[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0036] Please refer to Figure 1 , 2 , Figure 1 This is a three-dimensional structural diagram of a display screen frame provided in an embodiment of the present invention. Figure 2 This is a partial three-dimensional structural diagram of an LED display screen provided in an embodiment of the present invention; the display screen frame includes a flexible substrate 10 and a plurality of flexible support blocks 20.

[0037] Please combine Figure 3-5 The flexible substrate 10 has a first surface 110 and a second surface 120 facing away from each other, and the plurality of flexible support blocks 20 are connected at intervals on the first surface 110.

[0038] The second surface 120 has a mounting groove 1201 with openings at both ends along the length of the flexible substrate 10, and the mounting groove 1201 is used to mount the display module 30.

[0039] Specifically, the flexible substrate 10 and the plurality of flexible support blocks 20 can be an integral structure or a structure connected by bonding or other means. The flexible substrate 10 is generally a square structure, with the first surface 110 and the second surface 120 being two opposing surfaces. The plurality of flexible support blocks 20 are spaced apart on the first surface 110. The shapes of the flexible support blocks 20 can be the same or different. The specific shape of the flexible support blocks 20 can be set according to the shape and size of the flexible substrate 10, or according to the size of other components to be installed on the first surface 110. A mounting groove 1201 is formed on the second surface 120, recessed towards the first surface 110. The mounting groove 1201 has openings at both ends along the length of the flexible substrate 10. The size of the display module 30 matches the shape and size of the bottom of the mounting groove 1201. The display module 30 can be installed into the mounting groove 1201 from both ends of the mounting groove 1201, thereby forming a... Figure 2 The LED display screen shown.

[0040] Here, the LED display screen includes the display frame and multiple display modules 30. Each display module 30 includes a PCB board 310 and multiple LED beads 320. The PCB board 310 is connected to the bottom of the mounting groove 1201, and the multiple LED beads 320 are arranged in an array on the side of the PCB board 310 facing away from the bottom of the groove.

[0041] Specifically, the PCB board 310 is connected to the bottom of the mounting groove 1201. The specific connection method includes, but is not limited to, bonding or screw connection. The multiple LED beads 320 are arranged in an array on the side of the PCB board 310 facing away from the bottom of the groove, thereby forming a display surface at the bottom of the mounting groove 1201.

[0042] When the LED display screen of this embodiment of the invention is applied to a ski resort, the side of the display screen frame facing away from the display module 30 is connected to the fence of the ski resort, and the display surface faces the direction of the competition. When athletes on the field collide with the LED display screen, they will come into contact with the display module 30. The display screen frame, composed of the flexible substrate 10 and the plurality of flexible support blocks 20, can absorb a certain amount of impact energy when the display module 30 is impacted, thereby effectively preventing athletes from being injured and ski equipment and display devices from being damaged. This can effectively improve the experience of using the LED display screen on the ski resort.

[0043] Here, the flexible substrate 10 has a certain degree of elasticity, enabling the display frame to have a certain energy absorption effect. Furthermore, the plurality of flexible support blocks 20 protruding from the rear of the flexible substrate 10, and the fact that these flexible support blocks 20 are not connected together but spaced apart, further enhances the energy absorption effect of the display frame. Additionally, the plurality of display modules 30 are installed within the mounting groove 1201, preventing displacement of the display modules 30 upon impact and ensuring good display performance.

[0044] Furthermore, in other preferred embodiments of the present invention, at least a portion of the flexible support block 20 is provided with a first Velcro 210 on the side facing away from the flexible substrate 10.

[0045] Specifically, the first Velcro 210 is provided on the soft support block 20 behind the display screen frame. The first Velcro 210 can be quickly installed and removed from the ski resort fence, thereby improving the deployment efficiency of the LED display screen.

[0046] Here, the first Velcro 210 is provided on a plurality of flexible support blocks 20 corresponding to the perimeter and middle position of the flexible substrate 10 to ensure the reliability of the connection between the display frame and the ski resort fence.

[0047] Furthermore, in other preferred embodiments of the present invention, a second Velcro 105 is provided at the top of the mounting groove 1201 and the top of the flexible substrate 10.

[0048] Specifically, the second Velcro 105 is disposed at the top of the mounting groove 1201, that is, the second Velcro 105 is disposed on the second surface 120 of the flexible substrate 10 on the upper and lower sides of the display module 30. Here, the second Velcro 105 is used to attach physical advertising boards, etc., on the ski resort. In addition, the second Velcro 105 is also disposed at the top of the flexible substrate 10, that is, at the bottom top of the display screen frame. Here, the second Velcro 105 is used to connect with the ski resort fence, further improving the reliability of the connection between the LED display screen and the ski resort fence.

