Description

Technical Field

[0002] Medical displays and other display devices, due to their unique application requirements, usually need to have a cover plate installed on the light-emitting side of the display module to protect the display module.

The contact between the outer frame and the cover plate will generate a certain compressive stress on the cover plate. However, due to the inevitable manufacturing tolerances and / or assembly tolerances of structural components such as the outer frame and adapters, or because the connection between the back plate of the assembly module and / or the adapters and the outer frame will affect the flatness of the outer frame, the outer frame will generate compressive stress on the cover plate.

[0050] The technical solutions of the embodiments of this disclosure 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 disclosure, and not all of them.

[0052] It should be noted that in the following embodiments of this disclosure, the definitions of "parallel" and "perpendicular" are not absolute values ​​in a mathematical sense, and a certain degree of error and fluctuation is allowed.

[0053] This disclosure is described below with reference to the accompanying drawings and specific embodiments:

[0054] In related technologies, the cover plate 20 is usually assembled on the outer frame 100 of the assembly module. The contact between the outer frame 100 and the cover plate 20 will generate a certain compressive stress on the cover plate 20. However, due to the inevitable manufacturing tolerances and / or assembly tolerances of structural components such as the outer frame 100 and the adapter plate 310, or because the connection between the back plate 200 and / or the adapter plate 310 of the assembly module and the outer frame 100 will affect the flatness of the outer frame 100, the outer frame 100 will generate compressive stress on the cover plate 20. The compressive stress is transmitted to the display module 30, which will cause uneven stress on the display module 30 and produce yellow spots and / or light leakage defects.

[0055] To address the technical problem of yellow spots and / or light leakage defects in the display module 30 caused by the compressive stress generated by the outer frame 100 on the cover plate 20 being transmitted to the display module 30, embodiments of this disclosure propose an assembly module, such as... Figures 1 to 2 , Figures 5 to 10 As shown, the assembly module includes an outer frame 100, a back plate 200, and several adapter components 300. The outer frame 100 includes an outer outer plate 110 and an outer support plate 120 connected to the outer outer plate 110. The outer support plate 120 has a first support side and a second support side disposed opposite to each other. The first support side is used to support the cover plate 20. The back plate 200 includes a rear plate 210 and a connecting plate 220 surrounding the rear plate 210. The rear plate 210 is located on the non-light-emitting side of the cover plate 20 and is spaced apart from the cover plate 20 to form a receiving cavity between the rear plate 210 and the cover plate 20. The adapter components 300 include a transfer plate and at least one... The elastic buffer 320 and the adapter plate 310 include a first adapter portion 311 and a second adapter portion 312 connected to the first adapter portion 311. The first adapter portion 311 is used to connect to the connecting plate 220, and the second adapter portion 312 is used to connect to the outer support plate 120 and is located on the second support side of the outer support plate 120. The elastic buffer 320 is elastically supported between the second adapter portion 312 and the second support side and / or the elastic buffer 320 is elastically supported between the first adapter portion 311 and the connecting plate 220.

[0056] The assembly module proposed in the embodiments of this disclosure, such as Figures 1 to 2 , Figures 5 to 10 As shown, on the one hand, the outer frame 100 and the back panel 200 are connected by several adapter components 300. By having the elastic buffer 320 in the adapter component 300 elastically supported between the second adapter portion 312 and the second support side and / or the elastic buffer 320 elastically supported between the first adapter portion 311 and the connecting plate 220, the deformation of the elastic buffer 320 can offset manufacturing errors and assembly errors and absorb compressive stress. This can, to a certain extent, prevent the compressive stress from being transmitted to the display module 30, and further, to a certain extent, prevent the display module 30 from being subjected to excessive force. This can lead to yellow spots and / or light leakage defects. On the other hand, the outer frame 100 and the back panel 200 are connected by several adapter components 300. The adapter components 300 are not only small in size, but also independent of the outer frame 100 and the back panel 200 and have an adjustable installation position. Different sizes of assembly modules can be connected using different numbers of adapter components 300, which can improve the versatility and compatibility of the adapter components 300. This allows the adapter components 300 to be applied to assembly modules of different sizes, which can reduce the cost of assembly modules and display devices to a certain extent.

[0057] In some embodiments of this disclosure, such as Figures 1 to 2 , Figures 5 to 10 As shown, the first support side of the outer support plate 120 of the outer frame 100 is used to support the cover plate 20. It is necessary to ensure the flatness of the first support side so that the first support side fits with the four edges of the cover plate 20, thereby avoiding the cover plate 20 from being subjected to compressive stress and affecting the display module 30. In this way, the display module 30 can be prevented from producing yellow spots and / or light leakage defects due to uneven force.

[0058] In related technologies, although there are technical solutions that adjust the relative position between the outer frame 100 and the back plate 200 by adjusting the height of connecting parts such as screws, thereby adjusting the flatness of the mating surface between the outer frame 100 and the cover plate 20, such technical solutions require the adjustment of connecting parts such as screws. On the one hand, a large number of connecting parts such as screws need to be manually adjusted, which is not convenient. On the other hand, during the adjustment process, there is not only a risk of transmitting compressive stress to the cover plate 20 and the display module 30, but also the introduction of adjustment errors. Therefore, it cannot effectively ensure the flatness of the mating surface between the outer frame 100 and the cover plate 20, or solve the yellow spots and / or light leakage defects caused by uneven stress on the display module 30.

