It should be noted that FIG. 2 only shows a system architecture diagram of the terminal device in one embodiment, and the system architecture of the terminal device may also be other architectures, which are not limited herein.

As shown in FIG. 3, in one embodiment, an interface display method is provided, which can be applied to the above-mentioned terminal device, and the method may include the following steps:

Step 310, when the first operating system in the terminal device receives the system switching request sent by the second operating system, the first operating system loads the first display module in the first operating system according to the system switching request.

The second operating system may refer to the operating system currently running in the foreground in the terminal device, that is, the operating system to be switched out, wherein the operating system running in the foreground may refer to the one that can directly interact with the user through the screen display interface The user can directly see the interface displayed by the operating system through the screen of the terminal device. The first operating system may refer to an operating system to be switched in. When the second operating system detects the system switching operation, it can trigger the generation of a system switching request, and send the system switching request to the first operating system.

Optionally, the system switching operation may be an operation actively triggered by the user, for example, the user actively switches the operating system, the user clicks to start the application of the first operating system, etc.; the system switching operation may also be performed by the terminal device according to the actual operating conditions. A switching operation that is actively triggered. For example, when an application of the first operating system receives a push message, it can send a notification that triggers the system switching operation to the second operating system, and the second operating system generates a system switching operation according to the notification that triggers the system switching operation. ask.

In some embodiments, when the second operating system is running, the first operating system can be in a dormant state, so that the power consumption of the terminal device can be reduced. When the first operating system receives a system switching request sent by the second operating system, The first operating system may be awakened based on the system switching request, and load the first display module in the first operating system, wherein the sleep state may refer to the fact that the data of the first operating system is stored in the memory, and the first operating system corresponds to Some or all of the processing cores or processors are powered off, and other associated hardware (such as hard disks, etc.) may also be powered off. The first display module may include a display driver in the first operating system, as well as products or services related to screen display, etc. The loading of the first display module by the first operating system may include the first operating system loading the display driver, and The screen displays related products or services, etc. to be loaded, and the display bus controller and screen can be initialized and configured. Only after the first display module is loaded, the display interface rendered in the first operating system can be output to the screen for display.

Step 320: During the process of loading the first display module by the first operating system, the first operating system renders the display interface, and writes the display data of the display interface into the shared display buffer area.

In the related art, the first operating system needs to wait for the first display module to be loaded before rendering the display interface, and control the screen to display through the first display module, and the loading process of the first display module takes a long time. Therefore, it is easy to cause screen freezes and discontinuous display, which makes users mistakenly believe that the terminal device has system freezes, which affects the user's experience of using the terminal device.

In this embodiment of the present application, during the process of loading the first display module, the first operating system may directly render the display interface, and the display interface may be the system interface of the first operating system, or the first operating system startup The main interface of the application, or a preset transition interface for operating system switching, etc., but not limited to this. The first operating system renders the display interface, obtains display data of one or more frames of the display interface, and writes the display data into the shared display buffer area.

The shared display buffer area may be a display buffer area shared between the first operating system and the second operating system. For the shared display buffer area, both the first operating system and the second operating system have access rights, and the first operating system and the second operating system have access rights. Both operating systems can write display data into the shared display buffer area, and can also obtain display data from the shared display buffer area.

In some embodiments, the shared display buffer area may be the same storage area in the terminal device that can be used by the first operating system and the second operating system in common. The shared display buffer area can also be respectively set with a first storage area corresponding to the first operating system and a second storage area corresponding to the second operating system. The first storage area and the second storage area can be separate storage areas, and the An operating system can send display data to the second storage area corresponding to the second operating system through inter-system communication, and the second operating system can also send display data to the first storage area corresponding to the first operating system through inter-system communication area. The communication between the systems can be carried out in many different ways, for example, communication can be carried out using a dual-core communication service, or communication can be carried out through a shared memory bus or the like.

The first operating system can send the display data of the rendered display interface to the shared display buffer area of the second operating system through inter-system communication, and the display data is stored in the shared display buffer area of the second operating system.

