[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit the exemplary embodiments according to the present application. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprise" and / or "include" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0028] In the existing technology, the flexible LED display can be made by using FPC for PCB materials, or by making the PCB thinner, such as 0.3, 0.5, 0.8, 1mm, etc. This will result in a smaller rotation angle between adjacent PCBs. The cost of FPC materials for PCB is expensive, and it is almost impossible to produce more than four layers of boards with current technology. If the thickness of the PCB is reduced, there will always be a relatively large minimum diameter because if it is too small, the PCB will break, and the components resistors and capacitors will also have the risk of breaking.

[0029] like Figure 1 and Figure 2 As shown, in this embodiment, the LED display module includes: a plurality of LED light boards 10 and a plurality of flexible connectors 20. The plurality of flexible connectors 20 are arranged on the rear side of the plurality of LED light boards 10, each flexible connector 20 connects two adjacent LED light boards 10, a first side of each flexible connector 20 is connected to one of the two adjacent LED light boards 10, and a second side of each flexible connector 20 is connected to the other of the two adjacent LED light boards 10.

[0030] By applying the technical solution of the utility model, a plurality of flexible connectors 20 are arranged on the rear side of a plurality of LED light boards 10, two adjacent LED light boards 10 are connected by the flexible connectors 20, and the two sides of each flexible connector 20 are respectively connected to two adjacent LED light boards 10. Through the above arrangement, each flexible connector 20 can connect two adjacent LED light boards 10, and then a plurality of flexible connectors 20 can connect a plurality of LED light boards 10, and the flexible connector 20 also enables two adjacent LED light boards 10 to swing relative to each other, that is, the angle between the two adjacent LED light boards 10 can be changed, and then the plurality of LED light boards 10 can be bent into different shapes. The flexible connector 20 makes the connection structure between the two adjacent LED light boards 10 simple, and also makes the connection between the two adjacent LED light boards 10 more stable, that is, the two adjacent LED light boards 10 will not slide relative to each other after being connected, and then the plurality of LED light boards 10 will not slide relative to each other after being connected, which ensures the use of the LED display module and also ensures that the display effect of the LED display module will not be affected. Therefore, the technical solution of the present application effectively solves the problem in the related art that adjacent light panels slide after being connected, thus affecting the display effect of the LED display screen.

[0031] It should be noted that in this embodiment, the number of LED light boards 10 is 8. Of course, in other embodiments, the number of LED light boards 10 may also be 3, 4, 6 or more. There is a gap between adjacent LED light boards 10, so that when the angle between two LED light boards 10 connected to a flexible connector changes, the LED light board 10 will not interfere with the movement of another adjacent LED light board 10.

[0032] like Figure 2 , Figure 4 as well as Figure 7 As shown, in this embodiment, the flexible connector 20 is a flexible film 21. The flexible film 21 enables the adjacent LED light panels 10 to swing at multiple angles, thereby enabling multiple LED light panels 10 to form different shapes after being connected, so that the LED display module can better adapt to usage requirements.

[0033] like Figure 2 , Figure 4 as well as Figure 7 As shown, in this embodiment, the thickness of the flexible film 21 is between 0.1 mm and 1 mm. The above configuration makes the thickness of the flexible film 21 small, so that the flexible film 21 will not interfere with the swing of the adjacent LED light board 10. The flexible film 21 can not only connect the adjacent LED light boards 10, but also will not break under normal use, thereby avoiding affecting the display effect of the LED display module.

[0034] It should be noted that in this embodiment, the thickness of the flexible film 21 is 0.2 mm, which has good toughness. Of course, it can also be 0.15 mm, 0.3 mm, 0.5 mm, 0.9 mm, or other values.

[0035] like Figure 3 and Figure 4 As shown, in this embodiment, the LED display module also includes an adhesive layer arranged between the flexible connector 20 and the LED light board 10. The overall structural strength after the adhesive layer is connected to the flexible connector 20 is better, and then the adjacent LED light boards can have better connection stability under the connection effect of the adhesive layer and the flexible connector 20.

[0036] Preferably, in this embodiment, the adhesive layer may use a backing glue having the advantages of high temperature resistance and good strength.

[0037] like Figure 5 and Figure 6 As shown, in this embodiment, the LED display module further includes a fastener, and the flexible connector 20 is connected to the LED light board 10 through the fastener. The fastener makes the connection between the flexible connector and the LED light board 10 more stable, and thus the connection between two adjacent LED light boards 10 connected to one flexible connector 20 is more stable, that is, when the LED display module is in use, the flexible connector 20 will not be separated from the LED light board 10.

[0038] like Figure 1 and Figure 7As shown, in this embodiment, a mounting hole 11 is provided on the LED light board 10, a first connecting hole 22 is provided on the flexible connector 20, a second connecting hole is provided on the adhesive layer, and the fastener passes through the first connecting hole 22 and the second connecting hole and is connected in the mounting hole 11. The above arrangement enables the fastener to pass through the first connecting hole 22 and the second connecting hole to be connected to the mounting hole 11, that is, the fastener can pass through the flexible connector 20 and the adhesive layer to be connected to the LED light board 10, that is, the fastener connects the flexible connector 20, the adhesive layer and the LED light board 10, so that the adjacent LED light boards 10 are more stably connected under the action of the flexible connector 20, the adhesive layer and the fastener when in use, thereby ensuring the display effect of the LED display module.

