The 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 provided by an embodiment of the present application is shown. This embodiment provides a display method, which can be applied to a display device 700 as shown in FIG. 11 and an electronic device equipped with the display device 700. The electronic device includes at least a first system and a second system, wherein the first system The power consumption of one system is higher than the power consumption of the second system. It should be noted that the first system and the second system in this embodiment 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 , complete the function of electronic equipment. The first system and the second system share a display device (ie, share one display device). It should be noted that the first system and the second system in this embodiment may be run by the same processor, and the method includes:

Step S110: If the system in the running state is switched from the first system to the second system, obtain the brightness parameter corresponding to the first system.

The system in the running state may be understood as a system responsible for data processing, wherein the data processing may include processing at least one of application data and sensor data.

As an implementation manner, when the screen of the electronic device is in the off-screen state for a preset period of time, a system switch may be triggered. For example, it may be triggered to switch the system in the running state from the first system to the second system. The value of the preset duration may not be limited, for example, it may be a value such as 10 seconds, 15 seconds, 20 seconds, or 30 seconds.

In some embodiments, the duration that the screen of the electronic device is in the off-screen state can be detected in real time, and when it is detected that the screen of the electronic device is in the off-screen state for a preset duration, the system in the running state can be triggered from the first The system is switched to the second system.

In other embodiments, when it is detected that the screen of the electronic device is in the off-screen state for a preset time period, and the screen state of the electronic device is switched from the off-screen state to the bright-screen state, the running state can be triggered. The system is switched from the first system to the second system.

For example, in some specific implementations, when it is detected that the screen of the electronic device is in the off-screen state for a preset duration, and it is detected that the user touches a specific function key of the electronic device to change the screen state of the electronic device from off-screen When the state is switched to the bright screen state, the system in the running state is triggered to switch from the first system to the second system. Wherein, the specific function key may include an on/off key or a Home key of the electronic device.

In other specific implementations, if it is pre-set that when a message notification of a specific application is received, the screen is triggered to switch from the off-screen state to the bright-screen state, then when it is detected that the screen of the electronic device is in the off-screen state When the duration reaches the preset duration, and when it is detected that a message notification of a specific application is received, the system in the running state is triggered to switch from the first system to the second system. 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 phone call.

In this embodiment of the present application, the brightness parameter represents the current brightness value of the screen of the electronic device. As a method, in order to prevent the brightness of the screen of the electronic device from jumping before and after the system switching, the electronic device can obtain the brightness parameter corresponding to the first system when the system in the running state is switched from the first system to the second system to obtain the brightness parameter corresponding to the first system. Synchronize the brightness parameter to the second system.

Step S120: Send the brightness parameter to the second system, so that the second system controls the screen of the electronic device to display according to the brightness parameter.

As a way, the acquired brightness parameters of the first system can be stored in the 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 parameters 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 does not change before and after the system switching.

For example, in a specific application scenario, as shown in FIG. 2 , an example diagram of brightness display of the screen before and after system switching provided by this embodiment is shown. The left side of FIG. 2 is a picture corresponding to the first system, and its brightness value is r, and the right side of FIG. 2 is a picture corresponding to the second system. When the system in the running state is switched from the first system on the left of FIG. 2 to the second system on the right of FIG. 2 , the brightness value of the picture corresponding to the second system can be the same as the brightness value of the picture corresponding to the first system, that is, at this time The brightness value of the picture corresponding to the second system is also r, and at this time, the content of the picture corresponding to the second system and the content of the picture corresponding to the first system may be the same or different.

Optionally, the acquired brightness parameters of the first system can also be stored locally, and a data acquisition instruction can be sent to the second system to instruct the second system to read the brightness parameters of the first system locally, and control the brightness parameters of the electronic device. The screen displays according to the brightness parameter.

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 brightness parameters corresponding to the first system are obtained, and then the brightness parameters are sent to the second system, so that the second system controls The screen of the electronic device is displayed according to the brightness parameter. Compared with the problem in the related art that the display characteristics of the device will also be switched after the system is switched, which will affect the user's visual experience, this solution makes the screen brightness of the electronic device when the second system is in the running state, and the electronic device when the first system is in the running state. The brightness of the device screen is consistent, so that the system switching can be completed without the user's sight perception, which improves the user's visual experience.

Please refer to FIG. 3 , which shows a flowchart of a display method provided by another embodiment of the present application. This embodiment provides a display method, which can be applied to an electronic device, where the electronic device at least includes a first system and a second system. Two systems, the first system and the second system in this embodiment are run by the same processor. The method includes:

Step S210: If the system in the running state is switched from the first system to the second system, obtain the brightness parameter corresponding to the first system.

