Description

Technical Field

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

[0002] Televisions are evolving towards ultra-thin designs and integrated aesthetics. To accommodate the limited overall thickness, televisions need to incorporate display modules and related functional components within a small space in their structural design. Among these components, the back panel, as a key structure for supporting and securing internal parts, significantly influences the overall appearance design of the television.

[0003] However, in related technologies, the back panel of a TV is usually formed by stamping or pressing to create a pre-defined curved structure. This curvature is fixed during the manufacturing stage, which in turn constrains the shape and outline of the back of the TV, limiting the flexibility of the overall appearance design and making it difficult to meet the diverse shape design requirements of ultra-thin TVs. Summary of the Invention

[0004] This application provides a support structure, a backlight module, and a display device that can meet the diverse design requirements of ultra-thin TVs, thereby at least partially solving the aforementioned technical problems.

The supporting surface is inclined relative to the back plate, and the distance between the supporting surface and the back plate changes continuously along the length direction of the back plate. The number of the support members is multiple, and the multiple support members are configured to cause the reflective sheet to form a preset shape within the back plate when the support surface contacts the reflective sheet.

[0006] In some embodiments, the support member further includes a connecting portion that connects the fixing portion and the support portion; The connecting part and / or the supporting part can undergo elastic deformation under the action of the reflective sheet, so that the supporting surface keeps in contact with the reflective sheet and supports the reflective sheet.

[0008] In some embodiments, the support extends from the connection in a bending direction away from the curved section to form a cantilever structure.

[0009] In some embodiments, the support structure further includes an elastic element connected to the connecting portion, the elastic element being configured to contact the support member after the support member deforms to a preset angle, so as to provide elastic support to the support portion.

[0010] In some embodiments, the fixing part, the connecting part, and the supporting part are integrally formed.

[0011] In some embodiments, the elastic element is detachably connected to the connector.

[0012] In some embodiments, an angled region is formed between the curved section of the support and the connecting portion, and the elastic element is at least partially located within the angled region so as to contact the support after the support is deformed to a preset angle.

[0013] In some embodiments, the elastic element includes an elastic segment and an adjusting segment connected to each other, the adjusting segment being configured to undergo plastic deformation under external force to change the distance of the elastic segment relative to the support.

[0014] In some embodiments, a metal strip is provided within the adjustment section.

[0015] In some embodiments, the fixing part is fixedly connected to the back plate by adhesive.

[0016] In some embodiments, the support portion and the reflector are fixedly connected by adhesive.

[0017] In some embodiments, the fixing part is slidably connected to the connecting part of the support member, and an elastic reset key is provided between the fixing part and the connecting part. The direction in which the connecting part slides relative to the fixing part is a first direction. Along the first direction, the distance between the reflector and the back plate gradually increases or decreases.

[0018] In some embodiments, the support portion is elastically connected to the connecting portion of the support member, and the support portion has a first state and a second state; the support portion is configured to switch from the first state to the second state when the reflector is deformed by an external force; wherein, when the support portion is in the first state, the contact area between the support surface and the reflector is smaller than the contact area between the support surface and the reflector when the support portion is in the second state.

[0019] According to a second aspect of this application, a backlight module is provided, including the support structure described in the above technical solution, wherein a plurality of the support members are arranged in two groups along the width direction of the back plate, and the two groups of support members are symmetrically arranged with respect to the center line of the length direction of the back plate.

Detailed Implementation

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0028] According to the first aspect of this application, referring to Figures 1 to 6 This disclosure provides a support structure mounted on the backplate 10 of a display device to support a reflective sheet 20. By applying support to the reflective sheet 20 through the support structure, the reflective sheet 20 can maintain a preset shape within the backplate 10. Based on this structural configuration, the backplate 10 does not need to be prefabricated to match the shape of the reflective sheet 20, but can be configured according to the overall structure and appearance design requirements, with the support structure providing support and shape definition for the reflective sheet 20.

