Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
With the increasing demand of users on application experience, the requirements on various performance indexes of an operating system in the intelligent device are increased, and the setting of the dual system on the intelligent device becomes possible. When the intelligent device configured with the dual systems performs system switching, the content displayed on the display interface of the intelligent device is often switched along with the system switching, which may affect the experience of some users with specific data viewing requirements.
The inventor finds that if a system in a running state is switched from a first system to a second system, picture data corresponding to the first system can be acquired, and then the picture data is sent to the second system, so that the second system displays the picture data. Compared with the problem that the user cannot continuously check specific data due to the fact that the equipment pictures are switched with the system after the system is switched in the related technology, the method achieves the effect that the picture data of the equipment are displayed to be consistent before and after the system is switched, convenience is provided for the user to check the data, and user experience is improved.
Therefore, in order to improve the above problem, the inventor proposes a picture display method, a device, an electronic device, and a storage medium, which are provided by the present application, and can make picture data of devices displayed to be consistent before and after system switching, thereby providing convenience for a user to view data and improving user experience.
The electronic device in the embodiment of the present application may be a mobile phone, a smart watch, a tablet computer, a notebook computer, a palm computer, a wearable device (e.g., a smart watch), a Virtual Reality (VR) device, an Augmented Reality (AR) device, a wireless terminal in industrial control, a wireless terminal in unmanned driving, a wireless terminal in smart home, and the like, and the specific device type may not be limited.
Embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Referring to fig. 1, a flowchart of a screen display method according to an embodiment of the present application is shown. The present embodiment provides a screen display method, which can be applied to the apparatus 400 shown in fig. 8 and an electronic device configured with the apparatus 400, where the electronic device at least includes a first system and a second system. In the embodiment of the application, the power consumption of the first system is higher than that of the second system. The first system and the second system are respectively configured with applications with different functions, and the first system and the second system interact with each other to complete the functions of the electronic equipment. The first system and the second system share a display device (i.e., share a display device). It should be noted that, in this embodiment, the first system and the second system may be executed by the same processor, and the method includes:
step S110: and if the system in the running state is switched from the first system to the second system, acquiring the picture data corresponding to the first system.
A system in an operational state is understood to be a system responsible for data processing, wherein data processing may include processing at least one of data of an application and data of a sensor.
As an implementation manner, when the duration of the screen of the electronic device in the screen-off state reaches a preset duration, system switching may be triggered. For example, a system in operation may be triggered to switch from a first system to a second system. The preset time period may not be limited, and may be, for example, 10 seconds, 15 seconds, 20 seconds, or 30 seconds.
In some embodiments, the duration of the electronic screen being in the screen-off state may be detected in real time, and when the duration of the screen being in the screen-off state of the electronic device is detected to reach a preset duration, the system in the running state may be triggered to be switched from the first system to the second system.
In other embodiments, when it is detected that the duration of the screen of the electronic device being in the screen-off state reaches the preset duration, and the screen state of the electronic device is switched from the screen-off state to the screen-on state, the system in the running state may be triggered to be switched from the first system to the second system.
For example, in some specific embodiments, when it is detected that a duration that a screen of the electronic device is in a screen-off state reaches a preset duration, and it is detected that a user switches a screen state of the electronic device from a screen-off state to a screen-on state by touching a specific function key of the electronic device, the system in the running state is triggered to switch from the first system to the second system. The specific function key may include an on/off key or a Home key of the electronic device.
In other specific embodiments, if it is preset that the screen is triggered to be switched from the off-screen state to the on-screen state when the message notification of the specific application is received, the system in the running state may be triggered to be switched from the first system to the second system when it is detected that the duration that the screen of the electronic device is in the off-screen state reaches the preset duration, and it is detected that the message notification of the specific application is received. The specific application program can comprise an instant communication application program, and the message notification of the specific application program can be a message notification of the instant communication application program, or an incoming call.
