[0052] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. In the description of the embodiments of the present application, the terms used in the following embodiments are only for the purpose of describing the specific embodiments and are not intended to be limiting on the present application. As used in the specification and the appended claims of the present application, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. It will also be understood that “at least one” and “one or more” as used in the embodiments herein indicates one or two or more (including two), unless otherwise indicated. The term “and / or” is used to describe the association relationship of the associated objects, which means that there can be three relationships; for example, A and / or B can mean that A exists alone, A and B exist together, and B exists alone, where A and B can be singular or plural. The character “ / ” generally represents an “or” relationship between the associated objects.

[0053] In this specification, the reference “one embodiment” or “some embodiments” means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the present application. Thus, the appearances of the phrases “in one embodiment”, “in some embodiments”, “in other embodiments”, “in additional embodiments”, etc. in various places in this specification are not necessarily all referring to the same embodiment, but can refer to one or more but not all embodiments, unless otherwise indicated. The terms “comprising”, “including”, “having” and their variants mean “including but not limited to”, unless otherwise indicated. The term “connected” includes both direct connection and indirect connection, unless otherwise indicated. “First”, “second”, etc. are used only for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0054] In the embodiments of the present application, the words “exemplary” or “for example” are used to mean serving as an example, instance, or illustration. Any embodiment or design presented as “exemplary” or “for example” in the embodiments of the present application is not necessarily to be construed as preferred or advantageous over other embodiments or design solutions. Rather, the use of the words “exemplary” or “for example” is intended to present concepts in a concrete manner.

[0055] Generally, the electronic device with a larger display screen size can bring better visual impact and better user experience to users than the electronic device with a smaller display screen size. However, the electronic device with a larger display screen size is limited in manufacturing technology and has a significantly increased cost. In some occasions such as stage performance or home viewing, multiple electronic devices with smaller display screen sizes can be connected by wires and a split screen device to achieve a combined display, so that the audience far away can also enjoy a better display effect or the same display effect as the electronic device with a larger display screen size. However, this requires complex wiring and a dedicated split screen device (such as a splitter) to control the combination and image display of different display screens of different electronic devices, thereby increasing the hardware cost. Therefore, how to achieve the combined display of multiple different electronic devices with smaller display screen sizes while reducing the hardware cost becomes a technical problem to be solved.

[0056] To solve the above technical problem, the application provides a combined display method, a mobile device, an electronic device and a combined display system.

When receiving a first input, the mobile device 100 can send a broadcast message to the multiple electronic devices, the broadcast message being used to instruct the multiple electronic devices in the local area network to enter a combined display state. After receiving the broadcast message, the multiple electronic devices can display information indicating their addresses on their respective display screens. The mobile device 100 can determine the position information of each electronic device in the multiple electronic devices and the address information of each electronic device through the first image information. The mobile device 100 can send indication information to one of the multiple electronic devices (for example, the electronic device 200), the indication information being used to indicate the position information of each electronic device in the multiple electronic devices and the address information of each electronic device. The electronic device 200 receiving the indication information can split the image information to be displayed according to the indication information, so as to display part of the image information on the display screen of the electronic device 200 and send the other part of the image information to the remaining electronic devices.

[0086] The following takes the electronic devices 200-203 included in a local area network as an example, and combines the combination display method provided in the embodiments of the present application with the communication between the electronic devices. Figures 4 to 7 The combination display method provided in the embodiments of the present application is shown in the schematic flowchart. Figure 4 As shown in the schematic flowchart, the combination display method includes: Figure 4

[0087] ​​S401, in response to receiving the first input, the mobile device 100 sends a broadcast message, the broadcast message being used to instruct the electronic devices in the local area network to enter a combined display state.

[0088] In one embodiment, the electronic devices 200-203 can be in a discovery-ready state.

[0089] For example, when the mobile device needs to perform screen projection, the mobile device can search for the electronic devices in the local area network that are in the discovery-ready state, thereby prompting the user to perform screen projection on the electronic devices 200-203. For example, Figure 9 As shown in (a) of FIG. 10, the mobile phone, the smart TV 1, the smart TV 2, the smart TV 3, and the smart TV 4 are in the same local area network, and the mobile phone displays a video playing interface including a video display window 901 and a screen projection control 902. The smart TV 1, the smart TV 2, the smart TV 3, and the smart TV 4 are in the discovery-ready state. In response to detecting that the user clicks the control 902, the mobile phone can display a GUI as shown in (b) of FIG. 10. Figure 9 As shown in the GUI of (b) of FIG. 10, the mobile phone can display a prompt box 903, where the prompt box 903 includes device information of the smart TV 1, the smart TV 2, the smart TV 3, and the smart TV 4 in the local area network that are in the discovery-ready state. Figure 9 As shown in the GUI of (b) of FIG. 10, the mobile phone can display a prompt box 903, where the prompt box 903 includes device information of the smart TV 1, the smart TV 2, the smart TV 3, and the smart TV 4 in the local area network that are in the discovery-ready state.

[0090] In one embodiment, the electronic devices 200-203 can enter the discovery-ready state when detecting a user's power-on operation.