[0039] like Figures 4 to 7 As shown, in this embodiment, the fastener is a screw. The screw can not only connect the flexible connector 20, the adhesive layer and the LED light board 10, but also enable the flexible connector 20 and the adhesive layer to be fixed to the LED light board 10, and also make the connection between the flexible connector 20, the adhesive layer and the LED light board 10 easier.

[0040] Specifically, in this embodiment, the screws are M1 screws.

[0041] Preferably, in this embodiment, there are multiple screws, some of which are connected to one of two adjacent LED light boards 10, and the other part of the screws are connected to the other of the two adjacent LED light boards 10. The two parts of the screws on the two adjacent LED light boards 10 are symmetrically arranged, and the multiple screws on each LED light board 10 are arranged at equal intervals. This makes the force on the flexible connector 20 and the adhesive layer more reasonable, and also makes the force on the LED light board 10 more reasonable, avoiding damage to the flexible connector 20 and the LED light board 10 during use.

[0042] Of course, in the embodiment not shown in the figure, the fastener can also be a connecting column, which passes through the first connecting hole 22, the second connecting hole and is connected to the mounting hole 11, and the surface of the connecting column in contact with the flexible membrane 21 is provided with a convex edge, so that the contact between the connecting column and the flexible membrane 21 is more stable. The matching relationship between the connecting column and the diameter of the first connecting hole 22, the second connecting hole, and the mounting hole 11 is an interference fit, which ensures the connection stability of the fastener with the flexible connector 20 and the LED light board 10.

[0043] like Figure 1 and Figure 2As shown, in this embodiment, the material of the flexible film 21 is rubber. The material of the flexible film 21 is rubber, which makes the processing of the flexible film 21 easier and the manufacturing cost lower. It also ensures that after the flexible film 21 is connected to the LED light board 10, the flexible film 21 will not cause the adjacent LED light board 10 to short-circuit, that is, it avoids the damage caused by the short circuit between the adjacent LED light boards 10 when the LED display module is in use, and ensures the normal use of the LED display module.

[0044] Preferably, in this embodiment, the flexible membrane is made of a flexible ultra-thin rubber material with good toughness.

[0045] like Figure 1 , Figure 2 as well as Figures 4 to 7 As shown, in this embodiment, each LED light board 10 is a strip structure, and the flexible connector 20 is extended along the length direction of the LED light board 10. The above arrangement enables the flexible connector 20 to cover more areas of the LED light board 10, that is, the connection between the flexible connector 20 and the LED light board 10 is more stable.

[0046] Specifically, in this embodiment, the ratio of the length of the flexible connector 20 to the length of the LED light board 10 is at least 2:3. This arrangement enables the flexible connector 20 to cover more areas in the length direction of the LED light board 10, so that adjacent LED light boards 10 will not twist under the connection of the flexible connector 20, thereby avoiding the breakage of the flexible connector 20 due to the twisting of the LED light board 10, which affects the display effect of the LED display module.

[0047] Preferably, in this embodiment, the length of the flexible connector 20 is the same as the length of the LED light board 10, so that the connection between adjacent LED light boards 10 is more stable. The ratio of the width of the area where the flexible connector 20 contacts the LED light board 10 to the length of the LED light board 10 is at least 0.08, and the ratio of the width of the area where the adhesive layer contacts the LED light board 10 to the length of the LED light board 10 is at least 0.08, so that the connection area between the flexible connector 20, the adhesive layer and the LED light board 10 is larger, thereby making the connection between the flexible connector 20, the adhesive layer and the LED light board 10 more stable.

[0048] Of course, in an embodiment not shown in the figure, the flexible connector 20 may also include a plurality of flexible connectors of the same length, and the plurality of flexible connectors are connected to the LED light board 10 at intervals along the length direction of the LED light board 10. In this way, when adjacent LED light boards 10 are connected, not only the connection stability of adjacent LED light boards 10 can be ensured, but also the use of the flexible film 21 can be reduced, thereby reducing manufacturing costs.

[0049] like Figures 1 to 7As shown, in this embodiment, the LED display device includes: a box body and an LED display module arranged on the front side of the box body, and the LED display module is the above-mentioned LED display module. The above-mentioned LED display module is connected by a flexible connector 20, so that adjacent LED light boards 10 can swing relative to each other, and then after multiple LED light boards 10 are connected, the angle between adjacent LED light boards 10 is changed, and the LED display module can form a variety of different shapes, and also after adjacent LED light boards 10 are connected, relative sliding will not occur, avoiding the LED light board 10 sliding and affecting the effect of the LED display module. The LED display device with the above-mentioned LED display module also has the above-mentioned advantages.

[0050] Specifically, a socket is provided on the rear side of the LED light board 10 to facilitate the connection between the LED light board 10 and the box.

[0051] In this embodiment, the flexible film is directly connected to the LED light board, eliminating other structural components, effectively improving stability and reliability, and at the same time being easy to manufacture and low in cost. The PCB of the LED light board is a conventional material, does not need to be made into an FPC, and the number of layers is not limited. The flexible connector can be implemented by fixing the shaft with hardware or by hinges, but the rotation angle achieved will be relatively small, the cost is relatively high, and the structure is relatively complex. The flexible connector 20 is simple in design, highly reliable, and low in cost.

[0052] After the multiple LED light panels in the LED display module swing relative to each other, a curved display screen with any customized angle can be realized. Figure 1 As shown in FIG. 1 , an LED display module can be made with LED lamp beads protruding outward on the LED lamp board. Figure 4 As shown, an S-shaped LED display module can be made. Figure 6 As shown, an LED display module can be made with the LED lamp beads on the LED lamp board recessed.
