Background

The information on display (AOD) function may also be referred to as an off display or an off display function. The AOD function is a characteristic of screen display that depends on the electronic device, and when a user triggers an operation of screen display (for example, the user presses a power key), the electronic device can display screen information (such as some patterns, time, messages, and the like) on a screen that has been turned off with lower power consumption.

Rather, use of the word "exemplary" or "such as" is intended to present relevant concepts in a concrete fashion for ease of understanding.

Currently, in the AOD function, the electronic device may determine whether to display information according to the state of the user. For example, the AOD function may enable an electronic device to display information if and only if a user is looking at a screen of the electronic device. Illustratively, the AOD function is used to light a partial area of the display screen in which important information such as time, date, power, notification, etc. is displayed when the electronic device is turned off. Taking an electronic device as an example of a mobile phone, as shown in fig. 1, when a user holds the mobile phone and looks at the mobile phone screen, the mobile phone screen displays information. For example, as shown in fig. 2a, after the mobile phone enters the screen-off state, the mobile phone may display a screen-off animation corresponding to the electric quantity in the first area 10 of the screen. Also, the mobile phone may display the current time, date, power, or notification message in the second area 20. Certainly, the mobile phone may also display the identifier of the fingerprint identification in the second area 20 in the state of the information screen, and the content displayed in the second area 20 is not limited in this embodiment.

In some embodiments, the electronic device may generate dynamic or static screen-off information according to a user's travel mode, time, weather, location, height, and display the screen-off information when the user turns off the screen.

2 b-2 f are diagrams illustrating exemplary user interfaces displayed when the electronic device is in the flight mode and the electronic device is turned off after the turn-off display function is turned on.

As shown in fig. 2b, the user interface includes a picture display area 311 and an information display area 312. The picture display area 311 is used for displaying a picture generated by the electronic device according to the information of the user, such as the travel mode, the time, the weather, and the like, and the information display area 312 is used for displaying information of the time, the date, the electric quantity, the notification, and the like, wherein the picture and the information jointly form information of a screen of the electronic device. As can be seen from the picture display region 311 shown in fig. 2b, the picture display region 311 is used to simulate the view of a user looking outward through an airplane window on an airplane, thereby increasing the interest of the screen display. The outline of the picture display region 311 is the outline of an airplane window, and UI elements such as scenes, the sun, and clouds are displayed in the picture display region 311. The scenery may be a UI element selected by the electronic device according to a viewing angle of the scenery viewed on the airplane in the airplane travel mode, and the sun may be a time element determined by the electronic device when the current time is determined to be in the daytime according to the current time. Similarly, when the electronic device determines that the current time is at night according to the current time, the sun may change to moon. The cloud may be a weather element determined by the electronic device when the weather of the geographic location of the electronic device is judged to be cloudy according to the weather. Similarly, when the electronic device determines that the weather of the geographic location of the electronic device is light rain, the cloud may be changed to a raindrop.

In the user interface shown in fig. 2b, the electronic device may receive a touch operation of the user action with the picture display area 311, and in response to the operation, the electronic device displays the user interface 31 shown in fig. 2 c. At this time, the picture displayed in the picture display area 311 may be updated from fig. 2b to the content displayed in fig. 2 c.

As shown in fig. 2c, the picture displayed in the picture display area 311 is used to simulate an image that can be seen by a user when the aircraft window is closed. It can be seen that when the aircraft window is closed, no elements such as scenery, sun, cloud, etc. are displayed in the picture display area 311. When the electronic device detects again a user operation on the picture display area 311 by the user, the picture displayed in the picture display area 311 is updated to the picture displayed in the picture display area 311 in fig. 2 d.

As shown in fig. 2d, the picture displayed in the picture display region 311 contains UI elements such as scenes, sun, and clouds, and unlike fig. 2b, the scenes contained in the picture display region 311 may be different. That is, the electronic apparatus may continuously update the off-screen displayed picture, for example, when the electronic apparatus receives a user operation applied to the picture display region 311, the electronic apparatus updates the scene in the off-screen displayed picture. Therefore, the interest of screen-off display can be increased, and the screen-off display content can be enriched.