[0091] In one embodiment, the electronic devices 200-203 can also be in the discovery-ready state within a preset time length (for example, 10 minutes) from detecting a user's power-on operation.

[0092] In one embodiment, when the mobile device detects a first operation of the user, the mobile device sends the broadcast message to the devices in the local area network.

[0093] For example, as shown in (b) of FIG. 10, when the mobile phone detects that the user clicks the control 1002, the mobile phone can send the broadcast message to the devices in the local area network. Figure 10 For example, as shown in (a) of FIG. 11, when the mobile phone detects that the user clicks the control 1102, the mobile phone can send the broadcast message to the devices in the local area network.

[0094] Figure 11 For example, as shown in (a) of FIG. 11, when the mobile phone detects that the user clicks the control 1102, the mobile phone can send the broadcast message to the devices in the local area network.

[0095] ​It should be understood that in the embodiments of the present application, the broadcast message is used to instruct the electronic devices in the local area network to enter the combined display state, i.e., instruct the electronic devices in the local area network to perform combined display; it can also be understood that the display screens of the plurality of electronic devices in the local area network form a larger display screen.

[0096] For example, the broadcast message can be a user datagram protocol (UDP) data packet. The UDP data packet includes a data part of an IP datagram. The data part of the IP datagram can include an extensible bit. The electronic devices 200-203 and the mobile device 100 can agree on the content of the extensible bit. When the extensible bit is 1, the electronic devices 200-203 can learn that the mobile device 100 wants them to enter the combined display state.

[0097] In one embodiment, the devices supporting combined display (e.g., the electronic devices 200-203) and the devices not supporting combined display (e.g., tablets, smart watches, sound boxes) can access the same local area network. The devices supporting combined display can respond to the broadcast message sent by the mobile device 100 (e.g., display address information on the display screen) after receiving the broadcast message, and the devices not supporting combined display can ignore the broadcast message after receiving the broadcast message.

[0098] S402, in response to receiving the broadcast message, the electronic device 200 displays first information on the display screen, and the first information is used to indicate the address of the electronic device 200.

[0099] S403, in response to receiving the broadcast message, the electronic device 201 displays second information on the display screen, and the second information is used to indicate the address of the electronic device 201.

[0100] S404, in response to receiving the broadcast message, the electronic device 202 displays third information on the display screen, and the third information is used to indicate the address of the electronic device 202.

[0101] S405, in response to receiving the broadcast message, the electronic device 203 displays fourth information on the display screen, and the fourth information is used to indicate the address of the electronic device 203.

[0102] It should be understood that there is no actual sequence between S402-S405.

[0103] For example, the electronic devices 200-203 are smart TV 1, smart TV 2, smart TV 3, and smart TV 4. Figure 10As shown in (b) of FIG. 1, when the smart TV 1, the smart TV 2, the smart TV 3 and the smart TV 4 receive the broadcast message, the smart TVs can display the two-dimensional code on the display screen respectively, and the two-dimensional code is used to indicate the MAC address.

[0104] It should be understood that the above-mentioned way of displaying the two-dimensional code on each smart TV to indicate the MAC address of the smart TV is only illustrative, and the embodiments of the present application are not limited thereto. For example, after receiving the broadcast message, each smart TV can also display the MAC address of the smart TV on the display screen. For example, after receiving the broadcast message, the smart TV 1 can display "3E-57-48-00-F8-ED" on the display screen.

[0105] S406, the mobile device acquires first image information in response to the received second input, and the first image information includes the display screen of the electronic device 200, the display screen of the electronic device 201, the display screen of the electronic device 202 and the display screen of the electronic device 203.

[0106] In one embodiment, the first image information includes the display screen of the electronic device 200, and the display screen of the electronic device 200 displays first information; the first image information includes the display screen of the electronic device 201, and the display screen of the electronic device 201 displays second information; the first image information includes the display screen of the electronic device 202, and the display screen of the electronic device 202 displays third information; and the first image information includes the display screen of the electronic device 203, and the display screen of the electronic device 203 displays fourth information.

[0107] In one embodiment, the mobile device acquires the first image information when detecting that the user performs the operation of photographing the electronic device 200 to the electronic device 203.

[0108] For example, as shown in (d) of FIG. 1, when the mobile phone detects that the user clicks the control 1006, the mobile phone can acquire the image information in the preview frame, and the image information includes the two-dimensional code information displayed on the smart TV 1, the smart TV 2, the smart TV 3 and the smart TV 4. Figure 10

[0109] It should be understood that the first image information can include one frame or multiple frames of image. The mobile device can prompt the user to take a photo of the electronic device to be combined and displayed, so as to obtain one frame of image information, or the mobile device can also prompt the user to record a video of the electronic device to be combined and displayed, so as to obtain multiple frames of image information.

[0110] In one embodiment, the mobile device acquires the first image information when detecting that the image of the electronic device (such as the electronic device 200 to the electronic device 203) is located in the preview frame for a preset time length, and no image of other electronic device is supplemented into the preview frame. ​

[0111] In one embodiment, before the mobile device detects the second input of the user, the mobile device may further prompt the user to obtain image information including multiple electronic devices that need to be displayed in combination.