[0059] In the assembly module, the outer frame 100 also needs to be connected to the back plate 200. If the outer frame 100 and the back plate 200 are directly connected by screws or other connectors, a rigid connection is formed between the outer frame 100 and the back plate 200. When there are manufacturing or assembly tolerances in the outer frame 100 and / or the back plate 200, compressive stress will be generated, which will affect the flatness of the first support side. This will cause the first support side to not be able to fully fit with the four edges of the cover plate 20, resulting in yellow spots and / or light leakage defects in the display module 30. If the outer frame 100 and the back plate 200 are respectively connected to the adapter plate 310 by screws or other connectors to form the outer frame 100 The structure indirectly connected to the back panel 200 via the adapter plate 310 will also form a rigid connection between the outer frame 100 and the back panel 200. If there are manufacturing tolerances in any one or more of the outer frame 100, the back panel 200 and the adapter plate 310, or if there are assembly tolerances between the outer frame 100, the back panel 200 and the adapter plate 310, extrusion stress will be generated, which will affect the flatness of the first support side. This will cause the first support side to not be able to fit completely with the four edges of the cover plate 20, and will transfer the extrusion stress to the display module 30, which will cause the display module 30 to produce yellow spots and / or light leakage defects due to uneven stress. When the outer frame 100 and the back panel 200 are connected via the adapter plate 310, i.e., the outer support plate 120 of the outer frame 100 is connected to the second adapter portion 312 of the adapter plate 310, and the connecting plate 220 of the back panel 200 is connected to the first adapter portion 311 of the adapter plate 310, since there is an assembly angle between the outer support plate 120 and the connecting plate 220, the manufacturing angle between the first adapter portion 311 and the second adapter portion 312 and the assembly angle between the outer support plate 120 and the connecting plate 220 need to be matched. However, in practice, due to the existence of manufacturing tolerances and assembly tolerances, the manufacturing angle between the first adapter portion 311 and the second adapter portion 312 and the assembly angle between the outer support plate 120 and the connecting plate 220 often do not match. For example, if the assembly angle between the outer support plate 120 and the connecting plate 220 is 90°, then the manufacturing angle between the first transition part 311 and the second transition part 312 should also be 90°. However, due to manufacturing tolerances, in practice, the assembly angle between the outer support plate 120 and the connecting plate 220, and the manufacturing angle between the first transition part 311 and the second transition part 312, are often not exactly 90°, but generally fluctuate within the range of 90°±1°. When the transition plate 310 is connected to the outer support plate 120, the difference between the manufacturing angle and the assembly angle of the transition plate 310 will cause the transition plate 310 to cause the outer support plate 120 to rotate at an angle, thereby affecting the flatness of the first support side of the outer support plate 120 and generating a certain compressive stress. The compressive stress is transmitted to the display module 30 through the cover plate 20, resulting in defects such as light leakage and / or yellow spots. Studies have found that the change in the manufacturing angle of the transition plate 310 is the main cause of light leakage in the display device. Figure 3As shown, assuming the assembly angle between the outer support plate 120 and the connecting plate 220 is 90°, if the manufacturing tolerance of the adapter plate 310 causes the manufacturing angle between the first adapter part 311 and the second adapter part 312 to be greater than 90°, then after the outer frame 100 and the back plate 200 are connected through the adapter plate 310, the portion of the first adapter part 311 near the outer side plate 110 will generate a large compressive stress on the outer support plate 120, causing the outer support plate 120 to deform and affecting the fit between the outer support plate 120 and the edge of the cover plate 20. Simultaneously, the compressive stress will also be transmitted to the display module 30, causing the display module 30 to develop yellow spots and / or light leakage defects due to uneven stress. Figure 4 As shown, assuming the assembly angle between the outer support plate 120 and the connecting plate 220 is 90°, if the manufacturing tolerance of the adapter plate 310 causes the manufacturing angle between the first adapter part 311 and the second adapter part 312 to be less than 90°, then after the outer frame 100 and the back plate 200 are connected through the adapter plate 310, the part of the first adapter part 311 near the connecting plate 220 will generate a large compressive stress on the outer support plate 120, causing the outer support plate 120 to deform and affecting the fit between the outer support plate 120 and the edge of the cover plate 20. At the same time, the compressive stress will also be transmitted to the display module 30, causing the display module 30 to produce yellow spots and / or light leakage defects due to uneven stress.

[0060] In some embodiments of this disclosure, such as Figures 1 to 2 , Figures 5 to 10 As shown, by elastically supporting the elastic buffer 320 between the second adapter 312 and the second support side and / or elastically supporting the elastic buffer 320 between the first adapter 311 and the connecting plate 220, on the one hand, the deformation of the elastic buffer 320 can offset the angular difference between the assembly angle and the manufacturing angle, so that the size of the assembly angle and the manufacturing angle are matched. Then, after the outer frame 100 and the back plate 200 are connected by the adapter assembly 300, the flatness of the outer support plate 120 can be ensured. On the other hand, the elastic buffer 320 can buffer the compressive stress, so the adapter plate 310 will not generate compressive stress on the outer support plate 120. This allows the first support side of the outer support plate 120 to fit with the edge of the cover plate 20, avoiding the transmission of compressive stress to the display module 30 through the outer support plate 120 and the cover plate 20. This, to a certain extent, achieves the purpose of avoiding yellow spots and / or light leakage defects in the display module 30 due to uneven force.

[0061] In some embodiments of this disclosure, the adapter assembly 300 may include an adapter plate and an elastic buffer 320. The elastic buffer 320 may be disposed between the second adapter portion 312 and the second support side, or the elastic buffer 320 may also be disposed between the first adapter portion 311 and the connecting plate 220.

[0062] In some embodiments of this disclosure, the adapter assembly 300 may further include a transition plate and a plurality of elastic buffers 320. The plurality of elastic buffers 320 may all be disposed between the second adapter portion 312 and the second support side, or the plurality of elastic buffers 320 may all be disposed between the first adapter portion 311 and the connecting plate 220, or the plurality of elastic buffers 320 may be disposed between the second adapter portion 312 and the second support side, and between the first adapter portion 311 and the connecting plate 220, respectively.

[0063] In some embodiments of this disclosure, optionally, the assembly module can select an appropriate number of adapter components 300 according to its own size, so that the adapter components 300 can be evenly distributed on the connection path between the outer frame 100 and the back plate 200 of the assembly module, so as to ensure that the force on the assembly module is balanced after assembly.

[0064] In some embodiments of this disclosure, the cover plate 20 can be a glass cover plate 20. When the display device is used in medical settings such as operating rooms, the display device needs to be frequently disinfected and wiped, so the glass cover plate 20 can protect the internal components of the display device.

[0065] In some embodiments of this disclosure, the outer frame 100 may be made of materials such as aluminum extrusion profiles.

[0066] In some embodiments of this disclosure, such as Figure 1 As shown, the outer frame 100 can be divided into a top side, a bottom side, a left side, and a right side. The top side and the bottom side can adopt a common design, and the left side and the right side can adopt a common design. Furthermore, the top side, the bottom side, the left side, and the right side can adopt a common design, so that the outer frame 100 can be extruded using a set of aluminum extrusion molds, thereby reducing product costs.

[0067] In some embodiments of this disclosure, the elastic buffer 320 may be made of a material with a certain degree of elasticity, such as stainless steel, galvanized steel sheet, etc.

The first connector 331 can be a screw or other commonly used connector in the art. The first connector 331 is located in the first connecting hole 3111 and the first fixing hole 222 to connect the first connecting portion 311 to the connecting plate 220. The second connecting portion 312 of the adapter plate 310 has a second connecting hole 3122, and the outer support plate 120 of the outer frame 100 has a second fixing hole 1222. The second connector 332 can be a screw or other commonly used connector in the art. The second connector 332 is located in the second connecting hole 3122 and the second fixing hole 1222 to connect the second connecting portion 312 to the outer support plate 120.