[0029] In some embodiments, refer to Figure 1 and Figure 3 The support structure includes a support member 100, which has a fixing portion 110 and a supporting portion 120 that are elastically connected to each other. The fixing portion 110 is used to connect to a back plate 10, and the supporting portion 120 has a supporting surface 121 for supporting a reflector 20. Exemplarily, the fixing portion 110 is disposed at one end of the support member 100 for connecting to the back plate 10 to position the support member 100 on the back plate 10; the supporting portion 120 is disposed at the other end of the support member 100 and has a supporting surface 121 for contacting the reflector 20 to provide support for the reflector 20.

[0030] In some embodiments, refer to Figure 2 and Figure 3The support surface 121 is inclined relative to the back plate 10, and the distance between the support surface 121 and the back plate 10 varies continuously along the length of the back plate 10. This "continuous variation" can be understood as the distance between the support surface 121 and the back plate 10 gradually increasing or decreasing along the length direction, or increasing first and then decreasing, thus forming a smoothly varying spatial contour. Through this structural arrangement, when the reflector 20 contacts the support surface 121, the support surface 121 can apply a distributed supporting effect to the reflector 20, which helps guide the reflector 20 to form a shape that matches the support surface 121 in the corresponding area.

[0031] In some embodiments, refer to Figure 4 and Figure 5 Multiple support members 100 are configured to cause the reflector 20 to form a preset shape within the back plate 10 when the support surface 121 contacts the reflector 20. When the support surfaces 121 of multiple support members 100 simultaneously contact the reflector 20, each support member 100 provides support to the reflector 20 at different positions, causing the reflector 20 to form a preset shape within the back plate 10. By adjusting the number of support members 100, their positions, and the tilt angle and spacing of the support surfaces 121 relative to the back plate 10, the shape of different areas of the reflector 20 can be defined accordingly, which is beneficial for achieving fine-tuning of the overall shape of the reflector 20.

[0032] In some embodiments, the fixing part 110 can be connected to the back plate 10 by adhesive, snap-fit ​​or screw connection; the supporting part 120 can be a plate structure, strip structure or other structural form suitable for contacting the reflector 20; the supporting surface 121 can be a plane, an arc surface or a curved surface structure with slight curvature changes.

[0033] In some embodiments, the support member 100 further includes a connecting portion 130, which connects the fixing portion 110 and the support portion 120. The connecting portion 130 can serve as a transition structure in the support member 100 for deformation, allowing the support portion 120 to have a certain elastic range of motion relative to the fixing portion 110.

[0034] In some embodiments, the connecting portion 130 and / or the supporting portion 120 can elastically deform under the force of the reflector 20, so that the supporting surface 121 remains in contact with the reflector 20 and supports the reflector 20. The aforementioned "elastic deformation" can be understood as displacement, bending, or angular change under external force, with a tendency to recover after the external force decreases or disappears. By providing the connecting portion 130 or the supporting portion 120 capable of elastic deformation, when the reflector 20 contacts the supporting surface 121 and is subjected to assembly stress or external load, the supporting portion 120 can adjust its position and / or orientation relative to the fixing portion 110, allowing the supporting surface 121 to better conform to the local surface morphology of the reflector 20. Through the aforementioned elastic deformation, the supporting portion 120 can also provide support for the reflector 20 while buffering the external force applied to the reflector 20, thereby reducing local stress concentration, which is beneficial for protecting the reflector 20 and maintaining the preset shape of the reflector 20 within the backplate 10.

[0035] Based on the above structural configuration, when there is a height difference or a certain degree of deformation in the reflector 20, the elastic deformation of the connecting part 130 and / or the supporting part 120 can provide flexible support for the reflector 20, which is beneficial to increase the contact area between the supporting surface 121 and the reflector 20, thereby dispersing the load acting on the reflector 20, reducing the local stress concentration phenomenon, and enabling the reflector 20 to maintain a relatively stable preset shape within the back plate 10.

[0036] In some embodiments, the connecting portion 130 may include a bent section, an arc-shaped section, a thin-walled section, or a structure with a thinned region to provide the expected elastic deformation capability; the supporting portion 120 may also possess a certain degree of elasticity by reducing its thickness, providing a groove, or using a flexible material. All of the above structural forms can be used to achieve the function of elastic deformation of the supporting member 100 under the force of the reflector 20.

