[0035] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0036] According to one aspect of this application, an LED display device is provided, such as... Figures 1 to 4 As shown, an embodiment of the LED display device includes: multiple display components 10, an arc-shaped display component 20, a first corner connecting piece 30, and a second corner connecting piece. The multiple display components 10 include a first display component 11 and a second display component 12 spliced ​​together. At least one corner of the rear portion of the first display component 11 is provided with a first connecting surface 111, and at least one corner of the rear portion of the second display component 12 is provided with a second connecting surface. The first display component 11 is spliced ​​to the second display component 12 at an angle via the arc-shaped display component 20, so that the display surface of the first display component 11 transitions to the display surface of the second display component 12 through the arc-shaped display surface of the arc-shaped display component 20. Two adjacent rear corners of the arc-shaped display component 20 are provided with a first recess 21 and a second recess 22. The first recess 21 includes a third connecting surface 211 flush with the first connecting surface 111, and the second recess 22 includes a fourth connecting surface 221 flush with the second connecting surface. The first corner connecting piece 30 is connected to the first connecting surface 111 and the third connecting surface 211, and the second corner connecting piece is connected to the second connecting surface and the fourth connecting surface 221, so as to splice the first display component 11, the arc-shaped display component 20 and the second display component 12 together.

[0037] The technical solution of the embodiment of the LED display device, since the first corner connecting piece 30 is connected to the first connecting surface 111 and the third connecting surface 211 which are flush, and the second corner connecting piece is connected to the second connecting surface and the fourth connecting surface 221 which are flush, can reduce the installation error between the first display component 11 and the curved display component 20, and between the second display component 12 and the curved display component 20. After the first display component 11, the curved display component 20 and the second display component 12 are spliced ​​together, the display effect of the LED display device can be effectively improved. Therefore, the technical solution of the embodiment of the LED display device effectively solves the problem of poor display effect of LED display devices in related technologies.

[0038] like Figures 1 to 4 As shown, there are multiple curved display components 20, first display components 11, and second display components 12. Multiple curved display components 20 are connected sequentially along the vertical direction of one of the curved display components 20; multiple first display components 11 are connected sequentially along the vertical direction of one of the first display components 11; and multiple second display components 12 are connected sequentially along the vertical direction of one of the second display components 12. At the remaining two adjacent corners of the rear portion of each curved display component 20, a third recess 23 and a fourth recess 24 are provided. The third recess 23 of two adjacent curved display components 20 communicates with the first recess 21, and at least a portion of the first corner connecting piece 30 is located within the third recess 23 and the first recess 21. The fourth recess 24 of two adjacent curved display components 20 communicates with the second recess 22, and at least a portion of the second corner connecting piece is located within the fourth recess 24 and the second recess 22. By sequentially connecting the aforementioned multiple arc-shaped display components 20, multiple first display components 11, and multiple second display components 12, a continuous arc-shaped display effect is achieved, improving the overall visual experience of the LED display device. Furthermore, the connection between the first corner connecting piece 30 and the second corner connecting piece is made more stable, enhancing the structural stability of the LED display device.

[0039] The thickness at the four rear corners of the curved display component 20 is the same as the thickness at the rear corners of the first display component 11 and the second display component 12. This allows the use of conventional connecting pieces without the need for custom-made irregular connecting pieces, thus ensuring the splicing accuracy between the first display component 11 and the curved display component 20, and between the second display component 12 and the curved display component 20. This ensures that there are no gaps between the display surfaces of the first display component 11, the curved display surface of the curved display component 20, and the display surface of the second display component 12, thereby guaranteeing installation accuracy and easily ensuring the display effect of the LED display device.

[0040] like Figures 1 to 4As shown, the first connecting surfaces 111 are located at the four corners of the rear of the first display component 11. The third recess 23 includes a fifth connecting surface 231 flush with one of the adjacent first connecting surfaces 111. The first corner connecting piece 30 connects to two adjacent first connecting surfaces 111, the third connecting surface 211, and the fifth connecting surface 231 to splice multiple first display components 11 and multiple curved display components 20 together. The flush design of the first connecting surfaces 111 and the fifth connecting surfaces 231 ensures precise splicing between the first display components 11 and the curved display components 20, reduces screen brightness differences and pixel misalignment caused by uneven connecting surfaces, and improves the uniformity and consistency of the displayed image of the LED display device.

[0041] like Figures 1 to 4 As shown, the second connecting surfaces are located at the four corners of the rear of the second display component 12. The fourth recess 24 includes a sixth connecting surface 241 flush with one of the adjacent second connecting surfaces. The second corner connecting pieces connect to the two adjacent second connecting surfaces, the fourth connecting surface 221, and the sixth connecting surface 241 to splice the multiple second display components 12 and the multiple curved display components 20 together. The flush design of the second connecting surface and the sixth connecting surface 241 reduces the installation error between the second display component 12 and the curved display component 20, further ensuring the overall display quality and visual effect after splicing the multiple curved display components 20, the multiple first display components 11, and the multiple second display components 12.

[0042] like Figures 3 to 7 As shown, the curved display assembly 20 includes a curved display screen 25 and a curved housing 26 disposed at the rear of the curved display screen 25. A first recess 21 and a second recess 22 are both located at two adjacent corners of the rear of the curved housing 26. The design of the curved housing 26 supports the physical shape of the curved display screen 25, enhancing structural strength and ensuring stable display performance of the curved display screen 25 under bending conditions.

