Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application.

[0033] In the embodiment, the LED display screen comprises a first box body 10, a first display module 20, a second box body 30 and a second display module 40. The front surface of the first box body 10 is a first front surface. The first display module 20 is arranged on the first front surface, and a first splicing inclined surface 211 is arranged on the edge of the first display module 20. The second box body 30 is connected with the first box body 10, and the front surface of the second box body 30 is a second front surface. The second display module 40 is arranged on the second front surface, and a second splicing inclined surface 411 is arranged on the edge of the second display module 40, and the second splicing inclined surface 411 and the first splicing inclined surface 211 are oppositely arranged. The first splicing inclined surface 211 and the second splicing inclined surface 411 are arranged in close contact. The first box body 10 and the second box body 30 are integrally formed. When a first included angle is formed between the first front surface and the second front surface, and the first included angle is greater than 0 degrees and less than 180 degrees, the first splicing inclined surface 211 is gradually arranged to be inclined to the inside of the first box body 10 in the direction from the front side of the first box body 10 to the rear side of the first box body 10; and the second splicing inclined surface 411 is gradually arranged to be inclined to the inside of the second box body 30 in the direction from the front side of the second box body 30 to the rear side of the second box body 30. Alternatively, when a second included angle is formed between the first front surface and the second front surface, and the second included angle is greater than 180 degrees and less than 360 degrees, the first splicing inclined surface 211 is gradually arranged to be inclined to the outside of the first box body 10 in the direction from the front side of the first box body 10 to the rear side of the first box body 10; and the second splicing inclined surface 411 is gradually arranged to be inclined to the outside of the second box body 30 in the direction from the front side of the second box body 30 to the rear side of the second box body 30.

[0034] In this way, the first cabinet 10 and the second cabinet 30 are arranged as an integral molded part, errors caused by the need to splice the first cabinet 10 and the second cabinet 30 are avoided, and the gap between the first display module 20 and the second display module 40 is reduced. Through the arrangement of the first splicing inclined surface 211 and the second splicing inclined surface 411, the first display module 20 and the second display module 40 can be closely fitted when spliced, the gap between the first display module 20 and the second display module 40 is further reduced, the gap at the splicing position of the corner is further reduced, the dark seam on the display surface is reduced, and the display effect is improved. Therefore, the technical scheme of the present application effectively solves the problem in the related art that a larger gap is easily generated at the splicing position of the corner, affecting the display effect. When the first included angle is greater than 0 degrees and less than 180 degrees, the first splicing inclined surface 211 is arranged to gradually incline to the inside of the first cabinet 10 in the direction from the front side of the first cabinet 10 to the back side of the first cabinet 10; and the second splicing inclined surface 411 is arranged to gradually incline to the inside of the second cabinet 30 in the direction from the front side of the second cabinet 30 to the back side of the second cabinet 30. In this way, when the first included angle is greater than 0 degrees and less than 180 degrees, the display surface of the LED display screen is an outward convex surface, that is, the display surface of the LED display screen protrudes towards the observer, and the inclination direction of the first splicing inclined surface 211 and the second splicing inclined surface 411 facilitates the closer fitting of the first display module 20 and the second display module 40 when spliced, thereby improving the display effect. Alternatively, when the second included angle is greater than 180 degrees and less than 360 degrees, the first splicing inclined surface 211 is arranged to gradually incline to the outside of the first cabinet 10 in the direction from the front side of the first cabinet 10 to the back side of the first cabinet 10; and the second splicing inclined surface 411 is arranged to gradually incline to the outside of the second cabinet 30 in the direction from the front side of the second cabinet 30 to the back side of the second cabinet 30. In this way, when the second included angle is greater than 180 degrees and less than 360 degrees, the display surface of the LED display screen is an inward concave surface, that is, the display surface of the LED display screen is recessed away from the observer, and the inclination direction of the first splicing inclined surface 211 and the second splicing inclined surface 411 facilitates the closer fitting of the first display module 20 and the second display module 40 when spliced, thereby improving the display effect.

[0035] It should be noted that the front side of the first cabinet 10 refers to the side on which the first display module 20 is arranged, and the first front surface refers to the surface connected with the first display module 20. The front side of the second cabinet 30 refers to the side on which the second display module 40 is arranged, and the second front surface refers to the surface connected with the second display module 40.

[0036] As Figures 1 to 3As shown, the first display module 20 comprises a first rear shell 21 and a first lamp panel 22 arranged on the first rear shell 21, and the first splicing bevel 211 is arranged on the side edge of the first rear shell 21. By arranging the first splicing bevel 211 on the side edge of the first rear shell 21, the splicing gap between the first display module 20 and the second display module 40 can be effectively reduced, and the display effect is improved. Moreover, arranging the first splicing bevel 211 on the side edge of the first rear shell 21 facilitates the processing of the first display module 20, and the processing cost is relatively low.

