As shown in fig. 2, the terminal device may be installed with an operating system a and an operating system B, where the operating system a may include an application layer, a framework layer, a kernel layer, and the like. Wherein the application layer may be installed with one or more application programs.

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 is not limited herein.

As shown in fig. 3, in an embodiment, an interface display method is provided, which is applicable to the terminal device described above, and the method may include the following steps:

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

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

Optionally, the system switching operation may be an operation actively triggered by a user, for example, the user actively switches the operating system, the user clicks and starts an application of the first operating system, and the like; the system switching operation may also be a switching operation actively triggered by the terminal device according to an actual operating condition, for example, when the application of the first operating system receives the push message, a notification triggering the system switching operation may be sent to the second operating system, and the second operating system generates a system switching request according to the notification triggering the system switching operation.

In some embodiments, when the second operating system runs, the first operating system may be in a sleep state, so as to reduce power consumption of the terminal device, and when the first operating system receives a system switching request sent by the second operating system, the first operating system may be woken up based on the system switching request and load the first display module in the first operating system, where the sleep state may refer to that data of the first operating system is stored in the memory, a part or all of a processing core or a processor corresponding to the first operating system is powered off, and other associated hardware (e.g., a hard disk and the like) may also be in a powered off state. The first display module may include a display driver in the first operating system, and a product or service related to the screen display, and the loading of the first display module by the first operating system may include loading of the display driver, the product or service related to the screen display, and the like by the first operating system, and may initialize and configure the display bus controller, the screen, and the like. And only after the first display module is loaded, the display interface rendered in the first operating system can be output to a screen for displaying.

Step 320, in 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 cache region.

In the related technology, the first operating system renders the display interface after waiting for the first display module to be loaded, and displays the display interface through the first display module control screen, and because the loading process of the first display module consumes a long time, the situations of screen blocking, display discontinuity and the like easily occur, so that a user mistakenly thinks that the terminal equipment is blocked by the system, and the experience of the user in using the terminal equipment is influenced.

In this embodiment of the application, the first operating system may directly render a display interface in a process of loading the first display module, where the display interface may be a system interface of the first operating system, a main interface of an application started by the first operating system, or a transition interface switched by a preset operating system, but is not limited thereto. The first operating system renders the display interface, can obtain the display data of one or more frames of display interfaces, and writes the display data into the shared display cache area.

The shared display cache region may be a display cache region shared between the first operating system and the second operating system, and both the first operating system and the second operating system have access rights for the shared display cache region, and both the first operating system and the second operating system may write display data into the shared display cache region or may obtain the display data from the shared display cache region.

In some embodiments, the shared display buffer may be the same block of memory area in the terminal device that is commonly used by the first operating system and the second operating system. The shared display cache region may also be separately provided with a first storage region corresponding to the first operating system and a second storage region corresponding to the second operating system, the first storage region and the second storage region may be separate storage regions, the first operating system may send display data to the second storage region corresponding to the second operating system through an inter-system communication method, and the second operating system may also send display data to the first storage region corresponding to the first operating system through an inter-system communication method. The communication mode between the systems may be different, for example, the dual core communication service may be used for communication, or the communication may be performed through a shared memory bus.

The first operating system can send the rendered display data of the display interface to a shared display cache region of the second operating system in an intersystem communication mode, and the shared display cache region of the second operating system stores the display data.

And step 330, the second operating system acquires display data from the shared display cache region and controls a screen to display a display interface according to the display data.

The second operating system can acquire the display data written by the first operating system from the shared display cache region, and controls the screen to display a corresponding display interface through a second display module in the second operating system. Because the second operating system is always in the running state, the second display module in the second operating system can send the display data to the screen for displaying without loading, so that the effect of displaying the display interface rendered by the first operating system immediately can be realized, and the continuity of the display image is ensured.

If the first operating system continuously writes the display data into the shared display cache region of the second operating system, the second operating system can sequentially acquire the display data from the shared display cache region, and control the screen to continuously refresh and display the display interface corresponding to the acquired display data.

