[0029] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0030] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0031] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0032] In the description of this application, "multiple" means two or more, unless otherwise expressly and specifically defined.

[0033] Currently, common LCD video wall solutions typically connect the video source device and the display device using ordinary video cables, such as High Definition Multimedia Interface (HDMI) cables and DisplayPort (DP) cables. However, with the increasing number of usage scenarios, some video wall displays require long-distance transmission. In such cases, it is necessary to extend the video cable using fiber optic extenders. This significantly increases the video transmission cost from the source end to the screen end, and also increases the difficulty of wiring and maintenance.

[0034] In view of this, this application proposes a new splicing display system that can reduce the transmission cost of long-distance video transmission from the source end to the screen end in splicing display scenarios.

[0035] To illustrate the technical solution of this application, specific embodiments are described below.

[0036] Please refer to Figure 1 , Figure 1 A schematic diagram of the splicing display system 1 provided in this application is shown.

[0037] The splicing display system 1 may include a video processing device 10 and a display device group 20 connected to the video processing device 10. The video processing device 10 may include at least a video source device 101. The display device group 20 may include multiple displays 201, each display 201 being provided with a driving display panel 2010.

[0038] In embodiments of this application, the video processing device 10 is used to convert video data into network signals and send them to at least one display screen 201 in the display device group 20. The driving display panel 2010 is used to decode the network signals and drive the display screen 201 to display the video signals.

[0039] Specifically, video data refers to data that needs to be displayed by display device group 20. Video source device 101 is a device that provides video data, and can refer to intelligent devices such as computers, mobile phones, video boxes, smart TVs, and servers that can output video signals.

[0040] In some embodiments of this application, the aforementioned video data can be data captured by a camera / camcorder. For example, the video source device 101 can be directly connected to the camera and output the video data captured by the camera in real time. This method can transmit the data captured by the camera / camcorder to the display screen 201 for real-time display. In monitoring scenarios, this method allows users to easily monitor the camera / camcorder's captured images through the display screen 201.

[0041] In other embodiments of this application, the video data can also be video data generated by the video source device 101. For example, the video source device 101 interacts with the user through video processing software and generates video data based on the user's operation. This method can transmit the video data generated by the user through interaction to the display screen 201 for real-time display. In video rendering scenarios, this method facilitates the user's viewing of the display effect of the video rendered by the video processing software on the display screen 201.

[0042] There are no restrictions on how video data is obtained.

[0043] Video data is converted into network signals by video processing device 10. These network signals may include the complete image to be displayed and / or the segmented video displayed by each display screen 201. The complete image to be displayed refers to the full video image displayed by the various display screens 201 in the display device group 20. It is understood that when the various display screens 201 display the full video image, each display screen 201 will display a portion of the complete image to be displayed, and the segmented video displayed by each display screen 201 refers to the corresponding area displayed by the display screen 201 in the complete image to be displayed. The network signal can be transmitted to at least one display screen 201 in the display device group 20 via the network cable between the video processing device 10 and the display device group 20.

[0044] Multiple displays 201 within the display device group 20 can be spliced ​​together. The driver display board 2010 of each display 201 can decode the network signal to obtain a video signal, and parse the corresponding segmented video from the video signal to drive the display 201 to display the segmented video. Subsequently, multiple displays 201 can be spliced ​​together to display the entire image to be shown.

[0045] In the embodiments of this application, in the splicing display system, the video processing device converts video data into network signals and sends them to at least one display screen in the display device group. Then, the driving display boards of each display screen in the display device group can decode the network signals and drive the display screens to display video signals, achieving the effect of splicing display. When the network signal is transmitted over a long distance, it can be directly implemented using a network cable, without the need for transmission through a combination of fiber optic extenders and video cables. This helps to reduce the transmission cost of long-distance video transmission from the source end to the screen end in splicing display scenarios and reduces the difficulty of wiring and maintenance.

[0046] In some embodiments of this application, such as Figure 2 As shown, the video processing device 10 may also include a video transmission device 102 connected to the video source device 101.

