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 equipment are increased, and the setting of a dual system on the intelligent equipment is possible. When the intelligent device configured with the dual systems switches systems, the display characteristics (such as screen brightness and the like) of the intelligent device are often switched along with the systems, and the visual experience of the user is influenced to a certain extent.
The inventor finds that if a system in a running state is switched from a first system to a second system, a brightness parameter corresponding to the first system is obtained, and then the brightness parameter is sent to the second system, so that a screen of the electronic device controlled by the second system is displayed according to the brightness parameter. Compared with the problem that the display characteristics of the equipment can be switched along with the switching of the system in the related art to influence the visual experience of the user, the mode realizes that the screen brightness of the equipment is displayed to be consistent before and after the system is switched, and the visual experience of the user is improved.
Therefore, in order to improve the above problem, the inventor proposes a display method, an apparatus, an electronic device, and a storage medium, which are provided by the present application, and can make the screen brightness of the device be displayed consistently before and after the system is switched, thereby improving the visual experience of the user. 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 display method according to an embodiment of the present application is shown. The present embodiment provides a display method, which is applicable to the display device 700 shown in fig. 11 and an electronic apparatus equipped with the display device 700, where the electronic apparatus includes at least a first system and a second system, and power consumption of the first system is higher than power consumption of the second system. It should be noted that, in this embodiment, the first system and the second system are run by the same processor, 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 functions of the electronic device. 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 brightness parameter 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 may include an instant messaging application, and the message notification of the specific application may be a message notification of the instant messaging application, or an incoming call, etc.
In the embodiment of the application, the brightness parameter represents the current brightness value of the screen of the electronic device. As a manner, in order to prevent a screen of the electronic device from generating a brightness jump before and after the system switching, when the system in the operating state is switched from the first system to the second system, the electronic device may acquire a brightness parameter corresponding to the first system, so as to synchronize the brightness parameter to the second system.
Step S120: and sending the brightness parameter to the second system so that the second system controls the screen of the electronic equipment to display according to the brightness parameter.
As a mode, the acquired brightness parameter of the first system may be stored in a memory of the electronic device, and a data acquisition instruction is sent to the second system to instruct the second system to acquire the brightness parameter of the first system from the memory, and control the screen of the electronic device to display according to the brightness parameter, so that the display brightness of the screen of the electronic device is unchanged before and after the system is switched.
For example, in a specific application scenario, as shown in fig. 2, a diagram illustrating a luminance display example of a screen before and after switching by the system provided by the embodiment is shown. Fig. 2 shows a left frame corresponding to the first system with a luminance value of r, and fig. 2 shows a right frame corresponding to the second system. When the system in the operating state is switched from the first system shown in fig. 2 to the second system shown in fig. 2, the brightness value of the picture corresponding to the second system may be the same as the brightness value of the picture corresponding to the first system, that is, the brightness value of the picture corresponding to the second system is also r, and the content of the picture corresponding to the second system may be the same as or different from the content of the picture corresponding to the first system.
Optionally, the acquired brightness parameter of 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 brightness parameter of the first system from the local, and control the screen of the electronic device to display according to the brightness parameter.
In the display method provided in this embodiment, if the system in the operating state is switched from the first system to the second system, the brightness parameter corresponding to the first system is obtained, and then the brightness parameter is sent to the second system, so that the second system controls the screen of the electronic device to display according to the brightness parameter. Compared with the problem that the display characteristics of the equipment are also switched along with the switching of the system in the related art to influence the visual experience of the user, the scheme enables the screen brightness of the electronic equipment when the second system is in the running state to be consistent with the screen brightness of the electronic equipment when the first system is in the running state, and therefore the system switching can be completed under the condition that the sight of the user is not perceived, and the visual experience of the user is improved.
Referring to fig. 3, a flowchart of a display method according to another embodiment of the present application is shown, where the display method is provided in this embodiment and can be applied to an electronic device, where the electronic device at least includes a first system and a second system, and the first system and the second system in this embodiment are run by a same processor. 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, acquiring the brightness parameter corresponding to the first system.
Step S220: and sending the brightness parameter to the second system so that the second system controls the screen of the electronic equipment to display according to the brightness parameter.
Step S230: and acquiring the picture data corresponding to the first system.
