[0016] The beneficial effects of the display device provided in this application are as follows: In this application, the protective panel is first initially positioned by being erected on the mounting component, forming a basis for mechanical contact; then, a pressing component applies continuous pressure to the protective panel, ensuring that the protective panel is securely installed on the mounting component. The pressing component is far less affected by ambient temperature and vibration than adhesive, and can apply stable pressure to the protective panel over a long period, effectively improving the stability of the protective panel installed on the mounting component; at the same time, it eliminates the need for an adhesive curing process, shortening assembly time and improving assembly efficiency. Furthermore, this structural design, which involves erecting the protective panel on the mounting component and using the pressing component to press the protective panel against the mounting component, avoids the need for a mid-frame to support and install the protective panel.

[0045] As described in the background section, a display device is an electronic device capable of converting electrical signals, optical signals, or other forms of information into visual information that can be directly perceived by humans. In related technologies, a display device includes a display element, a mounting element, and a protective panel. The display element is mounted on the mounting element, and the protective panel is mounted on the mounting element and covers the display element. However, the connection between the protective panel and the mounting element often relies on adhesive bonding. During long-term use, the adhesive is prone to weakening due to changes in ambient temperature, vibration, impact, or aging, causing gaps or even detachment between the protective panel and the mounting element.

[0046] 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, which includes a display element 100, a protective panel 200, a mounting member 300, and a pressing member 400. The display element 100 is used to display visual information; the protective panel 200 is disposed on one side of the display element 100 and is used to protect the display element 100; the mounting member 300 overlaps with the protective panel 200 to mount the protective panel 200 on the mounting member 300; the pressing member 400 is mounted on the mounting member 300 and abuts against the protective panel 200 to press the protective panel 200 against the mounting member 300.

[0047] In this embodiment, the display element 100 is a liquid crystal display module. It is understood that the display element 100 can also be a light-emitting diode (LED) display module or an organic light-emitting diode (OLED) display module. The protective panel 200 is a tempered glass panel, having a front and a back side arranged opposite each other along its thickness direction. The display element 100 is fixedly adhesively attached to the back side of the protective panel 200. It is understood that the protective panel 200 can also be a transparent plastic panel or a composite panel. The mounting element 300 is an annular profile. It is understood that the mounting element 300 can also be a mounting frame. The mounting element 300 can overlap with the protective panel 200 through planar overlap, vertical overlap, or nested overlap. The pressing element 400 can be a pressing strip or pressing block fixed to the mounting element 300 by connecting screws, or a pressing strip or pressing block magnetically fixed to the mounting element 300 by a magnetic structure.

[0048] In this application, the protective panel 200 is first initially positioned on the mounting component 300, forming the basis for mechanical contact. Then, the pressing component 400 applies continuous pressure to the protective panel 200, ensuring its stable installation on the mounting component 300. The pressing component 400 is far less affected by ambient temperature and vibration than adhesive, providing a stable pressure to the protective panel 200 over a long period, effectively improving the stability of the protective panel 200 on the mounting component 300. Furthermore, it eliminates the need for an adhesive curing process, shortening assembly time and improving assembly efficiency. In addition, by placing the protective panel 200 on the mounting component 300 and pressing it against it with the pressing component 400, this structural design avoids the need for a mid-frame to support and install the protective panel 200. This not only reduces manufacturing costs but also prevents the mounting component 300 from needing to expand outwards due to the presence of a mid-frame, effectively reducing the size of the display device and the black border, thus facilitating a narrow-bezel design for the display device.

[0049] Reference Figure 1 and Figure 2 In one embodiment, the mounting member 300 is disposed around the protective panel 200 and has a first mounting surface 310; the first mounting surface 310 is provided with a mounting groove 311, and a portion of the structure of the protective panel 200 is embedded in the mounting groove 311.

[0050] In this embodiment, the mounting member 300 has an enclosing space, and the protective panel 200 is disposed within the enclosing space. The mounting member 300 includes a plurality of mounting strips connected end to end in sequence, with a corner provided between two adjacent mounting strips. The corner is detachably connected to the two mounting strips so that the protective panel 200 can be inserted into the mounting groove 311. The first mounting surface 310 is the surface of the mounting member 300 facing the protective panel 200. It can be understood that the protective panel 200 can also be mounted on the outer surface of the mounting member 300.

