[0002] Currently, large outdoor LED displays have various applications, such as advertising displays, rental displays, or commercial displays for business presentations. To display content from more angles or even from all directions, the screen is usually made larger, curved, or even 360-degree omnidirectional, becoming a large circular display screen.

[0003] Existing curved displays are typically constructed by splicing flat displays at angles. The inventors of this application have developed several products that use arc-shaped locks to connect two display cabinets to achieve curved displays. For example, invention publication number CN221960681U discloses a hollowed-out curved LED outdoor display, including a cabinet frame, LED display modules, and a power control box. The cabinet frame includes a frame body, an arc-shaped quick-lock assembly, and a drive module. The LED outdoor display is connected in an arc shape by either setting an arc-shaped quick-lock assembly on the frame body or by using a 45-degree left-side lock seat and a 45-degree right-side lock piece. Both arc-shaped connection methods can display a curved effect according to display needs.

[0004] Existing multi-sided display screens are also designed to provide 360-degree viewing without blind spots. For example, invention patent CN 222851068 discloses a can-shaped display screen. This can-shaped display screen includes a top cover, a base, a can frame, display modules, and casters. Both the top cover and the base adopt a can-like shape structure. The base has an internal cavity containing a power module and a control module, and casters are installed at the bottom of the base.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] Please see Figures 1 to 6 The illustration shows an LED display combination screen 200 and a curved display screen assembly cabinet frame 100 provided in an embodiment of the present invention. The LED display combination screen 200 includes multiple LED display modules and a curved display screen assembly cabinet frame 100. Figures 1-4 The display module in the example is an arc-shaped display module 20. The frame 100 for assembling this arc-shaped display includes a frame body 10, which houses electronic components. The frame body 10 includes a mounting panel 11, two side panels 12 extending obliquely from both sides of the mounting panel 11, and a top panel 13 and a bottom panel 14 extending correspondingly from the top and bottom edges of the mounting panel 11.

The electronic components are mounted on the mounting panel 11. The two side panels 12 are respectively connected to the side panel 12 of another curved display screen assembly cabinet frame 100 or the side of a flat display screen cabinet frame to form a cylindrical display combination screen 200a (e.g. Figure 5(as shown) or a multi-sided display combination screen with rounded corners 200b (such as) Figure 6 (As shown). It can be understood that the display module example in the illustration is an LED display module, but in actual use, it can also be applied to LCD display modules or other types of display modules.

[0027] In some preferred embodiments, the mounting panel 11, the two side panels 12, the top panel 13, and the bottom panel 14 are integrally formed. More preferably, the integrally formed structure is an aluminum alloy die-casting structure, which results in a high-precision box frame, particularly suitable for arc-shaped frame structures, and a more stable structure. The two side panels 12, the top panel 13, and the bottom panel 14 extend integrally from the corresponding edges of the mounting panel 11, which can also be referred to as integral die-casting.

[0028] Specifically, the top panel 13, the bottom panel 14, and the plurality of arc-shaped plates 15 are respectively arranged perpendicular to the mounting panel 11. The width of the mounting panel 11 in the horizontal direction is the chord of the corresponding arc among the arc-shaped plates 15, the arc-shaped top edge 132, and the arc-shaped bottom edge 142. That is, the mounting panel 11 is approximately the remaining part of a fan-shaped plate with the central triangle cut off, i.e., a panel enclosed by the chord, the arc, and two local radii. The extension direction of the two side panels 12 is the radial direction of the arc. For example, the side panels 12 are panels extending downward from the local radii. The top panel 13, the bottom panel 14, and the plurality of arc-shaped plates 15, together with the two side panels 12 and the mounting panel 11, form a vertically truncated fan-shaped cylinder with the central cone cut off. The inside of the fan-shaped cylinder has a cavity 110 to accommodate the electronic device.

