The control module 110 is configured to calculate and obtain a partial display range and a device number corresponding to each of the plurality of rotary display devices 120 based on the acquired screen grouping manner. The control module 110 is configured to send the partial display range and the device number corresponding to each of the plurality of rotary display devices 120 and the output video to be played to each of the plurality of rotary display devices 120, so that each of the rotary display devices 120 displays a corresponding partial video in the video to be played in the partial display range based on the partial display range and the device number corresponding to the rotary display device 120, so as to display the video to be played in the group screen display area. The efficiency of the preparation work before the rotary display equipment is spliced is greatly improved. Low cost and wide application.
In this embodiment, each of the rotary display devices includes a serial interface. The plurality of rotary display devices are serially cascaded through a serial interface. The data transmission rate is improved.
In this embodiment, the plurality of rotary display devices is at least three rotary display devices.

For example, an FPGA chip is included in each rotary display device. And the FPGA chip in each rotary display device 120 cuts the received video to be played based on the partial display range and the device number corresponding to the rotary display device 120, and displays the corresponding cut partial video in the partial display range so as to display the video to be played in the group screen display area.

It is understood that the screen assembly may be overlapped or not overlapped between the rotary display devices, and the present invention is not limited to the combination.
As an embodiment, referring to fig. 3, the control module 110 is a control core expansion board 112. The control core extension board 112 is connected to one rotary display device 120 of the plurality of rotary display devices 120. The control core expansion board 112 is used for wireless communication connection with the terminal 200. The control core expansion board 112 is configured to send the received partial display ranges and device numbers corresponding to the multiple rotary display devices 120 sent by the terminal 200 to each of the rotary display devices 120, where the partial display ranges and device numbers corresponding to the multiple rotary display devices 120 are calculated and obtained by the terminal 200 based on the acquired screen grouping mode. The control core expansion board 112 is configured to decode the received video to be played sent by the terminal 200, and send the decoded video to be played to each of the rotary display devices 120, so that each of the rotary display devices 120 displays a corresponding portion of the decoded video to be played in the portion display range based on the respective corresponding portion display range and the device number corresponding to the rotary display device 120, so as to display the video to be played in the group screen display area. All the rotary display devices only need to play the corresponding part of video, and extra decoding time is not needed to be added between the rotary display devices, so that time delay which possibly occurs can be greatly reduced, and a plurality of rotary display devices can be completely synchronized.
In this embodiment, the terminal 200 may be a terminal device such as a PC (personal computer) computer, a tablet computer, a mobile phone, a notebook computer, a smart television, a set-top box, or a vehicle-mounted terminal. The terminal 200 is provided with third party application software for controlling the rotary display device to play video.

In the present embodiment, the control core expansion board 112 includes a processor, a memory, a serial communication interface, and a wireless communication module. The processor is electrically connected with the memory, the serial communication interface and the wireless communication module respectively. The control core expansion board 112 is configured to be connected to the terminal 200 through the wireless communication module in a wireless communication manner. The control core expansion board 112 is connected to one of the plurality of rotary display devices 120 through the serial communication interface.
Optionally, the wireless communication module includes one of a WIFI module and a bluetooth module.

The low-power design is adopted, and the battery can be used for supplying power, and the external power supply can also be used.
For example, taking a control core expansion board as an example, when the whole system works, all the rotary display devices are cascaded according to a preset screen combination mode, the device numbers of all the rotary display devices connected in series are set through terminal control software, and each rotary display device is assigned with a corresponding device number according to the spatial position of each rotary display device, and the spatial positions can be arranged randomly. And the video to be played is automatically divided into a plurality of blocks in the terminal software, and the blocks are respectively corresponding to different equipment numbers, so that the rotary display equipment corresponding to the equipment numbers plays the corresponding partial video in the display range of the corresponding part. And the terminal control software plays the video in the group screen display area.
The partial display range may refer to a display resolution coordinate range. After the terminal obtains and determines the screen assembly mode, the screen assembly mode is set in the upper computer software in the terminal, the rotary display devices are numbered, then video is imported, the upper computer automatically calculates the display resolution coordinate range of the video to be displayed corresponding to each rotary display device according to the screen assembly mode, as shown in fig. 4, taking the screen assembly mode of (b) in fig. 2 as an example, and fig. 4 shows the mode of cutting video pictures: the upper computer cuts the video with the equipment number (1) into a normal round shape, and cuts the video with the equipment number (2) into a shape with overlapping parts removed. After finishing cutting, the terminal transmits the video with complete resolution, the equipment numbers of each rotary display equipment and the corresponding display resolution coordinate ranges to the rotary display equipment through the control core expansion board by WiFi or Bluetooth.
That is, the video with complete resolution is transmitted from the terminal to the memory of the control core expansion board through WiFi, and after the uploading is completed, the terminal can be used to control the playing of the video through software. When the video is played, the control core expansion board outputs complete high-resolution video, and the video signal is transmitted to each rotary display device connected in series in the system; and meanwhile, the control core expansion board also outputs control signals, so that the FPGA in each rotary display device cuts the received decoded video to be played based on the control signals, the display resolution coordinate range and the device number corresponding to the rotary display device, and displays the cut corresponding part of video in the part of display range so as to display the video to be played in the group screen display area. For the edge of the cut video, the FPGA in the rotary display device can also carry out gradual fading treatment so as to ensure that the video can be naturally displayed when spliced among different rotary display devices. All the rotary display devices together form a complete video picture before clipping.