[0069] In some embodiments of this disclosure, the adapter assembly 300 may optionally include an adapter plate 310 and an elastic buffer 320, the elastic buffer 320 being elastically supported between the second adapter portion 312 and the second support side, and the center of the elastic buffer 320 may coincide with the center of the second connection hole 3122, so as to provide a balanced elastic support and buffering effect through the elastic buffer 320.

[0070] In some embodiments of this disclosure, optionally, such as Figure 2 , Figures 5 to 12 As shown, the adapter assembly 300 may include an adapter plate 310 and two elastic buffers 320. Both elastic buffers 320 are elastically supported between the second adapter portion 312 and the second support side, and the two elastic buffers 320 are located on opposite sides of the second connection hole 3122, so as to provide a balanced elastic support and buffering effect through the elastic buffers 320.

[0071] In some embodiments of this disclosure, optionally, such as Figure 9 and Figure 10As shown, the second fixing hole 1222 can be a blind hole. The elastic buffer 320 is elastically supported between the second adapter 312 and the second support side. The thickness of the second adapter 312, the maximum compressible dimension of the elastic buffer 320 in the thickness direction of the second adapter 312, the length of the second connector 332, and the depth of the second fixing hole 1222 can be comprehensively considered and determined so that after the second connector 332 passes through the second connecting hole 3122 of the second adapter 312 and connects to the second fixing hole 1222, the elastic buffer 320 can be compressed to a certain extent. The deformation of the elastic buffer 320 after compression can offset the difference between the manufacturing angle and the assembly angle of the adapter plate 310 and absorb the stress caused by the difference between the manufacturing angle and the assembly angle. Meanwhile, since the design comprehensively considers the thickness of the second adapter 312, the maximum compressible dimension of the elastic buffer 320 in the thickness direction of the second adapter 312, the length of the second connector 332, and the depth of the second fixing hole 1222, when assembling the second connector 332, there is no need to consider the depth to which the second connector 332 is screwed into the second fixing hole 1222. The second connector 332 can be directly screwed into the bottom of the second fixing hole 1222, thereby greatly reducing the assembly difficulty and improving the assembly accuracy. Optionally, after the second adapter 312 and the outer support plate 120 are connected by the second connector 332, the elastic buffer 320 is compressed to a certain extent to ensure that the elastic buffer 320 has a certain supporting force. Optionally, after the second adapter 312 is connected to the outer support plate 120 via the second connector 332, the elastic buffer 320 is compressed to a certain extent and can be further compressed. That is, at this time, the compression amount of the elastic buffer 320 is less than the maximum compressibility of the elastic buffer 320, so as to avoid the elastic buffer 320 being over-compressed and unable to rebound, and to ensure that the elastic buffer 320 can provide a certain support force.

[0072] As an alternative implementation, optionally, such as Figures 5 to 7 as well as Figure 11 As shown, the inner diameter of the first connecting hole 3111 is larger than the outer diameter of the first connector 331. When the adapter plate 310 is fastened by the first connector 331 through the first connecting hole 3111, space is reserved for the adapter plate 310 to move. That is, the adapter plate 310 can move to a certain extent in the length and width directions of the connecting plate 220, thereby further reducing the stress generated after fastening by the connecting assembly 330.

[0073] As an alternative implementation, optionally, such as Figures 5 to 7 as well as Figure 11As shown, the dimension of the first connecting hole 3111 in the length direction of the connecting plate 220 is smaller than the dimension of the first connecting hole 3111 in the height direction of the connecting plate 220. That is, the first connecting hole 3111 is waist-shaped, which provides space for the adapter plate 310 to move. In other words, the adapter plate 310 can move to a certain extent in the height direction of the connecting plate 220, thereby realizing the height adjustment of the installation position of the adapter plate 310 on the connecting plate 220 and reducing the stress generated after being fastened by the connecting component 330.

[0074] As an alternative implementation, optionally, such as Figures 5 to 7 as well as Figure 11 As shown, the inner diameter of the second connecting hole 3122 is larger than the outer diameter of the second connector 332. When the adapter plate 310 is locked through the second connecting hole 3122 via the second connector 332, space is reserved for the adapter plate 310 to move. That is, the adapter plate 310 can move to a certain extent in the length and width directions of the outer support plate 120, thereby further reducing the stress generated after being locked by the connecting assembly 330.

[0075] As an alternative implementation, optionally, such as Figures 5 to 7 as well as Figure 11 As shown, the second connecting hole 3122 is larger in length direction than the second connecting hole in width direction than the first connecting hole in width direction. That is, the second connecting hole 3122 is waist-shaped, which provides space for the adapter plate 310 to move. In other words, the adapter plate 310 can move to a certain extent in length direction of the outer support plate 120, thereby further reducing the stress generated after being fastened by the connecting assembly 330.

[0076] As an alternative implementation method, such as Figures 1 to 2 , Figures 5 to 10 As shown, the cross-section of the adapter plate 310 is L-shaped.

[0077] In some embodiments of this disclosure, such as Figures 1 to 2 , Figures 5 to 10 As shown, the cross-section of the adapter plate 310 is L-shaped, that is, there is only one manufacturing angle between the first adapter part 311 and the second adapter part 312. This can reduce the number of bends in the manufacturing process of the adapter plate 310, further reduce the stress caused by manufacturing errors due to the manufacturing angle formed by bending, and further reduce the risk of yellow spots and / or light leakage caused by uneven stress on the display module 30.

[0078] As an alternative implementation method, such as Figures 5 to 9As shown, the elastic buffer 320 includes a connecting portion 321 and an elastic contact portion 322 connected to the connecting portion 321. The connecting portion 321 is used to connect to the second adapter portion 312. The free end of the elastic contact portion 322 is used to abut against the second support side, and the included angle between the elastic contact portion 322 and the second adapter portion 312 is less than 90°.

[0079] In some embodiments of this disclosure, such as Figures 5 to 9 As shown, the free end of the elastic contact portion 322 is used to abut against the second support side, that is, the free end of the elastic contact portion 322 is a contact point that abuts against the second support side and forms a point contact with the second support side; by making the included angle between the elastic contact portion 322 and the second transition portion 312 less than 90°, when the second transition portion 312 and the outer support plate 120 are locked by the second connector 332, since the included angle between the elastic contact portion 322 and the second transition portion 312 is less than 90°, the free end of the elastic contact portion 322 can be subjected to a force that can generate a component parallel to the second support side, so that the free end of the elastic contact portion 322 can... The elastic contact portion 322 slides relative to the human support side, thereby compressing and bending the elastic contact portion 322 relative to the second transition portion 312 and forming a rebound angle, which can generate a rebound force. The rebound force provides elastic support between the second transition portion 312 and the second support side. At the same time, since the free end of the elastic contact portion 322 on the second support side is in point contact, the free end of the elastic contact portion 322 can slide relative to the second support side with low resistance during the compression and bending process of the elastic contact portion 322 relative to the second transition portion 312, and will not affect the compression and bending process of the elastic contact portion 322 relative to the second transition portion 312.

