[0018] To better understand the technical content of this utility model, the technical solution of this utility model will be further introduced and explained below with reference to the schematic diagram, but it is not limited thereto.

[0019] Reference Figure 1 , Figure 1 This is a schematic structural block diagram of a specific embodiment of the LED display screen 100 of this utility model. In the embodiment shown in the figure, the LED display screen 100 includes a display module 10 and an LED control module 20. The display module 10 includes a first radio frequency module 11, a first FPGA module 12, and a display glass screen 13. The first FPGA module 12 is connected to the first radio frequency module 11 and the display glass screen 13, and is used to drive the display glass screen 13 to work according to the instructions from the first radio frequency module 11. The LED control module 20 includes a second radio frequency module 21 and a second FPGA module 22. The second FPGA module 22 is connected to the second radio frequency module 21 and an external host computer, and is used to control the operation of the display module 10 according to the instructions from the external host computer. Based on the above design, the display module 10 and LED control module 20 in the LED display screen 100 of this utility model realize data transmission wirelessly, which can realize high-speed data transmission with flexibility and no spatial limitations. It does not require signal connectors, which can avoid the problems of low data transmission quality and potential water leakage caused by signal connectors loosening after long-term use in traditional LED display screens 100.

[0020] In some embodiments, the second FPGA module 22 includes a network port module 221, a control parsing module 222, and a second encoding module 223. The network port module 221 is connected to the network port of an external host computer. The control parsing module 222 is connected to the network port module 221 and is used to parse the instructions from the network port module 221 to generate corresponding control instructions. The second encoding module 223 is connected to the control parsing module 222 and the second radio frequency module 21 and is used to encode the control instructions from the control parsing module 222 and send them to the display module 10 through the second radio frequency module 21. Preferably, the control parsing module 222 can be implemented based on a processor. Based on the above design, the second radio frequency module 21 sends the encoded control instructions to the display module 10, and the first radio frequency module 11 in the display module 10 receives the encoded control instructions.

[0021] In some embodiments, the first FPGA module 12 includes a first decoding module 121, which is connected to the first radio frequency module 11 and the display glass screen 13. The first decoding module 121 decodes control commands received through the first radio frequency module 11 to drive the display glass screen 13 to operate. Understandably, the display glass screen 13 includes an LED array. In this invention, after the first radio frequency module 11 receives the encoded control command from the second radio frequency module 21, the first decoding module 121 decodes the encoded control command to control the LED array in the display glass screen 13 to operate according to the decoded control command, so that each LED in the LED array can emit corresponding red, blue, green, etc., thereby enabling the entire display glass screen 13 to display the image normally.

[0022] Furthermore, the first FPGA module 12 also includes a first encoding module 122, which is connected to the display glass screen 13 and the first radio frequency module 11. The first encoding module 122 encodes the status feedback information from the display glass screen 13 and sends the encoded information to the second radio frequency module 21 via the first radio frequency module 11. The second FPGA module 22 also includes a second decoding module 224, which is connected to the second radio frequency module 21 and the network port module 221. Based on the above design, after the control command decoded by the first decoding module 121 drives the display glass screen 13 to work, the display glass screen 13 can also feed back its own status to an external host computer. Specifically, the first encoding module 122 encodes the status feedback information of the display glass screen 13 and sends it to the second decoding module 224 via the first radio frequency module 11 and the second radio frequency module 21. After decoding by the second decoding module 224, the information is fed back to the external host computer via the network port module 221, allowing the external host computer to know the status of the LED display screen 100 in real time.

[0023] To achieve DC equalization and improve data transmission accuracy, in this embodiment, both the first encoding module 122 and the second encoding module 223 include an 8b / 10b encoder, and both the second decoding module 224 and the first decoding module 121 include an 8b / 10b decoder. Preferably, both the first RF module 11 and the second RF module 21 can be selected from a millimeter-wave transceiver of model ST60A2G0, which supports half-duplex communication and has a data rate of 1 Mbit / s to 5 Gbit / s. When the LED display screen 100 of this utility model is working, assuming that the control command input from the 8b / 10b encoder is represented by HGFEDCBA from high to low, the 8B / 10B encoder divides the 8-bit data into two subgroups: the high 3 bits HGF and the low 5 bits EDCBA. The low 5 bits EDCBA are encoded by 5B / 6B and mapped to abcdei, while the high 3 bits are encoded by 3B / 4B and mapped to fghj. Finally, they are combined into abcdeifghj and sent to ST60A2G0, and then transmitted in the form of millimeter waves to achieve wireless transmission.

[0024] Reference Figure 2 , Figure 2 This is a schematic structural block diagram of a specific embodiment of the LED display system of this utility model. (In conjunction with...) Figure 1 In the embodiment shown in the accompanying drawings, the LED display system includes a host computer 200 and multiple LED displays 100 as described in the above embodiments. The second FPGA module 22 of the LED control module 20 in each LED display 100 is connected to the network port 201 of the host computer 200. In this embodiment, the network port 201 of the host computer 200 uses the UDP protocol for sending control commands and receiving feedback. Correspondingly, the network port module 221 of the second FPGA module 22 in the LED display 100 also uses the UDP protocol for communication with the host computer 200.

[0025] In summary, the LED display screen and LED display system of this utility model adopt wireless data transmission, which can realize flexible and high-speed data transmission without spatial limitations. In addition, the use of half-duplex communication mode can also realize the status feedback of the LED display screen.
