Description

Screen-off display method and electronic equipment

Technical Field

The application relates to the field of terminal display, in particular to a screen-off display method and electronic equipment.

Background

With the development of electronic technology, electronic devices are becoming more and more diversified. Currently, the market for folding screen devices is increasing. The folding screen device refers to an electronic device with a folding screen. Taking a folding screen mobile phone as an example, a display screen can be displayed through a bright screen when a user uses the folding screen mobile phone, so that a display function is provided for the user. When the user does not need to use the folding screen mobile phone, the display screen can automatically enter a screen-off (or screen-off) state under the operation of the user or after a preset time length so as to save the power consumption of the mobile phone.

At present, the brightness of the screen display after screen extinction can be adaptively adjusted according to the ambient light brightness. Taking an external folding screen mobile phone as an example, a photosensitive element on a display screen is usually arranged on a main screen, and the display brightness of the secondary screen off-screen display is adjusted through the ambient light information sensed by the photosensitive element on the main screen. In some scenes, if the external folding screen mobile phone is in a folded state and the auxiliary screen of the display screen is placed upwards, the auxiliary screen of the display screen cannot sense the information of the ambient light brightness, so that the external folding screen mobile phone cannot adaptively adjust the display brightness of the off screen. In other words, in the related art, the screen-off scheme is not intelligent enough, which may cause waste of power consumption.

Disclosure of Invention

The application provides a screen-off display method and electronic equipment, which solve the problems that a screen-off scheme in the prior art is not intelligent enough and power consumption waste is easy to cause.

In order to achieve the above purpose, the application adopts the following technical scheme:

In a first aspect, a method for displaying a screen in a screen quenching manner is provided, and the method is applied to an electronic device, wherein the electronic device is provided with a folding screen, the folding screen comprises a main screen and a secondary screen, and the folding screen is in a folded state, and the method comprises:

When the display state of the folding screen is monitored to be switched from bright screen display to off screen display, acquiring first display brightness and first moment, wherein the first display brightness is the display brightness of the bright screen display of the main screen before off screen, and the first moment is the off screen moment;

Determining second display brightness according to the first display brightness and the first time, wherein the second display brightness represents display brightness of the auxiliary screen off display;

And controlling the auxiliary screen to display according to the second display brightness.

In the embodiment of the application, the main screen can also be called an inner screen, and the auxiliary screen can also be called a back screen, an auxiliary screen, an outer screen and the like.

Taking an external folding screen mobile phone as an example, when the included angle between the main screen and the auxiliary screen is 180 degrees, the folding screen mobile phone is in an unfolding state (or called a full unfolding state). When the included angle between the main screen and the auxiliary screen is larger than 180 degrees and smaller than 270 degrees, the folding screen mobile phone is in a semi-folding state (or called a bracket state, a desk calendar state and the like). When the included angle between the main screen and the auxiliary screen is equal to 270 degrees, the folding screen mobile phone is in a folding state (or a fully folding state, etc.).

It should be noted that the main screen and the auxiliary screen may display one display interface together, or may display different display interfaces respectively.

In some implementations, the off-screen display application of the application layer registers for listening with a power management service module of the application framework layer; when the display state of the folding screen is switched from bright screen display to off screen display, the power management service module responds to the change of the display state of the screen, and notifies the display state of the current screen of the off screen display application by using a callback function, and pulls up the off screen display application. After the off-screen display application is pulled up, the off-screen display application obtains first display brightness and first time from the device state management service module of the application program framework layer.

In some implementations, the off-screen display application may issue an instruction to the folding screen management server module of the application framework layer to off-screen display, where the instruction may include a second display brightness; the instruction can be processed through the folding screen management service module, and the instruction is downwards transmitted to the auxiliary screen by calling the display driver in the kernel layer, so that the auxiliary screen is displayed in a second display brightness in a screen-off mode.

In the embodiment of the application, the display brightness and the time stamp (screen-off time) of the main screen bright screen display before screen off are comprehensively considered, and the correct environment light information of the current environment of the mobile phone can be accurately obtained, so that the auxiliary screen off display brightness is adaptively adjusted according to the correct environment light information, the use of a user is not influenced, and the unnecessary power consumption expenditure of screen display is saved.

In an implementation manner of the first aspect, the determining, according to the first display brightness and the first time, a second display brightness includes:

If the first moment is in the first time interval, determining the second display brightness as a first preset value;

and if the first moment is not in the first time interval, determining second display brightness according to the first display brightness and the first moment.