Step S220: Send the brightness parameter to the second system, so that the second system controls the screen of the electronic device to display according to the brightness parameter.

Step S230: Acquire picture data corresponding to the first system.

In the embodiments of the present application, in order to prevent the display screen of the electronic device from being switched before and after the system switching and affecting the user's visual experience, the electronic device may acquire screen data corresponding to the first system. Wherein, the standby screen of the electronic device when the system in the running state is the first system (it can be a fixed standby screen or a periodically switched standby screen) can be determined as the screen data corresponding to the first system, or the screen data corresponding to the first system can be determined. When the system in the running state is the first system, and the screen state of the electronic device is switched from the screen-on state to the screen-off state, the last frame displayed is determined as the screen data corresponding to the first system, and the screen data corresponding to the first system is determined. The specific type may not be limited.

Wherein, when the system in the running state is the first system, if the user's operation on the screen of the electronic device is not detected within a certain period of time (for example, within 30 seconds, the value of the specific time period may not be limited), the screen status of the electronic device is not detected. You can switch from the on-screen state to the off-screen state. At this time, the processor can still perform data interaction with the first system, and the display controller of the electronic device suspends rendering the picture data corresponding to the first system. In this case, the picture data corresponding to the first system can be obtained, and store the picture data corresponding to the first system in the memory of the electronic device. Therefore, as a way, the picture data corresponding to the first system can be acquired (read) from the memory.

As a method, if it is detected that the system in the running state is switched from the first system to the second system, the screen data corresponding to the first system can be acquired.

Step S240: Compare the picture data with the designated picture data that was synchronized to the second system last time to obtain differential image data.

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 the power failure can be different, and the electronic device can synchronize the historical screen data. The screen data of the second system is synchronized for storage.

The differential image data represents the difference between the currently acquired image data corresponding to the first system and the image data synchronized to the second system last time, and the difference may specifically include the currently acquired image corresponding to the first system A set consisting of coordinates with different color values (eg, RGB values) between the data and the picture data last synchronized to the second system. The specified picture data represents the picture data that the first system synchronized to the second system last time.

Among them, the currently obtained picture data corresponding to the first system and the picture data synchronized to the second system last time are composed of several pixels. For the position where the coordinates of the same pixel point are located, the first system corresponds to The RGB value of the picture data may be different from the RGB value of the picture data synchronized to the second system last time. Therefore, as a method, the RGB value of the currently obtained picture data corresponding to the first system can be compared with the RGB value of the corresponding coordinate position in the specified picture data synchronized to the second system on a coordinate-by-coordinate basis, and two For the position coordinates of different RGB values in the picture data, the number of the position coordinates may be one or more, and the coordinate set composed of the position coordinates with different RGB values in the two picture data is used as the differential image data.

Step S250: Send the difference image data to the second system, so that the second system updates the specified screen data according to the difference image data, and displays the updated screen data.

As a way, in order to reduce the amount of data transmission, the differential image data can be directly sent to the second system without sending the overall picture data corresponding to the first system to the second system, so that the second system can The content of the specified screen data is updated, and the updated screen data is displayed. At the same time, the data transmission quantity can be reduced and the network transmission bandwidth can be saved.

In a specific application scenario, as shown in FIG. 4 , an example diagram of picture data displayed on the screen before and after system switching provided by this embodiment is shown. The leftmost part of FIG. 4 represents the standby screen displayed on the screen of the electronic device when the system in the running state is the first system, and when the first system sleeps or turns off the screen, the standby screen displayed on the screen switches to the one in the middle of FIG. 4 . When the user clicks the physical button used to turn on 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 on the screen of the electronic device is still the standby screen, The images displayed on the screen of the electronic device before and after the system switching are made consistent, which avoids the user from producing bad visual experience due to frequent switching of images.

The display method provided in this embodiment realizes that the screen brightness of the device is displayed in a consistent manner before and after system switching, thereby improving the user's visual experience. The difference 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 is sent to the second system, and the second system updates the specified picture data according to the difference image data , and display the updated screen data. The images displayed on the screen of the electronic device before and after the system switching are consistent, which avoids the user from producing bad visual experience due to frequent switching of images; meanwhile, the quantity of data transmission is reduced, and the network transmission bandwidth is saved.