[0080] In some embodiments of this disclosure, such as Figures 5 to 9 As shown, optionally, the angle between the elastic contact portion 322 and the second transition portion 312 can be [30°, 90°), that is, the angle between the elastic contact portion 322 and the second transition portion 312 is greater than or equal to 30° and less than 90°. More optionally, the angle between the elastic contact portion 322 and the second transition portion 312 can be [45°, 75°], that is, the angle between the elastic contact portion 322 and the second transition portion 312 is greater than or equal to 45° and less than or equal to 75°. By making the angle between the elastic contact portion 322 and the second transition portion 312 greater than or equal to 30°, it is ensured that the elastic contact portion 322 can provide sufficient elastic force. If the angle between the elastic contact portion 322 and the second transition portion 312 is too small, the elastic force generated by the elastic contact portion 322 will be small, which will affect the stability and reliability of the connection between the second transition portion 312 and the outer support plate 120. In some embodiments, the included angle between the elastic contact portion 322 and the second transition portion 312 can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85°, etc.

[0081] As an alternative implementation method, such as Figure 5 , Figure 8 as well as Figure 9 As shown, the free end of the elastic contact portion 322 is provided with a flange 3221 or an arc-shaped surface, so that the surface of the free end of the elastic contact portion 322 that abuts against the second support side is arc-shaped.

[0082] In some embodiments of this disclosure, such as Figure 5 , Figure 8 as well as Figure 9 As shown, the free end of the elastic contact portion 322 is provided with a flange 3221. The flange 3221 structure can make the free end of the elastic contact portion 322 into an arc-shaped surface, thereby making the surface of the free end of the elastic contact portion 322 that abuts against the second support side arc-shaped. This allows the free end of the elastic contact portion 322 to make point contact with the second support side and slide relative to the second support side, reducing the frictional resistance of sliding.

[0083] As an alternative implementation method, such as Figure 5 As shown, the elastic buffer 320 and the second adapter 312 are an integral structure, and the elastic contact part 322 is formed by bending a portion of the second adapter 312 or by cutting and bending a portion of the second adapter 312.

[0084] In some embodiments of this disclosure, such as Figure 5 As shown, the elastic buffer 320 and the second transition portion 312 are integrally formed. The elastic buffer 320 can be formed by cutting a portion of the second transition portion 312 and bending that portion at a certain angle relative to the second transition portion 312. Optionally, the cut position on the second transition portion 312 can be located in the inner region of the second transition portion 312 or in the edge region of the second transition portion 312. It should be noted that, in order to make the rebound force generated by the elastic buffer 320 more even, the elastic buffer 320 is at least axially symmetrically distributed on the second transition plate 310.

[0085] In some embodiments of this disclosure, the elastic buffer 320 and the second adapter 312 are integrally formed. The elastic buffer 320 can be formed by bending a portion of the second adapter 312 at a certain angle relative to the second adapter 312. For example, the elastic buffer 320 can be formed by bending the second adapter 312 at the edge regions of opposite ends in the length direction of the outer support plate 120.

[0086] In some embodiments of this disclosure, optionally, such as Figure 5As shown, the elastic buffer 320 is formed by cutting the second transition portion 312. During the manufacturing process, a rectangular area can be cut out at a preset position of the second transition portion 312 as the elastic buffer 320, and one side of the rectangular area is kept connected to the second transition portion 312. Then, the cut rectangular area is bent towards the second transition portion 312 towards the outer support plate 120, thereby forming an elastic buffer 320 with an integral structure of the second transition portion 312. At the same time, the side / area that is connected to the second transition portion 312 after the rectangular area is bent is the connecting portion 321. The other areas of the rectangular area after bending are elastic contact portions 322. The end of the elastic contact portion 322 away from the second transition portion 312 is the free end of the elastic contact portion 322. The free end of the elastic contact portion 322 is used to abut against the second support side of the outer support plate 120. Optionally, the free end of the elastic contact portion 322 is provided with a flange 3221, so that the surface of the free end of the elastic contact portion 322 abutting against the second support side is arc-shaped. Optionally, the flange 3221 can be formed by bending the free end of the elastic contact portion 322. In such cases... Figure 5 In the illustrated embodiment, the second adapter portion 312 is provided with two elastic buffer members 320, which are positioned opposite each other on both sides of the second connecting hole 3122. When the second adapter portion 312 of the adapter plate 310 is connected to the second support side of the outer support plate 120, the elastic buffer member 320 is located between the second adapter portion 312 and the outer support plate 120. When the second connector 332 passes through the second connecting hole 3122 and is connected to the second fixing hole 1222 on the outer support plate 120, the elastic buffer member 320 can be compressed to deform in order to offset the difference between the manufacturing angle and the assembly angle of the adapter plate 310 and absorb the stress caused by the difference between the manufacturing angle and the assembly angle.

[0087] As an alternative implementation method, such as Figures 6 to 8As shown, the second adapter 312 has a buffer mounting hole 3121; the connecting part 321 includes a first spring arm 3211, a second spring arm 3212 opposite to the first spring arm 3211, a first support arm 3213 connected to the first spring arm 3211, a second support arm 3214 connected to the second spring arm 3212, and a connecting arm 3215 connecting the first spring arm 3211 and the second spring arm 3212. The connecting arm 3215 has a springback bend 32151. The lengths of the first support arm 3213 and the second support arm 3214 in the springback direction of the first spring arm 3211 and the second spring arm 3212 are greater than the buffer mounting hole 3121. 121 is the length of the first rebound arm 3211 and the second rebound arm 3212 in the rebound direction; the elastic contact part 322 includes a first elastic contact arm 3222 and a second elastic contact arm 3223, the first elastic contact arm 3222 is connected to the first support arm 3213, and the second elastic contact arm 3223 is connected to the second support arm 3214; the first rebound arm 3211 and the second rebound arm 3212 are used to pass through the buffer mounting hole 3121 and are engaged in the buffer mounting hole 3121 under the elastic force of the rebound bending 32151, and the first support arm 3213 and the second support arm 3214 are located on the side of the second transition part 312 near the second support side.