In some implementations, the display brightness of the display screen may include several options that are preset. For example, the display luminance includes a low-grade and a high-grade, wherein the display luminance of the high-grade is higher than that of the low-grade, and the values of the display luminances of the low-grade and the high-grade, respectively, are fixed. In this implementation, the display brightness of the display screen is switched between the high and low levels.

In other implementations, the display brightness of the display screen may include any value within a predetermined range. In this implementation, the display brightness of the display screen is switched within a preset range.

In general, the frequency of using the mobile phone by most users in the first time interval (such as daytime or 07:00-22:00) in a day is high, and the brightness of the environment in the time interval is relatively high, so that the display brightness of the secondary screen off display in the time interval is set to a first preset value, which is more in accordance with the use habit of most users. And the difference of the use habits of different users in the second time interval (such as night or 22:00-07:00) is larger, so that the display brightness of the secondary screen off display is determined according to the first display brightness and the first time in the second time interval, which is equivalent to the targeted setting for different users, has stronger adaptability and is beneficial to improving the user experience.

Detecting whether the first display brightness is effective or not according to the first moment;

if the first display brightness is effective, determining the second display brightness according to the first display brightness;

And if the first display brightness is invalid, determining the second display brightness according to the screen gesture of the electronic equipment.

In some implementations, determining the second display brightness according to the first display brightness may be setting the second display brightness to the first display brightness, that is, setting the display brightness of the sub-screen off-screen display to the display brightness of the main screen bright-screen display before off-screen.

In the embodiment of the application, the screen gesture can refer to the relative position of the main screen and the auxiliary screen. For example, when the external folding screen mobile phone is in a folded state, the screen gesture may be that the main screen is upward, the auxiliary screen is downward, the main screen is downward, the auxiliary screen is upward, and so on. Here, upward and downward are relative terms, and for example, downward may refer to the same direction as gravity, and upward may refer to the opposite direction to gravity.

In an implementation manner of the first aspect, the detecting whether the first display brightness is valid according to the first time includes:

If the time interval between the first time and the current time is smaller than a first preset duration, judging that the first display brightness is effective;

And if the time interval between the first time and the current time is greater than a first preset duration, judging that the first display brightness is invalid.

In the embodiment of the application, before determining the second display brightness, whether the first display brightness is effective is detected according to the first time. By the mode, under the condition that the brightness of the environment light changes greatly after the screen is turned off for a period of time, the screen-off display brightness can be adjusted in a self-adaptive mode, the condition that the high screen-off display brightness is always maintained is effectively reduced, the use requirement of a user is met, and meanwhile, the power consumption of the mobile phone is saved.

If the first display brightness is invalid, which means that a longer time is elapsed from the moment of screen extinction at the moment, the screen gesture may change during the time interval, for example, the main screen is turned upwards to the main screen downwards, or the main screen is turned downwards to the main screen upwards, and the different gestures of the screen affect the perception of the ambient light brightness by the photosensitive element, so as to affect the determination of the brightness of the secondary screen extinction display. Based on the above, under the condition that the first display brightness is invalid, the brightness of the secondary screen off display is determined according to the screen gesture of the electronic equipment, so that the brightness of the secondary screen off display can be effectively and adaptively adjusted, the secondary screen off display is closer to the use environment of a user, and the user experience is improved.

In an implementation manner of the first aspect, the determining the second display brightness according to the screen gesture of the electronic device includes:

And setting the second display brightness to a second preset value under the condition that the current screen posture of the electronic equipment is that the auxiliary screen is upward.

In some implementations, the first preset value and the second preset value may be the same. For example, if the first preset value is the brightness corresponding to the high-grade, if the first moment is in the first time interval, the second display brightness is set as the brightness corresponding to the high-grade; if the first time is not in the first time interval, setting the second display brightness to be the brightness corresponding to the high-grade under the condition that the current screen posture of the electronic equipment is that the auxiliary screen is upward.

In an implementation manner of the first aspect, the determining the second display brightness according to the first display brightness and the screen gesture of the electronic device includes:

Monitoring the screen gesture of the electronic equipment under the condition that the current screen gesture of the electronic equipment is that a main screen faces upwards;

When the screen gesture of the electronic equipment is switched from a main screen to a sub-screen, acquiring first brightness data, wherein the first brightness data comprises display brightness of main screen off-screen display corresponding to N times before a second time, and the second time is when the screen gesture of the electronic equipment is switched to the sub-screen;

and determining the second display brightness according to the first brightness data.

