Description

Technical Field

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

[0002] In existing display devices, backlight modules typically consist of a backplate, light-emitting elements, a support assembly, and a diffuser plate. In direct-lit backlight modules, the diffuser plate is suspended above the backplate. To suppress its bending deformation under its own weight or external forces, a support assembly must be arranged between the backplate and the diffuser plate. At the same time, this support assembly is used to raise the required light mixing distance between the backplate and the diffuser plate.

[0003] Currently, the industry commonly uses thin-film support components. However, the tips of the thin film are slender and easily bent or even broken; if the thickness is simply increased to improve strength, the projected area of ​​the support component on the diffuser plate will increase, which will cast obvious shadows in the image and affect the optical quality. Utility Model Content

[0004] This application provides a support component, a backlight module, and a display device to solve the problem that common support components mainly adopt a sheet structure, which is prone to deformation or breakage due to its thinness and slender tip. If the sheet support is thickened, its projected area on the diffuser plate will increase, resulting in obvious shadows.

[0005] In a first aspect, this application provides a support component applied to a backlight module, the backlight module including a backplate and a diffuser plate, the support component being located between the backplate and the diffuser plate, comprising: The support member has a buffer hole, one end of the support member is used to connect to the back plate, and the other end of the support member is used to abut against the diffuser plate; A buffer member is connected to the support member, and the buffer member is located within the buffer hole; wherein, when the diffuser plate is subjected to pressure, the support member and the buffer member can undergo elastic deformation, and the length of the support member decreases in a first direction.

[0006] Optionally, the buffer has two parallel reinforcing members and two oppositely arranged bent members. The two reinforcing members are spaced apart along a first direction, and one reinforcing member and one bent member are connected end to end to form a concave hexagonal unit.

[0007] Optionally, the buffer includes a plurality of concave hexagonal units spaced apart along a first direction, with adjacent concave hexagonal units connected by a reinforcing member.

[0008] Optionally, the buffer further includes a plurality of concave hexagonal units spaced apart along the back plate to the diffuser plate, and a connector is provided between two adjacent concave hexagonal units, the connector connecting the middle of the bending part of two adjacent concave hexagonal units.

[0009] Optionally, the bending member has two bent segments arranged at an angle, and the two bent segments are respectively arranged at an angle to one of the reinforcing members.

[0010] Optionally, the support member has an axisymmetric structure, and the buffer hole is located at the axis of symmetry of the support member and is arranged symmetrically with respect to the axis of symmetry.

[0011] Optionally, the support member has multiple buffer holes, each buffer hole being spaced apart from the support member. The support assembly includes multiple buffer members, each buffer member being connected to the support member, and each buffer member accommodating a buffer hole.

[0012] Optionally, the support member and the buffer member are integrally formed.

[0013] Optionally, the support and the buffer are made of polymethyl methacrylate (PMMA) or polycarbonate (PC).

[0014] Secondly, this application also provides a backlight module, including: Back panel; A diffuser plate, the diffuser plate being located on one side of the back plate; A light-emitting element, which is connected to the back plate and is located between the back plate and the diffuser plate; Multiple support components provided in the first aspect of this application are located between the light-emitting substrate and the optical film group, with one end of the support member connected to the back plate and the other end of the support member abutting the diffuser plate.

[0015] Thirdly, this application also provides a display device, including the backlight module provided in the second aspect of this application.

[0016] The technical solutions provided in this application have the following advantages compared with the prior art: The support member in this embodiment can be integrally injection molded from polymethyl methacrylate (PMMA) or polycarbonate (PC). The buffer hole extends through the support member along its thickness direction. The buffer member can be made of the same material as the support member or silicone, and is press-fitted into the buffer hole. Specifically, the buffer member has a negative Poisson's ratio honeycomb structure. When the diffuser plate is compressed, the support member is compressed as a whole, and the force is transmitted to the buffer member through the inner wall of the buffer hole. Because the buffer member has a negative Poisson's ratio honeycomb structure, when pressure is applied to the top of the buffer member, the length of the support member shortens along the first direction perpendicular to the pressure, achieving elastic yielding under pressure. Since the support member and the buffer hole form an integral elastic structure, when the diffuser plate is subjected to gravity or external impact, the support member can undergo controllable compression in the first direction, and the negative Poisson's ratio honeycomb structure of the internal buffer member contracts, pulling the sidewall of the support member inward. This effect effectively suppresses the initial lateral deformation that causes bending deformation and enhances the bending resistance of the support member. Meanwhile, a negative Poisson's ratio honeycomb structure is integrated into the buffer hole in the center of the support, which reduces the light-blocking area of ​​the material and can effectively reduce the shadow of the support on the diffuser plate.