[0051] The mounting groove 311 not only physically limits the protective panel 200, thus restricting its movement on the mounting member 300 and effectively improving its stability, but also increases the contact area between the protective panel 200 and the mounting member 300. This design, where part of the protective panel 200 is embedded in the mounting groove 311, makes the load on the protective panel 200 more even and enhances its load-bearing capacity. Furthermore, it effectively reduces the overall size of the display device.

[0052] Reference Figure 1 and Figure 2In one embodiment, the mounting member 300 further has a display surface 320 disposed adjacent to the first mounting surface 310, the display surface 320 being provided with a display opening 321; the display member 100 is disposed on the side of the protective panel 200 away from the display surface 320 and covers the display opening 321, the protective panel 200 covering the display member 100.

[0053] In this embodiment, the display element 100 is disposed within the enclosed space, and the display element 100 completely covers the display opening 321, while the protective panel 200 completely covers the display element 100.

[0054] Part of the structure of the protective panel 200 is embedded in the mounting groove 311, and the display element 100 is located on the side of the protective panel 200 away from the display surface 320, and the protective panel 200 covers the display element 100. This structural design allows the non-display areas (such as drive lines and bonding areas) at the edge of the display element 100 to be blocked by the edge of the display surface 320 of the mounting element 300, without the need to hide these non-display structures by widening the frame of the mounting element 300. This not only effectively narrows the visual width of the mounting element 300, but also reduces the black border of the display device.

[0055] Reference Figure 1 and Figure 2 In one embodiment, the first mounting surface 310 is provided with a clearance groove 312. The clearance groove 312 is located on the side of the mounting groove 311 away from the display surface 320 and communicates with the mounting groove 311. Part of the structure of the display component 100 is embedded in the clearance groove 312.

[0056] The recessed groove 312 not only serves to avoid interference between the mounting component 300 and the display component 100, ensuring the structural integrity of the display component 100, but also allows a portion of the display component 100 to be embedded within the recessed groove 312. The groove wall of the recessed groove 312 can physically limit the display component 100, thereby restricting its movement on the mounting component 300 and effectively improving its stability on the mounting component 300.

[0057] Reference Figures 2 to 6 In one embodiment, the mounting member 300 further has a second mounting surface 330 disposed adjacent to the first mounting surface 310, the second mounting surface 330 being provided with a pressing groove 331 communicating with the mounting groove 311; the pressing member 400 includes a pressing body 410, the pressing body 410 passing through the pressing groove 331 and pressing the protective panel 200 against the inner wall surface of the mounting groove 311.

[0058] In this embodiment, the second mounting surface 330 and the display surface 320 are disposed opposite to each other along the thickness direction of the mounting member 300; the pressing body 410 is a pressing strip or a pressing block. In addition, in order to ensure that the pressing body 410 does not damage the protective panel 200, foam is provided on the surface of the pressing body 410 near the protective panel 200.

[0059] On the one hand, the pressing groove 331 is connected to the mounting groove 311, so that the pressing force applied by the pressing body 410 can be directly transmitted to the inner wall surface of the mounting groove 311, thereby forming a two-way constraint (i.e. the pressing force applied by the pressing body 410 and the bearing capacity applied by the mounting groove 311). Compared with simply pressing from one side, it can more stably prevent the protective panel 200 from detaching from the mounting groove 311, effectively improving the fixing strength of the protective panel 200.

[0060] On the other hand, the second mounting surface 330 is arranged adjacent to the first mounting surface 310, and the pressing groove 331 is arranged in the mounting member 300; the above structural design avoids the pressing member 400 occupying the external space of the display device, which helps to reduce the overall volume of the display device.

[0061] Reference Figures 3 to 6 In one embodiment, the pressing member 400 further includes a connector 420 disposed on the pressing member 410; the connector 420 is detachably mounted on the mounting member 300.

[0062] In this embodiment, the connector 420 is a connecting strip, and the connector 420 and the pressing body 410 are integrally formed parts. It is understood that the connector 420 and the pressing body 410 can also be fixedly connected by connecting screws, welding, or other connection methods. The connector 420 is detachably mounted on the mounting part 300 by connecting screws. It is also understood that the connector 420 can be detachably mounted on the mounting part 300 by a magnetic structure, a snap-fit ​​structure, or a plug-in structure.

