[0056] In this embodiment, the display device 200 generally refers to a device with screen display and data processing capabilities. For example, the display device 200 includes, but is not limited to, smart TVs, mobile terminals, computers, monitors, advertising screens, wearable devices, virtual reality devices, augmented reality devices, etc.

[0057] Figure 1 This is a schematic diagram illustrating an operational scenario between a display device and a control device provided in some embodiments of this application. For example... Figure 1As shown, a user can operate the display device 200 via touch operation, a mobile terminal 300, and a control device 100. The control device 100 receives user input commands and converts them into control commands that the display device 200 can recognize and respond to. For example, the control device 100 can be a remote control, a stylus, a gamepad, etc.

[0058] The mobile terminal 300 can function as a control device for human-computer interaction between the user and the display device 200. It can also function as a communication device for establishing a communication connection with the display device 200 and exchanging data. In some embodiments, the mobile terminal 300 can have software applications installed on it and communicate with the display device 200 via network communication protocols to achieve one-to-one control and data communication.

[0062] Figure 2 Provided for some embodiments of this application Figure 1 Hardware configuration block diagram of display device 200.

[0063] In some embodiments, the display device 200 may include at least one of a tuner 210, a communication device 220, a detector 230, a device interface 240, a controller 250, a display 260, an audio output interface 270, a memory, a power supply, and a user interface 280.

[0064] The display 260 can be any one of a first display and at least one second display, and the first display and at least one second display can be spliced ​​together to form the display device 200. For example, the first display and at least one second display can be spliced ​​together in rows and columns to form a rectangular display device with a larger size.

[0065] In some embodiments, detector 230 is used to acquire signals from the external environment or to interact with the outside world. For example, detector 230 includes a light receiver, a sensor for acquiring ambient light intensity; or, detector 230 includes an image acquisition device, such as a camera, which can be used to acquire external environmental scenes, user attributes, or user interaction gestures; or, detector 230 includes a sound acquisition device, such as a microphone, for receiving external sounds.

[0066] In some embodiments, the display 260 includes display function components for presenting images and driving components for driving image display. The display 260 is used to receive and display image signals output from the controller 250. For example, the display 260 can be used to display video content, image content, menu control interface components, and user control UI interfaces, etc.

[0067] In some embodiments, the communication device 220 is a component used to communicate with external devices or the server 400 according to various communication protocol types. The display device 200 may have multiple communication devices 220 depending on the supported communication methods. For example, when the display device 200 supports wireless network communication, it may have a communication device 220 with WiFi functionality. When the display device 200 supports Bluetooth connectivity, it needs to have a communication device 220 with Bluetooth functionality.

[0068] The communication device 220 enables the display device 200 to communicate with external devices or the server 400 via wireless or wired connections. Wired connections utilize data cables, interfaces, or other components to connect the display device 200 to external devices. Wireless connections utilize wireless signals or wireless networks. The display device 200 can directly establish a connection with external devices or indirectly through gateways, routers, or other connection devices.

[0069] In some embodiments, the controller 250 may be coupled to the display 260 and is capable of controlling the display 260 to perform corresponding operations. The controller 250 may include at least one of a central processing unit, a video processor, an audio processor, a graphics processor, and a power processor, and provide a first to an nth interface for input / output. The controller 250 controls the operation of the display device and responds to user operations through various software control programs stored in memory. The controller 250 controls the overall operation of the display device 200.

[0070] In some embodiments, in the first display and at least one second display of the display device 200, each display 260 may be coupled to a corresponding controller 250, that is, there is a one-to-one correspondence between the display 260 and the controller 250, and the controller 250 is used to control the corresponding display 260 to perform corresponding operations.

[0071] In some embodiments, in the first display and at least one second display of the display device 200, each display may include a receiving interface and an output interface. The first display and at least one second display may be connected sequentially. For example, in the connection path between the first display and at least one second display, the output interface of the previous display may be connected to the receiving interface of the next display.

[0072] The receiving interface is the interface on the monitor used to receive external signals or data, and may include HDMI (High Definition Multimedia Interface), VGA (Video Graphics Array), DVI (Digital Visual Interface), etc. The output interface is the interface on the monitor used to output signals or data, and may include HDMI, etc.