[0025] To address the common problem that sheet-like structures in common support components are prone to deformation or breakage due to their thinness and slender tips, and that thickening the sheet-like support 1 would increase its projected area on the diffuser plate 4, resulting in noticeable shadows, this application provides a support component with a buffer hole 1a inside the support 1. A buffer 2 with a negative Poisson's ratio honeycomb structure is placed inside the buffer hole 1a. By utilizing the characteristic of the negative Poisson's ratio honeycomb structure buffer 2 to contract under pressure, the support 1 achieves elastic displacement under pressure. The lateral contraction of the negative Poisson's ratio honeycomb structure effectively improves the structural stability and optical performance of the support 1, balancing mechanical strength and image quality.

[0026] Figures 1 to 6 A support component provided in this application embodiment is applied to a backlight module. The backlight module includes a back plate 3 and a diffuser plate 4. The support component is located between the back plate 3 and the diffuser plate 4 and includes: a support member 1 and a buffer member 2. The support member 1 has a buffer hole 1a. One end of the support member 1 is used to connect to the back plate 3, and the other end of the support member 1 is used to abut against the diffuser plate 4. The buffer member 2 is connected to the support member 1 and is located within the buffer hole 1a. When the diffuser plate 4 is subjected to pressure, the support member 1 and the buffer member 2 can undergo elastic deformation, and the length of the support member 1 decreases in a first direction.

[0027] In this embodiment, the support member 1 is a triangular or trapezoidal plate-shaped structure made of high-transmittance PMMA or PC. A buffer hole 1a is formed through the center along the thickness direction. The shape of the buffer hole 1a is not limited; it can be the same shape as the outer shape or other symmetrical structures to ensure uniform stress. The cross-sectional area of ​​the buffer hole 1a accounts for approximately 30% of the total cross-sectional area of ​​the support member 1, ensuring sufficient overall strength. The buffer member 2 is a negative Poisson's ratio concave hexagonal honeycomb structure made of the same material as the support member 1. The outer contour of the buffer member 2 is interference-fitted with the buffer hole 1a, and the end face is flush. The first direction is the width direction of the support member 1. The apex angle of the triangular support member 1 can be set to 30° to 45°. The buffer hole 1a is also triangular. The outer wall of the buffer member 2 abuts against the inner wall of the buffer hole 1a. When the support member 1 is compressed, the concave hexagonal sidewalls fold inward, causing the sidewalls of the triangular support member 1 to retract synchronously along its width direction, avoiding the problem of outward protrusion in the middle. In some embodiments, the buffer hole 1a can be set as a circle or a rectangle, and the buffer 2 can also be set as a circle or a rectangle. This common shape is easy to process and can achieve the above-mentioned technical effects.

[0028] In this application, when the support member 1 is under pressure, the buffer member 2 contracts laterally to tighten the sidewall, suppressing the problem of bulging of the traditional support member 1. Due to the contraction characteristics of the structure, the bending stiffness of the support member 1 is increased when compressed, avoiding the problem of the support member 1 breaking. The through holes and honeycomb cavities greatly reduce the solid light-blocking area. Combined with the high light-transmitting material, the projected shadow is broken down into fine dots that are almost invisible to the naked eye, which can effectively reduce the shadow of the support member 1 on the diffuser plate 4.

[0029] Please see Figures 1 to 3 In order to enable the buffer 2 to contract better when compressed, the buffer 2 has two parallel reinforcing members 21 and two oppositely arranged bending members 22. The two reinforcing members 21 are spaced apart along the first direction, and one reinforcing member 21 and one bending member 22 are connected end to end to form a concave hexagonal unit 23.

