[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] In the application, the term "some embodiments" is used to mean "used as an example, illustration or description". Any embodiment described as exemplary in this application is not necessarily to be construed as being more preferred or advantageous than other embodiments. The following description is given to enable any technician in the field to implement and use the present application. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other examples, known structures and processes will not be elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles disclosed in the present application.

[0033] In addition, the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the feature. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0034] It should be noted that the “board” mentioned in this application generally refers to a PCB board, but is not limited to this.

[0035] In the related art, during the process of splicing multiple LED light boards 20 to form an LED display screen, the power board 10 in the LED display screen needs to be electrically connected to the multiple LED light boards 20, which requires the layout of a connector electrically connected to the power board 10 at the center position of each LED light board 20. However, after the connector is arranged at the center position of the LED light board 20, the distance between the connectors of two adjacent LED light boards 20 in the LED display screen is large, and the size of the power boards 10 corresponding to the two LED light boards 20 will inevitably be larger, resulting in more materials required to produce the LED display screen, which in turn leads to a higher production cost of the LED display screen.

[0036] In order to solve the technical problem of high production cost of the above-mentioned LED display screen, the present application provides a LED display screen.

[0037] like Figure 1 to Figure 7 As shown, an LED display screen comprises:

[0038] The power board 10 is provided with a first connector 1001 and a second connector 1002;

[0039] At least two LED light boards 20, each of which is provided with a third connector 201;

[0040] Among them, the two LED light boards 20 are spliced ​​to form a group of LED light boards 20, at least one of the third connectors 201 in a group of LED light boards 20 is close to the splicing position, and the first connector 1001 and the second connector 1002 are both electrically connected to one third connector 201.

[0041] Specifically, the LED light board 20 may be a Mini LED light board 20, and the LED display screen is formed by splicing a plurality of LED light boards 20, and the power board 10 may provide power for each LED light board 20 in the LED display screen, and the power board 10 and the LED light board 20 are electrically connected by a plug-in connector. Among them, the power board 10 may be provided with at least one first plug-in connector 1001 and at least one second plug-in connector 1002, and a third plug-in connector 201 may be provided on each LED light board 20 in the LED display screen, and the first plug-in connector 1001 and the second plug-in connector 1002 are each electrically connected to a third plug-in connector 201, so that the power board 10 can provide power for a plurality of LED light boards 20 at the same time.

[0042] Among them, since multiple LED light boards 20 share one power board 10, and each LED light board 20 is electrically connected to the power board 10 using a connector, the position of the third connector 201 on two adjacent LED light boards 20 in the LED display screen plays a decisive role in the size of the power board 10.

[0043] Taking the splicing of two LED light boards 20 along the X direction as an example, if the third connectors 201 on the two LED light boards 20 are both located at the center position of their respective LED light boards 20, the spacing between the third connectors 201 on the two LED light boards 20 is equal to the spacing between the two adjacent first connectors 1001 and the second connector 1002 on the power board 10, so that the width of the power board 10 is at least not less than half of the sum of the widths of the two LED light boards 20; if the third connector 201 on one of the two LED light boards 20 is located at the leftmost side of the LED light board 20, and the third connector 201 on the other LED light board 20 is located at the rightmost side of the LED light board 20, then at this time the width of the power board 10 needs to be at least not less than the sum of the widths of the two LED light boards 20. It can be seen from this that the position of the third connector 201 on the two LED light boards 20 that need to be spliced ​​determines the width of the power board 10. The smaller the distance between the third connectors 201 on the two LED light boards 20 that need to be spliced, the smaller the width of the power board 10. At this time, the material cost of the LED display can be reduced by reducing the size of the power board 10, thereby reducing the production cost of the LED display.

[0044] In this embodiment, in order to reduce the production cost of the LED display screen, the present application reduces the distance between the third connectors 201 on the two LED light boards 20 that need to be spliced, that is, the third connector 201 on one or both of the LED light boards 20 is arranged close to the splicing position, thereby reducing the distance between the third connectors 201 on the two LED light boards 20, and then the size of the power board 10 can be reduced, thereby reducing the material cost of the LED display screen, so as to achieve the purpose of reducing the production cost of the LED display screen.

[0045] It should be noted that the models of the first connector 1001 and the second connector 1002 can be the same or different, as long as the first connector 1001 and the second connector 1002 can be plugged with the third connector 201 on the LED light board 20 to provide power to the LED light board 20. In other words, the models of the first connector 1001, the second connector 1002 and the third connector 201 can be selected according to actual applications, and this application does not make specific limitations.

[0046] It should also be noted that the structures of the two LED light panels 20 to be spliced ​​can be completely identical, and during the splicing process, it is only necessary to horizontally rotate one of the LED light panels 20 180 degrees for splicing.

[0047] Furthermore, in some embodiments, the two third connectors 201 in a group of LED light panels 20 are both close to the splicing position.

[0048] In this embodiment, by placing two third connectors 201 in a group of LED light panels 20 close to the splicing position, the distance between the corresponding first connector 1001 and the second connector 1002 on the power board 10 can be made smaller, and the width of the power board 10 can be further reduced to reduce the material cost of the power board 10, thereby achieving the purpose of producing LED display screens at a lower cost.

[0049] It should be noted that when the third connector 201 is designed close to the splicing position, it can be infinitely close to the splicing position, or a distance can be reserved between the third connector 201 and the splicing position, as long as the third connector 201 does not affect the corresponding LED light board 20, or can be adapted to the size of the power board 10. In other words, when the third connector 201 is designed close to the splicing position, it can be selected according to the actual application, and this application does not make specific restrictions.

