Description

Technical Field

[0001] This application belongs to the field of display technology, and in particular relates to a display module and a display device. Background Technology

[0002] In display electronic devices, the display module is fixed to the mid-frame, motherboard, and other core components through precise assembly relationships. To ensure structural stability and prevent screen damage due to pressure, spacers are typically placed in the assembly gaps between these components. Spacers play a crucial role in maintaining the flatness of the display module, controlling the overall thickness tolerance, and dispersing external impact energy.

[0003] Many related technologies employ spacers with uniform hardness, a single structure, and fixed dimensions. These spacers have the following technical limitations: 1. Dynamic loads such as heat generation during mobile phone operation, ambient temperature changes, and daily vibrations and drops can cause slight fluctuations in the installation gaps between components. Fixed-size rigid spacers cannot adaptively compensate for these fluctuations. When the gaps increase, the support fails and abnormal noises occur. When the gaps decrease, excessive pre-pressure on the screen results in display defects such as bright spots and water ripples.

[0004] 2. The assembly tolerances vary between different models and batches. To achieve the best support effect, the size of the gasket needs to be customized for each type of situation, which prolongs the design verification cycle and increases the cost of mold development and material management, thus restricting the versatility of production.

[0005] 3. Under transient impacts such as drops, rigid gaskets cannot effectively absorb energy, and stress is forcibly transferred to the brittle display module, which can easily lead to screen breakage or connector damage; moreover, frequent stress concentration can also cause fatigue fracture risk to the gasket itself and its connecting structure. Summary of the Invention

Detailed Implementation

[0036] In portable electronic devices such as mobile phones, the display module is fixed to the mid-frame, motherboard, and other core components through precise assembly. To ensure structural stability and prevent screen damage from pressure, spacers are typically placed in the assembly gaps between these components. These spacers play a crucial role in maintaining the flatness of the display module, controlling the overall thickness tolerance, and dispersing external impact energy.

[0037] The commonly used technologies employ spacer structures with uniform hardness, homogeneous structure, and fixed dimensions. However, in practical applications, such fixed-size spacers exhibit significant technical limitations: 1. Poor Dynamic Adaptability: During use, mobile phones expand and contract due to processor heat or changes in ambient temperature, and inevitably face vibration and accidental drops during daily carrying. These dynamic conditions cause minute but critical fluctuations in the installation gaps between components. Fixed-size spacers cannot compensate for this, potentially causing support failure (when the gap increases) or excessive pre-pressure on the screen (when the gap decreases). The former can easily lead to vibration and abnormal noise, while the latter may cause display quality problems such as bright spots or water ripples on the screen.

[0038] 2. Insufficient design flexibility and economy: Due to assembly tolerances between different mobile phone models, and even different batches of the same model, precise dimensions of the Spacer often need to be customized for each specific situation to achieve the best support effect. This not only increases the design verification cycle, but also increases the cost of mold development and material management, and reduces production versatility.

[0039] 3. Poor impact resistance and structural reliability: Under transient impact loads such as equipment drops, the rigid Spacer cannot effectively absorb impact energy. Stress will be rigidly transferred to the brittle display module through the Spacer, which can easily lead to screen cracking or damage to internal connectors. At the same time, frequent stress concentration can also easily cause fatigue fracture of the Spacer itself or its connecting structure.

[0040] Based on the above considerations, this application aims to at least solve one of the technical problems existing in the prior art. To this end, this application proposes a display module and display device that improves the compensation capability of the support components within the display module to cope with dynamic working conditions, provides better versatility for different product models, and has stronger impact resistance.

[0041] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0042] The following is for reference. Figures 1-14 This application describes a display module and a display device according to embodiments thereof.

[0043] Please see Figure 1 and Figure 2 This application provides a display module 100, including a display panel PNL, a first back film BF1, a second back film BF2, a connecting layer SCF, and a support member 10. The display panel PNL includes a display area PNL1, a bonding area PNL2, and a bending area PNL3 located between the display area PNL1 and the bonding area PNL2. The bending area PNL3 is bent so that the bonding area PNL2 is located on the backlight side of the display area PNL1. The first back film BF1 is disposed on the backlight side of the display area PNL1. The second back film BF2 is disposed on the side of the bonding area PNL2 facing the display area PNL1. The connecting layer SCF is disposed between the first back film BF1 and the second back film BF2. The support member 10 is disposed between the connecting layer SCF and the second back film BF2. The support member 10 includes a first support part 1, a second support part 2 and a connecting part 3. The first support part 1 abuts against the connecting layer SCF, the second support part 2 abuts against the second back film BF2, and the connecting part 3 connects the first support part 1 and the second support part 2 to change the distance between the first support part 1 and the second support part 2 along the thickness direction of the display panel PNL.

[0044] The display panel PNL is used to implement image display functions.

[0045] The display area PNL1 is the region within the display panel PNL used for actively emitting light to display images. It contains multiple data lines, scan lines, and light-emitting devices arranged in an array. In some examples, the light-emitting devices in the display panel PNL can be at least one of the following: Organic Light Emitting Diode (OLED), Liquid Crystal Display (LCD), Quantum Dot Organic Light Emitting Diode (QD-OLED), Quantum Dot Light Emitting Diode (QLED), and Micro-LED. All of these light-emitting devices can be fabricated using a flexible substrate.

[0046] The bonding area PNL2 is the region in the display panel PNL used to bond driver chip ICs or flexible circuit boards. It contains multiple bonding pads, through which the driver chip ICs or flexible circuit boards are electrically connected to the signal lines within the display panel PNL. The bending area PNL3 connects the display area PNL1 and the bonding area PNL2. It contains multiple bridging signal lines, which electrically connect the signal lines within the display area PNL1 to the bonding pads in the bonding area PNL2.

[0047] The bending area PNL3 is bent under the action of external force, causing the bonding area PNL2 to be folded to the backlight side of the display area PNL1, thereby reducing the projected area of ​​the display panel PNL in the thickness direction, which is beneficial to realizing the narrow bezel design of the display device 1000.

[0048] The thickness direction of the display panel PNL refers to the direction perpendicular to the light-emitting surface of the display panel PNL. This direction is a relative orientation. With the display panel PNL in a flat and unfolded state as a reference, the direction facing the light-emitting surface of the display area PNL1 is upward, and the backlight side is downward. The thickness direction is the up-down direction.

[0049] The first back film BF1 is attached to the backlight side surface of the display area PNL1. The first back film BF1 is used to provide structural support and protection for the backlight side of the display area PNL1, preventing cracks or damage to the display area PNL1 due to external forces during bending or use.

[0050] The first backsheet (BF1) can be made of polyimide, polyethylene terephthalate, polyethylene naphthalate, or other insulating film materials with high flexibility and certain mechanical strength. The first backsheet (BF1) also prevents water and oxygen from corroding the light-emitting devices and signal lines inside the display panel PNL from the backlight side, thus providing encapsulation and protection. In some embodiments, the first backsheet (BF1) can be adhered to the backlight-side surface of the display area PNL1 using optically transparent adhesive or pressure-sensitive adhesive layers.

[0051] The second back film BF2 is attached to the surface of the bonding area PNL2 facing the display area PNL1. It should be noted that after the bending area PNL3 is bent, the bonding area PNL2 is folded to the backlight side of the display area PNL1. At this time, the surface of the bonding area PNL2 that was originally facing away from the display area PNL1 is now facing the display area PNL1 after bending, and the second back film BF2 is attached to this surface.

[0052] The second back film BF2 provides protection for the bonding area PNL2 during bending, preventing damage to the bonding area PNL2 and its internal bonding pads, driver chip IC, or flexible circuit board during bending or long-term use. The second back film BF2 can be made of the same or different material as the first back film BF1, such as a polyimide film. In some embodiments, the second back film BF2 and the first back film BF1 can be integrally formed in the same process step. Before bending the display panel PNL, the back film of the bending area PNL3 is removed, thereby separating and forming the first back film BF1 and the second back film BF2, reducing stress concentration in the bending area PNL3.

[0053] The connecting layer SCF is disposed between the first back film BF1 and the second back film BF2. The connecting layer SCF is used to fix the support member 10 to the display panel PNL, and at the same time structurally connect the first back film BF1 and the second back film BF2, so that the force borne by the display panel PNL can be transmitted to the support member 10 through the connecting layer SCF.

[0054] In some examples, the connecting layer SCF can be a cleanroom foam composite film. A cleanroom foam composite film is a multi-layered composite structure, typically comprising an adhesive layer, a buffer layer, and a heat dissipation layer stacked sequentially. The adhesive layer can be a mesh adhesive, which provides adhesion and air release while maintaining flexibility, thus not affecting the flexible design of the display module 100. The buffer layer can be foam, which provides cushioning and absorbs external impact energy. The heat dissipation layer can be a metallic material such as copper foil or aluminum foil, serving a heat dissipation function. The cleanroom foam composite film may also include a polyimide layer, which provides reinforcement and increases the reliability of the connecting layer SCF. In some embodiments, the polyimide layer can be replaced by a graphite layer, the outer surface of which can be coated with polyimide. In other embodiments, the cleanroom foam composite film may also include electromagnetic shielding layers, light-shielding layers, release films, or protective films. In still other embodiments, the connecting layer SCF can also be ordinary double-sided tape or an adhesive layer coated on the surfaces of the first back film BF1 and the second back film BF2. The thickness of the connecting layer SCF can be set according to actual needs. In some implementations, the thickness of the connecting layer SCF can be between 10 micrometers and 100 micrometers.

[0055] The support member 10 is disposed between the connecting layer SCF and the second back film BF2. Specifically, the support member 10 is located on the side of the connecting layer SCF that is away from the first back film BF1, and on the side of the second back film BF2 that is away from the bending area PNL3.

[0056] The support member 10 includes a first support portion 1, a second support portion 2, and a connecting portion 3. The first support portion 1 abuts against the connecting layer SCF, that is, the first support portion 1 indirectly contacts the first back film BF1 and the second back film BF2 through the connecting layer SCF, thereby transferring the supporting force to the display area PNL1 of the display panel PNL. The second support portion 2 abuts against the second back film BF2, that is, the second support portion 2 directly contacts the surface of the second back film BF2, thereby transferring the supporting force to the area where the bonding area PNL2 is located. The connecting portion 3 connects the first support portion 1 and the second support portion 2, and can change the distance between the first support portion 1 and the second support portion 2 along the thickness direction of the display panel PNL.

[0057] The way the connecting part 3 changes the distance between the first support part 1 and the second support part 2 along the thickness direction of the display panel PNL can be flexibly set.

[0058] In some embodiments, the connecting part 3 can adopt an elastic structure, and the distance between the first support part 1 and the second support part 2 can dynamically change with the change of external load. When the external gap increases, the connecting part 3 elastically extends, causing the second support part 2 to move away from the first support part 1, thereby compensating for the increased gap; when the external gap decreases, the connecting part 3 elastically compresses, causing the second support part 2 to move closer to the first support part 1, avoiding excessive pre-stress on the display panel PNL. This dynamic adjustment method allows the support member 10 to adapt in real time to gap fluctuations caused by factors such as thermal expansion and contraction and vibration during the use of the display device 1000, thereby effectively preventing support failure or excessive pressure on the display panel PNL.