[0063] On the one hand, when the protective panel 200 or the display component 100 needs to be repaired or replaced, the pressure body 410 can be quickly removed by disassembling the connector 420 without damaging the mounting component 300 or the protective panel 200. This not only simplifies the process of later maintenance and component replacement, but also effectively reduces maintenance costs.

[0064] On the other hand, the connector 420 and the mounting part 300 are detachably connected, without relying on a complex one-piece molding process. The mounting part 300 and the pressing part 400 can be processed independently, which reduces the manufacturing difficulty and mold cost.

[0065] In addition, to strengthen the connection between the pressing member 400 and the mounting member 300, there are two connectors 420, which are respectively arranged on opposite sides of the pressing member 410.

[0066] Reference Figures 3 to 6 In one embodiment, the pressing member 400 further includes a connector 420, which is disposed on the pressing member 410; the second mounting surface 330 is provided with a connecting groove 332, the connector 420 passes through the connecting groove 332, and the surface of the connector 420 away from the mounting member 300 is a connecting back surface 421, which is flush with the second mounting surface 330 or located on the side of the second mounting surface 330 near the protective panel 200.

[0067] In this embodiment, the connector 420 is a connector strip, and the connector 420 and the pressing body 410 are integrally formed. The connecting back side 421 is flush with the second mounting surface 330. It can be understood that the connecting back side 421 may also be located on the side of the second mounting surface 330 near the protective panel 200.

[0068] The connector back 421 is flush with or located on the side near the protective panel 200, preventing the connector 420 from protruding from the second mounting surface 330. This creates a flat and continuous appearance on the second mounting surface 330 of the mounting component 300, eliminating any abruptness and eliminating the need for additional space outside the second mounting surface 330, thus reducing the thickness of the display device. Furthermore, the fact that the connector 420 does not protrude from the second mounting surface 330 prevents users from being scratched by the protruding connector 420 during operation or handling, or from deforming or loosening the connector 420 due to impact, enhancing safety during use.

[0069] Reference Figures 3 to 6 In one embodiment, to further enhance the stability of the protective panel 200 on the mounting member 300, a plurality of pressing members 400 are provided, and the plurality of pressing members 400 are arranged at intervals along the circumference of the mounting member 300.

[0070] Reference Figure 1 , Figure 3 as well as Figures 7 to 12 In one embodiment, the display device further includes an optical element 500, which is located on the side of the display element 100 away from the protective panel 200; one of the optical element 500 and the mounting member 300 is provided with a connecting protrusion 314, and the other is provided with a connecting hole 5111, and the optical element 500 is installed in the mounting member 300 by being inserted into the connecting hole 5111 through the connecting protrusion 314.

[0071] In this embodiment, the optical component 500 is an optical film 510 (such as a diffusion film or a brightness enhancement film) or a diffusion plate 520. To avoid interference between the optical component 500 and the mounting component 300, the first mounting surface 310 is provided with a mounting groove 313, which penetrates the second mounting surface 330. The connecting protrusion 314 is a connecting protrusion post, which is disposed in the mounting groove 313 along the thickness direction of the optical component 500. The thickness direction of the optical component 500 is parallel to the thickness direction of the mounting component 300. The optical component 500 has a connecting protrusion 511, on which a connecting hole 5111 is provided. The extending direction of the connecting hole 5111 is parallel to the length direction of the connecting protrusion 314. To ensure the reliability of the connection between the optical component 500 and the mounting component 300, the wall of the connecting hole 5111 is an annular wall. It is understandable that the connecting protrusion 314 may also be provided on the optical component 500, and the connecting hole 5111 may be provided on the first mounting surface 310 of the mounting component 300.

[0072] The connecting protrusion 314 and connecting hole 5111 used in conjunction not only effectively prevent the optical component 500 from shaking on the mounting member 300, enhancing the stability of the optical component 500 mounted on the mounting member 300, but also simplify the assembly process. No complex alignment tools are needed; the initial positioning of the optical component 500 can be quickly completed through the guiding action of the connecting protrusion 314 and connecting hole 5111. Furthermore, the disassembly process is simplified, improving the maintainability of the optical component 500. Additionally, by placing the connecting protrusion 314 on the first mounting surface 310, the mounting member 300 can surround the outer periphery of the optical component 500, thereby reducing the overall size of the display device.