[0029] In some preferred embodiments, each of the arc-shaped plates 15 and each of the side panels 12 is provided with a first magnetic accommodating element 151 at multiple positions facing the display screen; the plurality of first magnetic accommodating elements 151 on each arc-shaped plate 15 are arranged in an arc shape, and the two side panels 12 are provided with the first magnetic accommodating elements 151 at at least both ends of the arc of each arc-shaped plate 15; the plurality of first magnetic accommodating elements 151 on each arc-shaped plate 15 and the first magnetic accommodating elements 151 on the side panels 12 corresponding to the positions near the ends of the arc-shaped plates 15 are arranged in the same arc shape; each arc-shaped plate 15 has a vertical arc-shaped piece 156 at a predetermined distance from the arc edge 154, the arc of the arc-shaped piece is substantially parallel to the arc edge 154 of the corresponding arc-shaped plate 15, and the plurality of first magnetic accommodating elements 151 on the arc-shaped plate 15 are distributed and installed on the arc-shaped piece, preferably on the vertical arc-shaped piece 156. As shown in the figure, each vertical arc-shaped piece 156 is provided with three magnetic mounting slots 158, which are used to install three first magnetic components 151 respectively. Together with the two first magnetic components 151 installed on the left and right side panels 12, there are a total of 5 first magnetic components 151. The 5 first magnetic components 151 are arranged in an arc shape on the same horizontal plane.

[0030] In some specific embodiments, each arc-shaped plate 15 includes a vertical arc-shaped piece 156 and a horizontal arc-shaped piece 155; the horizontal arc-shaped piece 155 is perpendicular to the vertical arc-shaped piece 156 and perpendicular to the mounting panel 11; for example, in the illustrated orientation, the sheet-like surface of the horizontal arc-shaped piece 155 is horizontal, and the sheet-like surface of the vertical arc-shaped piece 156 is vertical. The vertical arc-shaped piece 156 has a predetermined width in the vertical direction; the horizontal arc-shaped piece 155 extends towards the display screen from the centerline of the vertical arc-shaped piece 156 in the horizontal direction; the vertical arc-shaped piece 156 extends integrally from the mounting panel 11; the vertical arc-shaped piece 156 is stamped from the mounting panel 11; the two ends of the vertical arc-shaped piece 156 are respectively connected to the two sides of the mounting panel 11 in the width direction and located inside the side panel 12; the vertical arc-shaped piece 156 protrudes from the mounting panel 11 in an arc or arch shape. In practical applications, the entire frame body 10 is die-cast from a single piece of aluminum alloy profile with a basically uniform thickness. Therefore, the top panel 13, the bottom panel 14, and the multiple curved plates 15 have a basically uniform thickness with the two side panels 12.

[0031] Preferably, the frame body 10 has a basically symmetrical structure from top to bottom, and more specifically, the frame body 10 has a basically symmetrical structure from left to right; the top panel 13 and the bottom panel 14 have a basically symmetrical structure from top to bottom; the top panel 13 and the bottom panel 14 are respectively provided with mounting holes 125, and the top panel 13 of one curved display screen assembly box frame 100 and the bottom panel 14 of another curved display screen assembly box frame 100 are assembled into one unit through the mounting holes 125 and fasteners 125a; thereby extending the dimensions in the longitudinal direction. The inner surfaces of the top panel 13 and the bottom panel 14 are respectively provided with a plurality of mounting parts 126, and the plurality of mounting heads of the plurality of mounting parts 126 are arranged in an arc shape, and a plurality of second magnetic absorbing pieces are installed through the plurality of mounting parts 126 and the plurality of second magnetic absorbing pieces are arranged in an arc shape to magnetically attract the corresponding arc-shaped display screen module 20. Therefore, the top panel 13, the bottom panel 14, and the arc-shaped plate 15 are evenly spaced from top to bottom, and the space between each pair corresponds to the position of a flexible screen 25. The first magnetic absorbing piece 151 and the second magnetic absorbing piece are attracted to the third magnetic absorbing piece on the arc-shaped display module 20 so as to be assembled into one piece.