[0047] The video source device 101 is used to send video data to the video transmission device 102. The video transmission device 102 is used to convert the video data into a network signal and send it to at least one display screen 201 in the display device group 20.

[0048] The video transmission device 102 may include a transmitting device and / or a switch. The transmitting device may refer to an electronic device such as a transmitting card used for display screen control. A switch is a device that can connect multiple displays to the same signal source, allowing a user to simultaneously drive multiple displays through a single video source device 101. The video transmission device 102 can be directly connected to at least one display 201 in the display device group 20 via a network cable, and can be directly or indirectly connected to each display 201 in the display device group 20, thereby transmitting the network signal corresponding to the video data to the directly connected display 201 via the network cable, and ultimately to each display 201 in the display device group 20.

[0049] In the embodiments of this application, in the splicing display system 1, the video data sent by the video source device 101 is transmitted to at least one display screen 201 in the display device group 20 in the form of a network signal after passing through the transmitting device and / or switch. Then, the multiple display screens 201 spliced ​​together in the display device group 20 can display the whole picture to be displayed and / or the segmented video displayed by each display screen 201, achieving the effect of splicing display. When the network signal is transmitted over a long distance, it can be directly implemented using a network cable, without the need for transmission through a combination of fiber optic extender and video cable. This helps to reduce the video transmission cost from the source end to the screen end in the splicing display scenario and reduce the difficulty of wiring and maintenance.

[0050] In some embodiments of this application, such as Figure 3 As shown, the video source device 101 may be equipped with a video transmission interface. This video transmission interface can refer to video signal interfaces such as HDMI, DP, Digital Visual Interface (DVI), and Video Graphics Array (VGA). The video transmission interface is used to transmit video signals, which are typically transmitted to analog or digital circuits via video cables.

[0051] The video source device 101 can be used to send video signals corresponding to video data to the transmitting device. Specifically, the video source device 101 can convert video data into video signals according to the protocol corresponding to the type of video transmission interface and transmit them. For example, when the video source device 101 is connected to the transmitting device through an HDMI interface, the video source device 101 can transmit HDMI signals to the transmitting device through the HDMI interface and HDMI cable.

[0052] Accordingly, the video transmission device 102 includes a transmitting device connected to the video source device 101 via a video transmission interface and a video cable, and a switch connected to the transmitting device via a network cable. The transmitting device can be used to convert video signals into network signals and send network signals to the switch. The switch can be used to send network signals to the connected display screen 201.

[0053] Specifically, the transmitting device can convert the video signal transmitted by the video source device 101 into a network signal, which can then be used as an input signal for the switch and the display screen 201. The switch can convert the network signal emitted by the transmitting device and send it to the display screen 201 connected to it. In this way, the video data provided by the video source device 101 will be transmitted to the transmitting device via a video cable, where the transmitting device will convert the video signal into a network signal and send it to the display screen 201 via a network cable and the switch, so that the display screen 201 can splice and display the video.

[0054] Figure 3 The method shown is compatible with video source device 101 that cannot use a network transmission interface. Furthermore, since most video sources exist in the form of video signals, and video source device 101 uses a video transmission interface for signal transmission, there is no need for conversion between video and network signals, resulting in higher compatibility with video source device 101.

[0055] In other embodiments of this application, such as Figure 4 As shown, the video source device 101 is equipped with a first network transmission interface. This first network transmission interface can refer to a network signal interface such as an RJ45 (Registered Jack 45) or fiber optic interface. The first network transmission interface is used to transmit network signals, which are typically transmitted via a network cable and over the internet or a local area network.

[0056] The video source device 101 can be used to send network signals to the switch. Specifically, the video source device 101 can convert video data into network signals according to the protocol corresponding to the type of the first network transmission interface and then transmit them.

