[0026] As described in the background section, a display device is an electronic device that converts electronic signals (such as electrical signals, optical signals, digital signals, etc.) into directly perceptible visual information. In related technologies, a display device includes a display element, a back panel, and a bezel surrounding the display element. The bezel is fixedly connected to the back panel, and the display element is mounted on the bezel. The back panel and bezel are typically connected using adhesives; however, this connection structure is prone to loosening during long-term use.

[0027] Reference Figures 1 to 4 To address the aforementioned problems, according to one aspect of this application, an embodiment of this application provides a display device. The display device includes a back plate 100, a frame 200, a fastener 400, and a display element 500. The back plate 100 is provided with a first connection hole 121; the frame 200 is provided with a second connection hole 221; the fastener 400 passes through the first connection hole 121 and the second connection hole 221 to connect the back plate 100 and the frame 200; the display element 500 is disposed on the surface of the frame 200 away from the back plate 100; the display device has an internal space 300, which is formed by the frame 200 and the back plate 100 together, and the first connection hole 121, the second connection hole 221, and the fastener 400 are disposed within the internal space 300.

[0028] In this embodiment, the display device is one of an LCD (Liquid Crystal Display), an LED (Light-Emitting Diode), or an OLED (Organic Light-Emitting Diode). The back plate 100 is the back support member of the display device, and the frame 200 is the circumferential frame member surrounding the display element 500 of the display device. The internal space 300 refers to the closed or semi-closed space formed by the surfaces of the back plate 100 and the frame 200 that are close to each other. The fastener 400 is a fastening screw, fastening pin, or fastening rivet.

[0029] On the one hand, this application achieves a stable connection between the back panel 100 and the frame 200 by inserting fasteners 400 into the first connecting hole 121 and the second connecting hole 221. This fundamentally avoids the problem of connection failure caused by adhesive aging in adhesive connections, effectively ensuring the stability of the connection between the back panel 100 and the frame 200 and extending the service life of the display device. At the same time, compared with adhesive connections that require waiting for the adhesive to cure, the fasteners 400 also facilitate rapid assembly.

[0030] On the other hand, when the back panel 100 is assembled with the frame 200, the fastener 400 passes through the first connecting hole 121 and the second connecting hole 221, and the first connecting hole 121, the second connecting hole 221, and the fastener 400 are all located within the internal space 300. This structural design allows the fastener 400 to be hidden inside the internal space 300, effectively reducing the risk of exposure to the outside of the internal space 300, achieving the effect of hiding the fastener 400. This not only optimizes the aesthetic appearance of the display device, but also effectively reduces the risk of bumps or corrosion caused by the exposure of the first connecting hole 121, the second connecting hole 221, and the fastener 400, effectively extending the service life of the back panel 100, the frame 200, and the fastener 400.

[0031] On the other hand, the display element 500 is positioned on the surface of the bezel 200 away from the back panel 100, ensuring that the display screen of the display element 500 is unobstructed and has no blind spots, thus improving the user's viewing experience.

[0032] In addition, to enhance the connection strength and stability between the back panel 100 and the frame 200, there are multiple first connecting holes 121, which are spaced apart circumferentially along the back panel 100; there are multiple second connecting holes 221, which are spaced apart circumferentially along the frame 200, and the number of second connecting holes 221 is the same as the number of first connecting holes 121, with each of the multiple second connecting holes 221 corresponding to one of the multiple first connecting holes 121; there are multiple fasteners 400, which are the same as the number of first connecting holes 121, with each of the multiple fasteners 400 corresponding to one of the multiple first connecting holes 121.

[0033] Reference Figures 1 to 4 In one embodiment, the fastener 400 passes through the second connecting hole 221 into the first connecting hole 121.

[0034] When the back panel 100 is assembled with the frame 200, the fastener 400 is sequentially inserted into the second connecting hole 221 on the frame 200 and the first connecting hole 121 on the back panel 100. This structural design allows the fastener 400 to be inserted from the frame 200 to the back panel 100 (i.e., through the front), without the fastener 400 needing to be inserted from the side of the back panel 100 away from the frame 200 (i.e., the back). This allows the fastener 400 to be hidden inside the internal space 300, effectively reducing the risk of exposure to the outside of the internal space 300 and achieving the effect of hiding the fastener 400.

[0035] Reference Figures 2 to 4In one embodiment, the back panel 100 includes a back panel body 110 and a first connecting structure 120. The back panel body 110 has a first accommodating space 310. The first connecting structure 120 is disposed on the back panel body 110 and located within the first accommodating space 310. A first connecting hole 121 is disposed on the first connecting structure 120. The frame 200 includes a frame body 210 and a second connecting structure 220. The frame body 210 has a second accommodating space 320. The second accommodating space 320 communicates with the first accommodating space 310 and forms an internal space 300. The second connecting structure 220 is disposed on the frame body 210 and located within the second accommodating space 320. A second connecting hole 221 is disposed on the second connecting structure 220.