[0037] As shown in the first display module 20, Figures 1 to 3 The first rear shell 21 is rectangular, the first rear shell 21 has four side surfaces, the first splicing bevel 211 is a plurality of, and the number of the first splicing bevel 211 is less than or equal to four, and each first splicing bevel 211 is arranged on one side edge of the first rear shell 21. This design enables the first display module 20 to be seamlessly connected from multiple directions when splicing, thereby improving the flexibility and adaptability of the splicing of the first display module 20.

[0038] In this embodiment, the number of the first splicing bevel 211 is four, so that the first display module 20 can be seamlessly spliced in the direction of the four side edges of the first rear shell 21, thereby improving the splicing flexibility of the first display module 20. Moreover, by arranging the four first splicing bevels 211, one of the four first splicing bevels 211 can be attached to the second splicing bevel 411, so that the operator does not need to distinguish the front and back of the first display module 20 when installing the first display module 20, the operation is simple, and the assembly is facilitated. The inclination angles of the two oppositely arranged first splicing bevels 211 are the same.

[0039] In other embodiments, the number of the first splicing bevel 211 is two, and the two first splicing bevels 211 are oppositely arranged on the two oppositely arranged side surfaces of the first rear shell 21. In this way, one of the two oppositely arranged first splicing bevels 211 can be attached to the second splicing bevel 411, so that the operator does not need to distinguish the front and back of the first display module 20 when installing the first display module 20, the operation is simple, and the assembly is facilitated. The inclination angles of the two oppositely arranged first splicing bevels 211 are the same.

[0040] In other embodiments, the number of the first splicing bevel 211 is three.

[0041] As shown in the first display module 20, Figures 1 to 3As shown, the first front surface and the second front surface are perpendicular to each other. A third angle is formed between the first splicing inclined surface 211 and the front-rear direction of the first housing 10. A fourth angle is formed between the second splicing inclined surface 411 and the front-rear direction of the second housing 30. The sum of the third and fourth angles is 90°. This arrangement allows the corner display surface formed by splicing the first display module 20 and the second display module 40 to better match the angle between the first and second front surfaces, thereby reducing the gap between the first display module 20 and the second display module 40 and improving the display effect.

[0042] In this embodiment, the third included angle and the fourth included angle are the same, both being 45°.

[0043] like Figures 1 to 3 As shown, the second display module 40 includes a second rear shell 41 and a second lamp panel 42 disposed on the second rear shell 41. A second splicing bevel 411 is disposed on the side edge of the second rear shell 41. By disposing the second splicing bevel 411 on the side edge of the second rear shell 41, the splicing gap between the first display module 20 and the second display module 40 can be effectively reduced, improving the display effect. Furthermore, disposing the second splicing bevel 411 on the side edge of the second rear shell 41 facilitates the processing of the second display module 40, resulting in lower processing costs. The second rear shell 41 is rectangular, with four side surfaces and multiple second splicing bevels 411, with the number of bevels 411 being less than or equal to four. Each second splicing bevel 411 is disposed on one side edge of the second rear shell 41. This design allows the second display module 40 to be seamlessly connected from multiple directions during splicing, improving the flexibility and adaptability of splicing the second display module 40.

[0044] In this embodiment, four second splicing bevels 411 are used, enabling seamless splicing of the second display module 40 along the four side edges of the second rear shell 41, thus improving the splicing flexibility of the second display module 40. Furthermore, the four second splicing bevels 411 allow one of them to fit snugly against the first splicing bevel 211, eliminating the need for operators to distinguish the top and bottom of the second display module 40 during installation, simplifying the operation and facilitating assembly. The tilt angles of two oppositely positioned second splicing bevels 411 are the same.

[0045] In other embodiments, there are two second splicing bevels 411, which are disposed opposite to each other on two opposite side surfaces of the second rear shell 41. One of these opposing second splicing bevels 411 can fit into the first splicing bevel 211, eliminating the need for operators to distinguish the top and bottom of the second display module 40 during installation, simplifying the operation and facilitating assembly. The two opposing second splicing bevels 411 have the same inclination angle.

[0046] In other embodiments, the number of second splicing ramps 411 is three.