[0057] Correspondingly, the video transmission device 102 is a switch connected to the video source device 101 via a first network transmission interface and a network cable. The switch can convert the network signal emitted by the video source device 101 and send the network signal to the display screen 201 connected to it. In this way, the video data provided by the video source device 101 will be transmitted to the switch in the form of a network signal via a network cable, and then sent by the switch to each display screen 201 for splicing and display.

[0058] Figure 4 The method shown is compatible with video source device 101 that can use a network transmission interface. Compared to Figure 3 As shown, Figure 4 The method shown can eliminate the need for a transmitting device, which helps to reduce the cost of the splicing display system 1 and the complexity of the wiring.

[0059] In embodiments of this application, the video transmission device 102 can be connected to at least one display screen 201 in the display device group 20 via a network cable.

[0060] Specifically, in some embodiments of this application, the video transmission device 102 is connected to each display screen 201 in the display device group 20. In this case, each display screen 201 in the display device group 20 is used to display based on the network signal transmitted by the video transmission device 102. That is, each display screen 201 is directly connected to the video transmission device 102 via a network cable to display based on the network signal sent by the video transmission device 102.

[0061] For example, such as Figure 5 As shown, the video transmission device 102 is a switch, which can simultaneously connect to and transmit network signals to each display screen 201 in the display device group 20. In this way, each display screen 201 can directly obtain network signals from the switch, and there is no need to establish a data transmission link between the display screens 201 in the display device group 20 through wiring, which helps to reduce the wiring complexity inside the display device group 20.

[0062] In some other embodiments of this application, the display device group 20 includes a first display screen directly connected to the video processing device 10 and a second display screen not directly connected to the video processing device 10. In this case, the first display screen can be used to transmit network signals to the second display screen and also to display based on the network signals transmitted by the video processing device 10. The second display screen can be used to display based on the network signals transmitted by the first display screen.

[0063] In other words, some of the displays 201 (first displays) in the display device group 20 can be directly connected to the video processing device 10, while the remaining displays 201 (second displays) will be indirectly connected to the video processing device 10. The first displays directly connected to the video processing device 10 can display according to the network signals provided by the video processing device 10. The second displays indirectly connected to the video processing device 10 can obtain network signals from the first displays and display according to the network signals provided by the first displays.

[0064] Specifically, in the embodiments of this application, when the video data sent by the video processing device 10 consists of multiple segmented videos, all segmented videos can be acquired through the first display screen, and then the first display screen displays the corresponding segmented video, while the remaining segmented videos are transmitted to the second display screen. This method can reduce the amount of data transmitted between the display screens 201 and the network load, thereby improving data transmission efficiency.

[0065] In addition, in this embodiment, when transmitting segmented video between the displays 201, all segmented videos can be transmitted. This instructs each display 201 to determine its own segmented video based on the identifier or coordinates of the segmented video and then display it. This method can improve the accuracy of transmission and splicing display.

[0066] Understandably, the more interfaces there are, the higher the processing power required, and the higher the processor cost. Indirect connection reduces the number of displays directly connected to the video processing device 10, thereby reducing the number of interfaces on the video processing device 10. This allows the video processing device 10 to use a relatively low-cost processor, helping to reduce the cost of the video wall display system 1.

[0067] Specifically, such as Figure 6 As shown, in some embodiments of this application, the video processing device 10 further includes a video transmission device 102 connected to the video source device 101, and the video transmission device 102 is a transmitting device. In this case, the video source device 101 is connected to the transmitting device and is used to send the video signal corresponding to the video data to the transmitting device.

[0068] Accordingly, there is one first display screen. The transmitting device is used to convert the video signal into a network signal and transmit the network signal to the first display screen.

[0069] In this way, the video data provided by the video source device 101 can be transmitted to the transmitting device via a video cable. The transmitting device converts the video signal into a network signal and transmits it to the first display screen via a network cable. The remaining display screens 201 (second display screens) of the display device group 20 will receive network signals from the first display screen, so that the various display screens 201 can be spliced ​​together for display.