[0073] In addition, to enhance the stability of the optical component 500 mounted on the mounting component 300, there are multiple connecting protrusions 314, which are spaced apart along the circumference of the mounting component 300; the number of connecting holes 5111 is the same as the number of connecting protrusions 314, and the multiple connecting holes 5111 are respectively provided in one-to-one correspondence with the multiple connecting protrusions 314.

[0074] Reference Figure 1 , Figure 3 as well as Figures 7 to 12 In one embodiment, the display device further includes an optical element 500 located on the side of the display element 100 away from the protective panel 200; one of the optical element 500 and the mounting member 300 is provided with a limiting protrusion 521 and the other is provided with a limiting groove 315, and the optical element 500 is inserted into the limiting groove 315 through the limiting protrusion 521 to limit its movement on the mounting member 300.

[0075] In this embodiment, the optical element 500 is an optical film 510 (such as a diffusion film or a brightness enhancement film) or a diffusion plate 520; a limiting protrusion 521 is disposed on the optical element 500 and is disposed along the thickness direction of the optical element 500, the thickness direction of the optical element 500 being parallel to the thickness direction of the mounting member 300; a limiting groove 315 is disposed on the first mounting surface 310 and penetrates the second mounting surface 330, the extending direction of the limiting groove 315 being parallel to the length direction of the limiting protrusion 521; the optical element 500 is inserted into the limiting groove 315 through the limiting protrusion 521 to limit its movement on the mounting member 300 along the length or width direction of the mounting member 300. It can be understood that the limiting protrusion 521 may also be disposed on the mounting member 300, and the limiting groove 315 may be disposed on the optical element 500.

[0076] The matching limiting protrusion 521 and limiting groove 315 not only restrict the optical component 500 from swaying freely on the mounting member 300, ensuring the stability of the optical component 500 on the mounting member 300, but also serve as a pre-positioning basis for the optical component 500. Without the need for complex alignment tools, the initial positioning of the optical component 500 can be quickly completed through the guiding action of the limiting protrusion 521 and limiting groove 315. Furthermore, by setting the limiting groove 315 on the first mounting surface 310, the mounting member 300 can surround the outer periphery of the optical component 500, thereby reducing the overall size of the display device.

[0077] In addition, to enhance the stability of the optical component 500 mounted on the mounting component 300, there are multiple limiting protrusions 521, which are spaced apart along the circumference of the optical component 500; the number of limiting grooves 315 is the same as the number of limiting protrusions 521, and the multiple limiting grooves 315 are respectively provided in one-to-one correspondence with the multiple limiting protrusions 521.

[0078] Reference Figure 1 , Figure 3 as well as Figures 7 to 12 In one embodiment, there are two optical elements 500, one of which is an optical film 510 and the other is a diffuser plate 520. The diffuser plate 520 is disposed on the side of the optical film 510 away from the display element 100.

[0079] In this embodiment, the optical diaphragm 510 is provided with a connecting hole 5111, and the first mounting surface 310 of the mounting member 300 is provided with a connecting protrusion 314; the diffuser plate 520 is provided with a limiting protrusion 521, and the first mounting surface 310 of the mounting member 300 is provided with a limiting groove 315. It is understood that both the optical diaphragm 510 and the diffuser plate 520 may be provided with connecting holes 5111, or both may be provided with limiting protrusions 521, or the optical diaphragm 510 may be provided with limiting protrusions 521 and the diffuser plate 520 may be provided with connecting holes 5111.

[0080] The diffuser plate 520 can disperse the concentrated light emitted by the point light source or line light source and convert it into a surface light source, providing a uniform incident light basis for the subsequent optical film 510. The optical film 510 is located between the diffuser plate 520 and the display device 100, which can further refine the diffused light. Based on the initial light uniformity of the diffuser plate 520, it can eliminate the remaining brightness unevenness and make the light finally projected onto the display device 100 more uniform.

[0081] Reference Figure 1 , Figure 3 as well as Figures 7 to 12 In one embodiment, the optical element 500 covers the display element 100. In this embodiment, the optical element 500 completely covers the display element 100.

[0082] The optical element 500 covers the display element 100, ensuring that all light emitted from or incident on the display element 100 is processed by the optical element 500, thus avoiding problems such as local light leakage and uneven edge brightness caused by incomplete coverage.