In some embodiments, the screen-out image displayed by the electronic device may also contain UI elements related to the vehicle the user is traveling on. For example, as shown in fig. 2e, in the user interface 31 displayed by the electronic device, the picture display area 311 may contain an airplane element 311A. The reason is that when the electronic device acquires that the current travel mode of the user is the airplane travel mode, the electronic device can add wing elements to the screen-off image to enrich the content of the screen-off image, and the electronic device is more suitable for the scene observed when the user browses the scenery through the airplane window in the actual airplane travel scene. Similarly, when the travel mode is a train travel mode, the train body and the like may be included in the screen-out image.

In some embodiments, the screen-out image displayed by the electronic device may also indicate the travel progress of the user. For example, as shown in fig. 2f, the user interface 31 displayed on the electronic device may further include a travel progress bar 313, where the travel progress bar 313 is used to indicate the progress of the user in the out-trip. Specifically, if the electronic device acquires that the user is in the airplane travel mode from point 8 to point 11, when the electronic device detects that the user is off the screen at point 9, since the electronic device calculates that the user has spent one third of the airplane journey, the travel progress bar 313 displayed by the electronic device may indicate that the user has spent one third of the boarding time on the airplane. Therefore, the electronic equipment can display the screen-off image related to the user trip, and simultaneously further inform the user of the trip time, and help the user to quickly know the trip condition of the user.

It should be noted that, in the above embodiments, the user interfaces shown in fig. 2a to fig. 2f are all illustrated by taking an electronic device as a mobile phone as an example. Of course, the electronic device may also be other suitable devices (such as a tablet computer, a smart watch, and the like), which is not limited in this application.

In some embodiments, the AOD function enables dynamic display of information on a screen via Always On (AON) technology. Specifically, the AON technology needs to detect whether there is a user image (e.g., user face information) in real time while the AP (application processor) side is asleep. When the electronic equipment detects that a user image exists, the electronic equipment enters a screen-off state and displays screen-off information; when the electronic device does not detect the user image, the electronic device enters a black screen state. However, in this solution, the electronic device is required to collect the ambient light brightness in real time, which inevitably increases the power consumption of the electronic device, and further affects the performance and the lifetime of the electronic device.

Based on this, an embodiment of the present application provides an information screen display method, where the method is capable of identifying scene information (such as ambient light brightness and posture information) of a scene where an electronic device is currently located, and when the scene information meets a preset condition, the electronic device detects whether there is a user image. If the electronic equipment detects the user image, the electronic equipment displays screen information, so that the screen information displaying time can be effectively shortened, and the power consumption of the equipment is further reduced.

Illustratively, the electronic device detecting whether there is a user image includes: the electronic device first collects the ambient light brightness through the camera and takes a low power picture (such as a low power picture) based on the ambient light brightness. And then, the electronic equipment detects whether the picture contains the user image or not according to the collected low-power-consumption picture. In addition, when the electronic device performs the information display, a part of pixels in the display screen of the electronic device are lighted up, so that the electronic device can display the information display with low power consumption.

The preset conditions comprise a first preset condition and a second preset condition. The first preset condition includes that the ambient light brightness is within a first preset range (or called a first interval); the second preset condition includes that an included angle between a screen of the electronic device and a horizontal plane is within a second preset range (or called a second interval). In some embodiments, the preset condition further includes that the electronic device is in a static state, and for example, the first preset range may be, for example, 200nits to 600 nits. The second preset range may be, for example, 30 ° to 180 °. In some embodiments, the second preset range may also be referred to as a screen of the electronic device facing up or in an elevation state.

It should be noted that the above embodiments are merely illustrative of the first preset range and the second preset range, and do not limit the present application. The first preset range and the second preset range may also be other suitable ranges, and are not limited in this embodiment of the application, specifically based on actual settings.

For example, the information screen display method provided in the embodiment of the present application may be applied to electronic devices such as a mobile phone, a tablet computer, a Personal Computer (PC), a Personal Digital Assistant (PDA), a smart watch, a netbook, a wearable electronic device, an Augmented Reality (AR) device, a Virtual Reality (VR) device, an in-vehicle device, an intelligent automobile, and an intelligent audio device, and the embodiment of the present application does not limit the scope of the present application.

