[0006] Based on the above technical solution, users can control the large-screen device by scanning the QR code displayed on the large-screen device through the electronic device, without the need for voice interaction, thus avoiding affecting other users when controlling the large-screen device, and helping to improve the user experience when controlling the large-screen device; at the same time, since the QR code carries authentication information, the large-screen device can authenticate the electronic device through the authentication information. During the interaction between the electronic device and the large-screen device, the electronic device can encrypt the control command through the authentication information, which helps to improve the security when controlling the large-screen device.

[0007] In some possible implementations, the electronic device may establish a Bluetooth connection with the large-screen device based on the address information, or the electronic device may establish a StarFlash connection with the large-screen device based on the address information.

[0008] In some possible implementations, the large-screen device is used to generate the authentication information when powered on and to generate the QR code according to the address information of the large-screen device and the authentication information.

[0009] In combination with the first aspect, in certain implementations of the first aspect, the electronic device is further used to control the display screen to hide the display interface of the remote control service when the connection with the large-screen device is disconnected.

[0010] Based on the above technical solution, when the electronic device is disconnected from the large-screen device, the electronic device can automatically hide the display interface of the remote control service without the user having to manually hide the display interface, which helps to improve the user experience.

[0011] In combination with the first aspect, in certain implementations of the first aspect, the electronic device is further used to control the display screen to display the display interface of the remote control service when establishing a connection with the large-screen device again.

The processor 210 can control the movement of the cursor on the display screen 220 according to the control command, or control the cursor to select a multimedia file or a multimedia application.

[0096] Figure 3It is a set of graphical user interfaces (GUI) provided in the embodiments of the present application.

[0097] like Figure 3 As shown in (a) of FIG. 1 , the rear entertainment screen 201 in the vehicle can display a QR code 202 after being powered on. Exemplarily, the QR code 202 may include device information (e.g., device name), address information (e.g., media access control (MAC) address), authentication information (e.g., 6-digit random number), etc. of the rear entertainment screen. The rear user is sitting in the right area of ​​the second row of the vehicle and is ready to use a mobile phone to scan the QR code 202 on the rear entertainment screen 201.

[0098] like Figure 3 As shown in (b) of FIG. 1 , the GUI is a display interface of a social application on the electronic device of the back row user. The display interface includes a control 203. When the user clicks the control 203, the mobile phone may display the following Figure 3 The display interface shown in (c) .

[0099] like Figure 3 As shown in (c) of FIG. 1 , the GUI is another display interface of the social application. In response to detecting that the user clicks on the control 203, the mobile phone can display a function bar 204, wherein the function bar 204 includes the add friend function, the scan function 205, the start group chat function, and the payment function. When detecting that the user clicks on the scan function 205, the mobile phone can display the following Figure 3 GUI shown in (d).

[0100] like Figure 3 As shown in (d) in the figure, the GUI is a display interface of the scan function. The rear users can aim the scanning box 206 on the display interface at the QR code 202 on the rear entertainment screen. After the mobile phone recognizes the QR code 202, it can obtain the device information (for example, the device name), address information, authentication information, etc. of the rear entertainment screen. The mobile phone can establish a connection with the rear entertainment screen based on the address information. At the same time, the mobile phone can request the corresponding remote control applet from the cloud server. When the mobile phone receives the information of the remote control applet sent by the cloud server, the mobile phone can display the following information: Figure 3 GUI shown in (e) in .

[0101] The above authentication information does not rely on Bluetooth security and can be used for device connection authentication and session data encryption, which helps to improve the safety of users when using mobile phones to control the rear entertainment screen.

[0102] In one embodiment, the mobile phone can establish a Bluetooth low energy (BLE) connection with the rear entertainment screen based on the address information therein, or establish a connection based on the Star Flash protocol.

[0103] In one embodiment, after the mobile phone and the rear entertainment screen are connected, the rear entertainment screen can switch from displaying the QR code 202 to displaying the multimedia application.

[0104] like Figure 3 As shown in (e) in the figure, the GUI is the display interface of the remote control applet in the social application. In response to receiving the information of the remote control applet sent by the cloud server, the mobile phone can display the display interface of the remote control applet. The display interface includes multiple function controls, such as switch, mute, input, setting, extension key, change channel, turn down or turn up the volume, return, and control the cursor to move in different directions.

[0105] For example, when the user clicks on the control 207, the mobile phone can send a control command encrypted by the authentication information to the rear entertainment screen, and the control command instructs the cursor on the rear entertainment screen 201 to move upward. After receiving the control command, the rear entertainment screen 201 can decrypt the encrypted control command and control the cursor to move upward according to the control command.

