The operating system also allows the user to interact with the display device 200.

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

[0081] In order to facilitate the detailed description of the display control method provided by the embodiment of the present invention, Figure 3 A flow chart of a display control method provided by an embodiment of the present invention is shown. The method can be applied to Figure 1 A display device 200 is shown.

[0082] The display device 200 may be composed of a first display and at least one second display connected in sequence. For example, the first display and at least one second display may be spliced ​​to form a display device 200 with a larger size. 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 the at least one second display, and the second display is any one of the other displays in the display device 200 except the first display.

[0083] In this embodiment, the first controller is used to control the first display to display a picture or perform a corresponding operation, and the second controller is used to control the second display to display a picture or perform a corresponding operation. The second display corresponds to the second controller one by one.

[0084] The first display and the second display can both be used to display a user interface, which is an interactive interface between a user and the display device 200. The user can send instructions to the display device 200 through a remote control or touch control to control the display device to perform a certain task. The user interface has a perfect interactive design, which allows the user to easily complete a task. For example, the user interface can be a video playback interface, and the user can control the first display and any one or more second displays to display the video playback interface and play video data through a remote control or touch control.

[0085] In some embodiments, in the first display and the at least one second display, each display may include a receiving interface and an output interface. The first display and the at least one second display are connected in sequence, and in this case, on the connection path between the first display and the at least one second display, the output interface of the previous display may be connected to the receiving interface of the next 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 display may be used to receive audio and video signals from an external device, and send the audio and video signals to other devices, such as other displays connected to the display. When connecting, each display may be connected through an unused pin in the HDMI input interface and the HDMI output interface to achieve transmission of signals and data between the displays.

[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 interface and the HDMI output interface can reduce the connection interfaces between the various displays in the display device and facilitate the installation and maintenance of the display device.

[0088] In order 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. Figure 4 As shown, taking a 2*2 display device as an example, the display device consists of 4 displays, namely display 1, display 2, display 3 and display 4, and the 4 displays are distributed in a rectangular shape, each display includes a receiving interface and an output interface, and the output interface of the previous display is connected to the receiving interface of the next display, that is, a loop-out connection is realized between the displays through the interface, such as the output interface 1 of display 1 is connected to the receiving interface 2 of display 2, the output interface 2 of display 2 is connected to the receiving interface 3 of display 3, and the output interface 3 of display 3 is connected to the receiving interface 4 of display 4.

[0089] In some embodiments, 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 supply power to each display in the display device, in some embodiments, such as Figure 4 As shown, each display may include a power interface, and the power interface of each display may include a power input interface and a power output interface, such as display 1 includes power input interface 1 and power output interface 1, display 2 includes power input interface 2 and power output interface 2, etc.

[0091] The displays can be looped together through the power interface, that is, the power input interface 1 of display 1 is connected to the external power supply, the power output interface 1 is connected to the power input interface 2 of display 2, the power output interface 2 of display 2 is connected to the power input interface 3 of display 3, and the power output interface 3 of display 3 is connected to the power input interface 4 of display 4, so that power is supplied to each display through the power interface.

[0092] It should be understood that Figure 4 The number and arrangement of displays in the display device shown are only for illustration. According to actual display requirements, the display device can have any number of displays, and the arrangement layout of each display can also be set to any shape, which is not specifically limited in this embodiment.

[0093] In the connection path of multiple displays, the first display is the first display, and any display other than the first display is the second display. 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 by an embodiment of the present invention, the display device can receive a mode setting instruction through a first controller, and based on the interface connection relationship between the first display and each of the at least one second display, 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 the target control mode, that is, 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 each of the 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.

[0095] By applying this solution, a mode setting instruction can be received by a first controller coupled to a first display, and then based on the interface connection relationship between the first display and each of the at least one second display, the mode setting instruction is transmitted to a target controller coupled to a target display indicated by the mode setting instruction, thereby setting the target display to a target control mode, i.e., a separate control mode or a unified control mode, so that when a media resource is received, the target display can be controlled to play the media resource in accordance with the separate control mode or the unified control mode, thereby realizing separate control or unified control of multiple displays, and improving the control 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-S330:

[0097] Step S310: receiving a mode setting instruction.