As another embodiment, the system switching may be triggered according to the power of the electronic device. For example, when the power of the electronic device is lower than the power threshold, the electronic device may automatically trigger the system currently in the operating state to be switched from the first system to the second system, or an interface of the first system (for example, a system switching setting interface) may be manually operated to trigger the system currently in the operating state to be switched from the first system to the second system. The power consumption of the second system is lower than that of the first system, the power threshold may be preset, and the specific value may not be limited, for example, for an electronic device with a total power of 100%, the power threshold may be 30%, or other values, so that when the power of the electronic device is low, the standby duration or the use duration of the electronic device is prolonged by switching the system in the operating state to the system with relatively low power consumption.
In the embodiment of the present application, the screen data may be screen data of a system main interface, screen data displayed by any application interface, a standby screen, or a screen saver screen. The type of the picture data may be a picture, and the picture may include text, numbers, characters, or images. The screen data corresponding to the first system may be a screen displayed by a main interface of the first system, or a screen displayed by an interface of an application configured in the first system. As an embodiment, when the system in the operating state is the first system, the standby screen (which may be a fixed standby screen or a periodically switched standby screen) of the electronic device may be determined as the screen data corresponding to the first system; or determining the picture displayed by the first system at the previous moment when the first system is switched to the second system in the running system as the picture data corresponding to the first system; or when the system in the running state is the first system, and before the screen state of the electronic device is switched from the bright screen state to the off screen state, the last displayed frame of picture is determined as the picture data corresponding to the first system.
In the related art, most of the operating systems configured for the electronic device are single operating systems, and the image data corresponding to different operating systems are different. Therefore, as a way, in a case that an operating system configured in the electronic device is a dual system, in order to avoid a problem that a user cannot continuously view specific data due to switching of device screen data before and after system switching, when it is detected that a system in an operating state is switched from a first system to a second system, the electronic device may acquire screen data corresponding to the first system, so as to synchronize the screen data to the second system.
In an embodiment, when the system in the running state is the first system, if no operation of the screen of the electronic device by the user is detected within a certain time period (for example, within 30 seconds, a specific time period may not be limited), the screen state of the electronic device may be switched from the on-screen state to the off-screen state. At this time, the electronic device will suspend rendering the image data corresponding to the first system, and in this case, the image data corresponding to the first system may be acquired and stored in the memory of the electronic device. Then, as one way, the picture data corresponding to the first system may be acquired (read) from the memory.
Step S120: and sending the picture data to the second system so that the second system displays the picture data.
As a mode, the acquired image data corresponding to the first system may be stored in a memory of the electronic device, and a data acquisition instruction may be sent to the second system to instruct the second system to acquire the image data corresponding to the first system from the memory and display the image data, so that the image data of the electronic device is displayed in a consistent manner before and after the system is switched, and convenience is provided for a user to view the data.
For example, in a specific application scenario, taking an electronic device as an example of a smart watch, please refer to fig. 2, which shows an example diagram illustrating that screen data of the smart watch is displayed to be consistent before and after the system is switched provided by the embodiment of the present application. The picture shown on the left side of fig. 2 is a picture 10 displayed on a desktop dial of the smart watch when the system currently in the running state is the first system, when the system currently in the running state is switched from the first system to the second system, the processor of the smart watch can send the picture 10 to the second system, and the second system can display the picture 10, so that when the system currently in the running state is the second system, a picture 20 (as shown on the right side of fig. 2) displayed on the desktop dial of the smart watch is the same as the content of the picture 10, so that a user can still view related content after the system is switched, and visual jump caused by picture change due to system switching can be avoided.
In another specific application scenario, please refer to fig. 3, which illustrates an exemplary diagram of a change process of screen data displayed by an electronic device before and after system switching according to an embodiment of the present application. Wherein, when the picture shown at the leftmost of fig. 3 represents that the system in the running state is the first system, the standby picture displayed on the screen of the electronic device changes to the black screen picture shown in the middle of fig. 3 after the first system is in a sleep state or is turned off, and when a user clicks a physical key for turning on the screen or directly clicks the screen (for example, a touch screen), the system in the running state can be triggered to be switched from the first system to the second system, the electronic device sends the standby picture to the second system, and the second system displays the standby picture, so that the picture displayed on the screen of the electronic device after the system in the running state is switched to the second system is still the standby picture (such as the picture shown at the rightmost of fig. 3), thereby realizing that the pictures displayed on the screen of the electronic device before and after the system is switched are consistent, the poor visual experience of the user caused by frequent switching of the pictures is avoided.