[0106] In an embodiment of the present application, a user can use a mobile phone to scan the QR code on the rear entertainment screen, so that the mobile phone can obtain the address information of the rear entertainment screen and establish a wireless connection with the rear entertainment screen. At the same time, the mobile phone can also automatically request the remote control applet from the cloud server. After the mobile phone obtains the remote control applet, the remote control applet can be displayed, making it convenient for the user to control the rear entertainment screen through the remote control applet. In this way, there is no need for the user to download the corresponding remote control application before controlling the rear entertainment screen, which helps to avoid cumbersome operations when the user controls the rear entertainment screen; at the same time, there is no need to configure a physical remote control in the vehicle, which also helps to reduce the hardware cost of the vehicle.

[0107] Figure 4 This is another set of GUIs provided by an embodiment of the present application.

[0108] like Figure 4 As shown in (a) of FIG. 1 , the GUI is the desktop of the mobile phone. When the mobile phone detects that the user slides to the right at any position of the first desktop page, the mobile phone can display the following Figure 4 GUI shown in (b) in .

[0109] like Figure 4As shown in (b) of FIG. 1 , in response to detecting that the user swipes rightward at any position of the first desktop page, the mobile phone can display a display interface of the negative one screen. The display interface of the negative one screen includes an icon 301 of the scan function. When the user clicks the icon 301, the following display interface can be displayed: Figure 4 GUI shown in (c) in FIG.

[0110] It should be understood that in the embodiment of the present application, the negative one screen refers to the desktop of the user's mobile phone (such as Figure 4 The interface displayed after detecting a user sliding right on the desktop of the mobile phone shown in (a). Figure 4 The desktop of the mobile phone shown in (a) may be the second desktop page on the desktop of the mobile phone, and the negative one screen may be the first desktop page on the desktop of the mobile phone, such as Figure 4 The negative first screen can provide users with services such as search, application suggestions, quick services, missed call notification cards, and express query, or the negative first screen can display some applications (Apps) that users frequently use.

[0111] like Figure 4 As shown in (c) in the figure, the GUI is a display interface of the scan function. The user can align the scanning box 302 on the display interface with the QR code 202 on the rear entertainment screen. After the mobile phone recognizes the QR code 202, it can obtain the device information, address information, authentication information, etc. of the rear entertainment screen. The mobile phone can establish a connection with the rear entertainment screen based on the address information. At the same time, the mobile phone can request the remote control service card information from the cloud server. When the mobile phone receives the remote control service card information sent by the cloud server, the mobile phone can display the following information: Figure 4 GUI shown in (d).

[0112] like Figure 4 As shown in (d) in FIG. 1 , the GUI is a display interface of a remote control service card in a social application. In response to receiving information of a remote control service card sent by a cloud server, the mobile phone can display the display interface of the remote control service card.

[0113] In an embodiment of the present application, the user can use the scanning function on the negative one screen to scan the QR code on the rear entertainment screen, so that the mobile phone can obtain the address information of the rear entertainment screen and establish a wireless connection with the rear entertainment screen. At the same time, the mobile phone can also automatically request a remote control service card from the cloud server. After the mobile phone obtains the remote control service card, the remote control service card can be displayed to facilitate the user to control the rear entertainment screen through the remote control service card. In this way, the user does not need to download the corresponding remote control application before controlling the rear entertainment screen, which helps to avoid cumbersome operations when the user controls the rear entertainment screen; at the same time, there is no need to configure a physical remote control in the vehicle, which also helps to reduce the hardware cost of the vehicle.

[0114] above Figure 4 The example of identifying the QR code through the scan function on the negative screen is used for illustration, and the present application is not limited thereto. For example, the QR code can also be identified through the scan function in the camera application or the account application, so that the mobile phone can display the display interface of the remote control service card.

[0115] Above through Figure 3 and Figure 4 The GUI shown in the figure introduces how to establish a connection with the rear entertainment screen and control the rear entertainment screen by scanning a QR code when the mobile phone and the rear entertainment screen have not been connected before. Figure 5 and Figure 6 This section introduces the process of controlling the rear entertainment screen when a mobile phone has previously established a connection with the rear entertainment screen.

[0116] Figure 5 This is another set of GUIs provided by an embodiment of the present application.

[0117] like Figure 5 As shown in (a) of FIG. 1 , the GUI is a display interface of a social application. When a user slides down on the display interface, the mobile phone may display the following Figure 5 The display interface shown in (b).