[0037] In some embodiments, refer to Figure 3 and Figure 6 The connecting portion 130 includes a curved section 131 and a main body section 132 connected to each other. The curved section 131 is configured to undergo elastic deformation under external force. The curved section 131 is connected to the support portion 120 and is used to transfer the load acting on the support surface 121 to the main body section 132. Exemplarily, the main body section 132 is disposed on the side near the fixing portion 110 and is connected to the fixing portion 110 for fixing the support member 100 to the back plate 10; the curved section 131 is disposed between the main body section 132 and the support portion 120 and is connected to the support portion 120.

[0038] Specifically, when the support surface 121 is subjected to a force from the reflector 20, this force is transmitted through the support portion 120 to the bending section 131, causing the bending section 131 to bend or displace accordingly. This further transmits the load to the main body section 132 and then from the main body section 132 to the fixing portion 110. Through the above force transmission path, the support member 100 can provide support for the reflector 20 while achieving a certain degree of elastic buffering, which is beneficial for dispersing the load acting on the support surface 121.

[0039] In some embodiments, refer to Figure 3 and Figure 6 The bending section 131 can be an arc-shaped structure, a bent structure, or a structure with a thinned area to facilitate elastic deformation under external force; the main body section 132 can be a plate-like structure or a block-like structure to improve the structural stability at the connection with the fixing part 110. By rationally setting the shape, thickness, and material of the bending section 131, the elastic response characteristics of the support member 100 can be adjusted to adapt to different shapes of reflective sheets 20 and assembly requirements.

[0040] In some embodiments, refer to Figure 3 and Figure 6 The support portion 120 extends from the connecting portion 130 in a bending direction away from the bending section 131 to form a cantilever structure. The aforementioned "cantilever structure" can be understood as follows: one end of the support portion 120 is connected to the fixing portion 110 through the connecting portion 130, and the other end is in a relatively free state, used to contact the reflector 20 and support the reflector 20.

[0041] By configuring the support portion 120 as a cantilever structure, when the reflector 20 contacts the support surface 121 and a force is applied, the force is transmitted through the support portion 120 to the connecting portion 130, causing the bent section 131 in the connecting portion 130 to undergo corresponding elastic deformation. Compared to a non-cantilever structure, the cantilever structure has a longer lever arm when under force, which is beneficial for inducing displacement or bending response of the support portion 120 and the bent section 131 under a smaller force, thereby making the support structure more sensitive to changes in the force on the reflector 20.

[0042] Based on the above structural configuration, when the reflector 20 is subjected to a small external force during assembly or use, the cantilever support 120 can buffer the reflector 20 through its own displacement and the elastic deformation of the connecting part 130, which helps to reduce the instantaneous load locally borne by the reflector 20. Since the reflector 20 is usually a thin sheet structure, it is more sensitive to changes in external force. The above-mentioned cantilever support method helps to achieve flexible support and buffering of the reflector 20 without significantly increasing the structural complexity.

[0043] In some embodiments, refer to Figure 3 and Figure 6 The curved section 131 is an arc-shaped structure with continuously varying curvature. This arc-shaped structure helps to smoothly distribute the load borne by the support 120 and achieve elastic deformation under the force of the reflector 20. Through the continuous curvature design, the stress distribution of the curved section 131 is more uniform when bending or rotating, which can reduce local stress concentration and thus improve the service life and reliability of the support 100.

[0044] In practice, the curved segment 131 can be a single continuous arc or a combination of multiple continuously varying curvature arcs to adapt to different shapes and thicknesses of the reflective sheet 20. In an equivalent solution, the curved segment 131 can be formed from a flexible plastic sheet, a metal spring sheet, or a composite material, as long as it can provide similar elastic deformation and load transfer effects.

[0045] In some embodiments, refer to Figure 5 and Figure 6 The support structure also includes an elastic element 200, which is connected to the connecting portion 130. The elastic element 200 is configured to contact the support member 100 after the support member 100 deforms to a preset angle, so as to provide elastic support to the support portion 120. The aforementioned "preset angle" can be understood as the deformation angle threshold of the support member 100 relative to its initial state under the action of external force. This angle can be set according to the structural dimensions and material properties of the support member 100.