[0073] In the first display and at least one second display of the display device 200, each display can receive signals or data through a receiving interface and forward the received signals or data to the receiving interface of the next connected display through an output interface, and then the next display forwards the data to the display after that through its output interface. In other words, based on the interface connection relationship between the first display and at least one second display, the signals or data received by the first display can be synchronously transmitted to other connected second displays.

[0074] For example, when the first display receives video data, the video data can be synchronized to all other connected second displays, so that the video data can be played on all displays of the display device 200.

[0075] In some embodiments, the controller 250 and the tuner 210 may be located in different separate devices, that is, the tuner 210 may also be located in an external device of the main device where the controller 250 is located, such as an external set-top box.

[0076] In some embodiments, a user can input user commands through a graphical user interface (GUI) displayed on a display 260, and the user input interface receives user input commands through the graphical user interface (GUI).

[0077] In some embodiments, the audio output interface 270 can be a built-in speaker of the display device 200 or an external audio output device connected to the display device 200. For the external audio output device connected to the display device 200, the display device 200 may also be provided with an external audio output terminal, through which the audio output device can be connected to the display device 200 to output sound from the display device 200.

[0078] In some embodiments, the user interface 280 can be used to receive instructions from user input.

[0079] To enable user interaction, in some embodiments, the display device 200 may run an operating system. The operating system is a computer program used to manage and control the hardware and software resources of the display device 200. The operating system can control the display device to provide a user interface; for example, the operating system can directly control the display device to provide a user interface, or it can provide a user interface by running an application. The operating system also allows users to interact with the display device 200.

[0080] It should be noted that the operating system can be a native operating system based on a specific operating platform, a third-party operating system that is deeply customized based on a specific operating platform, or an independent operating system specifically developed for display devices.

[0081] For the purpose of detailing the display control method provided in the embodiments of the present invention, Figure 3 The flowchart shown is a display control method provided by an embodiment of the present invention, which can be applied to... Figure 1 The display device 200 shown.

[0082] The display device 200 can be composed of a first display and at least one second display connected sequentially. For example, the first display and at least one second display can be spliced ​​together to form a larger display device 200. The first display is coupled to a first controller, and the second display is coupled to a second controller. The first display is the first display in the connection path between the first display and at least one second display, and the second display is any one of the other displays in the display device 200 besides the first display.

[0083] In this embodiment, the first controller is used to control the first display to show the image or perform corresponding operations, and the second controller is used to control the second display to show the image or perform corresponding operations. There is a one-to-one correspondence between the second display and the second controller.

[0084] Both the first and second displays can be used to display a user interface, which is the interaction interface between the user and the display device 200. The user can send commands to the display device 200 via remote control or touch screen to control the display device to perform a certain task. The user interface has a sophisticated interactive design, allowing the user to easily complete a task. For example, the user interface can be a video playback interface, where the user can control the first display and any one or more second displays to display the video playback interface and play video data via remote control or touch screen.

[0085] In some embodiments, each of the first display and at least one second display may include a receiving interface and an output interface. The first display and at least one second display are connected sequentially, and in this case, on the connection path between the first display and at least one second display, the output interface of the preceding display may be connected to the receiving interface of the following display.

[0086] In some embodiments, the receiving interface may include an HDMI input interface, and the output interface may include an HDMI output interface. The HDMI input interface of the monitor can be used to receive audio and video signals from external devices and transmit these signals to other devices, such as other monitors connected to the monitor. During connection, each monitor can be connected via an unused pin of either the HDMI input or HDMI output interface to enable signal and data transmission between the monitors.

[0087] Since the HDMI interface is a commonly used interface for transmitting audio and video signals in display devices, transmitting signals and data through the HDMI input and output interfaces can reduce the number of connection interfaces between various monitors in the display device, making the installation and maintenance of the display device more convenient.

[0088] To illustrate the connection method of multiple displays in this embodiment Figure 4 A schematic diagram of a display device provided by an embodiment of the present invention is shown, such as... Figure 4 As shown, taking a 2*2 display device as an example, the display device consists of 4 monitors, namely monitor 1, monitor 2, monitor 3 and monitor 4, and these 4 monitors are arranged in a rectangular shape. Each monitor includes a receiving interface and an output interface, and the output interface of the previous monitor is connected to the receiving interface of the next monitor. That is, the monitors are connected in a loop through the interfaces. For example, the output interface 1 of monitor 1 is connected to the receiving interface 2 of monitor 2, the output interface 2 of monitor 2 is connected to the receiving interface 3 of monitor 3, and the output interface 3 of monitor 3 is connected to the receiving interface 4 of monitor 4.

