It should be noted that the components depicted in the reference drawings are not necessarily shown to scale; and the same or similar components will be given the same or similar reference numerals or similar technical terms.

[0028] Reference Figure 1 The present application proposes a startup method, which is applied to an electronic device. The electronic device may be a projector, a computer, an electric vehicle, a smart watch, etc.

[0029] The boot methods include: S1: In response to a power-on operation, an initial interface is displayed and a plurality of preset application programs are started in parallel.

[0030] In this embodiment, the user can turn on the electronic device through button control, voice control, etc. After the electronic device completes the boot process, the initial interface is displayed and multiple preset applications are started at the same time. The initial interface can be the desktop interface of the electronic device, or a preset boot screen. The number and category of preset applications can be set according to actual applications. For example, basic applications such as video players, music players, and application stores can be set as preset applications. Alternatively, according to the user's preferences, several applications that the user has started more times are set as preset applications.

[0031] S2: Displaying a first icon corresponding to each preset application on the initial interface, where the first icon is used to indicate that the preset application is running in the foreground.

[0032] The first icon is used to indicate that the preset application is running in the foreground. In various operating systems (such as Android, iOS, Hongmeng, etc.), the foreground service puts the running task in the foreground state by displaying the corresponding icon in the foreground to avoid being considered as a low-priority background task and being cleared by the system. Therefore, by displaying the first icon on the initial interface, the corresponding preset program can be kept running in the background without displaying the complete interface.

[0033] Reference Figure 2 In this embodiment, multiple preset applications can be started in parallel in the background and displayed in the front-end initial interface as the first icon. In this way, by displaying the first icon on the initial interface, the operation of multiple preset applications is placed in the front-end state, so that multiple preset applications can remain running in the background to avoid being mistaken by the system as low-priority background tasks and being cleared. Among them, the shape of the first icon can be set according to the actual application, for example, set to a triangle, rectangle, circle, etc. The position of the first icon can be set at the side, corner, etc. of the initial interface to avoid blocking the main content of the initial interface.

[0034] In one embodiment, the first icon is displayed in the preset area 14 of the initial interface, and the characteristics of the first icon are similar to or the same as the characteristics of the content displayed in the preset area 14; the characteristics include one or more of color, shape, and size.

[0035] In this embodiment, the preset area 14 can be set at a suitable position according to actual application, for example, at the side or corner of the initial interface, or in a darker area that is not easily perceived by the user. It can also be set in the middle area of ​​the initial interface, or near the desktop icon, so that the user can know the preset application being started.

[0036] The color of the first icon can be set to be similar or the same as the color displayed in the preset area 14. For example, the preset area 14 is displayed in green, and the first icon can be set to the same green or a darker / lighter green. Further, the first icon can also be set to follow the background color change to maintain a color similar or the same as the background color.

[0037] The shape and size of the first icon can be set to be similar or the same as the shape and size displayed in the preset area 14. For example, if the shape displayed in the preset area 14 is a rectangle, the first icon can be set to the same rectangle, or a smaller rectangle, or set to a diamond, triangle, circle, etc., to be displayed in the preset area 14.

[0038] In addition, the color, shape, and size of the first icon can also match the content displayed in the preset area 14. Figure 3 , the content displayed in the preset area 14 includes branches and green leaves on the branches. The color, shape, and size of the first icon can be set to be similar or the same as the green leaves on the branches. Alternatively, the first icon can be set to be a red round fruit on the branch. In this way, it can be integrated with the display content in the preset area 14, so that the first icon is not easily perceived by the user.

[0039] In one embodiment, the first icon can be set to have a preset transparency. The preset transparency can be set to different values ​​according to the actual application, such as 30%, 50%, 90%, etc. In this way, the first icon can be seamlessly integrated with any background color, whether it is a dark or light background, the clarity and recognition of the icon can be maintained, thereby improving the overall visual effect, so that the user can know the startup status of the preset application. Alternatively, the first icon can also be set to be completely transparent, so that the first icon is completely integrated with the background and is not easily perceived by the user.

[0040] In one embodiment, the first icon can be set as a floating window displayed on the initial interface. The floating window allows the electronic device to view or operate another task while processing one task. By setting the floating window, the preset application corresponding to the first icon can be kept running while the initial interface is running.

[0041] The size of the first icon can be set according to actual needs. For example, the first icon can be set to the same size as the pixel of the display screen. In this way, the first icon can be displayed on the initial interface without the user's perception, so as to achieve a senseless startup for the user, and the user will not feel that he is waiting for multiple preset applications to start. After multiple preset applications are started in parallel, the user can open the preset application normally, giving the user a smooth startup experience. Alternatively, the first icon can be set to a shape that can be seen by the user, so that the user can intuitively know that the application is starting in the background, and the main content will not be blocked by the first icon.

[0042] This application displays multiple preset applications in the form of first icons on the initial interface to ensure that multiple preset applications started in parallel can remain running in the background. In this way, after booting up, multiple preset applications can be started in a short time, and users can directly use the preset applications without having to wait for the preset applications to start, giving users a smooth startup experience. In addition, the first icon indicates that the preset application is starting, and the graphics rendering resource consumption is low, effectively reducing unnecessary graphics rendering resource consumption.