[0036] In this embodiment, the back panel body 110 is concave; the first connecting structure 120 is disposed on the inner wall surface of the back panel body 110 and extends toward the interior of the first accommodating space 310, and the first connecting structure 120 and the back panel body 110 are integrally formed. The frame body 210 is annular, and the second connecting structure 220 is disposed on the inner wall surface of the frame body 210 and extends toward the interior of the second accommodating space 320, and the second connecting structure 220 and the frame body 210 are integrally formed. It should be noted that the first connecting structure 120 and the back panel body 110 can also be two independent but connected components, and the second connecting structure 220 and the frame body 210 can also be two independent but connected components.

[0037] This application improves the appearance of the display device by setting the first connection hole 121 on the first connection structure 120 located in the first accommodating space 310 and the second connection hole 221 on the second connection structure 220 located in the second accommodating space 320, so that the first connection hole 121 and the second connection hole 221 are both located in the internal space 300, thereby allowing the fastener 400 to be hidden inside the internal space 300.

[0038] Reference Figure 2 and Figure 4 In one embodiment, a portion of the structure of the back panel 100 extends into the second accommodating space 320.

[0039] In this embodiment, the bezel body 210 is partially structured around the back plate 100. The back plate 100, which extends into the second accommodating space 320, works in conjunction with the bezel body 210 to not only form a radial limit, restricting the relative displacement of the back plate 100 and the bezel 200 in the horizontal direction, thereby enhancing the connection stability between the two; at the same time, this embedded structure can also reduce the overall size of the display device, thereby enabling a compact design of the display device.

[0040] Reference Figure 2 and Figure 4In one embodiment, the first connecting structure 120 abuts against the second connecting structure 220.

[0041] In this embodiment, the portion of the first connecting structure 120 located near the back panel body 110 at the first connecting hole 121 and the portion of the second connecting structure 220 located near the frame body 210 at the second connecting hole 221 are kept in close contact. The first connecting structure 120 and the second connecting structure 220 are tightly fitted together, forming a surface contact fit. The locking force of the fastener 400 further enhances the connection stability and reliability between the back panel 100 and the frame 200, and also helps to reduce the overall size of the display device.

[0042] Reference Figures 2 to 4 In one embodiment, the first connecting hole 121 is a threaded hole, and the second connecting hole 221 is a through hole; the fastener 400 includes a fastening body 410 and a limiting structure 420. The fastening body 410 passes through the second connecting hole 221 into the first connecting hole 121 and is threadedly engaged with the first connecting hole 121; the limiting structure 420 is disposed on the fastening body 410, and the hole wall of the second connecting hole 221 is used to prevent the limiting structure 420 from moving toward the first connecting hole 121.

[0043] In this embodiment, the fastening body 410 is a threaded fastening rod, and the limiting structure 420 is a limiting head or a limiting cap. The limiting structure 420 is coaxially arranged with the fastening body 410 and is an integrally formed part, forming a screw. It should be noted that the limiting structure 420 and the fastening body 410 can also be two independent but interconnected components. The second connecting hole 221 can prevent the limiting structure 420 from moving toward the first connecting hole 121 by forming a stepped hole with the first connecting hole 121, providing a radially inwardly extending protrusion or rib on its own hole wall, or providing threads on its own hole wall.

[0044] In one specific embodiment, the first connecting hole 121 is a threaded hole, and the second connecting hole 221 is a smooth hole; in another specific embodiment, both the first connecting hole 121 and the second connecting hole 221 are threaded holes. It should be noted that when the fastener 400 is a fastening pin or a fastening rivet, both the first connecting hole 121 and the second connecting hole 221 can be smooth holes.

[0045] The fastening body 410 is threaded into the first connecting hole 121 to form a detachable and high-strength mechanical connection, which further ensures the stability of the long-term connection between the back plate 100 and the frame 200 and the ease of disassembly. At the same time, the limiting structure 420 and the hole wall of the second connecting hole 221 cooperate to quickly position the fastening body 410 in the installation position, effectively improving assembly efficiency and reducing operation difficulty.

[0046] Reference Figures 2 to 4 In one embodiment, the second connecting hole 221 includes a first hole segment 2211 and a second hole segment 2212 that are connected to each other. The second hole segment 2212 is located on the side of the first hole segment 2211 away from the first connecting hole 121 and covers the first hole segment 2211. The fastening body 410 is inserted into the first hole segment 2211, and the limiting structure 420 is inserted into the second hole segment 2212. The hole wall of the second hole segment 2212 is used to prevent the limiting structure 420 from moving toward the first connecting hole 121.