[0088] In some embodiments of this disclosure, such as Figures 6 to 8As shown, the first spring arm 3211 and the second spring arm 3212 are arranged opposite to each other and connected by a connecting arm 3215. A spring-loaded bend 32151 is provided on the connecting arm 3215. By compressing the first spring arm 3211 and the second spring arm 3212, the distance between the first spring arm 3211 and the second spring arm 3212 can be reduced, thereby allowing the connecting part 321, which consists of the first spring arm 3211, the second spring arm 3212, and the connecting arm 3215, to be placed in the second transition part 312. The buffer is installed in the buffer mounting hole 3121; the force pressing on the first spring arm 3211 and the second spring arm 3212 is removed. The first spring arm 3211 and the second spring arm 3212 move in opposite directions under the elastic force of the spring bending 32151, so that the first spring arm 3211 and the second spring arm 3212 can rebound under the elastic force of the spring bending 32151 and be locked in the buffer mounting hole 3121, so as to achieve the purpose of connecting the elastic buffer 320 to the second adapter 312. The first rebound arm 3211 is also connected to the first support arm 3213, and the second rebound arm 3212 is also connected to the second support arm 3214. This allows the first support arm and the second support arm 3214 to be positioned opposite each other. When the first rebound arm 3211 and the second rebound arm 3212 are engaged in the buffer mounting hole 3121, the first support arm 3213 and the second support arm 3214 can be located on the side of the second adapter 312 closer to the second support side. Furthermore, because the upward rebound length of the first support arm 3213 and the second support arm 3214 of the first support arm 3211 and the second rebound arm 3212 is greater than the buffer mounting hole 3121... The length of hole 3121 in the rebound direction of the first rebound arm 3211 and the second rebound arm 3212 is such that the elastic buffer 320 will not pass through the buffer mounting hole 3121 at the positions of the first support arm 3213 and the second support arm 3214. Simultaneously, the first support arm 3213 is also connected to the first elastic contact arm 3222, and the second support arm 3214 is also connected to the second elastic contact arm 3223. This allows the first elastic contact arm 3222 and the second elastic contact arm 3223 to be positioned opposite each other, and the first elastic contact arm 3222 and the second contact arm are also located on the side of the second adapter 312 closer to the second support side. After the elastic buffer 320 is connected to the second adapter 312 via the connecting part 321, it forms an adapter assembly 300.

[0089] In some embodiments of this disclosure, such as Figures 6 to 8 As shown, the second adapter 312 has a second connecting hole 3122, and buffer mounting holes 3121 are respectively provided on opposite sides of the second connecting hole 3122. Two elastic buffers 320 are connected to the second adapter 312 through the two buffer mounting holes 3121, thus forming a configuration as shown. Figure 6 The adapter component 300 shown.

[0090] In some embodiments of this disclosure, such as Figure 2 , Figures 6 to 9 As shown, when the second adapter 312 is assembled with the second support side of the outer support plate 120, the first support arm 3213, the second support arm 3214, the first elastic contact arm 3222, and the second elastic contact arm 3223 are located on the side of the second adapter 312 facing the outer support plate 120, that is, the first support arm 3213, the second support arm 3214, the first elastic contact arm 3222, and the second elastic contact arm 3223 are located between the second adapter 312 and the second support side. When the second connector 332 passes through the second connecting hole 3122 and connects to the second fixing hole 1222 on the outer support plate 120, the free ends of the first elastic contact arm 3222 and the second elastic contact arm 3223 abut against the second support side and are squeezed to produce a certain deformation. At the same time, the rebound force generated by the first elastic contact arm 3222 and the second elastic contact arm 3223 reacts to the second adapter 312, which can make the first support arm 3213 and the second support arm 3214 abut against the second adapter 312. That is, the two ends of the first elastic contact arm 3222 are compressed by the first support arm 3213 and the free end of the first elastic contact arm 3222 respectively, which reduces the angle between the first elastic contact arm 3222 and the first support arm 3213 and generates a rebound force. The two ends of the second elastic contact arm 3223 are compressed by the second support arm 3214 and the free end of the second elastic contact arm 3223 respectively, which reduces the angle between the second elastic contact arm 3223 and the second support arm 3214 and generates a rebound force. Thus, the deformation caused by the change in the angle between the first elastic contact arm 3222 and the first support arm 3213 and the angle between the second elastic contact arm 3223 and the second support arm 3214 can offset the difference between the manufacturing angle and the assembly angle of the adapter plate 310 and absorb the stress caused by the difference between the manufacturing angle and the assembly angle.

[0091] In some embodiments of this disclosure, optionally, such as Figure 2 , Figures 6 to 9 As shown, the connecting arm 3215 is connected to the end of the first spring arm 3211 away from the first support arm 3213 and the end of the second spring arm 3212 away from the second support arm 3214.

[0092] In some embodiments of this disclosure, optionally, such as Figure 2 , Figures 6 to 9 As shown, when the connecting arm 3215 is connected to the end of the first rebound arm 3211 away from the first support arm 3213 and the end of the second rebound arm 3212 away from the second support arm 3214, the rebound bend 32151 of the connecting arm 3215 can be oriented towards the second support side, thereby reducing the space occupied by the elastic buffer 320 in the thickness direction of the second transition portion 312.

[0093] In some other embodiments of this disclosure, the connecting arm 3215 may optionally be connected to other positions of the first spring arm 3211 and the second spring arm 3212. For example, the connecting arm 3215 may be connected to the middle region of the first spring arm 3211 and the middle region of the second spring arm 3212; in this case, the springback bend 32151 of the connecting arm 3215 may be towards the second support side, or the springback bend 32151 of the connecting arm 3215 may be away from the second support side. In this case, the direction of the springback bend 32151 of the connecting arm 3215 will not affect the space occupied by the elastic buffer 320 in the thickness direction of the second transition portion 312. For example, the connecting arm 3215 can be connected to the end of the first spring arm 3211 near the first support arm and the end of the second spring arm 3212 near the second support arm 3214. In this case, the spring bending direction of the connecting arm 3215 is preferably away from the second support side, so as to avoid interference between the spring bending 32151 and the first support arm 3213, the second support arm 3214, the first elastic contact arm 3222 and the second elastic contact arm 3223.

[0094] As an alternative implementation method, such as Figure 8 As shown, the bending angle of springback bend 32151 is greater than or equal to 90°.