[0030] In one embodiment, the buffer 2 is a single-piece concave hexagonal negative Poisson's ratio honeycomb, which is formed by ultrasonic welding or integral injection molding of two parallel thin sheet reinforcements 21 arranged at intervals along the first direction and two symmetrical concave bending members 22. The reinforcements 21 are 0.1-0.3 mm thick and have the same width as the support 1. The bending members 22 are 0.1-0.3 mm thick. The four of them form a closed concave hexagonal unit 23. The buffer 2 can be a single concave hexagonal unit 23 or a whole buffer 2 formed by a continuous array of several units along the transverse and longitudinal directions. The shape of the buffer 2 is consistent with the buffer hole 1a. After interference pressing, the bending members 22 are suspended above the hole wall of the buffer hole 1a. The top of the support 1 abuts against the diffuser plate 4 and the bottom abuts against the back plate 3. The reinforcing member 21 and the bending member 22 can be made of the same high-transmittance PC material. After injection molding, the bending member 22 is laser-trimmed to ensure the concave radius of the bending member 22. When under pressure, the bending member 22 folds inward first, causing the reinforcing members 21 on both sides to move closer together, thus achieving lateral contraction.

[0031] In the embodiments of this application, the two reinforcing members 21 serve as bearing surfaces, uniformly transmitting the pressure of the diffuser plate 4 to the bending member 22. When the concave section of the bending member 22 is under pressure, it quickly folds inward, causing the buffer member 2 to contract laterally along the width direction of the support member 1, preventing the support member 1 from bulging outward and encroaching on the light mixing space. The density of the closed concave hexagonal unit 23 increases during the folding process, and the stiffness gradually increases, providing a smooth buffer and eliminating the risk of sudden collapse of traditional positive Poisson's ratio foam. The reinforcing members 21 and the bending member 22 can be made of the same material or a combination of different materials, taking into account both light transmittance and flexibility, reducing the light-blocking area, and reducing the brightness difference between shadows in the image to less than 1%. An array layout can be set to achieve better shrinkage effect, the side wall of the support member 1 is subjected to uniform force, the bending resistance is improved, and the long-term reliability and optical quality of the backlight module are ensured.

[0032] Please see Figure 2 and Figure 3 To further improve the shrinkage effect of the support member 1, the buffer member 2 includes a plurality of concave hexagonal units 23 spaced apart along the first direction, and adjacent two concave hexagonal units 23 are connected by a reinforcing member 21.

[0033] In this embodiment, the buffer 2 is formed by multiple concave hexagonal units 23 arranged at intervals along the first direction (the width direction of the support 1) to form a transverse chain. Adjacent units share a transverse thin sheet reinforcement 21, which also serves as the side of the left and right units. It is formed into a continuous concave honeycomb strip by integral injection molding or laser cutting. The shape of the entire honeycomb strip matches the buffer hole 1a. After interference pressing, the reinforcements 21 in the middle move closer to each other under pressure. The units arranged at intervals in the width direction are connected in series through the reinforcements 21. Under pressure, each unit shrinks synchronously in the lateral direction, and the overall width reduction is superimposed, which significantly improves the shrinkage rate of the support 1 in the width direction and avoids one-sided outward bulging that encroaches on the light mixing space. The reinforcement 21 serves as a force transmission hub, which makes the folding deformation evenly distributed and prevents local stress concentration. The sidewall of the support 1 is pulled inward and the bending resistance is enhanced. The flexible or reflective reinforcement 21 takes into account both buffering and supplementary lighting, reducing the difference in brightness between shadows in the picture and taking into account both mechanical performance and optical quality.

[0034] Please see Figure 2 and Figure 3 In order to allow the force on the diffuser plate 4 to be absorbed more by the buffer member 2, the buffer member 2 also includes a plurality of concave hexagonal units 23 spaced apart along the back plate 3 to the diffuser plate 4. A connector 24 is provided between two adjacent concave hexagonal units 23, and the connector 24 connects the middle part of the bending part 22 of two adjacent concave hexagonal units 23.

[0035] In one embodiment, the buffer 2 has multiple layers of concave hexagonal units 23 stacked in the pressure direction from the diffuser plate 4 to the back plate 3. Thin sheet-like connectors 24 are provided between the concave vertices of the middle of the adjacent layers corresponding to the bending parts 22. The connectors 24 and the bending parts 22 are integrally injection molded or subsequently hot-melted into a "V"-shaped force transmission chain. When the upper edge of the buffer 2 is compressed, the connectors 24 directly introduce the load into the weakest middle section of each layer of bending parts 22, causing progressive folding. The connectors 24 directly transmit the pressure of the diffuser plate 4 to the middle of each layer of bending parts 22. Folding occurs first at the weakest point, and the multiple units retract in sequence. The load is absorbed step by step, preventing the reinforcing member 21 from being damaged by high pressure alone or damaging the diffuser plate 4. Flexible or staggered connections provide progressive stiffness and micro-slippage, and the impact energy is dissipated layer by layer. The sidewall of the support member 1 is subjected to uniform force, and the bending resistance is significantly improved. The multiple layers shrink laterally without bulging, and the light mixing space is not affected. With the help of high light transmittance materials, the difference in brightness between shadows in the picture is further reduced.