[0059] In other embodiments, the connecting portion 3 can adopt a plastically deformable structure. Before the support member 10 is installed onto the display module 100, an external force is applied to the connecting portion 3 to pre-adjust the distance between the first support portion 1 and the second support portion 2 according to the support height required for the specific application scenario. This ensures that the support member 10 can precisely fill the gap between the display module 100 and the external components after assembly. This pre-adjustment method allows the same support member 10 structure to adapt to display devices 1000 of different models and different assembly tolerances, eliminating the need to customize the size of the support member 10 for each case.

[0060] In some other embodiments, the connecting part 3 can simultaneously have both elastic adjustment and pre-adjustment functions. That is, the connecting part 3 can undergo reversible elastic deformation within a certain range to adapt to dynamic working conditions, and can also set the foundation support height through irreversible plastic deformation during initial assembly.

[0061] According to the display module 100 provided in this application embodiment, the connecting part 3 can change the thickness direction distance between the first support part 1 and the second support part 2, so that the support member 10 as a whole can be adaptively adjusted according to the actual assembly gap and dynamic working conditions. The display module 100 can effectively compensate for the gap fluctuation between the display module 100 and external components caused by dynamic factors such as thermal expansion and contraction and vibration, avoid support failure or excessive pressure on the display panel PNL. At the same time, the same support member 10 structure can be applied to various display devices 1000 with different models and tolerance ranges, improving the product's versatility and design flexibility. Furthermore, through the deformation or buffering effect of the connecting part 3, it can absorb some impact energy under drop or impact conditions, reducing the risk of display panel PNL breakage.

[0062] Please see Figure 1 and Figure 2 According to some embodiments of this application, the connecting part 3 can be connected between the first support part 1 and the second support part 2, and at least a portion of the connecting part 3 can elastically deform along the thickness direction of the display panel PNL.

[0063] The connecting part 3 is used to connect the first support part 1 and the second support part 2, and to transmit the force on the first support part 1 and the force on the second support part 2 between them. At least a portion of the connecting part 3 can elastically deform along the thickness direction of the display panel PNL, so that the thickness direction distance between the first support part 1 and the second support part 2 can dynamically change with the change of external load.

[0064] When the external load increases, the connecting part 3 undergoes elastic compression, and the distance between the first support part 1 and the second support part 2 decreases; when the external load decreases, the connecting part 3 elastically recovers, and the distance between the first support part 1 and the second support part 2 increases. Through this elastic deformation, the support member 10 can automatically adapt when the assembly gap between the display module 100 and the external components changes, maintaining a stable supporting force, avoiding support failure due to increased gap, and also avoiding excessive pre-stress on the display panel PNL due to decreased gap.

[0065] In some embodiments, the connecting part 3 may be made entirely of an elastic material, such as silicone rubber, polyurethane elastomer, thermoplastic elastomer, etc., and the entire connecting part 3 may undergo elastic deformation in the thickness direction.

[0066] In other embodiments, the connecting portion 3 may include a rigid segment and an elastic segment, with the elastic segment located between the rigid segments or between the rigid segments and the first support portion 1 or the second support portion 2. The elastic segment is made of an elastic material or constructed as an elastic structure, thereby achieving local elastic deformation of the connecting portion 3.

[0067] In some other embodiments, the connecting part 3 may be made of metal or rigid plastic, but its structure is configured to be elastically deformable in the thickness direction. For example, the connecting part 3 has a bent structure, a wave structure or a spiral structure, which provides elasticity through structural deformation.

[0068] The connecting part 3, the first support part 1, and the second support part 2 can be an integrally formed structure, or they can be separate structures that are fixedly connected by means of bonding, welding, snap-fitting, etc.

[0069] The elastic deformation characteristics of the connecting part 3 enable the support member 10 to dynamically compensate for the assembly gap between the display module 100 and the external components in real time, effectively improving the structural stability and display quality of the display module 100 under dynamic working conditions. At the same time, the elastic deformation of the connecting part 3 itself can absorb and dissipate some of the impact energy, reducing the peak impact force transmitted to the display panel PNL when the display device 1000 is dropped or subjected to accidental impact, thereby protecting the display panel PNL from damage.

[0070] Please see Figure 1 and Figure 2According to some embodiments of this application, the connecting portion 3 may include a first connecting portion 31, a second connecting portion 32, and an elastic portion 33. The first connecting portion 31 may be connected to the first support portion 1. The second connecting portion 32 may be connected to the second support portion 2. One end of the elastic portion 33 is connected to the first connecting portion 31, and the other end is connected to the second connecting portion 32. The elastic portion 33 may elastically extend and retract along the thickness direction of the display panel PNL.

[0071] The first connecting portion 31 is used to structurally associate the connecting portion 3 with the first support portion 1, so that the elastic force generated by the elastic portion 33 can be transmitted to the first support portion 1 through the first connecting portion 31, and then to the display area PNL1 of the display panel PNL via the connecting layer SCF. The second connecting portion 32 is used to structurally associate the connecting portion 3 with the second support portion 2, so that the elastic force generated by the elastic portion 33 can be transmitted to the second support portion 2 through the second connecting portion 32, and then to the bonding area PNL2 of the display panel PNL via the second back film BF2.

[0072] The first connecting part 31 and the second connecting part 32 can be rigid structures or structures with a certain degree of elasticity, as long as they can effectively transmit the force of the elastic part 33.

[0073] In some embodiments, the first connecting part 31 and the first supporting part 1, and the second connecting part 32 and the second supporting part 2, can be fixedly connected by means of bonding, welding, snap-fitting, threaded connection, etc.

[0074] In other embodiments, the first connecting part 31 and the first supporting part 1 are integrally formed, and the second connecting part 32 and the second supporting part 2 are integrally formed, thereby simplifying the manufacturing process and improving the connection strength.

[0075] The elastic part 33 is the core functional component in the connecting part 3 that realizes elastic deformation. When the assembly gap between the display module 100 and the external component changes, the elastic part 33 extends or compresses accordingly to automatically adapt to gap fluctuations. Specifically, when the external gap increases, the elastic part 33 elastically extends, pushing the second support part 2 to move away from the first support part 1, so that the second support part 2 remains in contact with the external component, thereby maintaining the support effect; when the external gap decreases, the elastic part 33 is compressed, and the second support part 2 moves towards the first support part 1, avoiding the second support part 2 from generating excessive pushing force on the external component, thereby preventing this force from being transmitted to the display panel PNL through the connecting layer SCF, causing the display area PNL1 or the bonding area PNL2 to bear excessive pre-pressure.

[0076] Through the elastic expansion and contraction of the elastic part 33, the support member 10 can always maintain real-time tracking and compensation of the gap between the display module 100 and the external components under dynamic working conditions, effectively avoiding support failure or damage to the display panel PNL caused by gap fluctuation.

[0077] In some embodiments, the elastic part 33 can be a spring, with one end of the spring fixedly connected to the first connecting part 31 and the other end fixedly connected to the second connecting part 32, and elastic expansion and contraction are achieved by the compression and elongation of the helical spring.

[0078] In other embodiments, the elastic part 33 can be a spring sheet, which can be arc-shaped, wavy, or S-shaped, and elastic expansion and contraction in the thickness direction can be achieved by bending and deforming the spring sheet.

[0079] In some other embodiments, the elastic part 33 can be an elastic column or an elastic block made of an elastic material, such as silicone rubber, polyurethane elastomer, thermoplastic elastomer or foam material, which achieves elastic expansion and contraction through the compression deformation of the material itself.

[0080] The elastic part 33 can be provided one or more times. In some embodiments, the connecting part 3 has two elastic parts 33, which can be symmetrically arranged between the first connecting part 31 and the second connecting part 32 to improve the stability of the support. In other embodiments, the connecting part 3 has three, four or more elastic parts 33, which can be evenly distributed along the circumference of the first connecting part 31 and the second connecting part 32 to make the distribution of the support force more uniform.

[0081] Please see Figure 1 and Figure 2 According to some embodiments of this application, the first connecting portion 31 and the second connecting portion 32 can be guided and fitted along the thickness direction of the display panel PNL.

[0082] The guiding engagement between the first connecting portion 31 and the second connecting portion 32 provides guiding constraints on the relative movement of the first connecting portion 31 and the second connecting portion 32 in the thickness direction of the display panel PNL. This ensures that during the expansion and contraction of the elastic portion 33, the first connecting portion 31 and the second connecting portion 32 can stably move closer or further apart relative to each other along the thickness direction without shifting or tilting in a direction perpendicular to the thickness direction. Through the guiding engagement, the overall structural stability of the support member 10 is enhanced, and the elastic expansion and contraction of the elastic portion 33 can be restricted to the expected thickness direction, avoiding changes in the direction of the supporting force or local stress concentration caused by skewness or misalignment.

[0083] In some embodiments, the first connecting part 31 is provided with a guide groove that extends along the thickness direction of the display panel PNL, and the second connecting part 32 is provided with a guide protrusion that extends into the guide groove and can slide along the guide groove, thereby realizing the guiding engagement between the first connecting part 31 and the second connecting part 32.

[0084] In some embodiments, one of the first connecting portion 31 and the second connecting portion 32 is provided with a guide hole, and the other is provided with a guide post. The guide post passes through the guide hole and can slide relative to the first portion along the thickness direction. The cross-sectional shape of the guide groove can be rectangular, trapezoidal, circular, or dovetail-shaped, etc., and the shape of the guide protrusion matches the guide groove. A clearance fit can be used between the guide groove and the guide protrusion to ensure smooth relative sliding; alternatively, an interference fit can be used to provide a certain frictional damping, making the dynamic response of the support member 10 more stable.

[0085] In some embodiments, the guide fit may also include a limiting structure for limiting the maximum relative displacement between the first connecting portion 31 and the second connecting portion 32, so as to prevent the elastic portion 33 from being damaged due to excessive stretching or excessive compression.

[0086] The guiding fit between the first connecting part 31 and the second connecting part 32 works in conjunction with the elastic part 33. When the elastic part 33 elastically expands and contracts along the thickness direction of the display panel PNL, the first connecting part 31 and the second connecting part 32 move relative to each other under the constraint of the guiding fit, ensuring that the elastic force generated by the elastic part 33 is always transmitted along the thickness direction, thus ensuring the consistency of the direction of the supporting force. At the same time, the guiding fit can also withstand lateral loads when the support member 10 is subjected to lateral forces other than those in the thickness direction, through the abutment between the guide groove and the guide protrusion, preventing the elastic part 33 from bending or buckling laterally, thereby improving the structural reliability of the support member 10 under complex stress conditions.

[0087] Please see Figure 1 and Figure 2 According to some embodiments of this application, the first connecting portion 31 may be provided with a first mounting groove 311 on the side facing the second connecting portion 32, and the second connecting portion 32 may be provided with a second mounting groove 321 on the side facing the first connecting portion 31; one end of the elastic portion 33 is connected to the bottom of the first mounting groove 311, and the other end is connected to the bottom of the second mounting groove 321; wherein, at least a portion of the first connecting portion 31 extends into the second mounting groove 321, or at least a portion of the second connecting portion 32 extends into the first mounting groove 311.

[0088] A first mounting groove 311 is provided on the surface of the first connecting portion 31 facing the second connecting portion 32, and a second mounting groove 321 is provided on the surface of the second connecting portion 32 facing the first connecting portion 31. The first mounting groove 311 is used to accommodate at least a portion of the structure of the elastic portion 33 and provides a mounting and positioning base for one end of the elastic portion 33; the second mounting groove 321 is used to accommodate at least a portion of the structure of the elastic portion 33 and provides a mounting and positioning base for the other end of the elastic portion 33. The arrangement of the first mounting groove 311 and the second mounting groove 321 allows the two ends of the elastic portion 33 to be effectively limited during the expansion and contraction process, preventing the elastic portion 33 from laterally buckling during compression or shifting during extension.