Fig. 4 is a schematic screen display diagram of a terminal device in one embodiment. Illustratively, as shown in FIG. 4, interface 402 is the interface currently displayed by the second operating system, and interface 404 is the system interface of the first operating system. After the first operating system receives a system switching request sent by the second operating system, in the process of loading the first display module, the interface 404 may be rendered, and display data of the rendered interface 404 may be written into the shared display cache area of the second operating system. The second operating system may obtain display data for the interface 404 from the shared display cache and control the on-screen display interface 404 according to the display data. The screen of the terminal device can display the interface 404 without waiting for the first display module to be loaded by the first operating system, but the second operating system prompts the display of the interface 404, so that the situations of picture blockage or display discontinuity and the like during the switching of the operating systems can be greatly improved, and the continuous and smooth non-inductive switching of interface display is realized.

In some embodiments, 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, and control the screen to display the rendered display interface through the first display module. After the first display module is loaded, the terminal device can switch back to the normal display flow of the first operating system, the first operating system can not write display data into the shared display cache region of the second operating system any longer, but directly sends the rendered display data of the display interface to the screen through the first display module, and controls the screen to display.

In some embodiments, when the loading of the first display module in the first operating system is complete, the first operating system may send a first message to the second operating system, which may be used to notify the second operating system that the switch is complete. The second operating system can stop obtaining the display data from the shared display cache according to the first message and enter a dormant state. And after receiving the first message sent by the first operating system, the second operating system can stop obtaining the display data from the shared display buffer area, stop controlling the screen to display, take over the control authority of the screen by the first operating system and restore the control authority to the normal screen display flow of the first operating system.

It should be noted that, in the embodiment of the present application, only the interface display that is switched from the second operating system to the first operating system is described, and a method flow for switching from the first operating system to the second operating system may be similar to a method flow for switching from the second operating system to the first operating system, and is not repeated here. In addition, a third operating system and a fourth operating system may also be installed in the terminal device, and switching between any two operating systems may be described with reference to a method flow for switching from the second operating system to the first operating system.

In the embodiment of the application, when a first operating system in a terminal device receives a system switching request sent by a second operating system, the first operating system loads a first display module in the first operating system according to the system switching request, the first operating system renders a display interface and writes display data of the display interface into a shared display cache region in the process of loading the first display module by the first operating system, the first operating system renders the display interface to be switched in and writes the display interface into the shared display cache region by establishing the shared display cache region between the first operating system and the second operating system, and then the switched-out second operating system obtains the display data from the shared display cache region and controls a screen to display the display data, 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, the switching method can greatly improve the situations of screen jam or display discontinuity and the like when the operating system is switched, and realize the non-inductive switching of continuous and smooth interface display.

As shown in fig. 5, in an embodiment, another interface display method is provided, which is applicable to the terminal device described above, and the method may include the following steps:

step 502, when a first operating system in the terminal device receives a system switching request sent by a 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 a plurality of services, which may include, but are not limited to, a system service, a switching service, a dual-core communication service, an interface service, and the like, and each service may provide various interfaces for applications of the application layer, so that each application can use system functions of the first operating system or hardware of the terminal device by calling the interfaces or services. The system service may provide a control interface to a system layer of the first operating system, such as, but not limited to, a power management service, a window management service, and the like.

When the terminal device does not run 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 service according to the system switching request.

For example, taking the first operating system as an Android operating system as an example, when the Android operating system receives a system switching request sent by another operating system, a wakelock may be created to wake up system services such as AMS (Activity Manager Service), WMS (Window Manager Service), and/or PMW (Power Manager Service), where the wakelock is a lock mechanism in the Android operating system, and the Android operating system cannot enter a sleep state as long as the wakelock is held.

At step 504, the first operating system sends a load 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 for achieving functions of establishing, controlling, managing and the like of an interface, and the loading instruction can be used for indicating the interface service to load the first display module.

Step 506, after the interface service receives the loading instruction, immediately returning a preparation instruction to the system service, and loading the first display module according to the loading instruction, where the preparation instruction is used for instructing the system service to render the display interface.

After the interface service receives the loading instruction, because the loading time of the first display module is long, the interface service can immediately return a preparation instruction to the system service, the preparation instruction can be used for informing the system service that the first display module is ready, and after the interface service sends the preparation instruction, the first display module can be abnormally and continuously loaded. After the system service receives a preparation instruction returned by the interface service, the first operating system can normally start to request for rendering the display interface.

