame 11 shown is provided with a second alignment hole for accommodating the functional device 20 .

[0073] The embodiment of the present application does not limit the aperture of the second alignment hole. In some embodiments, the aperture of the second alignment hole is less than or equal to the aperture of the display panel 102. In this way, in the present application, a bracket that is larger than the display panel 102 or flush with the display panel 102 is provided under the support member 103, which can better support the display panel 102. When the user presses the opening area on the surface, the support member 103 and the bracket are jointly supported under the display panel 102, and the curvature is further reduced, thereby improving the anti-extrusion ability of the display module.

[0074] 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 through the adhesive 104.

[0075] In some embodiments, an alignment hole is also provided on the adhesive backing 104. The embodiment of the present application does not limit the aperture of the alignment hole on the adhesive backing 104, and the aperture of the alignment hole on the adhesive backing 104 can be maximized. For example, the alignment hole of the adhesive backing 104 can be larger than or equal to the alignment hole with the larger aperture of the second alignment hole and the third alignment hole. In this way, the adhesive backing 104 can be retracted with the support member 103 and the bracket, or flush with the alignment hole with the larger aperture, so as to prevent the adhesive backing 104 from being exposed to air or dust.

[0076] To further improve the anti-extrusion performance of the display panel, in some embodiments, such as Figure 7 , Fig. 9 As shown, 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.

[0077] The third alignment hole can be used together with other alignment holes to set the functional device 20 .

[0078] In this embodiment, by disposing the metal layer 105 between the support member 103 and the middle frame 11 , the display panel 102 can be better supported, thereby improving the anti-extrusion capability of the display panel.

[0079] In some embodiments, Figure 7 , Fig. 9 As shown, 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 .

[0080] 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, such as Fig. 9 As shown, the middle frame 11 and the metal layer 105 are integrally formed.

[0081] The embodiment of the present application does not limit the aperture of the third alignment hole. In some embodiments, the aperture of the third alignment hole can be smaller than or equal to the aperture of the display panel 102 .

[0082] Therefore, in the present application, a metal layer 105 is arranged 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.

[0083] Combine the following Figure 5 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.10 The display module involved in this application is described.

[0084] like Figure 5 As shown, 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 member 103, a back glue 104 and a middle frame 11 stacked along the z direction.

[0085] There are no holes on the cover plate 101 and the protection layer 1011 .

[0086] The polarizer 1021, the display panel 102, and the back film 1022 are provided with through holes, and the support member 103, the back glue 104 and the middle frame 11 are provided with alignment holes. The polarizer 1021, the display panel 102, the through holes on the back film 1022, the support member 103, the back glue 104 and the alignment holes of the middle frame 11 and the cover plate 101 are surrounded by a first cavity, and the functional device 20 is arranged in the first cavity.

[0087] Next reference Figure 5 , the diameter of the alignment hole of the support member 103 is less than or equal to the diameter of the through hole of the display panel 102. The through hole of the display panel 102 is used as a through hole, and the alignment hole of the support member 103 is used 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.

[0088] In some examples of this embodiment, the axes of the through hole and the first alignment hole can be made to coincide, and the axes of the through hole and the first alignment hole can coincide with the axis of the functional device 20. In this way, the functional device 20 can be arranged in the middle position between the through hole and the first alignment hole, thereby improving the optical performance of the functional device 20. At the same time, the through hole and the first alignment hole are arranged coaxially, so that the spacing between the inner wall of the support member 103 and the functional device 20, and the spacing between the inner wall of the display panel 102 and the functional device 20 are more uniform, thereby reducing the interference of the support member 103 or the display panel 102 on the functional device 20.

[0089] See also 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 generate a cantilever. In this way, when the user presses the opening position, the support member 103 can better support the display panel 102 arranged thereon, 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.

[0090] 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.

[0091] 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 back film 1022 have the same aperture, which is larger than the alignment hole aperture of the support member 103 .

[0092] Therefore, in the present application, a support member 103 is arranged 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.

[0093] 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 arranged on a side of the flexible support member 1031 away from the display panel 102.