In some embodiments, the sensor module 180 may be a sensor hub; the acceleration sensor 180E and the gravity sensor 180N may also be collectively referred to as an attitude sensor, and are configured to acquire an attitude of the electronic device (e.g., a static or moving state of the electronic device, an angle between a display screen of the electronic device and a horizontal plane, and the like). In the embodiment of the present application, the acceleration sensor 180E and the gravity sensor 180N may also be referred to as a + G devices.

In some embodiments, the ambient light sensor 180L is used to obtain environmental information (e.g., ambient light level); the acceleration sensor 180E and the gravity sensor 180N are used to obtain posture information (such as a static state or a moving state, an included angle between a display screen of the electronic device and a horizontal plane, and the like) of the electronic device. In addition, in the embodiment of the present application, an AON control module may be further disposed in the sensor module 180. The AON control module is used for controlling the AON function, and the AON function is used for detecting the user image. For example, the AON control module is used to turn AON functions on or off. When the AON control module starts the AON function, the electronic device 100 detects whether there is a user image; when the AON control module turns off the AON function, the electronic device 100 does not detect the user image, nor turns on the information screen display function. I.e. the electronic device 100 is in a black screen state.

It is to be understood that the illustrated structure of the present embodiment does not constitute a specific limitation to the electronic apparatus 100. In other embodiments, electronic device 100 may include more or fewer components than shown, or combine certain components, or split certain components, or a different arrangement of components.

Illustratively, in the embodiment of the present application, an AON module may be disposed in the application processor. The AON module is used for detecting a user image. For example, when the AON module detects a user image, the electronic device 100 turns on a message screen display function; when the AON module does not detect the user image, the electronic device 100 does not turn on the information display function, that is, the electronic device 100 is in a black screen state.

The controller may be a neural center and a command center of the electronic device 100. The controller can generate an operation control signal according to the instruction operation code and the timing signal to complete the control of instruction fetching and instruction execution.

A memory may also be provided in processor 110 for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. The memory may hold instructions or data that have just been used or recycled by the processor 110. If the processor 110 needs to reuse the instruction or data, it can be called directly from the memory.

With reference to the electronic device 100 shown in fig. 3, as shown in fig. 4, a composition diagram of an electronic device 100 provided in the embodiment of the present application is shown. As shown in fig. 4, the electronic device 100 includes an AON control module, an ambient light module, an attitude sensor module (or referred to as an a + G module), and an AON module. Wherein, the AON module is arranged at the side of the application processor (namely the AP side); (ii) a The AON control module, the environment light module and the attitude sensor module are arranged at a sensing concentrator end (namely a sensor hub end). In some embodiments, the ambient light module may be, for example, the ambient light sensor 180L in the above embodiments. The attitude sensor module may include, for example, the acceleration sensor 180E and the gravity sensor 180N in the above-described embodiments.

Illustratively, the ambient light module is configured to collect brightness of current ambient light, and send (or transfer) the current ambient light brightness to the AON control module. The attitude sensor module is used for acquiring the attitude information of the current electronic equipment and sending (or transmitting) the attitude information to the AON control module. The posture information is used for indicating an included angle between a display screen of the electronic device and a horizontal plane and a state (such as a static state or a motion state) of the electronic device. On the basis, after the AON control module receives the ambient light brightness sent by the ambient light module and the attitude information sent by the attitude sensor module; the AON control module judges whether the environmental light brightness and the posture information meet preset conditions. If the environmental light brightness and the posture information meet preset conditions, the AON control module controls the AON module to be started; and if the environmental light brightness and the posture information do not meet the preset conditions, the AON control module controls the AON module to be closed.

It is understood that the AON module may be used to detect the user image after the AON module is turned on. When the AON module detects a user image, the electronic equipment enters a screen-off state and displays screen-off information; when the AON function does not detect the user image, the electronic apparatus does not display information (e.g., the electronic apparatus enters a black screen state).

In addition, if the ambient light brightness and the posture information do not meet the preset conditions, the AON module is closed, and at the moment, the electronic equipment does not start the screen displaying function, namely, the electronic equipment does not display the screen displaying information.