It should be noted that, in some implementations, the first luminance data may also include the second time and the display luminance of the main screen off display corresponding to each of N times before the second time. It will be appreciated that such implementations are also within the scope of embodiments of the present application.

In some implementations, when the screen gesture of the electronic device is that the main screen is upward, the light sensing sensor module of the hardware abstraction layer can monitor the ambient light brightness in real time and report the ambient light brightness to the device state management service module of the application framework layer; and the equipment state management service module calculates the display brightness of the main screen extinguishing display according to the ambient light brightness, records the time stamp and stores the display brightness and the corresponding time stamp as brightness data. The screen-off display application monitors that the screen gesture of the electronic equipment is switched from a main screen to a secondary screen, and requests information to the equipment state management service module; correspondingly, after receiving the request information, the equipment state management service module returns the current brightness data to the off-screen display application. In other implementations, the device state management service module may also report the luminance data to the off-screen display application in real time, where the luminance data is stored by the off-screen display application.

In some implementations, the off-screen display application may obtain, through the device state management service module, gesture data detected by the gesture sensor service module in the hardware abstraction layer, and determine a current screen state of the electronic device according to the gesture data. For example, the gesture data may include vertical acceleration. When the vertical acceleration is opposite to the gravity direction, judging that the main screen faces downwards and the auxiliary screen faces upwards; and when the vertical acceleration is the same as the gravity direction, judging that the main screen is upward and the auxiliary screen is downward. It should be noted that, the above is an example of judging the screen state according to the gesture data, and other sensor data may be used to judge the screen state, for example, the gesture angle, which is not limited in particular in the embodiment of the present application.

According to the embodiment of the application, the brightness of the secondary screen off display is determined according to the screen gesture of the electronic equipment, in this way, under the condition that the screen is turned over after off, the brightness of the secondary screen off display can be adjusted in a self-adaptive manner, the occurrence of the condition that the secondary screen off display brightness is lower is effectively reduced, and the user experience is improved.

In an implementation manner of the first aspect, the determining the second display brightness according to the first brightness data includes:

sequentially comparing the display brightness in the first brightness data with third display brightness according to the reverse time sequence, wherein the third display brightness is the last display brightness in the first brightness data in time sequence;

And when fourth display brightness different from the third display brightness is detected for the first time, determining the second display brightness according to the second time and a third time corresponding to the fourth display brightness.

In an implementation manner of the first aspect, the determining the second display brightness according to the second time and a third time corresponding to the fourth display brightness includes:

If the time interval between the second time and the third time is smaller than a second preset duration, determining the second display brightness according to the fourth display brightness;

And if the time interval between the second time and the third time is greater than or equal to a second preset duration, determining the second display brightness according to the third display brightness.

In an implementation manner of the first aspect, after comparing, in reverse order in time, display luminance in the first luminance data with third display luminance in sequence, the method further includes:

And if fourth display brightness different from the third display brightness is not detected, determining the second display brightness according to the third display brightness.

In some cases, the display brightness of the main screen is not necessarily updated when the screen gesture is switched to the sub-screen upward, and thus, the display brightness corresponding to the previous time of the second time may be compared with the display brightness as a reference.

In the embodiment of the application, the first brightness data can reflect the change condition of the brightness of the main screen off display in the process of changing the screen gesture, so that the second display brightness is determined according to the first brightness data, which is equivalent to the determination of the second display brightness according to the brightness of the main screen off display in the process of changing the screen gesture. By the mode, under the condition that the screen is turned over after the screen is turned off, the brightness of the secondary screen off display can be adjusted in a self-adaptive mode, the condition that the secondary screen off display brightness is low is effectively reduced, and the user experience is improved.

In one implementation manner of the first aspect, the method further includes:

and under the condition that the first moment is not in the first time interval, if the duration of the secondary screen display according to the second display brightness is up to a third preset duration, controlling the secondary screen to display according to a fifth display brightness, wherein the fifth display brightness is lower than the second display brightness.