[0036] Please see Figures 1 to 3 In order to ensure that the two sides of the buffer 2 contract evenly when subjected to pressure, the bending member 22 has two bending sections 221 set at an angle, and the two bending sections 221 are respectively set at an angle θ with a reinforcing member 21.

[0037] In one embodiment of this application, the bending member 22 consists of two symmetrical bending segments 221. The two bending segments 221 are inclined inward from the end of the reinforcing member 21 and intersect at an included angle, forming a concave "∧" shaped skeleton. The two bending segments 221 and their respective connected reinforcing members 21 have the same included angle, ensuring that the two side walls fold inward synchronously under pressure. For example, the included angle θ between the bending segment 221 and the reinforcing member 21 is 45°. The relationship between the length L of the reinforcing member 21 and the length h of the bending segment 221 is: L=2h. The material is high-transparency PC, integrally injection molded, and the two side walls contract inward simultaneously under pressure, avoiding collapse on one side first. The wall thickness of the bending segment 221 can be set to be slightly smaller than that of the reinforcing member 21, and the folding starting point is controlled in the middle of the bending segment 221, resulting in a larger contraction stroke.

[0038] The symmetrical angle design ensures that the two bending sections 221 generate equal lateral forces when under pressure, and the buffer 2 contracts synchronously from left to right, preventing the side wall of the support 1 from bulging outward and sinking inward due to uneven force, thus stabilizing the folding trajectory. The folding start point and angle can be finely adjusted by the angle and wall thickness to achieve a stiffness gradient, so that the impact energy is evenly dissipated and the bending resistance of the support 1 is enhanced. The soft and hard composite solution eliminates folding noise and maintains a low shading area by using high light transmittance material.

[0039] Please see Figures 4 to 5 In order to prevent the two sides of the support member 1 from shrinking evenly when subjected to pressure, the support member 1 has an axisymmetric structure. The buffer hole 1a is located at the axis of symmetry 1b of the support member 1 and is arranged symmetrically with respect to the axis of symmetry 1b.

[0040] In one embodiment, the support member 1 is designed as an axisymmetric thin plate that is mirrored about the central axis of symmetry 1b. Its shape is an isosceles trapezoid or isosceles triangle. A buffer hole 1a extends along the thickness direction and is centrally located in the region of the axis of symmetry 1b. The hole shape is also a symmetrical polygon or elongated groove, ensuring that the cross-sectional areas of the two side walls are equal. The negative Poisson's ratio honeycomb buffer member 2 has the same shape as the buffer hole 1a and is press-fitted in. The honeycomb itself is mirrored about the axis of symmetry 1b, allowing the folding force to be evenly transmitted to both side walls. The axisymmetric support member 1 and the centrally located symmetrical buffer hole 1a ensure that the load acts on the central axis, and the forces on both side walls are equal, avoiding eccentric bending. The lateral contraction caused by folding of the buffer member 2 is evenly distributed along the axis of symmetry 1b, with both sides contracting inwards synchronously, preventing unilateral bulging from encroaching on the light mixing space and ensuring uniform screen brightness.

[0041] Please see Figure 5 In order to further improve the shrinkage effect of the entire support member 1, the support member 1 is provided with multiple buffer holes 1a, and each buffer hole 1a is spaced apart on the support member 1. The support assembly includes multiple buffer members 2, each buffer member 2 is connected to the support member 1, and each buffer member 2 is limited to a buffer hole 1a.

[0042] In this embodiment, the support member 1 is a thin plate with multiple buffer holes 1a spaced apart along its width or circumference. The hole shape can be circular, elliptical, or other polygonal. A negative Poisson's ratio honeycomb buffer member 2 is press-fitted into each buffer hole 1a. The shape of the buffer member 2 is consistent with that of the buffer hole 1a, forming a modular array of "one hole and one buffer member 2". These buffer holes 1a and buffer members 2 are symmetrically arranged along the axis of symmetry 1b of the support member 1, ensuring that both sides of the support member 1 can shrink synchronously and uniformly after being compressed. The multi-hole distributed layout decomposes the original overall bending deformation into several local miniaturizations, significantly improving the shrinkage rate of the support member 1 in the width direction and avoiding unilateral bulging. Each buffer member 2 responds independently, and local overload failure does not affect other units, resulting in high damage tolerance. The array perforation greatly reduces the light-blocking area, and the shadows on the screen change from concentrated patches to fine dots, which are almost invisible to the naked eye, balancing high shrinkage, high reliability, and optical quality.

