[0030] Reference Figure 1 , a multi-screen display system in one embodiment of the present application includes at least one display device 10, the display device 10 includes an embedded main control board 11, at least two screen splitters and at least four display screens, the embedded main control board 11 is connected to at least two of the screen splitters, namely a first screen splitter 12 and a second screen splitter 13; each screen splitter is connected to at least two of the display screens, such as the first screen splitter 12 is connected to a first display screen 14 and a second display screen 15, and the second screen splitter 13 is connected to a third display screen 16 and a fourth display screen 17; the screen splitter is used to split the multimedia signal sent by the embedded main control board 11, and output the split multimedia signal to the display screen connected to the screen splitter, so that the display screen can display the display content corresponding to the multimedia signal.

[0031] The multimedia signal may include at least one of a picture data signal, a video signal, and a video stream signal obtained from a network.

[0032] Optionally, the embedded main control board 11 can also be used to split multimedia signals and send the split multimedia signals to screen splitters (such as the first screen splitter 12 and the second screen splitter 13) connected to the embedded main control board 11 respectively.

[0033] Optionally, the screen splitter may be an electronic device that combines screen splitting technology and is constructed based on FPGA (Field Programmable Gate Array) or IC (integrated circuit).

[0034] Optionally, the screen splitter is integrated with an input interface, an output interface, a decoding processor, a memory and a multi-screen graphics card. The screen splitter is connected to the embedded main control board via the input interface, and the screen splitter is connected to the display screen via the output interface. The input interface and the output interface both include an EDP (embedded DisplayPort) interface, an LVDS (Low Voltage Differential Signaling) interface, a VGA (Video Graphics Array) interface, an HDMI (High Definition Multimedia Interface) interface and / or a MIPI (Mobile Industry Processor Interface) interface (such as a dual MIPI interface - MIPI MIPI).

[0035] It should be understood that the output interface of the embedded main control board 11 for connecting to the screen splitter may also include at least one of an EDP interface, an LVDS interface, a VGA interface, an HDMI interface and a MIPI interface; the input interface for connecting the display screen to the screen splitter may also include at least one of an EDP interface, an LVDS interface, a VGA interface, an HDMI interface and a MIPI interface.

[0036] Optionally, the embedded main control board 11 has at least two output interfaces for connecting to at least two screen splitters.

[0037] In this way, 4K bandwidth output of multimedia signals through the HDMI interface or dual MIPI interface can reduce the delay of data transmission.

[0038] Optionally, the embedded main control board 11 is used to divide the multimedia signal into multiple multimedia signals, and output the divided multimedia signals to each screen splitter (the number of divided signals can correspond to the number of screen splitters connected to the embedded main control board), and then the screen splitter divides the received multimedia signal again and outputs it to the display screen corresponding to the screen splitter (the number of signals divided by each screen splitter can correspond to the number of display screens connected to the screen splitter), and the display screen displays the multimedia content. At this time, the pictures displayed by all the display screens in the display device are spliced into the entire picture of the original input single multimedia signal.

[0039] Optionally, when the embedded main control board 11 obtains a multimedia signal, it can first divide the multimedia signal into multiple multimedia signals (recorded as first signals) according to the number of screen splitters connected to the embedded main control board 11. The number of first signals is equivalent to the number of screen splitters connected to the embedded main control board 11. Taking the number of two screen splitters as an example, the number of first signals is also two at this time, and the pictures that can be displayed by all the first signals are spliced into the entire picture of the initially input multimedia signal.

[0040] Furthermore, the embedded main control board 11 sends the divided multimedia signals to the screen splitters connected to the embedded main control board 11 (each screen splitter receives a different first signal). When each screen splitter receives the multimedia signal sent by the embedded main control board 11, it splits the received multimedia signal again, so that each screen splitter can obtain multiple multimedia signals (the multimedia signal divided again based on the first signal is recorded as the second signal), and sends the multimedia signals obtained after the second division to the display screens connected to the screen splitters (each display screen receives a different second signal). Taking the example of two screen splitters, each connected to two display screens, the number of second signals is four, and the pictures that can be displayed by all the second signals are spliced into the entire picture of the initially input multimedia signal.