[0089] One end of the elastic part 33 can be fixed to the bottom of the first assembly groove 311 by means of bonding, snapping, welding or integral molding, and the other end can be fixed to the bottom of the second assembly groove 321 by the same or different means.

[0090] The walls of the first assembly groove 311 and the second assembly groove 321 simultaneously serve as guide surfaces for the guiding fit. At least a portion of the first connecting portion 31 extends into the second assembly groove 321, or at least a portion of the second connecting portion 32 extends into the first assembly groove 311, thereby forming a nested structure. This nested structure restricts the relative movement between the first connecting portion 31 and the second connecting portion 32 to the thickness direction, achieving a guiding fit.

[0091] Specifically, when at least a portion of the first connecting part 31 extends into the second mounting groove 321, a sliding fit is formed between the outer wall of the portion of the first connecting part 31 extending into the second mounting groove 321 and the groove wall of the second mounting groove 321. When the first connecting part 31 and the second connecting part 32 move relative to each other along the thickness direction under the action of the elastic part 33, the fit between the outer wall and the groove wall plays a guiding and constraining role. When at least a portion of the second connecting part 32 extends into the first mounting groove 311, a sliding fit is formed between the outer wall of the portion of the second connecting part 32 extending into the first mounting groove 311 and the groove wall of the first mounting groove 311, similarly achieving guiding and constraining. Through this nested guiding structure, the support member 10 will not experience radial displacement when it expands and contracts in the thickness direction, and the transmission direction of the supporting force remains consistent.

[0092] In some embodiments, the first assembly groove 311 and the second assembly groove 321 are both cylindrical grooves, and the elastic part 33 is a cylindrical helical spring or a cylindrical elastic column, with both ends of the elastic part 33 respectively accommodated in the first assembly groove 311 and the second assembly groove 321.

[0093] In other embodiments, the first assembly groove 311 and the second assembly groove 321 are both rectangular grooves, and the elastic part 33 is a plate-shaped spring or an elastic column with a rectangular cross-section.

[0094] The nested structure allows the first connecting portion 31 and the second connecting portion 32 to overlap in the thickness direction. This overlap not only provides a guiding function but also significantly reduces the dimensions of the support member 10 outside the thickness direction, making the overall structure of the support member 10 more compact. This facilitates the support function within the limited installation space between the display module 100 and external components. Simultaneously, at least a portion of the first connecting portion 31 extends into the second mounting groove 321, or at least a portion of the second connecting portion 32 extends into the first mounting groove 311. This ensures that the overall height of the support member 10 remains within a relatively compact range when the distance between the first support portion 1 and the second support portion 2 changes. It prevents excessive lateral dimensional changes due to the expansion and contraction of the connecting portion 3 in the thickness direction, which is beneficial for the spatial layout of the support member 10 within the display device 1000.

[0095] Please see Figure 3 and Figure 4 According to some embodiments of this application, the support member 10 may further include a first liner 4 and a second liner 5. The first liner 4 may be connected to the side of the first support 1 facing the second support 2, and the second liner 5 may be connected to the side of the second support 2 facing the first support 1. The first connecting part 31 may be installed on the first liner 4, and the second connecting part 32 may be installed on the second liner 5.

[0096] The first backing plate 4 is disposed on the surface of the first support portion 1 facing the second support portion 2, serving to provide an installation base for the first connecting portion 31 and uniformly transmit the force on the first connecting portion 31 to the first support portion 1. The arrangement of the first backing plate 4 significantly increases the contact area between the first support portion 1 and the first connecting portion 31. When the first support portion 1 is made of a soft material, if the first connecting portion 31 directly contacts the first support portion 1, the first connecting portion 31 may partially sink into the first support portion 1 under stress, causing local indentations or damage to the first support portion 1. This indentation may even be transmitted through the connecting layer SCF to the backlight side of the display panel PNL, adversely affecting the display panel PNL. By providing the first backing plate 4 between the first support portion 1 and the first connecting portion 31, the installation force of the first connecting portion 31 and the supporting force transmitted to the first support portion 1 are both dispersed through the first backing plate 4, avoiding local stress concentration and protecting the structural integrity of the first support portion 1.

[0097] The second liner 5 is disposed on the surface of the second support portion 2 facing the first support portion 1, serving to provide an installation base for the second connecting portion 32 and to evenly transmit the force on the second connecting portion 32 to the second support portion 2. The second liner 5 also increases the contact area between the second support portion 2 and the second connecting portion 32. When the second support portion 2 is made of a soft material, the second connecting portion 32 will not directly and locally sink into the second support portion 2; instead, the force is evenly distributed over a larger area of ​​the second support portion 2 through the second liner 5, thereby avoiding localized indentations or damage to the second support portion 2 and preventing the potential impact of such damage on the second backsheet BF2 and the bonding area PNL2.

[0098] The first liner 4 and the second liner 5 can be made of rigid materials. In some embodiments, the first liner 4 and the second liner 5 can be made of metallic materials, such as stainless steel sheets, aluminum sheets, or copper sheets. Metallic materials have high hardness and good thermal conductivity, providing structural support while also aiding in heat dissipation. In other embodiments, the first liner 4 and the second liner 5 can be made of rigid plastics or composite materials, such as polycarbonate sheets, polyimide sheets, or glass fiber reinforced epoxy resin sheets. These materials have high hardness and low density, which helps to reduce the overall weight of the support member 10.

[0099] In some embodiments, the first liner 4 is adhered to the surface of the first support portion 1 by adhesive, and the second liner 5 is adhered to the surface of the second support portion 2 by adhesive. In other embodiments, the first liner 4 and the first support portion 1 are fixedly connected by double-sided tape, and the second liner 5 and the second support portion 2 are fixedly connected by double-sided tape. In still other embodiments, the first liner 4 can be embedded inside the first support portion 1 or integrally formed with the first support portion 1 by injection molding, and the second liner 5 can be embedded inside the second support portion 2 or integrally formed with the second support portion 2 by injection molding.

[0100] In some embodiments, the first connecting part 31 and the first liner 4 are fixed together by adhesive bonding, and the second connecting part 32 and the second liner 5 are fixed together by adhesive bonding. In other embodiments, the first connecting part 31 and the first liner 4 are connected by threaded connection or snap-fit ​​connection, and the second connecting part 32 and the second liner 5 are connected by threaded connection or snap-fit ​​connection, to facilitate the disassembly, assembly, and maintenance of the support member 10. In still other embodiments, the first connecting part 31 and the first liner 4 are integrally formed, and the second connecting part 32 and the second liner 5 are integrally formed, to simplify the manufacturing process and improve the reliability of the connection.

[0101] With the first liner 4 and the second liner 5, the support member 10 can evenly distribute the supporting force generated by the connecting part 3 and the elastic part 33 to the first support part 1 and the second support part 2, avoiding problems such as indentation or damage to the support part or uneven pressure on the display panel PNL caused by local stress concentration. At the same time, the first liner 4 and the second liner 5 also provide a more stable mounting base for the first connecting part 31 and the second connecting part 32, making the connection between the connecting part 3 and the support part more reliable, and improving the overall structural strength and long-term reliability of the support member 10.

[0102] Please see Figure 2 , Figure 3 and Figure 4 According to some embodiments of this application, the elastic part 33 may include a spring.

[0103] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 According to some embodiments of this application, the support member 10 includes a plurality of connecting portions 3, which are evenly distributed along the extension direction of the plane on which the support member 10 is located.

[0104] The connecting part 3 is used to connect the first support part 1 and the second support part 2, and changes the thickness direction distance between the first support part 1 and the second support part 2 through the elastic expansion and contraction of its elastic part 33. By providing multiple connecting parts 3, the support member 10 can provide support force and elastic adjustment capability at multiple positions simultaneously, thereby distributing the support force to multiple areas of the first support part 1 and the second support part 2, avoiding the support force being concentrated at a single position, which would cause excessive local pressure on the display panel PNL or local deformation of the support part.

[0105] Multiple connecting parts 3 are evenly distributed along the extension direction of the plane where the support member 10 is located, so that the external load borne by the support member 10 can be evenly distributed by each connecting part 3, ensuring that the supporting force on each area of ​​the first support part 1 and the second support part 2 is roughly the same, thereby improving the overall support stability and reliability of the support member 10.

[0106] The plane containing the support member 10 refers to the plane on which the support member 10 as a whole is located. This plane is approximately parallel to the plane containing the display area PNL1 of the display panel PNL, that is, a plane perpendicular to the thickness direction of the display panel PNL. "Uniformly distributed along the extension direction of the plane containing the support member 10" means that the multiple connecting parts 3 are arranged at approximately equal intervals within a plane perpendicular to the thickness direction. This uniform distribution ensures that the interval between any two adjacent connecting parts 3 is basically consistent, thereby ensuring that the supporting force is evenly covered across the entire plane of the support member 10, avoiding situations where the local support is too strong or insufficient.

[0107] It is understood that the multiple connecting parts 3 can work independently, and the elastic part 33 of each connecting part 3 can independently undergo elastic expansion and contraction. When the display module 100 is subjected to an external load, if the load only acts on a local area of ​​the support member 10, the connecting part 3 corresponding to that area will independently undergo elastic deformation to absorb and buffer the local load, while the connecting parts 3 in other areas will maintain their original state or respond independently according to their respective loads. This independent expansion and contraction characteristic allows the support member 10 to adapt to non-uniformly distributed gap changes or impact loads. For example, when the display device 1000 is dropped, the impact force may first act on a certain end or corner of the support member 10. The connecting part 3 at that position will quickly compress and absorb the impact energy, while the connecting parts 3 at other positions will respond accordingly according to the actual force conditions. This effectively avoids the impact force being concentrated and transmitted to a single area of ​​the display panel PNL, significantly enhancing the impact resistance and adaptability of the support member 10 to different stress conditions.

[0108] The natural lengths of the multiple connecting parts 3 can be the same or different.

[0109] In some embodiments, the natural lengths of each connecting part 3 are the same, so that the distance between the first support part 1 and the second support part 2 is consistent in the natural state of the support member 10, which is suitable for application scenarios where the gap between the display module 100 and the external components is uniform.

[0110] In other embodiments, the natural lengths of the connecting parts 3 are not entirely the same; some connecting parts 3 have longer natural lengths, while others have shorter natural lengths. This design allows the support member 10 to adapt to the surfaces of external components with different thicknesses or varying heights. For example, when the surface of an external component has steps, unevenness, or an inclined structure, the connecting parts 3 at different locations can be pre-set with different natural lengths to match these structural differences. This ensures that after the support member 10 is installed, each connecting part 3 is in a suitable compressed or elongated state. Consequently, it is not necessary to design support members 10 of different specifications for different locations during the overall assembly, further improving the versatility and design flexibility of the support member 10.

[0111] The stiffness of the elastic portion 33 of each connecting part 3 can be the same or different. In some embodiments, the stiffness of the elastic portion 33 of the connecting part 3 located in the edge region of the support member 10 can be greater than that of the elastic portion 33 of the connecting part 3 located in the central region, so as to better resist stress concentration in the edge region. In other embodiments, the stiffness of the elastic portion 33 of each connecting part 3 is the same, so as to simplify design and manufacturing.