[0050] In some embodiments, Figure 1 , Figure 2 , Figure 5 and Figure 6As shown, the LED display screen further includes a first unit box 301 ; wherein the power board 10 and at least one group of LED light boards 20 are sequentially arranged in the first unit box 301 .

[0051] In this embodiment, the power board 10 can be first assembled in the first unit box 301, and then at least one group of LED light boards 20 can be respectively assembled in the first unit box 301, and then the LED display screen can be assembled. In the process of assembling the LED light board 20 in the first unit box 301, the third connector 201 on the LED light board 20 needs to be plugged into the first connector 1001 and the second connector 1002 on the power board 10, so that the power board 10 can supply power to the LED light board 20.

[0052] Furthermore, in some embodiments, Figure 1 and Figure 2 As shown, at least four groups of the LED light boards 20 are arranged in the first unit box 301 , and each of the four groups of the LED light boards 20 corresponds to one power board 10 .

[0053] In this embodiment, at least four groups of LED light boards 20 can be spliced ​​in the first unit box 301, and four groups of LED light boards 20 correspond to one power board 10, that is, eight LED light boards 20 correspond to one power board 10. The eight LED light boards 20 can be spliced ​​in the first unit box 301 in 2*4, that is, in two rows and four columns.

[0054] It can be understood that after multiple LED light boards 20 are spliced ​​to form an LED display screen, the LED light boards 20 are arranged in an array in the LED display screen. The number of LED light boards 20 can be determined by the size of the LED display screen. The present application is not limited to an LED display screen spliced ​​by eight LED light boards 20.

[0055] Furthermore, in some embodiments, Figure 5 and Figure 6 As shown, the LED display screen also includes a second unit box 302, and the power board 10 includes a first power board 101 and a second power board 102; wherein, the second unit box 302 is spliced ​​with the first unit box 301, and the second unit box 302 is sequentially provided with the second power board 102 and at least one group of the LED light boards 20, and the first power board 101 is arranged in the first unit box 301; the first power board 101 and the second power board 102 are integrally formed to form the power board 10, and the first power board 101 and the second power board 102 are both provided with the first connector 1001 and the second connector 1002.

[0056] In this embodiment, the sizes of the first unit box 301 and the second unit box 302 can be the same, and eight LED light panels 20 can be spliced ​​in the first unit box 301 and the second unit box 302. The first unit box 301 and the second unit box 302 can be spliced ​​and formed as one piece to obtain a large-sized unit box, which can be spliced ​​to obtain a large-sized LED display screen.

[0057] It can be understood that the LED display screen provided in the present application can be a small-sized Mini LED display screen or a large-sized Mini LED display screen, as long as the LED display screen is obtained by splicing multiple LED light boards 20 and the third connectors 201 on the two spliced ​​LED light boards 20 are close to the splicing position.

[0058] In addition, in order to reduce the number of splicing times of the LED display screen and reduce the phenomenon of poor display caused by splicing, the first power board 101 located in the first unit box 301 and the second power board 102 located in the second unit box 302 can be formed as one piece, that is, one power board 10 can be divided into two areas, and the two areas are respectively provided with a first connector 1001 and a second connector 1002.

[0059] Furthermore, in some embodiments, Figure 6 and Figure 7 As shown, the second power board 102 has a rake structure.

[0060] In this embodiment, after the first power board 101 and the second power board 102 are integrally formed, a rake structure can be provided on the second power board 102, which can not only reduce the material cost of the power board 10, but also can be designed in batches when the power board 10 is produced. Figure 8 The structure shown in the figure can be produced, thereby further reducing the material cost of the power board 10.

[0061] Furthermore, in some embodiments, Figure 7 As shown, the first connector 1001 and the second connector 1002 provided on the second power board 102 are both located at the rake tooth end of the second power board 102 .

[0062] Furthermore, in some embodiments, Figure 3 As shown, at least one of the LED light boards 20 is further provided with a fourth connector 202 symmetrical to the third connector 201 .

[0063] In this embodiment, the fourth connector 202 can be used as a spare connector, which can avoid replacing the LED light board 20 when the third connector 201 on the LED light board 20 is damaged. At this time, the LED light board 20 only needs to be rotated horizontally 180 degrees, and the fourth connector 202 can be connected to the first connector 1001 or the second connector 1002 on the power board 10, so that the LED light board 20 can be used normally again.

[0064] It can be understood that the present application can set the fourth connector 202 on all LED light boards 20 in the LED display screen, and can also set the fourth connector 202 on some LED light boards 20. It can be selected according to the actual application, and this application does not make any specific limitation.

[0065] Furthermore, if Figure 2 and Figure 6 As shown, in the LED display screen, a protective cover plate 40 is further provided between the LED light board 20 and the power board 10. Specifically, by providing the protective cover plate 40 on the power board 10, electric shock accidents can be avoided during the process of loading and unloading the LED display screen. The material of the protective cover plate 40 can be Mylar sheet, and it can be fixed on the power board 10 by snapping.

[0066] The LED display screen provided in the present application includes at least two LED light boards 20 and a power board 10, the power board 10 is provided with a first connector 1001 and a second connector 1002, each LED light board 20 is provided with a third connector 201, the first connector 1001 and the second connector 1002 are electrically connected to a third connector 201, two LED light boards 20 are spliced ​​to form a group of LED light boards 20, at least one third connector 201 in a group of LED light boards 20 is close to the splicing position, so that the distance between the first connector 1001 and the second connector 1002 can be shortened, the size of the power board 10 can be reduced, and the material cost of the power board 10 can be reduced, thereby achieving the purpose of reducing the production cost of the LED display screen.

[0067] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed in the present application, and these modifications or replacements should be included in the protection scope of the present application.