[0118] Since the mobile phone and the rear entertainment screen both save the device information and address information of the other device during the first connection process, when the user brings the mobile phone close to the rear entertainment screen again, the mobile phone and the rear entertainment screen can establish a connection directly.

[0119] like Figure 5 As shown in (b) of FIG. 1 , in response to detecting a user's downward sliding operation, the mobile phone can display information of the most recently used mini-programs. For example, the most recently used mini-programs include remote control mini-programs, mini-program 1, mini-program 2, mini-program 3, mini-program 4, and mini-program 5. When detecting a user's clicking operation on the remote control mini-program, the following information can be displayed: Figure 5 GUI shown in (c) in FIG.

[0120] like Figure 5 As shown in (c) in the figure, the GUI is the display interface of the remote control applet in the social application. In response to detecting that the user clicks on the remote control applet, the mobile phone can display the display interface of the remote control applet and send a broadcast message to surrounding devices, and the broadcast message may include the device information of the mobile phone. When the rear entertainment screen receives the broadcast message, it can determine the device information of the mobile phone according to the broadcast message and can determine that a connection has been established with the mobile phone according to the device information of the mobile phone. The rear entertainment screen can send a connection request to the mobile phone according to the address information of the mobile phone and establish a connection with the mobile phone. Thereby, the mobile phone can once again control the rear entertainment screen through the display interface of the remote control applet.

[0121] In one embodiment, when the rear entertainment screen is powered on again, a broadcast message may be sent to surrounding devices, and the broadcast message may include the device information of the rear entertainment screen. When the mobile phone receives the broadcast message, it may determine the device information of the rear entertainment screen based on the broadcast message and may determine that a connection has been established with the rear entertainment screen based on the device information of the rear entertainment screen. The mobile phone may send a connection request to the rear entertainment screen based on the address information of the rear entertainment screen, and may directly display the following information after the connection is established with the rear entertainment screen: Figure 5 GUI shown in (c) in FIG.

[0122] Figure 6 It is another GUI provided by an embodiment of the present application.

[0123] like Figure 6 As shown, after the mobile phone and the rear entertainment screen are connected for the first time and the mobile phone obtains the information of the remote control service card from the cloud server, the mobile phone can display the remote control service card 601 on the display interface of the negative one screen. After the mobile phone and the rear entertainment screen are connected again, the service card 601 can display "The rear entertainment screen has been connected. Click the service card to control the rear entertainment screen."

[0124] Exemplarily, when detecting that the user clicks on the card 601, the mobile phone may display a display interface of the remote control service card.

[0125] Combination of the above Figure 3 and Figure 4 This article introduces the process of users controlling the rear entertainment screen by scanning the QR code with their mobile phones. Figure 7 The GUI shown introduces another way to control the rear entertainment screen.

[0126] Figure 7 This is another set of GUIs provided by an embodiment of the present application.

[0127] See also Figure 7In the GUI shown in (a), the rear entertainment screen can send a BLE broadcast message to surrounding devices after powering on. The BLE broadcast message includes the device information and address information of the rear entertainment screen. When the mobile phone receives the broadcast message sent by the rear entertainment screen, the mobile phone can display icon 701 on the lock screen interface. When the mobile phone detects that the user clicks on icon 701, it can display the following Figure 7 GUI shown in (b) in .

[0128] In one embodiment, when the mobile phone detects that the user clicks on icon 701, the mobile phone can establish a connection with the rear entertainment screen according to the address information of the rear entertainment screen carried in the broadcast message.

[0129] See also Figure 7 The GUI shown in (b) is the display interface after the mobile phone detects that the user has clicked on icon 701. The mobile phone can display a touch panel 702, a return to home page control 703, and a return to the previous page control 704 on the lock screen interface. The user can perform operations (for example, sliding, clicking, etc.) on the touch panel 702. When the mobile phone detects that the user has performed a corresponding operation on the touch panel 702, the mobile phone can send a control command to the rear entertainment screen, which can be used to indicate the operation. The rear entertainment screen can perform the corresponding operation according to the control command.

[0130] In the embodiment of the present application, when the mobile phone receives the broadcast message sent by the rear entertainment screen, the icon can be used to prompt the user that the rear entertainment screen can be controlled through the mobile phone, so that the rear entertainment screen can be controlled in the lock screen state without the need for the mobile phone to enter the unlocked screen state and the mobile phone to start the remote control application. The mobile phone can control the rear entertainment screen in the lock screen interface, which helps to improve the convenience of the user when controlling the rear entertainment screen, thereby improving the user experience.