[0098] Among them, the mode setting instruction can be used to indicate the target control mode of any one or more second displays in at least one second display, and the target control mode may include a separate control mode or a unified control mode. Specifically, the separate control mode refers to a mode for controlling the display or operation of a single display in the first display and at least one second display, and the unified control mode is a mode for controlling the display or operation of multiple displays in the first display and at least one second display. That is to say, when a display is in a separate control mode, the user can only operate the display without affecting the operation of other displays. When the display is in a unified control mode, the user can perform a one-time operation on all displays in the display device without having to operate each display one by one.

[0099] In this embodiment, in order 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 a mode setting instruction.

[0100] According to the way of controlling the display device, the user can send the mode setting instruction to the first controller in a variety of 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 second display in the mode setting interface to trigger the mode setting instruction of controlling the second display alone, or the user can also enter the number "0" in the mode setting interface to trigger the mode setting instruction of uniformly controlling all displays, that is, the first display and all second displays.

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

[0102] The command receiver may be a remote control signal receiver, a voice receiver, such as a microphone, etc. Taking the remote control signal receiver as an infrared remote control signal receiver as an example, Figure 5 FIG. 4 shows a schematic diagram of the structure of an infrared remote control signal receiver provided in this embodiment. Figure 5 As shown, the infrared remote control signal receiver 500 includes two ground pins (GND1 and GND4), one power pin (VCC), one signal output pin (OUT) and one standby voltage input pin (VS), wherein the signal output pin (OUT) is connected to the HDMI input interface of the first display, and can be used to output the received control signal of the remote control as a digital signal, and transmit it to the first controller of the first display for further processing.

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

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

[0105] In some embodiments, each of the first display and the at least one second display can be coupled to a corresponding command receiver. At this time, in order to achieve separate control of each display and avoid the first display and the at least one second display responding to the control signal of the remote control at the same time, the control code of the first display and each second display can be set. When controlling the first display or a second display, the user can set the control code of the remote control to the control code of the corresponding display, thereby using 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 each of the at least one second display, transmit the mode setting instruction to the 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 the target control mode.

[0107] The interface connection relationship between the first display and each of the at least one second display refers to the relationship between the data transmission interfaces of the first display and each of the at least one second display, such as the connection relationship between the receiving interface and the output interface of each display. For example, on the connection path between the first display and the at least one second display, between two adjacent displays, the output interface of the previous display can be connected to the receiving interface of the next display. The at least one second display may include a target display.

[0108] According to the interface connection relationship between the first display and each display in at least one second display, the transmission path of the signal or data between each display can be determined. Therefore, in order to realize the control of the second display, the first controller can execute step S321, that is, based on the interface connection relationship between the first display and each display in at least one second display, the mode setting instruction is synchronized to the target controller coupled to the target display indicated by the mode setting instruction. For example, when receiving the mode setting instruction, the first controller can parse the mode setting instruction, determine the second display indicated by the mode setting instruction, use it as the target display, and then transmit the mode setting instruction to the target controller coupled to the target display through the receiving interface and output interface of the corresponding display according to the interface connection relationship between the first display and each display in at least one second 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] In order to implement the processing and forwarding of the mode setting instruction, in some embodiments, reference Figure 6 As shown, when each of the first display and at least one second display receives a mode setting instruction, the mode setting instruction can be amplified and then transmitted to the controller of the display for processing. The mode setting instruction can also be transmitted to the output interface of the display for forwarding.

[0111] In some embodiments, each of the first display and the 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 method:

[0112] Step S710: Based on the interface connection relationship between the first display and each of the at least one second display, the control mode setting instruction 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 directly connected to the first display among the at least one second display.

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

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

[0116] For example, in Figure 4 When the display 2 in the example receives the mode setting instruction, the controller of the display 2 can control the display 2 to transmit the mode setting instruction to the next second display, that is, the display 3, through the output interface 2. The instruction transmission is performed in this way until the corresponding target display receives the mode setting instruction. Since the target display is coupled to the target controller, when the target display receives the mode setting instruction, the corresponding target controller will also receive the mode setting instruction.

[0117] Through the above method, the mode setting instruction can be transmitted to all corresponding target controllers based on the interface connection relationship between the first display and each display in at least one second display, so that the target controller can receive the mode setting instruction and set the control mode of the target display according to the mode setting instruction, thereby realizing the transmission of the mode setting instruction between multiple displays to perform mode control on 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 the separate control mode and the target display indicated by the mode setting instruction is the 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 the unified control mode.