[0112] Multiple connecting parts 3 can be arranged in an array along the length and width of the support member 10, such as in two rows and two columns, two rows and three columns, or three rows and three columns, to provide a uniform distribution of supporting force on the large area of ​​the support member 10. The specific number of connecting parts 3 needs to be determined comprehensively based on factors such as the overall size of the support member 10, the area of ​​the first support part 1 and the second support part 2, the required supporting force, and the installation space.

[0113] It is understood that each connecting part 3 includes a first connecting part 31, a second connecting part 32, and an elastic part 33. When multiple connecting parts 3 are evenly distributed along the extension direction of the plane where the support member 10 is located, the first connecting part 31 of each connecting part 3 is connected to the first support part 1 (for example, indirectly connected through the first liner 4), the second connecting part 32 of each connecting part 3 is connected to the second support part 2 (for example, indirectly connected through the second liner 5), and the elastic part 33 of each connecting part 3 is connected between the corresponding first connecting part 31 and second connecting part 32.

[0114] According to the display module 100 provided in the embodiments of this application, by providing an elastic part 33 in the connecting part 3, a stretchable structure with elastic recovery force is introduced as a restraint means, so that the support member 10 can generate a reverse force when the assembly gap changes, achieving the effect of real-time and automatic adjustment of its own thickness and contact pressure. This solves the dynamic adaptability problem of traditional support members 10 either failing due to increased gap or being pressured on the screen due to decreased gap under conditions of temperature fluctuation and assembly tolerance. Furthermore, a micro-stretching mechanism with buffering energy absorption characteristics is constructed as a restraint means, so that the support member 10 can extend the action time through controllable deformation when subjected to impact load, achieving the effect of efficiently dissipating impact energy and reducing peak acceleration. This solves the structural reliability problem that rigid support members 10 are prone to damage to the display module 100 or connectors in the event of accidental drops or frequent vibrations.

[0115] Please see Figure 5 , Figure 6 , Figure 7 According to some embodiments of this application, the connecting part 3 may have a gap, and at least part of the gap is located between the first support part 1 and the second support part 2.

[0116] The connecting portion 3 is connected between the first support portion 1 and the second support portion 2, and at least part of it is elastically deformable along the thickness direction of the display panel PNL. A gap is provided in the connecting portion 3, which provides space for the connecting portion 3 to be compressed in the thickness direction.

[0117] When an external load acts on the support member 10 along the thickness direction, the connecting part 3 is subjected to pressure, the volume of the gap decreases, and the connecting part 3 as a whole is compressed in the thickness direction, reducing the distance between the first support part 1 and the second support part 2. When the external load decreases, the connecting part 3 elastically recovers, the volume of the gap increases, and the distance between the first support part 1 and the second support part 2 increases. The elastic expansion and contraction of the connecting part 3 is achieved by changing the volume of the gap, thereby enabling the support member 10 to adapt to the dynamic changes in the assembly gap between the display module 100 and the external components.

[0118] The fact that at least part of the gap is located between the first support part 1 and the second support part 2 means that at least part of the gap is located between the first support part 1 and the second support part 2 in the thickness direction, thereby ensuring that the compression and expansion of the gap can be directly converted into the change of distance between the first support part 1 and the second support part 2, making the thickness adjustment response of the support member 10 more direct and efficient.

[0119] The implementation of the gap can be flexibly designed. In some embodiments, the connecting part 3 is made of an elastic material and has a closed cavity inside, filled with gas, such as air or an inert gas. When the connecting part 3 is subjected to pressure, the wall of the cavity undergoes elastic deformation, the cavity volume decreases, and the gas is compressed, producing a cushioning effect similar to a gas spring; when the pressure is released, the cavity wall returns to its initial shape under the combined action of its own elasticity and the internal gas pressure. In other embodiments, the connecting part 3 is made of a porous elastic material, such as foamed rubber, foamed polyurethane, or foamed silicone. The porous elastic material has a large number of interconnected or closed pores inside, which constitute a gap. When the connecting part 3 is subjected to pressure, the pore walls deform, the pore volume decreases, and the connecting part 3 as a whole is compressed; when the pressure is released, the pore walls return to their original shape due to the elasticity of the material itself, and the connecting part 3 expands back to its original shape. In some other embodiments, the connecting part 3 is provided with an independent elastic airbag, which is embedded inside the connecting part 3 and filled with gas. The elastic expansion and contraction of the connecting part 3 is achieved by compressing and expanding the airbag. The material of the connecting part 3 can be silicone rubber, polyurethane elastomer, thermoplastic elastomer, natural rubber, or other materials with good elasticity and durability.

[0120] The design of the connecting part 3 with a gap utilizes the volume change of the gap to achieve elastic expansion and contraction, providing excellent buffering and vibration absorption performance. When the display device 1000 is dropped or subjected to an accidental impact, the external impact force is transmitted to the connecting part 3 through the second support part 2. The gap within the connecting part 3 is rapidly compressed, and the impact energy is converted into the heat energy of gas compression within the gap and the deformation energy of the connecting part 3 material. This effectively absorbs and dissipates the impact energy, significantly reducing the peak impact force transmitted to the display panel PNL. Simultaneously, due to the damping effect generated by the gas within the gap during compression, the connecting part 3 exhibits good motion stability during expansion and contraction, avoiding secondary impacts caused by elastic vibration.

[0121] Please see Figure 5 According to some embodiments of this application, the connecting part 3 can be hollow, and the gap can be a closed cavity 34 inside the connecting part 3.

[0122] The enclosed cavity 34 is the gap described in the aforementioned embodiment. The enclosed cavity 34 is filled with a gas, such as air, nitrogen, or other chemically stable gases. The connecting part 3 achieves elastic expansion and contraction along the thickness direction of the display panel PNL through the compressibility of the gas inside the enclosed cavity 34 and the elastic deformation of the connecting part 3's own wall surface.

[0123] When an external load is applied to the support member 10, the connecting part 3 is subjected to pressure, the volume of the closed cavity 34 decreases, the internal gas is compressed, and the wall surface of the connecting part 3 undergoes elastic deformation. When the external load decreases, the gas in the closed cavity 34 expands, pushing the wall surface of the connecting part 3 back to its initial shape, and the connecting part 3 rebounds as a whole. Through this airbag-like working principle, the connecting part 3 can undergo reversible elastic deformation in the thickness direction, thereby achieving dynamic adaptation to the assembly gap between the display module 100 and the external components.

[0124] In some embodiments, the connecting portion 3 is entirely flat, extending in a plane perpendicular to the thickness direction of the display panel PNL, and its area is approximately equal to that of the first support portion 1 and the second support portion 2. In other words, the entire space between the first support portion 1 and the second support portion 2 is occupied by this single connecting portion 3. The connecting portion 3 is a single, integral structure, and the enclosed cavity 34 formed inside it is also flat, extending over a large area between the first support portion 1 and the second support portion 2. This large-area flat airbag structure provides a larger gas compression space and a larger deformation stroke, enabling the support member 10 to adapt to a wider range of gap changes and providing a more adequate cushioning effect under impact conditions.

[0125] In some embodiments, the connecting part 3 is integrally molded from an elastic material, such as silicone rubber, polyurethane elastomer, thermoplastic elastomer, or natural rubber, forming an internal closed cavity 34 through blow molding, injection molding, or compression molding. The integral molding method ensures good sealing of the closed cavity 34, preventing gas leakage and support failure. In other embodiments, the connecting part 3 is formed by sealing two elastic films along their edges, forming a closed cavity 34 between the two films. The edge sealing can be achieved through heat sealing, ultrasonic sealing, or adhesive sealing.

[0126] The wall thickness of the connecting part 3 and the volume of the enclosed cavity 34 can be set according to the required support stiffness and buffering performance. When the wall thickness is thinner, the connecting part 3 has better elasticity and is more sensitive to small loads, making it suitable for applications requiring high-sensitivity dynamic compensation; when the wall thickness is thicker, the connecting part 3 has greater support stiffness and can withstand greater loads, making it suitable for applications requiring greater support force.

[0127] The gas pressure within the enclosed cavity 34 can be one standard atmosphere, or it can be set higher or lower than the standard atmosphere depending on actual needs. In some embodiments, the gas pressure filling the enclosed cavity 34 is higher than the ambient atmospheric pressure. This pre-pressurization design gives the connection part 3 higher initial support stiffness, enabling it to better resist static loads. In other embodiments, the gas pressure filling the enclosed cavity 34 is lower than the ambient atmospheric pressure, making the connection part 3 more sensitive to pressure changes and giving it lower initial stiffness.

[0128] The upper and lower surfaces of the connecting portion 3 are connected to the first support portion 1 and the second support portion 2, respectively. In some embodiments, the upper surface of the connecting portion 3 is fixedly connected to the surface of the first support portion 1 facing the second support portion 2 by an adhesive, and the lower surface of the connecting portion 3 is fixedly connected to the surface of the second support portion 2 facing the first support portion 1 by an adhesive. In other embodiments, the first support portion 1 and the second support portion 2 are integrally formed with the connecting portion 3, for example, by providing bonding layers compatible with the materials of the first support portion 1 and the second support portion 2 on the upper and lower surfaces of the connecting portion 3, and achieving integral connection through co-vulcanization or co-injection molding. In still other embodiments, the connecting portion 3 is fixed to the first support portion 1 and the second support portion 2 by double-sided tape or a hot melt adhesive layer.

[0129] Please see Figure 5 According to some embodiments of this application, the connecting part 3 may include an airtight layer and a reinforcing layer. The airtight layer has a closed cavity 34 inside. The reinforcing layer can wrap around the airtight layer and the structural strength of the reinforcing layer is greater than that of the airtight layer. The first support part 1 and the second support part 2 are disposed on both sides of the reinforcing layer in the thickness direction of the display panel PNL.

[0130] The airtight layer is the inner structure of the connecting part 3, and a closed cavity 34 is formed inside it. The closed cavity 34 is used to contain gas, and the elastic expansion and contraction of the connecting part 3 along the thickness direction of the display panel PNL is achieved by changing the volume of the closed cavity 34. The airtight layer has good airtightness and can seal the gas in the closed cavity 34 for a long time, preventing gas leakage from causing support failure.

[0131] The airtight layer can be made of an elastic material with excellent airtightness. In some embodiments, the airtight layer is made of silicone, which has excellent airtightness, a wide temperature range, and good chemical stability, ensuring that the support 10 has no risk of leakage during long-term use. In other embodiments, the airtight layer is made of butyl rubber, fluororubber, or polyurethane elastomer, which also have good airtightness and elasticity. The wall thickness of the airtight layer can be set according to the required sealing performance and elastic deformation capacity.

[0132] A reinforcing layer surrounds the airtight layer, providing structural reinforcement and protection. The reinforcing layer has a higher structural strength than the airtight layer, thus restraining excessive deformation of the airtight layer under external pressure and preventing localized over-expansion or rupture of the sealed cavity 34 due to sudden increases in internal air pressure. Simultaneously, the reinforcing layer enhances the tear resistance of the airtight layer. When the support member 10 is subjected to non-uniform loads or localized compression from sharp objects, the reinforcing layer effectively resists tearing and puncture, ensuring the structural integrity and airtightness of the airtight layer. The inclusion of the reinforcing layer allows the airtight layer to achieve higher structural reliability and durability while maintaining excellent elastic deformation capacity and airtightness.

