[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0031] As users demand higher levels of user experience, the requirements for the performance indicators of the operating systems in smart devices are also increasing, making it possible to set up dual systems on smart devices. However, when switching between systems, the display characteristics of smart devices (such as screen brightness) often switch accordingly, which can affect the user's visual experience to some extent.

[0032] Through long-term research, the inventors discovered that by switching from a first system to a second system while the system is in operation, the brightness parameters corresponding to the first system can be obtained and then sent to the second system. This allows the second system to control the screen of the electronic device to display according to the brightness parameters. Compared to related technologies where the device's display characteristics change after a system switch, affecting the user's visual experience, the above method ensures consistent screen brightness before and after a system switch, thus improving the user's visual experience.

[0033] Therefore, to improve the above-mentioned problems, the inventors have proposed a display method, device, electronic device, and storage medium that enables the screen brightness of the device to remain consistent before and after system switching, thereby improving the user's visual experience. The electronic device in the embodiments of this application can be a mobile phone, smartwatch, tablet computer, laptop computer, PDA, wearable device (e.g., smartwatch), virtual reality (VR) device, augmented reality (AR) device, wireless terminal in industrial control, wireless terminal in autonomous driving, and wireless terminal in smart homes, etc., and the specific device type is not limited.

[0034] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0035] Please see Figure 1 This illustration shows a flowchart of a display method provided in an embodiment of this application. This embodiment provides a display method that can be applied to, for example... Figure 11 The illustrated display device 700 and electronic device configured with the display device 700, the electronic device comprising at least a first system and a second system, wherein the power consumption of the first system is higher than that 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, and the first system and the second system are each configured with applications with different functions. The first system and the second system interact with each other to complete the functions of the electronic device. The first system and the second system share a display device (i.e., they share a single display device). It should be noted that in this embodiment, the first system and the second system can be run by the same processor, the method including:

[0036] Step S110: If the system in operation is switched from the first system to the second system, obtain the brightness parameters corresponding to the first system.

[0037] In this context, a system in operation can be understood as a system responsible for data processing, which may include processing at least one of application data and sensor data.

[0038] As one implementation method, when the screen of an electronic device remains off for a preset duration, a system switch can be triggered. For example, the system in operation can be switched from a first system to a second system. The preset duration is not limited in value; for example, it can be 10 seconds, 15 seconds, 20 seconds, or 30 seconds.

[0039] In some embodiments, the duration for which the screen of an electronic device is in a screen-off state can be detected in real time. When the duration for which the screen of an electronic device is in a screen-off state reaches a preset duration, the system in operation can be triggered to switch from the first system to the second system.

[0040] In other embodiments, when the screen of the electronic device has been in a screen-off state for a preset duration and the screen state of the electronic device has switched from a screen-off state to a screen-on state, the system in operation can be triggered to switch from the first system to the second system.

[0041] For example, in some specific implementations, when the screen of an electronic device has been in a off state for a preset duration, and when the user switches the screen state from off to on by touching a specific function key on the electronic device, the running system is triggered to switch from the first system to the second system. The specific function key may include the power button or the Home button of the electronic device.

[0042] In other specific implementations, if it is pre-set that receiving a message notification from a specific application triggers a switch from a screen-off state to a screen-on state, then the system in operation can be switched from a first system to a second system when the screen of the electronic device has been in a screen-off state for a preset duration and a message notification from the specific application is detected. The specific application may include an instant messaging application, and the message notification from the specific application may be an instant messaging application message notification or an incoming phone call, etc.

[0043] In this embodiment, the brightness parameter represents the current brightness value of the screen of the electronic device. As a method, to prevent abrupt changes in screen brightness before and after system switching, the electronic device can obtain the brightness parameter corresponding to the first system when switching from the first system to the second system, and synchronize this brightness parameter to the second system.

[0044] Step S120: Send the brightness parameters to the second system so that the second system controls the screen of the electronic device to display according to the brightness parameters.

[0045] One approach is to store the acquired brightness parameters of the first system in the memory of the electronic device, send a data acquisition command to the second system, instructing the second system to retrieve the brightness parameters of the first system from the memory, and control the screen of the electronic device to display according to the brightness parameters, thereby ensuring that the display brightness of the screen of the electronic device remains unchanged before and after the system switch.

[0046] For example, in a specific application scenario, such as Figure 2 The diagram shows an example of screen brightness display before and after system switching provided in this embodiment. Figure 2 The image on the left corresponds to the first system, and its brightness value is r. Figure 2 The right side shows the screen corresponding to the second system. When the system is in operation... Figure 2 The first system on the left is switched to Figure 2 When using the second system on the right, the brightness value of the image corresponding to the second system can be the same as the brightness value of the image corresponding to the first system. That is, the brightness value of the image corresponding to the second system is also r. At this time, the content of the image corresponding to the second system can be the same as or different from the content of the image corresponding to the first system.