[0131] like Figure 7 The GUI shown in (c) in the figure is the display interface after the mobile phone detects that the user has clicked on icon 701. When the mobile phone detects that the user has clicked on icon 701, the mobile phone can turn on the camera to collect the user's facial information. If the facial information collected by the camera matches the facial information preset in the mobile phone, the mobile phone can be unlocked first to enter the non-lock screen interface, and automatically display the touch panel 702, the return homepage control 703, and the return to the previous page control 704 in the non-lock screen interface. Alternatively, when the mobile phone detects that the user has clicked on icon 701, the mobile phone can collect the user's fingerprint information. If the collected fingerprint information matches the fingerprint information preset in the mobile phone, the mobile phone can be unlocked first to enter the non-lock screen interface, and automatically display the touch panel 702, the return homepage control 703, and the return to the previous page control 704 in the non-lock screen interface.

[0132] Several groups of GUIs in the embodiments of the present application are introduced above. The following describes the interaction process between the electronic device 100 and the large-screen device 200 in the embodiments of the present application in conjunction with the accompanying drawings.

[0133] Figure 8 A schematic flow chart of a control method 800 provided in an embodiment of the present application is shown. The method 800 may be performed by an electronic device 100 (eg, a mobile phone) and a large-screen device 200. The method 800 includes:

[0134] S801, when the large-screen device 200 is powered on, the processor 210 generates information of a two-dimensional code and sends the information of the two-dimensional code to the display screen 220.

[0135] Exemplarily, the two-dimensional code information includes device information of the large-screen device 200 (for example, the name of the large-screen device, device identification), address information, and authentication information.

[0136] S802, the display screen 220 displays the two-dimensional code information.

[0137] For example, Figure 3 As shown in (a) in the figure, the rear entertainment screen 201 can display the QR code 202.

[0138] S803, the processor 110 acquires and recognizes the information of the QR code through the image captured by the camera 193, and obtains the device information, address information and authentication information of the large-screen device 200.

[0139] For example, Figure 3 As shown in (d) in the figure, the mobile phone can identify the QR code 202 displayed on the rear entertainment screen 201 through the scan function in the social application, thereby obtaining the device information, address information and authentication information of the large-screen device.

[0140] For example, Figure 4 As shown in (c), the mobile phone can identify the QR code 202 displayed on the rear entertainment screen 201 through the scan function on the negative first screen, thereby obtaining the device information, address information and authentication information of the large-screen device.

[0141] S804 , the processor 110 sends the address information of the large-screen device 200 to the wireless communication module 160 .

[0142] Exemplarily, the address information of the large-screen device may be the MAC address of the large-screen device 200 .

[0143] S805 , the wireless communication module 160 establishes a wireless connection with the wireless communication module 230 in the large-screen device 200 according to the address information of the large-screen device 200 .

[0144] Exemplarily, the wireless communication module 160 can establish a BLE connection or a StarFlash connection with the wireless communication module 230 according to the address information of the large-screen device 200 .

[0145] Exemplarily, the wireless communication module 160 may send a connection request to the wireless communication module 230 based on the address information, and the connection request includes a character string 1. The wireless communication module 230 may establish a BLE connection with the wireless communication module 160 based on the connection request.

[0146] S806, after the wireless communication module 160 establishes a connection with the wireless communication module 230, the processor 110 controls the wireless communication module 160 to send an authentication request to the wireless communication module 230, where the authentication request includes a character string 1 encrypted by the authentication information.

[0147] S807 , the wireless communication module 230 may send the authentication request to the processor 210 .

[0148] S808: The processor 210 may decrypt the character string 1 encrypted by the authentication information to obtain the character string 1.

[0149] If the string 1 matches the string in the connection request, the processor 230 may determine that the authentication of the electronic device 100 is successful. If the string 1 does not match the string in the connection request, the processor 230 may determine that the authentication of the electronic device 100 fails.

[0150] The above S806 - S808 can be understood as the authentication process of the large-screen device 200 to the electronic device 100 .

[0151] S809, the wireless communication module 160 records the information of the large-screen device 200.

[0152] Exemplarily, the wireless communication module 160 can record the device information, address information and authentication information of the large-screen device 200 .

[0153] S810 , the wireless communication module 230 records information of the electronic device 100 .

[0154] Exemplarily, the wireless communication module 230 may record device information and address information of the electronic device 100 .

[0155] There is no actual order of precedence between S809 and S810 above.

[0156] S811, when the processor 110 obtains the device information of the large-screen device 200 (for example, the large-screen device) through QR code recognition, it can control the wireless communication module 160 to request the cloud server for the information corresponding to the remote control service.