[0046] Specifically, in the initial stage when the reflector 20 applies a relatively small force, the support portion 120 mainly buffers the reflector 20 through the elastic deformation of the connecting portion 130 and / or the support portion 120 itself. At this time, the elastic element 200 has not yet come into contact with the support member 100, making the support structure as a whole exhibit a relatively sensitive and gentle buffering characteristic. As the force applied by the reflector 20 further increases, the support member 100 continues to deform and reaches the preset angle. At this point, the elastic element 200 comes into contact with the support member 100 and applies additional elastic support force to the support portion 120.

[0047] Through the aforementioned phased stress process, the elastic element 200 can participate in the support during the subsequent deformation stage, so that the load acting on the support part 120 can be further transferred to the connection part 130 through the elastic element 200. This helps to share the load borne by the support part 120, reduce the local stress level of the support part 120, and thus help to reduce the risk of wear and tear on the support part 120 during long-term stress or repeated deformation.

[0048] In some embodiments, refer to Figure 3 and Figure 6The fixing part 110, the connecting part 130, and the supporting part 120 are integrally formed. By integrally forming the fixing part 110, the connecting part 130, and the supporting part 120, the number of independent parts in the supporting structure can be reduced, the assembly process can be simplified, the manufacturing and assembly complexity can be reduced, and the performance of the supporting structure in terms of dimensional consistency and structural stability can be improved.

[0049] For example, the one-piece molded structure can be achieved through injection molding, compression molding, or other processes suitable for processing plastics or elastic materials. By adopting the above molding methods, the support structure can reduce subsequent assembly steps while ensuring structural functionality, thereby improving production efficiency and controlling overall manufacturing costs.

[0050] In some embodiments, refer to Figure 5 and Figure 6 The elastic element 200 and the connecting part 130 are detachably connected. By setting the elastic element 200 and the connecting part 130 as a detachable connection structure, it is convenient to select or change the type or elastic parameters of the elastic element 200 according to different usage requirements during the assembly stage. At the same time, when the elastic element 200 experiences fatigue or performance degradation, the elastic element 200 can be replaced individually without replacing the entire support structure, which helps to improve the maintenance convenience and usage flexibility of the structure.

[0051] For example, the detachable connection method may include snap-fit, threaded connection, plug-in fit, or connection by fasteners. Through the above connection methods, the elastic element 200 can achieve reliable installation and disassembly while meeting the requirements of stable connection, thereby ensuring the support effect and taking into account the maintainability of the structure.

[0052] In some embodiments, refer to Figure 5 and Figure 6 An angle region 122 is formed between the support portion 120 and the curved section 131 of the connecting portion 130. The elastic member 200 is at least partially located within the angle region 122 so that it contacts the support portion 120 after the support portion 120 deforms to a preset angle, thereby placing the elastic member 200 on the potential deformation path of the support portion 120.

[0053] Specifically, when the reflector 20 applies a force to the support 120, the support 120 undergoes elastic deflection under the action of the bending section 131 of the connecting section 130. In the initial stage of deformation, the support 120 has not yet come into contact with the elastic element 200, and the support 120 mainly relies on the elastic deformation of the bending section 131 itself for buffering. This allows the support 120 to displace under a relatively small load, which is beneficial for achieving flexible support for the reflector 20. As the support 120 continues to deform and reaches a preset angle, it comes into contact with the elastic element 200 located within the included angle region 122. The elastic element 200 participates in the force application and provides additional elastic support to the support 120, allowing the force to be gradually transmitted to the connecting section 130 and the fixing section 110 via the elastic element 200. Through the synergistic effect of the above structures, a phased force application and buffering process can be formed, which is beneficial for reducing the risk of localized stress concentration in the support 120 while ensuring support stability.

[0054] It should be understood that the aforementioned "preset angle" is not limited to a specific value, but can be designed and adjusted according to the length, thickness, material properties of the support 120 and the elastic parameters of the elastic element 200. By changing the position, size, or initial gap of the elastic element 200 within the included angle region 122, the contact timing between the support 120 and the elastic element 200 can be adjusted, thereby achieving different buffering characteristics.