[0047] Optionally, the acquired brightness parameters of the first system can be stored locally, and a data acquisition command can be sent to the second system to instruct the second system to read the brightness parameters of the first system from the local storage and control the screen of the electronic device to display according to the brightness parameters.

[0048] The display method provided in this embodiment involves switching from a first system to a second system while the system is in operation. The brightness parameters corresponding to the first system are obtained and then sent to the second system, enabling the second system to control the screen of the electronic device to display according to these parameters. Compared to related technologies where system switching also alters the device's display characteristics, affecting the user's visual experience, this solution ensures that the screen brightness of the electronic device when the second system is running is consistent with that when the first system is running. This allows for system switching without the user's visual perception, thus improving the user's visual experience.

[0049] Please see Figure 3 The diagram illustrates a flowchart of a display method according to another embodiment of this application. This embodiment provides a display method applicable to an electronic device, which includes at least a first system and a second system. In this embodiment, the first system and the second system are run by the same processor. The method includes:

[0050] Step S210: If the system in operation is switched from the first system to the second system, obtain the brightness parameters corresponding to the first system.

[0051] Step S220: Send the brightness parameters to the second system so that the second system controls the screen of the electronic device to display according to the brightness parameters.

[0052] Step S230: Obtain the screen data corresponding to the first system.

[0053] In this embodiment of the application, to avoid affecting the user's visual experience by switching the display screen of the electronic device before and after system switching, the electronic device can obtain the screen data corresponding to the first system. Specifically, the standby screen of the electronic device when the system is running as the first system (which can be a fixed standby screen or a periodically switching standby screen) can be determined as the screen data corresponding to the first system, or the last frame displayed before the screen state of the electronic device switches from on state to off state when the system is running as the first system can be determined as the screen data corresponding to the first system. The specific type of screen data corresponding to the first system is not limited.

[0054] In this scenario, when the system in operation is the first system, if no user interaction with the electronic device's screen is detected within a certain timeframe (e.g., 30 seconds, the exact duration is not limited), the screen state can switch from on to off. During this time, the processor can still interact with the first system, while the electronic device's display controller pauses rendering the corresponding screen data. In this case, the screen data corresponding to the first system can be acquired and stored in the electronic device's memory. Therefore, as a method, the screen data corresponding to the first system can be retrieved (read) from this memory.

[0055] As one approach, if the system in operation is detected to switch from the first system to the second system, the screen data corresponding to the first system can be obtained.

[0056] Step S240: Compare the image data with the specified image data that was previously synchronized to the second system to obtain differential image data.

[0057] In this embodiment, the electronic device can 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 a power outage may be different, and the electronic device can store the screen data that was synchronized to the second system in the past.

[0058] Here, differential image data represents the difference between the currently acquired image data corresponding to the first system and the image data previously synchronized to the second system. This difference can specifically include a set of coordinates representing the differences in color values ​​(e.g., RGB values) between the currently acquired image data corresponding to the first system and the image data previously synchronized to the second system. Specified image data represents the image data previously synchronized from the first system to the second system.

[0059] In this system, both the currently acquired image data corresponding to the first system and the image data previously synchronized to the second system consist of several pixels. For the same pixel coordinate, the RGB value of the image data corresponding to the first system and the RGB value of the image data previously synchronized to the second system may be different. Therefore, as a method, the RGB value of the currently acquired image data corresponding to the first system can be compared coordinate by coordinate with the RGB value of the corresponding coordinate position in the specified image data previously synchronized to the second system to obtain the coordinates of the positions where the RGB values ​​differ between the two image data. The number of these coordinates can be one or more. The set of coordinates formed by these coordinates of the positions where the RGB values ​​differ between the two image data is used as the differential image data.

[0060] Step S250: Send the differential image data to the second system so that the second system updates the specified screen data according to the differential image data and displays the updated screen data.

[0061] In one approach, to reduce the amount of data transmitted, differential image data can be sent directly to the second system without sending the overall image data corresponding to the first system to the second system. This allows the second system to update the content of the specified image data based on the differential image data and display the updated image data, while also reducing the amount of data transmitted and saving network bandwidth.

[0062] In a specific application scenario, such as Figure 4 The diagram shows an example of the screen data displayed before and after the system switching provided in this embodiment. Figure 4 The leftmost character represents the standby screen displayed on the electronic device when the system in operation is designated as the first system. When the first system goes into sleep mode or the screen is turned off, the standby screen switches to [other display]. Figure 4 During the black screen transition, when the user clicks the physical button to turn on the screen or taps the screen directly, the running system switches from the first system to the second system. The screen of the electronic device remains the same, ensuring that the screen displays the same image before and after the system switch, thus avoiding a poor visual experience for the user due to frequent screen switching.