For example, in the case where the display brightness of the display screen includes several options set in advance, such as a high-grade and a low-grade, the second display brightness may be a high-grade, and the fifth display brightness may be a low-grade. In the case where the display luminance of the display screen includes any value of the preset range, the fifth display luminance may be any value lower than the second display luminance within the preset range.

In the embodiment of the application, the display brightness of the screen-off display is reduced after the screen is turned off for a period of time. In this way, the power consumption of the screen can be effectively reduced.

In one implementation manner of the first aspect, the method further includes:

And under the condition that the auxiliary screen is displayed according to the fifth display brightness, if the current time is monitored to be in the first time interval, controlling the auxiliary screen to be displayed according to the sixth display brightness, wherein the sixth display brightness is higher than the fifth display brightness.

For example, in the case where the display brightness of the display screen includes several options set in advance, such as a high-level and a low-level, the second display brightness may be a high-level, the fifth display brightness may be a low-level, and the sixth display brightness may be a high-level, i.e., the sixth display brightness is the same as the second display brightness. In the case where the display luminance of the display screen includes any value of the preset range, the sixth display luminance may be any value higher than the fifth display luminance within the preset range, and the sixth display luminance may be the same as or different from the second display luminance.

In the embodiment of the application, the display brightness of the off-screen display is correspondingly adjusted according to the time change. And when the user is in the period of the peak period of using the electronic equipment, the display brightness of the off-screen display is improved. Through the mode, user experience is improved.

In one implementation manner of the first aspect, the method further includes:

If the secondary screen is displayed according to the fifth display brightness, if the screen posture of the electronic equipment is monitored to change, second brightness data are obtained, wherein the second brightness data comprise the display brightness of the primary screen display corresponding to each of M moments before a fourth moment, and the fourth moment is the moment when the screen posture of the electronic equipment stops changing;

determining a seventh display luminance according to the second luminance data;

And controlling the auxiliary screen to display according to the seventh display brightness.

For example, in the case where the display brightness of the display screen includes several options set in advance, such as a high-level and a low-level, the second display brightness may be a high-level, the fifth display brightness may be a low-level, and the seventh display brightness may be a high-level or a low-level. In the case where the display luminance of the display screen includes any value in the preset range, the seventh display luminance may be a value in the preset range.

It should be noted that, the execution sequence of the implementation manner is not specifically limited in the embodiment of the present application. For example, the steps of judging whether the screen gesture and the first time belong to the first time interval may be performed in parallel or in series. For another example, the judging step of judging whether the screen-off display duration reaches the third preset duration and the judging step of judging whether the current time belongs to the first time interval may be performed in parallel or may be performed in series.

In some implementations, the priority of judgment is that the screen gesture > timestamp > primary screen brightness before screen locking > primary screen brightness before turning over, namely, whether the screen gesture is the secondary screen upwards is judged first, whether the timestamp accords with a first time interval is judged, whether the primary screen brightness before screen locking is effective is judged, and when the primary screen is upwards, late night and the primary screen brightness before screen locking is ineffective, the primary screen brightness before turning over is calculated according to the primary screen brightness before turning over.

In other implementations, the priority of judgment is that the timestamp is the luminance of the main screen before screen locking and the screen gesture is the luminance of the main screen before turning over, namely, whether the timestamp accords with a first time interval is judged, whether the luminance before screen locking is effective is judged, whether the screen gesture is the upward side screen is judged, and when the main screen is upward, late night and the luminance before screen locking is invalid, the luminance is calculated according to the luminance of the main screen before turning over.

For the first implementation, if the priority of the screen gesture is higher than the timestamp, then the screen gesture needs to be monitored for any scene, and may also need to be monitored multiple times. For the second implementation, the priority of the timestamp and the brightness of the main screen before screen locking is higher than that of the screen gesture, so that the screen gesture only needs to be monitored in one scene. Compared with the prior art, the interaction flow of the second implementation mode is simpler, the interaction steps among the screen-off display application in the application layer, the equipment state management service module in the application framework layer and the attitude sensor service module in the hardware abstraction layer are reduced, and the power consumption is saved.

In the embodiment of the application, the monitoring screen gesture is kept in the process of screen-off display, and when the screen gesture changes, the display brightness of the secondary screen-off display is determined again. Due to the fact that the change of the screen posture possibly causes the perception accuracy of the photosensitive element to the ambient light, the situation that the display brightness of the auxiliary screen is not adaptively adjusted due to the fact that the perception of the ambient light is inaccurate can be effectively reduced, and the user experience is improved.