[0070] Specifically, in the embodiments of this application, video source device 101 sends video data to sending device. When the sent video data consists of multiple segmented videos, all segmented videos can be acquired through the first display screen, which then displays the corresponding segmented video and transmits the remaining segmented videos to the second display screen. This method can reduce the amount of data transmitted between the display screens 201 and the network load, thereby improving data transmission efficiency. Alternatively, when transmitting segmented videos between the display screens 201, all segmented videos can be transmitted, instructing each display screen 201 to determine its own segmented video based on its identifier or coordinates and display it. This method can improve the accuracy of transmission and splicing display.

[0071] Since transmitting devices typically appear as boards, with limited processor capabilities and a limited number of interfaces, they employ... Figure 6 In the method shown, the transmitting device only needs to transmit data with a single first display screen, compared to Figure 3 This eliminates the need for a switch to directly interact with the display device group 20, which helps reduce the cost of the splicing display system 1.

[0072] for Figure 5 and Figure 6 As shown, if there are multiple second displays, the first display and each of the second displays can be connected in different ways.

[0073] For details, please refer to Figure 7 In some embodiments of this application, the individual displays 201 in the display device group 20 are cascaded together. In this case, the first display can be used to send network signals to the second display cascaded to itself. Each second display can be used to transmit network signals to the second display cascaded to itself.

[0074] In this scenario, the first display screen acquires all the segmented video from the video processing device 10. It can then display its corresponding segmented video and transmit the remaining segmented video to the cascaded second display screens. Each second display screen can display its corresponding segmented video and transmit the remaining segmented video to the next level of second display screens. This method progressively reduces the amount of data transmitted and the network load, improving data transmission efficiency.

[0075] In addition, when transmitting segmented video between displays 201, all segmented videos can be transmitted. This instructs each display 201 to determine its own segmented video based on its identifier or coordinates and then display it. This method can improve the accuracy of transmission and splicing display.

[0076] In this way, the network signal will be transmitted level by level until it reaches the last level display screen 201. Each display screen 201 only needs to receive network signals from the previous level display screen 201 and send network signals to the next level display screen 201, which is suitable for situations where the display screen 201 itself has a small number of interfaces. This connection method uses the display screen 201 as a signal transmission medium, which can improve the efficiency of network signal transmission and reduce the display latency of video data when the number of interfaces is limited.

[0077] Please refer to Figure 8 In other embodiments of this application, the first display screen is connected to multiple second display screens. In this case, the first display screen can be used to send network signals to each of the connected second display screens.

[0078] In this scenario, the first display screen acquires all the segmented videos. It can then display its corresponding segmented video, and the segmented videos to be displayed on each of the second display screens are transmitted one-to-one, reducing the amount of data transmitted between the display screens 201 and the network load, thus improving data transmission efficiency. Alternatively, the first display screen can transmit all the segmented videos to each of the second display screens, allowing each second display screen to determine its own segmented video based on its identifier or coordinates and display it. This method improves the accuracy of transmission and splicing display.

[0079] In this way, the network signal will be transmitted from the first display screen to each of the second display screens, which is suitable for situations where the first display screen has many interfaces. Each second display screen only needs to receive the network signal from the first display screen and does not need to transmit signals, so the second display screens can use relatively low-cost processors.

[0080] Of course, in other embodiments of this application, the first display screen and each of the second display screens may be connected by... Figure 7 and Figure 8 Combination methods. For example, such as Figure 9 As shown, the first display screen is directly connected to a portion of the second display screens, used to send network signals to the second display screens directly connected to it. Each second display screen directly connected to the first display screen can be used to transmit network signals to the second display screens connected to it. That is, the first display screen is directly connected to a portion of the second display screens, and this portion of the second display screens directly displays according to the network signals provided by the first display screen. The remaining second display screens... Figure 7 In a similar manner, network signals are obtained from other second displays and displayed.

[0081] Figure 6 The video transmission device 102 is shown as a transmitting device. In some embodiments of this application, such as... Figure 10As shown, the video processing equipment includes a video source device 101 and a video transmission device 102 connected to the video source device. The video transmission device 102 is a switch, and the number of first displays is one or more. Correspondingly, each first display is used to transmit network signals to a correspondingly connected second display.