[0094] The flexible support member 1031 and the rigid support plate 1032 in the support member 103 are arranged alternately. The rigid support plate 1032 has a higher modulus and can play a supporting role. At the same time, it can restrain the deformation of the flexible support member 1031 and prevent it from producing irreversible deformation. The flexible support member 1031 has better buffering performance and can absorb the impact energy in the vertical direction through appropriate deformation, and its deformation is controlled within the controllable range of the rigid support plate 1032. The rigid support plate 1032 and the flexible support member 1031 have a significant synergistic attenuation effect on the 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 scenes such as rapid bending. The terminal device equipped with the support member 103 can have good bending performance. When bending occurs, the lower limit of the buckling deformation is increased, and the buffering performance of the film layer can be taken into account.

[0095] In some embodiments, the display module 10 further includes: a middle frame 11, the middle frame 11 is arranged on a side of the support member 103 away from the display panel 102, the middle frame 11 and the support member 103 are connected, and the middle frame 11 is provided with a second alignment hole, for example, and the second alignment hole is connected to 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.

[0096] The embodiment of the present application does not limit the aperture of the second alignment hole. In some embodiments, the aperture of the second alignment hole is less than or equal to the aperture of the display panel 102. In this way, in the present application, a bracket that is larger than the display panel 102 or flush with the display panel 102 is provided under the support member 103, which can better support the display panel 102. When the user presses the opening area on the surface, the support member 103 and the bracket are jointly supported under the display panel 102, and the curvature is further reduced, thereby improving the anti-extrusion ability of the display module.

[0097] 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 through the adhesive 104.

[0098] In some embodiments, an alignment hole is also provided on the adhesive backing 104. The embodiment of the present application does not limit the aperture of the alignment hole on the adhesive backing 104, and the aperture of the alignment hole on the adhesive backing 104 can be maximized. For example, the alignment hole of the adhesive backing 104 can be larger than or equal to the alignment hole with the larger aperture of the second alignment hole and the third alignment hole. In this way, the adhesive backing 104 can be retracted with the support member 103 and the bracket, or flush with the alignment hole with the larger aperture, so as to prevent the adhesive backing 104 from contacting with air or dust.

[0099] See also Figure 6 , combined with 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 overlap. In this way, when the user presses the opening position, the support member 103 can well support the display panel 102 arranged thereon, 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.

[0100] Therefore, compared with the first embodiment, the size of the support member 103 is smaller.

[0101] 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.

[0102] 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 for integrated cutting, which simplifies the process.

[0103] 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 laminated.

[0104] In other embodiments, the support member 103 is a single-layer structure with fewer layers, which reduces the difficulty of laser cutting.

[0105] See also Figure 7 , combined 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.

[0106] The third alignment hole can be used together with other alignment holes to accommodate the functional device 20 .

[0107] In this embodiment, by disposing the metal layer 105 between the support member 103 and the middle frame 11 , the display panel 102 can be better supported, thereby improving the anti-extrusion capability of the display panel.

[0108] In some embodiments, Figure 7 As shown, 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 .

[0109] The embodiment of the present application does not limit the aperture of the third alignment hole. In some embodiments, the aperture of the third alignment hole can be smaller than or equal to the aperture of the display panel 102 .

[0110] Therefore, in the present application, a metal layer 105 is arranged 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.

[0111] like Figure 8 As shown, Figure 7 The display module shown is subjected to an extrusion test. During extrusion, the support member 103 under the display panel 102 can well support the display panel 102, preventing the display panel 102 from being in a cantilever beam bending state. The failure force value of the display panel 102 producing black spots and broken bright spots is increased from 3.5kgf to 6.5kg, thereby improving the anti-extrusion ability of the opening area of ​​the display module.

[0112] See also Fig. 9 , combined with Figure 7 The middle frame 11 and the metal layer 105 are integrally formed. Thus, a plurality of components with supporting performance are integrally formed, further improving the anti-bending performance of the display module.

[0113] 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.

[0114] like Fig.10 As shown, 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 attached together, and then integrally cut and formed by laser, which simplifies the process.

[0115] 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 laminated.

[0116] In other embodiments, the support member 103 is a single-layer structure with fewer layers, which reduces the difficulty of laser cutting.

[0117] 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, wherein the display module includes: a stacked protective layer, a display panel and a support member, wherein a through hole is provided on the display panel, and a first alignment hole is provided on the support member, wherein the through hole is connected to the first alignment hole, and the through hole, the first alignment hole and the cover plate are arranged to form a first cavity, wherein the functional device is arranged in the first cavity, and 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 generate a cantilever, and 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, so that the support member can better support the display panel arranged thereon, 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.
