[0048] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0049] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0050] The present disclosure provides a screen projection control method, which is introduced below in conjunction with a specific embodiment.

[0051] Figure 1 A flow chart of a screen projection control method provided in an embodiment of the present disclosure. The method can be applied to an electronic device with a display screen. Specifically, the electronic device can be a terminal, such as a smart phone, a PDA, a tablet computer, a vehicle-mounted terminal, a wearable device with a display screen, a desktop computer, a laptop computer, an all-in-one machine, a smart home device, etc. Figure 2 and Figure 3 This is a schematic diagram of the screen projection interface provided in the embodiment of the present disclosure. Figure 2 as well as Figure 3 The screen projection control method provided by the embodiment of the present disclosure is introduced, and the specific steps of the method are as follows:

[0052] S101. Display a screen projection interface, where the screen projection interface is used to play a screen projection signal received from an external device.

[0053] like Figure 2As shown in the schematic diagram of the screen projection interface, after the terminal establishes a communication connection with the external device, the terminal receives the screen projection signal sent by the external device and displays the image to be projected on the external device in real time on the screen projection interface.

[0054] S102. In response to the user's operation on the screen projection interface, display multiple application icons.

[0055] like Figure 3 As shown in the schematic diagram of the screen projection interface, during the screen projection process, the user can call out the taskbar by touching the screen projection interface. The taskbar displays multiple application icons, corresponding to multiple applications, such as screen projection applications, navigation applications, audio and video entertainment applications, etc. You can also return to the desktop of the terminal display by clicking the desktop icon in the taskbar. If the taskbar is called out for a period of time without receiving the user's operation or instruction, the taskbar disappears automatically. For example, the user can swipe up at the bottom of the screen projection interface to call out the taskbar, but of course it is not limited to this.

[0056] S103. In response to a user operation on a target application icon among the multiple application icons, a target interface corresponding to the target application icon is displayed, where the target application icon is an icon of an application other than the projection application.

[0057] The user selects the icon of the target application that he needs to use from multiple application icons and clicks on it, and the display interface of the terminal switches from the projection interface to the interface corresponding to the target application. It is understandable that when the user needs to switch back to the projection interface from the target application interface, he can also return to the projection interface by clicking the projection application icon from the taskbar.

[0058] The disclosed embodiment displays a projection interface, which is used to play a projection signal received from an external device; displays multiple application icons in response to user operations on the projection interface; and displays a target interface corresponding to the target application icon in response to user operations on a target application icon among the multiple application icons, wherein the target application icon is an icon of an application other than the projection application. The projection function is displayed in the form of an application on the display screen of the terminal to ensure that the user can switch to the interface of other applications during the projection process, thereby improving the flexibility of the projection control method, meeting user needs, and improving the user experience.

[0059] Figure 4 This is a schematic diagram of the automatic screen projection function setting interface provided by the embodiment of the present disclosure. Figure 4As shown, on the basis of the above embodiment, if the projection control mode of the projection application is automatic projection mode when the projection signal is received, the projection application is started and the projection interface is displayed; if the projection control mode of the projection application is non-automatic projection mode when the projection signal is received, then in response to the user's operation on the projection application icon, the projection application is started and the projection interface is displayed.

[0060] Users can click on Figure 2 Click the Settings icon in the screen projection interface to enter the settings interface and set the functions of the screen projection application. Figure 4 As shown, the automatic screen projection function includes two states: on and off. When the automatic screen projection function is on, the screen projection application is in automatic screen projection mode. At this time, when the terminal receives a screen projection signal from an external device, the screen projection application is directly started and the corresponding screen projection interface is displayed. When the automatic screen projection function is off, the screen projection application is in non-automatic screen projection mode. At this time, when the terminal receives a screen projection signal from an external device, the screen projection application will not be started, nor will the corresponding screen projection interface be displayed, until the user actively opens the screen projection application by clicking on the screen projection application icon, etc., in response to the user's operation on the screen projection application icon, the screen projection application is started and the corresponding screen projection interface is displayed.