[0047] In this embodiment, the second hole segment 2212 is coaxially arranged with the first hole segment 2211, and the diameter of the second hole segment 2212 is larger than the diameter of the first hole segment 2211.

[0048] When assembling the back panel 100 and the frame 200, the fastening body 410 is quickly inserted through the first hole section 2211 to the first connecting hole 121, and the limiting structure 420 is simultaneously fitted and inserted into the second hole section 2212. No additional alignment tools are required throughout the process. At the same time, the second hole section 2212 forms a blocking effect on the limiting structure 420 through the hole wall. This blocking effect can serve as a direct feedback on the proper assembly. The operator can confirm the installation status by sensing the contact resistance between the limiting structure 420 and the hole wall of the second hole section 2212, which reduces the difficulty of operation.

[0049] Reference Figure 2 and Figure 4 In one embodiment, the surface of the limiting structure 420 away from the fastening body 410 is the first surface 421, and the surface of the frame 200 with the second hole segment 2212 is the second surface 222. The first surface 421 is located inside the second hole segment 2212 or is flush with the second surface 222.

[0050] In this embodiment, the second hole segment 2212 is disposed on the surface of the second connecting structure 220 away from the first connecting structure 120, and the surface of the second connecting structure 220 away from the first connecting structure 120 is the second surface 222; the fastener 400 is a countersunk screw.

[0051] In one embodiment, the first surface 421 is located within the second hole segment 2212; in another embodiment, the first surface 421 is flush with the second surface 222.

[0052] The first surface 421 is located inside the second hole segment 2212 or flush with the second surface 222, effectively avoiding the limiting structure 420 from being exposed on the surface of the frame 200 and forming a protrusion. This not only keeps the appearance of the frame 200 flat and clean, but also reduces the risk of fastener 400 interfering with other components in the display device.

[0053] Reference Figures 2 to 4In one embodiment, one of the back plate 100 and the frame 200 is provided with a guide protrusion 130 and the other is provided with a guide groove 230, with the guide protrusion 130 inserted into the guide groove 230.

[0054] In this embodiment, the guide protrusion 130 is a guide protrusion formed by bending. The guide protrusion 130 is located between the back plate body 110 and the first connecting structure 120 and is part of the back plate 100. The guide groove 230 is disposed on the second connecting structure 220. It should be noted that the guide protrusion 130 can also be disposed on the frame 200 and the guide groove 230 can be disposed on the back plate 100.

[0055] The coordinated guide protrusion 130 and guide groove 230 can form a guide and position through a plug-in engagement, quickly guiding the back plate 100 to dock with the frame 200, and can also form a reliable limit, effectively restricting the relative shaking between the back plate 100 and the frame 200.

[0056] In addition, there are multiple guide protrusions 130, which are spaced apart circumferentially along the back plate 100; the number of guide grooves 230 is the same as the number of guide protrusions 130, and the multiple guide grooves 230 are respectively arranged in a one-to-one correspondence with the multiple guide protrusions 130.

[0057] Reference Figure 1 and Figure 2 In one embodiment, the surface of the bezel body 210 away from the back panel 100 is a third surface 211, located on the side of the second surface 222 away from the back panel 100. An adhesive structure 510 (such as double-sided tape or optical adhesive) is provided on the second surface 222. The display element 500 is mounted to the second surface 222 via the adhesive structure 510, so that the bezel body 210 encloses the display element 500, thereby providing circumferential protection for the display element 500. Specifically, the display element 500 includes a display body and tempered glass. The display body includes a touch structure and a display structure. The display body is mounted on the second surface 222, and the tempered glass is disposed on the surface of the display body away from the second connecting structure 220, completely covering the display body.

[0058] Reference Figure 1 and Figure 2 In one embodiment, the display device further includes a reflector 600, a diffuser 700, and an optical element 800, wherein the reflector 600 is located within the internal space 300 and disposed on the back plate 100; the diffuser 700 is located within the internal space 300 and disposed on the surface of the reflector 600 near the display element 500; and the optical element 800 is located within the internal space 300 and disposed on the surface of the diffuser 700 near the display element 500.

[0059] In this embodiment, the reflector 600, diffuser 700, and optical element 800 are stacked along the direction from the back plate 100 to the frame 200. The reflector 600 is a reflective sheet, and part of the structure of the reflector 600 is fixedly installed to the inner wall surface of the back plate body 110 by adhesive bonding. Another part of the structure of the reflector 600 is fixedly installed to the surface of the first connecting structure 120 near the second connecting structure 220 by adhesive bonding. There is a placement gap 900 between the part of the first connecting structure 120 located away from the back plate body 110 at the first connecting hole 121 and the part of the second connecting structure 220 located away from the frame body 210 at the second connecting hole 221. The diffuser 700 is a diffuser sheet, which is placed on the surface of the reflector 600 away from the first connecting structure 120 and located within the placement gap 900. The optical element 800 is an optical film, which is placed on the surface of the diffuser 700 away from the diffuser 700 and located within the placement gap 900.