[0063] The display method provided in this embodiment ensures consistent screen brightness before and after system switching, improving the user's visual experience. Differential image data, obtained by comparing the screen data corresponding to the first system with the specified screen data previously synchronized to the second system, is sent to the second system. The second system then updates the specified screen data based on the differential image data and displays the updated screen data. This ensures consistent screen display before and after system switching, avoiding poor visual experience caused by frequent screen switching; it also reduces data transmission volume and saves network bandwidth.

[0064] Please see Figure 5 The diagram illustrates a flowchart of a display method according to another embodiment of this application. This embodiment provides a display method applicable to an electronic device, which includes at least a first processor and a second processor. The first processor runs a first system, and the second processor runs a second system; that is, in this embodiment, the first system and the second system are run by different processors. The method includes:

[0065] Step S310: If the system in operation is switched from the first system to the second system, the first processor obtains the brightness parameters corresponding to the first system.

[0066] In this embodiment, if the system in operation switches from the first system to the second system, the first processor can obtain the brightness parameters corresponding to the first system. The principle and specific implementation process of obtaining the brightness parameters corresponding to the first system can be referred to the description in the foregoing embodiments, and will not be repeated here.

[0067] Step S320: The first processor 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.

[0068] In one approach, the first processor can send the brightness parameter to the second processor via a hardware communication link (such as the SPI (Serial Peripheral Interface) bus).

[0069] Optionally, to reduce the performance loss of data acquisition during system switching, a portion of the electronic device's memory can be allocated as sub-memory to store data received by the second processor. This allows the second processor to directly retrieve the required data from the sub-memory without the first processor sending a data retrieval command, and then the second processor retrieving the data from the electronic device's memory. Upon receiving the brightness parameter, the second processor can store it in the sub-memory. When the system switching is complete, the second processor can read the brightness parameter value from the sub-memory and control the electronic device's screen to display according to this value, ensuring consistent screen brightness before and after the system switch.

[0070] In this embodiment, the electronic device may include a display controller. See also... Figure 6 This diagram illustrates a hardware framework schematic of an electronic device provided in an embodiment of this application. Figure 6 As shown, the electronic device in this embodiment may include a first processor, a second processor, a display controller, and a display device. In this manner, while the first processor is sending brightness parameters 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 command to the second processor. This display controller takeover command instructs the second processor to start controlling the display controller, so that the display controller controls the display device (i.e., the screen of the electronic device) of the electronic device to display according to the brightness parameters received by the second processor.

[0071] 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. See also... Figure 7 This illustrates another hardware framework diagram of the electronic device provided in an embodiment of this application. For example... Figure 7 As shown, 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 manner, during the process of sending brightness parameters to the second processor, the first processor may control the first display controller to turn off (i.e., the first processor disconnects from 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 (i.e., the screen of the electronic device) of the electronic device to display according to the brightness parameters received by the second processor.

[0072] The display method provided in this embodiment involves switching from a first system to a second system while the system is in operation. The first processor obtains the brightness parameters corresponding to the first system and then sends these parameters to the second processor, enabling the second processor to control the screen of the electronic device to display according to the brightness parameters. Compared to related technologies where the device's display characteristics change after a system switch, affecting the user's visual experience, this solution ensures consistent screen brightness before and after the system switch, thus improving the user's visual experience.

[0073] Please see Figure 8 The diagram illustrates a flowchart of a display method according to another embodiment of this application. This embodiment provides a display method applicable to an electronic device, which includes at least 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. The method includes:

[0074] Step S410: If the system in operation is switched from the first system to the second system, the first processor obtains the brightness parameters corresponding to the first system.

[0075] Step S420: The first processor 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.

[0076] Step S430: The first processor acquires the screen data corresponding to the first system.

[0077] Optionally, two areas can be allocated from the electronic device's memory to store data received by the first processor and data received by the second processor, respectively. The sub-memory used to store data received by the first processor can be called the first memory, corresponding to the first system. The sub-memory used to store data received by the second processor can be called the second memory, corresponding to the second system. In this approach, after the first processor obtains the screen data corresponding to the first system, it can store this screen data in the first memory corresponding to the first system. This allows it to directly retrieve the historically synchronized screen data from the first memory if the screen data synchronized to the second system differs in the next synchronization.

[0078] Step S440: The first processor compares the image data with the specified image data that was previously synchronized to the second system to obtain differential image data.

[0079] Step S450: The first processor sends the differential image data to the second processor, so that the second processor updates the specified screen data according to the differential image data and displays the updated screen data.