The electronic device may detect the user image, for example, the electronic device may detect the user image through a camera. Based on this, when the AON module is opened, the AON module can be used for starting the camera to make electronic equipment pass through the camera and detect user's image.

In the above embodiment, the preset condition includes that the ambient light brightness is within a first preset range; the electronic equipment is in a static state, and an included angle between a screen of the electronic equipment and a horizontal plane is within a second preset range. The second preset range may be, for example, 30 ° to 180 °. When the included angle between the screen of the electronic device and the horizontal plane is 30-180 degrees, the user can see the screen of the electronic device when watching the front. At this time, the camera of the electronic device can acquire the user image. And when the included angle between the electronic screen and the horizontal plane is 0-30 degrees, the user can not see the screen of the electronic equipment when watching the front. At this time, the camera of the electronic device cannot acquire the user image.

Taking an electronic device as a mobile phone as an example, as shown in fig. 5a, an angle between a screen of the mobile phone and a horizontal plane is 180 °. When the included angle between the screen of the mobile phone and the horizontal plane is 180 degrees, the front of the screen of the mobile phone is upward.

For another example, as shown in fig. 5b, the screen of the mobile phone forms an angle of 90 ° with the horizontal plane. When the included angle between the screen of the mobile phone and the horizontal plane is 90 degrees, the screen of the mobile phone is opposite to the face of the user, namely, the eyes of the user can directly look at the screen of the mobile phone.

For another example, as shown in fig. 5c, the screen of the mobile phone has an angle of 30 ° with the horizontal plane. When the angle between the screen of the mobile phone and the horizontal plane is 30 degrees, the user can hardly see the screen of the mobile phone directly.

For another example, as shown in fig. 5d, the screen of the mobile phone has an angle of 0 ° with the horizontal plane. When the included angle between the screen of the mobile phone and the horizontal plane is 0 degree, the screen of the mobile phone is completely buckled on the horizontal plane, and at the moment, the user cannot see the screen of the mobile phone.

In some embodiments, the software system of the electronic device 100 may employ a hierarchical architecture, an event-driven architecture, a microkernel architecture, a microservice architecture, or a cloud architecture. The embodiment of the present invention exemplarily illustrates a software architecture of the electronic device 100 by taking an Android system with a layered architecture as an example.

Fig. 6 is a block diagram of a software structure of the electronic device 100 according to an embodiment of the present disclosure.

It will be appreciated that the hierarchical architecture divides the software into several layers, each layer having a clear role and division of labor. The layers communicate with each other through a software interface. In some embodiments, the Android system may include an application layer (APP), an application framework layer (FWK), a Hardware Abstraction Layer (HAL), and a kernel layer (kernel). In some embodiments, fig. 6 also illustrates a hardware structure (e.g., a display screen) of the electronic device.

Illustratively, as shown in fig. 6, the application layer may include APP1, APP2, APPN. The application framework layer provides an Application Programming Interface (API) and a programming service for an application of the application layer. The application framework layer includes a number of predefined functions. In some embodiments, as shown in FIG. 6, the application framework layer includes a message screen display service (or AOD service). The screen displaying service is used for responding to a screen event and triggering a screen event instruction (or called a face event subscription instruction). The screen-off event may be, for example, an operation of the electronic device 100 pressing a power key while the screen is on. Alternatively, the screen-off event may be, for example, an event that the electronic apparatus 100 does not detect a user operation for a certain time while the screen is on.

The hardware abstraction layer is an interface layer located between the kernel layer and the hardware, and can be used for abstracting the hardware. In some embodiments, a hardware abstraction layer interface definition language (HIDL) is further included between the application layer framework layer and the hardware abstraction layer. HIDL is the interface between the application layer framework layer and the hardware abstraction layer implementation. Illustratively, a rest screen display service in the application framework layer may call the HIDL interface to send a rest screen instruction to the hardware abstraction layer. Then, the hardware abstraction layer calls a sensor execution environment (SSE) interface to send the information screen command to the kernel layer.