Step 330, the second operating system acquires display data from the shared display buffer area, and controls the screen to display the display interface according to the display data.

The second operating system can obtain the display data written by the first operating system from the shared display buffer area, and control the screen to display the corresponding display interface through the second display module in the second operating system. Since the second operating system is always running, the second display module in the second operating system can send display data to the screen for display without being loaded, so that the display interface rendered by the first operating system can be displayed immediately. , to ensure the continuity of the display screen.

If the first operating system continuously writes display data to the shared display buffer area of the second operating system, the second operating system can sequentially obtain the display data from the shared display buffer area, and control the screen to continuously refresh and display the acquired display data corresponding display interface.

FIG. 4 is a schematic diagram of screen display of a terminal device in one embodiment. Exemplarily, as shown in FIG. 4 , the interface 402 is the interface currently displayed by the second operating system, and the interface 404 is the system interface of the first operating system. After the first operating system receives the system switching request sent by the second operating system, in the process of loading the first display module, the interface 404 can be rendered, and the rendered display data of the interface 404 can be written into the second operation The system's shared display buffer. The second operating system may acquire display data of the interface 404 from the shared display buffer, and control the screen display interface 404 according to the display data. It is not necessary to wait until the first display module is loaded by the first operating system, and the screen of the terminal device can display the interface 404, but the second operating system prompts the display interface 404, which can greatly improve the screen that appears when the operating system is switched. In the case of stuck or discontinuous display, the interface display can be continuously and smoothly switched without feeling.

In some embodiments, when the first display module in the first operating system is loaded, the first operating system can stop writing the display data of the rendered display interface into the shared display buffer, and control the display through the first display module. The screen displays the rendered display interface. After the first display module is loaded, the terminal device can switch back to the normal display process of the first operating system, and the first operating system can no longer write display data to the shared display buffer of the second operating system, but directly pass the first operating system The display module sends the display data of the rendered display interface to the screen, and controls the screen to display.

In some embodiments, when the first display module in the first operating system is loaded, the first operating system may send a first message to the second operating system, where the first message may be used to notify the second operating system that the switching is completed. The second operating system may stop acquiring display data from the shared display buffer area according to the first message, and enter a sleep state. After receiving the first message sent by the first operating system, the second operating system can stop acquiring display data from the shared display buffer area and stop controlling the screen to display, and the first operating system can take over the control authority of the screen and restore it. into the normal screen display process of the first operating system.

It should be noted that only the interface display of switching from the second operating system to the first operating system is described in the embodiments of the present application, and the method flow of switching from the first operating system to the second operating system may be the same as that of switching from the second operating system to the second operating system. The process of the method for switching to the first operating system is similar, and details are not repeated here. In addition, a third operating system and a fourth operating system can also be installed in the terminal device, and the switching between any two operating systems can refer to the description of the method for switching from the second operating system to the first operating system. This application implements The example does not limit the specific operating system.

In the embodiment of the present application, when the first operating system in the terminal device receives the system switching request sent by the second operating system, the first operating system loads the first display module in the first operating system according to the system switching request, During the process of loading the first display module by the first operating system, the first operating system renders the display interface and writes the display data of the display interface into the shared display buffer area. A shared display buffer area is established between the two, and when the system is switched, the first operating system to be switched in renders the display interface and writes it into the shared display buffer area, and then the second operating system to be switched out obtains the display from the shared display buffer area. Data and control the screen display, it does not need to wait for the first display module of the first operating system to be loaded before the display interface rendered by the first operating system can be displayed, which can greatly improve the screen freeze or display discontinuity that occurs when the operating system is switched. In other cases, the interface display can be continuously and smoothly switched without feeling.

As shown in FIG. 5, in one embodiment, another interface display method is provided, which can be applied to the above-mentioned terminal device, and the method may include the following steps:

Step 502, when the first operating system in the terminal device receives the system switching request sent by the second operating system, the first operating system wakes up the system service according to the system switching request.

