Description

Support components, display modules and electronic devices

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on December 15, 2023, with application number 202311735254.3, and priority to the Chinese patent application with the invention name "Support component, display module and electronic device", all contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of display technology, and in particular to a supporting assembly, a display module and an electronic device. Background Art

[0003] At present, most curved screen electronic devices use flexible organic light emitting diode (OLED) displays. Usually, a flat display screen is first prepared, including a laminated glass cover (CG), optically clear adhesive (OCA), polarizer (POL), display touch layer (PANEL), back film (BF), silicone gel (SEPA) and the bottom support backplane. The edge area is bent by applying downward pressure on the edge to form a curved screen with curved edges. Usually, the support backplane is made of a layer of copper foil, which has poor extrusion resistance and is easily separated from the back film layer during bending preparation. It is not suitable for requirements that require bonding support with the back film. When the display screen is in use, it is difficult to effectively support structures such as the display touch layer. Summary of the Invention

[0004] The present application provides a support assembly, a display module, and an electronic device. By providing a connection interface between at least two adjacent support layers of at least two support layers, the at least two adjacent support layers are configured to produce relative displacement along the extension direction of the connection interface during bending, thereby enabling the support assembly to bend more effectively and preventing significant compression of the display screen. Furthermore, at least one of the at least two support layers has a Young's modulus within the range of 35 GPa to 400 GPa, thereby providing better support for the display screen and improving the overall compression resistance of the display screen during use.

[0005] In a first aspect, the present application provides a support assembly for supporting a display screen, comprising a central support area and side support areas located on the sides of the central support area, wherein the side support areas are located on one side of the curved area of ​​the display screen, and the side support areas include at least two support layers, wherein the at least two support layers are stacked, and at least two adjacent support layers of the at least two support layers have a connection interface, and the Young's modulus of at least one of the at least two support layers is in the range of 35 GPa to 400 GPa.

[0006] The present application makes the support assembly into a multi-layer structure, so that when the edge of the display screen is bent to form a curved screen, at least two support layers can be relatively displaced along the direction of extension of the connection interface, and the support assembly can bend better. Under the greater extrusion when the cover plate is bent inward, the clamping of the cover plate and the support assembly will not cause a large extrusion force on the display screen, preventing the display screen from being damaged by extrusion. In addition, the support assembly composed of at least two support layers, at least one layer of which has a Young's modulus in the range of 35Gpa to 400Gpa, is used to support the display screen of the display module, so that the display screen can have better strength during use, ensuring the overall anti-extrusion ability of the display screen when in use.

[0007] In one possible implementation, at least one of the at least two support layers is a metal layer. The metal layer can be made of materials such as copper and steel, both of which have good thermal conductivity. The support assembly is composed of a composite of layered copper and steel layers. This layered structure provides the support assembly with improved flatness and heat distribution. The support assembly can evenly transfer heat from other structures of the electronic device that contact the display screen (such as a printed circuit board) to the housing of the electronic device.

[0008] In one possible implementation, the at least two support layers include a first support layer and a second support layer connected in a stacked manner. The two support layers include a first support layer and a second support layer connected in a stacked manner. The material of one of the first support layer and the second support layer includes copper, and the material of the other layer includes steel. Copper has good ductility. When the first support layer is a copper layer, the contact between the copper layer and the display screen can be more closely attached to the surface of the display screen. There will be no gaps or even protrusions on the connecting surface between the copper layer and the display screen, thus preventing the display screen from being damaged by excessive stress in the gaps or protrusions. Steel has good hardness and low density. Under the premise of meeting the support strength requirements for the display screen, when the second support layer is a steel layer, it can be prepared into a thinner structure than the copper layer.

[0009] In one possible implementation, the at least two supporting layers further include a third supporting layer, the first supporting layer, the second supporting layer, and the third supporting layer are sequentially stacked and connected, and the third supporting layer and the first supporting layer are made of the same material. The first and third supporting layers disposed on the upper and lower surfaces of the second supporting layer are made of the same material, have the same thermal expansion coefficients, and have the same deformation magnitudes when thermally expanded. This allows the tensile forces or compressive forces exerted by the first and third supporting layers on the second supporting layer to offset each other, thereby preventing the second supporting layer from warping and deformation, thereby preventing the display screen from warping and deformation caused by warping and deformation of the support assembly, and preventing unnecessary warping of the display panel in the display screen due to warping and deformation of the support assembly, thereby improving the display quality of the display panel.

[0010] In one possible implementation, the material of the first supporting layer includes copper, the thickness of the first supporting layer is in the range of 0.003 mm to 0.02 mm, and the Young's modulus of the first supporting layer is in the range of 20 GPa to 110 GPa; the material of the second supporting layer includes steel, the thickness of the second supporting layer is in the range of 0.02 mm to 0.1 mm, and the Young's modulus of the second supporting layer is in the range of 150 GPa to 250 GPa; the material of the third supporting layer includes copper, the thickness of the third supporting layer is in the range of 0.003 mm to 0.02 mm, and the Young's modulus of the third supporting layer is in the range of 20 GPa to 110 GPa. The third supporting layer is adhered to the display screen side of the display module to effectively support and protect the display screen. The supporting component can withstand the extrusion force applied to the display module during use, thereby reducing the probability of damage to the display module. In addition, the thickness of the display screen will not be too large, which is conducive to the thin design of the electronic device.

[0011] In one possible implementation, the side support region further includes a first connecting layer, which is stacked with the at least two supporting layers. The first connecting layer is used to securely connect the display screen to the at least two supporting layers. One side of the first supporting layer in the support assembly can be attached to a side of the display screen facing away from the display panel via the first connecting layer, thereby providing support for the display screen.

[0012] In one possible implementation, the side support regions have a hole structure that is configured to reduce the Young's modulus of the side support regions. By reducing the structural strength of the side support regions at corresponding locations through the hole structure, the side support regions are more easily bent and deformed, allowing them to better adapt to bending and adhere closely to the curved region of the display module, thereby improving the overall structural stability of the display.

[0013] In one possible implementation, the hole structure includes at least one of a through hole and a blind hole provided in the side support region. The bottom wall of the blind hole is located in one of the at least two support layers, and the through hole penetrates the at least two support layers. A blind hole is a hole whose depth is less than the thickness of the support layer, where the depth of the hole is the depth of the blind hole along the thickness direction of the support layer. For example, in a three-layer support structure, a hole is formed on the outer surface of the third support layer facing away from the second support layer, and the hole does not penetrate the first support layer, thereby forming a blind hole structure in the support member. The at least two support layers provided with the blind hole structure are fixed to the side of the backplate facing away from the display panel via a first connecting layer, providing a secure connection to the display. A through hole is a hole that penetrates at least two support layers. In an example of a three-layer support structure, the through hole penetrates the first, second, and third support layers. The through hole can significantly reduce the structural strength of the side support region of the support member at the corresponding location, making the side support region more susceptible to bending and deformation.

[0014] The hole structure can also be a sleeve hole structure composed of holes with different diameters along the axial direction of the hole. The sleeve hole as a whole can be a through hole that penetrates the entire support layer, or it can be a blind hole structure that does not penetrate the support layer. The sleeve hole can include two sections along the thickness direction of the support layer. The inner diameters of the two sections of the hole structure along the extension direction of the support layer are different. The inner diameters of the two sections of the hole structure increase in the direction away from the back plate, so that the proportion of the hole structure in the area close to the display screen in the support component is smaller than the proportion of the hole structure in the area away from the display screen. The structural strength of the area close to the display screen of the support component is greater than the structural strength of the area away from the display screen. The support member with the blind hole and the display screen bonding area are strong and can better support the display screen. The structural strength of the area away from the display screen is relatively low, which is more conducive to bending the display screen in the direction away from the display screen during bending preparation.

[0015] In one possible implementation, the hole structure has an opening located on the outer surface of the support assembly, and the hole structure is configured to extend along the opening toward the display screen. This hole-forming method ensures that holes are not formed in the first connection layer or even the display screen, thereby improving the connection strength of the first connection layer to the first support layer and the backplane, and preventing damage to the display screen from the holes.

[0016] In one possible implementation, the at least two supporting layers include a first supporting layer and a second supporting layer, the first supporting layer being used to be bonded and connected to the display screen, and the edge of the first supporting layer being located inside the edge of the second supporting layer to form a step structure. Due to the formation of the step structure, the first connecting layer partially fills the space at the step structure, so that the curved outer wall surfaces on both sides of the first connecting layer and the first supporting layer are bonded. In addition, the degree of curvature of the display panel and the backplane layer is greater than the degree of curvature of the first supporting layer and the second supporting layer, so that when the display screen is bent, the degree of curvature of the supporting assembly is reduced. When the display screen is bent, the degree of curvature of the supporting assembly is reduced, thereby reducing the supporting squeezing force of the supporting assembly on the display screen and preventing the display panel from being damaged when bent.