The kernel layer provides underlying drivers for various hardware of the electronic device. Illustratively, as shown in fig. 6, the kernel layer includes an AON control module, an ambient light module, an attitude sensor module, and an AON module. The environment light module is used for collecting the current environment light brightness; the attitude sensor module is used for acquiring attitude information of the electronic equipment; the AON control module is used for controlling the AON module to be opened or closed according to the ambient light brightness and the posture information. For example, the AON module is used to detect user images. Illustratively, the hardware abstraction layer calls an SSE interface to send a message screen instruction to an AON control module of the kernel layer; and then, the AON control module receives the screen information instruction, acquires the current environment light brightness and the posture information and determines whether the current environment light brightness and the posture information meet preset conditions. If the current ambient light brightness and the current attitude information meet preset conditions, the AON control module controls the AON module to be started; and if the current ambient light brightness and the current attitude information do not meet the preset conditions, the AON control module returns the first information to the information screen display service. The first information is used for informing the information screen that the current ambient light brightness and the posture information of the display service do not meet preset conditions.

In some embodiments, the screen-off event may periodically trigger the screen-off command, that is, the AON control module may periodically receive the screen-off command. On this basis, after the message screen display service receives the first information, the message screen display service does not send a message screen instruction to the AON control module any more, that is, the message screen display function is turned off.

Illustratively, the AON control module calls an SSE interface to return the first information to the hardware abstraction layer; and then, calling the HIDL interface by the hardware abstraction layer to return the first information to the message screen display service.

Under the condition that the current ambient light brightness and the current attitude information meet the preset conditions, the AON control module controls the AON module to be opened, and the AON module starts to detect whether user images exist. If the AON module detects that a user image exists, the electronic equipment enters a screen-off state and displays screen-off information; and if the AON module does not detect the user image, the electronic equipment does not display information of the screen.

In some embodiments, the environment light module is further configured to report the brightness of the environment light to the AON control module; the attitude sensor module is also used for reporting attitude information to the AON control module. And then, the AON control module determines whether the environmental light brightness and the posture information meet preset conditions according to the environmental light brightness reported by the environmental light module and the posture information reported by the posture sensor module. If the environmental light brightness and the posture information meet the preset conditions, the AON module continues to detect whether a user image exists; and if the environmental light brightness and the posture information do not meet the preset conditions, the AON control module controls the AON module to be closed. Then, the AON module cannot detect the user image, and the electronic device will not display information.

It should be noted that, when the AON module detects whether there is a user image, the camera needs to be started for detection, so in this embodiment of the application, when the AON module is started, that is, the AON module controls the camera to detect whether there is a user image; when the AON module is turned off, the AON module turns off the camera.

Next, a screen display method according to an embodiment of the present application will be described with reference to the electronic device shown in fig. 6 as an example. Illustratively, as shown in conjunction with fig. 6 and 7, the message screen display method includes steps a 1-a 10.

Step A1, the electronic device registers the interface through the AON control module and the environment light module.

Exemplarily, the AON control module sends a registration request message to the ambient light module; the registration request message is used for indicating the identification information of the AON control module. Then, the environment optical module replies a response message to the AON control module; the response message is used to indicate identification information of the ambient light module. The AON control module and the environment optical module register an interface according to the registration request message and the response message, so that the AON control module can call the interface to access the environment optical module; the environment light module can call the interface to access the AON control module.

And step A2, the electronic equipment registers an interface through the AON control module and the attitude sensor module.

Illustratively, the AON control module sends a registration request message to the attitude sensor module; the registration request message is used for indicating the identification information of the AON control module. Then, the attitude sensor module replies a response message to the AON control module; the response message is used to indicate identification information of the attitude sensor module. The AON control module and the attitude sensor module register an interface according to the registration request message and the response message, so that the AON control module can call the interface to access the attitude sensor module; the attitude sensor module can also call the interface to access the AON control module.

Step A3, the electronic device registers the interface through the AON control module and the AON module.

Illustratively, the AON control module sends a registration request message to the AON module; the registration request message is used for indicating the identification information of the AON control module. Then, the AON module replies a response message to the AON control module; the response message is used to indicate the identification information of the AON module. The AON control module and the AON module register an interface according to the registration request message and the response message, so that the AON control module can call the interface to access the AON module; the AON module can call the interface to access the AON control module.