[0047] like Figures 1 to 3 As shown, the first front surface includes a first region and a second region. The first region is connected to the second front surface, and the first region separates the second region and the second front surface. The LED display screen also includes a third display module 50 disposed on the second region. The first display module 20 is disposed on the first region, and the display area of ​​the third display module 50 is larger than that of the first display module 20. This makes the display area of ​​the first display module 20 disposed on the first region connected to the second front surface smaller, which facilitates the processing of the first splicing bevel 211, reduces processing costs, and also facilitates the operator's operation of attaching the first splicing bevel 211 to the second splicing bevel 411. It also makes the display area of ​​the third display module 50, which does not need to be spliced ​​with the second display module 40, larger, improving the versatility of the third display module 50, facilitating reuse, and reducing costs. The second front surface includes a third region and a fourth region. The third region is connected to the first front surface, and the third region separates the fourth region and the first front surface. The LED display screen also includes a fourth display module 60 disposed on the fourth region. The second display module 40 is disposed on the third region. The display area of ​​the fourth display module 60 is larger than that of the second display module 40. This results in a smaller display area for the second display module 40, which is located in the third region connected to the first front surface. This facilitates the processing of the second splicing bevel 411, reduces processing costs, and also simplifies the operation of attaching the first splicing bevel 211 to the second splicing bevel 411. Furthermore, it allows for a larger display area for the fourth display module 60, which does not require splicing with the first display module 20. This improves the versatility of the fourth display module 60, makes it easier to reuse, and reduces costs.

[0048] In the embodiment, the first display modules 20 are 6, and the third display modules 50 are 24. The second display modules 40 are 6, and the fourth display modules 60 are 24. The third display modules 50 and the fourth display modules 60 are general modules, which reduces the processing cost. The first splicing bevel extends in the up-down direction, and the length of the first display module in the up-down direction is greater than the length of the third display module in the up-down direction. The second splicing bevel extends in the up-down direction, and the length of the second display module in the up-down direction is greater than the length of the fourth display module in the up-down direction.

[0049] In other embodiments, the first front surface includes a first region and a second region, the first region is connected with the second front surface, and the first region separates the second region and the second front surface. The LED display screen further includes a third display module 50 arranged on the second region.

The LED display screen further includes a fourth display module 60 arranged on the fourth region. The second display module 40 is arranged on the third region. The display area of the fourth display module 60 is greater than the display area of the second display module 40.

[0050] As shown in Figure 4 The rear side wall of the first cabinet 10 is provided with a through hole 71, and a baffle 72 is detachably connected in the through hole 71. When the baffle 72 is disconnected from the through hole 71, the through hole 71 is used to pass the lead wire. This detachable baffle 72 design not only improves the waterproof and dustproof performance of the LED display screen, but also facilitates the passage and maintenance of the lead wire. When the lead wire is not needed to be passed, the baffle 72 can block dust and rain. When the lead wire needs to be passed, the baffle 72 is disconnected from the through hole 71, so that the lead wire can pass through the through hole 71.

[0051] It should be noted that "detachable connection" means that the baffle 72 can be fixedly connected in the through hole 71 without external force; when the operator knocks the baffle 72, the baffle 72 can be disconnected from the through hole 71, so that the baffle 72 falls off, so that the through hole 71 can penetrate the front and rear surfaces of the rear side wall of the first cabinet 10.

[0052] As shown in Figure 4As shown, the first box body 10 is provided with a containing cavity, and a drain box 80 is arranged on the rear side wall of the first box body 10 and located in the containing cavity. A through hole 71 is arranged on the side wall of the drain box 80, and the opening of the drain box 80 is upwardly arranged. The arrangement of the drain box 80 further enhances the waterproof and dustproof capability of the LED display screen, can effectively drain the water entering from the through hole 71, and prevent the water from entering the containing cavity from the through hole 71, thereby reducing the possibility of short circuit of the internal circuit due to water entering and ensuring the long-term stable operation of the LED display screen.

[0053] As shown in the drawings, Figure 4 The upper surface of the bottom wall of the drain box 80 is flush with the lower hole wall of the through hole 71. In this way, the water entering from the through hole 71 can be more smoothly drained, and the possibility of water accumulation on the bottom wall of the drain box 80 is reduced. The side wall of the drain box 80 is provided with a water guide slope 81, and the water guide slope 81 gradually approaches the through hole 71 in the direction from the outside of the drain box 80 to the inside of the drain box 80. The arrangement of the water guide slope 81 can guide the water in the drain box 80, so that the water in the drain box 80 can be more quickly drained, avoiding the accumulation of water in the containing cavity and prolonging the service life.

[0054] In other embodiments, the upper surface of the bottom wall of the drain box 80 is flush with the lower hole wall of the through hole 71. Alternatively, the side wall of the drain box 80 is provided with a water guide slope 81, and the water guide slope 81 gradually approaches the through hole 71 in the direction from the outside of the drain box 80 to the inside of the drain box 80.