[0082] Specifically, in this embodiment, video source device 101 sends video data to the switch. When the sent video data consists of multiple segmented videos, all segmented videos or the segmented videos of all displays on the same link can be obtained through the first display screen. Then, the first display screen displays its corresponding segmented video, and the remaining segmented videos are transmitted to the second display screen. This method can reduce the amount of data transmitted between the displays 201 and the network load, thereby improving data transmission efficiency.

[0083] In addition, in this embodiment, when transmitting segmented video between displays 201, it can transmit all segmented video or the segmented video of all displays on the link. This instructs each display 201 to determine its own segmented video based on the identifier or coordinates of the segmented video and then display it. This method can improve the accuracy of transmission and splicing display.

[0084] In this way, the video source device 101 provides video data that can be transmitted to the switch via a video cable. The switch converts the video signal into a network signal and transmits it to the first display screen via a network cable. The remaining display screens 201 (second display screens) of the display device group 20 will obtain network signals from the first display screen, so that the various display screens 201 can be spliced ​​together for display.

[0085] Compared to Figure 6 , Figure 10 The method shown uses a switch. Since switches are generally configured with multiple interfaces, this method can support data transmission with multiple first displays at the same time.

[0086] In addition, in some other embodiments of this application, such as Figure 11 As shown, the video source device 101 is used to convert video data into network signals and send them to at least one display screen 201 in the display device group 20.

[0087] In this case, the video source device 101 has a video data encoding function, which is used to encode and convert the video signal into a network signal, transmit the network signal to at least one display screen 201 in the display device group 20 via a network cable, and finally decode the network signal by driving the display panel 2010 and drive the display screen 201 to display the video signal.

[0088] Specifically, the connection relationships between the video source device 101 and each display screen 201 in the display device group 20, as well as the connection relationships between each display screen 201, can be found in [reference needed]. Figures 7-10 The connection relationships and data transmission methods described above can ensure the quality of video data transmission and playback while reducing data transmission and maintenance costs.

[0089] exist Figures 1 to 10 In the splicing display system 1 shown, data transmission between the video processing device 10 and the display device group 20 can be bidirectional. In addition to transmitting video data to the display screen 201 via network signals as described above, in other embodiments of this application, the video source device 101 can also be used to send first control data to at least one display screen in the display device group, and / or read second control data from at least one display screen in the display device group.

[0090] The first control data can be used to control the display screen 201. Based on the first control data, the user can control the display screen 201 to perform actions through the video source device 101, thereby achieving control effects such as powering on, powering off, turning off the screen, and adjusting the brightness of the display screen 201.

[0091] The second control data can be used to read back the current operating status of the display screen 201, such as the temperature and running time of the display screen 201. Based on the second control data, the user can control and monitor the real-time status of the display screen 201 through the video source device 101, so as to control the display screen 201 according to its real-time status.

[0092] In embodiments of this application, each display screen 201 in the display device group 20 can display after receiving a network signal.

[0093] Specifically, such as Figure 12 As shown, in some embodiments of this application, the driver display panel 2010 may include:

[0094] The decoding module is used to decode network signals to obtain video signals;

[0095] The driver module is used to drive the display module to display video signals;

[0096] Display module.

[0097] Specifically, when the network signal includes the entire image to be displayed, the decoding module, after decoding the video signal, can perform image processing to obtain the segmented video to be displayed, and the driver module then drives the display module to display the segmented video. When the network signal includes the segmented video to be displayed on the display screen 201, the decoding module, after decoding the video signal, can directly drive the display module to display the segmented video.

[0098] This application transmits source video data as a network signal, enabling long-distance transmission via a relatively inexpensive network cable, thus solving the cost and maintenance issues associated with long-distance transmission in splicing display scenarios. Simultaneously, existing decoding boxes can be integrated with the display screen 201 as decoding modules, reducing costs while improving the stability of the splicing display system 1.