[0112] In one embodiment, electronic devices 200-203 may also send a response to the mobile device in response to receiving the broadcast message. If the mobile device receives responses from multiple electronic devices, the mobile device may prompt the user that multiple electronic devices have been discovered within the local area network and prompt the user whether to combine and display the multiple electronic devices. In response to the user determining to combine and display multiple electronic screen devices within the local area network, the mobile device may prompt the user to obtain image information including the multiple electronic devices to be combined and displayed.

[0113] S407: The mobile device determines the position information and address information of each electronic device among the multiple electronic devices based on the first image information.

[0114] In an embodiment of the present application, the mobile device can determine the address information of the electronic device 200-electronic device 203 through the first information to the fourth information displayed on the display screen of the electronic device 200-electronic device 203, and can determine the orientation information of the electronic device 200-electronic device 203 through the position of the electronic device 200-electronic device 203 in the first image information.

[0115] For example, Figure 10 As shown in (d), the mobile phone can determine that the address information of the device on the upper left (smart TV 1) is MAC address 1, the address information of the device on the upper right (smart TV 2) is MAC address 2, the address information of the device on the lower left (smart TV 3) is MAC address 3, and the address information of the device on the lower right (smart TV 4) is MAC address 4.

[0116] S408: The mobile device sends indication information to the electronic device 200. The indication information is used to indicate the position information of each electronic device and the address information of each electronic device in the plurality of electronic devices.

[0117] In one embodiment, the indication information may include the first information, the second information, the third information, the fourth information, the orientation information between the display screen of the electronic device 200 and the display screen of the electronic device 203, the correspondence between the first information and the display screen of the electronic device 200, the correspondence between the second information and the display screen of the electronic device 201, the correspondence between the third information and the display screen of the electronic device 202, and the correspondence between the fourth information and the display screen of the electronic device 203.

[0118] In one embodiment, if the devices that need to be combined for display include the electronic device 200 and the electronic device 201, the indication information can include the first information, the second information, the orientation information of the display screen of the electronic device 200 and the display screen of the electronic device 201, and the correspondence between the first information and the display screen of the electronic device 200.

[0119] In one embodiment, the mobile device can further send another indication information to the electronic device 200, where the another indication information is used to indicate that the electronic device 200 is the master device.

[0120] In one embodiment, the indication information and the another indication information can be carried in the same message or in different messages.

[0121] For example, the mobile device can carry the matrix information in the indication information, where the matrix information is used to indicate the orientation information of each electronic device in the plurality of electronic devices and the address information of each electronic device.

[0122] For example, the matrix information M carried in the indication information can be as shown in the formula (1):

[0123]

[0124] Upon receiving the indication information, the electronic device 200 can obtain the matrix M, where the MAC address 1 shown in the first row and the first column of the matrix M can represent that the MAC address of the electronic device at the top left is the MAC address 1, the MAC address 2 shown in the first row and the second column of the matrix M can represent that the MAC address of the electronic device at the top right is the MAC address 2, the MAC address 3 shown in the second row and the first column of the matrix M can represent that the MAC address of the electronic device at the bottom left is the MAC address 3, and the MAC address 4 shown in the second row and the second column of the matrix M can represent that the MAC address of the electronic device at the bottom right is the MAC address 4. Since the MAC address of the electronic device 200 is the MAC address 1, the electronic device 200 can determine that it is located at the top left of the plurality of electronic devices, and the electronic device 200 can also determine the orientation information of the other electronic devices and the MAC addresses thereof.

[0125] In one embodiment, when the mobile device determines that there are a plurality of electronic devices that need to be combined for display, the mobile device can select an electronic device (e.g., the electronic device 200) at random and send the indication information to the electronic device.

[0126] In one embodiment, in response to receiving the indication information, the electronic device 200 can prompt a user through the display screen that the electronic device 200 can control the electronic devices 200-203 to display image information.

[0127] In one embodiment, before the mobile device sends the instruction information to the electronic device 200 , it may first determine whether the distribution of the multiple electronic devices in the first image information is regular.

[0128] For example, Figure 12 As shown in (b) of FIG, when the mobile phone detects that the user clicks control 1202, the mobile phone can obtain the first image information in the preview frame. The mobile phone can determine the position and address information of Smart TVs 1-5 based on the first image information. For example, the mobile phone can determine from the first image information that the MAC address of the electronic device located at the upper left is MAC address 5; the MAC address of the electronic device located at the upper center is MAC address 1; the MAC address of the electronic device located at the lower center is MAC address 3; the MAC address of the electronic device located at the upper right is MAC address 2; and the MAC address of the electronic device located at the lower right is MAC address 4.

[0129] The mobile phone can convert the position information and address information of smart TV 1 to smart TV 5 into a matrix N. The matrix information N can be shown as formula (2):

[0130]

[0131] The mobile phone can determine that the matrix N is an irregular matrix, and thus the mobile phone can determine that the distribution of smart TVs 1 to 5 is irregular.