[0017] In one possible implementation, the outer surface of the step structure is a curved surface, and the first and second supporting layers are smoothly transitioned at the junction. The first and second supporting layers are smoothly transitioned at the junction, so that the lower surface of the first supporting layer and the upper surface of the second supporting layer form a connected, integral curved surface. This curved transition step structure can avoid sudden stress changes during bending, effectively reducing the bonding pressure at the edges of the first and second supporting layers.

[0018] In one possible implementation, the support assembly further includes a vacuum chamber heat spreader, which is located on one side of the central support area; the vacuum chamber heat spreader includes a condensation layer, a vaporization layer and a heat conduction layer stacked and connected in sequence, and the vaporization layer has a channel therein, which is used to accommodate a cold medium.

[0019] One side of the vacuum chamber heat spreader can be fitted with one side of the support assembly, and the vacuum chamber heat spreader can be fixedly connected to the support assembly through processes such as brazing. The vacuum chamber heat spreader is designed to be retracted, that is, the outermost edge of the vacuum chamber heat spreader is located on the inner side of the outermost edge of the display module. The vacuum chamber heat spreader can avoid part of the bending area of ​​the display module, which can improve the bending ability of the screen edge and facilitate the bending preparation of the screen. When the support assembly bends, the vacuum chamber heat spreader avoids the bending area and does not apply a reverse force to the bent part, ensuring that the display screen and each supporting layer bend, and does not cause squeezing of the display panel when bending.

[0020] The vapor chamber is oriented toward the heat source (the electronic device's circuit board and the components mounted on it), transferring heat generated by the device during operation. The vapor chamber not only serves as a heat distribution structure but also provides the structural strength to support the display.

[0021] In one possible implementation, the condensation layer is made of copper, the vaporization layer is made of steel, and the heat-conducting layer is made of copper. A vapor chamber vapor chamber made of a combination of copper and steel can improve its overall rigidity compared to a vapor chamber vapor chamber made entirely of copper. Furthermore, the lower density of steel than copper improves rigidity while reducing the weight of the vapor chamber vapor chamber, thereby lowering manufacturing costs.

[0022] In the second aspect, the present application provides a support assembly, comprising a first support layer, a second support layer and a third support layer stacked in sequence, the first support layer, the second support layer and the third support layer all having a central support area and a side support area located on the side of the central support area, a channel is provided in the portion of the second support layer located in the central support area, the second support layer is located between the first support layer and the third support layer, the first support layer and the third support layer cover and close the channel, and the channel is used to accommodate a cold medium; a connection interface is provided between at least two adjacent support layers located in the side support area, and the two adjacent support layers are used to generate relative displacement along the extension direction of the connection interface when bent, and the Young's modulus of at least one support layer in the support assembly is in the range of 35Gpa to 400Gpa.

[0023] The support assembly of this application does not exert significant reverse extrusion force on the display screen during bending preparation; while the display screen is in use, the support assembly can support the display screen in the thickness direction. Furthermore, by providing channels on the second support layer to construct the support assembly into a vacuum chamber heat spreader structure, the support assembly not only ensures support for the display screen but also provides a heat spreader function, eliminating the need for a vacuum chamber heat spreader on one side of the support assembly. This simplifies the structure and space, facilitating the production of thinner electronic devices.

[0024] In a possible implementation manner, the first supporting layer, the second supporting layer, and the third supporting layer are all made of metal materials, and the first supporting layer and the second supporting layer are made of the same metal material.

[0025] The first supporting layer and the third supporting layer arranged on the upper and lower surfaces of the second supporting layer are made of the same material, and the first supporting layer and the third supporting layer have the same thermal expansion coefficient. The deformation amount of the first supporting layer and the third supporting layer during thermal expansion is also the same, so that the tensile force or extrusion force generated by the first supporting layer and the third supporting layer on the second supporting layer can offset each other, thereby avoiding warping deformation of the second supporting layer, thereby preventing warping deformation of the display screen caused by warping deformation of the support component, preventing unnecessary warping of the display panel in the display screen due to the warping deformation of the support component, and improving the display quality of the display panel.

[0026] In a third aspect, the present application provides a display module, comprising a display screen and a support assembly as described in any one of the above items, wherein the display screen comprises a cover plate, a polarizing film layer, a display panel and a back plate layer that are stacked and connected, and the display panel, the back plate layer and the support assembly are stacked and connected in sequence. The display module provided by the present application makes the support assembly into a multi-layer structure, so that when the edge of the display screen is bent to form a curved screen, at least two layers of the support layers can be relatively displaced along the direction in which the connection interface extends, and the support assembly can be bent better. Under the greater extrusion when the cover plate is bent inward, the clamping of the cover plate and the support assembly will not cause a large extrusion force on the polarizing layer and the display panel of the display screen, thereby preventing the polarizing layer and the display panel from being damaged by extrusion. Moreover, the Young's modulus of at least one of the at least two support layers is in the range of 35Gpa to 400Gpa, which is used to support the display screen of the display module, so that the display screen can have better strength during use, ensuring the overall anti-extrusion ability of the display screen when in use.

[0027] In a fourth aspect, the present application provides an electronic device comprising the display module described above, and further comprising a housing, wherein the housing and the outer edge of the display module are fixedly connected. In the present application, the support member of the display module is a layered structure in which at least two support layers are stacked. When the display screen is bent, the support member can bend more easily under the pressure of the display screen than a single-layer structure, thereby reducing the pressure of the support member on the polarizing layer and display panel in the display screen, preventing the polarizing layer and display panel from being damaged and affecting the imaging of the display screen, and improving the yield rate of the display screen. The Young's modulus of at least one of the at least two support layers is in the range of 35GPa to 400GPa, so that the support component can be easily bent while maintaining a high structural strength in the thickness direction, so that the display screen will not bend further when in use. The electronic device with this display module has good strength and anti-extrusion ability when in use. In addition, the support member also has a heat dissipation function, which can improve the heat dissipation capacity of the electronic device and ultimately increase the service life of the electronic device.

[0028] In one possible implementation, the electronic device includes a camera module, the support assembly has an opening, and a water inlet is located within the opening. The opening is located at an edge of the support assembly, and at least a portion of the camera module is located within the opening. The water inlet can overlap with the opening of the camera module of the electronic device along the thickness direction, eliminating the need for special drilling of holes in the support member to reserve space for the camera module. This can reduce the complex process associated with drilling holes and ensure the integrity, sealing, and reliability of the display module. BRIEF DESCRIPTION OF THE DRAWINGS

[0060] The present embodiment provides an electronic device 100, which may include, but is not limited to, a mobile phone, a tablet computer, a laptop computer, an ultra-mobile personal computer, a handheld computer, a walkie-talkie, an Internet-connected television, a wearable device, an in-vehicle device, a driving recorder, a security device, and other products with a display interface. The present embodiment does not impose any particular restrictions on the form of the electronic device.

[0061] For example, referring to FIG1 , the electronic device 100 in the embodiment of the present application is described using a curved screen mobile phone as an example. FIG1 is a perspective schematic diagram of the electronic device 100 provided in the embodiment of the present application. FIG2 is an exploded schematic diagram of a portion of the structure of the electronic device 100 provided in the embodiment of the present application. The electronic device 100 includes a display module 10 and a housing 20. The housing 20 is disposed on the display module 10. The housing 20 may include a middle frame and a back panel. The middle frame and back panel may be separate structures or may be an integrated structure, which is not specifically limited in this embodiment.

[0062] The display module 10 is mounted on the housing 20, wherein the housing 20 has a accommodating cavity, and components such as the circuit board, electronic components, camera module, processor and battery of the electronic device 100 can be installed in the accommodating cavity of the housing 20. The display module 10 covers the opening of the accommodating cavity of the housing 20, and the display module 10 and the housing 20 are sealed to form a sealed accommodating cavity, which protects the components in the accommodating cavity from water and dust. The housing 20 can be made of materials such as metal (such as aluminum alloy, titanium alloy and stainless steel), plastic (such as acrylonitrile-butadiene-styrene, polycarbonate and polypropylene) or glass (such as anti-glare glass). The housing 20 made of materials such as metal, plastic or glass can meet the requirements of wear resistance, impact resistance, corrosion resistance and aesthetics of the appearance of the electronic device 100.

[0063] In some possible implementations, the display module 10 can be a dual-curved screen, as shown in Figures 1 and 2, where the side edges of the display module 10 in the X direction and the opposite X direction are bent toward the side in the opposite Y direction. The display module 10 can also be a four-curved screen (not shown in the figure). The four-curved screen can refer to Figure 2, where the side edges of the display module 10 in the four directions of the X direction, the opposite X direction, the Z direction, and the opposite Z direction are all bent toward the side in the opposite Y direction to form a four-curved screen. In one embodiment, the four corners of the display module 10 are also bent toward the side in the opposite Y direction to form a curved display module 10 with all outer edges curved. This application does not specifically limit the number and length of the curved sides in the display module 10.