[0089] In some embodiments, such as Figure 4In the display device shown, the input interface 1 of the display 1 can be connected to a peripheral device to receive media resources transmitted by the peripheral device.

[0090] In order to power the various displays in the display device, in some embodiments, such as Figure 4 As shown, each display may include a power interface, and each display's power interface may include a power input interface and a power output interface. For example, display 1 includes a power input interface 1 and a power output interface 1, and display 2 includes a power input interface 2 and a power output interface 2, etc.

[0091] The monitors can be connected in a loop through the power interface. That is, the power input interface 1 of monitor 1 is connected to an external power source, the power output interface 1 is connected to the power input interface 2 of monitor 2, the power output interface 2 of monitor 2 is connected to the power input interface 3 of monitor 3, and the power output interface 3 of monitor 3 is connected to the power input interface 4 of monitor 4, thereby supplying power to each monitor through the power interface.

[0092] It should be understood that Figure 4 The number and arrangement of displays in the illustrated display device are for illustrative purposes only. Depending on the actual display requirements, the display device can have any number of displays, and the arrangement of each display can be set to any shape. This embodiment does not impose any specific limitations on this.

[0093] In a multi-monitor connection path, the first monitor is the first monitor, and any monitor other than the first monitor is the second monitor. Figure 4 Taking the display device shown as an example, display 1 is the first display, and display 2, display 3 and display 4 are all second displays.

[0094] According to the display control method provided in the embodiments of the present invention, a display device can receive a mode setting instruction through a first controller, and based on the interface connection relationship between the first display and at least one of the second displays, transmit the mode setting instruction to a target controller coupled to the target display indicated by the mode setting instruction, so that the target controller sets the control mode of the target display to a target control mode, i.e., a separate control mode or a unified control mode; after setting the control mode of the target display to the target control mode, the first controller can transmit media resources to the target controller based on the interface connection relationship between the first display and at least one of the second displays, so that the target controller controls the target display to play media resources based on the target control mode of the target display.

[0095] By applying this solution, a mode setting command can be received by a first controller coupled to a first display. Then, based on the interface connection relationship between the first display and at least one second display, the mode setting command is transmitted to the target controller coupled to the target display indicated by the mode setting command. This sets the target display to the target control mode, i.e., individual control mode or unified control mode. When media resources are received, the target display can be controlled to play media resources in individual control mode or unified control mode. This enables individual or unified control of multiple displays, improving the operational flexibility of the display device and the diversity of the displayed screen.

[0096] like Figure 3 As shown, the first controller is configured to perform the following steps S310 to S330:

[0097] Step S310: Receive mode setting command.

[0098] The mode setting instruction can be used to indicate a target control mode for any one or more of the at least one second display. The target control mode can include an individual control mode or a unified control mode. Specifically, an individual control mode refers to a mode that controls the display or operation of a single display among the first display and at least one second display, while a unified control mode controls the display or operation of multiple displays among the first display and at least one second display. In other words, when a display is in individual control mode, the user can only operate that display without affecting the operation of other displays. When a display is in unified control mode, the user can perform a one-time operation on all displays in the display device, without needing to operate each display individually.

[0099] In this embodiment, to enhance the playback flexibility of the display device, the user can set the control mode of any one or more displays in the display device by inputting mode setting commands.

[0100] Depending on the method of controlling the display device, the user can send mode setting commands to the first controller in various ways. For example, when the display device supports touch control, the user can control the first display to open the mode setting interface through touch operation, and then select the target control mode of one or more second displays in the mode setting interface. For example, the user can select the panel_id of a certain second display in the mode setting interface, thereby triggering a mode setting command to control that second display individually. Alternatively, the user can enter the number "0" in the mode setting interface, thereby triggering a mode setting command to control all displays uniformly, that is, the first display and all second displays.

[0101] In some embodiments, the first display may be coupled to an instruction receiver, and the first controller may receive mode setting instructions through the instruction receiver.