Optionally, the acquired image data corresponding to the first system may also be stored locally, and a data acquisition instruction is sent to the second system to instruct the second system to read the image data corresponding to the first system from the local and display the image data.
In the image display method provided in this embodiment, if the system in the running state is switched from the first system to the second system, the image data corresponding to the first system is obtained, and then the image data is sent to the second system, so that the second system displays the image data. Compared with the problem that the user cannot continuously check specific data due to the fact that the equipment pictures can be switched with the system after the system is switched in the related technology, the scheme realizes that the picture data of the equipment are displayed to be consistent before and after the system is switched, convenience is provided for the user to check the data, and user experience is improved.
Referring to fig. 4, a flowchart of a picture displaying method according to another embodiment of the present application is shown, where the present embodiment provides a picture displaying method, which can be applied to an electronic device, where the electronic device at least includes a first processor and a second processor, the first processor is used to operate a first system, and the second processor is used to operate a second system, that is, the first system and the second system in the present embodiment are operated by different processors. The first system and the second system in this embodiment may be configured to execute different functions of the same application. The method comprises the following steps:
step S210: and if the system in the running state is switched from the first system to the second system, the first processor acquires the picture data corresponding to the first system.
In this embodiment, if the system in the running state is switched from the first system to the second system, the first processor may obtain the picture data corresponding to the first system, where the principle and the specific implementation process for obtaining the picture data corresponding to the first system may refer to the description in the foregoing embodiments, and are not described herein again.
Optionally, the first processor in this embodiment may capture a last displayed frame of picture before the screen state of the electronic device is switched from the bright screen state to the off screen state when the system in the running state is switched from the first system to the second system, and use the captured picture as picture data corresponding to the first system.
Optionally, when the first system and the second system are configured with different functions for executing the same application, in order to prevent data confusion, two partial regions may be created in the memory of the electronic device, where the two partial regions respectively correspond to a sub-memory for storing data received by the first processor or data corresponding to the function executed by the first processor and data received by the second processor or data corresponding to the function executed by the second processor. The sub memory for storing the data received by the first processor may be referred to as a first memory, and the first memory corresponds to the first system. The sub-memory for storing data received by the second processor may be referred to as a second memory, and the second memory corresponds to a second system. In this manner, after the first processor acquires the picture data corresponding to the first system, the picture data may be stored in the first memory corresponding to the first system.
In a specific application scenario, it is assumed that an electronic device is configured with an application 1, a first system of the electronic device is configured to execute an a function of the application 1, and a second system of the electronic device is configured to execute a B function of the application 1, where the a function and the B function are different functions. Optionally, the a function and the B function may both be background functions. If the system in the running state is the first system and the first system is executing the function a, the image displayed on the screen of the electronic device is the interface of the function a, and in this case, if the system in the running state is currently switched from the first system to the second system, the first processor may intercept a frame of system interface displayed last by the first system before the system is switched, as image data corresponding to the first system, and store the image data in the first memory. Meanwhile, the first processor may send a content data obtaining instruction to the second processor to instruct the second processor to obtain the picture data from the first memory. The interface of the function A can be displayed on the system interface of the first system in a floating manner.
Step S220: and the first processor sends the picture data to the second processor so that the second processor controls the second system to display the picture data.
Alternatively, the first processor may send the frame data to the second processor via a hardware communication link (e.g., a Serial Peripheral Interface (SPI) bus). After receiving the image data, the second processor may store the image data in a second memory corresponding to the second system, so that when the second system wakes up, the image data may be directly read from the second memory without acquiring the image data from the first memory.
Continuing with the above example as an example, after the second processor acquires the picture data, the picture data may be stored in the second memory, and the second system is controlled to display the picture data, that is, after the system is switched to the second system, when the second system executes the B function of the application 1, the interface of the second system is the same as the interface of the first system (at this time, the interface of the B function is displayed on the system interface of the second system in a floating manner), so that different contents may be displayed to the user while the system interfaces before and after the system switching are kept unchanged, and poor visual experience of the user due to switching of the system interfaces is avoided.