[0132] In one embodiment, if the mobile device determines that the multiple electronic devices are irregularly distributed, the electronic device may prompt the user to select some electronic devices from the multiple electronic devices for combined display.

[0133] For example, Figure 12 As shown in (c) of FIG, if the mobile phone determines that Smart TVs 1-5 are irregularly distributed, it can select Smart TVs 1-4, which are regularly distributed, for combined display. The mobile phone can prompt the user, "We have detected that five electronic devices need to be combined for display. To ensure image display quality, we recommend that you select the devices in the dashed box for combined display." In step S409, electronic device 200 controls electronic devices 200-203 to display images based on this instruction.

[0134] It should be understood that the process of S409 can refer to Figures 7-8 The process shown will not be repeated here.

[0135] In one embodiment, the mobile device can also not send the indication information to the electronic device, but send the first image to the electronic device 200. After receiving the first image, the electronic device 200 can determine the first information, the second information, the third information, the fourth information, the orientation information between the display screen of the electronic device 200 and the display screen of the electronic device 203, the corresponding relationship between the first information and the display screen of the electronic device 200, the corresponding relationship between the second information and the display screen of the electronic device 201, the corresponding relationship between the third information and the display screen of the electronic device 202, and the corresponding relationship between the fourth information and the display screen of the electronic device 203 according to the first image. After determining the above information, the electronic device 200 can segment the image frame, and then control the electronic device 200 to the electronic device 203 to display the image.

[0136] The above Figure 4 In S408 shown above, the mobile device can be to select an electronic device (for example, the electronic device 200) from the plurality of electronic devices and send the indication information to the electronic device, or the mobile device can be to send the indication information to the electronic device 200 when detecting that the user selects the electronic device 200 from the plurality of electronic devices. Figure 5 Another schematic flow of the combined display method provided by the embodiments of the present application is shown. As shown in Figure 5 The method includes:

[0137] S4081, in response to determining the orientation information of each electronic device in the plurality of electronic devices and the address information of each electronic device, the mobile device prompts the user to select an electronic device (for example, the electronic device 200) from the plurality of electronic devices as the master device.

[0138] It should be understood that in the embodiments of the present application, after the plurality of electronic devices are combined to display, the master device can be discovered by the devices (for example, the devices that need to be projected) in the local area network, and the master device can be used to segment the image information that needs to be displayed, and control the plurality of electronic devices to display the segmented image information respectively.

[0139] For example, as shown in (e) of Figure 10 When the mobile phone detects that the user selects the electronic device with the MAC address of MAC address 1 and clicks the control 1008, the mobile phone can determine that the electronic device with the MAC address of MAC address 1 is the master device.

[0140] S4082, the mobile device sends the indication information to the electronic device 200 in response to the operation of the user selecting the electronic device 200 as the master device.

[0141] It should be understood that the process of the mobile device sending the indication information to the electronic device 200 can refer to the description of S408 above, which will not be described here.

[0142] In the embodiments of the present application, after receiving the indication information sent by the mobile device, the electronic device 200 can also notify the electronic devices 201-203 to close the device discovery state. Figure 6 Another exemplary flow of the combined display method provided by the embodiments of the present application is shown. As shown in Figure 6 The method comprises:

[0143] S4083, in response to receiving the indication information sent by the mobile device, the electronic device 200 notifies the electronic device 201 to close the device discovery.

[0144] In one embodiment, the electronic device 200 notifying the electronic device 201 to close the device discovery comprises: the electronic device 200 sending a notification message to the electronic device 201, the notification message being used to instruct the electronic device 201 to stop being in the discovery state.

[0145] S4084, the electronic device 201 closes the device discovery.

[0146] S4085, in response to receiving the indication information sent by the mobile device, the electronic device 200 notifies the electronic device 202 to close the device discovery.

[0147] In one embodiment, the electronic device 200 notifying the electronic device 202 to close the device discovery comprises: the electronic device 200 sending a notification message to the electronic device 202, the notification message being used to instruct the electronic device 202 to stop being in the discovery state.

[0148] S4086, the electronic device 202 closes the device discovery.

[0149] S4087, in response to receiving the indication information sent by the mobile device, the electronic device 200 notifies the electronic device 203 to close the device discovery.

[0150] In one embodiment, the electronic device 200 notifying the electronic device 203 to close the device discovery comprises: the electronic device 200 sending a notification message to the electronic device 203, the notification message being used to instruct the electronic device 203 to stop being in the discovery state.

[0151] S4088, the electronic device 203 closes the device discovery.

[0152] It should be understood that, in the embodiments of the present application, the electronic device 200 notifying the electronic devices 201-203 to close the device discovery can also be understood as the electronic device 200 notifying the electronic devices 201-203 to stop being in the discovery state.

[0153] It should also be understood that in an embodiment of the present application, after electronic device 201-electronic device 203 turns off device discovery, other devices in the local area network (for example, mobile devices) will not search for electronic device 201-electronic device 203 when searching for devices in the local area network that can cast screens.