[0055] In some embodiments, the elastic element 200 can be an elastic sheet, elastic pad, elastic block, or elastic tongue, and its material can be selected from rubber, silicone, thermoplastic elastomer, or engineering plastic with elastic recovery capability. The elastic element 200 can be entirely disposed within the included angle region 122, or only a portion of it can extend into the included angle region 122 to contact a local area of ​​the support portion 120 during deformation. Accordingly, the contact form between the support portion 120 and the elastic element 200 can be surface contact, line contact, or point contact. All of the above different contact forms can achieve elastic support for the support portion 120, which are equivalent variations of the present disclosure.

[0056] Furthermore, the specific shape of the included angle region 122 can be an acute angle region, an obtuse angle region, or an approximately arc-shaped transition region, as long as it can provide accommodating space for the elastic element 200 and is located within the deformation path of the support portion 120, the aforementioned staged buffering effect can be achieved. Through the rational design of the shape of the included angle region 122 and the structure of the elastic element 200, it is beneficial to improve the adaptability of the support structure to the reflector 20 and the structural reliability.

[0057] In some embodiments, refer to Figure 5 and Figure 6The elastic member 200 includes an elastic segment 210 and an adjusting segment 220 connected to each other. The adjusting segment 220 is configured to undergo plastic deformation under external force to change the distance between the elastic segment 210 and the support portion 120. The elastic segment 210 has elastic recovery capability and is used to provide elastic support to the support portion 120 after contacting it. The adjusting segment 220 is disposed between the elastic segment 210 and the connecting portion 130 and is configured to undergo plastic deformation under external force to change the spatial position of the elastic segment 210 relative to the support portion 120.

[0058] Specifically, when an external force is applied to the adjusting section 220, the adjusting section 220 undergoes an irreversible shape adjustment, causing a change in the initial distance between the elastic section 210 and the support portion 120. In this way, the elastic element 200 can be locally corrected during assembly or debugging, altering the timing of the intervention of the elastic section 210 during the deformation of the support portion 120, thereby affecting the contact stage and force path between the support portion 120 and the elastic element 200. Thus, support elements 100 at different locations can be differentiated using corresponding adjusting sections 220, which is beneficial for creating different buffer response characteristics on the same backplate 10 or the same reflector 20.

[0059] When the distance between the elastic segment 210 and the support portion 120 is small, the support portion 120 can contact the elastic segment 210 within a small deformation range, and the elastic element 200 participates in the force earlier, which is beneficial to improving the local support stiffness. When the distance is relatively larger, the support portion 120 mainly relies on its own and the elastic deformation of the connecting portion 130 for buffering in the initial stage, and the elastic segment 210 participates in the support in the subsequent deformation stage, which is beneficial to obtaining a softer initial buffering effect. By controlling the degree of plastic deformation of the adjusting segment 220, the buffering performance can be finely adjusted without changing the overall layout of the support structure.

[0060] It should be understood that the adjusting section 220 can undergo plastic deformation through bending, compression, or stretching, and its specific form can be selected according to material properties and installation space. For example, the adjusting section 220 can be configured as a thin-walled sheet structure, a corrugated structure, or a partially thinned structure to allow for controllable deformation under applied force. The elastic section 210 and the adjusting section 220 can be integrally formed or connected by riveting, snap-fitting, or welding.

[0061] In some embodiments, refer to Figure 5 and Figure 6A metal strip 221 is provided inside the adjusting section 220. The metal strip 221 is arranged along the extension direction of the adjusting section 220 and together with the adjusting section 220 forms a composite structure. By introducing the metal strip 221 into the adjusting section 220, the overall stiffness and plastic deformation characteristics of the adjusting section 220 can be controlled, making the adjusting section 220 more conducive to predictable shape adjustment under the action of external force.

[0062] For example, the body of the adjustment section 220 can be made of a material with a certain degree of toughness, while the metal strip 221 has relatively high strength and ductility. When an external force is applied to the adjustment section 220 for adjustment, the adjustment section 220 undergoes plastic deformation under the constraint and guidance of the metal strip 221. The metal strip 221 participates in bearing the load and restricts the deformation path, which helps to avoid local instability or disordered deformation of the adjustment section 220, thereby making the displacement change of the elastic section 210 relative to the support part 120 more stable and controllable. As a result, the consistency of different support members 100 during the adjustment process can be improved, making it easier to achieve fine-tuning of the buffering performance of the reflector 20.