[0083] Reference Figure 1 and Figure 7 In one embodiment, the mounting component 300 further has a second mounting surface 330 disposed adjacent to the first mounting surface 310. The first mounting surface 310 is provided with a receiving groove 316 penetrating the second mounting surface 330, and a portion of the structure of the optical component 500 is embedded in the receiving groove 316.

[0084] Part of the structure of the optical component 500 is embedded in the receiving groove 316. This structural design not only reduces the size of the display device in the thickness direction of the mounting component 300, but also the boundary of the receiving groove 316 forms a physical limit on the optical component 500, preventing the optical component 500 from shaking on the mounting component 300 and enhancing the stability of the optical component 500 on the mounting component 300.

[0085] Reference Figure 1 and Figure 7 In one embodiment, the display device further includes a reflective sheet 600 disposed on the mounting member 300 and located on the side of the optical element 500 away from the display member 100, and covering the optical element 500.

[0086] In this embodiment, the reflector 600 completely covers the optical element 500, and part of the structure of the reflector is located within the receiving groove 316.

[0087] The reflective sheet 600 covers the surface of the optical component 500 away from the display component 100, which can reflect the light that escapes to the non-display direction during the transmission of light by the optical component 500 back into the optical component 500, so that the light can re-participate in the light transmission and finally be projected onto the display component 100, thereby forming a secondary utilization, improving the utilization rate of light, and enhancing the display brightness of the display component 100.

[0088] Reference Figure 1 as well as Figure 7 In one embodiment, the display device further includes a back plate 700, which is detachably mounted on the mounting member 300 and located on the side of the optical element 500 away from the display member 100, and covers the optical element 500. The surface of the back plate 700 near the optical element 500 is used to restrict the movement of the optical element 500 in a direction away from the display member 100.

[0089] In this embodiment, the back plate 700 is detachably mounted on the mounting member 300 by connecting screws; the back plate 700 is located on the side of the reflector 600 away from the optical element 500 and covers the optical element 500 and the reflector 600.

[0090] The backplate 700 not only serves as a barrier, thereby enhancing the installation stability of the optical component 500, but also provides protection, preventing foreign objects from directly contacting the optical component 500 and extending its service life.

[0091] Reference Figure 1 , Figure 7 as well as Figure 13 In one embodiment, one of the back plate 700 and the mounting member 300 is provided with a positioning protrusion 710 and the other is provided with a positioning groove 333. The back plate 700 is inserted into the positioning groove 333 through the positioning protrusion 710 and positioned with the mounting member 300.

[0092] In this embodiment, a positioning protrusion 710 is disposed on the back plate 700. The positioning protrusion 710 is a positioning ring strip disposed circumferentially along the back plate 700 and disposed along the thickness direction of the mounting member 300. A positioning groove 333 is disposed on the second mounting surface 330 of the mounting member 300. The positioning groove 333 is a positioning ring groove disposed circumferentially along the mounting member 300 and disposed along the thickness direction of the mounting member 300. It can be understood that the positioning protrusion 710 may also be disposed on the mounting member 300 and the positioning groove 333 may be disposed on the back plate 700.

[0093] The positioning protrusion 710 and positioning groove 333 used in conjunction not only serve a positioning function, improving the positioning accuracy of the back plate 700 and the mounting part 300, but also serve a limiting function, enhancing the stability of the back plate 700 installed on the mounting part 300.

[0094] In summary, the display device provided in this embodiment has at least the following beneficial technical effects: In this application, the protective panel 200 is first initially positioned on the mounting component 300, forming a basis for mechanical contact; then, the pressing component 400 applies continuous pressing pressure to the protective panel 200, making the protective panel 200 securely mounted on the mounting component 300. The pressing component 400 is not only far less affected by ambient temperature and vibration than glue, but can also apply stable pressing pressure to the protective panel 200 for a long time, effectively improving the stability of the protective panel 200 mounted on the mounting component 300; at the same time, it does not rely on the glue curing process, shortening the assembly time and improving the assembly efficiency. Furthermore, by mounting the protective panel 200 on the mounting member 300 and pressing the protective panel 200 against the mounting member 300 using the pressing member 400, this structural design avoids the need to use a middle frame to support and install the protective panel 200. This not only reduces manufacturing costs but also avoids the need for the mounting member 300 to expand outwards due to the presence of a middle frame, effectively reducing the size of the display device and the black border of the display, which is conducive to achieving a narrow bezel design for the display device.

[0095] The above description is merely a preferred embodiment 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.