[0154] It should also be understood that there is no actual sequence between S4083-S4084, S4085-S4086 and S4087-S4088.

[0155] For example, Figure 10 As shown in (e) in FIG, when the mobile phone detects that the user selects the electronic device (smart TV 1) with the MAC address of MAC address 1 and clicks the control 1008, the mobile phone can send the instruction information to smart TV 1. After receiving the instruction information, smart TV 1 can notify smart TV 2, smart TV 3 and smart TV 4 to turn off device discovery. Figure 10 As shown in (g), the only device that can be cast screen in the local area network searched by the mobile phone is smart TV 1.

[0156] The following combination Figure 7 and Figure 8 , a detailed description is given of the electronic device 200 controlling the electronic devices 200 to 203 to display images according to the instruction information in the above S409. Figure 7 FIG. 2 shows another schematic flow chart of the combined display method provided in an embodiment of the present application. Figure 7 As shown, the method includes:

[0157] S4091, in response to receiving the third input, the mobile device discovers an electronic device 200 in the local area network that can perform screen projection.

[0158] For example, Figure 10 As shown in (g), the mobile phone can prompt the user to select a screen projection device and display a list of searched devices, which includes smart TV 1.

[0159] It should be understood that the mobile device in S4091 can be used with the above Figures 4-6 The mobile devices in the embodiment of the present application may be the same device or different devices, which is not limited to this.

[0160] S4092, in response to the user selecting the electronic device 200 for screen projection, the mobile device may send image information to be displayed to the electronic device 200.

[0161] For example, Figure 10 As shown in (g), when the mobile phone detects that the user selects the operation of the smart TV 1, the mobile phone can send image information of the video display window 1009 to the smart TV 1.

[0162] S4093, in response to receiving the image information, the electronic device 200 segments the image information according to the indication information.

[0163] In one embodiment, the electronic device 200 segments the image information according to the indication information to obtain first, second, third and fourth partial image information.

[0164] In one embodiment, the electronic device 200 segments the image information according to the indication information, including: the electronic device 200 segments the image information according to the orientation information of the display screen of the electronic device 200, the display screen of the electronic device 201, the display screen of the electronic device 202 and the display screen of the electronic device 203.

[0165] In one embodiment, the electronic device 200 segments the image information according to the indication information, including: the electronic device 200 segments the image information according to the orientation information of the display screen of the electronic device 200, the display screen of the electronic device 201, the display screen of the electronic device 202 and the display screen of the electronic device 203.

[0168] S4095, the electronic device 200 sends the second partial image information to the electronic device 201 and instructs to display the second partial image information on the display screen of the electronic device 201, sends the third partial image information to the electronic device 202 and instructs to display the third partial image information on the display screen of the electronic device 202, and sends the fourth partial image information to the electronic device 203 and instructs to display the fourth partial image information on the display screen of the electronic device 203 according to the indication information.

[0169] In one embodiment, the electronic device 200 determines to send the second partial image information to the electronic device 201 according to the orientation information of the electronic device 201; the electronic device 200 determines to send the third partial image information to the electronic device 202 according to the orientation information of the electronic device 202; the electronic device 200 determines to send the fourth partial image information to the electronic device 203 according to the orientation information of the electronic device 203.

[0170] For example, when the electronic device 200 obtains the image information sent by the mobile device, the electronic device 200 can split the image information according to the number and the position information of the electronic devices in the matrix M. For example, the matrix M includes MAC addresses 1-4, which indicates that four electronic devices are combined to display, and the four electronic devices are located at the upper left, the upper right, the lower left and the lower right, respectively. Then, the electronic device 200 can split one frame of image information sent by the mobile device into four frames of image information according to the positions of the four electronic devices. Thus, the electronic device 200 can display the image information at the upper left; the electronic device 200 can send the image information at the upper right to the electronic device corresponding to the MAC address 2 in the first row and the second column of the matrix M, so that the electronic device displays the image information at the upper right; the electronic device 200 can send the image information at the lower left to the electronic device corresponding to the MAC address 3 in the second row and the first column of the matrix M, so that the electronic device displays the image information at the lower left; and the electronic device 200 can send the image information at the lower right to the electronic device corresponding to the MAC address 4 in the second row and the second column of the matrix M, so that the electronic device displays the image information at the lower right.

[0171] It should be understood that there is no actual sequence between S4094 and S4095.

[0172] For example, as shown in (h) of FIG. 10, when the smart TV 1 receives the image information sent by the mobile phone, the smart TV 1 can split the image information into image information 1012, image information 1013, image information 1014 and image information 1015. The smart TV 1 can display the image information 1012 at the upper left; the smart TV 1 can also send the image information 1013 to the smart TV 2, so that the smart TV 2 displays the image information 1013 at the upper right; the smart TV 1 can also send the image information 1014 to the smart TV 3, so that the smart TV 3 displays the image information 1014 at the lower left; and the smart TV 1 can also send the image information 1015 to the smart TV 4, so that the smart TV 4 displays the image information 1015 at the lower right. Figure 10

[0173] Another exemplary flow of the combination display method provided by the embodiments of the present application is shown. As shown in FIG. 11, the method includes the following steps. Figure 8 Figure 8

[0174] S4096, the electronic device 200 splits the local content or the live content into image information in response to detecting that the user operates the electronic device 200 to play the local content or the live content.