[0063] Specifically, the metal strip 221 can maintain a certain structural strength after the adjustment section 220 deforms, so that the force transmitted through the elastic section 210 can be transmitted to the connection part 130 more smoothly. This helps to reduce the fatigue risk of the adjustment section 220 under long-term stress, thereby improving the reliability of the support structure under repeated stress.

[0064] It should be understood that the metal strip 221 can be a stainless steel strip, an aluminum alloy strip, or other metal components with plastic deformation capabilities, and its cross-sectional shape can be sheet-like, wire-like, or strip-like. The metal strip 221 can be entirely embedded inside the adjusting section 220, or it can be partially exposed and form a covering or clamping relationship with the adjusting section 220. The adjusting section 220 and the metal strip 221 can be fixed by means of adhesive coating, embedded molding, or bonding.

[0065] In some embodiments, the fixing part 110 is fixedly connected to the back plate 10 by adhesive bonding. By adhesive bonding, the fixing part 110 is disposed on the surface of the back plate 10, which facilitates the installation of the support structure without drilling or welding the back plate 10, thereby reducing the impact on the overall structural strength and appearance of the back plate 10 and facilitating the flexible design of the back plate 10's structural form.

[0066] Specifically, the adhesive bonding creates a continuous stress interface between the fixing part 110 and the back plate 10, allowing the load from the support part 120 to be transmitted to the fixing part 110 via the connecting part 130 and then distributed more evenly to the back plate 10, thus reducing local stress concentration. Simultaneously, the adhesive layer itself has a certain degree of elasticity; when the reflector 20 is subjected to external force, the adhesive layer can undergo slight deformation, thereby creating a buffer between the fixing part 110 and the back plate 10, which helps reduce the impact of impact loads on the support structure and the back plate 10.

[0067] For example, the adhesive method can be pressure-sensitive adhesive, structural adhesive, or double-sided adhesive, etc. The adhesive layer can cover the entire bonding area of ​​the fixing part 110, or it can be set as an intermittently distributed adhesive dots or tape structure, so as to meet the fixing strength requirements while taking into account the assembly convenience and cost control. Adhesive fixing also facilitates the adjustment of the position of the support member 100 on the back plate 10, which is beneficial to optimize the arrangement of the support member 100 according to the support requirements of different areas of the reflector 20.

[0068] In some embodiments, the support portion 120 and the reflector 20 are fixedly connected by adhesive. Through adhesive connection, the support portion 120 can provide stable support in the area in contact with the reflector 20, while defining the shape of the reflector 20, which is beneficial for the reflector 20 to form a predetermined shape within the back plate 10.

[0069] Specifically, the adhesive bonding method can form a continuous or intermittent adhesive interface between the support surface 121 and the reflective sheet 20, so that the local deformation of the reflective sheet 20 under external force can be effectively guided by the support part 120, thereby improving the uniformity and controllability of the overall reflection effect. At the same time, the adhesive layer itself has a certain degree of elasticity, which is beneficial for absorbing minor impacts or vibrations and reducing the risk of damage to the reflective sheet 20 during assembly and use.

[0070] For example, the adhesive material can be structural adhesive, pressure-sensitive adhesive or hot melt adhesive, etc. The adhesive layer can cover the entire or partial area of ​​the support surface 121, or be set as dot or strip bonding, so as to take into account both bonding strength and assembly flexibility.

[0071] In some embodiments, refer to Figure 5 and Figure 6 The fixing part 110 is slidably connected to the connecting part 130 of the support member 100, and an elastic reset key 111 is provided between the fixing part 110 and the connecting part 130. The direction in which the connecting part 130 slides relative to the fixing part 110 is a first direction. Along the first direction, the distance between the reflector 20 and the back plate 10 gradually increases or decreases, so that the support member 100 can adapt to the arc structure of the reflector 20 and generate appropriate displacement buffer when the reflector 20 is subjected to force.