[0032] Specifically, each of the side panels 12 has a mounting strip 127 on its inner surface, and the two mounting strips 127 on the two side panels 12 are on the same horizontal plane; the two mounting strips 127 are parallel to the mounting panel 11; each mounting strip 127 is equipped with a plurality of first magnetic absorbing pieces arranged from top to bottom; the outer edges of the two side panels 12, the arc edges 154 of each arc plate 15, the arc top edge 132, and the arc bottom edge 142 are respectively on the same arc circumferential surface; a plurality of side holes 18 are provided on the two side panels 12 at intervals; the side panels 12 of one arc display assembly cabinet frame are connected to the side panels 12 of another arc display assembly cabinet frame 100 (e.g., ...) through the plurality of side holes 18 and a plurality of fasteners 19. Figure 5 (as shown) or the side panel of the flat-screen display cabinet frame (such as Figure 6 As shown, they are assembled into one unit.

[0033] In some specific embodiments, the electronic device includes an electronic driver board 61 and a power supply 62, which are respectively mounted on an inner side of the mounting panel 11 facing the display screen; for example, the power supply 62 is mounted on the mounting panel 11 via a spring-loaded clamp. At least one arc-shaped plate 15 spans over the electronic driver board 61 and / or the power supply 62, that is, the arc-shaped plate 15 spans the two sides of the mounting panel 11, similar to an arched bridge, with sufficient space between the arc-shaped plate 15 and the mounting panel 11 to accommodate the electronic device.

[0034] In some specific embodiments, the frame body 10 is equipped with at least one bottom shell 28; as shown in the figure, multiple bottom shells are used, and each bottom shell 28 corresponds to a flexible screen 25. Of course, in some embodiments, multiple flexible screens 25 can be installed on one bottom shell at the same time. The bottom shell 28 is arc-shaped with a predetermined curvature; for example, the bottom shell 28 is tile-shaped; the bottom shell 28 is preferably a rigid PC plastic shell, combined with the frame body which is an integral die-cast aluminum alloy structure, so that the arc-shaped LED display combination screen 200 is not easily deformed and can adapt to various outdoor high temperature, humidity or climate environments. Specifically, the bottom shell 28 has one or more arc-shaped grooves 33. When multiple bottom shells 28 are used, each bottom shell 28 has arc-shaped grooves 33 on its top edge and bottom edge respectively. When a single bottom shell 28 is used, the bottom shell 28 has arc-shaped grooves 33 on its top edge, bottom edge and multiple arc-shaped grooves 33 in the middle position respectively. The space between two adjacent arc-shaped grooves 33 corresponds to a curved flexible LED display screen, i.e., a flexible screen 25. The curved flexible LED display screen is mounted on the outer surface of the bottom shell 28 away from the frame body 10. The arc-shaped top edge 132 of the top panel 13, the arc-shaped bottom edge 142 of the bottom panel 14 and the arc-shaped edge 154 of each arc plate 15 are respectively connected to the corresponding arc-shaped grooves 33. The bottom shell 28 has multiple third magnetic elements 133 on its inner surface facing the mounting panel 11. These third magnetic elements 133 are attracted to corresponding first magnetic elements 151 or second magnetic elements, allowing the bottom shell 28 to be attached to the frame body 10. Preferably, the radius of curvature is π / 4. Therefore, by splicing four frame bodies 10 together, four sets of flexible screens 25 are spliced ​​together to form a cylindrical LED display screen, such as... Figure 5 As shown, the cylindrical LED display combination screen consists of an inner square and an outer circle, with the screen surface being a circular surface.

