[0003] In related technologies, irregularly shaped screens, such as circular screens and spherical screens, are usually designed from LED grid screens. However, in order to adapt to the specific slope of the curved or beveled edges, each carrier board used to arrange the LED beads needs to be customized, which is not conducive to improving production efficiency. Utility Model Content

[0004] The main purpose of this utility model is to propose a carrier board assembly, an LED module, a circular screen, and a spherical screen. The aim is to design a carrier board assembly that can be configured or spliced ​​to form irregularly shaped screens in terms of appearance, so as to improve production efficiency.

[0005] To achieve the above objectives, this utility model proposes a carrier plate assembly, which includes a plurality of first strips and a plurality of second strips. The plurality of first strips are spaced apart along a first direction, and the plurality of second strips are spaced apart along a second direction perpendicular to the first direction and intersect the first strips to form a mesh structure with a plurality of through holes. One side of the mesh structure is defined by a plurality of continuous ends to form a first virtual boundary. The first virtual boundary is inclined relative to the second direction and the angle between the first virtual boundary and the second direction is not equal to 90°.

[0006] In one embodiment, the first virtual boundary is an arc edge or a slanted edge.

[0007] In one embodiment, the lengths of at least two of the first strips increase sequentially along a first direction, and the lengths of at least two of the second strips decrease sequentially along a second direction; the ends of the at least two first strips with increasing lengths and the ends of the at least two second strips with decreasing lengths together define the first virtual boundary.

[0008] In one embodiment, one side of the mesh structure is further defined by a plurality of consecutive ends to form a second virtual boundary, the second virtual boundary being perpendicular to the second direction. And / or, one side of the mesh structure is further defined by a plurality of consecutive ends to form a third virtual boundary, the third virtual boundary being parallel to the second direction.

[0009] In one embodiment, the carrier plate assembly is formed by splicing together multiple sub-carrier plates, each of the sub-carrier plates including a first sub-strip and a second sub-strip arranged in a cross manner to be spliced ​​together to form the first strip and the second strip.

[0010] In one embodiment, the first sub-strip and / or the second sub-strip are provided with splicing holes. The carrier plate assembly further includes a connector, and the two ends of the connector are respectively provided with first connecting holes. The first connecting holes and the splicing holes of the two sub-carrier plates are respectively connected by fasteners to connect the two sub-carrier plates.

[0011] In one embodiment, the carrier assembly is divided into an installation area and a display area. A power supply interface is provided on one side of the installation area. The display area includes a first strip and a second strip, with the second strip formed on one side of the installation area.

[0012] In one embodiment, the first strip and / or the second strip are provided with a second connecting hole extending through the thickness direction. And / or, a reinforcing portion is provided circumferentially at the connection between the first strip and the second strip.

[0013] This utility model also proposes an LED module, which includes a frame assembly, a plurality of LED beads, and a carrier board assembly as described above. The frame assembly extends along the periphery of the carrier board assembly for mounting the carrier board assembly. The plurality of LED beads are arranged on the side of the carrier board assembly away from the frame assembly and are located in the solid area between each of the through holes.

[0014] In one embodiment, the first virtual boundary is an arc edge, and the frame assembly includes a first side beam, a second side beam, and an arc beam connected end to end to enclose and form a fan-shaped frame, and the carrier plate assembly is installed on one side of the fan-shaped frame.

[0015] This utility model also proposes a circular screen, which includes multiple LED modules as described above, wherein each LED module is a fan-shaped screen, and the radial edges of two adjacent fan-shaped screens are spliced ​​together.

[0016] This utility model also proposes a spherical screen, which includes a circular screen as described above and multiple polygonal screens. Each polygonal screen has a beveled edge on both sides, and the beveled edges of two adjacent polygonal screens are spliced ​​together to form a spherical outer arc surface. The periphery of the circular screen is spliced ​​with the top edges of the multiple polygonal screens to form a dome.

[0017] In the technical solution of this utility model, the first and second strips intersect to form through holes, and the arrangement density of the through holes can be adjusted to meet different light transmittance requirements. It is worth noting that by adjusting the length and intersection angle of the first and second strips, the first virtual boundary can form an arc edge or a beveled edge to construct an arc-shaped screen or a beveled screen, or to adapt to the edge requirements of irregularly shaped screens such as circles and spheres. Therefore, since the first virtual boundary is formed as a whole through a grid structure, it avoids the need for customization of each carrier plate, similar to LED grid screens, thereby improving production efficiency.

[0025] LED (Light Emitting Diode) displays are display devices made of LEDs. By controlling the brightness and color combination of LEDs, they can display text, images, videos, and other content, and are widely used in commercial window displays and other fields.