[0157] S812, the wireless communication module 160 receives information corresponding to the remote control service sent by the cloud server.

[0158] S813, the wireless communication module 160 sends information corresponding to the remote control service to the processor 110.

[0159] For example, Figure 3 As shown in (d) in FIG. 1 , when the QR code 202 is recognized by the scan function in the social application, a request message may be sent to the server corresponding to the social application, and the request message is used to request the information corresponding to the remote control applet. The cloud server may send the information corresponding to the remote control applet to the wireless communication module 160.

[0160] For example, Figure 4 As shown in (c) in FIG. 1 , when the QR code 202 is recognized by the scan function in the negative first screen, the remote control service card can be requested from the application center. The cloud server can send the remote control service card information to the wireless communication module 160 .

[0161] S814, the processor 110 controls the display screen 194 to display the display interface of the remote control service.

[0162] For example, Figure 3 As shown in (e), after receiving the information of the remote control applet sent by the cloud server, the mobile phone can display the remote control applet.

[0163] For example, Figure 4 As shown in (d), after receiving the information of the remote control service card sent by the cloud server, the mobile phone can display the remote control service card.

[0164] S815: The processor 110 obtains the user input on the display interface of the remote control service.

[0165] For example, Figure 3 As shown in (e) in FIG. 8 , the remote control panel service obtains the input of the user clicking the control 207 .

[0166] S816, the processor 110 controls the wireless communication module 160 to send a control command encrypted by the authentication information to the wireless communication module 230, where the control command is used to indicate the input.

[0167] S817, the wireless communication module 230 sends the control command encrypted by the authentication information to the processor 210.

[0168] S818, the processor 210 decrypts the control command encrypted by the authentication information and controls the display screen 220 to perform corresponding operations according to the control command.

[0169] For example, in response to the input, the processor 210 may control the movement of a cursor on the display screen 220 .

[0170] S801-S818 above are the process of the electronic device 100 and the large screen device 200 being connected for the first time and the electronic device 100 controlling the large screen device 200. The following describes the process of the electronic device 100 controlling the large screen device 200 during the non-first connection between the electronic device 100 and the large screen device 200 in combination with S819-S827.

[0171] S819, the wireless communication module 160 re-establishes a wireless connection with the wireless communication module 230 according to the address information of the large-screen device 200.

[0172] Exemplarily, after the large-screen device 200 is powered on again, a BLE broadcast message is sent to surrounding devices through the wireless communication module 230, and the BLE broadcast message includes the device information of the large-screen device 200. After receiving the BLE broadcast message, the wireless communication module 160 can establish a BLE connection with the wireless communication module 230 again, or a star flash connection, according to the address information of the large-screen device stored in the wireless communication module 160.

[0173] S820, when the wireless communication module 160 and the wireless communication module 230 establish a wireless connection again, the processor 110 can control the wireless communication module 160 to request the cloud server for information corresponding to the remote control service.

[0174] Optionally, when the wireless communication module 160 and the wireless communication module 230 establish a wireless connection again, the processor 110 can control the display screen 194 to prompt the user whether to control the large-screen device 200. When the processor 110 obtains the user's input to determine to control the large-screen device 200, it can control the wireless communication module 160 to request the cloud server for information corresponding to the remote control service.

[0175] S821, the wireless communication module 160 receives information corresponding to the remote control service sent by the cloud server.

[0176] S822, the wireless communication module 160 sends information corresponding to the remote control service to the processor 110.

[0181] S827, the processor 210 decrypts the control command encrypted by the authentication information and controls the display screen 220 to perform corresponding operations according to the control command.

[0182] After the electronic device 100 and the large-screen device 200 are connected again, the electronic device 100 can directly display the display interface of the remote control service, and the user can directly control the large-screen device 200 through the display interface of the remote control service.

[0183] Above through Figure 8 The process of establishing a connection between the electronic device 100 and the large-screen device 200 after recognizing the QR code is introduced. Fig. 9 The following describes a process in which the electronic device 100 establishes a connection with the large-screen device 200 by receiving a broadcast message sent by the large-screen device 200.

[0184] Fig. 9 A schematic flow chart of a control method 900 provided in an embodiment of the present application is shown. The method 900 can be performed by the electronic device 100 and the large-screen device 200. The method 900 includes:

[0185] S901, the large-screen device 200 detects that it is powered on.

[0186] S902, the large screen device 200 sends a broadcast message, which is used to indicate that the rear entertainment screen needs to be controlled.