[0095] In some embodiments of this disclosure, such as Figure 8 As shown, the first springback arm 3211 and the second springback arm 3212 generate a springback force through the springback bend 32151 of the connecting arm 3215. By ensuring that the bending angle of the springback bend 32151 is greater than or equal to 90°, it can be ensured that a large springback force is generated through the springback bend 32151 of the connecting arm 3215, causing the first springback arm 3211 and the second springback arm 3212 to spring back. If the bending angle of the springback bend 32151 is too small, after squeezing the first springback arm 3211 and the second springback arm 3212 and placing them into the buffer mounting hole 3121 on the second adapter 312, the connecting arm 3215 is easily compressed and deformed, making it unable to spring back.

[0096] In some embodiments of this disclosure, optionally, such as Figure 8As shown, the bending angle of the springback bend 32151 can be [90°, 180°), that is, the bending angle of the springback bend 32151 can be greater than or equal to 90° and less than 180°. Further optionally, the bending angle of the springback bend 32151 can be [105°, 165°], that is, the bending angle of the springback bend 32151 can be greater than or equal to 105° and less than or equal to 165°. By making the bending angle of the springback bend 32151 greater than or equal to 90°, it can be ensured that the connecting arm 3215 generates sufficient springback force; at the same time, by making the bending angle of the springback bend 32151 less than 180°, it can be ensured that the connecting arm 3215 deforms at the springback bend 32151 to generate springback force. In some embodiments, the bending angle of the springback bend 32151 can be 90°, 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 155°, 150°, 155°, 160°, 165°, 170°, 175°, etc.

[0097] As an alternative implementation method, such as Figure 2 , Figures 6 to 9 As shown, the first elastic contact arm 3222 bends relative to the first support arm 3213 toward the second elastic contact arm 3223, and the second elastic contact arm 3223 bends relative to the second support arm 3214 toward the first elastic contact arm 3222.

[0098] In some embodiments of this disclosure, such as Figure 2 , Figures 6 to 9 As shown, by bending the first elastic contact arm 3222 relative to the first support arm 3213 towards the second elastic contact arm 3223, and bending the second elastic contact arm 3223 relative to the second support arm 3214 towards the first elastic contact arm 3222, on the one hand, the space occupied by the first elastic contact arm 3222 and the second elastic contact arm 3223 in the upward rebound of the first rebound arm 3211 and the second rebound arm 3212 can be reduced, thereby facilitating the installation of the elastic buffer 320; on the other hand, when the elastic buffer 320 is compressed, the first elastic contact arm 3222 and the second elastic contact arm 3223 move towards each other, which can prevent the first elastic contact arm 3222 and the second elastic contact arm 3223 from increasing the space occupied by the first elastic contact arm 3222 and the second elastic contact arm 3223 in the upward rebound of the first rebound arm 3211 and the second rebound arm 3212 and interfering with the adjacent structure.

[0099] As an alternative implementation method, such as Figure 2 , Figures 6 to 9 As shown, the first support arm 3213 is in surface contact with the second support side, and the second support arm 3214 is in surface contact with the second support side.

[0100] In some embodiments of this disclosure, such as Figure 2 , Figures 6 to 9 As shown, by making the first support arm 3213 and the second support side in surface contact, and the second support arm 3214 in surface contact with the second support side, after the second transition portion 312 is connected to the outer support plate 120, the first support arm 3213 and the second support side can be fitted together, increasing the force-bearing area of ​​the second transition portion 312 and making the force on the second transition portion 312 more balanced. Optionally, the first support arm 3213 and the second support arm 3214 are parallel to the second support side, so that the first support arm 3213 and the second support arm 3214 can fit better with the second support side.

[0101] As an alternative implementation method, such as Figure 8 As shown, the first rebound arm 3211 has a first anti-detachment protrusion 3216 at the end away from the first support arm 3213; the second rebound arm 3212 has a second anti-detachment protrusion 3217 at the end away from the second support arm 3214.

[0102] In some embodiments of this disclosure, such as Figure 8 As shown, by providing a first anti-detachment protrusion 3216 at one end of the first rebound arm 3211 away from the first support arm 3213, and a second anti-detachment protrusion 3217 at one end of the second rebound arm 3212 away from the second support arm 3214, the first anti-detachment protrusion 3216 and the second anti-detachment protrusion 3217 can be arranged opposite to each other. The first anti-detachment protrusion 3216 and the second anti-detachment protrusion 3217 can, to a certain extent, prevent the elastic buffer 320 from falling off the second adapter 312.

[0103] As an optional implementation, the connecting plate 220 is provided with a first positioning protrusion 221 or a first positioning groove on the side facing the first adapter 311 for positioning the first adapter 311; and / or, the outer support plate 120 is provided with a second positioning protrusion 1221 or a second positioning groove on the second support side for positioning the second adapter 312.

[0104] In some embodiments of this disclosure, optionally, the connecting plate 220 is provided with a first positioning protrusion 221 or a first positioning groove on the side facing the first adapter 311. The first positioning protrusion 221 or the first positioning groove is used for positioning connection between the connecting plate 220 and the first adapter 311 to ensure that the back plate 200 and the backlight module 40 mounted on the back plate 200 are placed in the designated position without positional offset.

[0105] In some embodiments of this disclosure, optionally, the outer support plate 120 is provided with a second positioning protrusion 1221 or a second positioning groove on the second support side. The second positioning protrusion 1221 or the second positioning groove is used for positioning connection between the outer support plate 120 and the second adapter 312, so that the relative position of the outer frame 100, the adapter plate 310, and the back plate 200 is determined, thereby reducing assembly errors. At the same time, the second positioning protrusion 1221 and the second positioning groove can also prevent the adapter plate 310 from twisting during assembly.

[0106] In some embodiments of this disclosure, optionally, such as Figure 2 As shown, the connecting plate 220 has a first positioning protrusion 221 on the side facing the first adapter 311. When the back plate 200 is connected to the first adapter 311, the first positioning protrusion 221 can abut against the side of the first connecting portion 321 to determine the relative position of the back plate 200 and the first adapter 311. Optionally, the first connecting portion 321 may also have a first positioning notch that matches the first positioning protrusion 221.

[0107] In some embodiments of this disclosure, optionally, the connecting plate 220 is provided with a first positioning groove on the side facing the first adapter 311. When the back plate 200 is connected to the first adapter 311, the first adapter 311 can be placed in the first positioning groove to achieve the positioning connection between the first adapter 311 and the connecting plate 220.

[0108] In some embodiments of this disclosure, optionally, such as Figure 13 and Figure 14 As shown, the outer support plate 120 is provided with a second positioning protrusion 1221 on the second support side. When the outer support plate 120 is connected to the second adapter 312, the second positioning protrusion 1221 can abut against the side of the second adapter 312 or the side of the elastic buffer 320 on the second adapter 312 to determine the connection position between the outer support plate 120 and the second adapter 312, and can prevent the adapter plate 310 from twisting during assembly.