[0043] like Figures 3 to 7As shown, the curved box body 26 includes a curved frame 261, a top plate 262, a bottom plate 263, a first side plate 264, a second side plate 265, and a rear cover 266. The top plate 262 is connected to the top of the curved frame 261, the bottom plate 263 is connected to the bottom of the curved frame 261, the first side plate 264 and the second side plate 265 are respectively connected to the two sides of the curved frame 261, and the rear cover 266 covers the rear of the curved frame 261. At least one corner of the rear of the rear cover 266 is provided with a front concave plate portion 40. A first latch 267 is provided on the side of the top plate 262, and a second latch 268 is provided on the side of the first side plate 264. A portion of the front concave plate portion 40 is attached to the side wall of the first latch 267. The first latch 267, the front concave plate portion 40, and the second latch 268 together form a first recess 21. Through the specific configuration of the above-mentioned curved box 26 structure, a stable curved box 26 is formed. The front concave plate 40 on the rear cover 266 works together with the first latch 267 of the top plate 262 and the second latch 268 of the first side plate 264 to optimize the alignment and fixation between the first display component 11 and the curved display component 20 and between the second display component 12 and the curved display component 20. This avoids gaps and misalignments under the traditional corner connecting frame method and enhances the reliability of the LED display device.

[0044] Specifically, the upper end of the first side plate 264 is inserted into and connected to the first end of the top plate 262, and is fixedly connected by a first L-shaped connector. The upper end of the second side plate 265 is inserted into and connected to the second end of the top plate 262, and is fixedly connected by a second L-shaped connector. The lower end of the first side plate 264 is inserted into and connected to the first end of the bottom plate 263, and is fixedly connected by a third L-shaped connector. The lower end of the second side plate 265 is inserted into and connected to the second end of the bottom plate 263, and is fixedly connected by a fourth L-shaped connector. This ensures the installation accuracy of the curved box 26. The aforementioned fixed connections are preferably screw connections.

[0045] The curved frame 261 includes two side beams and multiple curved plates disposed on the front side of the two side beams, with the multiple curved plates spaced apart in the vertical direction. The front surfaces of the multiple curved plates together form a curved mounting surface for mounting the curved display screen 25 on the curved mounting surface.

[0046] like Figures 3 to 7As shown, the top plate 262 and the first side plate 264 are connected by corner fasteners 50. The front concave plate portion 40 includes a folding plate 41 that is folded and connected to the rear plate 269 of the rear cover 266, a sealing plate 42 connecting the folding plate 41 and the rear plate 269, and a baffle 43. The folding plate 41 folds towards the curved display screen 25, forming a trapezoidal notch between the folding plate 41, the rear plate 269, and the second latch 268. The sealing plate 42 seals the trapezoidal notch. The baffle 43 is connected to the folding plate 41 and the sealing plate 42, and is located on the rear side of the corner fastener 50 and fits snugly against the corner fastener 50. The use of the corner fastener 50 simplifies the assembly process and improves production efficiency. The combined design of the folding plate 41, the sealing plate 42, and the baffle 43 provides a connection position for the fastener 60, ensuring the stable installation of the first corner connecting piece 30. On the other hand, the presence of the sealing plate 42 prevents external substances from entering the display, protects electronic components from damage, and improves the waterproof and dustproof rating.

[0047] Specifically, the sealing plate 42 is welded to the connecting folding plate 41 and the rear plate 269, and the baffle 43 is welded to the folding plate 41 and the sealing plate 42.

[0048] like Figures 3 to 7 As shown, the first corner connecting piece 30 is provided with a first connecting hole 31. The corner fixing member 50 is provided with a second connecting hole 51. The fastener 60 passes through the first connecting hole 31 and is connected to the second connecting hole 51 to fix the first corner connecting piece 30 on the first connecting surface 111 and the third connecting surface 211. The fastening method of the first corner connecting piece 30 and the corner fixing member 50 by the fastener 60 ensures the stability of the connection, while simplifying the disassembly and assembly process and reducing maintenance costs.

[0049] like Figures 3 to 7 As shown, the baffle 43 includes a first plate segment 432 connected to the folding plate 41 and a second plate segment 433 connected to the sealing plate 42. The included angle region between the first plate segment 432 and the second plate segment 433 allows the fastener 60 to pass through. The design of the included angle region between the first plate segment 432 and the second plate segment 433 of the baffle 43 provides clear clearance for the fastener 60 to pass through, ensuring that the fastener can pass smoothly during installation without being obstructed by other structures, thereby improving assembly speed and accuracy.

[0050] like Figures 5 to 8As shown, the corner fastener 50 includes a first segment 52, a second segment 53, and a third segment 54. The first segment 52 is connected to the second segment 53 at an angle, the second segment 53 is connected to the third segment 54 at an angle, and the third segment 54 is connected to the first segment 52 at an angle. The first segment 52 is fixedly connected to the top plate 262, the second segment 53 is fixedly connected to the first side plate 264, and the third segment 54 is fitted to the baffle 43. This multi-faceted contact design of the corner fastener 50 increases the contact area of ​​the connection, thereby enhancing the connection strength between the top plate 262, the first side plate 264, and the first corner connecting piece 30. Even under heavy loads, the structural integrity of the curved box 26 can be maintained.

[0051] like Figures 1 to 3 As shown, both the first display component 11 and the second display component 12 include a flat panel display screen 112 and a flat cabinet 113 disposed at the rear of the flat panel display screen 112.