[0102] The command receiver can be a remote control signal receiver or a voice receiver, such as a microphone. Taking an infrared remote control signal receiver as an example... Figure 5 This embodiment shows a schematic diagram of the structure of an infrared remote control signal receiver. Figure 5 As shown, the infrared remote control signal receiver 500 includes two ground pins (GND1 and GND4), one power supply pin (VCC), one signal output pin (OUT), and one standby voltage input pin (VS). The signal output pin (OUT) is connected to the HDMI input interface of the first display and can be used to output the control signal received from the remote control as a digital signal and transmit it to the first controller of the first display for further processing.

[0103] For example, when a user inputs a command to open the mode setting interface via a remote control, the first controller can receive the control signal sent by the remote control via an infrared remote control signal receiver, thereby controlling the first display to show the mode setting interface. In the mode setting interface, the user can trigger the selection of a corresponding control mode for one or more second displays via buttons on the remote control, such as a single control mode or a unified control mode, thereby generating a mode setting command.

[0104] In some embodiments, the user may also record voice commands via microphone, such as commands to control the first display to show the mode setting interface, so that the first display switches to the mode setting interface. Then, the user may further input or select the corresponding control mode via remote control or voice receiver, so that the first controller triggers the generation of mode setting commands.

[0105] In some embodiments, each of the first display and at least one second display can be coupled to a corresponding instruction receiver. In this case, in order to achieve individual control of each display and avoid the first display and at least one second display responding to the control signal of the remote control at the same time, control codes for the first display and each second display can be set. When controlling the first display or a certain second display, the user can set the control code of the remote control to the control code of the corresponding display, so as to use the remote control to control the display without affecting other displays.

[0106] Step S320: Based on the interface connection relationship between the first display and at least one second display, transmit the mode setting command to the target controller coupled to the target display indicated by the mode setting command, so that the target controller sets the control mode of the target display to the target control mode.

[0107] The interface connection relationship between the first display and at least one second display refers to the relationship between the data transmission interfaces of the first display and at least one second display. For example, it could be the connection relationship between the receiving and output interfaces of each display. For instance, in the connection path between the first display and at least one second display, the output interface of the preceding display can be connected to the receiving interface of the following display. At least one second display may include a target display.

[0108] Based on the interface connection relationship between the first display and at least one of the second displays, the transmission path of signals or data between the displays can be determined. Therefore, in order to control the second display, the first controller can execute step S321, that is, based on the interface connection relationship between the first display and at least one of the second displays, synchronize the mode setting command to the target controller coupled to the target display indicated by the mode setting command. For example, when the first controller receives the mode setting command, it can parse the mode setting command, determine the second display indicated by the mode setting command, take it as the target display, and then, according to the interface connection relationship between the first display and at least one of the second displays, transmit the mode setting command to the target controller coupled to the target display through the receiving interface and output interface of the corresponding display.

[0109] When the target controller receives the mode setting instruction, it can set the control mode of the target display to the target control mode, such as the individual control mode or the unified control mode, by executing step S322.

[0110] To enable the processing and forwarding of mode setting instructions, in some embodiments, reference is made to... Figure 6 As shown, when each of the first display and at least one second display receives a mode setting command, it can amplify the mode setting command and then transmit it to the controller of that display for processing. It can also transmit the mode setting command to the output interface of that display for forwarding.

[0111] In some embodiments, each of the first display and at least one second display may include a receiving interface and an output interface, thereby, referring to Figure 7 As shown, the first controller can execute the following methods:

[0112] Step S710: Based on the interface connection relationship between the first display and at least one of the second displays, the control mode setting command is output through the output interface of the first display and connected to the next second display through the receiving interface of the next second display.

[0113] The next second display is a second display that is directly connected to the first display among at least one second display.

[0114] For example, in such Figure 4 In the display device shown, the first controller, i.e. the controller corresponding to display 1, can parse the mode setting command, determine the target display indicated by the mode setting command, and then, when the target display includes any one of the second displays, such as display 2, display 3, and display 4, according to the interface connection relationship between the first display and at least one of the second displays, the mode setting command is transmitted through the output interface 1 of display 1 to the directly connected next second display, i.e., display 2. Display 2 receives the mode setting command through the receiving interface 2.

[0115] Step S720: The mode setting command is output through the output interface of the next second display via the second controller coupled to the next second display, and connected to the next next display via the receiving interface of the next next second display, until the mode setting command is transmitted to the target controller.