[0043] Support component 1 and buffer component 2 are made of the same high-transmittance PMMA or PC material, and are integrally injection molded into a non-detachable single structure. The mold uses a fusible core or a slider side-pull mechanism to directly form multiple concave hexagonal honeycomb buffer holes 1a within the thin wall of support component 1. The honeycomb wall is seamlessly connected to the side wall of support component 1, eliminating the need for subsequent assembly. The integral molding eliminates the tolerance of separate assembly, and there is no risk of slippage at the interface between buffer component 2 and support component 1. Even after long-term vibration, it still maintains synchronous contraction, resulting in high structural reliability. The elimination of secondary insertion or welding processes shortens the production line cycle time, improves material utilization, and reduces unit cost. The seamless connection avoids interface reflection, further reduces the light-blocking area, and makes optical shadows negligible. The soft and hard dual-injection or micro-foaming solution allows for local adjustment of stiffness, enabling controllable folding start and stop and eliminating abnormal noise.

[0044] Secondly, please refer to Figure 6 This application also provides a backlight module, including a back plate 3, a diffuser plate 4, a light-emitting element 5, and a plurality of support components; the diffuser plate 4 is located on one side of the back plate 3; the light-emitting element 5 is connected to the back plate 3 and is located between the back plate 3 and the diffuser plate 4; the support components are located between the light-emitting substrate and the optical film group, one end of the support component 1 is connected to the back plate 3, and the other end of the support component 1 abuts against the diffuser plate 4.

[0045] In this embodiment, the back plate 3 is stamped to form a reflective cavity, with multiple LED light-emitting elements 5 evenly distributed at the bottom of the cavity; the diffuser plate 4 is suspended above the cavity opening, and the distance between the two constitutes the light mixing distance; the support assembly is arranged in the space between adjacent LEDs, and the bottom end of the support member 1 is provided with a rotating buckle or hot-melt column, which is inserted into the corresponding hole of the back plate 3 and locked; the top end of the support member 1 abuts against the lower surface of the diffuser plate 4 to achieve point contact support; a buffer hole 1a is opened in the middle of the support member 1, and a negative Poisson's ratio honeycomb buffer member 2 is embedded inside, which can be integrally injection molded with the support member 1 of the same material or assembled separately with interference fit. The support member 1 is an axisymmetric thin plate, and the three buffer holes 1a are evenly arranged along the width direction, corresponding to three honeycomb units, which shrink synchronously when compressed, avoiding uneven local shrinkage of the diffuser plate 4. The support component is located between the light-emitting element 5 and the diffuser plate 4, occupying the LED gap without blocking the main beam; the negative Poisson's ratio honeycomb shrinks laterally when the diffuser plate 4 is heated or loaded, causing the side wall of the support component 1 to retract inward, preventing outward bulging from encroaching on the light mixing space and ensuring display brightness; the snap-on or hot-melt fixing eliminates the need for screws, the back of the back plate 3 is flat, and the assembly efficiency is improved.

[0046] Thirdly, please refer to Figure 6 This application also provides a display device, including the backlight module provided in the second aspect of this application. The support component of the backlight module adopts a structure where the negative Poisson's ratio honeycomb buffer 2 and the support 1 are integrated or separate, forming multi-point elastic support between the LED light-emitting element 5 and the diffuser plate 4. This can significantly suppress the sagging and thermal expansion deformation of the diffuser plate 4, while reducing support shadows and improving brightness uniformity. The display panel is attached to the top of the diffuser plate 4 and fixed to the back plate 3 through the frame to form a complete display module. The display device directly adopts the advantages of high shrinkage, low shadows, and impact resistance of the backlight module, making the whole device thinner and the bezel narrower, while reducing display unevenness or accidental touches caused by support failure. The modular support component is compatible with panels of different sizes and resolutions, eliminating the need to redesign the back plate 3 structure and reducing the overall development cost. Long-term reliability tests show that the support 1 and the honeycomb are not loose or broken, and the screen brightness uniformity remains greater than 85%, taking into account the requirements of thinness, high image quality, and durability of terminal products.
