[0029] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0030] It is understood that the terms "first", "second", etc. used in this application may be used herein to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish a first element from another element. For example, without departing from the scope of this application, a first client may be referred to as a second client, and similarly, a second client may be referred to as a first client. Both the first client and the second client are clients, but they are not the same client.

[0031] FIG1 is a schematic diagram of an application environment of a screen-off display control method in an embodiment. As shown in FIG1 , the application environment includes a mobile device 100. The mobile device 100 can run at least two operating systems, and at least two operating systems share the same screen. The mobile device 100 includes at least two processors, one processor running one operating system. Taking the mobile device 100 running the first operating system and the second operating system as an example, the power consumption of the mobile device 100 running the first operating system is greater than the power consumption of running the second operating system. After receiving the screen-off instruction or the automatic screen-off instruction triggered by the user's key, the mobile device 100 enters the screen-off state, detects whether the screen-off display condition is met, and switches the screen control right of the mobile device 100 from the first operating system to the second operating system when the mobile device 100 meets the screen-off display condition, and then performs screen-off display when the second operating system controls the screen of the mobile device. In this way, the screen is off-screen displayed under the control of the low-power operating system, avoiding the problem of high power consumption caused by refreshing the screen when the screen is off-screen displayed under the high-power operating system, reducing power consumption, and extending the battery life of the mobile device. The mobile device 100 can be a smart phone, a tablet computer, or a wearable device. The wearable device may be a wearable device such as a smart watch, a smart bracelet, or a smart glasses that includes at least two operating systems.

[0032] Figure 2 FIG. 1 is a flow chart of a method for controlling screen-off display in an embodiment. The method for controlling screen-off display in this embodiment is described by taking the mobile device in FIG. 1 as an example. Figure 2 As shown, a screen-off display control method includes steps 202 to 204.

[0033] Step 202: when the mobile device is in a screen-off state, if the mobile device meets a screen-off display condition, the screen control right of the mobile device is switched to the second operating system.

[0034] The screen-off state means that the screen of the mobile device is off. The mobile device receives a screen-off instruction, controls the screen to be off according to the screen-off instruction, and enters the screen-off state. The screen-off instruction may be a screen-off instruction automatically generated by the mobile device when it times out, or a screen-off instruction generated by the mobile device receiving an active operation of the user. The screen-off instruction automatically generated by the mobile device when it times out includes: presetting a screen-off duration threshold, and when the mobile device detects that the screen-off duration threshold is reached without receiving a trigger signal, the screen-off instruction is generated. The screen-off instruction generated by the mobile device receiving an active operation of the user includes: the mobile device receives a screen-off instruction generated by a user trigger operation or a voice operation. The trigger operation may include an operation on the power button, or a trigger operation on the screen-off control on the screen, or an operation on the volume button, etc. The screen-off instruction generated by the voice operation may include the mobile device receiving a voice message sent by the user, recognizing the voice message to obtain a corresponding voice screen-off instruction, for example, the user speaks "Xiaoy, please turn off the screen", and the voice assistant of the mobile device recognizes the sentence and generates a screen-off instruction.

[0035] The mobile device controls the screen to turn off according to the screen-off instruction, and can monitor the screen-off broadcast message notification through a monitoring application. When the screen-off broadcast message notification is received, it is determined that the screen enters the screen-off state.

[0036] The screen-off display conditions can be set in advance as needed. Usually, it can be set whether the screen-off display is allowed, the time range for allowing the screen-off display, etc., but it is not limited to this.

[0037] Specifically, when the mobile device detects the screen-off instruction, it controls the screen to be turned off and enter the screen-off state, and then detects whether it meets the screen-off display conditions.

[0038] At least two operating systems can be run on a mobile device at the same time. Usually, operating systems with multiple functions and strong performance consume more power when running. The at least two operating systems include a first operating system and a second operating system. The power consumption of the mobile device running the first operating system is greater than the power consumption of the second operating system.

[0039] At least two operating systems may include an Android operating system, a Linux operating system, an RTOS (Real Time Operating System) operating system, etc. Among them, the Android operating system and the Linux operating system can provide rich functions, strong performance, and high power consumption. The RTOS operating system can provide simple functions and low power consumption. For example, the first operating system is an Android operating system, and the second operating system is an RTOS operating system.