[0026] In related technologies, irregularly shaped screens, such as circular and spherical screens, are typically designed using LED grid screens. However, to accommodate the specific slope of curved or beveled edges, each carrier board used to arrange the LED beads needs to be customized, which hinders production efficiency. Furthermore, the existing LED module carrier boards have rectangular edges, resulting in poor display effects when forming or splicing irregularly shaped screens.

[0027] To address the aforementioned issues, this utility model proposes a carrier plate assembly 1, which aims to design a carrier plate assembly 1 that can be configured or spliced ​​to form an irregularly shaped screen in terms of appearance, thereby improving production efficiency.

[0028] Reference Figures 1 to 12 or refer to Figure 13 In one embodiment of the present invention, the carrier plate assembly 1 includes a plurality of first strips 11 and a plurality of second strips 13. The plurality of first strips 11 are spaced apart along a first direction, and the plurality of second strips 13 are spaced apart along a second direction perpendicular to the first direction and intersect the first strips 11 to form a grid structure with a plurality of through holes 181. One side of the mesh structure is defined by a plurality of continuous ends 12 to form a first virtual boundary 161, the first virtual boundary 161 being inclined relative to the second direction and having an angle with the second direction not equal to 90°.

[0029] Typically, the plate is filled with arrayed through holes 181. The horizontal and vertical solid areas between each through hole 181 can be regarded as the first body 11 and the second body 13, respectively. The first body 11 and the second body 13 are integrally molded.

[0030] The first virtual boundary 161 can be an arc boundary, a straight line boundary, a segmented polygonal line boundary, or a boundary with gradually changing curvature, etc., to meet the boundary requirements of various irregularly shaped screens. One side of the mesh structure can be formed by cutting off each end 12, thereby forming the first virtual boundary 161.

[0031] In the technical solution of this utility model, the first strip 11 and the second strip 13 intersect to form through holes 181. The arrangement density of the through holes 181 can be adjusted to meet different light transmittance requirements. It is worth noting that by adjusting the length and intersection angle of the first strip 11 and the second strip 13, the first virtual boundary 161 can form an arc edge or a beveled edge to construct an arc-shaped screen or a beveled screen, or to adapt to the edge requirements of irregularly shaped screens such as circles and spheres. Therefore, since the first virtual boundary 61 is formed as a whole through a grid structure, it avoids the need for customization of each carrier plate, similar to LED grid screens, thereby improving production efficiency.

[0032] Reference Figure 12 or Figure 13 In one embodiment of this utility model, the first virtual boundary 161 is an arc edge or a slanted edge.

[0033] In this embodiment, if the first virtual boundary 161 is an arc edge, the multiple ends 12 are adjusted to be arranged along the arc trajectory, such as the outer arc edge of the circular screen 100, so that the edge of a single carrier assembly 1 adapts to the curved surface, and a complete arc is formed after splicing. If the first virtual boundary 161 is a slanted edge, by precisely controlling the length of the ends 12 of the first strip 11 / second strip 13, the line connecting the continuous ends 12 is made to be straight and slanted, such as the side of the polygonal screen 800, and the slanted edges of adjacent modules can be directly aligned and spliced.

[0034] Reference Figure 12 or Figure 13 In one embodiment of the present invention, the lengths of at least two first strips 11 increase sequentially along a first direction, and the lengths of at least two second strips 13 decrease sequentially along a second direction. The ends 12 of the at least two first strips 11 with sequentially increasing lengths, together with the ends 12 of the at least two second strips 13 with sequentially decreasing lengths, define the first virtual boundary 161.

[0035] In this embodiment, the strip ends 12 with increasing length and the strip ends 12 with decreasing length together define the first virtual boundary 161, forming a non-linear edge, which accurately matches the edge requirements of irregular screens and reduces deformation during splicing.

[0036] Reference Figure 12 or Figure 13 In one embodiment of the present invention, one side of the mesh structure is further defined by a plurality of continuous ends 12 to form a second virtual boundary 163, the second virtual boundary 163 being perpendicular to the second direction. And / or, one side of the mesh structure is further defined by a plurality of continuous ends 12 to form a third virtual boundary 165, the third virtual boundary 165 being parallel to the second direction.

[0037] In this embodiment, a single tilted boundary may not meet the requirements for overall module fixing or multi-directional splicing. Therefore, a straight edge boundary, such as a second virtual boundary 163 or a third virtual boundary 165, is added. The straight edge boundary can be used to fix the module to the rack assembly 3, while the tilted first virtual boundary 161 is used for the construction or splicing of irregularly shaped screens, thereby realizing functional zoning on the edges. For example, Figure 12 Two equal first body 11s form the first body group 141, and two equal second body 13s form the second body group 143.