[0060] The reflector 600, diffuser 700, and optical component 800 work together to form a complete optical transmission path. The reflector 600 reflects light diverging towards the back panel 100 to the diffuser 700, reducing light loss. The diffuser 700 evenly diffuses concentrated light, reducing the risk of bright spots and dark areas. The optical component 800 further optimizes the polarization direction of light and improves light transmission efficiency. The three components work together to project light evenly and efficiently onto the display component 500, improving the brightness uniformity, clarity, and color reproduction of the displayed image, and enhancing the user's viewing experience.

[0061] Reference Figure 2 and Figure 5 In one embodiment, a limiting protrusion 140 is provided on the back plate 100, and at least one of the reflector 600, diffuser 700 and optical element 800 is provided with a limiting hole 1000, with the limiting protrusion 140 passing through the limiting hole 1000.

[0062] In this embodiment, the limiting protrusion 140 is a limiting protrusion, which is disposed on the first connecting structure 120 and is integrally formed with the first connecting structure 120. A limiting hole 1000 is provided on the edge of the diffuser 700. This limiting hole 1000 is a notch design, which achieves the limiting of the diffuser 700 without increasing its overall size. A connecting protrusion 810 is provided on the edge of the optical component 800. The connecting protrusion 810 is integrally formed with the optical component 800, and the limiting hole 1000 is disposed on the connecting protrusion 810. It should be noted that the limiting hole 1000 can also be provided on the reflector 600.

[0063] The cooperating limiting protrusion 140 and limiting hole 1000 can form a mechanical limit, effectively restricting the component with limiting hole 1000 in the optical assembly from shaking randomly within the internal space 300, ensuring the assembly stability of the optical assembly; it also has a guiding and positioning function, guiding the component with limiting hole 1000 in the optical assembly to be quickly installed in place, simplifying the assembly process.

[0064] In addition, to enhance the limiting effect, there are multiple limiting protrusions 140, which are spaced apart circumferentially along the back plate 100; there are multiple limiting holes 1000 on the diffuser 700, which are spaced apart circumferentially along the diffuser 700, and the number of limiting holes 1000 is the same as the number of limiting protrusions 140, with each limiting hole 1000 corresponding to one of the multiple limiting protrusions 140; there are multiple limiting holes 1000 on the optical component 800, which are spaced apart circumferentially along the optical component 800, and the number of limiting holes 1000 is the same as the number of limiting protrusions 140, with each limiting hole 1000 corresponding to one of the multiple limiting protrusions 140.

[0065] Reference Figure 2 In one embodiment, a cushioning foam 1100 is sandwiched between the optical component 800 and the second connecting structure 220 to ensure the assembly stability of the optical component 800 and the optical assembly.

[0066] In summary, the display device provided in this embodiment has at least the following beneficial technical effects: On the one hand, by inserting fasteners 400 into the first connecting hole 121 and the second connecting hole 221, this application achieves a stable connection between the back panel 100 and the frame 200, fundamentally avoiding the problem of connection failure caused by adhesive aging in adhesive connections, effectively ensuring the stability of the connection between the back panel 100 and the frame 200, and extending the service life of the display device. At the same time, compared to adhesive connections that require waiting for the adhesive to cure, the fasteners 400 also facilitate rapid assembly.

[0067] On the other hand, when the back panel 100 is assembled with the frame 200, the fastener 400 is sequentially inserted into the second connecting hole 221 on the frame 200 and the first connecting hole 121 on the back panel 100, and the first connecting hole 121, the second connecting hole 221 and the fastener 400 are all located within the internal space 300. This structural design allows the fastener 400 to be inserted from the frame 200 to the back panel 100 (i.e., through the front), without the fastener 400 needing to be inserted from the side of the back panel 100 away from the frame 200 (i.e., the back), thus allowing the fastener 400 to be hidden inside the internal space 300, effectively reducing the risk of exposure to the outside of the internal space 300, achieving the effect of hiding the fastener 400. This not only optimizes the aesthetic appearance of the display device, but also effectively reduces the risk of bumps or corrosion caused by the exposure of the first connecting hole 121, the second connecting hole 221 and the fastener 400, effectively extending the service life of the back panel 100, the frame 200 and the fastener 400.

[0068] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. It should be noted that, for those skilled in the art, several equivalent obvious modifications and / or equivalent substitutions can be made without departing from the technical principles of this application, and these obvious modifications and / or equivalent substitutions should also be considered within the scope of protection of this application.