[0064] An embodiment of the present application provides a display module 10 that can be used in the electronic device described in the aforementioned embodiment. The display module 10 has two curved sides to form a dual-curved screen. Referring to FIG3 , FIG3 is a cross-sectional view of the display module 10 provided in the embodiment of the present application, wherein the cross-sectional direction can be referred to as the AA cross-sectional direction in FIG1 . The display module 10 includes a display screen 11 and a support assembly 12. Both the display screen 11 and the support assembly 12 are plate-shaped and are stacked.

[0065] The display screen 11 includes at least a cover plate 111, a second connecting layer 112, a polarizing layer 113, a display panel 114, and a backplane layer 115. The cover plate 111, the second connecting layer 112, the polarizing layer 113, the display panel 114, and the backplane layer 115 are stacked in sequence. The cover plate 111 may be a glass cover plate, which may be a transparent glass cover plate so that the display panel 114 can display through the glass cover plate. The second connecting layer 112 may be an optically clear adhesive (OCA) that connects the cover plate 111 and the polarizing layer 113 to form an integral structure and facilitates the passage of light emitted by the display panel 114 for display. The polarizing layer 113 may be a polarizer (POL) film that can eliminate reflections from the metal traces on the display panel 114 to improve the visibility of the display screen. The display panel 114 can be a display touch layer (PANEL). For example, a display layer and a touch layer are sequentially formed on a substrate to form a display panel with touch and display functions. The display panel 114 can be clamped between the polarizing layer 113 and the backplane layer 115, and can emit light as a display unit to realize the display of the display screen. At the same time, the display touch layer can also obtain the user's actions on the display screen, realize the acquisition of user actions, and convert them into electrical signals for processing to realize the interaction between the electronic device and the user. The backplane layer 115 can be a back film provided on one side of the display panel 114. The display touch layer is mostly a flexible layer. The display panel 114 is attached to the backplane layer 115, and the backplane layer 115 provides support for the display panel 114.

[0066] In one embodiment, the cover plate 111 can be located on the display surface side of the display screen 11. Thus, when the display module 10 is mounted on the electronic device 100, the cover plate 111 can protect the other layers of the display screen 11 while allowing light emitted by the display panel 114 to pass through. Materials for the cover plate 111 include, but are not limited to, glass and transparent polyimide. This application does not impose any specific restrictions on the material of the cover plate 111.

[0067] With the rapid development of display panel manufacturing technology for electronic devices, flexible screens are widely used as curved screens in electronic devices. Current flexible screen support structures primarily consist of a support assembly 12 positioned beneath the display screen 11. In one embodiment, the support assembly 12 includes a first connecting layer 121 and a support member 122. The first connecting layer 121 may be an adhesive layer that securely connects the support member 122 to the display screen 11. The support member 122 is typically copper foil, enhancing the screen's support and flexibility. The support assembly 12 has a certain structural strength to meet the required support strength for the display screen 11. However, for curved screens, when manufacturing the curved portion, the flat display screen 11 and support assembly 12 are typically stacked and fixed, and then the cover plate 111 of the display screen 11 is bent to form the curved screen structure. During the bending process, the cover plate 111 presses downward against the polarizing layer 113 and display panel 114, while the support assembly 12 provides support on the other side of the polarizing layer 113 and display panel 114. Under the pressure of the cover plate 111 and the support assembly 12, the polarizing layer 113 and the display panel 114 are easily damaged, especially the display panel 114, which can cause structural defects in the display module 10 and affect the display quality of the display module 10. In addition, in some scenarios (such as in high-energy consumption mode or when the external ambient temperature is too high), the heat dissipation capacity of the copper foil cannot meet the heat dissipation requirements of the electronic device.

[0068] The embodiment of the present application improves the support assembly 12 of the display module 10 , which will be described below with reference to the accompanying drawings.

[0069] Referring to FIG4 , FIG4 shows a schematic structural diagram of a support assembly 12 according to an embodiment of the present application. The support member 122 of the support assembly 12 includes at least two support layers. In one embodiment, this embodiment is described using a first support layer 1221 and a second support layer 1222 as an example. The first support layer 1221 and the second support layer 1222 are stacked and connected, and the first support layer 1221 and the second support layer 1222 are two independent support layers. The first support layer 1221 and the second support layer 1222 are fixedly connected to form an integral structure. It should be noted that the support assembly 12 has a central support area 12a and side support areas 12b located on the sides of the central support area 12a. The central support area 12a can support the flat area 11a of the display screen 11 shown in Figure 5. When the central portion of the display screen 11 is the flat area 11a, the central support area 12a can be flat. The side support areas 12b can support the curved area 11b of the display screen 11 shown in Figure 5. The side support areas 12b can be consistent in shape with the curved area 11b to support one side of the curved area 11b. In the embodiment of the present application, the central support area 12a in the support assembly can be a single-layer support layer structure, and the portion of the support layer extending to the side support areas 12b can be cut at the side using a process such as laser cutting to form a structure having at least two layers only in the side support areas 12b. In one embodiment, the central support area 12a and the side support area 12b can be composed of at least two support layers, as shown in Figure 4, each support layer can extend to the central support area 12a and the side support area 12b at the same time; or, at least two support layers are stacked and both extend to the central support area 12a and the side support area 12b, and one of the support layers can also be cut into another two-layer structure on the side of the side support area 12b by laser cutting or other processes, while the corresponding central support area 12a is a one-layer structure, all of which fall within the protection scope of the support component defined in this application.

[0070] In the embodiment of the present application, only the example that the middle support area 12a and the side support area 12b can be composed of at least two support layers is used for illustration. On the basis of ensuring that the side support areas include at least two support layers, there are multiple options for the number of layers of the middle support area 12a.

[0071] Refer to Figure 5, which shows a schematic diagram of the connection between the support assembly 12 and the display screen 11. The support assembly 12 also includes a first connecting layer 121, which is connected between the first supporting layer 1221 and the backplane layer 115 of the display screen 11. The first connecting layer 121 is used to securely connect the first supporting layer 1221 and the backplane layer 115. The first connecting layer 121 can be a layered structure made of an adhesive. Exemplary materials for making the first connecting layer 121 include pressure-sensitive adhesives such as rubber, polyacrylate, polyvinyl ether resin, polyurethane resin, or polyisobutylene. Alternatively, optical adhesives such as polyvinyl alcohol unsaturated polyester, epoxy adhesive, polyurethane adhesive, silicone gel, or light-curing adhesive can be used. In one possible embodiment, the first connecting layer 121 can be a layered structure made of silicone gel. Silicone gel has excellent adhesive properties and durability, providing reliable bonding during the assembly process between the first supporting layer 1221 and the backplane layer 115 of the display screen 11. At the same time, silicone gel is soft, and the first connection layer 121 made of silicone gel can also provide a certain buffering and shockproof effect for the display screen 11, thereby ensuring the stability and reliability of the display screen 11.

[0072] The display screen 11 includes a planar area 11a and a curved area 11b. The curved area 11b is adjacent to the planar area 11a and is curved toward the non-display surface of the display screen 11, as shown in FIG5 . In one embodiment, the display screen 11 may be a curved screen. The display screen shown in FIG5 may be applied to the curved screen electronic device 100 (mobile phone) shown in FIG1 .

[0073] The support assembly 12 is disposed on the non-display side of the display screen 11 and is stacked with the display screen 11. The support assembly 12 covers at least a portion of the curved region 11b. Within the flat region 11a of the display screen 11, the support assembly 12 closely adheres to the flat region 11a, providing support for the flat region 11a. Within the curved region 11b of the display screen 11, the support assembly 12 is curved and matches the angle of the curved region 11b, allowing the support assembly 12 to adapt to the shape of the curved region 11b and closely adhere to it, thereby providing support for the curved region 11b.

[0074] 4 and 5 , the support assembly 12 is located on the back side of the display screen 11 (the side opposite to the Y direction in FIG. 5 ). The stacked first support layer 1221 and the second support layer 1222 are fixedly connected via the first connecting layer 121 and the back panel layer 115 of the display screen 11. In one embodiment, the first support layer 1221 is connected to the first connecting layer 121, which is in turn connected to the back panel layer 115. The first connecting layer 121 may be an adhesive layer that can glue the first support layer 1221 and the back panel layer 115 together.

[0075] As shown in Figure 4, the first support layer 1221 and the second support layer 1222 are fixedly connected, and a connection interface 122a is provided between the first support layer 1221 and the second support layer 1222. When the edge portion of the support assembly 12 is bent from a flat plate shape to a curved shape, the first support layer 1221 and the second support layer 1222 can undergo a certain degree of relative displacement along the extension direction of the connection interface 122a (refer to the M direction shown in Figure 4, the M direction is consistent with the extension direction of the connection interface 122a). Referring to Figure 4, when the support component 12 is not bent, the first contact point 1221a of the first support layer 1221 (located on the connection interface 122a) and the second contact point 1222a of the second support layer 1222 coincide with each other; after the support component 12 is bent, the first contact point 1221a and the second contact point 1222a are misaligned to a certain extent along the connection interface 122a, so that the multi-layer structure of the support component 12 can bend more easily than the single-layer structure under the extrusion of the display screen 11, reducing the extrusion of the polarizing layer 113 and the display panel 114 in the display screen 11 by the support component 12, preventing the polarizing layer 113 and the display panel 114 from being damaged and affecting the imaging of the display screen, and improving the yield rate of the display screen preparation.