For example, taking the first operating system as an Android operating system, after system services of the Android operating system, such as AMS, WMS, and PMW, are woken up, the surfefinger may be called through the surfflunger setdisplaypower mode, so that the surfefinger loads the first display module. The surfaceFlinger is an interface service in the Android operating system and can be used for controlling interface display.

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

A handoff service in the first operating system may be used to control handoff functions between systems. After the interface service returns the preparation instruction and the first operating system starts to render the display interface, the switching service can send a message for starting the shared display cache region to the interface service, and after the interface service receives the message for starting the shared display cache region, the interface service can write the rendered display data of the display interface into the shared display cache region of the second operating system according to the message for starting the shared display cache region. Further, the interface service may be sent to the second operating system via the dual core communication service, and written to the shared display cache in the second operating system.

The interface service controls rendered display data and loads the first display module, the interface service can respectively establish two threads to execute different tasks in the interface service, the first display module is loaded through the first thread, the display data are sent to a shared display cache region of a second operating system through the second thread, the working modes of the two threads cannot be influenced mutually, the two threads can be guaranteed to be carried out simultaneously, and the working efficiency of the interface service is improved.

In some embodiments, the step of writing the display data of the display interface into the shared display buffer may include: when the first operating system receives a second message sent by the second operating system, the display data of the display interface is written into the shared display cache region according to the second message, and the second message is used for representing that the second operating system enables the shared display cache region.

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 may prepare to enable the shared display cache region to refresh the screen. The second operating system can send a second message to the first operating system through the dual-core communication service, the first operating system determines that the second operating system finishes the switching preparation after receiving the second message, sends a message of starting the shared display cache region to the interface service through the switching service, and the interface service writes the display data of the display interface into the shared display cache region of the second operating system. The first operating system writes the display data into the shared display cache region after receiving a second message indicating that the second operating system has enabled the shared display cache region, so that the second operating system can normally and accurately read the display data from the shared display cache region and control a screen to display, and further the fluency of image display is ensured.

And step 510, the second operating system acquires display data from the shared display cache region and controls a screen to display a display interface according to the display data.

Step 510 may refer to the related description of step 330 in the above embodiments, and is not described herein again.

In some embodiments, after the second operating system sends the system switching request to the first operating system, the initial transition picture may be displayed according to the stored interface resource control screen, and optionally, the interface resource according to the storage may be a display interface displayed in a first frame in the system switching process. After waiting for the first time period, the second operating system can acquire the display data written by the first operating system from the shared display cache region, and control the screen to display the display interface according to the display data. The first duration can be set according to actual requirements, for example, 30 milliseconds and 20 milliseconds, so that 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 display interface can be reduced, and the continuous and non-inductive switching of the picture can be better realized. And the second operating system only stores the interface resources of the initial transition picture, so that the storage space of the second operating system is not occupied too much, and the system performance of the second operating system is ensured.

Step 512, when the first display module is loaded, sending, by the switching service, a message of stopping the shared display buffer area to the interface service in the first operating system, where the message of stopping the shared display buffer area is used to instruct the interface service to stop writing the display data of the rendered display interface into the shared display buffer area, and displaying the rendered display interface through the first display module control screen.

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 cache region. In some embodiments, the switching service in the first operating system may send a stop sharing display buffer message to the interface service after monitoring that the first display module has been loaded. After receiving the message of stopping the shared display buffer area, the interface service can stop writing the display data of the rendered display interface into the shared display buffer area according to the message of stopping the shared display buffer area and recover to a normal display flow, and the interface service can control the screen to display the rendered display interface through the first display module.

Optionally, the switching service of the first operating system may further send a first message to the second operating system through the dual-core communication service, indicating that the first display module is loaded, and the second operating system may stop acquiring the display data from the shared display cache according to the first message and enter the hibernation state.

In the embodiment of the application, the interface display in the system switching process is controlled by the cooperation of a plurality of services in the first operating system and the second operating system, so that the display interface rendered by the first operating system is displayed by the second operating system in advance when the systems are switched, the display interface rendered by the first operating system can be displayed without waiting for the completion of the loading of the first display module of the first operating system, the situations of picture blocking or discontinuous display and the like during the switching of the operating systems can be greatly improved, and the continuous and smooth non-inductive switching of the interface display is realized.

As shown in fig. 6, in an embodiment, another interface display method is provided, which is applicable to the terminal device described above, and the method may include the following steps:

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

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

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.
