On the other hand, wired connection requires wiring, and the wiring methods of LED boxes at different locations are different. For example, the wiring method at the corner is different from that at other locations. Therefore, the connection of LED boxes is relatively cumbersome. Utility Model Content

[0025] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0026] The above-mentioned LED cabinet and LED display screen of the present application can be applied to various scenarios where LED display screens need to be formed by splicing LED cabinets, and the following is an explanation through specific implementation methods:

[0027] In an optional embodiment, if Figure 1 As shown, an LED box, the LED box includes a processor, and the four sides of the LED box are respectively provided with wireless interfaces;

[0028] The wireless interface is connected to the processor.

[0029] Optionally, the processor may be a FPGA processor.

[0030] Among them, a variety of wireless methods can be used to achieve wireless transmission of the LED box. In an optional implementation, the wireless interface is a millimeter wave wireless interface;

[0031] In specific implementation, the LED display boxes are isolated and independent, and the adjacent LED boxes transmit signals through millimeter wave communication, such as Figure 1 As shown, a single LED box contains an FPGA chip, and a millimeter wave wireless transmission chip is distributed around the box. The LED boxes are connected by millimeter wave wireless connections instead of wired connections, and the millimeter wave wireless transmission chips are full-duplex communication;

[0032] Currently, millimeter wave communication can achieve a communication rate of up to 10Gbps, with a signal delay of less than 3ns, and signal jitter can be controlled at the ps level. In addition, by controlling the power, millimeter waves can easily achieve a communication distance of centimeters. Based on the above three points, it can fully meet the requirements of LED display cabinets for high-speed and stable signal transmission.

[0033] In another optional implementation, in order to realize the selection of the wireless interface arranged around the LED box, the selection can be realized by setting a selection switch in the FPGA processor;

[0034] When implementing it specifically, Figure 2-3 As shown, the processor includes a controller, a control bus and a selection switch;

[0035] The controller is connected to one end of the selection switch via a control bus;

[0036] The other end of the selection switch includes four interfaces, and the four interfaces are respectively connected to the wireless interfaces around the LED box in a one-to-one correspondence;

[0037] Also includes the drive;

[0038] The driver is connected to the controller via a data bus, that is, the driver drives the controller to turn on a switch on a wireless interface, thereby connecting the corresponding wireless interface, and data transmission is achieved through the wireless interface. The controller controls which communication link is turned on under the drive of the driving signal. This belongs to the prior art and will not be described in detail here.

[0039] like Figure 2 , 3 As shown, the selection switch has four interfaces, namely IO Ax, IO Bx, IO Cx and IO Dx, which are connected to the wireless interfaces set on the four sides of the LED box respectively. Figure 3 As shown, switches are respectively provided between interfaces IO Ax and IOBx, IO Ax and IO Cx, IO Ax and IO Dx, IO Bx and IOCx, IO Bx and IO Dx, and IO Cx and IO Dx. Under the driving signal of the driver, it can be selected to control which two interfaces' switches are closed. If the switches are closed, the links between the corresponding two interfaces are connected.

[0040] like Figure 4 The LED display screen formed by splicing multiple LED cabinets is shown in the figure. The corresponding communication signal transmission direction formed by splicing different LED cabinets is as follows Figure 5 As shown, combined Figure 4 , 5 The interfaces for connecting the LED boxes numbered 1, 2, 3, 6, 7, 10, 11, and 12 are the wireless interfaces on both sides of the horizontal direction. Figure 2 The layout shown in FIG. 1 is to connect the switch between the interfaces IOCx and IO Ax, and the LED boxes numbered 4, 5, 8, and 9 are connected to the wireless interfaces on the two adjacent sides. That is, if the Figure 2 In the layout shown, the LED box numbered 4 is connected to the switch between the interfaces IO Cx and IO Dx, the LED box numbered 5 is connected to the switch between the interfaces IO Cx and IO Bx, the LED box numbered 8 is connected to the switch between the interfaces IO Ax and IO Dx, and the LED box numbered 9 is connected to the switch between the interfaces IO Ax and IO Bx;

[0041] Since wireless interfaces are arranged on all sides of the LED boxes in this embodiment, and adjacent LED boxes are connected to each other by wireless communication, if the wireless interface on one side of the LED box fails and cannot transmit signals, it is not necessary to replace the LED box immediately, but another interface can be arranged to realize communication connection, such as Figure 6 As shown in FIG. 1 , when it is found that the wireless interface on the left side of the LED box numbered 5 fails, the wireless interface on the lower side of the LED box numbered 3 can be connected to the wireless interface on the upper side of the LED box numbered 6 to transmit signals, or the wireless interface on the lower side of the LED box numbered 6 can be connected to the wireless interface on the upper side of the LED box numbered 6 to transmit signals. Figure 7 As shown, signal transmission is achieved through the wireless interface on the lower side of the LED box numbered 5, that is, the signal transmission path is: 1->2->3->4->5->12->11->10->9->8->7->6.

[0042] In another optional embodiment, Figure 4 As shown, an LED display screen is formed by splicing a plurality of LED boxes as described in any of the above embodiments, and adjacent LED boxes communicate with each other wirelessly.

[0043] In summary, the utility model provides an LED box and LED display screen, in which wireless interfaces are respectively arranged around the LED box, so that adjacent LED boxes can be connected wirelessly, and wireless interfaces are arranged around the LED box. On the one hand, adjacent LED boxes are connected wirelessly, and various wireless transmission methods can be flexibly adopted to achieve high-speed signal transmission, low transmission delay and strong anti-interference, thereby improving signal transmission performance. On the other hand, each LED box has a unified specification, which is convenient for disassembly and assembly, and there is no need to disassemble and assemble LED boxes with specific wiring at specific locations. In addition, signal transmission of the wireless connection method is not affected by hardware. Since wireless interfaces are arranged around the LED box, even if a wireless interface fails, wireless interfaces in other directions can be adopted by selecting switches to achieve communication connection, further facilitating the disassembly and assembly of the LED box. Therefore, it is possible to facilitate the disassembly and assembly of the LED box while improving the transmission performance between the LED boxes.