[0040] Multiple operating systems on a mobile device share the same screen. One processor runs one operating system. Only one processor can have control of the screen at the same time. Only the operating system that obtains control of the screen can display content on the screen. In order to save power by turning off the screen, when the conditions for turning off the screen are met, the screen control is switched to the target operating system with lower power consumption.

[0041] When three or more operating systems are running on a mobile device, the power consumption of each operating system can be compared, and then the operating systems can be sorted from large to small or from small to large according to the power consumption, and then a target operating system is selected according to the power consumption, and the power consumption of the target operating system is not the highest power consumption operating system.

[0042] When the first operating system and the second operating system are running on the mobile device, the second operating system with low power consumption is used as the target operating system.

[0043] The screen control right can be switched through the screen driver, and the screen control right can be transferred to the target operating system through the screen driver.

[0044] Step 204, when the second operating system controls the screen of the mobile device, the screen is turned off.

[0045] Off-screen display refers to displaying the off-screen content in the off-screen state. The off-screen content can be preset content or system default content. The preset content can be the content that the user pre-sets to be displayed when the screen is off, such as time, weather, etc. The system default content can be the content configured by the system, such as time, etc. When the target operating system controls the screen, the AOD interface is drawn to realize the off-screen display, and the screen display content is refreshed. The refresh operation can be completed through the LVGL library control. In addition, the first operating system can be shut down or hibernated.

[0046] In one embodiment, the changed area in the screen may be detected, and the changed area may be refreshed, while the unchanged area may not be refreshed.

[0047] In this embodiment, the screen-off display control is applied to a mobile device that can run at least two operating systems. When the mobile device is in the screen-off state, it is detected that the mobile device meets the screen-off display condition, and the screen control of the mobile device is switched to the second operating system. The screen is displayed off in the second operating system, avoiding high power consumption caused by refreshing the screen in the high-power first operating system, reducing power consumption, and extending the battery life of the mobile device.

[0048] In an optional embodiment of the present application, the screen-off display condition may include a screen-off display time range. If the mobile device satisfies the screen-off display condition in step 202, the screen control right of the mobile device is switched to the second operating system, including: if it is detected that the current moment is within the screen-off display time range, the screen control right of the mobile device is switched to the second operating system.

[0049] The screen off display time range refers to the pre-set screen off display time interval, including the screen off display start time and the screen off display end time. Usually the screen off display time range can be customized by the user, for example, the screen off display time range in a day is 7:00 to 21:30, 8:10 to 21:30, etc., but not limited to this. If the screen off display time range is not set for a specific period, it can be defaulted to any time.

[0050] The current time may be the time when the mobile device enters the screen-off state, or the time after a preset time has passed after entering the screen-off state, etc. After the mobile device enters the screen-off state, it detects whether the current time is within the screen-off display time range, that is, the current time is compared with the start time and the end time of the screen-off display time range, respectively, to determine whether the current time is greater than the start time and less than the end time. When the current time is greater than or equal to the start time and less than or equal to the end time, the current time is within the screen-off display time range, indicating that the mobile device meets the screen-off display condition; when the current time is less than the start time or greater than the end time, the current time is not within the screen-off display time range, indicating that the mobile device does not meet the screen-off display condition.

[0051] In this embodiment, the current time is obtained after the mobile device enters the screen-off state, and the current time is compared with the screen-off display time range, so as to quickly determine whether the mobile device meets the screen-off display condition.

[0052] In an optional embodiment of the present application, the above-mentioned screen-off display condition may include not only the screen-off display time range, but also the state of the screen-off display function switch. Step 202, if the mobile device meets the screen-off display condition, switching the screen control right of the mobile device to the second operating system includes: if the screen-off display function switch is in the on state and the current moment is within the screen-off display time range, switching the screen control right of the mobile device to the second operating system.

[0053] Before detecting whether the current moment is within the screen-off display time range, the screen-off display control method also includes: detecting the state of the screen-off display function switch; when the screen-off display function switch is in the off state, it indicates that the mobile device does not meet the screen-off display conditions; when the screen-off display function switch is in the on state, continuing to execute the step of detecting whether the current moment is within the screen-off display time range.

[0054] Specifically, a screen-off display function switch is pre-set. When the screen-off display function switch is turned on, it means that the screen-off display is allowed. When the screen-off display function switch is turned off, it means that the screen-off display is not allowed.