In a second aspect, there is provided an electronic device comprising a processor for executing a computer program stored in a memory, implementing the method of any one of the first aspects of the application.

In a third aspect, there is provided a system on a chip comprising a processor coupled to a memory, the processor executing a computer program stored in the memory to implement the method of any of the first aspects of the application.

In a fourth aspect, there is provided a computer readable storage medium storing a computer program which when executed by one or more processors performs the method of any of the first aspects of the application.

In a fifth aspect, the application provides a computer program product for causing a device to perform the method of any of the first aspects of the application when the computer program product is run on the device.

It will be appreciated that the advantages of the second to fifth aspects may be found in the relevant description of the first aspect, and are not described here again.

As shown in fig. 2b, when the folding screen mobile phone is folded outward in the arrow direction of fig. 2a, the angle α between the first screen area 201 and the second screen area 202 is greater than 180 ° and less than 270 °, and the folding screen mobile phone is in a semi-folded state (or stand state, calendar state, etc.). As shown in fig. 2 (c), when the angle between the first screen area 201 and the second screen area 202 is 270 °, the folding screen mobile phone is in a folded state (or called a fully folded state, etc.). It should be noted that, in the above examples, the description of the magnitude of the included angle between the first screen area 201 and the second screen area 202 of the folding-screen mobile phone in the unfolded state, the semi-folded state and the folded state is only an example, and the embodiment of the present application is not limited thereto. In addition, the folding screen is a folding screen mobile phone in an unfolded state, a semi-folded state or a folded state, and can also be called that the folding screen mobile phone is in an unfolded state, a semi-folded state or a folded state.

It should be understood that fig. 1 is only a structural example of an electronic device 100, and shows some modules related to a split screen display method according to an embodiment of the present application, and the structure illustrated in the embodiment of the present application does not constitute a specific limitation on the electronic device 100. In other embodiments of the application, electronic device 100 may include more or fewer components than shown, or certain components may be combined, or certain components may be split, or different arrangements of components.

The embodiment of the application takes an Android system with a layered architecture as an example, and illustrates a software structure of the electronic device 100.

Referring to fig. 3, a software block diagram of an electronic device 100 according to an embodiment of the present application is provided.

The layered architecture of the electronic device 100 divides the software into several layers, each with distinct roles and divisions. The layers communicate with each other through a software interface. In some embodiments, the Android system is divided into five layers, from top to bottom, an application layer, an application framework layer, an Zhuoyun rows (Android runtime) and system libraries, a hardware abstraction layer (hardware abstraction layer, HAL), and a kernel layer, respectively.

The application layer may include a series of application packages. As shown in fig. 3, the applications may include weather, clock, music, video applications, and off screen display (always on display, AOD) applications, among others. The off-screen application is used for realizing the self-adaptive adjustment of the off-screen display brightness through the off-screen display method provided by the embodiment of the application when the electronic equipment is in the off-screen state.

It will be appreciated that, in order to implement the off-screen display method of the present application, the electronic device includes corresponding hardware and/or software modules that perform the respective functions. The steps of an algorithm for each example described in connection with the embodiments disclosed herein may be embodied in hardware or in a combination of hardware and computer software. Whether a function is implemented as hardware or computer software driven hardware depends upon the particular application and design constraints imposed on the solution. Those skilled in the art may implement the described functionality using different methods for each particular application in conjunction with the embodiments, but such implementation should not be considered to be beyond the scope of the present application.

In the process of using the folding screen mobile phone, the display screen can be displayed through the bright screen, and a display function is provided for the user. When the user does not need to use the folding screen mobile phone, the display screen can automatically enter a screen-off (or screen-off) state under the operation of the user or after a preset time length so as to save the power consumption of the mobile phone.

In the embodiment of the present application, the screen-off state may also refer to that the corresponding screen does not display any screen, or only a small number of identifiers (such as time, date, etc.) are displayed on the screen to realize the screen-off display function. It can be understood that, compared with the bright screen state, the screen in the off-screen state basically does not need to be displayed, so that the power consumption caused by screen display can be saved.

Taking an external folding screen mobile phone as an example, in a folding state, since the main screen and the auxiliary screen are arranged oppositely, a display function is generally provided for a user through the main screen. For the secondary screen, a screen off state may be entered in some cases. Referring to fig. 4, a schematic diagram of an application scene of screen quenching is provided in an embodiment of the present application.