[0109] In some embodiments of this disclosure, optionally, the outer support plate 120 is provided with a second positioning groove on the second support side. When the outer support plate 120 is connected to the second adapter 312, the second adapter 312 can be placed in the second positioning groove to realize the connection position between the outer support plate 120 and the second adapter 312, and at the same time, it can also prevent the adapter plate 310 from twisting during assembly.

[0110] As an alternative implementation method, such as Figure 2 , Figure 9 as well as Figure 10 As shown, the assembly module also includes:

[0111] The cushioning foam 400 is disposed on the first support side and is located between the outer support plate 120 and the cover plate 20.

[0112] In some embodiments of this disclosure, such as Figure 2 , Figure 9 as well as Figure 10 As shown, by providing a buffer foam 400 on the first support side, the buffer foam 400 is supported between the outer support plate 120 and the cover plate 20. On the one hand, the deformation of the buffer foam 400 can further offset the angular difference between the assembly angle and the manufacturing angle, ensuring the flatness of the outer support plate 120; and further buffer the compressive stress, preventing the compressive stress from being transmitted to the display module 30 through the outer support plate 120 and the cover plate 20, thereby further preventing the display module 30 from developing yellow spots and / or light leakage defects due to uneven stress. On the other hand, the buffer foam 400 can seal the gap between the cover plate 20 and the first support side, improving the sealing performance and preventing the entry of foreign objects.

[0113] In some embodiments of this disclosure, optionally, such as Figure 2 , Figure 9 as well as Figure 10 As shown, the cushioning foam 400 can be provided with adhesive layers on both sides, and the two sides of the cushioning foam 400 can be bonded to the first support side and the cover plate 20 respectively through the adhesive layers.

[0114] As an alternative implementation method, such as Figures 9 to 18 As shown, the assembly module also includes: a middle frame 500, which includes an inner side plate 510 and an inner support plate 520 connected to the inner side; the inner side plate 510 is located on the side of the connecting plate 220 near the first transition part 311, and the inner side plate 510 has a first transition clearance groove 511 corresponding to the position of the first transition part 311; the inner support plate 520 is located on the side of the rear plate 210 away from the connecting plate 220, and the inner support plate 520 is used to support the display module 30.

[0115] In some embodiments of this disclosure, such as Figure 9 , Figure 10 , Figure 12 as well as Figure 16 As shown, the assembly module also includes a middle frame 500, which includes an inner side plate 510 and an inner support plate 520 connected to the inner side. The inner side plate 510 is located on the side of the connecting plate 220 near the first adapter 311, and the inner support plate 520 is located on the side of the rear plate 210 away from the connecting plate 220. The inner support plate 520 is used to support the display module 30.

[0116] In some embodiments of this disclosure, such as Figure 9 , Figure 10 Figure 12 as well as Figure 16 As shown, at the connection between the first adapter portion 311 of the adapter plate 310 and the connecting plate 220, the presence of the inner side plate 510 of the middle frame 500 interferes with the connection between the first adapter portion 311 and the connecting plate 220. By providing a first adapter clearance groove 511 corresponding to the position of the first adapter portion 311 in the inner side plate 510, the first adapter portion 311 can be directly connected to the connecting plate 220 by avoiding the first adapter portion 311 through the first adapter clearance groove 511. Compared with the traditional method of indirect connection between the adapter plate 310 and the back plate 200 / connecting plate 220 through the middle frame 500, the embodiment of this disclosure directly connects the first adapter portion 311 to the connecting plate 220, which can reduce the compression of the middle frame 500 after the adapter plate 310 is locked and avoid the transmission of compressive stress to the display module 30 through the middle frame 500, thereby further reducing the risk of yellow spots and / or light leakage in the display device.

[0117] In some embodiments of this disclosure, such as Figure 9 , Figure 10 Figure 12 as well as Figure 16 As shown, a panel buffer pad 522 may be provided on the side of the inner support plate 520 near the display module 30 to support the display module 30. A backlight buffer pad 523 may be provided on the side of the inner support plate 520 near the backlight module 40 to limit the position of the backlight module 40 through the buffer pad of the back plate 200 and prevent the backlight module 40 from shifting.

[0118] As an alternative implementation method, such as Figures 15 to 18 As shown, the middle frame 500 also includes a first nested plate 521 connected to the inner support plate 520 and extending toward the rear plate 210; the back plate 200 also includes a second nested plate 230 connected to the rear plate 210 and extending toward the inner support plate 520, the second nested plate 230 being located between the inner side plate 510 and the first nested plate 521.

[0119] In some embodiments of this disclosure, such as Figures 15 to 18As shown, the middle frame 500 includes a first nested plate 521 connected to the inner support plate 520 and extending towards the rear plate 210; the back plate 200 includes a second nested plate 230 connected to the rear plate 210 and extending towards the inner support plate 520. After the assembly module is assembled, the second nested plate 230 can be located between the inner side plate 510 and the first nested plate 521, that is, the first nested plate 521 and the second nested plate 230 can be interlocked, thus forming a tortuous groove-shaped sealed space between the middle frame 500 and the back plate 200. This tortuous groove-shaped sealed space can effectively prevent foreign objects from entering the assembly module, improve the foreign object entry prevention performance of the assembly module, and enable the assembly module to meet the application scenarios with more stringent requirements for foreign objects, such as medical display devices. In addition, the back panel 200 often has several perforated structures for fixing or engaging various films of the backlight module 40 and / or display module 30. Through the interlocking structure of the first nesting plate 521 and the second nesting plate 230, the perforated structures on the back panel 200 are covered, and the perforated structures on the back panel 200 are wrapped to prevent foreign objects from entering the assembly module through the perforated structures. There is no need to stick dustproof tape or other dustproof structures on the perforated structures of the back panel 200, which can reduce the workload and reduce product costs to a certain extent.

[0120] In some embodiments of this disclosure, such as Figures 15 to 18 As shown, the first nesting plate 521 and the second nesting plate 230 can be intermittently set according to the position of the perforation structure on the back plate 200. That is, the middle frame 500 can be provided with multiple first nesting plates 521, and the back plate 200 can be provided with second nesting plates 230 that correspond one-to-one with the number and position of the first nesting plates 521, thereby forming a groove-shaped sealed space corresponding to the position of the perforation structure.

