Detailed Implementation

[0050] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the invention. To better illustrate the following embodiments, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions; it is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0051] Example 1

[0052] like Figure 1 As shown, this embodiment provides an LED cloud screen device 52, which includes a cloud screen housing 100. The front of the cloud screen housing 100 is provided with an LED display screen, and the back is provided with a network cable interface and a video line interface.

[0053] The cloud screen enclosure 100 is enclosed by a cover plate located on the back. The cloud control board 1, LED controller 2 and power circuit board are provided on the inner side of the cover plate. In order to make the heat dissipation of the device more efficient, the LED controller 2 and the power circuit board are located on one side of the back of the cover plate of the cloud screen enclosure 100, and the cloud control board 1 is located on the other side.

[0054] An LED display module 31 is provided on the inner side of the LED display screen on the front of the cloud screen housing 100, which is used to control the display of the corresponding LED display screen.

[0055] The power circuit board is connected to the cloud control board 1 and the LED controller 2 respectively;

[0056] The cloud control board 1 is connected to the LED controller 2 and also connects to an external signal source via a network cable interface. The cloud control board 1 is used to receive the signal source signal and decode it into a video signal.

[0057] The LED controller 2 is connected to the LED display module 31. The LED controller 2 is connected to other LED cloud screen devices 52 through a video line interface, and is also connected to the control host 4 through a network cable to receive control signals. The LED controller 2 is used to receive the video signal from the cloud control board 1 and convert it into a miniLED video signal, and then send it to the LED display module 31 and forward it to other external display devices for display.

[0058] Specifically, such as Figure 2As shown, the LED controller 2 is equipped with a video processing module 21 and a network module 22. The video processing module 21 is connected to the network module 22. The network module 22 is connected to the LED display module 31 via a network cable and is also connected to the control host 4 via a network cable. The network module 22 receives network signals from the control host 4 and decodes them into control signals, and then sends the control signals to the video processing module 21. The network module 22 also encodes HDMI video signals into network signals and forwards them to the LED display module 31 and other external display devices.

[0059] Specifically, the video processing module 21 is equipped with an HDMI in interface 211, an HDMI loop interface 212, and a USB interface. The video processing module 21 connects to the cloud control board 1 via the HDMI in interface 211 and the USB interface, respectively. The video processing module 21 receives the HDMI video signal converted by the cloud control board 1 via the HDMI in interface 211, and receives the decoded control signal sent by the control host 4 via the network module 22. Based on the control signal, it processes the HDMI video signal and sends it to the network module 22. In a specific implementation, when the video processing module 21 receives the HDMI video signal sent by the cloud control board 1 and the control signal decoded and forwarded by the network module 22, it processes the video signal according to the control signal, such as scaling or cropping the video signal. The HDMI video signal is transcoded into a miniLED video signal. Then, the screen splitting information of the video signal, i.e., the content and display method displayed on the splicing screen 3, is parsed from the control signal. The HDMI video signal is then transcoded into a miniLED video signal, and the processed miniLED video signal and screen splitting information are sent to the network module 22. The network module 22 sends the miniLED video signal to the LED display module 31 inside the device and other external display devices according to the screen splitting information. It should be noted that the above method is for the LED cloud screen device 52 to split the screen for other non-LED cloud screen devices 52. When there are at least two LED cloud screen devices 52 in the splicing screen 3, the LED cloud screen devices 52 also transmit video signals to other LED cloud screen devices 52 and perform screen splitting.

[0060] Specifically, the video processing module 21 is also connected to the HDMI in interface 211 of other cloud screen devices via the HDMI loop interface 212, so that it can be connected to the LED controller 2 of other cloud screen devices. At this time, multiple LED cloud screen devices 52 are cascaded. The top-level LED cloud screen device 52 receives the control signal from the control host 4 to determine the screen division information of each level of LED cloud screen device 52. This screen division information and video signal are transmitted to each level of LED cloud screen device 52 through cascading. After receiving the screen division information and video signal, the LED controller 2 of each level of LED cloud screen device 52 performs the above-mentioned processing process, and distributes the video signal to other external non-LED cloud screen devices 52 connected to the corresponding LED cloud screen device 52 for display, forming a splicing screen 3 network.

[0061] Example 2

[0062] like Figure 3 As shown, this embodiment provides a cloud screen system, which includes a display module 5, a signal distribution module 6, and a control host 4;

[0063] The display module 5 is network connected to the signal distribution module 6 and the control host 4, respectively.

[0064] The signal distribution module 6 is connected to an external signal source. The signal distribution module 6 is used to receive signals sent by the signal source and distribute them to the corresponding display module 5.

[0065] The control host 4 is used to control the display mode and display content of the display module 5;

[0066] The display module 5 includes a plurality of display unit devices 53 for display, which form a splicing screen 3 structure. At least one display unit device 53 is configured as an LED cloud screen device 52 as described in Embodiment 1 above. The LED cloud screen device 52 is connected to other display unit devices in the splicing screen 3 via a network cable.

[0067] When at least two LED cloud screen devices 52 are configured, one of them is designated as the master control device 51. The master control device 51 is connected to the control host 4 via a network cable and receives control signals sent by the control host 4. Then, the master control device 51 connects to the HDMI in interface 211 of the adjacent LED cloud screen device 52 through its HDMI loop interface 212; the adjacent LED cloud screen device 52 connects to the HDMI in interface 211 of its adjacent unconnected LED cloud screen device 52 through its HDMI loop interface 212; and so on, until all the LED cloud screen devices 52 on the display module 5 are connected in series to form a cascaded structure.

[0068] In a specific implementation, assume that the splicing screen 3 has four LED cloud screen devices 52, namely device A, device B, device C, and device D, with device A adjacent to device B, device B adjacent to device C, and device C adjacent to device D. Device A is used as the main control device 51. The HDMI loop interface 212 of device A's LED controller 2 is connected to the HDMI in interface 211 of device B's LED controller 2, the HDMI loop interface 212 of device B's LED controller 2 is connected to the HDMI in interface 211 of device C's LED controller 2, and the HDMI loop interface 212 of device C's LED controller 2 is connected to the HDMI in interface 211 of device D's LED controller 2. At this point, devices A, B, C, and D are cascaded. Video signals and split-screen information are transmitted sequentially through devices A, B, C, and D, and are displayed in their respective split-screen configurations at each level.

[0069] When only one LED cloud screen device 52 is set up, there is no need to form a cascade structure. It can be used as the main control device 51 to split the screen.

[0071] like Figure 3 As shown, this embodiment provides an LED cloud screen control method, based on a cloud screen system in Embodiment 2 above. The method includes:

[0072] S1: The control host 4 obtains information from the display module 5 and the signal distribution module 6;

[0073] S2: The signal source is connected to the signal distribution module 6 for signal transmission;

[0074] S3: Signal distribution module 6 collects the video signal from the converged signal source and encodes it into a network signal, which is then sent to display module 5;