[0133] In some embodiments, the reinforcing layer can be a reinforcing film layer wrapped around the outer surface of the airtight layer. This reinforcing film layer can be made of materials with high mechanical strength, such as polyethylene terephthalate film, polyimide film, or polyethylene naphthalate film. In other embodiments, the reinforcing layer can be a fiber reinforcing layer, comprising woven fibers or nonwoven fabrics, such as nylon fiber fabric, polyester fiber fabric, or aramid fiber fabric. The fiber fabric is bonded to the outer surface of the airtight layer by adhesives or hot pressing. In still other embodiments, the reinforcing layer can be a reinforcing layer formed through material modification. Specifically, during the molding process of the airtight layer, the outer surface area is reinforced with a higher structural strength than the internal areas by increasing the crosslinking density, adding reinforcing fillers, or undergoing surface hardening treatment.

[0134] In embodiments where the reinforcing layer is an independent film layer or fiber cloth layer, the reinforcing layer can be welded and sealed to the outer surface of the airtight layer through a ring-shaped heat sealing process. The ring-shaped heat sealing forms a strong interfacial bond between the reinforcing layer and the airtight layer, while ensuring that the sealed cavity 34 maintains good airtightness. Specifically, the airtight layer is made of silicone material, and the reinforcing layer is made of modified silicone material. The modified silicone material has higher structural strength and tear toughness than the silicone material used in the airtight layer by adding reinforcing fillers or adjusting the crosslinking system. The two are integrated through co-vulcanization or ring-shaped heat sealing.

[0135] The structural strength of the reinforcing layer is greater than that of the airtight layer. Specifically, at least one of the tensile strength, tear strength, puncture strength, or hardness of the reinforcing layer is higher than the corresponding performance parameter of the airtight layer.

[0136] The first support portion 1 and the second support portion 2 can be made of soft materials to provide a flexible contact interface between the support member 10 and the display panel PNL and external components. In some embodiments, the first support portion 1 and the second support portion 2 are made of soft silicone pads. Soft silicone pads have good flexibility and biocompatibility, and can form a good contact fit with the surfaces of the display panel PNL and external components, avoiding scratches to the display device or external components by hard structures, while further optimizing contact compatibility. The soft silicone pads can be made of medical-grade silicone material with moderate softness, balancing cushioning and protection.

[0137] The airtight layer, the reinforcing layer, the first support part 1, and the second support part 2 together constitute the overall structure of the support member 10. When an external load is applied to the support member 10, the load is first transferred to the reinforcing layer via the second support part 2. The reinforcing layer then distributes the load and transfers it to the airtight layer. The closed cavity 34 within the airtight layer is compressed to absorb and buffer the load. When the external load is released, the airtight layer elastically recovers, and the reinforcing layer recovers accordingly. By wrapping and reinforcing the airtight layer, the reinforcing layer ensures that the airtight layer maintains good structural stability during repeated compression and recovery, avoiding a decrease in airtightness or structural damage due to excessive local deformation. At the same time, the viscoelastic properties of the silicone material in the airtight layer and the damping effect of the gas within the closed cavity 34 work synergistically to significantly attenuate high-frequency vibrations and effectively eliminate abnormal noise from the entire device. The first support part 1 and the second support part 2 are located on both sides of the reinforcing layer, providing a flexible contact interface between the support member 10 and the display panel PNL and external components, ensuring that the support member 10 provides stable support without causing secondary damage to the display panel PNL. The dual-layer composite structure of the airtight layer and the reinforcing layer, along with the soft contact layer structure of the first support part 1 and the second support part 2, together constitute the support member 10, which has excellent airtightness, structural strength, tear resistance and contact compatibility. It can meet the stringent requirements of the display module 100 for the support member 10 in terms of long-term reliability, impact resistance and device protection.

[0138] Please see Figure 6 According to some embodiments of this application, the connecting part 3 may include a frame 35 and an elastic layer 36. The frame 35 has a gap and the main body of the frame 35 may be hollow. The elastic layer 36 wraps around the frame 35.

[0139] Frame 35 serves as the rigid support skeleton for connector 3, providing structural strength and stability. The main body of frame 35 is hollowed out, meaning that multiple perforations are formed in the wall surface of frame 35, allowing the wall to be partially hollowed out while maintaining overall structural integrity. These perforations penetrate the wall surface of frame 35, connecting the interior and exterior. Despite the hollowed-out main body, frame 35 remains rigid overall, but the hollowed-out areas allow the wall surface to undergo a certain degree of bending deformation when subjected to pressure along the thickness direction of the display panel PNL, thus giving frame 35 a limited elastic deformation capability.

[0140] Meanwhile, the space formed by the perforated holes provides ample room for elastic deformation of the elastic layer 36. When the connecting part 3 is subjected to external pressure, the elastic layer 36 deforms into the perforated holes, while the perforated wall of the frame 35 bends and deforms. The combined effect of these two factors compresses the connecting part 3 as a whole in the thickness direction. When the external pressure decreases, the elastic layer 36 recovers elastically, and the perforated wall of the frame 35 also recovers, causing the connecting part 3 to spring back as a whole. Through the composite structure of the perforated frame 35 and the elastic layer 36, the connecting part 3 achieves the function of elastic deformation along the thickness direction.

[0141] The perforations are evenly distributed on the walls of the frame 35. In some embodiments, the frame 35 is a cuboid box structure, with multiple perforations on the top, bottom, and / or side walls. The perforations can be circular, elliptical, rectangular, rhomboid, hexagonal, or other geometric shapes. The distribution and size of the perforated areas can be set according to the required support stiffness and elastic deformation space. A higher perforation rate results in a relatively lower rigidity of the frame 35 but an enhanced elastic deformation capacity, while also increasing the deformation space of the elastic layer 36 and improving the overall elasticity of the connection part 3. Conversely, a lower perforation rate results in a stronger rigidity of the frame 35 and better support stability.

[0142] In some embodiments, the frame 35 is made of a metal material, such as stainless steel or titanium alloy, which has excellent rigidity and fatigue resistance, ensuring the high load-bearing capacity of the support 10.

[0143] The elastic layer 36 wraps around the frame 35, covers the wall surface of the frame 35, and fills at least a portion of the perforated holes. The elastic layer 36 is used to elastically deform when the connection part 3 is subjected to pressure, absorb and buffer external loads, and return to its initial shape when the pressure is released, thereby realizing the elastic expansion and contraction of the connection part 3 along the thickness direction.

[0144] The elastic layer 36 creates a rigid-flexible composite structure between the frame 35 and the elastic layer 36. The metal or rigid plastic frame 35 provides stable support and stress dispersion, while the elastic layer 36 provides elastic deformation and cushioning. The elastic layer 36 can be made of a material with good elasticity and temperature and corrosion resistance. In some embodiments, the elastic layer 36 can be made of fluororubber, which has excellent temperature resistance, chemical corrosion resistance, and good elasticity. In other embodiments, the elastic layer 36 is made of silicone rubber, EPDM rubber, or polyurethane elastomer. The elastic layer 36 can completely cover the frame 35, meaning the elastic layer 36 covers the entire outer surface of the frame 35 and fills all the perforations, so that the frame 35 is completely enclosed within the elastic layer 36; or the elastic layer 36 can partially cover the frame 35, meaning the elastic layer 36 covers a portion of the outer surface of the frame 35 and fills at least some of the perforations.

[0145] In some embodiments, the frame 35 and the elastic layer 36 are seamlessly fused together through a vulcanization bonding process. That is, the elastic layer 36 is in contact with the surface of the frame 35 in its unvulcanized state. After heating and pressurizing for vulcanization, a strong chemical bond is formed between the elastic layer 36 and the surface of the frame 35, achieving an integrated connection at the interface without the need for additional fixing structures, thus ensuring the integrity and stability of the interface connection. In other embodiments, the frame 35 and the elastic layer 36 are combined through injection molding. That is, the frame 35 is placed as an insert in an injection mold, and the elastic layer 36 material is injection molded onto the surface of the frame 35 and fills the perforated holes.

[0146] When the gap between the display module 100 and the external components changes or when subjected to impact loads, the external load is transmitted to the elastic layer 36 of the connecting part 3 through the second support part 2. Under pressure, the elastic layer 36 undergoes elastic deformation into the hollowed-out holes of the frame 35, while the hollowed-out wall of the frame 35 undergoes bending deformation, and the connecting part 3 as a whole is compressed in the thickness direction. During this process, the rigid frame 8 of the frame 35 evenly distributes the pressure to the entire contact area, making the stress distribution of the bonding area PNL2 of the display panel PNL or the IC packaging area of ​​the driver chip balanced. At the same time, the modulus difference between the metal or rigid plastic frame 35 and the elastic layer 36 creates a damping effect, which can efficiently absorb impact and vibration energy. When the external load decreases, the elastic layer 36 recovers elastically, the hollowed-out wall of the frame 35 also recovers, and the connecting part 3 as a whole rebounds. The hollow frame 35 enables the support member 10 to have a certain elastic deformation capability while having a rigid support skeleton. Combined with the covering of the elastic layer 36, a rigid-flexible composite structure with both support stability and buffering and vibration absorption performance is formed.

[0147] According to some embodiments of this application, the elastic layer 36 has wear-resistant layers on both sides in the thickness direction of the display panel PNL.

[0148] A wear-resistant layer is disposed on both sides of the elastic layer 36 along its thickness direction, covering the upper and lower surfaces of the elastic layer 36 facing away from the frame 35. The wear-resistant layer reduces the coefficient of friction of the elastic layer 36, allowing the support member 10 to slide or adjust smoothly relative to the backlight side surface of the display panel PNL and the surfaces of external components during assembly into the display module 100. This prevents the support member 10 from being improperly installed or wrinkles from forming during assembly due to excessive frictional resistance. Simultaneously, the wear-resistant layer also protects the surface of the elastic layer 36, preventing wear or scratches from occurring when it rubs against the passivation layer of the display device or other components during assembly or use. It also prevents material debris from the elastic layer 36 from contaminating the internal environment of the display module 100 or damaging the display device. The wear-resistant layer provides good lubricity and wear resistance to the surface of the support member 10, while protecting the structural integrity of the elastic layer 36 and preventing scratches on the passivation layer of the display device.

[0149] In some embodiments, the wear-resistant layer can be a polytetrafluoroethylene-modified rubber layer. Polytetrafluoroethylene has an extremely low coefficient of friction and good self-lubricating properties. When it is modified by combining it with rubber and then coated on the surface of the elastic layer 36, it can provide excellent lubrication and form good adhesion with the rubber material of the elastic layer 36, thus preventing the wear-resistant layer from falling off during use.

[0150] Please see Figure 7 According to some embodiments of this application, the gap may include a plurality of elastic holes 37, which may penetrate the connecting portion 3 along the thickness direction of the display panel PNL, and the plurality of elastic holes 37 may be evenly distributed along the extension direction of the plane where the support member 10 is located.

[0151] The elastic hole 37 is a through-hole structure, and its axis extends along the thickness direction of the display panel PNL. The two surfaces of the connecting part 3 in the thickness direction are interconnected through the elastic hole 37. The elastic holes 37 are evenly distributed along the extension direction of the plane where the support member 10 is located, which means that multiple elastic holes 37 are arranged at approximately equal intervals in a plane perpendicular to the thickness direction.

[0152] The uniform distribution of multiple elastic holes 37 allows the area corresponding to each elastic hole 37 to deform synchronously when the connecting part 3 is subjected to external pressure, thereby ensuring that the compression deformation of each area of ​​the connecting part 3 is consistent and the support force is evenly distributed.

[0153] Multiple elastic holes 37 can be arranged in a matrix. The number of elastic holes 37 is not limited. The specific number can be set according to the area of ​​the connecting part 3, the required support stiffness, and the deformation stroke.