[0041] Optionally, when the embedded main control board 11 receives the multimedia signal, it can simultaneously transmit the multimedia signal to the first screen splitter 12 and the second screen splitter 13 (in this case, the multimedia signals received by the first screen splitter 12 and the second screen splitter 13 are the same). When each screen splitter receives the multimedia signal transmitted by the embedded main control board 11, it will split the multimedia signal into multiple multimedia signals and output the split multimedia signals to the display screen connected to the screen splitter, which will then display the multimedia content. At this time, the images displayed by all the display screens connected to each screen splitter are spliced into the entire image of the original input single multimedia signal.

[0042] For example, after splitting the multimedia signal into two multimedia signals, the first screen splitter 12 transmits the two multimedia signals to the first display screen 14 and the second display screen 15 respectively.

[0043] Optionally, when the embedded main control board 11 receives two multimedia signals A and B, it can transmit multimedia signal A to the first screen splitter 12 and transmit multimedia signal B to the second screen splitter 13. The first screen splitter 12 divides multimedia signal A into two display signals (the two are combined into one to form a complete screen), which are displayed on the first display screen 14 and the second display screen 15 respectively; the second screen splitter 13 divides multimedia signal B into two display signals (the two are combined into one to form a complete screen), which are displayed on the third display screen 16 and the fourth display screen 17 respectively.

[0044] Alternatively, when the embedded main control board 11 receives at least two multimedia signals, it transmits these multimedia signals to all the screen splitters. Each screen splitter is used to output each multimedia signal to a different display screen when receiving multiple multimedia signals transmitted by the embedded main control board 11, which is equivalent to each display screen being used to display one multimedia signal.

[0045] Optionally, when the embedded main control board 11 receives at least two multimedia signals, it obtains the display identifier corresponding to each multimedia signal, queries the screen splitter identifier that matches the display identifier, and then transmits each multimedia signal to the screen splitter that matches its display identifier.

[0046] It should be understood that whether the screen splitter splits the multimedia signal depends on the number of multimedia signals it receives simultaneously. That is, the screen splitter can be used to output each multimedia signal to a different display screen when receiving multiple multimedia signals, or it can be used to split a single multimedia signal into multiple multimedia signals when receiving a single multimedia signal, and output the split multimedia signals to the display screen.

[0047] Optionally, the display screen is a touch screen, which is used to obtain a user's operation instruction for displaying content corresponding to the multimedia signal played on the display screen, and transmit the operation instruction to the embedded main control board. Of course, the embedded main control board and the display screen can be directly connected in communication.

[0048] The operation instruction can be a video pause, switch or play instruction, or an advertisement pop-up window click instruction. If the embedded main control board receives an advertisement pop-up window click instruction sent by the display screen, more relevant information of the advertisement corresponding to the advertisement pop-up window is obtained and sent to the display screen for display.

[0049] Optionally, the embedded main control board 11 may further include an external network module, which is used to obtain multimedia signals from a remote device, such as a computer device, a smart phone, etc.

[0050] Optionally, the external network module may include at least one of WiFi, 4G network, 5G network and Ethernet modules.

[0051] Optionally, the embedded main control board 11 can also receive control instructions sent by a remote device through an external network module. In this way, there is no need to add a dedicated data transmission interface to the embedded main control board at the hardware level to achieve multi-split screen display of multimedia signals.

[0052] Reference Figure 2 In one embodiment, the multi-screen display system includes at least two display devices 10, which are connected to each other via Ethernet, and one of the display devices 10 is a master display device (not shown in the figure), and the other display devices are slave display devices (not shown in the figure). The master display device is used to control and supervise the slave display devices.

[0053] Optionally, the multi-screen display system may further include a remote device 20, which communicates with a display device 10 in the multi-screen display system, wherein the display device communicating with the remote device 20 is a master display device (not shown in the figure), and the other display devices are slave display devices (not shown in the figure), and the master display device is used to control and supervise the slave display device.

[0054] Among them, remote devices include smartphones, computer equipment, servers, tablets, etc.

[0055] Optionally, the embedded main control board (referred to as the first main control board) of the master display device further sends control instructions and multimedia signals to the embedded main control board (referred to as the second main control board) of the slave display device.