In an embodiment of the present application, the electronic device may include a display controller. Referring to fig. 5, a hardware framework diagram of an electronic device according to an embodiment of the present application is shown. As shown in fig. 5, the electronic device in this embodiment may include a first processor, a second processor, a display controller, and a display device. In this way, in the process of sending the picture data to the second processor, the first processor may stop controlling the display controller (i.e., the first processor and the display controller are still connected, but the first processor no longer controls the display controller), and send a display controller takeover instruction to the second processor, where the display controller takeover instruction is used to instruct the second processor to start controlling the display controller, so that the display controller controls the display device of the electronic device (i.e., the screen of the electronic device) to display the picture data.
In this embodiment, the electronic device may also include at least two display controllers, for example, the electronic device may include at least a first display controller and a second display controller. Referring to fig. 6, a schematic diagram of another hardware framework of an electronic device according to an embodiment of the present application is shown. As shown in fig. 6, the electronic device in this embodiment may include a first processor, a second processor, a first display controller, a second display controller, and a display device. In this way, in the process of sending the picture data to the second processor, the first processor may control to turn off the first display controller (i.e., the first processor cuts off the connection with the first display controller), and notify the second processor to turn on the second display controller, so that the second display controller controls the display device of the electronic device (i.e., the screen of the electronic device) to display the picture data.
It should be noted that, in the embodiment of the present application, an example is given in which the electronic device includes a dual system, and the electronic device may also be configured with more systems in actual implementation, for example, the electronic device may further include a triple system and a multiple system, and the picture display method provided in the embodiment of the present application is applicable to a case where the electronic device includes a triple system or a multiple system, and specifically, before and after the system is switched, an implementation principle and an implementation process for displaying picture data of the device to be consistent are not described herein again.
In this embodiment, the electronic device may include three or more processors in addition to the first processor and the second processor, in which different processors are used to run different systems, and power consumptions corresponding to the different processors are different. When the currently running system is switched from a system with relatively high power consumption to a system with relatively low power consumption, the picture data of the equipment can be displayed to be consistent before and after the system is switched, and convenience is provided for a user to check the data.
In the image display method provided in this embodiment, if the system in the running state is switched from the first system to the second system, the first processor acquires the image data corresponding to the first system, and then sends the image data to the second processor, so that the second processor controls the second system to display the image data. Compared with the problem that the user cannot continuously check specific data due to the fact that the equipment pictures can be switched with the system after the system is switched in the related technology, the scheme realizes that the picture data of the equipment are displayed to be consistent before and after the system is switched, convenience is provided for the user to check the data, and user experience is improved.
Referring to fig. 7, a flowchart of a picture displaying method according to another embodiment of the present application is shown, where the present embodiment provides a picture displaying method, which can be applied to an electronic device, where the electronic device at least includes a first processor and a second processor, the first processor is used to run a first system, and the second processor is used to run a second system, that is, the first system and the second system in the present embodiment are run by different processors. The method comprises the following steps:
step S310: and the second processor receives picture data corresponding to the first system, wherein the picture data is obtained by the first processor if the system in the running state is switched from the first system to the second system.
Step S320: and the second processor controls the second system to display the picture data.
In the embodiment of the present application, the electronic device may include a display controller (as shown in fig. 5 described above). In this manner, the second processor may start controlling the display controller in response to the display controller takeover instruction sent by the first processor, so that the display controller controls the display device of the electronic apparatus (i.e., the screen of the electronic apparatus) to display the picture data.
In the embodiment of the present application, the electronic device may also include at least two display controllers, for example, as shown in fig. 6, the electronic device may include at least a first display controller and a second display controller. In this manner, the second processor may start the second display controller in response to a display controller takeover instruction sent by the first processor, so that the second display controller controls the display device of the electronic device (i.e., the screen of the electronic device) to display the picture data, where the display controller takeover instruction is used to instruct the second processor to start the second display controller.
In the image display method provided in this embodiment, the second processor receives the image data corresponding to the first system, where the image data is obtained by the first processor if the system in the running state is switched from the first system to the second system, and then the second processor controls the second system to display the image data. The display method and the display device have the advantages that the display of the picture data of the equipment is consistent before and after the system is switched, convenience is provided for a user to check the data, and the user experience is improved.