[0080] In one approach, the first processor can send differential image data to the second processor via a hardware communication link. Upon receiving the differential image data, the second processor can directly update the content of the specified screen data previously synchronized from the first system using the differential image data. Specifically, it uses the difference between the currently acquired screen data from the first system and the previously synchronized screen data from the second system to fill in the difference, obtaining complete screen data. The updated screen data is then displayed, and the updated screen data can be stored in the second memory corresponding to the second system.

[0081] It should be noted that the embodiments of this application are illustrated using an electronic device with dual systems as an example. In actual implementation, the electronic device may also be configured with more systems. For example, the electronic device may also include three or more systems. The screen display method provided in the embodiments of this application is applicable to the case where the electronic device includes three or more systems. The specific implementation principle and process of making the screen of the electronic device consistent before and after system switching will not be described here.

[0082] In this embodiment, the electronic device may include at least a first processor and a second processor, or it may include three or more processors. In this way, different processors are used to run different systems, and different processors have different power consumption. When the currently running system switches from a system with relatively high power consumption to a system with relatively low power consumption, the screen of the electronic device can be kept consistent before and after the system switch, thereby providing convenience for users to view data. Examples are not listed here.

[0083] The display method provided in this embodiment ensures consistent screen brightness before and after system switching, improving the user's visual experience. By having the first processor compare the screen data corresponding to the first system with the specified screen data previously synchronized to the second system, differential image data is sent to the second processor. The second processor then updates the specified screen data based on the differential image data and displays the updated screen data. This ensures consistent screen brightness and a consistent display on the electronic device's screen before and after system switching, avoiding poor visual experience caused by frequent screen switching. Simultaneously, it reduces data transmission volume and saves network bandwidth.

[0084] Please see Figure 9The diagram illustrates a flowchart of a display method according to another embodiment of this application. This embodiment provides a display method applicable to an electronic device, which includes at least 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. The method includes:

[0085] Step S510: The second processor receives the brightness parameter corresponding to the first system. The brightness parameter is obtained by the first processor when the system in operation is switched from the first system to the second system.

[0086] Step S520: The second processor controls the screen of the electronic device to display according to the brightness parameter.

[0087] In this embodiment, the electronic device may include a display controller. In this mode, the second processor may respond to the display controller takeover instruction sent by the first processor and start controlling the display controller so that the display controller controls the display device (i.e. the screen of the electronic device) of the electronic device to display according to the brightness parameters.

[0088] In this embodiment, the electronic device may also include at least two display controllers, for example, at least a first display controller and a second display controller. In this manner, the second processor may respond to a display controller takeover command sent by the first processor and activate the second display controller, so that the second display controller controls the display device (i.e., the screen of the electronic device) of the electronic device to display according to the brightness parameters, wherein the display controller takeover command is used to instruct the second processor to activate the second display controller.

[0089] The display method provided in this embodiment ensures that the screen brightness of the device remains consistent before and after system switching, thereby improving the user's visual experience.

[0090] Please see Figure 10 The diagram illustrates a flowchart of a display method according to another embodiment of this application. This embodiment provides a display method applicable to an electronic device, which includes at least 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. The method includes:

[0091] Step S610: The second processor receives the brightness parameter corresponding to the first system. The brightness parameter is obtained by the first processor when the system in operation is switched from the first system to the second system.

[0092] Step S620: The second processor controls the screen of the electronic device to display according to the brightness parameter.

[0093] Step S630: The second processor receives differential image data, which is obtained by the first processor by comparing the screen data corresponding to the first system with the specified screen data previously synchronized to the second system.

[0094] Step S640: The second processor updates the specified screen data according to the differential image data and displays the updated screen data.

[0095] The display method provided in this embodiment ensures that the screen brightness of the device remains consistent before and after system switching, and that the screen display of the electronic device remains consistent before and after system switching. This avoids brightness jumps before and after system switching and prevents users from experiencing poor visual experience due to frequent screen switching. At the same time, it reduces the amount of data transmission and saves network bandwidth.

[0096] Please see Figure 11 This is a structural block diagram of a display device provided in an embodiment of this application. This embodiment provides a display device 700 that can operate in an electronic device, the electronic device including at least a first system and a second system, and the device 700 including: a data acquisition module 710 and a display module 720.

[0097] The data acquisition module 710 is used to acquire the brightness parameters corresponding to the first system if the system in operation is switched from the first system to the second system.

[0098] In one approach, the system in operation can be switched from the first system to the second system when the screen of the electronic device has been in a screen-off state for a preset duration. For example, the system can be switched from the first system to the second system as soon as the screen of the electronic device has been in a screen-off state for the preset duration; alternatively, the system can be switched from the first system to the second system only when the screen of the electronic device has been in a screen-off state for the preset duration and the screen of the electronic device is turned on again.

[0099] In this embodiment, the data acquisition module 710 can also be used to acquire the screen data corresponding to the first system when the system in operation is switched from the first system to the second system.