It should be noted that, the electronic device may perform step a 1-step A3 at the same time; or the electronic device may perform step a1, then perform step a2, and finally perform step A3, where the sequence of step a1 to step A3 is not limited in this embodiment of the application.

In addition, in steps a1 to A3, the interface may be registered when the electronic device is powered on, or may be registered when the electronic device is shipped from a factory, which is not limited in this embodiment of the present application. The registration interface when the electronic device is powered on may be a registration interface when the electronic device is powered on for the first time, or may be a registration interface when the electronic device is powered on each time.

Step A4, the electronic device receives the screen-playing instruction through the AON control module.

Illustratively, as described in connection with FIG. 6, the screenshot display service triggers a screenshot command in response to a screenshot event. And then, the information screen display service calls the HIDL interface to send the information screen command to the hardware abstraction layer, and the hardware abstraction layer calls the SSE interface to send the information screen command to the AON control module.

And A5, the electronic equipment acquires the ambient light brightness through the AON control module according to the information screen instruction.

For example, the AON control module obtains the ambient light level from the ambient light module.

And A6, the electronic equipment acquires the attitude information through the AON control module according to the information screen instruction.

For example, the AON control module acquires pose information to a pose sensor module. The posture information is used to indicate a state (such as a static state or a motion state) of the electronic device and an angle between a screen (or called a display screen) of the electronic device and a horizontal plane.

It should be noted that, the electronic device may perform step a5 and step a6 at the same time; or the electronic device may perform step a5 first and then perform step a6, and the steps of step a5 and step a6 are not limited in this embodiment of the application.

And step A7, the electronic equipment determines that the ambient light brightness and the posture information meet preset conditions through the AON control module, and executes step A8.

The preset conditions include that the ambient light brightness is within a first preset range (e.g., 200nits to 600nits), the electronic device is in a static state, and an included angle between a screen of the electronic device and a horizontal plane is within a second preset range (e.g., 30 to 180 °).

Step A8, the electronic device opens the AON module through the AON control module.

Illustratively, when the AON control module determines that the ambient light brightness and the posture information satisfy the preset conditions, the AON control module controls the AON module to be turned on, and the AON module starts to detect whether there is a user image. If the AON module detects the user image, the electronic equipment enters a screen-off state and displays screen-off information; and if the AON module does not detect the user image, the electronic equipment does not display information of the screen.

And step A9, the electronic equipment determines that the ambient light brightness and the posture information do not meet the preset conditions through the AON control module, and executes step A10.

Step A10, the electronic device returns the first information through the AON control module.

Illustratively, as shown in connection with FIG. 6, the AON control module returns the first information to the message screen display service. The first information is used for informing the information screen that the current ambient light brightness and the posture information of the display service do not meet preset conditions. And then, after receiving the first information, the information screen display service does not send an information screen instruction to the AON control module. That is, the electronic device turns off the message screen display function.

And A11, the electronic equipment reports the ambient light brightness to the AON control module through the ambient light module.

And A12, the electronic equipment reports the attitude information to the AON control module through the attitude sensor module.

In some embodiments, when the electronic device changes from a static state to a moving state (e.g., the electronic device is lifted by a user or moved by a user), the ambient light module reports the ambient light brightness to the AON control module, and the gesture sensor module reports the gesture information to the AON control module. In other embodiments, the ambient light module reports the ambient light brightness to the AON control module within a period of time, and the attitude sensor module reports the attitude information to the AON control module within the period of time.

It should be noted that the period duration may be, for example, 30s, 1min, or another suitable period duration, and the period duration is not limited in the embodiment of the present application. In addition, the electronic device may perform step A8 and step a9 simultaneously; alternatively, the electronic device may perform step A8 first and then perform step a9, where the sequence of step A8 and step a9 is not limited in this embodiment of the application.

And step A13, the electronic equipment confirms that the ambient light brightness and the posture information do not meet the preset conditions through the AON control module, and executes step A14.

It should be noted that, for the illustration of the preset condition, reference may be made to the foregoing embodiments, and details are not described herein.

Step A14, the electronic device turns off the AON module through the AON control module.