[0116] For example, in Figure 4 When display 2 receives a mode setting command, its controller can control it to transmit the command to the next second display (display 3) via output interface 2. This command transmission continues until the corresponding target display receives the mode setting command. Because the target display and target controller are coupled, when all target displays receive the mode setting command, the corresponding target controller will also receive it.

[0117] Using the above method, based on the interface connection relationship between the first display and at least one second display, the mode setting command can be transmitted to all corresponding target controllers, so that the target controllers can receive the mode setting command and set the control mode of the target display according to the mode setting command. This enables the transmission of the mode setting command between multiple displays so as to control the mode of each display.

[0118] After transmitting the mode setting instruction to the target controller, in some embodiments, the second controller may set the control mode of the second display coupled to the second controller to the separate control mode when the target control mode is a separate control mode and the target display indicated by the mode setting instruction is a second display coupled to the second controller; and set the control mode of the second display coupled to the second controller to the unified control mode when the target control mode is a unified control mode.

[0119] For example, when the target display indicated by the mode setting instruction is a second display coupled to the second controller, the second controller is the target controller. At this time, the second controller can parse the mode setting instruction, determine the target control mode, and then, based on the current control mode and the target control mode of the second display coupled to it, if the target control mode is determined to be a separate control mode and the current control mode is a separate control mode, the control mode of the second display coupled to the second controller is kept in the separate control mode. If the target control mode is determined to be a separate control mode and the current control mode is a unified control mode, the control mode of the second display coupled to the second controller is switched to the separate control mode.

[0120] Accordingly, when the target control mode is determined to be a unified control mode and the current control mode is a separate control mode, the control mode of the second display coupled to the second controller is switched to the unified control mode. When both the target control mode and the current control mode are determined to be unified control modes, the control mode of the second display coupled to the second controller is kept to be unified control mode.

[0121] In this way, the second controller can set the control mode of its coupled second display to a separate control mode or a unified control mode. In the separate control mode, the user can operate and control only the second display, while in the unified control mode, the user can operate and control all displays, namely the first display and all second displays. Therefore, the operation flexibility of the display device can be improved, and the display device can also provide a richer and more diverse range of screen display methods.

[0122] In some embodiments, the mode setting instruction can also be used to indicate the target control mode of the first display. In this case, the first controller can also set the control mode of the first display to the individual control mode when the target control mode is the individual control mode and the target display indicated by the mode setting instruction is the first display; and set the control mode of the first display to the unified control mode when the target control mode is the unified control mode.

[0123] For example, when the first controller parses the mode setting instruction and determines the target display indicated by the mode setting instruction and the target control mode of the target display, the first controller can control the first display to set the control mode to a separate control mode or a unified control mode according to the current control mode and the target control mode of the first display.

[0124] In this way, the first controller can set the control mode of the first display to a separate control mode or a unified control mode, allowing the user to operate and control only the first display, or to operate and control the first display and all second displays. Therefore, it can also improve the operational flexibility of the display device and the diversity of screen display.

[0125] After setting the control mode of the first display to either individual control mode or unified control mode, the user can configure the first display. For example, refer to... Figure 8 As shown, the first controller can also perform the following methods:

[0126] Step S810: Receive the first display setting instruction.

[0127] The first display setting instruction can be used to indicate the display parameters of the first display. The display parameters may include the resolution, brightness, contrast ratio, and color depth of the first display.

[0128] For example, a user can control the first display to open the display settings interface through touch operation, and then input or select the corresponding display parameters in the display settings interface to trigger the first display settings command. Alternatively, when the user inputs the command to open the display settings interface through the remote control, the first controller can receive the control signal sent by the remote control through the infrared remote control signal receiver, thereby controlling the first display to display the display settings interface. In the display settings interface, the user can input or select the corresponding display parameters through the buttons on the remote control to generate the first display settings command.

[0129] For example, users can also record voice commands through the microphone, such as commands to set display parameters to specified values, causing the first display to switch to the display settings interface and generate a first display settings command based on the display parameters to be set.

[0130] Step S820: Set the display parameters of the first display according to the first display setting instruction.