[0076] In one embodiment, after the support assembly 12 is bent, the display module 10 can be installed in an electronic device. Referring to Figures 4 and 5, the stacked first support layer 1221 and the second support layer 1222 provide support for the display screen 11 in the N direction (the N direction in the figure is parallel to the thickness direction of the first support layer 1221). During the use of the display module 10, the display screen 11 mainly squeezes the support assembly 12 along the N reverse direction, and the squeezing force during use is smaller than the squeezing force during the preparation of the curved screen. When the display screen is in use, the squeezing of the support assembly 12 by the display screen 11 does not cause relative sliding between the first support layer 1221 and the second support layer 1222 along the extended surface of the connection interface 122a.

[0077] In one embodiment, the Young's modulus of at least one of the at least two supporting layers in the support member 122 is in the range of 35 GPa to 400 GPa, so that the support assembly 12 can be easily bent while maintaining a high structural strength in the thickness direction, so that the display screen 11 will not be further bent during use. The Young's modulus of the first support layer 1221 and the second support layer 1222 (the Young's modulus described in this application is in the thickness direction, which will not be repeated hereafter) can be the same or different. The first support layer 1221 and the second support layer 1222 are fixedly connected to form an integrated structure to ensure that the support assembly 12 supports the display screen 11 in the thickness direction.

[0078] In one embodiment, the support assembly 12 may include two or more support layers, which are the same as the two support layers in the above embodiment, and at least two support layers are stacked in sequence along the thickness direction. In one embodiment, the support assembly 12 is a multi-layer structure composed of multiple support layers stacked in sequence along the thickness direction, and each support layer is bonded and connected. The thickness direction here is the Y direction in Figure 5. In one embodiment, when two or more support layers are stacked, the Young's modulus of at least one of the at least two support layers is in the range of 35GPa to 400GPa, so that after the support assembly 12 is bonded to the back side of the display screen 11, the support assembly 12 will not cause too much extrusion force on the display screen 11 during bending and forming, ensuring that the display screen 11 is not damaged when the bending area is prepared; and when the display screen is in use, the support assembly 12 provides certain support to the display screen 11 to prevent the display screen 11 from being damaged under certain stress.

[0079] The display module 10 provided in the embodiment of the present application is made into a multi-layer structure of the support assembly 12, so that when the edge of the display screen 11 is bent to form a curved screen, at least two layers of support layers can be relatively displaced along the direction in which the connection interface extends, and the support assembly 12 can be bent better. Under the large extrusion when the cover plate 111 is bent inward, the clamping of the cover plate 111 and the support assembly 12 will not cause a large extrusion force on the polarizing layer 113 and the display panel 114 of the display screen 11, thereby preventing the polarizing layer 113 and the display panel 114 from being squeezed and damaged. In addition, the support assembly 12 is composed of at least two layers of support layers, and the Young's modulus of at least one of the at least two layers of support layers is within the range of 35GPa to 400GPa, which is used to support the display screen 11 of the display module 10, so that the display module 10 can have good strength during use, thereby ensuring the overall anti-extrusion ability of the display module 10 when in use.

[0080] In some possible embodiments, at least one of the at least two support layers in the support assembly 12 can be a metal layer, and the material of the metal layer can include metals such as copper and steel. Referring to Figure 6, Figure 6 is a BB cross-sectional schematic diagram in Figure 5. The first support layer 1221 can be a copper layer made of copper material, and the second support layer 1222 can be a steel layer made of steel material. The copper layer and the steel layer are stacked, and the copper layer is bonded to the display screen 11 through the first connecting layer 121. Among them, the steel can be special stainless steel, which is a special stainless steel, referring to a high-alloy stainless steel containing high nickel, high chromium and high platinum, with high temperature resistance and corrosion resistance. Compared with 304, it has better high temperature resistance or corrosion resistance. The support assembly 12 is composed of a composite of layered copper layers and steel layers, and both the copper material and the steel material have good thermal conductivity. The layered structure enables the support assembly 12 to have better flatness and heat distribution effect. In this embodiment, the support assembly 12 can evenly conduct heat from other structures of the electronic device 100 that are in contact with the display module 10 (such as a printed circuit board) to the housing 20 of the electronic device 100 .

[0081] In one embodiment, the support assembly 12 is composed of a copper layer and a steel layer stacked together, and the total thickness of the first support layer 1221 and the second support layer 1222 is in the range of 0.023 mm to 0.14 mm. The thickness of the first support layer 1221 and the second support layer 1222 can be the same or different. After the first support layer 1221 and the second support layer 1222 are fixedly connected as one, the total thickness along the thickness direction can be in the range of 0.023 mm to 0.14 mm. Within this thickness range, the support assembly 12 can ensure a certain structural strength along the thickness direction. Moreover, the support assembly 12 within this thickness range can be attached to the back side of the display screen 11, and the display module 10 placed in the housing of the electronic device will not occupy a large thickness, forming an electronic device with a relatively thin thickness.

[0082] Table 1. Thickness, Young's modulus and density of the first support layer and the second support layer in this embodiment

[0083] Table 1 shows the thickness, Young's modulus and density parameters of each layer in the structure in which the first supporting layer 1221 is a copper layer and the second supporting layer 1222 is a steel layer in this embodiment.

[0084] In the embodiment of the present application, the first support layer 1221 can have a thickness of 0.01 mm, a Young's modulus of 50 GPa, and a density of 8.9 g / cm³. Copper has good ductility. When the first support layer 1221 is a copper layer, the copper layer and the display screen 11 can be more closely attached to the surface of the display screen 11. There will be no gaps or even protrusions at the connection surface between the copper layer and the display screen 11, thus preventing the display screen 11 from being damaged by excessive stress caused by the gaps or protrusions.

[0085] Steel has good hardness and low density. While meeting the support strength requirements for the display screen 11 as specified in this application, the second supporting layer 1222 can be made thinner when made of steel than when made of copper. In this embodiment, the second supporting layer 1222 can be 0.03 mm thick, with a Young's modulus of 193 GPa and a density of 7.9 g / cm³. Compared to 8.9 g / cm³ for copper, the second supporting layer 1222 is lighter at the same thickness.

[0086] The first support layer 1221 can be made of copper material, and the Young's modulus can be 50GPa; the second support layer 1222 can be made of steel material, and the Young's modulus can be 193GPa; the Young's modulus of the first support layer 1221 and the second support layer 1222 are both in the range of 35GPa to 400GPa, and the support component 12 can ensure a certain structural strength along the thickness direction.

[0087] It can be understood that the support assembly 12 can be a combination of at least two support layers stacked together, and therefore, the support assembly 12 has a variety of combinations. In this embodiment, a specific description is given by taking the support assembly 12 as an example in which two support layers are stacked together, one support layer being a copper plate and the other support layer being a steel layer. Specifically, referring to FIG4 , the support assembly 12 is prepared from two support layers, wherein the first support layer 1221 is a copper layer and the second support layer 1222 is a steel plate. In one embodiment, the first support layer 1221 can be a steel layer made of steel material, and the second support layer 1222 can be a copper layer made of copper material, and the first support layer 1221 made of steel material is fixedly connected to the backplane layer 115 by the first connecting layer 121 made of silicone gel material.

[0088] In one embodiment, the first support layer 1221 and the second support layer 1222 can be made of the same material. For example, the first support layer 1221 and the second support layer 1222 can both be copper layers, or steel layers, or other materials, to form a support assembly in which at least one of the at least two support layers has a Young's modulus within a range of 35 GPa to 400 GPa.

[0089] In some possible embodiments, the support assembly 12 may include two or more support layers. See Figures 7 and 8. Figure 7 shows a support assembly comprising three stacked support layers, and Figure 8 is a cross-sectional view taken along the CC axis of Figure 7. The support assembly 12 includes a first support layer 1221, a second support layer 1222, and a third support layer 1223 stacked in sequence. The upper and lower surfaces of the second support layer 1222 are covered with the first and third support layers 1221 and 1223, respectively. The first and third support layers 1221 and 1223 can be made of the same material, for example, copper. The upper and lower surfaces of the second support layer 1222 are symmetrical and have the same coefficient of thermal expansion, ensuring that the second support layer 1222 does not warp when heated or cooled. The coefficient of thermal expansion refers to the regularity with which the geometric properties of a material change with temperature due to thermal expansion and contraction. After the temperature changes, the length, area or volume of the first supporting layer 1221 and the third supporting layer 1223 changes. If the materials of the first supporting layer 1221 and the third supporting layer 1223 are different, the first supporting layer 1221 and the third supporting layer 1223 will generate different tensile forces or extrusion forces on the second supporting layer 1222 that is bonded together, causing the second supporting layer 1222 to warp and deform.