[0038] Reference Figures 8 to 11 In one embodiment of the present invention, the carrier plate assembly 1 is formed by splicing together a plurality of sub-carrier plates 15, each of the sub-carrier plates 15 including a first sub-strip 151 and a second sub-strip 153 arranged in a cross manner to splice together to form the first strip 11 and the second strip 13.

[0039] In this embodiment, the carrier board assembly 1 is decomposed into multiple sub-carrier boards 15. By splicing the sub-carrier boards 15, it is easy to manufacture a large carrier board assembly 1 to meet the display requirements of large irregular screens.

[0040] Reference Figure 9 or Figure 11 In one embodiment of the present invention, the first sub-strip 151 and / or the second sub-strip 153 are provided with splicing holes 1511. The carrier plate assembly 1 also includes a connector. The two ends of the connector are respectively provided with first connecting holes. The first connecting holes and the splicing holes 1511 of the two sub-carrier plates 15 are respectively connected by fasteners to connect the two sub-carrier plates 15.

[0041] In this embodiment, fasteners are used to fix the splicing hole 1511 to the first connecting hole, thereby achieving a mechanical connection between the subcarrier plates 15. This ensures that the subcarrier plates 15 remain stable after splicing and reduces loosening caused by vibration or external force. At the same time, the detachable connectors allow for quick replacement of damaged subcarrier plates 15, reducing maintenance costs.

[0042] Optionally, each sub-carrier board 15 may have a half-hole 157 on one side. When two sub-carrier boards 15 are spliced ​​together, the two half-holes 157 are combined to form a complete through hole 181. The connector is also provided with a clearance hole, which partially or completely overlaps with the through hole 181, thereby minimizing the obstruction of the through hole 181 by the connector and improving the transparency of the LED module 10.

[0043] Reference Figure 7 In one embodiment of the present invention, the carrier plate assembly 1 is divided into an installation area 17 and a display area 18. A power supply interface 171 is provided on one side of the installation area 17. The display area 18 includes a first strip 11 and a second strip 13, with the second strip 13 formed on one side of the installation area 17.

[0044] In this embodiment, the carrier board assembly 1 is divided into an installation area 17 with a power supply interface 171 and a display area 18 with a grid structure. One side of the display area 18 can be cut to form a first virtual boundary 161, thereby avoiding cutting interference to the installation area 17 and ensuring that the installation area 17 can supply power to the display area 18 normally.

[0045] Reference Figure 11 In one embodiment of this utility model, the first strip 11 and / or the second strip 13 are provided with a second connecting hole 1513 through the thickness direction. And / or, a reinforcing part 155 is provided circumferentially at the connection between the first strip 11 and the second strip 13.

[0046] In this embodiment, the second strip 13 or the first strip 11 is provided with a second connecting hole 1513 along the thickness direction, which is used to fix the carrier plate assembly 1 to the frame assembly 3 with screws, thereby ensuring the structural stability of the LED module 10.

[0047] In addition, a reinforcing part 155 is provided along the circumferential direction at the intersection of the first strip 11 and the second strip 13, such as an outwardly protruding circular or square structure, thereby enhancing the node strength, preventing the deformation of the grid structure due to the weight of the LED beads 51 or external force, and ensuring the flatness of the LED bead 51 array, thereby improving the display quality.

[0048] Reference Figure 5 and Figure 6 The present invention also proposes an LED module 10, which includes a frame assembly 3, a plurality of LED beads 51 and a carrier assembly 1 as described above. The frame assembly 3 extends along the periphery of the carrier assembly 1 for mounting the carrier assembly 1. The plurality of LED beads 51 are arrayed on the side of the carrier assembly 1 away from the frame assembly 3 and located in the solid area between each of the through holes 181.

[0049] The specific structure of the carrier assembly 1 is as described in the above embodiments. Since the LED module 10 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0050] The control of LED 51 can be carried out in a single-point single-pass manner, with one driver chip controlling one LED 51, so that even after one side of the carrier board assembly 1 is cut into any shape, the LED 51 can still be lit.

[0051] In this embodiment, multiple LED beads 51 are arranged in an array on the carrier assembly 1. Compared with the liquid crystal display screen, the LED beads 51 can provide higher brightness, thereby improving the user's viewing experience. In addition, the rack assembly 3 is adapted to the shape of the carrier assembly 1, so that the LED module 10 can be formed into a curved screen or other irregular screen shape.

[0052] Reference Figures 14 to 17 In one embodiment of the present invention, the first virtual boundary 161 is an arc edge, the frame assembly 3 includes a first side beam 31, a second side beam 33 and an arc beam 35 connected end to end to form a fan-shaped frame, and the carrier plate assembly 1 is installed on one side of the fan-shaped frame.