[0154] The cross-sectional shape of each elastic hole 37 in a plane perpendicular to the thickness direction can be circular, elliptical, rectangular, rhomboid, hexagonal, or other geometric shapes. In some embodiments, the elastic hole 37 is a cylindrical hole, that is, the cross-section of the elastic hole 37 in a plane perpendicular to the thickness direction is circular, and the cross-sectional dimensions and depth of each elastic hole 37 are consistent. In other embodiments, the cross-sectional dimensions of each elastic hole 37 may not be exactly the same. For example, the diameter of the elastic hole 37 located in the edge region of the connecting portion 3 may be smaller than the diameter of the elastic hole 37 located in the central region, so as to adjust the support stiffness of different regions. The diameter and wall thickness of the elastic hole 37 determine the deformation capacity of the elastic hole 37 under pressure.

[0155] In this embodiment, the connecting portion 3, the first support portion 1, and the second support portion 2 can be integrally formed. The integrally formed elastic structure has two opposing surfaces along the thickness direction, one surface constituting the first support portion 1 and the other surface constituting the second support portion 2. In other words, the support member 10 is an integral elastic structure, the connecting portion 3 constitutes the main body of the elastic structure, and its two side surfaces in the thickness direction serve as the first support portion 1 and the second support portion 2, respectively, for contacting the connecting layer SCF and the second backing film BF2.

[0156] This one-piece molding structure simplifies the overall structure of the support member 10, eliminating the need for additional connection or assembly processes, which helps reduce manufacturing costs and improve structural consistency. The one-piece molded elastic structure can be manufactured by injection molding, compression molding, or extrusion molding. In some embodiments, the support member 10 is integrally molded in one step by injection molding, and the elastic hole 37 is formed during the injection molding process by a core or core-pulling mechanism.

[0157] The main material of the integrally molded elastic structure can be a rubber material with excellent elastic recovery and aging resistance. In some examples, the main body of the support 10 can be made of hydrogenated nitrile butadiene rubber, which has good oil resistance, heat resistance, and excellent elastic recovery. Reinforcing agents and coupling agents can also be added to the rubber substrate to enhance structural strength and tear resistance. In some embodiments, carbon black reinforcing agents are added to the rubber substrate, which can significantly improve the tensile strength, tear strength, and abrasion resistance of the rubber. In other embodiments, silane coupling agents are added to the rubber substrate, which can improve the compatibility between the rubber material and the contact surface, avoid cracking or deformation during long-term use, and ensure the structural stability of the support 10.

[0158] When an external load is applied to the support member 10, the load is transmitted to the connecting part 3 through the first support part 1 or the second support part 2. Under pressure, the walls of the multiple elastic holes 37 undergo uniform elastic deformation, the volume of each elastic hole 37 decreases, and the connecting part 3 is compressed in the thickness direction. The distance between the first support part 1 and the second support part 2 decreases, thereby adaptively compensating for the assembly gap between the display module 100 and the external components. During this process, the structure of the elastic holes 37 penetrating the connecting part 3 along the thickness direction causes the air inside the elastic holes 37 to be compressed when the connecting part 3 is under pressure, forming a gas damping effect. This damping effect works synergistically with the viscoelastic deformation of the elastic structure itself to efficiently absorb impact energy and significantly attenuate vibration transmission, effectively reducing abnormal noise of the entire machine. When the external load decreases, the walls of the elastic holes 37 recover due to the elasticity of the material itself, the volume of each elastic hole 37 increases, and the connecting part 3 rebounds as a whole. With the uniform distribution and synchronous deformation of multiple elastic holes 37, the contact pressure is evenly distributed on the entire smooth contact surface of the support 10, which can fundamentally avoid problems such as mold printing, adhesive peeling and passivation layer damage in display devices, and can perfectly adapt to the application requirements of ultra-thin display module 100 without changing the existing assembly process.

[0159] Please see Figure 7 According to some embodiments of this application, the gap may also include multiple connecting holes, and adjacent elastic holes 37 can be connected through the connecting holes.

[0160] A connecting hole is located inside the connecting part 3 to connect adjacent elastic holes 37, creating a gas flow channel between the multiple elastic holes 37. The connecting hole ensures that adjacent elastic holes 37 are not completely independent closed spaces, but rather interconnected, forming a unified multi-hole interconnected structure. When the connecting part 3 is subjected to external pressure, the gas in each elastic hole 37 can flow freely between adjacent elastic holes 37 through the connecting hole, thereby balancing the gas pressure within each elastic hole 37 and preventing uneven distribution of support force due to excessive or insufficient compression of some elastic holes 37. The presence of the connecting hole allows the multiple elastic holes 37 to work collaboratively during deformation, resulting in more consistent compression of each elastic hole 37 and more uniform and stable overall deformation of the support member 10.

[0161] In some embodiments, the connecting holes are microporous structures formed inside the connecting portion 3, meaning that the rubber substrate of the connecting portion 3 itself is porous, and there are a large number of fine pores inside the substrate. These micropores serve as connecting holes to connect adjacent elastic holes 37. In other embodiments, the connecting holes are through channels formed during the molding process of the connecting portion 3 by means of a mold or post-processing, such as through grooves or through holes opened between the hole walls of adjacent elastic holes 37.

[0162] The number and distribution of the connecting holes can be set according to the desired connectivity effect. In some embodiments, a connecting hole is provided between every two adjacent elastic holes 37, so that all elastic holes 37 are interconnected to form a complete gas flow network. In other embodiments, connecting holes are provided only between some adjacent elastic holes 37, forming multiple independent interconnection groups.

[0163] The connecting holes and elastic holes 37 together form the void structure inside the connecting part 3. When an external load is applied to the support member 10, the wall of the elastic hole 37 deforms, the volume of the elastic hole 37 decreases, and the internal gas is compressed and flows through the connecting holes to adjacent elastic holes 37 or to the outside. The connection holes allow the gas to redistribute among the elastic holes 37, thereby achieving pressure equalization and keeping the pressure in each elastic hole 37 basically consistent, ensuring uniform support force in all areas of the support member 10. At the same time, the gas generates viscous resistance when flowing through the connection holes, further enhancing the damping effect and improving the attenuation capability of the support member 10 for high-frequency vibrations. When the external load is removed, the gas flows back through the connection holes, and each elastic hole 37 synchronously returns to its initial state. The connection holes enable the support member 10 to maintain good elastic deformation capability while also having better force distribution uniformity and vibration attenuation performance.

[0164] According to some embodiments of this application, gaps are provided within the support member 10. Utilizing its own elasticity and the compression of the gaps, it has multiple beneficial effects: balancing contact pressure, improving mold / top-print integrity, enhancing encapsulation sealing, and eliminating display malfunctions; matching the overall module modulus, eliminating looseness and resonance, preventing various abnormal noises, and resisting aging; adapting to the mass production of ultra-thin modules without modifying existing processes, reducing costs and increasing efficiency; simultaneously improving the integrity of the display module 100, the compatibility of the driver chip IC, and the overall noise level, significantly improving product reliability, service life, and market competitiveness.

[0165] Please see Figure 8 and Figure 9 According to some embodiments of this application, the connecting portion 3 may include a third connecting portion 38 and a fourth connecting portion 39. The third connecting portion 38 extends along the thickness direction of the display panel PNL, one end of the third connecting portion 38 is connected to the second support portion 2, and the other end passes through the first support portion 1. The third connecting portion 38 has a plurality of mounting positions distributed along the thickness direction of the display panel PNL. The fourth connecting portion 39 can be connected to any mounting position of the third connecting portion 38, and the fourth connecting portion 39 abuts against the side of the first support portion 1 facing the second support portion 2.

[0166] The third connecting part 38 is a longitudinal member extending along the thickness direction of the display panel PNL. One end of it is fixedly connected to the second support part 2, and the other end passes through the first support part 1 and extends to the side of the first support part 1 opposite to the second support part 2.

[0167] The third connecting portion 38 has multiple mounting positions, which are distributed along the thickness direction of the display panel PNL, meaning that each mounting position is at a different height position in the extension direction of the third connecting portion 38. The fourth connecting portion 39 can be selectively connected to any mounting position of the third connecting portion 38. When the fourth connecting portion 39 is connected to a certain mounting position, the fourth connecting portion 39 has a defined height position relative to the second support portion 2.

[0168] The fourth connecting part 39 abuts against the side of the first support part 1 facing the second support part 2, that is, the fourth connecting part 39 is located on the side of the first support part 1 facing the second support part 2, and the surface of the fourth connecting part 39 facing the first support part 1 is in contact with the surface of the first support part 1 facing the second support part 2. The third connecting part 38 extends from the second support part 2, passes through the first support part 1, and extends to the side of the first support part 1 facing away from the second support part 2. The fourth connecting part 39 connects to the third connecting part 38 at a position below the first support part 1, supporting the first support part 1 and thus restricting the movement of the first support part 1 along the direction of the third connecting part 38 towards the second support part 2. By installing the fourth connecting part 39 at different installation positions of the third connecting part 38, the position of the fourth connecting part 39 relative to the second support part 2 can be changed, thereby adjusting the distance between the first support part 1 and the second support part 2.

[0169] In some embodiments, the outer peripheral wall of the third connecting portion 38 may have multiple slots arranged along the thickness direction, each slot extending circumferentially along the third connecting portion 38. The fourth connecting portion 39 is a retaining spring or retaining ring, which can be engaged into any of the slots to achieve a fixed connection. In other embodiments, the third connecting portion 38 may have multiple pin holes arranged along the thickness direction, and the fourth connecting portion 39 is a pin, which can be inserted into any of the pin holes to achieve a connection. In still other embodiments, the third connecting portion 38 may have multiple positioning protrusions arranged along the thickness direction, and the fourth connecting portion 39 may have positioning grooves that mate with the positioning protrusions, achieving a connection through the engagement of the positioning protrusions and positioning grooves. The number of installation positions can be set according to the required adjustment precision; the more positions, the higher the adjustment precision.

[0170] When the support member 10 has multiple connecting parts 3, the third connecting part 38 and the fourth connecting part 39 of each connecting part 3 can be adjusted independently. Since the internal gaps of different display modules 100 or different display devices 1000 may differ at different locations, or the assembly gap requirements of different product models may differ, the installation position of the fourth connecting part 39 on each connecting part 3 can be adjusted to make the distance between the first support part 1 and the second support part 2 at different locations of the connecting part 3 different. This results in the support member 10 exhibiting different thickness distributions overall, adapting to the specific gap requirements at different locations. This independent adjustment capability allows the same support member 10 structure to be applicable to various product models and assembly tolerance ranges, significantly improving the versatility and design flexibility of the support member 10, eliminating the need to redesign and manufacture the support member 10 for each application scenario.

[0171] The mating structure of the third connecting part 38 and the fourth connecting part 39 enables the support member 10 to possess both structural stability and a flexibly adjustable support thickness. Compared to solutions that rely on elastic deformation to adapt to gaps, this embodiment achieves precise setting of the distance between the first support part 1 and the second support part 2 through mechanical installation position selection and fixing. This offers high adjustment accuracy, high support rigidity, and good long-term stability, making it particularly suitable for applications requiring high support accuracy and long-term reliability. During assembly, operators can quickly adjust the thickness of the support member 10 by selecting the corresponding installation position for the fourth connecting part 39 based on actual assembly gap measurements, eliminating the need for complex equipment and processes and providing excellent operational convenience.