[0090] In this embodiment, the first supporting layer 1221 and the third supporting layer 1223 provided on the upper and lower surfaces of the second supporting layer 1222 are made of the same material, and the first supporting layer 1221 and the third supporting layer 1223 have the same thermal expansion coefficients. The deformation amounts of the first supporting layer 1221 and the third supporting layer 1223 during thermal expansion are also the same, so that the tensile force or the extrusion force generated by the first supporting layer 1221 and the third supporting layer 1223 on the second supporting layer 1222 can offset each other, thereby avoiding warping deformation of the second supporting layer 1222, thereby preventing the display screen 11 from being warped and deformed due to the warping deformation of the support component 12, and preventing the display panel 114 in the display screen 11 from being unnecessarily warped due to the warping deformation of the support component 12, thereby improving the display quality of the display panel 114.

[0091] Table 2. Thickness and Young's modulus range of the first support layer, the second support layer and the third support layer in this embodiment

[0092] In this embodiment, the material of the first supporting layer 1221 may be copper, and the thickness may be in the range of 0.003 mm to 0.02 mm. The material of the second supporting layer 1222 may be steel, and the thickness may be in the range of 0.02 mm to 0.1 mm. The material of the third supporting layer 1223 may be copper, and the thickness may be in the range of 0.003 mm to 0.02 mm.

[0093] In one embodiment, the overall thickness of the display support assembly 12, which is formed by sequentially stacking the first support layer 1221, the second support layer 1222, and the third support layer 1223, can be within a range of 0.26 mm to 0.14 mm. The display support assembly 12 is attached to one side of the display screen 11 of the display module 10, effectively supporting and protecting the display screen 11. Furthermore, the thickness of the display screen 11 is not excessively large, which facilitates a thin design for the electronic device 100. Furthermore, the Young's modulus of the first support layer 1221 can be within a range of 20 GPa to 110 GPa, the Young's modulus of the second support layer 1222 can be within a range of 150 GPa to 250 GPa, and the Young's modulus of the third support layer 1223 can be within a range of 20 GPa to 110 GPa. As a result, the Young's modulus of the entire support assembly 12 is within a range of 190 GPa to 470 GPa. The support assembly 12 can withstand the compressive forces applied to the display module 10 during use, thereby reducing the probability of damage to the display module 10.

[0094] In one embodiment, as shown in FIG5 , the first support layer 1221 and the second support layer 1222 made of a metal material can be composited by one or more processes such as electroplating, evaporation, magnetron sputtering, and hot pressing to securely connect the first support layer 1221 and the second support layer 1222 into a single unit. The first connecting layer 121 can be silicone gel (SEPA), and one side of the first support layer 1221 in the support assembly 12 can be bonded to the side of the backplane layer 115 in the opposite Y direction using the silicone gel.

[0095] In some possible embodiments, referring to Figures 9 and 10, the support assembly 12 includes a side support area 12b corresponding to the bending area 11b, and a hole structure 124 is provided on the side support area 12b. The hole structure 124 is used to reduce the thickness of the side support area 12b in a partial area (the area covered by the hole structure 124) along the thickness direction.

[0096] In this embodiment, the hole structure 124 is used to reduce the structural strength of the side support area 12b at the corresponding position, making the side support area 12b easier to bend and deform, so as to better adapt to bending and closely adhere to the curved area 11b of the display module 10, thereby improving the overall structural stability of the display module 10.

[0097] The hole structure 124 may be provided in the side support region 12 b by processes such as laser, etching, and punching.

[0098] In one embodiment, the openings of the hole structure 124 may be circular, elongated, waist-shaped, elliptical, or irregular in shape, etc. The hole structure 124 shown in FIG9 to FIG13 takes waist-shaped holes as an example.

[0099] In one embodiment, as shown in FIG. 10 , the hole structure 124 may be a blind hole. A blind hole refers to a hole whose depth is less than the thickness of the support layer. The depth of the hole is the depth of the blind hole along the thickness direction of the support layer.

[0100] In this embodiment, the support assembly 12 is configured as a stacked first support layer 1221, a second support layer 1222, and a third support layer 1223. The first support layer 1221 may be a copper layer, the second support layer 1222 may be a steel layer, and the third support layer 1223 may be a copper layer. The opening of the blind via is located on the outer surface of the support assembly 12 on the side opposite to the Y direction, and the blind via extends from the opening toward the display module.

[0101] In one embodiment, during preparation, the first supporting layer 1221, the second supporting layer 1222, and the third supporting layer 1223 can be fixed together as an integral structure, and holes can be opened on the outer surface of the third supporting layer 1223 on the side opposite to the Y direction. Laser engraving technology can be used to perforate the first supporting layer 1221, the second supporting layer 1222, and the third supporting layer 1223, which are made of metal materials, without penetrating the first supporting layer 1221, to form a blind hole structure in the support assembly 12. The at least two supporting layer structures with blind hole structures are then fixed to the side opposite to the Y direction of the backplane layer 115 in the display screen 11 via the first connecting layer 121 to form an integrated display screen structure.

[0102] In one embodiment, during preparation, the first supporting layer 1221, the second supporting layer 1222, and the third supporting layer 1223 can be fixed into an integral structure and fixed to the Y-direction-opposite side of the backplane layer 115 of the display screen 11 via the first connecting layer 121 to form an integrated display screen structure. A hole can then be opened on the outer surface of the Y-direction-opposite side of the third supporting layer 1223. Laser engraving technology can be used to perforate the first supporting layer 1221, the second supporting layer 1222, and the third supporting layer 1223, which are made of metal materials, without penetrating the first supporting layer 1221, thereby forming a blind hole structure in the support assembly 12.

[0103] In one embodiment, as shown in FIG11 , the hole structure 124 may be a through hole, which refers to a hole that passes through at least two supporting layers, such as the hole that passes through the first supporting layer 1221 , the second supporting layer 1222 and the third supporting layer 1223 in FIG11 .

[0104] In this embodiment, the support assembly 12 is configured as a stacked first support layer 1221, a second support layer 1222, and a third support layer 1223. The first support layer 1221 may be a copper layer, the second support layer 1222 may be a steel layer, and the third support layer 1223 may be a copper layer. The through-hole openings are located on the outer surface of the support assembly 12 on the side opposite to the Y direction, and the blind-hole openings are located on the outer surface of the third support layer 1223 on the side opposite to the Y direction.

[0105] In one embodiment, during fabrication, the first, second, and third supporting layers 1221, 1222, and 1223 can be fixed together as an integrated structure, and holes can be drilled on the outer surface of the third supporting layer 1223 on the side opposite to the Y direction. Laser engraving can be used to drill holes through the metal materials of the first, second, and third supporting layers 1221, 1222, and 1223, with the holes sequentially passing through the third, second, and first supporting layers 1223, 1222, and 1221, to form a through-hole structure in the support assembly 12. The at least two supporting layer structures with through-holes are then fixed to the side of the backplane layer 115 of the display screen 11 on the side opposite to the Y direction via the first connecting layer 121, forming a complete display screen structure. This drilling method ensures that holes are not formed in the first connecting layer 121 or even the display screen 11, improving the connection strength of the first connecting layer 121 to the first supporting layer 1221 and the backplane layer 115, and preventing damage to the display screen 11 from the holes.

[0106] In one embodiment, as shown in FIG12 , the hole structure 124 may be a sleeve hole, which refers to a hole having different diameters along the axial direction of the hole. The sleeve hole as a whole may be a through hole that penetrates the entire support layer, or a blind hole structure that does not penetrate the support layer, which is not limited in this embodiment. This embodiment takes the support assembly 12 as an example, comprising a first support layer 1221, a second support layer 1222, and a third support layer 1223 stacked in layers. The first support layer 1221 may be a copper layer, the second support layer 1222 may be a steel layer, and the third support layer 1223 may be a copper layer. The opening of the through hole is located on the outer surface of the support assembly 12 on the side opposite to the Y direction, and the opening of the blind hole is located on the outer surface of the third support layer 1223 on the side opposite to the Y direction.

[0107] In one embodiment, as shown in FIG12 , the holes of the hole structure 124 may include two sections along the thickness direction of the support layer (a direction substantially parallel to the Y direction in FIG12 ). The inner diameters of the two sections of the hole structure 124 along the extension direction of the support layer (a direction substantially parallel to the X direction in FIG12 ) are different. The inner diameters of the two sections of the hole structure 124 increase along the direction opposite to the Y direction, so that the hole structure 124 accounts for a smaller proportion of the area of ​​the support component 12 near the display screen 11 than the hole structure 124 accounts for the area of ​​the support component 12 near the display screen 11. The structural strength of the support component 12 near the display screen 11 is greater than the structural strength of the area away from the display screen 11. The support component 12 of this embodiment has greater strength in the area in contact with the display screen 11, providing better support for the display screen 11. The structural strength of the area away from the display screen 11 is relatively lower, making it more conducive to bending the display screen away from the display direction during bending preparation.