[0072] Specifically, the reflector 20 is typically arc-shaped or other curved within the backplate 10, and the support member 100 experiences a component force along the horizontal or other directions when supporting the reflector 20. If the support member 100 is completely fixed to the fixing part 110, when the reflector 20 is subjected to a large external force, the local load may concentrate on the support part 120 or the connecting part 130, easily leading to excessive stress concentration or wear of the support member 100. Through a sliding connection, the support member 100 can move slightly along the first direction, thereby absorbing part of the external force and distributing the load more evenly among the support member 100, the connecting part 130, and the fixing part 110. This buffering mechanism helps reduce local stress and provides protection for the support member 100 when the reflector 20 is subjected to impact or compressive force, while also helping the reflector 20 maintain its preset shape.

[0073] For example, the sliding connection can be achieved by means of guide rail and slider, slot and insert, or flexible boss and sliding groove. The elastic reset key 111 can be an elastic tongue, spring, flexible protrusion or rubber block structure, which provides a restoring force after the support member 100 is displaced, so that the connection part 130 returns to the initial position, thereby facilitating the reflector 20 to maintain its overall shape and stability under repeated stress.

[0074] With the above structure and arrangement, the support member 100 can provide phased buffering and stress dispersion while satisfying the support and shape limitation of the reflector 20, which is beneficial to extending the service life of the support member 100 and the reflector 20, and improving the overall reliability and performance of the backlight module and display device.

[0075] In some embodiments, the support portion 120 is elastically connected to the connecting portion 130 of the support member 100, and the support portion 120 has a first state and a second state; the support portion 120 is configured to switch from the first state to the second state when the reflector 20 is deformed by an external force; wherein, when the support portion 120 is in the first state, the contact area between the support surface 121 and the reflector 20 is smaller than the contact area between the support surface 121 and the reflector 20 when it is in the second state.

[0076] When the support part 120 is in the first state, the contact area between the support surface 121 and the reflector 20 is small, which is beneficial to provide a soft and low-resistance initial contact effect. As the reflector 20 is subjected to external forces, the support part 120 deforms or rotates, and the contact area between the support surface 121 and the reflector 20 gradually increases, thereby enhancing the support effect on the reflector 20 and achieving phased support and buffering.

[0077] Specifically, the reflector 20 is typically thin and easily deformed under stress. In the initial state, the contact area between the support 120 and the reflector 20 is small, which reduces local stress during initial contact and provides a more sensitive response. When the reflector 20 is subjected to a larger external force, the support 120 rotates or undergoes slight displacement under the elastic connection, increasing the contact area between the support surface 121 and the reflector 20, thereby dispersing the load and improving the support strength. This design helps the reflector 20 maintain a stable shape under external forces, while reducing local stress concentration and improving the overall reliability of the backlight module.

[0078] For example, the elastic connection can be achieved through a flexible bending section 131, an elastic tongue, a micro-spring, or a flexible plastic sheet. The rotation or deformation of the support 120 can occur in the horizontal or vertical direction, and the specific angle and displacement range can be adjusted according to the size, thickness, and expected load of the reflector 20.

[0079] According to the second aspect of this disclosure, referring to Figure 4 and Figure 5 A backlight module is provided, including the support structure described in the above embodiments. Multiple support members 100 are arranged in two groups along the width direction of a backplate 10, and the two groups of support members 100 are symmetrically arranged with respect to the centerline of the length direction of the backplate 10. This backlight module possesses all the beneficial effects of the aforementioned support structure, which will not be elaborated further in this disclosure.

[0080] With this arrangement, the backlight module can provide fine support in different areas of the reflective sheet 20, so that the reflective sheet 20 maintains the preset shape and obtains a uniform support effect, while improving the backlight uniformity and reflection efficiency.

[0081] For example, the spacing and number of the two sets of supports 100 can be adjusted according to the width and curvature of the reflector 20 to accommodate reflectors 20 of different sizes and shapes.

[0082] According to a third aspect of this disclosure, a display device is provided, including the support structure described in the above embodiments, or including the backlight module described in the above embodiments. This display device possesses all the beneficial effects of the aforementioned support structure or backlight module, which will not be elaborated further herein.

[0083] The display device can be a television, computer monitor, laptop computer, flat panel display, or other type of flat panel display device. By employing the support structure or backlight module of this disclosure, the reflective sheet 20 in the display device can maintain a preset shape, thereby achieving flexibility in the design of the back panel 10 and diversification of the overall appearance, while also improving display uniformity and optical performance.