Illustratively, when the AON control module determines that the ambient light brightness and the posture information do not satisfy the preset conditions, the AON control module turns off the AON module. In addition, when the AON control module confirms that the environmental light brightness and the posture information meet the preset conditions, the AON module continues to detect whether the user image exists.

In some embodiments, the period duration is a set period duration for the first time; on the basis, when the AON control module confirms that the environmental light brightness and the posture information do not meet the preset conditions in the period duration of the set second time, the AON control module closes the AON module. Or; and when the AON control module confirms that the environmental light brightness and the posture information do not meet the preset conditions in the period duration of which the period duration is the set contact duration for N times, the AON control module closes the AON module. Wherein N is more than 1.

It can be appreciated that when the AON module is turned off, the AON module cannot detect the user image and the electronic device does not display information.

In the embodiment of the application, the electronic device recognizes the current ambient light brightness and the posture information of the electronic device, and the electronic device starts to detect the user image when the ambient light brightness and the posture information meet the preset conditions. If the electronic equipment detects the user image, the electronic equipment displays screen information, so that the screen display time can be effectively shortened, and the power consumption of the equipment is reduced.

In some embodiments, when the electronic device confirms that the ambient light brightness and the posture information satisfy the preset conditions and the electronic device detects the user image, a display screen of the electronic device displays prompt information. The prompt information is used for prompting whether to enter a screen-off state or not to a user. Illustratively, as shown in fig. 8, the prompt message 30 displayed on the display screen of the electronic device may be, for example, "whether to enter the screen saver state". If the user clicks the "confirm" control, the display screen of the electronic device displays screen-turning information (the screen-turning information shown in fig. 2 in the above embodiment); and if the user clicks the 'cancel' control, the electronic equipment does not display screen-turning information.

In the embodiment, when the electronic equipment confirms that the ambient light brightness and the posture information meet the preset conditions and the electronic equipment detects the user image, a display screen of the electronic equipment displays prompt information; because the prompt message is used for prompting the user whether to enter the screen-off state, the user can select whether to enter the screen-off state according to the prompt message, and the user experience is improved.

In some embodiments, as shown in fig. 9, a flowchart of a method for displaying a message screen provided in an embodiment of the present application is shown. Referring to fig. 9, the screen display method includes S201 to S204.

S201, the electronic equipment receives a screen turning-off event.

And the screen turning event is used for starting a screen turning display function. Illustratively, the screen-off event may be, for example, an operation of the electronic device that the user presses a power key while the screen is on. Alternatively, the screen-off event may be, for example, an event that the electronic device does not detect a user operation for a certain time while the electronic device is on the screen.

S202, the electronic equipment responds to the screen-turning event and obtains target parameters.

Wherein the target parameters at least include an ambient light level and a direction of a display screen of the electronic device.

For example, the display screen of the electronic device may be oriented at an angle to the horizontal plane.

In some embodiments, the target parameters also include a distance between a display screen of the electronic device and a face of the user (e.g., an ear of the user or a face of the user), a current time, and a state of the electronic device (e.g., a stationary state or a moving state).

And S203, when the target parameter meets a preset condition, starting the camera by the electronic equipment.

The preset conditions comprise a first preset condition and a second preset condition. The first preset condition is that the ambient light brightness is within a first interval (or called a first preset range); the second preset condition includes that the direction of the display screen of the electronic device (i.e., the included angle between the display screen of the electronic device and the horizontal plane) is within a second interval (or called a second preset range).

Illustratively, the first interval may be, for example, 200nits to 600nits, or [200cd/m [ ]²，600cd/m²](ii) a The second interval may be, for example, 30 ° to 180 °, or [30 °, 180 ° ]]。

The above is merely an example of the first interval and the second interval, and does not limit the present application. The first interval and the second interval may also be other suitable ranges, and are specifically set as the standard, which is not limited in the embodiments of the present application.

In some embodiments, the preset conditions further include that a distance between a display screen of the electronic device and the face of the user is greater than a preset value, a current time is within a preset time period, and a state of the electronic device is a stationary state.