[0108] In one embodiment, during preparation, the first supporting layer 1221, the second supporting layer 1222, and the third supporting layer 1223 can be fixed to form an integrated structure, and a hole can be opened on the outer surface of the third supporting layer 1223 on the side opposite to the Y direction. Laser engraving technology can be used to perforate the first supporting layer 1221, the second supporting layer 1222, and the third supporting layer 1223 made of metal material to form a sleeve hole on the support assembly 12. The first connecting layer 121 is then fixed to the side opposite to the Y direction of the backplane layer 115 of the display screen 11 to form an integrated display screen structure.

[0109] In one embodiment, during preparation, the first supporting layer 1221, the second supporting layer 1222, and the third supporting layer 1223 can be fixed into an integral structure and fixed to the side of the backplane layer 115 in the display screen 11 along the anti-Y direction via the first connecting layer 121 to form a complete display screen structure. A hole can then be opened on the outer surface of the third supporting layer 1223 along the anti-Y direction. Laser engraving can be used to perforate the first supporting layer 1221, the second supporting layer 1222, and the third supporting layer 1223, which are made of metal materials, to form a sleeve hole structure on the support assembly 12.

[0110] In one embodiment, the hole structure 124 can be a combination of blind holes, through holes and sleeve holes. For example, referring to Figure 13, the hole structure can be a combination of blind holes and through holes, and blind holes and through holes can be respectively opened on the first supporting layer 1221, the second supporting layer 1222 and the third supporting layer 1223.

[0111] In one embodiment, as shown in FIG9 , the side support region 12b may be provided with a plurality of hole structures 124. The hole structures 124 may be at least one of blind holes, through holes, and sleeve holes. The plurality of hole structures 124 may be arranged at intervals along the extension direction of the side support region 12b (the Z direction in FIG9 ). In one embodiment, as shown in FIG12 , the plurality of hole structures 124 may also be arranged at intervals along the X direction shown in FIG12 .

[0112] The shapes, sizes, and layouts of the different hole structures 124 on the side support area 12b can be the same or different. A matching design can be made based on the bending process and the extrusion force received by the support assembly 12 during use, and this application does not impose any restrictions on this.

[0113] The multiple hole structures 124 described in this embodiment can adjust the structural strength of the side support area 12b by adjusting the proportion of the hole structure 124 on the side support area 12b to the overall area of ​​the side support area 12b, as well as parameters such as the depth and spacing distance of the hole structure 124 in the side support area 12b after the support component 12 and the display screen 11 are attached to each other, according to the extrusion force during the bending process and use. This ensures that the display panel 114 in the display screen 11 is not strongly squeezed by the support component 12 when bending, and that the display panel in the display screen 11 is supported by the support component 12 when in use and will not be further bent, thereby protecting the display panel 114 from damage during bending and use.

[0114] In some possible embodiments, the edge of the first supporting layer is retracted relative to the edge of the second supporting layer to form a stepped structure. Referring to Figure 14 , the outermost edges of the first supporting layer 1221 in the X-direction and the anti-X-direction are located inward of the outermost edges of the second supporting layer 1222 in the X-direction, with a first stepped structure 1224 defined between the first supporting layer 1221 and the second supporting layer 1222. The first stepped structure 1224 may be a stepped structure formed between the first supporting layer 1221 and the second supporting layer 1222. In this embodiment, the surface of the first stepped structure 1224 may be a circular arc transition.

[0115] In one embodiment, as shown in Figure 15, the first step difference structure 1224 can be a rounded structure, so that the first support layer 1221 and the second support layer 1222 have a smooth transition at the position of the first step difference structure, so that the lower surface of the first support layer 1221 and the upper surface of the second support layer 1222 are connected as one arc surface.

[0116] In one embodiment, the angle between the tangent line at any point on the arc surface and the extended surface of the second support layer 1222 is less than 30°. This angle can avoid excessive slope at the step structure position, and stress concentration will not be caused by the large step slope during the bonding process between the display screen and the support member. The first step structure 1224 with arc surface transition can avoid stress mutation during the bending process, effectively reducing the bonding pressure at the edge positions of the first support layer 1221 and the second support layer 1222. When the edge portion of the support assembly 12 is bent, the first support layer 1221 and the second support layer 1222 can undergo a certain degree of relative displacement along the extension direction of the connection interface 122a (refer to the M direction shown in Figure 4, the M direction is consistent with the extension direction of the connection interface 122a), thereby generating bonding pressure at the edge positions of the first support layer 1221 and the second support layer 1222. The first step structure 1224, with its curved transition, smoothly connects the edges of the first and second support layers 1221, 1222. Due to the smoothness of the curved transition, the relative displacement between the first and second support layers 1221, 1222 is more gradual, thereby reducing the generation of lamination pressure. Furthermore, during the bending process, the transition between the first and second support layers 1221, 1222 is gentle, resulting in a more uniform deformation distribution of the materials of the first and second support layers 1221, 1222, without sharp transitions or localized stress concentration areas, thereby reducing sudden stress concentrations.

[0117] In one embodiment, as shown in FIG16 , one side of the first supporting layer 1221 in the supporting assembly 12 can be bonded to the side of the backplane layer 115 in the opposite Y direction via a first connecting layer 121 made of silicone gel. Before bending, the display panel 114, backplane layer 115, first connecting layer 121, first supporting layer 1221, second supporting layer 1222, and third supporting layer 1223 are all flat. A first step structure 1224 is defined between the first supporting layer 1221 and the second supporting layer 1222 on both sides in the X direction and the opposite X direction. The outer surface of the first step structure 1224 is a curved surface.

[0118] When bent, the display panel 114, backplane layer 115, first connection layer 121, first support layer 1221, second support layer 1222, and third support layer 1223 all bend in the opposite Y direction on both sides of the X direction and the opposite X direction. Due to the formation of the first step structure 1224, the first connection layer 121 partially fills the space at the first step structure 1224, so that the curved outer wall surfaces on both sides of the first connection layer 121 and the first support layer 1221 are aligned. In addition, the degree of bending of the display panel 114 and backplane layer 115 is greater than the degree of bending of the first support layer 1221, the second support layer 1222, and the third support layer 1223. As a result, when the display screen is bent, the degree of bending of the support assembly 12 is reduced. When the display screen is bent, the degree of bending of the support assembly 12 is reduced, reducing the supporting and squeezing force of the support assembly 12 on the display screen 11, thereby preventing damage to the display panel 114 during bending.

[0119] The first step structure 1224 in this embodiment can be processed by one or a combination of etching, metal powder injection molding, laser engraving and other processes.

[0120] In one embodiment, as shown in FIG17 , the support assembly 12 can also be prepared by stacking three support layers in sequence, wherein the support layers include at least two copper layers with a steel layer located between the two copper layers. Specifically, the first support layer 1221 is a copper layer, the second support layer 1222 is a steel plate, and the third support layer 1223 is a copper layer. The first support layer 1221, the second support layer 1222, and the third support layer 1223 can be laminated using one or more processes such as electroplating, vapor deposition, magnetron sputtering, and hot pressing.

[0121] Further, referring to FIG17 , the upper surface of the second supporting layer 1222 covers the first supporting layer 1221. The outermost edge of the first supporting layer 1221 in the X-direction is located inward of the outermost edge of the second supporting layer 1222 in the X-direction. A first step structure 1224 is defined between the first supporting layer 1221 and the second supporting layer 1222. The lower surface of the second supporting layer 1222 covers the third supporting layer 1223, which is symmetrically arranged with the first supporting layer 1221. Thus, a second step structure 1225 is defined between the second supporting layer 1222 and the third supporting layer 1223.

[0122] The surfaces of the first step structure 1224 and the second step structure 1225 can both be right-angled, chamfered, or smoothly transitioned. In one embodiment, as shown in FIG17 , smooth transition structures are provided at both the first step structure 1224 and the second step structure 1225, and the surfaces of the first step structure 1224 and the second step structure 1225 are both smoothly transitioned curved surfaces.

[0123] In one embodiment, the first step difference structure 1224 and the second step difference structure 1225 can be processed by one or a combination of processes such as etching, metal powder injection molding, or laser engraving.

[0124] In some possible implementations, as shown in Figures 18 and 19 , the support assembly 12 described in this embodiment further includes a vapor chamber 125 located on one side of the central support region 12a. The vapor chamber 125 may not extend to the side support regions to prevent it from affecting the bending of the side support regions.