[0121] As an alternative implementation method, such as Figure 1 , Figure 19 as well as Figure 20 As shown, the assembly module also includes a protective cover 600, which is connected to the side of the rear plate 210 away from the cover plate 20 and forms a protective cavity between the protective cover 600 and the rear plate 210. The protective cover 600 is provided with a second transition clearance groove for avoiding the second transition part 312.

[0122] In some embodiments of this disclosure, such as Figure 1 , Figure 19 as well as Figure 20As shown, the assembly module also includes a protective cover 600. By connecting the protective cover 600 to the side of the back plate 210 away from the cover plate 20, a protective cavity is formed between the protective cover 600 and the back plate 210. The protective cavity can be used to arrange structures that need to be protected, such as circuit boards (PCBs) and / or chip on film (COF311), according to design requirements. Meanwhile, the protective cover 600 is provided with a second transition clearance groove for avoiding the first transition part 311. Thus, a protective cavity is formed between the protective cover 600 and the back plate 210 for the assembly process of the back plate 200 and the outer frame 100 after the PCB and / or COF311. Since the protective cover 600 is provided with a second transition clearance groove for avoiding the second transition part 312, it is not necessary to remove the protective cover 600. The protective cover 600 is left on the back plate 200, so that the protective plate and the back plate 200 form an integrated protective structure to wrap and protect the PCB and / or COF311. Thus, the design of the protective cover 600 is compatible with both the shipment of the display module 30 and the shipment of the complete display device, achieving a compatible design and effectively reducing costs. At the same time, it can also protect the PCB and / or COF311 in real time during the assembly process of the back plate 200 and the outer frame 100, improve the yield of the assembly process, and simplify the assembly steps.

[0123] Based on the same inventive concept, this disclosure also proposes a display device, such as... Figure 1 , Figure 9 as well as Figure 20 As shown, the display device includes a cover plate 20, a display module 30, a backlight module 40, and the aforementioned assembly module. The display module 30 is located on the side of the cover plate 20 near the back plate 210; the backlight module 40 is located between the display module 30 and the back plate 210.

[0124] Since the display device provided by the present invention includes the assembly module of the above-mentioned technical solution, the display device provided by the present invention has all the beneficial effects of the above-mentioned assembly module, which will not be elaborated here.

[0125] As an alternative implementation method, such as Figure 1 As shown, the display device also includes several functional cards 50 connected to the display module 30. The functional cards 50 are located on the side of the rear plate 210 away from the cover plate 20.

[0126] In some embodiments of this disclosure, such as Figure 1 , Figure 9 as well as Figure 20As shown, the display device may have several function cards 50 on the side of the back panel 200 away from the cover plate 20. The function cards 50 may include any one or more of the following: system board 51, serial digital interface (SDI) video acquisition card, timing control circuit board 53, and constant current board 54.

[0127] In some embodiments of this disclosure, optionally, such as Figure 1 As shown, the timing control board can be set on the side of the back plate 200 away from the cover plate 20 and in the middle area of ​​the back plate 200. The timing control board can be connected to the circuit board of the display panel through a long flexible circuit board (FFC) line, so that the SDI video capture card 52 can be installed in the lower area of ​​the side of the back plate 200 away from the cover plate 20, so that the SDI video capture card 52 is set separately from the timing control board, avoiding the need to stack the SDI video capture card 52 on the side of the timing control board away from the back plate 200, thereby reducing the overall thickness of the display device.

[0128] In some embodiments of this disclosure, the distribution of each functional card 50 on the side of the back plate 200 away from the cover plate 20 can be planned in a coordinated manner. For example, other cards in the functional card 50 can also be set separately from the SDI video acquisition card 52 and the timing control board, so as to make reasonable use of the space on the side of the back plate 200 away from the cover plate 20 and reduce the overall thickness of the display device.

[0129] As an alternative implementation method, such as Figure 1 , Figure 19 as well as Figure 20 As shown, the assembly module also includes a protective cover 600, which is connected to the side of the rear plate 210 away from the cover plate 20 and forms a protective cavity between the protective cover 600 and the rear plate 210. The protective cover 600 is provided with a second transition clearance groove for avoiding the second transition part 312, and at least one functional card plate 50 is located in the protective cavity.

[0130] In some embodiments of this disclosure, such as Figure 1 , Figure 19 as well as Figure 20As shown, the assembly module also includes a protective cover 600. By connecting the protective cover 600 to the side of the back plate 210 away from the cover plate 20, a protective cavity is formed between the protective cover 600 and the back plate 210. The protective cavity can be used to arrange structures that need to be protected, such as circuit boards (PCBs), chip on film (COF311), and function cards 50, according to design requirements. Meanwhile, the protective cover 600 is provided with a second transition clearance groove for avoiding the first transition part 311. Thus, a protective cavity is formed between the protective cover 600 and the back plate 210 for the assembly of the back plate 200 and the outer frame 100 after the PCB, COF311 and the functional card plate 50. Since the protective cover 600 is provided with a second transition clearance groove for avoiding the second transition part 312, it is not necessary to remove the protective cover 600. The protective cover 600 is left on the back plate 200, so that the protective plate and the back plate 200 form an integrated protective structure to wrap and protect the PCB, COF311 and the functional card plate 50. Thus, the design of the protective cover 600 is compatible with both the shipment of the display module 30 and the shipment of the complete display device, realizing a compatible design and effectively reducing costs. At the same time, it can also protect the PCB and / or COF311 in real time during the assembly of the back plate 200 and the outer frame 100, improve the yield of the assembly process, and simplify the assembly steps.

[0131] As an optional implementation, the display module 30 includes a display panel, which is a liquid crystal display panel.

[0132] In some embodiments of this disclosure, such as Figure 1 , Figures 9 to 20 As shown, the display module 30 and the backlight module 40 can be disposed in a cavity between the rear plate 210 and the cover plate 20.

[0133] In some embodiments of this disclosure, when the display panel is a liquid crystal display panel, the display module 30 may also include an upper polarizing plate, a lower polarizing plate, a color filter, and other structures. The display module 30 may adopt the conventional liquid crystal display module 30 composition structure in the art, which will not be described in detail here.

[0134] In some embodiments of this disclosure, the display device can be assembled using an inverted method. During assembly, the cover plate 20 and the display module 30 are first bonded together with optically transparent adhesive. Then, the cover plate 20 and the display module 30 are assembled onto the outer frame 100. The cover plate 20 can then be placed face down on a worktable. Next, the backlight module 40 is assembled onto the back plate 200. Finally, the backlight module 40 and the back plate 200 are inverted onto the outer frame 100, and the back plate 200 is connected to the outer frame 100 via an adapter component 300, thus completing the assembly of the display device.