[0055] After receiving the screen-off instruction to control the screen to turn off, the mobile device enters the screen-off state and first detects the state of the screen-off display function switch. When the screen-off display function switch is in the on state, it indicates that the screen-off display is allowed, and then continues to detect whether the current time is within the screen-off display time range. When the current time is within the screen-off display time range, it indicates that the mobile device meets the screen-off display condition; when the current time is not within the screen-off display time range, it indicates that the mobile device does not meet the screen-off display condition. When the screen-off display function switch is in the off state, it indicates that the screen-off display is not allowed, and the screen is directly turned off normally.

[0056] By setting the off-screen display function switch, users can flexibly control the off-screen display function and turn it on or off according to personal needs, making the off-screen display function more flexible to control.

[0057] In an optional embodiment of the present application, the screen off display control method also includes: when the screen control of the mobile device belongs to the first operating system, obtaining input screen off display configuration information, the screen off display configuration information including the status of the screen off display function switch and the screen off display time range; the first operating system transmits the screen off display configuration information to the second operating system.

[0058] The dual system of a mobile device is a hardware architecture based on two processor chips. Each processor runs an independent operating system, and the two operating systems interact with each other to complete the functions of the hardware device. In the dual system architecture of a mobile device, the first operating system is a large core system, and the second operating system is a small core system. The large core system belongs to the main processor system in the dual system architecture, and generally may include operating systems such as Android operating system and Linux operating system. The small core system belongs to the slave processor system in the dual system architecture, and generally may include an RTOS operating system. The first operating system and the second operating system can communicate through a dual-core communication method. The dual-core communication method is a communication method for realizing data interaction between two operating systems. In one embodiment, there are sleep and wake-up status bars for the large core system, and the small core system is always in the wake-up state.

[0059] When the first operating system controls the screen of the mobile device, the off-screen display configuration information input in the off-screen display configuration interface of the first operating system is obtained, and the off-screen display configuration information includes the state of the off-screen display function switch and the off-screen display time range. Figure 3As shown, when the first operating system controls the screen of the mobile device, set it in the setting control-display and brightness-off screen clock. The off screen display function switch is displayed at the off screen clock. When the switch is turned on, the AOD time setting item will be displayed. The user enters the AOD time period through the keyboard, such as 9:00 to 21:00. If the time is not set, any time is allowed by default.

[0060] When the first operating system controls the screen, it has the authority to configure the configuration information displayed when the screen is off, which is convenient for user configuration, meets personalized needs, ensures the stability of configuration permissions, improves security, and avoids confusion in configuration permissions.

[0061] In an optional embodiment of the present application, the screen-off configuration information also includes screen-off display content;

[0062] The performing screen-off display includes: displaying the screen-off display content on the screen of the mobile device.

[0063] Among them, the off-screen display content, i.e., the AOD interface display content, can be configured according to user needs, such as time, weather, PM value, etc. The weather may include at least one of type, temperature, humidity, etc. The type may be sunny, cloudy, rainy, snowy, etc., and may be displayed using corresponding icons. The temperature may be the local temperature, such as 20 degrees Celsius, etc.

[0064] In an optional embodiment of the present application, the system may provide multiple off-screen display contents for the user to select, the first operating system obtains the off-screen display content selected by the user, and sends the off-screen display content to the second operating system.

[0065] In an optional embodiment of the present application, each off-screen display content may correspond to a unique content label, the first operating system obtains the target content label selected by the user, and sends the target content label to the second operating system, when the screen is off, the second operating system obtains the corresponding off-screen display content according to the target content identifier and displays it off. By sending the content label to the second operating system, the amount of data transmission between the first operating system and the second operating system can be reduced, saving system resources.

[0066] In an optional embodiment of the present application, the at least two operating systems include a first operating system and a second operating system, and the power consumption of the mobile device running the first operating system is greater than the power consumption of the mobile device running the second operating system; the target operating system is the second operating system;

[0067] Switching the screen control of the mobile device to the second operating system in step 204 includes: the first operating system sends a switching instruction for screen control, and receives a switching result corresponding to the switching instruction, the switching result being a switching result of switching the screen control of the mobile device from the first operating system to the second operating system according to the switching instruction; after the first operating system determines that the switching result is a successful screen control switch, the first operating system sends a screen switching success message to the second operating system, and the second operating system controls the screen of the mobile device.