[0125] Specifically, referring to Figures 18 and 19 , the vacuum chamber vapor chamber 125 includes a first vapor chamber 1251, a second vapor chamber 1252, and a third vapor chamber 1253, which are sequentially spaced apart in the Y direction. The first vapor chamber 1251, the second vapor chamber 1252, and the third vapor chamber 1253 can be sealed together by welding or other means.

[0126] The first heat spreader 1251 has a super hydrophobic surface and serves as the condensation layer of the vacuum chamber heat spreader 125; the second heat spreader 1252 serves as the vaporization layer of the vacuum chamber heat spreader 125 and has a channel 1252a, which can be a capillary channel with a refrigerant medium flowing inside to distribute heat evenly over the entire vacuum chamber heat spreader 125; the third heat spreader 1253 has a super hydrophilic surface and serves as the heat conduction layer of the vacuum chamber heat spreader 125.

[0127] The vacuum chamber heat spreader 125 further includes a coating layer 1254. Similar to a brazing process, the welding material can be evenly laid on the outer surface of the overall structure formed by the stack of the first, second, and third heat spreaders 1251, 1252, and 1253. The welding material is then connected to the upper third support layer 1223 and cured by heating. On the one hand, the coating layer 1254 can wrap around the outer surface of the overall structure formed by the stack of the first, second, and third heat spreaders 1251, 1252, and 1253 to provide protection and sealing. On the other hand, the coating layer 1254 is fixedly connected to the third support layer 1223, thereby fixing the overall structure formed by the stack of the first, second, and third heat spreaders 1251, 1252, and 1253 to the overall structure formed by the stack of the first, second, and third support layers 1221, 1222, and 1223.

[0128] In one embodiment, as shown in FIG20 , a water inlet 1255 is provided on one side of the vapor chamber 125. The water inlet 1255 is connected to the channel 1252a (see FIG19 ) of the vapor chamber 125. A refrigerant medium can be injected into the channel 1252a through the water inlet 1255. The vapor chamber 125 is then vacuumed and sealed with the water inlet 1255 to obtain the vapor chamber 125. The water inlet 1255 of the vapor chamber 125 can overlap with the front camera opening of the electronic device along the thickness direction to avoid having to drill a new hole in the vapor chamber 125.

[0129] In addition, the third heat spreader 1253 of the vacuum chamber heat spreader 125 faces the side close to the heat source (the circuit board of the electronic device and the components arranged on the circuit board). The heat generated by the electronic device 100 during operation is conducted to the heat conductive layer of the vacuum chamber heat spreader 125. The coolant inside the vacuum chamber heat spreader 125 quickly absorbs the heat and vaporizes into steam. At this time, the volume of the steam rapidly expands due to the absorption of heat, and diffuses from the high-pressure area in the vacuum chamber heat spreader 125 to the low-pressure area (that is, the low-temperature area). In the process of moving to the low-pressure area, the steam quickly condenses into liquid and releases heat when it contacts the condensation layer with a lower temperature. The condensed water flows back to the heat conductive layer due to the capillary action of the microstructure of the inner wall of the cavity, completing a heat transfer cycle.

[0130] The vapor chamber 125, while serving as a heat dissipation structure, can also have corresponding structural strength to provide auxiliary support for the display screen 11. In one embodiment, during the preparation of a curved screen, the vapor chamber 125 will provide a reverse extrusion force to the display screen when it is bent. The vapor chamber 125 is designed to be retracted, that is, the outermost edge of the vapor chamber 125 is located inside the outermost edge of the display module. The vapor chamber 125 can avoid the partial curved area 11b of the display module, which can improve the bending ability of the screen edge and facilitate the preparation of the curved screen. Referring to Figures 18 and 19, the edges of the vapor chamber 125 in the X direction and the opposite X direction are located inside the edges of the support member 122 in the X direction and the opposite X direction; the edge of the vapor chamber 125 in the X direction is located on the opposite X side of the edge of each support layer in the X direction, and the edge of the vapor chamber 125 in the opposite X direction is located on the X direction side of the edge of each support layer in the opposite X direction. When the edges of each supporting layer bend toward the opposite direction Y, the vacuum chamber heat spreader 125 avoids the bending area and does not apply a reverse force to the bent part, ensuring that the display screen 11 and each supporting layer bend and does not cause squeezing to the display panel 114 during bending.

[0131] In one embodiment, first vapor chamber 1251 can be made of copper, second vapor chamber 1252 can be made of steel, and third vapor chamber 1253 can be made of copper. Vacuum chamber vapor chambers made of a combination of copper and steel can improve the overall stiffness of a vapor chamber vapor chamber compared to those made entirely of copper. Furthermore, the density of steel is lower than that of copper, which improves stiffness while reducing the weight of the vapor chamber vapor chamber and, consequently, lowers manufacturing costs.

[0132] In some possible embodiments, referring to Figures 21 and 22, the support assembly 12 described in this embodiment includes a first connecting layer 121 and a support member 122. The first connecting layer 121 may be an adhesive layer that securely connects the support member 122 to the display screen 11. The support member 122 includes at least two stacked supporting layers. In this embodiment, the support member 122 includes a first supporting layer 1221, a second supporting layer 1222, and a third supporting layer 1223. The first supporting layer 1221, the second supporting layer 1222, and the third supporting layer 1223 may all extend to the central support region 12a and the side support regions 12b, so that the first, second, and third supporting layers each have a central support region and side support regions located to the sides of the central support region. The central support region may be located on the flat side of the display screen, and the side support regions may be located on the curved side of the display screen.

[0133] The first support layer 1221 can be made of a metal material such as copper and serve as a condensation layer. The second support layer 1222 can be made of a metal material such as steel, and a channel 1252a is provided inside the portion of the second support layer 1222 located in the central support area. The channel 1252a can be a capillary channel with a refrigerant flowing therein to distribute heat evenly across the entire support member 122. The third support layer 1223 can be made of a metal material such as copper and serve as a heat conducting layer. In one embodiment, the portion of the second support layer 1222 located in the side support area may not have a channel for circulating the refrigerant to prevent the channel from deforming and clogging due to bending of the second support layer 1222.

[0134] In one embodiment, the third support layer 1223 can be made of the same material as the first support layer 1221, for example, both are copper layers. The upper and lower surfaces of the second support layer 1222 are structurally symmetrical and have the same thermal expansion coefficient, which can ensure that the second support layer 1222 does not warp when heated or cooled. The thermal expansion coefficient refers to the regular coefficient of change in the geometric properties of a material due to the thermal expansion and contraction effect as the temperature changes. When the temperature changes, the length, area, or volume of the first support layer 1221 and the third support layer 1223 change. If the first support layer 1221 and the third support layer 1223 are made of different materials, the first support layer 1221 and the third support layer 1223 will exert different tensile or compressive forces on the second support layer 1222 to which they are bonded, causing the second support layer 1222 to warp.

[0135] In one embodiment of the present application, the first supporting layer 1221 and the third supporting layer 1223 provided on the upper and lower surfaces of the second supporting layer 1222 are made of the same material, the first supporting layer 1221 and the third supporting layer 1223 have the same thermal expansion coefficient, and the deformation amount of the first supporting layer 1221 and the third supporting layer 1223 during thermal expansion is also the same, so that the tensile force or the extrusion force generated by the first supporting layer 1221 and the third supporting layer 1223 on the second supporting layer 1222 can offset each other, thereby avoiding warping deformation of the second supporting layer 1222, thereby preventing the display screen 11 from being warped and deformed due to the warping deformation of the support component 12, preventing the display panel 114 in the display screen 11 from being unnecessary warped due to the warping deformation of the support component 12, and improving the display quality of the display panel 114.

[0136] In one embodiment, at least two adjacent support layers in the side support region have a connection interface. For example, in the side support region, the first support layer 1221 and the second support layer 1222 have a connection interface, and the second support layer 1222 and the third support layer 1223 have a connection interface. When the two adjacent support layers are bent, they can produce relative displacement along the extension direction of the connection interface. The Young's modulus of at least one support layer in the support member 122 is in the range of 35 GPa to 400 GPa, so that the support assembly 12 is easy to bend while maintaining a high structural strength in the thickness direction, so that the display screen 11 will not be further bent during use. The Young's modulus of the first support layer 1221 and the second support layer 1222 (the Young's modulus described in this application is in the thickness direction, which will not be repeated hereafter) can be the same or different. After the first support layer 1221 and the second support layer 1222 are fixedly connected as one, the Young's modulus of at least one support layer is in the range of 35 GPa to 400 GPa to ensure that the support assembly 12 supports the display screen 11 in the thickness direction.

[0137] The first support layer 1221 and the third support layer 1223 of the present application are both made of copper material, and the second support layer 1222 is made of steel material. The Young's modulus of the second support layer 1222 is in the range of 35GPa to 400GPa. When the display screen 11 is bent, the support assembly 12 will not cause a large reverse extrusion force on the display screen 11; when the display screen 11 is in use, the support member 122 can support the display screen 11 in the thickness direction. In addition, by providing a channel 1252a on the second support layer 1222, the support member 122 is constructed into a vacuum chamber heat spreader structure. On the basis of ensuring that the support member 122 supports the display screen 11, the support member 122 can also perform a heat spreader function. There is no need to provide a vacuum chamber heat spreader on one side of the support member 122, which simplifies the structure and space and is conducive to the preparation of thinner electronic devices.