[0053] One side of the first side beam 31 may also have a protruding rib 312, which encloses a storage groove 313 for installing a power supply. The power supply is connected to the interface 171 of the carrier plate assembly 1 through the connector 55 of the adapter and is led out through two power lines 53. In addition, a rotating cover 37 is provided, which is rotatably connected to the side wall of the storage groove 313 via a rotating shaft.

[0054] In this embodiment, the first virtual boundary 161 is set as an arc edge, so the overall edge of the carrier assembly 1 is fan-shaped. By adapting the shape of the rack assembly 3 to a fan-shaped frame and installing the carrier assembly 1 on one side of the fan-shaped frame, a fan-shaped screen is formed, which can be used as an irregularly shaped screen on its own.

[0055] Optionally, in the specific connection method of the first side beam 31, the second side beam 33, and the arc-shaped beam 35, the first mounting hole 381 and the second mounting hole 382 on one side of the first side beam 31 are respectively fastened to the tenth mounting hole 3810 and the eleventh mounting hole 3811 of the arc-shaped beam 35. The fourth mounting hole 384 and the fifth mounting hole 385 on the other side of the first side beam 31 are respectively fastened to the sixth mounting hole 386 and the seventh mounting hole 387 of the second side beam 33, wherein the fourth mounting hole 384 is formed on the connecting rib 314 of the first side beam 31. In addition, a third mounting hole 383 and a second mating hole 315 are also provided on one side of the first side beam 31. The third mounting hole 383 is used to fasten to another first side beam 31. The second mating hole 315 is used together with the first mating hole 611 of the first mating member 61 to pass through fasteners, so as to further fasten the two adjacent first side beams 31 through the first mating member 61. The first side beam 31 is also provided with a clearance opening 311 for the interface 171 of the carrier plate assembly 1 to pass through.

[0056] The ninth mounting hole 389 of the second side beam 33 is fastened to the twelfth mounting hole 3812 of the arc beam 35. The arc beam 35 includes a first mounting plate 351 and a second mounting plate 353 that are bent and connected. A connecting flange 3513 is also provided on one side of the first mounting plate 351, and the connecting flange 3513 has the twelfth mounting hole 3812. The first mounting plate 351 also has a thirteenth mounting hole 3813, which is connected to the second connecting hole 1513 of the carrier plate assembly 1 by fasteners. In addition, the second side beam 33 also has an eighth mounting hole 388, which is connected to the adjacent second side beam 33 by fasteners to fix the two adjacent second side beams 33.

[0057] Reference Figures 2 to 6 The present invention also proposes a circular screen 100, which includes a plurality of LED modules 10 as described above, wherein each of the LED modules 10 is a fan-shaped screen and the radial edges of two adjacent fan-shaped screens are spliced ​​together.

[0058] The specific structure of the LED module 10 is as described in the above embodiments. Since the circular screen 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0059] In this embodiment, multiple fan-shaped screens are spliced ​​together to form a circular screen 100, which facilitates the display of a large circular screen 100. Simultaneously, the design of the circular screen 100 can meet the splicing requirements of other irregularly shaped screens and satisfy the user's viewing experience.

[0060] For example, refer to Figure 3 and Figure 5 Four fan-shaped screens at 90° right angles are used to splice together a circular screen of 100.

[0061] Reference Figures 1 to 20 This utility model also proposes a spherical screen 1000, which includes a circular screen 100 as described above and a plurality of polygonal screens 800. Each polygonal screen 800 has a beveled edge on both sides, and the beveled edges of two adjacent polygonal screens 800 are spliced ​​together to form a spherical outer arc surface. The periphery of the circular screen 100 is spliced ​​with the top edge of the plurality of polygonal screens 800 to form a dome.

[0062] The specific structure of the circular screen 100 is as described in the above embodiments. Since the spherical screen 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0063] Among them, the polygonal screen 800 can be a trapezoidal screen or a hexagonal screen, etc. The second mounting plate 353 of the arc beam 35 has multiple third docking holes 3531, which are fastened to the support frame of the spherical screen 1000 to fix the circular screen 100.

[0064] In this embodiment, traditional rectangular modules struggle to fit spherical surfaces, resulting in uneven surfaces after splicing. This solution employs a partitioned splicing strategy. Each polygonal screen 800 has two sides designed with bevels at specific angles, such as 15° to 45° to the vertical. By adjusting the bevel angles, adjacent polygonal screens 800 align their bevels to form a spherical curvature. The perimeter of the circular screen 100 is spliced ​​with the top edges of multiple polygonal screens 800, forming the dome of the spherical screen 1000. By combining the circular screen 100 and the polygonal screens 800, a 360° × 180° spherical panoramic display is achieved, allowing viewers to enjoy a seamless view from any angle.

[0065] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