[0068] When the mobile device meets the conditions for turning off the screen, the first operating system sends a switching instruction for screen control to the screen driver; the screen driver transfers the screen control of the first operating system to the second operating system according to the switching instruction, obtains the switching result, and returns the switching result to the first operating system; after determining that the switching result is that the screen control is successfully switched, the first operating system sends a screen switching success message to the second operating system, and the second operating system controls the screen of the mobile device.

[0069] In an optional embodiment, the screen driver returns a screen switching parameter to the first operating system, and the screen switching parameter is used to characterize the ownership of the screen control right. The first operating system determines that the screen switching is successful according to the screen switching parameter, and then sends a screen switching success message to the second operating system, and the second operating system controls the screen of the mobile device.

[0070] In an optional embodiment, the first processor corresponding to the first operating system and the second processor corresponding to the second operating system can be connected to the screen through a screen control switch. At the same time, only one processor is connected to the screen through the screen control switch. At this time, the operating system run by the processor connected to the screen through the screen control switch obtains the screen control right. When the mobile device meets the screen off display condition, the first operating system sends a switching instruction for the screen control right to the screen control switch; the screen control switch transfers the screen control right of the first operating system to the second operating system according to the switching instruction, that is, the screen control switch controls the second processor to connect to the screen, obtains the switching result, and returns the switching result to the first operating system; after determining that the switching result is that the screen control right is successfully switched, the first operating system sends a screen switching success message to the second operating system, and the second operating system controls the screen of the mobile device.

[0071] In an optional embodiment, the screen control switch returns a screen switching parameter to the first operating system, where the screen switching parameter is used to indicate ownership of the screen control right.

[0072] In an optional embodiment of the present application, after the screen-off display is performed, the method further includes: exiting the screen-off display when it is detected that the mobile device meets the screen-off display exit condition.

[0073] Among them, the screen-off display exit conditions can be set as needed, and usually the screen-off display exit conditions may include active exit conditions and passive exit conditions. Active exit conditions refer to conditions related to screen-off display control. Active exit conditions may include the current time exceeding the screen-off display time range. Passive exit conditions refer to conditions where the screen-off display is interrupted by other applications. Passive exit conditions may include being triggered by a preset event and needing to wake up an operating system with multiple functions and high performance to handle it. By setting the screen-off display exit conditions, you can automatically exit the screen-off display.

[0074] In an optional embodiment of the present application, when it is detected that the mobile device meets the screen-off display exit condition, the screen-off display is exited, including: when it is detected that the current time exceeds the screen-off display time range, the screen-off display is exited.

[0075] The screen off display time range refers to the pre-set screen off display time interval, including the screen off display start time and the screen off display end time. After entering the screen off display, it is detected whether the current time is within the screen off display time range. If it is not within the screen off display time range, it means that the mobile device meets the screen off display exit condition and exits the screen off display.

[0076] In an optional embodiment of the present application, when it is detected that the mobile device meets the screen-off display exit condition, the screen-off display is exited, including: when a preset event is detected, the screen-off display is exited. The preset event is a pre-set event for exiting the screen-off display, such as an alarm event, an incoming call event, a charging event, etc. By configuring the preset event to trigger the exit of the screen-off display, some basic functions of the mobile device can be guaranteed, such as the alarm function, the incoming call answering function, the charging detection function, etc.

[0077] In an optional embodiment of the present application, the at least two operating systems include a first operating system and a second operating system, and the power consumption of the mobile device running the first operating system is greater than the power consumption of the mobile device running the second operating system.

[0078] The exiting the screen-off display includes: waking up the first operating system, switching the screen control of the mobile device from the second operating system to the first operating system; and the first operating system notifying the second operating system to exit the screen-off display.

[0079] Specifically, after waking up the first operating system, the first operating system sends a screen switching instruction to the screen driver or screen control switch, and the screen driver or screen control switch switches the screen control of the mobile device from the second operating system to the first operating system according to the screen switching instruction. The first operating system notifies the second operating system to exit the off-screen display, i.e., the AOD interface display, and the first operating system takes over the screen.