[0138] In one embodiment, support member 122 is retracted. As shown in Figures 21 and 22 , the outermost edge of support member 122 is located inboard of the outermost edge of the display module. This allows support assembly 12 to avoid the display module's partially curved area 11b, enhancing the display screen 11's ability to bend at the screen edge and facilitating screen curvature. As shown in Figures 21 and 22 , the edges of support member 122 in the X-direction and anti-X-direction are located inboard of the edges of support member 122 in the X-direction and anti-X-direction. The X-direction edge of vapor chamber 125 is located on the anti-X side of the X-direction edge of each supporting layer, and the anti-X-direction edge of vapor chamber 125 is located on the X-direction side of the X-direction edge of each supporting layer. When the edges of each supporting layer bend in the anti-Y direction, vapor chamber 125 avoids the bending area, preventing any counteracting force from the bending portion. This ensures that display screen 11 and each supporting layer bend without compressing display panel 114.

[0139] The support member 122 can be attached to the backplane layer 115 to act as a heat spreader for the vacuum chamber. Referring to FIG23 , when the support member 122 is retracted relative to the display screen 11, for a curved display screen, the angle of the support member 122 at the edge is in the range of 40° to 80°. Specifically referring to the enlarged view A of FIG23 , taking the third support layer 1223 as an example, the bending angle here refers to the angle α formed when the extension line of the planar support portion of the third support layer 1223 along the X direction intersects with the extension line of the tangent line at the outermost edge of the side support area of ​​the vacuum chamber heat spreader 125. The angle α is in the range of 40° to 80°. Referring to the enlarged view B of FIG23 , taking the third support layer 1223 as an example, the ratio of the arc length L2 of the side support area 12b to the arc length of the display panel 114 located in the curved area 11b of the display screen 11 is in the range of 85% to 94%. After the support member 122 retracts, the vapor chamber 125 avoids the curved area, preventing any counterforce from being applied to the curved portion. This ensures that the display screen 11 and the supporting layers bend smoothly without squeezing the display panel 114. Furthermore, this ensures that the support member 122 bends more smoothly, allowing for a wider range of bending angles. This provides the display module 10 with a wider field of view and greater viewing angle consistency, thereby reducing visual distortion, improving viewing comfort, and making the on-screen content more realistic.

[0140] In one embodiment, the thickness of the support member 122 can be in the range of 0.1 mm to 0.5 mm. In this embodiment, the thickness of the support member 122 can be 0.3 mm. This embodiment combines the support function with the heat dissipation function to provide a support assembly with a vacuum heat dissipation chamber. The support assembly 12 is directly attached to the display screen 11, which not only reduces the overall thickness of the electronic device, but also increases the heat dissipation area (increased by approximately 5 times).

[0141] In one embodiment, as shown in FIG24 , a water inlet 1255 is provided on one side of the support member 122. The water inlet 1255 is connected to the channel 1252a (see FIG22 ) of the support member 122. A refrigerant can be injected into the channel 1252a through the water inlet 1255. Subsequently, a vacuum is drawn and the water inlet 1255 is sealed to obtain a support assembly 12 having a vacuum chamber. The water inlet 1255 of the support member 122 can overlap with the front camera opening of the electronic device along the thickness direction to avoid having to drill a new hole in the support assembly 12.

[0142] An embodiment of the present application provides a display module 10, comprising a display screen 11 and a support assembly 12 as described in any of the above embodiments. The display screen 11 and the support assembly 12 are both in the form of a plate, and the display screen 11 and the support assembly 12 are stacked. The display screen 11 comprises a cover plate 111, a polarizing layer 113, a display panel 114 and a back plate layer 115 that are stacked together, and the support assembly 12 is attached to one side of the back plate layer 115 in the opposite direction of Y. The display screen 11 and the support assembly 12 are both in the form of a plate, and the display screen 11 and the support assembly 12 are stacked together. The support assembly 12 comprises a first connecting layer 121 and a support member 122, and the first connecting layer 121 is used to fix the support member 122 and the display screen 11. The support member 122 comprises at least two supporting layers for supporting the display screen 11.

[0143] In one embodiment, the support member 122 includes a first support layer 1221 and a second support layer 1222. The first support layer 1221 and the second support layer 1222 can both extend to the central support region 12a and the side support region 12b. The first support layer 1221 and the second support layer 1222 are fixedly connected, and a connection interface 122a is defined between the first support layer 1221 and the second support layer 1222 in the side support region 12b. When the side support region 12b of the support assembly 12 is bent, the first support layer 1221 and the second support layer 1222 can undergo a certain degree of relative displacement along the extension direction of the connection interface 122a (see the M direction shown in FIG. 4 , which is consistent with the extension direction of the connection interface 122a). Referring to Figure 4, when the support component 12 is not bent, the first contact point 1221a of the first support layer 1221 (located on the connection interface 122a) and the second contact point 1222a of the second support layer 1222 coincide with each other; after the support component 12 is bent, the first contact point 1221a and the second contact point 1222a are misaligned to a certain extent along the connection interface 122a, so that the multi-layer structure of the support component 12 can bend more easily than the single-layer structure under the extrusion of the display screen 11, reducing the extrusion of the polarizing layer 113 and the display panel 114 in the display screen 11 by the support component 12, preventing the polarizing layer 113 and the display panel 114 from being damaged and affecting the imaging of the display screen, and improving the yield rate of the display screen preparation.

[0144] The Young's modulus of at least one supporting layer in the support member 122 is within the range of 35 GPa to 400 GPa, allowing the support assembly 12 to be easily bent while maintaining a high structural strength in the thickness direction, thereby preventing the display screen 11 from further bending during use. The Young's modulus of the first supporting layer 1221 and the second supporting layer 1222 can be the same or different. After the first supporting layer 1221 and the second supporting layer 1222 are fixedly connected as a whole, the Young's modulus of at least one of the at least two supporting layers is within the range of 35 GPa to 400 GPa, ensuring that the support assembly 12 supports the display screen 11 in the thickness direction.

[0145] The display module 10 provided in the embodiment of the present application is made into a multi-layer structure of the support assembly 12, so that when the edge of the display screen 11 is bent to form a curved screen, at least two layers of support layers can be relatively displaced along the direction in which the connection interface extends, and the support assembly 12 can be bent better. Under the large extrusion when the cover plate 111 is bent inward, the clamping of the cover plate 111 and the support assembly 12 will not cause a large extrusion force on the polarizing layer 113 and the display panel 114 of the display screen 11, thereby preventing the polarizing layer 113 and the display panel 114 from being squeezed and damaged. In addition, the support assembly 12 is composed of at least two layers of support layers, and the Young's modulus of at least one of the at least two layers of support layers is within the range of 35GPa to 400GPa, which is used to support the display screen 11 of the display module 10, so that the display module 10 can have good strength during use, thereby ensuring the overall anti-extrusion ability of the display module 10 when in use.

[0146] An embodiment of the present application provides an electronic device 100 comprising the display module 10 described in the above embodiment, and further comprising a housing 20, the housing 20 being connected to the display module 10. In the present application, the display module 10 of the electronic device 100 comprises a support member 122 formed of at least two stacked support layers. The support member 122 is used to support the display screen 11 of the display module 10. When the electronic device 100 is pressed by the display screen 11, the support member 122 can bend more easily than a single-layer structure. This reduces the pressure exerted by the support member 12 on the polarizing layer 113 and display panel 114 in the display screen 11, prevents damage to the polarizing layer 113 and display panel 114, and improves the yield rate of the display module. The Young's modulus of at least one support layer in the support member 122 is within the range of 35 GPa to 400 GPa, enabling the support member 12 to bend easily while maintaining a high structural strength in the thickness direction, thereby preventing the display screen 11 from further bending during use. The electronic device 100 having the display module 10 has good strength and anti-extrusion capability when in use. In addition, the support member 122 also has a heat distribution function, which can improve the heat dissipation capability of the electronic device 100 and ultimately increase the service life of the electronic device 100.

[0147] In one embodiment, the electronic device 100 includes a camera module, which is arranged below the display surface of the display module 10, and light from outside the display module 10 can pass through the display module 10 to reach the camera module. The support component 12 has an opening, and a water injection port 1255 is provided in the opening. The opening is located at the edge of the support component 12, and at least part of the camera module is located in the opening. The position of the water injection port 1255 can be vertically overlapped with the position of the camera module along the thickness direction of the display module 10. By using the support member 122, there is no need to specially punch the support member 122 due to the reserved position for the camera module, which can reduce the complicated process flow caused by punching and ensure the integrity, sealing and reliability of the display module 10.