[0035] This invention also provides an arc-shaped display unit, namely... Figures 1 to 4The example shows the portion with a display screen. The curved display unit includes multiple display screens and a cabinet frame; each display screen is a curved flexible display screen, and multiple curved flexible display screens are installed side by side on a rigid base shell with a fixed curvature. The cabinet frame is the curved display screen assembly cabinet frame 100 as described above. The curved flexible display screen is preferably the aforementioned curved flexible LED display screen, i.e., flexible screen 25. The rigid base shell is the aforementioned base shell 28. The rigid base shell 28 is mounted on the curved display screen assembly cabinet frame 100. The curved flexible display screen, the rigid base shell with a fixed curvature, and the curved display screen assembly cabinet frame are all integrated with the same curvature. This close fit and seamless construction result in a compact structure. Furthermore, the rigid base shell 25 shapes the curved flexible display screen, solving the problem that the flexible screen 25 is prone to warping or deformation after prolonged use. It also solves the problem that multiple curved flexible display screens are difficult to align and that the curvature is difficult to maintain.

[0036] In some preferred embodiments, the plurality of LED display modules include one or more arc-shaped LED display modules 20, each arc-shaped LED display module 20 including at least one flexible screen 25 and being arc-shaped. The cabinet frame includes a straight cabinet frame 51 and / or an arc-shaped cabinet frame. The arc-shaped cabinet frame is the arc-shaped display assembly cabinet frame 100 as described above. Each arc-shaped LED display module 20 is mounted on the arc-shaped display assembly cabinet frame 100 via a bottom shell 28. The plurality of arc-shaped LED display modules 20 are sequentially assembled into a cylindrical LED display combination screen 200 via the arc-shaped display assembly cabinet frame 100, or the plurality of LED display modules are assembled into an arc-shaped LED display combination screen 200 with rounded corners via at least one arc-shaped cabinet frame and two or more straight cabinet frames 51. Figure 5 As shown, this is an LED display combination screen 200a composed of four arc-shaped display units assembled into a regular cylindrical surface.

[0037] Specifically, if Figure 5 and Figure 6 As shown, the box frame includes a straight box frame and / or an arc-shaped box frame; the arc-shaped box frame is as follows: Figures 1 to 4 The aforementioned curved display screen assembly cabinet frame 100, wherein each of the aforementioned arc-shaped LED display screen modules 20 is mounted on the curved display screen assembly cabinet frame 100 via a bottom shell 28. For example... Figure 5 As shown, multiple arc-shaped LED display modules 20 are sequentially assembled into a cylindrical LED display combination screen via the arc-shaped display assembly cabinet frame 100. Alternatively, in another embodiment, as... Figure 6As shown, multiple LED display modules are assembled into an arc-shaped LED display combination screen 200b with rounded corners by splicing at least one curved display assembly cabinet frame 100 and two or more straight cabinet frames 102. The straight cabinet frame 102 is equipped with a flat display module. Figure 6 This product, which displays a single corner splicing structure, can be assembled into a large LED combination screen with four or more sides in practical applications. For example, based on a 250*125mm curved flexible screen, the main body of the cabinet frame is a 250*500mm die-cast cabinet, suitable for various curved corner display screen projects with 500mm as the base unit. For example, four cabinet frames can form a complete circle with a circumference of 1m. This product in this embodiment can be ceiling-mounted, table-mounted, and customized for various irregularly shaped fixed curvature commercial displays.

[0038] In the aforementioned LED display combination screen 200, curved display unit, and curved display screen assembly cabinet frame 100, the top panel 13, bottom panel 14, and side panel 12 each have curved edges with a consistent curvature. The curvature of the curve matches the desired display surface and is tightly integrated with the curved display module, resulting in a compact structure and higher installation precision. Furthermore, each panel is integrally molded, further improving the cabinet assembly precision. Moreover, this fan-shaped frame structure allows for the assembly of different curved combination screens or display combination screens combining curved and flat surfaces, making assembly more flexible and versatile, applicable to more application scenarios and product styles. For example, it can assemble regular cylindrical display faces or four-sided enclosed display combination screens with rounded corners, suitable for rental LED displays, commercial displays, and other products. In addition, the magnetic assembly of the frame body and display module allows for front and rear maintenance of each component, enabling both hanging and table mounting, thus broadening the application scenarios.