[0119] Exemplarily, when the target display indicated by the mode setting instruction is the second display coupled to the second control, 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, when it is determined that the target control mode is a separate control mode and the current control mode is a separate control mode, keep the control mode of the second display coupled to the second controller as a separate control mode; when it is determined that the target control mode is a separate control mode and the current control mode is a unified control mode, switch the control mode of the second display coupled to the second controller to a separate control mode.

[0120] Correspondingly, when it is determined that the target control mode is 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 it is determined that the target control mode and the current control mode are both unified control modes, the control mode of the second display coupled to the second controller is maintained as the unified control mode.

[0121] In this way, the second controller can set the control mode of the second display coupled to it 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, i.e., the first display and all second displays. Therefore, the operational flexibility of the display device can be improved, and the display device can also provide a richer and more diverse screen display method.

[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 separate control mode when the target control mode is the separate 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] Exemplarily, 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, so that the user can operate and control only the first display, or operate and control the first display and all second displays, thereby also improving the operational flexibility of the display device and the diversity of screen display.

[0125] After setting the control mode of the first display to the individual control mode or the unified control mode, the user can set the first display. Figure 8 As shown, the first controller may also execute the following method:

[0126] Step S810: receiving a first display setting instruction.

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

[0128] Exemplarily, the user can control the first display to open a display setting interface through a touch operation, and then enter or select corresponding display parameters in the display setting interface, thereby triggering a first display setting instruction; or when the user enters an instruction to open the display setting interface through a remote control, the first controller can receive the control signal sent by the remote control through an infrared remote control signal receiver, thereby controlling the first display to display the display setting interface. In the display setting interface, the user can enter or select corresponding display parameters through the buttons of the remote control, thereby generating a first display setting instruction.

[0129] For another example, the user may also record a voice command through a microphone, such as a command to set a display parameter to a specified value, so that the first display switches to the display setting interface and generates a first display setting command according to the display parameter to be set.

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

[0131] When the first display is in the individual control mode or the 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. At this time, when the first display is in the individual control mode, only the display parameters of the first display will be updated, all the second displays are in the shielded state, and the display parameters remain unchanged. When the first display is in the unified control mode, the display parameters of the first display and all the second displays will be 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 mode of the first display and all the second displays, so that the first display can display the picture according to the display parameters set by the user, and in the separate control mode, it will not affect the picture display of the second display, thereby 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 the separate control mode or the unified control mode, the user can also set the second display. Fig. 9 As shown, the first controller may also execute the following method:

[0134] Step S910: receiving a second display setting instruction.

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

[0136] Correspondingly, the user can also control the second display to open the display setting interface through touch operation or voice operation, and then enter or select corresponding display parameters in the display setting interface to trigger the second display setting instruction, or the user can also control the first display to display the display setting interface through the remote control, and in the display setting interface, enter or select corresponding display parameters through the buttons of the remote control to generate the second display setting instruction.

[0137] Step S920: Based on the interface connection relationship between the first display and each of the at least one second display, transmit the second display setting instruction 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] Exemplarily, when the first controller receives the second display setting instruction, step S921 may be executed to transmit the second display setting instruction to the second controller according to the interface connection relationship between the first display and each of the at least one second display. Figure 4Taking the display device shown as an example, the first controller, that is, the controller corresponding to display 1 can, when receiving the second display setting instruction, transmit the second display setting instruction to the next second display, that is, 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 each of the at least one second display, and transmit the second display setting instruction to the next second display, that is, display 3, through the output interface 2 until all the second displays have received the second display setting instruction. Since the second displays are coupled to the second controller, when all the second displays receive the second display setting instruction, the corresponding second controllers will also receive the second display setting instruction.

[0139] When the second controller receives the second display setting instruction, the second controller may 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 may 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 included, the display parameters of the second display may be set to the target values ​​in the second display setting instruction.

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

[0141] Step S330: After the target controller sets the control mode of the target display to the target control mode, based on the interface connection relationship between the first display and each of the at least one second display, the media resources are transmitted to the target controller, 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] Among them, media resources are various forms of materials and content used for the purpose of disseminating information, expressing ideas, providing entertainment, etc., and can 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 and, when receiving the media resources, execute step S331 to synchronize the media resources to the target controller according to the interface connection relationship between the first display and each of the at least one second display, so that the target controller can 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 a separate 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 each play other media resources; when the target control mode of the target display is a 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 also control the target display to play local media resources according to the position of the target display in the first display and all second displays, thereby realizing the playback of one media resource on multiple displays.