The framework layer of the first operating system may include multiple services, which may include but are not limited to system services, switching services, dual-core communication services, interface services, etc. interface, so that each application can use the system function of the first operating system or the hardware of the terminal device by calling the interface or service. The system service may provide a control interface to the system layer of the first operating system, such as power management service, window management service, etc., but is not limited thereto.

When the terminal device is not running the first operating system, the first operating system can be in a dormant state, and when the first operating system receives a system switching request sent by the second operating system, the first operating system can wake up the system according to the system switching request Serve.

Exemplarily, taking the Android operating system as the first operating system as an example, when the Android operating system receives a system switching request sent by other operating systems, a wakelock can be created to pair AMS (Activity Manager Service, activity management service), WMS (Window Manager Service, window management service) and/or PMW (Power Manage Service, power management service) and other system services to wake up, the wakelock is a lock mechanism in the Android operating system, as long as the wakelock is held, the Android operating system cannot Enter sleep state.

Step 504, the first operating system sends a loading instruction to the interface service through the system service.

After the system service of the first operating system is awakened, the system service can communicate with the interface service, and send a loading instruction to the interface service. The interface service can be used to implement functions such as interface establishment, control and management. The loading instruction can be used The interface service is instructed to load the first display module.

Step 506, after receiving the loading instruction, the interface service immediately returns a preparation instruction to the system service, and loads the first display module according to the loading instruction, and the preparation instruction is used to instruct the system service to render the display interface.

After the interface service receives the loading command, since the loading of the first display module takes a long time, the interface service can immediately return a preparation command to the system service, and the preparation command can be used to inform the system service that the first display module is "ready", After the interface service sends the preparation instruction, the loading of the first display module can be continued abnormally. After the system service receives the preparation instruction returned by the interface service, the first operating system can normally start to request rendering of the display interface.

Exemplarily, taking the Android operating system as the first operating system as an example, after the system services such as AMS, WMS, and PMW of the Android operating system are awakened, SurfaceFlinger can be called through SurfaceFlinger.setDisplayPowerMode, so that SurfaceFlinger loads the first display module. The SurfaceFlinger is an interface service in the Android operating system, which can be used to control the interface display.

Step 508 , the first operating system sends a message of starting the shared display buffer to the interface service through the switching service, where the message of starting the shared display buffer is used to instruct the interface service to write the display data of the rendered display interface into the shared display buffer.

The handover service in the first operating system may be used to control the handover function between systems. After the interface service returns the preparation instruction and the first operating system starts to render the display interface, the switching service may send a message to start the shared display buffer area to the interface service. After receiving the message to start the shared display buffer area, the interface service can The start shared display buffer message writes the display data of the rendered display interface into the shared display buffer of the second operating system. Further, the interface service can be sent to the second operating system through the dual-core communication service, and written into the shared display buffer area of the second operating system.

While the interface service controls the rendered display data, the interface service is also loading the first display module. The interface service can create two threads to perform different tasks in the interface service, and load the first display through the first thread. The module sends the display data to the shared display buffer area of the second operating system through the second thread, and the dual-thread working mode will not affect each other, and can ensure that the two are performed at the same time, thereby improving the work efficiency of the interface service.

In some embodiments, the step of writing the display data of the display interface into the shared display buffer area may include: when the first operating system receives the second message sent by the second operating system, displaying the display interface according to the second message The data is written into the shared display buffer, and the second message is used to indicate that the second operating system has enabled the shared display buffer.

After the second operating system sends a system switching request to the first operating system and receives a confirmation message replied by the first operating system, the second operating system can prepare to enable the shared display buffer area to refresh the screen. The second operating system can send the second message to the first operating system through the dual-core communication service. After receiving the second message, the first operating system determines that the second operating system has completed the switching preparation, and sends the second operating system to the interface service through the switching service. The shared display buffer area message is started, and the interface service writes the display data of the display interface into the shared display buffer area of the second operating system. The first operating system writes display data to the shared display buffer area only after receiving the second message indicating that the second operating system has enabled the shared display buffer area, which can ensure that the second operating system can normally and accurately access the shared display buffer area. The display data is read in the buffer area and the screen is controlled to be displayed, which further ensures the fluency of the screen display.