[0080] By waking up the first operating system and implementing the screen switching operation, it is possible to prevent the situation where any system or application can switch screens and prevent confusion in screen state control.

[0081] In an optional embodiment of the present application, when it is detected that the mobile device meets the screen-off display exit condition, after exiting the screen-off display, the method further includes: displaying the interface content of the second operating system on the screen.

[0082] Specifically, when the second operating system controls the screen of the mobile device, it is detected that the screen-off display exit condition is met, and after exiting the screen-off display, normal display is performed directly when the second operating system controls the screen, that is, the interface content of the second operating system is displayed on the screen.

[0083] In an optional embodiment of the present application, before the mobile device is in the screen-off state, the screen-off display control method further includes: obtaining the current usage status of the mobile device and saving the usage status.

[0084] After exiting the screen-off display, the method further includes: reading the usage status and restoring to the usage status.

[0085] By saving the usage status of the mobile device before the screen is turned off, the usage status can be read when the screen is turned off, and then the mobile device is restored to the usage status, which saves user operation time and improves human-computer interaction efficiency.

[0086] In an optional embodiment of the present application, reading the usage status and restoring to the usage status includes: reading the usage status, and restoring to the usage status when detecting that the usage status is a preset usage status.

[0087] The preset usage state may be a pre-set usage state, such as an audio playback state, a motion detection state, etc. The preset usage state is generally a state that the user needs to use. After exiting the off-screen display, it automatically returns to the usage state without the user having to operate again, thereby reducing user operations and improving human-computer interaction efficiency.

[0088] In order to make the scheme of the off-screen display control method provided in the present application clearer, the specific process of the off-screen display control method is described below by taking running dual systems on a mobile device as an example. Figure 4 FIG. 1 is a block diagram of an AOD power saving display control structure of a mobile device based on a dual system in one embodiment. Figure 4As shown, the mobile device 400 includes a display screen 410, a first operating system 420 and a second operating system 430. The display screen 410 is shared by the first operating system 420 and the second operating system 430. Only one operating system can use the display screen 410 at a certain moment, and the screen control right can be switched between the first operating system 420 and the second operating system 430 according to the current state of the mobile device. When the mobile device meets the AOD display conditions, the first operating system 420 actively gives up the screen control right and switches the screen control right to the second operating system 430. The first operating system 420 notifies the second operating system 420 to enter the AOD display state through dual-core communication, and synchronizes the AOD configuration information to the second operating system 430. The second operating system 430 begins to take over the display screen 410, draws the corresponding AOD interface according to the off-screen display content in the AOD configuration information synchronized by the first operating system 420, and is responsible for the display and refresh operations of the AOD interface.

[0089] Figure 5 For application Figure 4 Flow chart of a method for controlling screen-off display of a mobile device. Figure 5 As shown, the screen-off display control method includes:

[0090] Step 502: After the dual-system mobile device is normally started, the first operating system first takes over the screen control right and displays the first operating system interface on the mobile device screen.

[0091] Step 504: Acquire AOD configuration information on the first operating system interface. The AOD configuration information includes AOD function switches, AOD time range, AOD interface display content, and the like.

[0092] AOD configuration information refers to the off-screen display configuration information. AOD function switch refers to the off-screen display function switch. AOD time range refers to the off-screen display time range, including the off-screen display start time and end time, which is used to determine the AOD entry or exit time. AOD interface display content refers to the off-screen display content, which is used to determine what kind of AOD interface is displayed.

[0093] Step 506: The mobile device receives the screen-off instruction and controls the screen to turn off.

[0094] The mobile device detects that the screen-off time threshold is reached without receiving a trigger signal, generates a screen-off instruction, or receives a screen-off instruction generated by a user trigger operation or voice operation, and controls the screen to turn off.

[0095] Step 508, the mobile device determines whether the mobile device meets the AOD display condition according to the AOD configuration information, first obtains the AOD function switch state in the AOD configuration information, if the AOD function switch state is on, it means that the AOD function is turned on, further obtains the current time of the mobile device, matches the current time with the AOD time range, if the current time is within the AOD time range, the AOD display condition is met. If the AOD function switch state is off, or the current time is not within the AOD time range, the AOD display condition is not met.

[0096] Step 510: If the AOD display condition determination fails, the mobile device does not meet the AOD display condition, and the screen is controlled to turn off and sleep.