[0061] The disclosed embodiment sets an automatic screen projection function switch. If the projection control mode of the projection application is the automatic projection mode when the projection signal is received, the projection application is started and the projection interface is displayed; if the projection control mode of the projection application is the non-automatic projection mode when the projection signal is received, the projection application is started in response to the user's operation on the projection application icon, and the projection interface is displayed, so that the user can make settings according to his or her own usage habits, so that the projection function can better meet user needs, further improving the flexibility of the projection control method.

[0062] Figure 5 This is a schematic diagram of the screen projection signal search interface provided by the embodiment of the present disclosure. Figure 5 As shown, in some embodiments, before displaying the screen projection interface, the screen projection control method further includes: if the screen projection signal is not received when the screen projection application is started, then displaying the screen projection signal search interface, the screen projection signal search interface including a search prompt image; correspondingly, displaying the screen projection interface includes: when the screen projection signal is searched, displaying the screen projection interface. Specifically, the screen projection signal search interface also includes a control icon for the screen projection control mode of the screen projection application.

[0063] When the user actively clicks the screen projection application icon to start the screen projection application, if the terminal does not receive the screen projection signal from the external device, the following display will be displayed: Figure 5 The screen projection signal search interface shown guides the user to connect the external device to the terminal through the corresponding interface or other connection methods. The screen projection signal search interface includes a search prompt image, which can be dynamic, with multiple dotted lines dynamically displayed around the interface icon, simulating the search of the screen projection signal, and displaying the prompt "Searching for signal..." to prompt the user that the screen projection signal from the external device is not currently received, and the corresponding transmission interface such as the DP (DisplayPort) interface is waiting for the screen projection signal input. Of course, the search prompt image and prompt can also be other styles. At the same time, the terminal continues to detect whether there is a screen projection signal input from an external device in a certain frequency cycle. When the screen projection signal input from the external device is received, the corresponding screen projection interface is immediately displayed. In addition, the screen projection signal search interface also includes a control icon for the screen projection control mode of the screen projection application, which is used to control the opening or closing of the automatic screen projection mode according to the user setting. Specifically, the function and control method of the automatic screen projection mode are consistent with the above-mentioned embodiment, which will not be repeated here.

[0064] The disclosed embodiment displays a screen projection signal search interface if no screen projection signal is received when the screen projection application is started, and the screen projection signal search interface includes a search prompt image; accordingly, the screen projection interface is displayed, including: when the screen projection signal is searched, the screen projection interface is displayed. Specifically, the screen projection signal search interface also includes a control icon of the screen projection control mode of the screen projection application, prompting the user that no screen projection signal is currently received, combined with the search prompt image to remind the user that it is waiting for the input of the screen projection signal, guiding the user to connect the external device, and providing a good interactive experience for the user.

[0065] Figure 6 and Figure 7 This is a schematic diagram of the full-screen mode projection interface provided by the embodiment of the present disclosure. Figure 6 As shown, on the basis of the above embodiment, if no user instruction is received within the first preset time after the projection interface of the non-full-screen mode is displayed, the projection interface of the full-screen mode is displayed; in response to the user's operation in the projection interface of the full-screen mode, the projection interface of the non-full-screen mode is displayed.

[0066] When the terminal displays Figure 2 After the non-full screen mode projection interface shown in FIG. 1 continues for a first preset time, if no user command is received during this period of time, the following is displayed: Figure 6 In response to any operation of the user in the projection interface in the full-screen mode, switching to Figure 2 The non-full screen mode screen projection interface shown in the figure. Figure 7As shown in the figure, when the full-screen projection interface is displayed, the user can still call out the taskbar by swiping up from the bottom of the screen, and quickly switch to the desktop or other application interface by clicking the desktop icon or other application icon in the taskbar. If the taskbar is called out for a period of time without receiving any user operation or instruction, the taskbar will automatically disappear.