Step 510, the second operating system acquires display data from the shared display buffer, and controls the screen to display the display interface according to the display data.

For step 510, reference may be made to the relevant description of step 330 in the foregoing embodiment, and details are not described herein again.

In some embodiments, after the second operating system sends a system switching request to the first operating system, the screen may be controlled to display an initial transition screen according to the stored interface resources. Optionally, the stored interface resources may be a system switching process. The display interface shown in the first frame in . After the second operating system waits for the first time period, the display data written by the first operating system can be obtained from the shared display buffer area, and the screen display interface can be controlled according to the display data. The first duration can be set according to actual needs, such as 30 milliseconds or 20 milliseconds, thereby reducing the time for the second operating system to wait for the first operating system to render and write the display data of the first frame of the display interface, and to better realize the picture Continuous and senseless switching. In addition, the second operating system only stores the interface resources of the initial transition screen, and does not occupy too much storage space of the second operating system, thereby ensuring the system performance of the second operating system.

Step 512, when the first display module is loaded, the first operating system sends a stop sharing display buffer message to the interface service through the switching service, and the stop sharing display buffer message is used to instruct the interface service to stop displaying the display interface to be rendered. The data is written into the shared display buffer area, and the rendered display interface is displayed on the screen controlled by the first display module.

When the loading of the first display module in the first operating system is completed, the first operating system may stop writing the display data of the rendered display interface into the shared display buffer area. In some embodiments, after monitoring that the first display module has been loaded, the switching service in the first operating system may send a stop sharing display buffer message to the interface service. After receiving the stop sharing display buffer message, the interface service can stop writing the display data of the rendered display interface into the shared display buffer based on the stop sharing display buffer message, and restore the normal display process. The interface service can The rendered display interface is displayed on the screen controlled by the first display module.

Optionally, the switching service of the first operating system can also send a first message to the second operating system through the dual-core communication service, indicating that the first display module has been loaded, and the second operating system can stop the display from the shared display according to the first message. The display data is obtained from the buffer area, and it enters the sleep state.

In the embodiment of the present application, the interface display during the system switching process is controlled by the mutual cooperation of multiple services in the first operating system and the second operating system, so that when the system is switched, the second operating system can control the first operating system in advance The display interface rendered by the operating system is displayed, and the display interface rendered by the first operating system can be displayed without waiting for the first display module of the first operating system to be loaded, which can greatly improve the screen freeze or freeze when switching the operating system. Display discontinuous and other situations, realize continuous and smooth non-inductive switching of interface display.

As shown in FIG. 6, in one embodiment, another interface display method is provided, and the method can be applied to the above-mentioned terminal device, and the method can include the following steps:

Step 602, when the second operating system detects an application startup operation for the target application, in response to the application startup operation, sends a system switching request to the first operating system, where the system switching request includes the application identifier of the target application.

When the terminal device runs the second operating system, the interface of the second operating system may display application icons of one or more target applications, and the target applications may refer to applications that need to be run by the first operating system, for example, the first operating system. If an operating system is an operating system with rich functions but high power consumption, the target application may be an application requiring complex functions, such as a game application or a video application; the target application may also be an application installed in the first operating system. The user can trigger the startup of the target application in the interface of the second operating system, and when the second operating system detects an application startup operation for the target application, it can generate a system switching request according to the application identifier of the target application, and send it to the first operation system. The system sends the system switching request. The system switching request may be used to request the first operating system to start the target application, and the application identifier may include but not limited to information such as the application number, the package name of the application, and the version number of the application.

Step 604, the first operating system starts and loads the target application according to the application identifier in the system switching request, and synchronously loads the first display module in the first operating system.

After the first operating system receives the system switching request, it can parse the system switching request to obtain the application identifier of the target application, start and load the target application according to the application identifier, and simultaneously load the first display in the first operating system. module. In some embodiments, after the first operating system wakes up the system service according to the system switching request, the system service can create an active process, start and load the target application in the active process, and simultaneously load the first display module through the interface service.