[0097] Step 512, if the mobile device meets the AOD display conditions, the first operating system initiates a screen switching operation to the screen driver, and the screen driver switches the screen control from the first operating system to the second operating system. After the screen switching is successful, the first operating system notifies the second operating system of the screen switching success through a dual-core communication message, and the second operating system takes over the screen at this time.

[0098] Step 514, the first operating system enters a sleep state after switching the screen. Except for being awakened by preset events such as alarm events, incoming call events or charging events, the first operating system is in a sleep state for the rest of the time. Because in the off-screen display state, the first operating system no longer needs to refresh the AOD interface display content, thereby saving CPU usage and saving power consumption of the mobile device.

[0099] Step 516, after the second operating system takes over the screen display, it starts drawing and displaying the AOD interface according to the AOD configuration information transmitted by the first operating system through dual-core communication, and is responsible for the periodic refresh operation of the AOD interface. The second operating system can refresh the screen at a fixed refresh frequency. During the screen refresh process, the screen can be refreshed in different areas. The areas where the screen content has not changed are not refreshed, and the areas where the screen content has changed are refreshed, thereby reducing the refresh time and power consumption.

[0100] Step 518, while displaying the AOD interface, the second operating system monitors in real time whether the mobile device meets the AOD exit condition. AOD exit conditions are divided into active exit conditions and passive exit conditions. When the second operating system detects that the current time exceeds the AOD display time period (i.e., the AOD time range) based on the AOD time range in the AOD configuration information, it actively wakes up the first operating system to initiate an exit from the off-screen display; when the second operating system detects a preset event such as an incoming call event, an alarm event, or a charging event, the first operating system in a dormant state is awakened, and after the first operating system is awakened, it initiates an exit from the off-screen display.

[0101] Step 520: wake up the first operating system.

[0102] Step 522, after waking up, the first operating system initiates a screen switching instruction to the screen driver, and the screen driver switches the screen control from the second operating system to the first operating system. The first operating system notifies the second operating system to exit the AOD interface display, and the first operating system takes over the screen again.

[0103] In this embodiment, the AOD interface display and refresh are completed by the second operating system by utilizing the low power consumption characteristics of the second operating system, and the first operating system enters a dormant state. Compared with the traditional AOD display process, the first operating system must be in an awake state, which saves the standby power consumption of the mobile device and extends the battery life of the mobile device. The screen switching between the first operating system and the second operating system, the interface display and refresh, and the entry and exit process of the AOD display are completely completed automatically by the mobile device, which improves the interaction efficiency.

[0104] In an optional embodiment of the present application, a screen-off display control method is applied to a mobile device, wherein the mobile device is capable of running at least two operating systems, and the method comprises: when the mobile device is in a screen-off state, if the mobile device meets a screen-off display condition, switching the screen control right of the mobile device to a target operating system, wherein the target operating system is any other operating system among the at least two operating systems except the operating system with the highest power consumption; and when the target operating system controls the screen of the mobile device, performing screen-off display.

[0105] Multiple operating systems on a mobile device share the same screen. One processor runs one operating system. Only one processor can have control of the screen at the same time. Only the operating system that obtains control of the screen can display content on the screen. In order to save power by turning off the screen, when the conditions for turning off the screen are met, the screen control is switched to the target operating system with lower power consumption.

[0106] When three or more operating systems are running on a mobile device, the power consumption of each operating system can be compared, and then the operating systems can be sorted from large to small or from small to large according to the power consumption, and then a target operating system is selected according to the power consumption, and the power consumption of the target operating system is not the highest power consumption operating system.

[0107] When the first operating system and the second operating system are running on the mobile device, the second operating system with low power consumption is used as the target operating system.

[0108] The switching of screen control rights can be achieved through the screen driver, and the screen control rights are transferred to the target operating system through the screen driver. Of course, it can also be achieved in other ways mentioned above, which will not be described in detail here.

[0109] In the present embodiment, the screen-off display control method is applied to a mobile device capable of running at least two operating systems. When the mobile device is in a screen-off state and it is detected that the mobile device meets the screen-off display condition, the screen control of the mobile device is switched to any other operating system except the one with the highest power consumption, and the screen is displayed off under the target operating system, thereby avoiding high power consumption due to the need to refresh the screen in the operation with the highest power consumption, reducing power consumption and extending the battery life of the mobile device.