[0067] Figure 8 Schematic diagram of the screen projection confirmation interface provided in an embodiment of the present disclosure. In some embodiments, when the user ends the screen projection by operating the end screen projection option in the screen projection interface in non-full screen mode, a pop-up window such as Figure 8 The screen projection confirmation interface shown in the figure reminds the user to confirm whether to end the screen projection. If the user is sure to end the screen projection, the screen projection application will be closed and the page before entering the screen projection will be returned. At the same time, the screen projection signal sent by the external device will no longer be received. If the user cancels the screen projection, the screen projection will return to the following interface. Figure 2 In the non-full-screen mode projection interface shown, the projection signal sent by the external device continues to be received and the corresponding projection interface is displayed.

[0068] The disclosed embodiment displays the projection interface of the full-screen mode if no user instruction is received within the first preset time after the projection interface of the non-full-screen mode is displayed; in response to the user's operation in the projection interface of the full-screen mode, the projection interface of the non-full-screen mode is displayed, and the projection interface of the non-full-screen mode is switched to the projection interface of the full-screen mode in a timely manner, thereby providing the user with a better projection viewing experience. At the same time, the projection interface of the full-screen mode can also be switched to other application interfaces, thereby ensuring the flexibility of the projection control method. In addition, the disclosed embodiment avoids the problem of abnormal interruption of projection caused by user's accidental touch by setting a confirmation interface for ending projection, thereby further ensuring the user's experience.

[0069] In some embodiments, after displaying the target interface corresponding to the target application icon, the screen projection control method also includes: stopping playing the screen projection signal; if no user instruction to display the screen projection interface is detected within a second preset time after displaying the target interface, stopping receiving the screen projection signal and charging the external device.

[0070] When the user leaves the projection interface, such as switching to the target interface corresponding to the target application icon or switching to the desktop, the terminal stops playing the projection signal received from the external device, including stopping playing the video signal and the audio signal. When the user leaves the projection interface for more than a second preset time, such as switching to the target interface corresponding to the target application icon or switching to the desktop for more than a second preset time, the terminal cuts off the projection signal from the external device, no longer receives the projection signal sent by the external device, and only charges the external device until the user opens the projection application again, and restores the corresponding projection interface. It can be understood that while receiving the projection signal sent by the external device and displaying the corresponding projection interface, the terminal can also charge the external device.

[0071] When multiple terminals are projecting screens at the same time, these terminals all play audio through the in-car speakers, and only when the terminal displays the projection interface, that is, when the projection application is running in the foreground, will the audio of the projection interface be played. When the projection application in any terminal switches to the background, or the terminal is off, stop playing the audio of the projection interface of the terminal or stop playing the audio of the terminal. In some vehicles, the driver can control the music playback by adjusting the volume control on the media center console. For example, if the in-car speakers are not playing music, pressing the volume up button can quickly play music. When the vehicle terminal plays the audio corresponding to the projection interface through the in-car speakers, the volume control on the media center console is configured to adjust the sound of the current in-car speakers, disabling its function of quickly playing music.

[0072] The disclosed embodiment stops receiving the screen projection signal and charging the external device when no instruction from the user to display the screen projection interface is detected within a second preset time after the target interface is displayed. When the user does not need to use the screen projection function, the screen projection signal of the external device is promptly cut off, and the external device is charged in a charging-only mode, thereby saving power and power consumption of the external device. At the same time, the screen projection interface can be quickly restored by simply opening the screen projection application again, thereby further improving the flexibility of the screen projection control method.

[0073] In addition, the disclosed embodiment adapts the vehicle's media center console to avoid the shortcut functions of the media center console causing erroneous control of the sound playback of the projection interface or affecting the sound playback of the projection interface, thereby ensuring a good user experience.