[0131] When the first display is in individual control mode or unified control mode, the first controller can set the display parameters of the first display to the corresponding target values ​​according to the target values ​​of the display parameters in the first display setting instruction. In this case, when the first display is in individual control mode, only the display parameters of the first display are updated, and all second displays are in a disabled state with their display parameters remaining unchanged. When the first display is in unified control mode, the display parameters of both the first display and all second displays are updated.

[0132] Therefore, through the above steps S810 to S820, the user can set the display parameters of the first display according to the control modes of the first display and all the second displays, so that the first display can display the screen according to the display parameters set by the user, and in the individual control mode, it will not affect the screen display of the second display, thus enhancing the display flexibility and operation flexibility of the display device, and also improving the operation efficiency.

[0133] After setting the control mode of the second display coupled to the second controller to either a separate control mode or a unified control mode, the user can also configure the second display. For example, refer to... Figure 9 As shown, the first controller can also perform the following methods:

[0134] Step S910: Receive the second display setting instruction.

[0135] The second display setting command can be used to set the display parameters of the second display coupled to the second controller, such as the resolution, brightness, contrast and color depth of the second display.

[0136] Correspondingly, users can also control the second display to open the display settings interface through touch or voice operation, and then enter or select the corresponding display parameters in the display settings interface to trigger the second display settings command. Alternatively, users can control the first display to display the display settings interface through the remote control, and then enter or select the corresponding display parameters through the buttons on the remote control in the display settings interface to generate the second display settings command.

[0137] Step S920: Based on the interface connection relationship between the first display and at least one of the second displays, a second display setting instruction is transmitted to the second controller, so that the second controller sets the display parameters of the second display coupled to the second controller according to the second display setting instruction.

[0138] For example, when the first controller receives the second display setting instruction, step S921 can be executed to transmit the second display setting instruction to the second controller according to the interface connection relationship between the first display and at least one second display, so as to... Figure 4Taking the display device shown as an example, the first controller, i.e. the controller corresponding to display 1, can transmit the second display setting instruction to the next second display, i.e. the receiving interface of display 2, through the output interface 1 of display 1, according to the interface connection relationship between the first display and at least one of the second displays, and transmit the second display setting instruction to the next next second display, i.e. display 3, through the output interface 2, until all the second displays have received the second display setting instruction. Since the second display is coupled to the second controller, when all the second displays have received the second display setting instruction, the corresponding second controller will also receive the second display setting instruction.

[0139] When the second controller receives the second display setting instruction, the second controller can execute step S922 to set the display parameters of the second display coupled to the second controller according to the second display setting instruction. For example, the second controller can parse the second display setting instruction to determine whether the target display indicated by the second display setting instruction includes the second display coupled to itself. If it does, the display parameters of the second display can be set to the target value in the second display setting instruction.

[0140] In this way, users can set the display parameters of any one or more second displays. When displaying images, each second display can also display according to the corresponding display parameters, which can meet the diverse playback needs of users and improve the flexibility of the display device's display.

[0141] Step S330: After the target controller sets the control mode of the target display to the target control mode, the media resources are transmitted to the target controller based on the interface connection relationship between the first display and at least one second display, so that the target controller controls the target display to play the media resources based on the target control mode of the target display.

[0142] Media resources refer to various forms of materials and content used for purposes such as disseminating information, expressing ideas, and providing entertainment. They may include any one or more of text resources, image resources, audio resources, and video resources.

[0143] After setting the control mode of the target display to the target control mode, the first controller can receive media resources. Upon receiving the media resources, the first controller executes step S331 to synchronize the media resources to the target controller according to the interface connection relationship between the first display and at least one second display. This allows the target controller to execute step S332 to control the target display to play the media resources based on the target control mode of the target display.

[0144] For example, when the target control mode of the target display is the individual control mode, the target controller can control the second display to play media resources. At this time, other displays do not play the media resources, but can play other media resources on their own. When the target control mode of the target display is the unified control mode, the first display and all second displays will play media resources. At this time, the target controller can control the target display to play the same media resources as other displays, or it can control the target display to play local media resources according to the position of the target display among the first display and all second displays, thereby realizing the playback of a media resource on multiple displays.

[0145] In order for each second display to acquire media resources, in some embodiments, reference is made to Figure 10 As shown, the first controller can execute the following methods:

[0146] Step S1010: Based on the interface connection relationship between the first display and at least one of the second displays, control the media resources to be output through the output interface of the first display and connected to the next second display through the receiving interface of the next second display.