[0056] It should be understood that the master and slave display devices also include an embedded main control board 11, at least two screen splitters and at least four display screens, and each embedded main control board is connected to at least two of the screen splitters.

[0057] Optionally, when the main display device receives the multimedia signal, in addition to transmitting the multimedia signal to the first screen splitter 12 and the second screen splitter 13 of the local end at the same time (or transmitting the split multimedia signal to the first screen splitter 12 and the second screen splitter 13 of the local end), the multimedia signal can also be transmitted to the second main control board of the slave display device through the first main control board, and the second main control board transmits the multimedia signal to the first screen splitter 12 and the second screen splitter 13 connected to the second main control board (or the second main control board first splits the multimedia signal sent by the first main control board, and then transmits the split multimedia signal). When the screen splitters in all display devices 10 (including master and slave display devices) receive the multimedia signal, they will split the multimedia signal into multiple multimedia signals, and output the split multimedia signals to the display screen connected to the screen splitter, and the display screen will display the multimedia content.

[0058] For example, after splitting the multimedia signal into two multimedia signals, the first screen splitter 12 transmits the two multimedia signals to the first display screen 14 and the second display screen 15 respectively.

[0059] Alternatively, upon receiving at least two multimedia signals, the master display device transmits the multiple multimedia signals to all of its own screen splitters, and transmits the same multiple multimedia signals to the slave display devices, which then transmit the multiple multimedia signals to their corresponding first and second screen splitters 12 and 13. Upon receiving the multiple multimedia signals transmitted by the embedded main control board 11, the screen splitters in all display devices 10 output each multimedia signal to a different display screen, equivalent to each display screen displaying one multimedia signal.

[0060] In this way, there is no need to add a dedicated data transmission interface to the embedded main control board at the hardware level, and the multi-screen display system can be connected to multiple displays, which can maximize the multi-screen display of multimedia signals and meet the user's multi-screen display needs.

[0061] Reference Figure 2 In this embodiment, the multi-screen display system further includes a power supply board 30, to which the embedded main control board 11 of the master display device and the embedded main control board 11 of the slave display device are respectively connected. The embedded main control board 11 of the master display device can send instructions to the embedded main control board 11 of the slave display device via Ethernet, thereby controlling the power supply of the slave display device to be turned off.

[0062] Optionally, the embedded main control board 11 of the master display device has an external network module and a first internal network module, and the embedded main control board 11 of the slave display device has a second internal network module. The external network module is used to communicate with the remote device, and the first internal network module is used to communicate with the second internal network module of the embedded main control board 11 of the slave display device.

[0063] Optionally, the multi-screen display system also includes a communication module ( Figure 2 (not shown), the embedded main control board 11 of the main display device is connected to the communication module through the external network module, and is connected to the remote device through the communication module.

[0064] Optionally, the communication module includes at least one of a mobile network module (4G / 5G network module), a WiFi module and an Ethernet module.

[0065] The first intranet module of the master display device is connected to the second intranet module of the slave display device.

[0066] Optionally, the main display device acts as a server to receive command information and multimedia signals sent from the external network. The embedded main control board 11 of the main display device can use AndServer or KSWEB server; among them, the first intranet module and the second intranet module can communicate using methods such as Socket, WebSocket, nodejs and adb.

[0067] This eliminates the need for remote devices to manage each control panel. Instead, all control panels can be controlled by simply controlling the embedded control panel in the main display device. Furthermore, the control panels are connected via Ethernet, resulting in highly efficient file transfers.

[0068] Reference Figure 3 In one embodiment, the multi-screen display system includes a display device, the display device includes an embedded main control board, a screen splitter, and a display screen, the embedded main control board is connected to at least two of the screen splitters, and each screen splitter is connected to at least two of the display screens; the control method of the multi-screen display system includes:

[0069] Step S10: The embedded main control board obtains the multimedia signal.

[0070] In this embodiment, the multimedia signal obtained by the embedded main control board may be sent by a remote device, stored in a memory of the embedded main control board, or obtained from a multimedia transmission channel such as an optical fiber.