In the first scene, under the condition that the auxiliary screen is on, if no operation input by a user is received within a preset time period, the auxiliary screen can enter a screen-off state. For example, the sub-screen may display a desktop interface as shown in (a) of fig. 4 when displayed on a bright screen. If the operation input by the user is not received all the time, the auxiliary screen can enter the screen-off state after the preset time length is reached. For example, after entering the off-screen state, the secondary screen may not be displayed at all, entering the rest state (e.g., the power-on state) until the user enters other operation to illuminate the screen. As another example, as shown in (c) of fig. 4, the sub-screen may not be displayed in most areas of the display screen, and only a small amount of information such as time, date, and day of the week is displayed in the display area 41. In some implementations, the display content within the display area 41 may be selected and set among "off screen display" function options in a folding screen phone.

In the second scenario, when the secondary screen is on, after the user inputs the screen-off operation, the folding screen mobile phone enters the screen-off state (both the primary screen and the secondary screen enter the screen-off state) in response to the screen-off operation. For example, as shown in (b) of fig. 4, the off screen operation may be an operation in which the user presses the off key 42. And responding to the screen-off operation, and enabling the folding screen mobile phone to enter a screen-off state, wherein a screen-off display interface of the auxiliary screen can be shown as (c) in fig. 4.

The brightness of the screen display after screen extinction can be adaptively adjusted according to the ambient light brightness. For example, when the ambient light level is high, the off-screen display brightness is also high; when the ambient light level is low, the off-screen display brightness is also low. Typically the photosensitive element is disposed on the display of the cell phone. While for some out-folded screen handsets, the photosensitive element on the display screen is typically disposed on the main screen. When the external folding screen mobile phone is in a folded state and the secondary screen (the second screen area 202 shown in fig. 2) of the display screen is placed upwards, the secondary screen of the display screen cannot sense the ambient light brightness information, so that the external folding screen mobile phone cannot adaptively adjust the display brightness of the off screen. In other words, in the related art, the screen-off scheme is not intelligent enough, which may cause waste of power consumption.

In some application scenarios, referring to fig. 5, a schematic view of a scene with darkened ambient brightness after screen extinction is provided in an embodiment of the present application. As shown in fig. 5 (a), in the case of turning on and lighting, the ambient light is high, and at this time, the main screen 51 of the external folding screen mobile phone is placed upward, the sub-screen 52 is placed downward, and the photosensitive element 53 on the screen is disposed on the main screen 51, and in this case, the ambient light perceived by the photosensitive element 53 is the brightness of the main screen lighting display. As shown in fig. 5 (b), in the case of turning on the light, the main screen 51 of the external folding screen mobile phone is placed downward, and the sub-screen 52 is placed upward, in which case the ambient light brightness currently detected by the photosensitive element 53 on the screen is almost 0, and if the off-screen display brightness of the sub-screen 52 is adjusted by using the ambient light brightness, the adjusted off-screen display brightness of the sub-screen 52 may be low, affecting the user experience.

If the off-screen display brightness of the sub-screen 52 is adjusted by using the perceived ambient light level (the brightness of the main-screen bright-screen display) before the off-screen, the following problems may occur: if the light is turned off after a period of time of turning off the screen, as shown in fig. 5 (c), the brightness of the ambient light changes at this time, but since the brightness of the bright screen of the main screen before turning off is used to adjust the off-screen display brightness of the auxiliary screen 52, the adjusted auxiliary screen 52 may always maintain a higher brightness, and the off-screen display brightness cannot be adaptively adjusted, resulting in higher power consumption of the mobile phone.