Illustratively, the preset value may be, for example, 10 cm; the preset time period may be, for example, 6:00 to 2:00(24 hours). In some embodiments, the preset time period may be, for example, a fixed time period. For example, the time period preset by the electronic device at the time of factory shipment, or the time period set by the user in the "setting application" of the electronic device. In other embodiments, the preset time period may be a dynamically changing time period, for example. For example, the electronic device may determine the preset time period according to historical data of the user using the electronic device within a certain time period (e.g., a week or a month). For example, a user often uses the electronic device at 8:00-22:00(24 hours system) for a certain period of a week, and thus 8:00-22:00 may be set to a preset time period. For another example, the user often uses the electronic device at 10:00-00:00 (24-hour system) during the next one-week period, and thus 10:00-00:00 can be set to the preset time period.

It should be noted that the foregoing is only an example of the preset value and the preset time period, and does not limit the application, and the specific setting is subject to the standard.

And S204, when the electronic equipment detects the user image through the camera, displaying a screen displaying interface.

The screen turning interface is used for displaying screen turning information.

It can be understood that when the target parameter satisfies the preset condition, the electronic device starts the camera to detect whether there is a user image. When the electronic equipment detects the user image through the camera, a screen-switching interface is displayed, and screen-switching information is displayed on the screen-switching interface.

With reference to the foregoing embodiments, it should be noted that, since the preset value is 10cm, if the distance between the display screen of the electronic device and the face of the user is smaller than or equal to the preset value, it indicates that the display screen of the electronic device is close to the face of the user (for example, the user is making a call with the electronic device being held by the user, or the user is close to the face with the electronic device being held by the user). In this case, although the ambient light brightness is in the first interval, and the included angle between the display screen of the electronic device and the horizontal plane is in the second interval, since the display screen of the electronic device is close to the user's face, the user cannot see even if the electronic device displays information on the screen, so that the electronic device needs to determine whether the distance between the display screen of the electronic device and the user's face is greater than the preset value in the case that the ambient light brightness is in the first interval and the included angle between the display screen of the electronic device and the horizontal plane is in the second interval.

In addition, it should be noted that, since the preset time period is 6:00-2:00(24 hours), if the current time is not within the preset time period, it indicates that the current time is in the evening (for example, two points in the morning to six points in the morning), most users will not use the mobile phone at this time, and therefore, the message screen display is not needed. In this case, although the ambient light brightness is in the first interval, and the included angle between the display screen of the electronic device and the horizontal plane is in the second interval, since the current time is in the evening, even if the electronic device displays information, the user may not see the information at rest, and therefore, in the case that the ambient light brightness is in the first interval and the included angle between the display screen of the electronic device and the horizontal plane is in the second interval, the electronic device needs to determine whether the current time is within the preset time period.

In some embodiments, the electronic device does not display information when the electronic device does not detect a user image through the camera.

In the embodiment of the application, when the electronic equipment receives a screen turn-off event, the electronic equipment responds to the screen turn-off event and acquires a target parameter; when the target parameter meets the preset condition, namely the ambient light brightness is in the first interval, the direction of the display screen of the electronic equipment is in the second interval, the electronic equipment starts the camera and detects whether a user image exists through the camera, when the electronic equipment detects the user image, the electronic equipment displays the screen-off interface and displays screen-off information on the screen-off interface, and therefore the time for displaying the screen-off interface can be effectively shortened, and the power consumption of the equipment is further reduced.

An embodiment of the present application provides an electronic device, which may include: a display screen (e.g., a touch screen), memory, and one or more processors. The display screen, memory and processor are coupled. The memory is for storing computer program code comprising computer instructions. When the processor executes the computer instructions, the electronic device may perform various functions or steps performed by the mobile phone in the above-described method embodiments. The structure of the electronic device may refer to the structure of the electronic device 100 shown in fig. 3.

The embodiment of the present application further provides a chip system, as shown in fig. 10, the chip system 1800 includes at least one processor 1801 and at least one interface circuit 1802. The processor 1801 may be the processor 110 shown in fig. 3 in the foregoing embodiment. The interface circuit 1802 may be, for example, an interface circuit between the processor 110 and the external memory 120; or an interface circuit between the processor 110 and the internal memory 121.

The processor 1801 and the interface circuit 1802 may be interconnected by wires.