[0071] Step S20: Send the multimedia signal to each screen splitter, so that the screen splitter splits the multimedia signal sent by the embedded main control board, and outputs the split multimedia signal to the display screen connected to the screen splitter.

[0072] Optionally, when the embedded main control board receives the multimedia signal, it can transmit the multimedia signal to the first screen splitter and the second screen splitter at the same time (in this case, the multimedia signal received by the first screen splitter and the second screen splitter is the same). When each screen splitter receives the multimedia signal transmitted by the embedded main control board, it will split the multimedia signal into multiple multimedia signals, and output the split multimedia signals to the display screen connected to the screen splitter, and the display screen will display the multimedia content. At this time, the images displayed by all the display screens connected to each screen splitter are spliced into the entire image of the original input single multimedia signal.

[0073] For example, after the first screen splitter splits the multimedia signal into two multimedia signals, the first screen splitter transmits the two multimedia signals to the first display screen and the second display screen respectively.

[0074] Optionally, when the embedded main control board receives two multimedia signals A and B, it can transmit multimedia signal A to the first screen splitter and transmit multimedia signal B to the second screen splitter. The first screen splitter divides multimedia signal A into two display signals (the two signals are combined into one to form a complete screen), which are displayed on the first display screen and the second display screen respectively; the second screen splitter divides multimedia signal B into two display signals (the two signals are combined into one to form a complete screen), which are displayed on the third display screen and the fourth display screen respectively.

[0075] Alternatively, when the embedded main control board receives at least two multimedia signals, it transmits these multimedia signals to all the screen splitters. Each screen splitter is configured to output each multimedia signal to a different display screen upon receiving multiple multimedia signals transmitted by the embedded main control board, which is equivalent to each display screen being configured to display one multimedia signal.

[0076] Optionally, when the embedded main control board receives at least two multimedia signals, it obtains the display identifier corresponding to each multimedia signal, queries the screen splitter identifier that matches the display identifier, and then transmits each multimedia signal to the screen splitter that matches its display identifier.

[0077] It should be understood that whether the screen splitter splits the multimedia signal depends on the number of multimedia signals it receives simultaneously. That is, the screen splitter can be used to output each multimedia signal to a different display screen when receiving multiple multimedia signals, or it can be used to split a single multimedia signal into multiple multimedia signals when receiving a single multimedia signal, and output the split multimedia signals to the display screen.

[0078] In this way, multi-split screen display of multimedia signals can be achieved without adding a dedicated data transmission interface to the embedded main control board at the hardware level.

[0079] In one embodiment, if Figure 4 As shown in the above Figure 3 Based on the embodiment shown, the control method of the multi-screen display system further includes:

[0080] S30, dividing the multimedia signal into multiple multimedia signals, wherein the number of divided multimedia signals corresponds to the number of screen splitters connected to the embedded main control board;

[0081] S31 uses the divided multimedia signal as a multimedia signal sent to each screen splitter.

[0082] In this embodiment, the embedded main control board is used to divide the multimedia signal into multiple multimedia signals, and output the divided multimedia signals to each screen splitter (the number of divided signals can correspond to the number of screen splitters connected to the embedded main control board), and then the screen splitter divides the received multimedia signal again and outputs it to the display screen corresponding to the screen splitter (the number of signals divided by each screen splitter can correspond to the number of display screens connected to the screen splitter), and the display screen displays the multimedia content. At this time, the pictures displayed by all the display screens in the display device are spliced into the entire picture of the original input single multimedia signal.

[0083] Optionally, when the embedded main control board receives the multimedia signal, it can first divide the multimedia signal into multiple multimedia signals (recorded as first signals) according to the number of screen splitters connected to the embedded main control board. The number of first signals is equivalent to the number of screen splitters connected to the embedded main control board. Taking the number of two screen splitters as an example, the number of first signals is also two at this time, and the pictures that can be displayed by all the first signals are spliced into the entire picture of the initially input multimedia signal.