[0172] Please see Figure 8 and Figure 9 According to some embodiments of this application, the support member 10 may further include a third liner 6, which may be connected to the side of the second support 2 facing the first support 1, and the third connecting part 38 may be connected to the third liner 6.

[0173] The third liner 6 is disposed on the surface of the second support 2 facing the first support 1, and is used to provide an installation base for the third connecting part 38, while uniformly transmitting the force on the third connecting part 38 to the second support 2. One end of the third connecting part 38 is connected to the second support 2. Specifically, the third connecting part 38 is indirectly connected to the second support 2 through the third liner 6.

[0174] The third backing plate 6 ensures that the connection between the third connecting part 38 and the second support part 2 is no longer limited to point contact or small-area contact. Instead, the connecting force and supporting force of the third connecting part 38 are distributed over a larger area of ​​the second support part 2 through the third backing plate 6. Since the second support part 2 is made of a soft material, when the third connecting part 38 is directly connected to the second support part 2, the third connecting part 38 may partially sink into the second support part 2 under stress, causing localized indentations or damage to the second support part 2. This damage may even be transmitted to the bonding area PNL2 of the second back film BF2 or the display panel PNL. By providing the third backing plate 6, the installation force of the third connecting part 38 and the supporting force transmitted to the second support part 2 are both distributed through the third backing plate 6, avoiding localized stress concentration and protecting the structural integrity of the second support part 2.

[0175] The third liner 6 can be made of a rigid material. In some embodiments, the third liner 6 is made of a metallic material, such as a stainless steel sheet, an aluminum sheet, or a copper sheet, which has high hardness and good thermal conductivity.

[0176] In some embodiments, the third connecting portion 38 and the third liner 6 are integrally formed, with the third connecting portion 38 extending upward from the surface of the third liner 6. In other embodiments, the third connecting portion 38 and the third liner 6 are fixedly connected by means of welding, bonding, or threaded connection.

[0177] Please refer to the figure. Figure 10 and Figure 11 According to some embodiments of this application, the support member 10 may further include a fourth liner 7, which may be connected to the side of the first support 1 facing the second support 2, the third connecting part 38 may pass through the fourth liner 7, and the fourth connecting part 39 may abut against the fourth liner 7.

[0178] A fourth liner 7 is disposed on the surface of the first support portion 1 facing the second support portion 2, providing a supporting base for the abutment between the fourth connecting portion 39 and the first support portion 1. A third connecting portion 38 extends along the thickness direction of the display panel PNL and penetrates the fourth liner 7. The mounting position of the fourth connecting portion 39 on the third connecting portion 38 is located on the side of the fourth liner 7 facing away from the first support portion 1 (i.e., below the fourth liner 7), with the surface of the fourth connecting portion 39 facing the first support portion 1 abutting against the surface of the fourth liner 7 facing away from the first support portion 1. When the fourth connecting portion 39 is installed at a certain mounting position of the third connecting portion 38, the fourth connecting portion 39 abuts against the lower surface of the fourth liner 7 through its upper surface, transferring the load borne by it to the first support portion 1 via the fourth liner 7.

[0179] The fourth liner 7 ensures that the contact between the fourth connecting part 39 and the first support part 1 no longer occurs directly between the fourth connecting part 39 and the flexible first support part 1, but rather through the fourth liner 7 acting as an intermediate load-bearing component. Since the fourth connecting part 39 is a rigid structure, its contact area with the first support part 1 is small when they directly contact each other, making it prone to localized indentations or damage. This indentation or damage could even be transmitted to the display area PNL1 of the display panel PNL through the connecting layer SCF. The fourth liner 7, as a rigid thin plate, has a much larger area than the contact area between the fourth connecting part 39 and the first support part 1. It can convert the concentrated load transmitted from the fourth connecting part 39 into a uniformly distributed load on the first support part 1, effectively suppressing plastic deformation of the first support part 1, protecting its structural integrity, and preventing the indentation or damage from being transmitted to the display area PNL1 of the display panel PNL.

[0180] The fourth liner 7 may be made of the same or different rigid material as the third liner 6. In some embodiments, the fourth liner 7 is made of a metallic material, such as a sheet of stainless steel, aluminum, or copper.

[0181] Please refer to the figure. Figure 8 , Figure 9 , Figure 10 and Figure 11 According to some embodiments of this application, the third connecting part 38 can be a screw, and the fourth connecting part 39 can be a nut, with the nut threadedly engaged with the screw.

[0182] The screw extends along the thickness direction of the display panel PNL. One end of the screw is connected to the second support part 2 (specifically, indirectly connected to the second support part 2 through the third liner 6), and the other end passes through the first support part 1 and extends to the side of the first support part 1 opposite to the second support part 2. The outer peripheral wall of the screw is provided with external threads, which are distributed along the length direction of the screw. The positions where the external threads are located are the installation positions.

[0183] The nut has an internal thread that matches the external thread. The nut can be screwed into the end of the screw extending from the first support part 1, and by rotating the nut, it can be moved along the axis of the screw, thus positioning the nut at any height on the screw. After the nut is tightened on the screw, the surface of the nut facing the first support part 1 abuts against the first support part 1, supporting the first support part 1 at the desired height position through the engagement of the threaded pair. By rotating the nut to different positions on the screw, the distance between the first support part 1 and the second support part 2 can be precisely adjusted, thereby achieving flexible adjustment of the support thickness of the support member 10.

[0184] The threaded fit structure makes the thickness adjustment of the support 10 simple and precise. During assembly, the operator screws the nut to the corresponding position on the screw according to the required support thickness. After tightening, the nut and screw maintain a fixed position due to the self-locking property of the threaded pair. When the gap between the display module 100 and the external components changes, the distance between the first support 1 and the second support 2 remains constant due to the rigid threaded fit between the nut and screw, preventing unexpected changes caused by vibration or impact and providing stable support force output.

[0185] Through the surface contact force transmission characteristics of the threaded pair, when an external impact load acts on the support 10, the impact energy is transmitted to the screw through the second support 2, and then to the nut and the first support 1 via the thread profile of the threaded pair. The contact of the threaded pair is surface contact, with a contact area much larger than that of point or line contact. During the transmission process, the impact energy is converted into compressive stress of the thread profile and evenly distributed along the helix, avoiding stress concentration in local point or line areas. This effectively reduces the local peak stress of the threaded pair and reduces the risk of plastic deformation or fatigue damage to the thread profile. Furthermore, the threaded pair has excellent self-locking characteristics. When the nut is tightened to the required position, the friction angle of the threaded pair is greater than the thread helix angle, ensuring that the nut will not undergo unexpected rotation or axial displacement under vibration and impact environments, thus ensuring continuous structural stability. The rigid threaded fit between the screw and the nut is a rigid transmission mechanism, which decouples the impact energy dissipation and structural positioning functions. The positioning function is guaranteed by the precise pitch and self-locking characteristics of the threaded pair, while the energy dissipation function is achieved by the surface contact compressive stress distribution of the thread profile. The two do not interfere with each other. This decoupled design ensures the precise height adjustment of the support component 10 while significantly improving its fatigue resistance and long-term reliability under continuous impact conditions.

[0186] Understandably, when the support member 10 has multiple connecting parts 3, the screws and nuts in each connecting part 3 can be adjusted independently. By rotating each nut to different positions on the corresponding screw, the distance between the first support part 1 and the second support part 2 at different locations of the connecting parts 3 can be made different to accommodate clearance requirements at different positions. The independent adjustment of multiple screws and nuts allows the same support member 10 structure to flexibly adapt to various product models and assembly tolerances, significantly improving the versatility of the support member 10.

[0187] Please see Figures 8-11 According to some embodiments of this application, the support member 10 includes a plurality of connecting portions 3, which are evenly distributed along the extension direction of the plane on which the support member 10 is located; wherein, the installation position of the fourth connecting portion 39 of at least one connecting portion 3 is different from the installation position of the fourth connecting portion 39 of the other connecting portions 3. Its working principle can be referred to the foregoing embodiments, and will not be repeated here.

[0188] According to some embodiments of this application, both the first support portion 1 and the second support portion 2 can be elastically deformable.

[0189] The first support portion 1 and the second support portion 2 are structural parts of the support member 10 that respectively abut against the connecting layer SCF and the second back film BF2. Both are elastically deformable, meaning that the first support portion 1 and the second support portion 2 can undergo elastic compression when subjected to pressure along the thickness direction of the display panel PNL, and can return to their initial shape after the pressure is released. By setting the first support portion 1 and the second support portion 2 as elastically deformable structures, the support member 10 further enhances its overall buffering and vibration absorption capabilities while providing structural support.

[0190] When an external load is transferred to the first support 1 through the connecting layer SCF, the elastic deformation of the first support 1 absorbs part of the impact energy and distributes the remaining load more evenly to the connecting layer SCF and the display area PNL1 of the display panel PNL, preventing the rigid support from directly impacting the display panel PNL. When an external load is transferred to the second support 2 through the second back film BF2, the elastic deformation of the second support 2 absorbs part of the impact energy and distributes the remaining load more evenly to the second back film BF2 and the bonding area PNL2, preventing the rigid support from directly acting on the bonding area PNL2 and the driver chip IC packaging area. The elastic deformation of the first support 1 and the second support 2, together with the elastic deformation of the connecting part 3, forms a multi-level buffer mechanism, further improving the support member 10's ability to absorb and dissipate impact energy.

[0191] In some embodiments, the first support portion 1 and the second support portion 2 are made of elastic materials, such as silicone rubber, polyurethane elastomers, thermoplastic elastomers, hydrogenated nitrile rubber, or methyl vinyl silicone rubber. These materials have excellent elastic recovery and fatigue resistance, and can maintain stable elastic deformation capacity during long-term use. In other embodiments, the first support portion 1 and the second support portion 2 are integrally molded from the same material as the connecting portion 3, and the overall elastic deformation is achieved through the continuous distribution of the same material in different structural regions.

[0192] The degree of elastic deformation of the first support part 1 and the second support part 2 can be adjusted by the hardness, thickness and structural form of the material.

[0193] The elastic deformability of the first support portion 1 and the second support portion 2 works synergistically with the function of the connecting portion 3. In embodiments where the connecting portion 3 employs an elastic structure (such as a spring, airbag, or a composite structure of a hollow frame 35), the elastic deformation of the first support portion 1 and the second support portion 2, along with the elastic deformation of the connecting portion 3, constitutes a multi-stage elastic system in series. When an external load acts on the support member 10, the load passes sequentially through the elastic deformation of the second support portion 2, the elastic deformation of the connecting portion 3, and the elastic deformation of the first support portion 1. Each stage absorbs and dissipates some of the impact energy, thereby significantly reducing the final impact force transmitted to the display panel PNL. In embodiments where the connecting portion 3 employs a rigid adjustment structure (such as a screw and nut combination), the elastic deformation of the first support portion 1 and the second support portion 2 compensates for the inability of the rigid connecting portion 3 to actively buffer the impact. Through the elastic deformation of the support portion itself, a flexible contact interface is provided between the display module 100 and the external components, preventing the load of the rigid connecting portion 3 from being directly and centrally transmitted to the display panel PNL or the external components. This also helps to absorb and buffer some of the impact energy, improving the reliability of the support member 10 under impact conditions.