Please refer to FIG. 5 , which shows a flowchart of a display method provided by another embodiment of the present application. This embodiment provides a display method, which can be applied to an electronic device, where the electronic device at least includes a first processor and A second processor, where the first processor is used to run the first system, and the second processor is used to run the second system, that is, the first system and the second system in this embodiment are run by different processors. The method includes:

Step S310: 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 can obtain the brightness parameter corresponding to the first system, wherein the principle and specific details of obtaining the brightness parameter corresponding to the first system For the implementation process, reference may be made to the descriptions in the foregoing embodiments, which are not repeated here.

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.

As a way, the first processor may send the brightness parameter to the second processor through a hardware communication link (such as an SPI (Serial Peripheral Interface, serial peripheral interface) bus).

Optionally, in order to reduce the performance loss of acquiring data during system switching, a part of the memory of the electronic device can be opened up as a sub-memory for storing data received by the second processor, so that the second processor can directly The required data is retrieved from the sub-memory without the need for the second processor to acquire data from the memory of the electronic device after the first processor sends a data acquisition instruction to the second processor. After receiving the brightness parameter, the second processor can store the brightness parameter in the sub-memory, so that when the system switching is completed, the second processor can read the brightness parameter value from the sub-memory, and control the electronic The screen of the device is displayed according to the brightness parameter value, so that the brightness of the screen of the electronic device is displayed the same before and after the system switching.

In this embodiment, the electronic device may include a display controller. Referring to FIG. 6 , a schematic diagram of a hardware framework of an electronic device provided by 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 display controller, and a display device. In this way, when the first processor sends the brightness parameter to the second processor, the first processor can stop controlling the display controller (that is, the first processor is still connected to the display controller, but The first processor no longer controls the display controller), and sends a display controller takeover instruction to the second processor, 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 (ie, the screen of the electronic device) displays 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, another schematic diagram of a hardware framework of the electronic device provided by the 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, when the first processor sends the brightness parameter to the second processor, the first processor can 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 (ie 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 acquires 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 in the related art that the display characteristics of the device will also be switched after the system is switched, which will affect the user's visual experience, this solution realizes the consistent display of the screen brightness of the device before and after the system is switched, which improves the user's visual experience.

Please refer to FIG. 8 , which shows a flowchart of a display method provided by another embodiment of the present application. This embodiment provides a display method, which can be applied to an electronic device, where the electronic device at least includes a first processor and a second processor, where the first processor is used to run the first system, the second processor is used to run the second system, and the method includes:

Step S410: 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: 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.

Step S430: the first processor acquires the picture data corresponding to the first system.

Optionally, two areas may be opened up from the memory of the electronic device, which are respectively used to store the data received by the first processor and the data received by the second processor. The sub-memory for storing data received by the first processor may be referred to as the first memory, the first memory corresponds to the first system, and the sub-memory for storing data received by the second processor may be referred to as the first memory is the second memory, and the second memory corresponds to the second system. In this way, after acquiring the picture data corresponding to the first system, the first processor can store the picture data in the first memory corresponding to the first system, so as to facilitate the next synchronization to the picture data of the second system At the same time, the picture data that is historically synchronized to the second system can be directly obtained from the first memory.

Step S440: The first processor compares the picture data with the specified picture data that was synchronized to the second system last time, to obtain differential image data.

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 updates the The following screen data is displayed.

As one approach, the first processor may send the differential image data to the second processor via a hardware communication link. After the second processor receives the differential image data, it can directly use the differential image data to update the content of the specified screen data synchronized by the first system last time, that is, use the currently acquired screen data corresponding to the first system and the last time Synchronize the difference between the designated screen data to the second system, fill in the designated screen data, obtain the complete screen data, and display the updated screen data. At the same time, the updated screen data can be stored in the in the second memory corresponding to the second system.

It should be noted that the embodiments of the present application are described by taking the electronic device including 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 systems and multiple systems. The image display method provided by the embodiment is suitable for the situation that the electronic device includes three systems or multiple systems. Specifically, before and after system switching, the implementation principle and implementation process of making the images displayed on the screen of the electronic device consistent will not be repeated here.

In this embodiment of the present application, in addition to at least the first processor and the second processor, the electronic device may also include three or more processors. In this way, different processors are used to run different systems. And the power consumption corresponding to different processors is different. When the currently running system is switched from a system with relatively high power consumption to a system with relatively low power consumption, it can be realized that the screen displayed on the screen of the electronic device is consistent before and after the system switching, thereby providing convenience for users to view data. There are no examples here.

The display method provided in this embodiment realizes that the screen brightness of the device is displayed in a consistent manner before and after system switching, thereby improving the user's visual experience.