In the embodiment of the application, in order to avoid influence on the visual experience of the user due to the fact that the display frames of the electronic device are switched before and after the system is switched, the electronic device may acquire the frame data corresponding to the first system. When the system in the operating state is the first system, a 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 when the system in the operating state is the first system, a last frame of screen displayed before the screen state of the electronic device is switched from the on-screen state to the off-screen state may be determined as the screen data corresponding to the first system, and a specific type of the screen data corresponding to the first system may not be limited.
When the system in the running state is the first system, if the operation of the user on the screen of the electronic device is not detected within a certain time period (for example, within 30 seconds, the specific time value 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 processor may still perform data interaction with the first system, and the display controller of the electronic device suspends rendering the image data corresponding to the first system. Thus, as one way, the frame data corresponding to the first system can be obtained (read) from the memory.
As one mode, if it is detected that the system in the running state is switched from the first system to the second system, the picture data corresponding to the first system may be acquired.
Step S240: and comparing the picture data with the appointed picture data synchronized to the second system last time to obtain difference image data.
In this embodiment, the electronic device may synchronize the screen data corresponding to the first system to the second system multiple times, for example, the screen data synchronized to the second system by the electronic device before and after power failure may be different, and the electronic device may synchronize the history of the screen data synchronized to the second system and store the screen data.
The difference image data represents a difference portion between the currently acquired picture data corresponding to the first system and the picture data synchronized to the second system last time, and the difference portion may specifically include a set of coordinates, where color values (for example, RGB values) of the currently acquired picture data corresponding to the first system and the picture data synchronized to the second system last time are different. The designated picture data characterizes picture data last synchronized by the first system to the second system.
The currently acquired picture data corresponding to the first system and the picture data synchronized to the second system last time are both composed of a plurality of pixel points, and for the position of the same pixel point coordinate, the RGB value of the picture data corresponding to the first system and the RGB value of the picture data synchronized to the second system last time can be different. Therefore, as one mode, the RGB value of the currently acquired image data corresponding to the first system may be compared with the RGB value of the corresponding coordinate position in the designated image data synchronized to the second system at the last time, to obtain position coordinates with different RGB values in the two image data, where the number of the position coordinates may be one or more, and a coordinate set formed by the position coordinates with different RGB values in the two image data is used as the difference image data.
Step S250: and sending the differential image data to the second system so that the second system updates the specified picture data according to the differential image data and displays the updated picture data.
As a mode, in order to reduce the data transmission quantity, the difference image data may be directly sent to the second system, without sending the whole picture data corresponding to the first system to the second system, so that the second system may update the content of the specified picture data according to the difference image data, and display the updated picture data, and at the same time, the data transmission quantity may be reduced, and the network transmission bandwidth may be saved.
In a specific application scenario, as shown in fig. 4, an exemplary diagram of picture data displayed on a screen before and after system switching provided by the present embodiment is shown. When the leftmost system of fig. 4 represents that the system in the running state is the first system, the standby screen displayed by the screen of the electronic device is switched to the black screen in the middle of fig. 4 after the first system is in a dormant state or is turned off, and when the user clicks a physical key for opening the screen or directly clicks the screen, the system in the running state is switched from the first system to the second system, and the screen displayed by the screen of the electronic device is still the standby screen, so that the screens displayed by the screens of the electronic devices before and after the system is switched are consistent, and the generation of bad visual experience of the user due to frequent switching of the screens is avoided.
The display method provided by the embodiment realizes that the screen brightness of the equipment is displayed to be consistent before and after the system is switched, and improves the visual experience of a user. And sending differential image data obtained by comparing the picture data corresponding to the first system with the specified picture data synchronized to the second system last time to the second system, updating the specified picture data according to the differential image data by the second system, and displaying the updated picture data. The pictures displayed on the screens of the electronic equipment before and after the system is switched are consistent, and poor visual experience of a user caused by frequent switching of the pictures is avoided; meanwhile, the data transmission quantity is reduced, and the network transmission bandwidth is saved.
Referring to fig. 5, a flowchart of a display method according to another embodiment of the present application is shown, where the present embodiment provides a display method applicable 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 if the system in the running state is switched from the first system to the second system, the first processor acquires the brightness parameter 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 brightness parameter corresponding to the first system, where the principle and the specific implementation process for obtaining the brightness parameter corresponding to the first system may refer to the description in the foregoing embodiment, and are not described herein again.