[0175] In one embodiment, the electronic device 200 splits the image information into first part image information, second part image information, third part image information and fourth part image information according to the indication information.​​

[0176] S4097, the electronic device 200 displays the first part of image information according to the indication information.

[0177] In one embodiment, the electronic device 200 displays the first part of image information according to the orientation information of the electronic device 200.

[0178] S4098, the electronic device 200 sends the second part of image information to the electronic device 201 and instructs to display the second part of image information on the display screen of the electronic device 201, sends the third part of image information to the electronic device 202 and instructs to display the third part of image information on the display screen of the electronic device 202, and sends the fourth part of image information to the electronic device 203 and instructs to display the fourth part of image information on the display screen of the electronic device 203 according to the indication information.

[0179] In one embodiment, the electronic device 200 determines to send the second part of image information to the electronic device 201 according to the orientation information of the electronic device 201, determines to send the third part of image information to the electronic device 202 according to the orientation information of the electronic device 202, and determines to send the fourth part of image information to the electronic device 203 according to the orientation information of the electronic device 203.

[0180] It should be understood that the difference between S4096 and S4093 is that in S4093, the electronic device 200 needs to receive the image information sent by the mobile device and control the electronic devices 200-203 to display images; while in S4096, the electronic device 200 does not need to receive the image information sent by other devices in the local area network, and the electronic device 200 controls the electronic devices 200-203 to display images when playing local content or live content.

[0181] It should also be understood that S4091-S4095 and S4096-S4098 are in a parallel relationship.

[0182] It should also be understood that the process of the electronic device 200 controlling the electronic devices 200-203 to display images in S4096-S4098 can refer to the process of S4093-S4095 described above, and for the sake of brevity, will not be repeated here.

[0183] For example, as Figure 13As shown, when the smart TV 1 detects that the user has switched to the channel display interface via the remote control, the image information corresponding to the channel display interface may be divided into image information 1301, image information 1302, image information 1303, and image information 1304. The smart TV 1 may display the image information 1301 in the upper left corner; the smart TV 1 may also send the image information 1302 to the smart TV 2, so that the smart TV 2 displays the image information 1302 in the upper right corner; the smart TV 1 may also send the image information 1303 to the smart TV 3, so that the smart TV 3 displays the image information 1303 in the upper right corner; and the smart TV 1 may also send the image information 1304 to the smart TV 4, so that the smart TV 4 displays the image information 1304 in the upper right corner.

[0184] The technical solution provided by this application does not require a dedicated split-screen device; in addition, through wireless means, there is no need for complex wiring between different electronic devices; since split-screen devices and wiring between different electronic devices are no longer used, costs are also reduced; and a combined display of multiple different electronic devices is achieved.

[0185] The following combination Figures 9 to 14 The graphical user interface (GUI) shown further illustrates the combined display method of the embodiment of the present application. Figure 9 A set of GUIs provided by an embodiment of the present application is shown.

[0186] like Figure 9 As shown in (a) of FIG, a mobile phone, smart TV 1, smart TV 2, smart TV 3 and smart TV 4 are located in the same local area network. The mobile phone displays a video playback interface, which includes a video display window 901 and a screen projection control 902. Smart TV 1, smart TV 2, smart TV 3 and smart TV 4 are in a waiting state. In response to detecting that a user clicks on control 902, the mobile phone can display the following: Figure 9 The GUI shown in (b) in FIG.

[0187] like Figure 9 In the GUI shown in (b), the mobile phone can display a prompt box 903, wherein the prompt box 903 includes device information of smart TV 1, smart TV 2, smart TV 3 and smart TV 4 in a to-be-discovered state in the local area network.

[0188] For example, when the mobile phone detects that the user selects an operation of the smart TV 2 , the mobile phone may send the image information in the video display window 901 to the smart TV 2 .

[0189] Figure 10 This is another set of GUIs provided in an embodiment of the present application.

[0190] like Figure 10 As shown in (a) of FIG, the living room includes smart TV 1, smart TV 2, smart TV 3 and smart TV 4. The mobile phone displays the mobile phone desktop. The mobile phone desktop includes icons of multiple applications, including clock, calendar, gallery, memo and smart life. In response to detecting input (such as click, etc.) for an APP (such as smart life) icon, the mobile phone can display the following Figure 10 The GUI shown in (b) in FIG.

[0191] In the embodiment of the present application, the mobile phone, smart TV 1, smart TV 2, smart TV 3 and smart TV 4 can be connected to the same router. Alternatively, there is a central device, such as a mobile phone, between the mobile phone, smart TV 1, smart TV 2, smart TV 3 and smart TV 4.