[0145] In order to enable each second display to obtain media resources, in some embodiments, reference Fig.10 As shown, the first controller can execute the following method:

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

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

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

[0149] Step S1020: output the media resource through the output interface of the next second display via the second controller coupled to the next second display, and access the next next second display via the receiving interface of the next next second display until the media resource is transmitted to the target controller.

[0150] For example, when display 2 receives the media resource, the controller of display 2 can control display 2 to transmit the media resource to the next second display, i.e., display 3, through output interface 2. Instructions are transmitted in this way until the target controller coupled to the target display receives the media resource.

[0151] Through the above method, the 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 the media resources according to the corresponding control mode.

[0152] In some embodiments, after the control mode of the first display is set to the individual control mode, the first controller can also control the first display to play the media resource. At this time, when the first display plays the media resource, all second displays will not play the media resource. Thus, the display device can control the first display to play the media resource alone, so that a single display can play the media resource without affecting other displays playing other media resources.

[0153] In some embodiments, after the control mode of the first display is set to the unified control mode, referring to Fig.11 As shown, the first controller may also execute the following method:

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

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

[0156] According to the row and column position of the first display in the first display and at least one second display, the first screen area corresponding to the media resource can be determined when the media resource is played. For example, Figure 4 In the display device shown, since the display 1 is located at the 1st row and the 2nd column, the first screen area is the lower right corner area of ​​the media resource.

[0157] Exemplarily, 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 corresponding screen size of 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 play only the content in the first screen area, the first controller may perform screen capture processing on the media resource to obtain a first media resource including only the first screen area, thereby controlling the first display to play the first media resource.

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

[0161] In some embodiments, after the control mode of the second display coupled to the second controller is set to the individual control mode, the second controller can control the second display coupled to the second controller to play the media resource. At this time, when the second display plays the media resource, the first display and other second displays will not play the media resource. Thus, the display device can control the second display to play the media resource alone, so that the single display can play the media resource without affecting the other displays playing other media resources.

[0162] In some embodiments, after the control mode of the second display coupled to the second controller is set to the unified control mode, referring to Fig.12 As shown, the second controller can execute the following method:

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

[0164] 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 at the 2nd row and the 2nd column.

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

[0166] Step S1220: performing screen capture processing on the media resource according to the second screen area to obtain a second media resource, and controlling the second display coupled to the second controller to play the second media resource.

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

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

[0169] In order to prevent the external device from interfering with the remote control signal, in some embodiments, the first controller may also receive the media resource sent by the external device through the receiving interface of the first display.

[0170] The command receiver of the first display is connected to any idle pin of the HDMI input interface through a shielding circuit, and the shielding circuit is used to shield the interference of the peripheral device to the command receiver.

[0171] In some embodiments, the shielding circuit may be provided with a switch to control whether the function of the shielding circuit is enabled. Fig.13 FIG. 4 shows a connection diagram of a shielding circuit provided by an embodiment of the present invention. Fig.13 As shown, the shielding circuit is connected to the power supply. When the power supply is turned on, the shielding circuit takes effect, which can make the control signal pin of the first display in a suspended state, disconnect the connection with the external device, and solve the interference of the external device 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, and then based on the interface connection relationship between the first display and each of the at least one second display, the mode setting instruction is transmitted to a target controller coupled to a 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, so that when a media resource is received, the target display can be controlled to play the media resource in a separate control mode or a unified control mode, thereby realizing separate control or unified control of multiple displays, and improving the control flexibility of the display device and the diversity of the displayed screen.

[0173] In some implementations of this embodiment, a shielding circuit can be provided to solve the signal interference generated by the peripheral device to the command receiver of the first display when the peripheral device inputs media resources, thereby improving the control quality of the display device.

[0174] The embodiment of the present invention further provides a display control device, referring to Fig.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, 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 the at least one second display, and 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 of any one or more second displays in at least one second display, and 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 a 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 display in the at least one second display, so that the target controller sets the control mode of the target display to the target control mode, and 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 display in 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.