[0084] Furthermore, the embedded main control board sends the divided multimedia signal to the screen splitters connected to the embedded main control board (each screen splitter receives a different first signal accordingly). When each screen splitter receives the multimedia signal sent by the embedded main control board, it will split the received multimedia signal again, so that each screen splitter can obtain multiple multimedia signals (the multimedia signal divided again based on the first signal is recorded as the second signal), and the multimedia signals obtained after the second split are sent to the display screens connected to the screen splitter (each display screen receives a different second signal accordingly). Taking the example of two screen splitters and each screen splitter connected to two display screens, the number of second signals is four at this time, and the pictures that can be displayed by all the second signals are spliced into the entire picture of the initially input multimedia signal.

[0085] In this way, after using the embedded main control board to split the multimedia signal, the split multimedia signal is split again using the screen splitter, which greatly increases the number of split screens and can meet the user's multi-split screen display needs to a greater extent.

[0086] In one embodiment, if Figure 5 As shown in the above Figures 3 and 4 Based on the embodiment of the present invention, the multi-screen display system includes at least two display devices, the display devices are connected via Ethernet, one of the display devices is a master display device, and the other display devices are slave display devices, the master display device is used to control and supervise the slave display devices; the control method of the multi-screen display system also includes:

[0087] Step S40: Send the multimedia signal to the embedded main control board of the slave display device, so that the embedded main control board of the slave display device divides the multimedia signal into multiple multimedia signals, and sends the divided multimedia signals to the screen splitter connected to the embedded main control board of the slave display device respectively.

[0088] In this embodiment, the embedded main control board of the master display device (referred to as the first main control board) further sends control instructions and multimedia signals to the embedded main control board of the slave display device (referred to as the second main control board).

[0089] It should be understood that the master and slave display devices also include an embedded main control board, at least two screen splitters and at least four display screens, and each embedded main control board is connected to at least two of the screen splitters.

[0090] Optionally, when the main display device receives the multimedia signal, in addition to transmitting the multimedia signal to the first screen splitter and the second screen splitter at the same time at this end (or transmitting the split multimedia signal to the first screen splitter and the second screen splitter at this end), it can also transmit the multimedia signal to the second main control board of the slave display device through the first main control board, and the second main control board transmits the multimedia signal to the first screen splitter and the second screen splitter connected to the second main control board (or the second main control board first splits the multimedia signal sent by the first main control board, and then transmits the split multimedia signal).

[0091] When the screen splitter in all display devices (including master and slave display devices) receives a multimedia signal, it will split the multimedia signal into multiple multimedia signals, and output the split multimedia signals to the display screen connected to the screen splitter, which will display the multimedia content.

[0092] Alternatively, upon receiving at least two multimedia signals, the master display device transmits the multiple multimedia signals to all of its own screen splitters, and transmits the same multiple multimedia signals to the slave display devices, which then transmit the multiple multimedia signals to their corresponding first and second screen splitters. Upon receiving the multiple multimedia signals transmitted by the embedded main control board, the screen splitters in all display devices output each multimedia signal to a different display screen, equivalent to each display screen displaying one multimedia signal.

[0093] In this way, there is no need to add a dedicated data transmission interface to the embedded main control board at the hardware level, and the multi-screen display system can be connected to multiple displays, which can maximize the multi-screen display of multimedia signals and meet the user's multi-screen display needs.

[0094] In addition, the present application also provides a computer-readable storage medium, the computer-readable storage medium including a control program for a multi-screen display system. When executed by a processor, the control program for the multi-screen display system implements the steps of the multi-screen display system control method described in the above embodiment. It will be understood that the computer-readable storage medium in this embodiment can be a volatile readable storage medium or a non-volatile readable storage medium.

[0095] Those skilled in the art will understand that all or part of the processes in the above-mentioned embodiment methods can be implemented by instructing the relevant hardware through a computer program, and the computer program can be stored in a non-volatile computer-readable storage medium. When the computer program is executed, it can include the processes of the embodiments of the above-mentioned methods. Among them, any reference to memory, storage, database or other media provided in this application and used in the embodiments may include non-volatile and / or volatile memory. Non-volatile memory may include read-only memory (ROM), programmable ROM (PROM), electrically programmable ROM (EPROM), electrically erasable programmable ROM (EEPROM) or flash memory. Volatile memory may include random access memory (RAM) or external cache memory.