[0147] The next second display is the second display that is directly connected to the first display among a plurality of second displays.

[0148] For example Figure 4 Taking the display device shown as an example, the first controller, that is, the controller corresponding to the display 1, can transmit the media resources through the output interface 1 of the display 1 to the directly connected second display, that is, the receiving interface 2 of the display 2, according to the interface connection relationship between the first display and at least one second display when receiving media resources.

[0149] Step S1020: The media resources are output through the output interface of the next second display via the second controller coupled to the next second display, and connected to the next next second display via the receiving interface of the next next second display, until the media resources are transmitted to the target controller.

[0150] For example, when display 2 receives media resources, the controller of display 2 can control display 2 to transmit the media resources to the next second display, i.e., display 3, through output interface 2. Command transmission continues in this manner until the target controller coupled to the target display receives the media resources.

[0151] Using the above method, media resources can be transmitted to all corresponding target displays based on the interface connection relationship, so that the target displays can receive the media resources and play them according to the corresponding control mode.

[0152] In some embodiments, after setting the control mode of the first display to a separate control mode, the first controller can also control the first display to play media resources. In this case, when the first display is playing media resources, all second displays will not play media resources. Therefore, the display device can control the first display to play media resources independently, enabling a single display to play media resources without affecting other displays playing other media resources.

[0153] In some embodiments, after setting the control mode of the first display to a unified control mode, refer to Figure 11 As shown, the first controller can also perform the following methods:

[0154] Step S1110: Determine the first screen area of ​​the media resource based on the row and column position of the first display in the first display and at least one second display.

[0155] Wherein, the row and column position of the first display among multiple displays refers to the arrangement position of the first display among all displays, namely the first display and at least one second display, as follows: Figure 4 Taking the display device shown as an example, the first display, namely display 1, is located in the 1st row and 2nd column.

[0156] Based on the row and column position of the first display within the first display and at least one second display, the first screen area corresponding to the media resource can be determined when playing the media resource, for example, in... Figure 4 In the display device shown, since the position of display 1 is in the first row and second column, the first screen area is the lower right corner area of ​​the media resource.

[0157] For example, the display size of the first display in the first display and at least one second display corresponds to the screen size of the first screen area, that is, the larger the display size of the first display in the first display and at least one second display, the larger the screen size corresponding to the first screen area.

[0158] Step S1120: According to the first screen area, perform screen capture processing on the media resource to obtain the first media resource, and control the first display to play the first media resource.

[0159] In order to make the first display only play the content in the first screen area, the first controller can perform screen capture processing on the media resources to obtain the first media resources that only include the first screen area, thereby controlling the first display to play the first media resources.

[0160] In this way, the first controller can control the first display to play media resources in a local area according to its position area in the display device, so as to realize split-screen playback of media resources.

[0161] In some embodiments, after setting the control mode of the second display coupled to the second controller to a separate control mode, the second controller can control the second display coupled to the second controller to play media resources. In this case, while the second display is playing media resources, the first display and other second displays will not play media resources. Therefore, the display device can control the second display to play media resources independently, enabling a single display to play media resources without affecting other displays playing other media resources.

[0162] In some embodiments, after setting the control mode of the second display coupled to the second controller to a unified control mode, refer to Figure 12 As shown, the second controller can perform the following methods:

[0163] Step S1210: Determine the second screen area of ​​the media resource based on the row and column position of the second display in the first display and at least one second display.

[0164] Wherein, the row and column position of the second display in the first display and at least one second display refers to the arrangement position of the second display in the first display and at least one second display, such as... Figure 4 Taking the display device shown as an example, the second display, such as display 2, is located in the 2nd row and 2nd column.

[0165] Based on the row and column position of the second display within the first display and at least one other second display, the second screen area corresponding to the media resource can be determined during media resource playback. For example, in... Figure 4 In the display device shown, since the position of display 2 is in the 2nd row and 2nd column, the second screen area is the upper right corner area of ​​the media resource.

[0166] Step S1220: According to the second screen area, perform screen capture processing on the media resource to obtain the second media resource, and control the second display coupled to the second controller to play the second media resource.