[0192] For example, a router can be used as an access point (AP) to provide a signal source for the network. Furthermore, a mobile phone, smart TV 1, smart TV 2, smart TV 3, and smart TV 4 can access the router as a station (STA). The router can communicate with each electronic device separately through a wired network or a wireless network. Exemplarily, a Wi-Fi link is established between each electronic device through a wireless fidelity (Wi-Fi) protocol to enable communication between devices. A specific implementation can be to establish a peer-to-peer (P2P) connection (or Wi-Fi Direct) between each electronic device, or to access the same router to enable communication between devices.

[0193] For example, a Wi-Fi P2P GO, or Group Owner, is created on a central device (e.g., a mobile phone). Other devices connect to this GO as P2P GCs, or Group Clients. These devices then form a one-to-many combination display and can communicate with each other.

[0194] In one embodiment, when Smart TV 1, Smart TV 2, Smart TV 3, and Smart TV 4 are powered on, they can be in a waiting-to-be-discovered state for a preset period of time (e.g., 10 minutes) from the time of power-on, and other devices in the local area network can discover Smart TV 1, Smart TV 2, Smart TV 3, and Smart TV 4. For example, when a mobile phone needs to cast a screen, the mobile phone can search for devices in the local area network, thereby prompting the user to cast the screen on Smart TV 1, Smart TV 2, Smart TV 3, or Smart TV 4.

[0195] like Figure 10As shown in (b) of FIG, the mobile phone can display the display interface of smart life. In response to detecting the user clicking the control 1001, the mobile phone can display a function list, wherein the function list includes functions such as discovering devices, creating smart devices, sharing devices, and connecting to third-party platforms.

[0196] In one embodiment, in response to detecting that a user clicks on the device discovery function 1002, the mobile phone may send a broadcast message to a device in the same local area network as the mobile phone, and the broadcast message is used to instruct the electronic device to enter a combined display state. In response to receiving the broadcast message, smart TV 1, smart TV 2, smart TV 3, and smart TV 4 may display a QR code through the display screen. The QR code displayed by each smart TV is used to indicate its address information (e.g., a media access control (MAC) address). Exemplarily, the QR code information displayed by smart TV 1 indicates that the address information of smart TV 1 is MAC address 1, the QR code information displayed by smart TV 2 indicates that the address information of smart TV 2 is MAC address 2, the QR code information displayed by smart TV 3 indicates that the address information of smart TV 3 is MAC address 3, and the QR code information displayed by smart TV 4 indicates that the address information of smart TV 4 is MAC address 4.

[0197] like Figure 10 As shown in (c) of FIG, the mobile phone can display another display interface of smart life. The display interface includes a prompt box 1003, wherein the prompt box 1003 includes a prompt message "It is detected that there are multiple electronic devices in the local area network. Do you want to display multiple electronic devices in combination?" In response to the mobile phone detecting that the user clicks the control 1004, the mobile phone can display the following Figure 10 The GUI shown in (d) in FIG.

[0198] In one embodiment, after the mobile phone sends a broadcast message, smart TV 1, smart TV 2, smart TV 3 and smart TV 4 can send a response to the mobile phone. If the mobile phone receives multiple electronic devices (for example, smart TV 1, smart TV 2, smart TV 3 and smart TV 4), the mobile phone can display the prompt box 1003.

[0199] like Figure 10 As shown in (d) in the figure, the mobile phone can start the camera and display a prompt message "Please place the electronic devices that need to be displayed in combination in the preview box below". The mobile phone can display the information of multiple devices collected by the mobile phone camera in the preview box 1005. When the mobile phone detects that the user clicks the control 1006, the mobile phone can display the following Figure 10 The GUI shown in (e) in FIG.

[0200] In one embodiment, when the mobile phone detects that the user clicks control 1006, the mobile phone can determine the address information of the multiple smart TVs based on the QR code information displayed on the multiple smart TVs in the preview box 1005. At the same time, the mobile phone can also determine the orientation information of each smart TV based on the image information in the preview box 1005. For example, the mobile phone can determine that the device with MAC address 1 is located in the upper left, the device with MAC address 2 is located in the upper right, the device with MAC address 3 is located in the lower left, and the device with MAC address 4 is located in the lower right.

[0201] like Figure 10 As shown in (e) of FIG, the mobile phone may display a prompt message "Detected that there are currently 4 electronic devices that need to be combined for display. Please select one electronic device as the master device." In response to the mobile phone detecting that the user selects device 1007 in the upper left corner and detects that the user clicks control 1008, the mobile phone may determine that the device with address information of MAC address 1 is the master device.

[0202] In one embodiment, when the mobile phone determines that the user selects smart TV 1 as the main control device, the mobile phone can send an indication message to smart TV 1, which is used to indicate the address information of other smart TVs (smart TV 2, smart TV 3 and smart TV 4) and the location information between other smart devices and smart TV 1.