[0110] In an optional embodiment of the present application, the above-mentioned screen-off display control method further includes: when the screen control right of the mobile device belongs to the operating system with the highest power consumption among at least two operating systems, obtaining input screen-off display configuration information, the screen-off display configuration information including the state of the screen-off display function switch and the screen-off display time range; the operating system with the highest power consumption transmits the screen-off display configuration information to the target operating system. In an optional embodiment, the screen-off display configuration information may also include screen-off display content. The screen-off display content may be configured as needed, such as displaying time, weather, etc.

[0111] When the screen is controlled by a multi-functional and high-performance operating system, the configuration information input by the user is obtained, and the user's personalized configuration of the off-screen display related information is realized to meet personalized needs, ensure the stability of configuration permissions, improve security, and avoid configuration permission confusion.

[0112] In an optional embodiment of the present application, the target operating system is the operating system with the lowest power consumption among the at least two operating systems; the above-mentioned screen off display control method also includes: shutting down other operating systems among the at least two operating systems except the target operating system, or controlling other operating systems among the at least two operating systems except the target operating system to sleep.

[0113] Using the operating system with the lowest power consumption to control the screen to turn off the screen can reduce power consumption and extend the battery life of the mobile device. By shutting down other operating systems, other operating systems are prevented from consuming power in the background, further reducing power consumption.

[0114] It should be understood that although Figure 2 and Figure 5 The steps in the flowchart are shown in sequence as indicated by the arrows, but these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified in this document, there is no strict order restriction for the execution of these steps, and these steps can be executed in other orders. Moreover, Figure 2 and Figure 5At least a part of the steps in the above may include multiple sub-steps or multiple stages, and these sub-steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these sub-steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least a part of the sub-steps or stages of other steps. All possible combinations of the above embodiments belong to the scope of protection requested by this application.

[0154] For the specific definition of the off-screen display control device, please refer to the definition of the off-screen display control method above, which will not be repeated here. Each module in the above-mentioned off-screen display control device can be implemented in whole or in part by software, hardware and a combination thereof. The above-mentioned modules can be embedded in or independent of the processor in the computer device in the form of hardware, or can be stored in the memory of the computer device in the form of software, so that the processor can call and execute the operations corresponding to the above modules.

[0155] Figure 8 FIG. 1 is a block diagram of the internal structure of a screen-off display control device in another embodiment. Figure 8As shown, the screen-off display control device includes an AOD parameter configuration module 810, a system switching control module 820 and an AOD display control module 830. Among them, the AOD parameter configuration module 810 and the system switching control module 820 are located under the first operating system, and the AOD display control module 830 is located under the second operating system. The AOD parameter configuration module 810 is used to receive AOD configuration information input by the user when the first operating system controls the screen control right. The AOD configuration information includes the state of the AOD switch, the AOD time range, and the AOD interface display content. The state of the AOD switch includes the on and off state. The AOD time range includes the entry (i.e., the start time) and exit (i.e., the end time) time periods. After detecting that the mobile device turns off the screen, the system switching control module 820 reads the AOD configuration information and the current usage status saved by the AOD parameter configuration module 810, and determines whether the AOD display condition is met according to the AOD configuration information. If the AOD display condition is met, the system switching control module 820 transfers the screen control right of the mobile device to the AOD display control module 830 in the second operating system, and notifies the AOD display control module 830 in the second operating system to enter the AOD display state. After completing the above operations, the first operating system enters a dormant state to reduce the standby power consumption of the device. After the AOD display control module 830 receives the screen control right transferred by the system switching control module 820, according to the AOD interface content transmitted by the AOD parameter configuration module 810, the display of the AOD interface is started, and the AOD interface is refreshed. There are two situations for AOD display exit, one is the exit operation actively initiated by the AOD display control module 830. The AOD display control module 830 determines whether the current moment is within the AOD display time range according to the AOD display time range set by the user, and if it is not within the AOD display time range, the exit operation is actively initiated. The second is an exit operation actively initiated by the system switching control module 820 under the first operating system. When a preset event such as an incoming call event, an alarm event, or a charging event occurs, the first operating system is awakened and sends a message to the AOD display control module 830 to exit the AOD interface display, and switches the screen control to the first operating system.