[0049] Furthermore, in other preferred embodiments of the present invention, the flexible substrate 10 includes a first side 101 and a second side 102 located in the direction of the openings at both ends of the mounting groove 1201;

[0050] The first side 101 is provided with a plug post 1011, and the second side 102 is provided with a plug hole 1021 that can accommodate the plug post 1011.

[0051] Specifically, the first side 101 and the second side 102 are the left and right sides of the flexible substrate 10 along its length, respectively. A plurality of insertion posts 1011 are provided at intervals on the first side 101, and a plurality of insertion holes 1021 are provided at intervals on the second side 102. The size and position of the plurality of insertion posts 1011 and the plurality of insertion holes 1021 are corresponding. When two display screen frames are spliced ​​left and right, the plurality of insertion posts 1011 on one display screen frame can be inserted into the plurality of insertion holes 1021 on the other display screen frame, so that a relatively reliable plug-in connection can be formed between the two adjacent LED displays, thereby improving the reliability and work efficiency when connecting multiple LED displays.

[0052] Furthermore, in other preferred embodiments of the present invention, a first magnet 1012 is provided on the first side 101, and a second magnet 1022 or an iron block is provided on the second side 102 that can be connected to the first magnet 1012.

[0053] Specifically, multiple first magnets 1012 are spaced apart on the first side 101, while multiple second magnets 1022 or iron blocks are spaced apart on the second side 102. The arrangement can be embedded or flush with the end face using screws. The positions of the first magnets 1012 and the second magnets 1022 or iron blocks correspond, allowing the first magnets 1012 to magnetically connect with the second magnets 1022 or iron blocks. This magnetic connection method allows for initial positioning between adjacent LED displays and increases the strength of the connection between them.

[0054] Furthermore, in other preferred embodiments of the present invention, the display frame further includes a first end plate 103 and a second end plate 104, wherein the first end plate 103 is inserted into the first side 101 and the second end plate 104 is inserted into the second side 102.

[0056] It is conceivable that the first end plate 103 has a plurality of insertion holes 1021 spaced apart on the side facing the first side 101, and the second end plate 104 has a plurality of insertion posts 1011 spaced apart on the side facing the second side 102. As in the above embodiment, the first end plate 103 and the first side 101 are connected by insertion, while the second end plate 104 and the second side 102 are connected by insertion.

[0057] Furthermore, in other preferred embodiments of the present invention, the display frame further includes a safety plate 40 for connecting a safety rope, the safety plate 40 being disposed on the first surface 110 and located at the center of the plurality of soft support blocks 20.

[0058] Here, the safety plate 40 is disposed on the back of the display screen frame. Specifically, the safety plate 40 is fixed to the first surface 110 of the flexible substrate 10 by screws. The safety plate 40 is located at the center of the plurality of flexible support blocks 20, such as at the center of the flexible substrate 10 or slightly above the center. The safety plate 40 has through holes for the safety rope to pass through and connect. The safety rope is used to initially secure the display screen frame when it is connected to the ski resort fence.

[0059] Furthermore, in other preferred embodiments of the present invention, the flexible substrate 10 and the plurality of flexible support blocks 20 are both made of EVA cotton.

[0060] Here, the EVA cotton has good elasticity and toughness, as well as good processability, which can effectively improve the energy absorption performance of the display module 30 when the display frame is applied to the ski resort.

[0063] Two adjacent PCB boards 310 are connected by passing through the first through hole 510 on the same connecting piece 50 via the first connecting post 3301 on their respective connecting plates 330.

[0064] The second connecting post 3302 on each of the connecting plates 330 passes through the second through hole 520 on the corresponding connecting piece 50 and is connected to the flexible substrate 10.

[0065] Specifically, multiple connecting plates 330 are provided at intervals around the edge of each PCB board 310 on the side opposite to the LED bead 320. The connecting plates 330 are fixedly connected to the PCB board 310 by screws, and multiple first connecting posts 3301 and second connecting posts 3302 extending towards the bottom of the slot are provided on the connecting plates 330. Multiple connecting pieces 50 are provided on the connecting plate 330 and the bottom of the groove. The number of connecting pieces 50 is the same as that of the connecting plate 330, and their positions correspond to each other. The first through hole 510 and the second through hole 520 on each connecting piece 50 correspond to the first connecting post 3301 and the second connecting post 3302 of the connecting plate 330, respectively. When two PCB boards 310 are spliced, two adjacent PCB boards 310 are fixed by screws through the first connecting post 3301 on their respective connecting plates 3301 passing through the first through hole 510 on the same connecting piece 50, so that the two adjacent PCB boards 310 are interlocked and fixed by the connecting pieces 50 above them.