[0203] In an embodiment of the present application, the instruction information sent by the mobile phone to the smart TV 1 can be used for image segmentation of the smart TV 1. After obtaining the instruction information, the smart TV 1 can determine which devices the user has combined for display and which device the segmented image should be sent to for display. For example, the smart TV 1 can know from the instruction information that the user has combined and displayed four devices and that the smart TV 1 is located in the upper left of the four devices, the device with address information of MAC address 2 is located in the upper right of the four devices, the device with address information of MAC address 3 is located in the lower left of the four devices, and the device with address information of MAC address 4 is located in the lower right of the four devices. Then, after obtaining the image information, the smart TV 1 can segment the image information into four image information (the upper left image, the upper right image, the lower left image, and the lower right image). The smart TV 1 can display the upper left image through the display screen, send the upper right image to the device with address information of MAC address 2 for display, send the lower left image to the device with address information of MAC address 3 for display, and send the lower right image to the device with address information of MAC address 4 for display.

[0204] In one embodiment, after receiving the indication information, the smart TV 1 can determine that the smart TV 1 is the master device, and the smart TV 1 can notify other smart TVs to close the device discovery (or, notify other smart devices to stop entering the waiting discovery state). After receiving the notification from the smart TV 1, the other smart TVs can close the device discovery.

[0205] As shown in (f) of FIG. 10B, the smart TV 1 can display a GUI as shown in (g) of FIG. 10B, which is a video playing interface including a video display window 1009 and a screen projection control 1010. In response to detecting a user's operation of clicking the control 1010, the smart TV 1 can display a GUI as shown in (h) of FIG. 10B. Figure 10 Figure 10

[0206] It should be understood that the smart TV 1 and the smart TV 2 shown in (f) of FIG. 10B and the smart TV 3 and the smart TV 4 shown in (a) to (e) of FIG. 10B can be the same smart TVs, or can be different smart TVs. Figure 10 Figure 10 It should be understood that the smart TV 1 and the smart TV 2 shown in (f) of FIG. 10B and the smart TV 3 and the smart TV 4 shown in (a) to (e) of FIG. 10B can be the same smart TVs, or can be different smart TVs.

[0207] As shown in (g) of FIG. 10B, the smart TV 1 can display a prompt box 1011, in which a list of devices that can be projected is included. Since the smart TV 2, the smart TV 3 and the smart TV 4 have closed the device discovery, the list of devices that can be projected only includes the smart TV 1. In response to detecting a user's operation of selecting the smart TV 1 for projection, the smart TV 1 can send the image information in the video display window 1009 to the smart TV 1. Figure 10 As shown in (h) of FIG. 10B, in response to a user's operation of selecting the smart TV 1, the smart TV 1 can send the image information in the video display window 1009 to the smart TV 1. After receiving the image information sent by the smart TV 1, the smart TV 1 can split the image information according to the orientation information between the smart TV 1 and other smart TVs. For example, the smart TV 1 can cut each frame of the image information into 4 frames, such as a top-left image 1012, a top-right image 1013, a bottom-left image 1014 and a bottom-right image 1015.

[0208] Figure 10

[0209] ​​​​​Smart TV 1 can send the upper right image 1013 to smart TV 2 based on the orientation information of smart TV 2 and the address information of smart TV 2, so that smart TV 2 can display image 1013; smart TV 1 can send the lower left image 1014 to smart TV 3 based on the orientation information of smart TV 3 and the address information of smart TV 3, so that smart TV 3 can display image 1014; smart TV 1 can send the lower right image 1015 to smart TV 4 based on the orientation information of smart TV 4 and the address information of smart TV 4, so that smart TV 4 can display image 1015; smart TV 1 can display the upper left image 1012.

[0210] In this embodiment, multiple small screens can be combined into a single large screen without requiring any additional hardware, and there are no requirements for screen installation, which helps save hardware costs. Users can select a single screen from multiple small screens as the master screen, which can then be used to split and distribute images, improving the user experience.

When the mobile phone detects that the user clicks the large-screen combination display function 1102, the mobile phone can display the following Figure 11 The GUI shown in (b) in FIG.

[0213] In one embodiment, in response to detecting a user clicking on the large-screen combined display function 1102, the mobile phone may send a broadcast message to devices within the same local area network as the mobile phone, instructing the electronic devices to enter the combined display state. In response to receiving the broadcast message, Smart TV 1, Smart TV 2, Smart TV 3, and Smart TV 4 may display a QR code on their display screens, wherein the QR code displayed by each smart TV indicates its address information (e.g., MAC address).

[0214] like Figure 11As shown in (b) of FIG. 11, in response to the operation of the user selecting the large-screen combination display function 1102, the mobile phone can start the camera and display the prompt information "Please place the electronic devices that need to be combination displayed in the following preview frame". The mobile phone can display the information of the multiple devices captured by the camera of the mobile phone in the preview frame 1103. When the mobile phone detects the operation of the user clicking the control 1104, the mobile phone can determine the address information of the multiple smart TVs through the two-dimensional code information displayed on the multiple smart TVs in the preview frame 1103, and at the same time, the mobile phone can also determine the orientation information of each smart TV through the image information in the preview frame 1103.

[0215] It should be understood that the process after the mobile phone detects the operation of the user clicking the control 1104 can refer to the GUI shown in (e) to (h) of FIG. 11. Figure 10 For brevity, details are not repeated here.