In other application scenarios, referring to fig. 6, a schematic diagram of a mobile phone turning after screen extinction is provided in an embodiment of the present application. As shown in fig. 6, after the external folding screen mobile phone is turned off, the mobile phone turns from the posture 1 to the posture 7 along the arrow direction. When the mobile phone is in the posture 1, the main screen 51 is placed upwards, the auxiliary screen 52 is placed downwards, and the photosensitive element 53 is placed upwards. When the mobile phone is in the posture 7, the main screen 51 is placed downwards, the auxiliary screen 52 is placed upwards, and the photosensitive element 53 is placed downwards. During the turning process of the mobile phone, the photosensitive element 53 is always working, and the brightness of the environment sensed by the photosensitive element 53 changes from high to low along with the turning of the mobile phone. When the mobile phone is in the posture 7, the brightness of the environment sensed by the photosensitive element 53 is almost 0, that is, the brightness of the environment cannot be sensed correctly. The off-screen display brightness of the secondary screen 52 may be adjusted to be low according to the ambient light level sensed by the photosensitive element 53 at this time, affecting the user experience. Of course, if the ambient light level sensed by the photosensitive element 53 is almost 0, the off-screen display brightness of the sub-screen 52 may be adjusted by using the ambient light level sensed by the photosensitive element 53 in the previous posture (e.g., posture 6). However, due to the effect of turning over the mobile phone, the ambient light brightness sensed by the photosensitive element 53 at the gesture 6 is still not the correct ambient light brightness, and the adjusted off-screen display brightness of the secondary screen 52 may still be low, which affects the user experience.

In other application scenarios, only time information is considered, i.e. the off-screen display brightness is set according to time. For example, during daytime, such as 07:00-20:00, the off-screen brightness is set to a higher brightness; at night, such as 20:00-07:00, the off-screen brightness is set to a lower brightness. The self-adaption degree of the method is low, and the display brightness of the auxiliary screen can not be adjusted in a self-adaption mode under the condition that the user sleeps late or sleeps early, so that the user experience is affected.

As shown in the application scene, the off-screen display brightness of the secondary screen of the external folding screen mobile phone cannot be reasonably and adaptively adjusted to be proper brightness, so that the user experience is affected, and the power consumption of the mobile phone is also affected.

Based on the above, the embodiment of the application provides a screen-off display method. By the method, the correct environment light information of the current environment of the mobile phone can be accurately obtained based on the information of the time stamp, the brightness of the main screen before the screen is turned off and the brightness of the main screen before the mobile phone is turned over, so that the display brightness of the auxiliary screen is adjusted in a self-adaptive mode according to the correct environment light information, the use of a user is not affected, and meanwhile, unnecessary power consumption expenditure of screen display is saved.

The method for displaying the screen in a quenching mode is described in the following.

Referring to fig. 7, a flow chart of a screen-off display method according to an embodiment of the present application is shown. By way of example and not limitation, as shown in fig. 7, the off-screen display method may include the steps of:

S101, when the display state of the folding screen is monitored to be switched from bright screen display to off screen display, acquiring first display brightness and first moment.

The first display brightness is the display brightness of the bright screen display of the main screen before the screen is turned off, and the first moment is the screen turning off moment.

In some implementations, the off-screen display application of the application layer registers for listening with a power management service module of the application framework layer; when the display state of the folding screen is switched from bright screen display to off screen display, the power management service module responds to the change of the display state of the screen, and notifies the display state of the current screen of the off screen display application by using a callback function, and pulls up the off screen display application.

And after the off-screen display application is pulled up, the off-screen display application acquires the first display brightness and the first moment. In some implementations, the off-screen display application obtains a first display brightness and a first time from a device state management service module of an application framework layer.

It will be appreciated that there may be a variety of ways in which the state may be returned for some module/service interactions. In one implementation, a module that wants to acquire other modules/services may send a corresponding status return manner when registering with other modules/services, so that the peer module/service may perform status return according to the specified return manner. For example, when the off-screen display application registers monitoring with the power management service, executing state return when the state is indicated to change; accordingly, the power management service module returns the display state of the current screen to the off-screen display application in response to the change of the display state of the screen.

In another implementation, status information of other modules/services may be obtained by sending request information (or query messages). For example, after the off-screen display application is pulled up, request information is sent to the device state management service module; correspondingly, after receiving the request information, the equipment state management service module returns the first display brightness and the first moment to the off-screen display application.

It should be noted that in some embodiments, each module disposed in the framework layer may correspond to one or more processes/threads during system operation. For example, after the off-screen display application is pulled up, a process corresponding to the off-screen display application is initiated; in the course of an off-screen display application, multiple threads may be initiated for implementing different functions. For example, the function of the device state management service module in the embodiment of the application is realized by initiating a device state management thread; the function of the folding screen management service module in the embodiment of the application is realized by initiating a folding screen management thread; the power supply service thread is initiated to realize the functions of the power supply service module in the embodiment of the application. These threads may be processed in parallel or may be pulled up as needed.

S102, determining second display brightness according to the first display brightness and the first time.