[0167] In order to make the second display only play the content in the second screen area, the second controller can perform screen capture processing on the media resources to obtain the second media resources that only include the second screen area, thereby controlling the second display coupled to the second controller to play the second media resources.

[0168] In this way, the second controller can control the second display coupled to it to play media resources in a local area according to its position area in the display device, thereby realizing split-screen playback of media resources.

[0169] To avoid interference from external devices with the remote control signal, in some embodiments, the first controller can also receive media resources sent by peripheral devices through the receiving interface of the first display.

[0170] The instruction receiver of the first display is connected to any free pin of the HDMI input interface through a shielding circuit, which is used to shield the instruction receiver from interference caused by peripheral devices.

[0171] In some embodiments, the shielding circuit may be equipped with a switch to control whether the shielding circuit function is enabled. Figure 13 A connection diagram of a shielding circuit provided in an embodiment of the present invention is shown, as follows: Figure 13 As shown, the shielding circuit is connected to the power supply. When the power is turned on, the shielding circuit is activated, which enables the control signal pin of the first display to be in a floating state, disconnecting it from external devices and solving the interference of external devices on the control signal.

[0172] In summary, according to the display control method provided in this embodiment, a mode setting instruction can be received by a first controller coupled to a first display. Then, based on the interface connection relationship between the first display and at least one second display, the mode setting instruction is transmitted to the target controller coupled to the target display indicated by the mode setting instruction. This causes the target controller to set the control mode of the target display to the target control mode, i.e., individual control mode or unified control mode. When media resources are received, the target display can be controlled to play media resources according to the individual control mode or unified control mode. This enables individual or unified control of multiple displays, improving the operational flexibility of the display device and the diversity of the display screen.

[0173] In some embodiments of this example, by setting a shielding circuit, the signal interference generated by the peripheral device on the instruction receiver of the first display when the peripheral device inputs media resources can be resolved, thereby improving the operation quality of the display device.

[0174] This invention also provides a display control device, see reference. Figure 14As shown, the display control device 1400 can be applied to a first controller of a display device. The display device is composed of a first display and at least one second display connected in sequence. The first display is coupled to the first controller, and the second display is coupled to the second controller. The first display is the first display on the connection path between the first display and at least one second display. The display control device 1400 may include: a receiving module 1410, which can be used to receive a mode setting instruction. The mode setting instruction is used to indicate a target control mode for any one or more of the at least one second display. The target control mode includes a separate control mode or a unified control mode; a first transmission module 1420, which can be used to transmit the mode setting instruction to the target controller coupled to the target display indicated by the mode setting instruction based on the interface connection relationship between the first display and each of the at least one second display, so that the target controller sets the control mode of the target display to the target control mode. The at least one second display includes the target display; and a second transmission module 1430, which can be used to transmit media resources to the target controller based on the interface connection relationship between the first display and each of the at least one second display after the target controller sets the control mode of the target display to the target control mode, so that the target controller controls the target display to play the media resources based on the target control mode of the target display.

[0175] In some embodiments of the present invention, each of the first display and at least one second display includes a receiving interface and an output interface. The first transmission module 1420 can be used to output a control mode setting command through the output interface of the first display and access the next second display through the receiving interface of the next second display based on the interface connection relationship between the first display and at least one second display. The next second display is the second display that is directly connected to the first display among the at least one second display. The mode setting command is output through the output interface of the next second display through a second controller coupled to the next second display and accessed through the receiving interface of the next next second display, until the mode setting command is transmitted to the target controller.

[0176] In some embodiments of the present invention, each of the first display and at least one second display includes a receiving interface and an output interface. The second transmission module 1430 can be used to control media resources to be output through the output interface of the first display and connected to the next second display through the receiving interface of the next second display based on the interface connection relationship between the first display and at least one second display. The next second display is the second display that is directly connected to the first display among a plurality of second displays. The media resources are output through the output interface of the next second display through a second controller coupled to the next second display and connected to the next next second display through the receiving interface of the next next second display, until the media resources are transmitted to the target controller.

[0177] In some embodiments of the present invention, the mode setting instruction is also used to indicate the target control mode of the first display. The first transmission module 1420 can also be used to set the control mode of the first display to the individual control mode when the target control mode is the individual control mode and the target display indicated by the mode setting instruction is the first display; and to set the control mode of the first display to the unified control mode when the target control mode is the unified control mode.