[0194] The elastically deformable design of the first support portion 1 and the second support portion 2 also offers advantages in assembly compatibility. During the assembly of the support member 10 to the display module 100, due to the elastic deformation capability of the first support portion 1 and the second support portion 2, even if there is a slight deviation between the actual gap between the display module 100 and the external components and the preset value, the first support portion 1 and the second support portion 2 can absorb the deviation through their own elastic deformation, ensuring a good contact fit between the support member 10, the display panel PNL, and the external components, and avoiding assembly difficulties or support failure caused by gap deviation.

[0195] Please see Figure 12 and Figure 13 According to some embodiments of this application, the display module 100 further includes a driver chip IC, which is connected to the side of the bonding area PNL2 away from the display area PNL1; the support member 10 includes a first region 10a and a second region 10b, the orthographic projection of the first region 10a on the bonding area PNL2 overlaps with the orthographic projection of the driver chip IC on the bonding area PNL2, and the hardness of the first region 10a is greater than the hardness of the second region 10b.

[0196] The driver chip IC provides driving signals to the display panel PNL, controlling the light-emitting devices within the display area PNL1 to display images. The driver chip IC is connected to the side of the bonding area PNL2 facing away from the display area PNL1; that is, the driver chip IC is disposed on the surface of the bonding area PNL2 opposite to the display area PNL1. After the bending area PNL3 of the display panel PNL is bent, the bonding area PNL2 folds over to the backlight side of the display area PNL1, and the driver chip IC is subsequently positioned on the backlight side of the display area PNL1.

[0197] The driver chip IC forms an electrical connection with the signal lines within the display panel PNL through bonding pads in the bonding area PNL2. In related technologies, the package of the driver chip IC is usually made of brittle materials (such as glass or ceramic), which are sensitive to external stress. When subjected to uneven pressure or impact loads, it is prone to package cracking, solder joint fatigue detachment, or even hidden damage to the chip body. Therefore, it is necessary to provide reasonable and suitable support for the area where the driver chip IC is located to protect the structural integrity of the driver chip IC.

[0198] The support member 10 includes a first region 10a and a second region 10b, which are distinct from each other within the plane of the support member 10. The orthographic projection of the first region 10a onto the bonding area PNL2 overlaps with the orthographic projection of the driver chip IC onto the bonding area PNL2. That is, the first region 10a corresponds to the position of the driver chip IC in the thickness direction. The first region 10a is located directly below or above the driver chip IC (depending on the viewing direction), so the supporting force provided by the first region 10a acts directly on the area where the driver chip IC is located. The second region 10b is any other region in the support member 10 besides the first region 10a, and its position corresponds to other regions besides the driver chip IC. The hardness of the first region 10a is greater than that of the second region 10b, meaning the first region 10a is harder than the second region 10b, providing greater supporting stiffness and stronger compressive strength.

[0199] The difference in hardness between the first region 10a and the second region 10b can be achieved in several ways. In some embodiments, the first region 10a and the second region 10b are made of the same base material but have different hardness grades. For example, the first region 10a and the second region 10b are made of silicone materials with different hardnesses, wherein the first region 10a is made of high-hardness silicone (e.g., Shore A70 to A90) and the second region 10b is made of low-hardness silicone (e.g., Shore A30 to A50). In other embodiments, the first region 10a and the second region 10b are made of different materials, with the first region 10a made of a material with higher hardness (e.g., polycarbonate or rigid polyurethane) and the second region 10b made of a less hard elastic material (e.g., foamed silicone or thermoplastic elastomer). In still other embodiments, the first region 10a and the second region 10b are made of the same material, but the first region 10a is hardened (e.g., by increasing the crosslinking density or adding reinforcing fillers) to make its hardness higher than that of the second region 10b. In some other embodiments, the thickness of the first region 10a is greater than the thickness of the second region 10b, resulting in the first region 10a exhibiting higher compressive stiffness and equivalent hardness under the same material conditions. The difference between the hardness of the first region 10a and the hardness of the second region 10b can be set according to the brittleness of the driver chip IC and the required support force distribution, and is not specifically limited.

[0200] By configuring the support member 10 into a first region 10a and a second region 10b with different hardnesses, and positioning the harder first region 10a corresponding to the location of the driver chip IC, the support member 10 can provide sufficient rigid support in the driver chip IC area. This ensures that the driver chip IC does not undergo excessive deformation under external pressure, effectively preventing the package from cracking or solder joints from falling off due to excessive deformation. Simultaneously, the softer second region 10b corresponds to the non-driver chip IC area, providing flexible buffering and balancing the overall contact pressure. This avoids excessive pre-pressure or molding on other areas of the display panel PNL due to excessive hardness. The hardness difference between the first region 10a and the second region 10b allows the support member 10 to provide differentiated support forces according to the structural characteristics and stress requirements of different areas of the display panel PNL. This satisfies the rigid support requirement of the driver chip IC area while also taking into account the flexible buffering requirements of other areas, achieving a balanced distribution of contact pressure.

[0201] In some embodiments, the first support portion 1 and the second support portion 2 are an integral structure, and their hardness distribution is consistent with the hardness distribution of the first region 10a and the second region 10b. Specifically, the hardness of the portion of the first support portion 1 corresponding to the first region 10a is greater than the hardness of the portion of the first support portion 1 corresponding to the second region 10b; the hardness of the portion of the second support portion 2 corresponding to the first region 10a is greater than the hardness of the portion of the second support portion 2 corresponding to the second region 10b. The support member 10 can be integrally molded by methods such as two-color injection molding, insert injection molding, or partition molding, so that the first region 10a and the second region 10b achieve different hardness distributions in a single component. This integral molding method eliminates the need for additional assembly processes, which is beneficial for maintaining the integrity of the support member 10 and its long-term reliability.

[0202] Please see Figure 13 According to some embodiments of this application, the support member 10 may further include a rigid frame 8, which may be disposed between the first support part 1 and the second support part 2, and the orthographic projection of the rigid frame 8 on the bonding area PNL2 overlaps with the orthographic projection of the driver chip IC on the bonding area PNL2.

[0203] The rigid frame 8 is a rigid structural component disposed inside the support member 10. It is located between the first support portion 1 and the second support portion 2, that is, the rigid frame 8 is sandwiched between the first support portion 1 and the second support portion 2 along the thickness direction of the display panel PNL. The rigid frame 8 is used to provide additional structural strength and support stiffness inside the support member 10, enhancing the compressive strength and structural stability of the support member 10 in a specific area. The orthographic projection of the rigid frame 8 on the bonding area PNL2 overlaps with the orthographic projection of the driver chip IC on the bonding area PNL2. That is, the rigid frame 8 corresponds to the position of the driver chip IC in the thickness direction. The rigid frame 8 is located directly below (or directly above) the driver chip IC, so that the enhanced support force provided by the rigid frame 8 acts directly on the area where the driver chip IC is located.

[0204] The rigid frame 8 provides the support component 10, located in the area of ​​the driver chip IC, with higher structural strength and compressive stiffness, effectively preventing excessive deformation or displacement of the driver chip IC under external pressure. When an external load is applied to the support component 10, the load is transferred to the rigid frame 8 through the first support part 1 and the second support part 2. The rigid frame 8, with its own rigidity, stably transmits and distributes the load, preventing excessive compression of the soft support component in the driver chip IC area due to excessive local stress, thus ensuring that the driver chip IC remains in a stable supported state. The rigid frame 8 is a specific way to achieve a higher hardness in the first region 10a than in the second region 10b. The first region 10a gains higher structural strength due to the built-in rigid frame 8, while the second region 10b, lacking the rigid frame 8, maintains relatively lower hardness.

[0205] Understandably, the rigid frame 8 can be provided only in the region corresponding to the driver chip IC (i.e., the first region 10a), while the second region 10b does not have the rigid frame 8. The second region 10b can adopt other structural forms, such as a closed cavity 34, elastic through-holes, foamed structures, or pure elastomer structures, to provide flexible cushioning. This selective arrangement allows the support member 10 to obtain targeted rigidity enhancement in the driver chip IC region, while maintaining flexible cushioning performance in other regions, thereby simultaneously meeting the rigid support requirements of the driver chip IC region and the flexible cushioning requirements of other regions.

[0206] The arrangement of the rigid frame 8 within the support member 10 can be combined with other functional structures of the support member 10. In some embodiments, when the connecting part 3 adopts a hollow frame 35 composite structure, the rigid frame 8 is the portion of the frame 35 structure located in the area corresponding to the driver chip IC, while other areas can be provided with an elastic layer 36 or a foam structure. In other embodiments, when the connecting part 3 adopts an airbag design, the rigid frame 8 is embedded inside the airbag structure and located only in the area corresponding to the driver chip IC. The closed cavity 34 in this area is partially occupied or surrounded by the rigid frame 8, while the cavities in other areas remain intact to provide cushioning. In still other embodiments, when the connecting part 3 adopts a porous elastomer design, the rigid frame 8 is embedded inside the elastomer and located only in the area corresponding to the driver chip IC. The size, density, or arrangement of the elastic holes 37 in this area differs from other areas to provide higher support stiffness. In some other embodiments, the rigid frame 8 can be set independently of the other structures of the connecting part 3, that is, an independent rigid plate or rigid frame 35 is sandwiched between the first support part 1 and the second support part 2 in the corresponding area of ​​the driver chip IC, and the rigid plate or rigid frame 35 is arranged side by side with the rest of the connecting part 3.

[0207] In some embodiments, the rigid frame 8 is a thin metal sheet, such as a stainless steel sheet, an aluminum sheet, or a titanium alloy sheet, which has high rigidity and good fatigue resistance. In still other embodiments, the rigid frame 8 can be a hollow structure, with perforations on the surface of the frame to reduce weight and allow for a certain degree of deformation fit.

[0208] Please see Figure 14 Based on the same concept, this application also provides a display device 1000. The display device 1000 includes the display module 100 in any of the foregoing embodiments.

[0209] Display device 1000 refers to an electronic device with image display function. Display module 100, as the core component of display device 1000, is used to realize the display of images.

[0210] The specific product form of the display device 1000 can be a mobile phone, tablet computer, in-vehicle display, smartwatch, virtual reality device, augmented reality device, laptop computer, television, electronic paper display, digital photo frame or advertising display screen, etc.

[0211] The display module 100 is assembled inside the mid-frame or housing of the display device 1000. External components may include the mid-frame, motherboard, battery, back cover, or other structural components disposed on the backlight side of the display module 100.

[0212] According to the display device 1000 provided in the embodiments of this application, by adopting the display module 100 in the above embodiments, the dynamic adaptability of the support member 10 to the gap between the display module 100 and external components allows the gap fluctuations caused by processor heating, ambient temperature changes, or vibration during use of the display device 1000 to be compensated in real time, effectively avoiding vibration and abnormal noise caused by support failure and display quality problems such as bright spots and water ripples caused by excessive pre-pressure of the display panel PNL. The adaptability of the support member 10 to different models and different assembly tolerances allows the same support member 10 structure to be applied to multiple display device 1000 products, reducing the overall design verification cycle and material management costs of the display device 1000. The buffering and vibration absorption capacity of the support member 10 can effectively absorb and dissipate impact energy when the display device 1000 is dropped or subjected to accidental impact, reducing the peak impact force transmitted to the display panel PNL, protecting the display panel PNL from cracking damage, and also protecting the driver chip IC package from cracking or solder joint detachment. The support member 10 provides targeted rigidity enhancement to the driver chip IC area, further improving the structural reliability and display stability of the display device 1000 during long-term use. Overall, the display device 1000 using the display module 100 provided in this application embodiment achieves significant improvements in structural stability, display quality, impact resistance, product versatility, and long-term reliability.