[0043] Reference Figure 4 In one embodiment, the startup method further includes: S3: After the preset application is started, the application window of the preset application is displayed on the initial interface, and the first icon corresponding to the preset application is canceled.

[0044] In this embodiment, after the preset application is started, the corresponding first icon is canceled and the complete application window of the preset application is displayed. Alternatively, the first icon is restored to the complete application window display. In this way, the user can use the preset application in a short time after the boot operation, without obvious waiting or lag, and the startup process is smooth and natural, which improves the user experience.

[0045] In one embodiment, the startup method further includes: S4: In response to the startup instruction of the preset application, if the corresponding preset application has not been started, display the startup interface of the corresponding preset application, and start the corresponding preset application first; if the corresponding preset application has been started, display the application window of the corresponding preset application. Displaying the startup interface of the corresponding preset application may be restoring the floating window to a complete interface.

[0046] In this embodiment, the startup instruction of the preset application program may be a voice startup instruction, a startup instruction issued by the user through a mobile terminal or a remote controller, and the like.

[0047] In one embodiment, a second icon corresponding to each preset application is displayed on the initial interface; the second icon is used to indicate the activation of the preset application.

[0048] In this embodiment, the initial interface displays the first icon and the second icon at the same time. The first icon is used to indicate that the preset application is running in the foreground. By displaying the first icon on the initial interface, the corresponding preset program can be kept running in the background without displaying the complete interface, thereby completing the startup. The second icon can be a desktop icon. When the second icon is selected, the electronic device executes the startup operation of the corresponding preset application.

[0049] If the user issues a startup instruction for a preset application while multiple preset applications are being started in parallel, the electronic device can respond immediately, switch to the interface of the corresponding preset application, and start the preset application first to provide a smooth user experience.

[0050] For example, refer to Figure 2 On the initial interface, the second icon 12a, the second icon 12b, and the second icon 12c are displayed for the video player, the music player, and the application store, respectively. After the electronic device is turned on, when the video player, the music player, and the application store are being started in parallel, the first icon 11a, the first icon 11b, and the first icon 11c are displayed on the initial interface, respectively. Reference Figure 5 If the user selects the second icon 12a corresponding to the video player, the display will be immediately switched to the startup interface of the video player, and the video player will be started first to ensure that the video player is started quickly. Figure 6 If the video player has been started, it will immediately switch to the application window of the video player. Through dynamic scheduling and priority management, resource allocation can be effectively balanced to ensure stable performance during the loading of multiple applications.

[0051] In one embodiment, the startup method further includes: S7: When the initial interface displays the third icon 13 corresponding to the first application, in response to the selection operation of the third icon 13, the first application is started first and the startup interface of the first application is displayed. The third icon 13 is used to indicate the startup of the first application.

[0052] In this embodiment, the first application may be an application other than the preset application, such as a short video application, a shopping application, etc. The third icon 13 is used to enable the electronic device to execute the corresponding startup operation of the first application when triggered. If the user selects the third icon 13 during the parallel startup of multiple preset applications, the electronic device can respond to the user's operation immediately, start the first application first, and display the startup interface of the first application.

[0053] Reference Figure 7 The present application also proposes a projection device. The projection device includes a control unit and a projection unit. The control unit is used to start multiple preset applications in parallel when the projection device is turned on. The control unit is also used to control the projection unit to display an initial interface when the projection device is turned on, and to display a first icon corresponding to each preset application on the initial interface, wherein the first icon is used to indicate that the preset application is running in the foreground.

[0054] In this embodiment, the control unit can be implemented by a microprocessor, a field effect programmable logic array (FPGA), a digital signal processor (DSP), a system-on-chip (SoC), etc. The user can send a power-on command by operating a button on the projection device, a mobile terminal, or a remote control device, and the control device can receive the power-on command and display an initial interface, and start multiple preset applications in parallel.

[0055] The number and categories of preset applications can be set according to actual applications. For example, basic applications such as video players, music players, and application stores can be set as preset applications. Alternatively, based on user preferences, several applications that are launched more frequently by users can be set as preset applications.

[0056] The parallel startup of multiple preset applications can be performed in the background and displayed in the front-end initial interface as the first icon. In this way, by displaying the first icon on the initial interface, the operation of multiple preset applications is placed in the front-end state, so that multiple preset applications can remain running in the background to avoid being mistaken by the system as low-priority background tasks and being cleared away. The preset application can be started up in a short time after the projection device is turned on, so that the user can use it directly, reducing the time the user waits for startup and bringing the user a smooth user experience. Among them, the position of the first icon can be set at the side, corner, etc. of the initial interface to avoid blocking the main content of the initial interface.

The input interface 235 includes a circuit that outputs the operation signals input from the operation unit 231 to the control unit 250.

[0067] After receiving a signal (such as an infrared signal or a Bluetooth signal) sent from the control device 5 (such as a remote controller), the signal receiving unit 233 can decode the received signal to generate a corresponding operation signal.