Step S320: and the first processor sends the brightness parameter to the second processor, so that the second processor controls the screen of the electronic equipment to display according to the brightness parameter.
Alternatively, the first processor may send the brightness parameter to the second processor via a hardware communication link, such as a Serial Peripheral Interface (SPI) bus.
Optionally, in order to reduce performance loss of obtaining data in the system switching process, a partial area of the memory of the electronic device may be opened up as a sub memory for storing data received by the second processor, so that the second processor may directly retrieve the required data from the sub memory, and after the first processor sends a data obtaining instruction to the second processor, the second processor obtains the data from the memory of the electronic device. The second processor may store the brightness parameter in the sub-memory after receiving the brightness parameter, so that when the system switching is completed, the second processor may read the brightness parameter value from the sub-memory and control the screen of the electronic device to display according to the brightness parameter value, thereby enabling the brightness display of the screen of the electronic device to be consistent before and after the system switching.
In this embodiment, the electronic device may include one display controller. Referring to fig. 6, a hardware framework diagram 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 mode may include a first processor, a second processor, a display controller, and a display device. In this way, in the process of sending the brightness parameter 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 according to the brightness parameter received by the second processor.
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. 7, 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. 7, 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 brightness parameter to the second processor, the first processor may control to turn off the first display controller (that is, 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 (that is, the screen of the electronic device) to display according to the brightness parameter received by the second processor.
In the 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 obtains the brightness parameter corresponding to the first system, and then sends the brightness parameter to the second processor, so that the second processor controls the screen of the electronic device to display according to the brightness parameter. Compared with the problem that the display characteristics of the equipment can be switched with the system after the system is switched in the related technology, so that the visual experience of a user is influenced, the screen brightness of the equipment is displayed to be consistent before and after the system is switched, and the visual experience of the user is improved.
Referring to fig. 8, a flowchart of a display method according to still another embodiment of the present application is shown, where the present embodiment provides a display method applicable 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, and the method includes:
step S410: and if the system in the running state is switched from the first system to the second system, the first processor acquires the brightness parameter corresponding to the first system.
Step S420: and the first processor sends the brightness parameter to the second processor, so that the second processor controls the screen of the electronic equipment to display according to the brightness parameter.
Step S430: and the first processor acquires the picture data corresponding to the first system.
Optionally, two partial areas may be opened up from the memory of the electronic device, and the two partial areas are respectively used for storing the data received by the first processor and the data received by the second processor. The sub memory for storing the data received by the first processor may be referred to as a first memory, the first memory corresponds to the first system, the sub memory for storing the data received by the second processor may be referred to as a second memory, and the second memory corresponds to the second system. In this way, 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, so that when the picture data synchronized to the second system at the next time is different, the picture data synchronized to the second system in history may be directly acquired from the first memory.
Step S440: and the first processor compares the picture data with the appointed picture data synchronized to the second system last time to obtain difference image data.
Step S450: and the first processor sends the difference image data to the second processor, so that the second processor updates the specified picture data according to the difference image data and displays the updated picture data.
Alternatively, the first processor may transmit the difference image data to the second processor through a hardware communication link. After receiving the difference image data, the second processor can directly update the content of the appointed image data synchronized by the first system last time by using the difference image data, namely, the appointed image data is filled by using the difference part between the image data corresponding to the first system and the appointed image data synchronized to the second system last time, so that the completely filled image data is obtained, the updated image data is displayed, and meanwhile, the updated image data can be stored in a second memory corresponding to the second system.
It should be noted that, in the embodiment of the present application, an electronic device including a dual system is taken as an example for description, and in actual implementation, the electronic device may also be configured with more systems, for example, the electronic device may further include three systems and multiple systems, and the picture display method provided in the embodiment of the present application is applicable to a case where the electronic device includes three systems or multiple systems, and specifically, before and after the systems are switched, the implementation principle and the implementation process of making pictures displayed on the screen of the electronic device 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 pictures displayed on the screen of the electronic equipment can be consistent before and after the system is switched, and convenience is provided for a user to check data.