And the second display brightness represents the display brightness of the secondary screen off display.

Step S102 is performed by the off-screen display application. Details are described in the examples below.

S103, controlling the auxiliary screen to display according to the second display brightness.

In some embodiments, step S102 may include:

S201, if the first moment is in the first time interval, determining the second display brightness as a first preset value.

S202, if the first time is not in the first time interval, determining second display brightness according to the first display brightness and the first time.

In some implementations, the display brightness of the display screen may include several options that are preset. For example, the display luminance includes a low-grade and a high-grade, wherein the display luminance of the high-grade is higher than that of the low-grade, and the values of the display luminances of the low-grade and the high-grade, respectively, are fixed. In this implementation, the display brightness of the display screen is switched between a high level and a low level, for example, the first preset value is a high level or a low level; and determining the second display brightness from the high grade and the low grade according to the first display brightness and the first moment. For example, assume a first time interval of 07:00-22:00 and a second time interval of 22:00-07:00. When the first time belongs to 07:00-22:00, determining the second display brightness as a high grade; and when the first time belongs to 22:00-07:00, determining the second display brightness from the high-grade and low-grade according to the first display brightness and the first time.

In other implementations, the display brightness of the display screen may include any value within a predetermined range. In this implementation manner, the display brightness of the display screen is switched within a preset range, for example, the first preset value is a certain value within the preset range; and determining the second display brightness from the preset range according to the first display brightness and the first moment. For example, assume a first time interval of 07:00-22:00 and a second time interval of 22:00-07:00. When the first time belongs to 07:00-22:00, determining the second display brightness as a first preset value, wherein the first preset value is a certain value in a preset range; and when the first time belongs to 22:00-07:00, determining the second display brightness from the preset range according to the first display brightness and the first time.

In some embodiments, the step of determining the second display brightness according to the first display brightness and the first time in S202 may include:

S301, detecting whether the first display brightness is effective or not according to the first time.

S302, if the first display brightness is effective, determining the second display brightness according to the first display brightness.

And S303, if the first display brightness is invalid, determining the second display brightness according to the screen gesture of the electronic equipment.

In some implementations, the step of detecting whether the first display brightness is valid according to the first time in S301 may include: if the time interval between the first time and the current time is smaller than a first preset duration, judging that the first display brightness is effective; and if the time interval between the first time and the current time is greater than a first preset duration, judging that the first display brightness is invalid.

The first preset duration may be preset according to experience, or obtained through learning according to a use habit of the user.

In some implementations, determining the second display brightness according to the first display brightness in S302 may be setting the second display brightness to the first display brightness, that is, setting the display brightness of the sub-screen off-screen display to the display brightness of the main-screen bright-screen display before off-screen.

In the embodiment of the application, before determining the second display brightness, whether the first display brightness is effective is detected according to the first time. By the method, under the condition that the brightness of the environment light changes greatly after the screen is turned off for a period of time, the screen-off display brightness can be adjusted in a self-adaptive mode, the condition that the high screen-off display brightness is always maintained in an application scene as shown in fig. 5 is effectively reduced, and the power consumption of the mobile phone is saved while the use requirement of a user is met.

In some embodiments, the step of determining the second display brightness according to the screen gesture of the electronic device in S303 may include:

S401, setting the second display brightness to a second preset value under the condition that the current screen posture of the electronic equipment is that the auxiliary screen faces upwards.

S402, monitoring the screen gesture of the electronic equipment under the condition that the current screen gesture of the electronic equipment is that a main screen faces upwards; when the screen gesture of the electronic equipment is switched from a main screen to a secondary screen, acquiring first brightness data; and determining the second display brightness according to the first brightness data.

The first brightness data comprise display brightness of main screen off display corresponding to N times before a second time, and the second time is when the screen gesture of the electronic equipment is switched to the time when the auxiliary screen is upward. It should be noted that, in some implementations, the first luminance data may also include the second time and the display luminance of the main screen off display corresponding to each of N times before the second time. It will be appreciated that such implementations are also within the scope of embodiments of the present application.

It should be noted that, the luminance data may be stored in a stack, the stack length is limited, and after the latest luminance data is pushed in, the luminance data with the longest storage time is played. Of course, the luminance data may also be stored in other forms, such as a matrix, a number of columns, etc., which are not particularly limited in the embodiment of the present application.

According to the embodiment of the application, the brightness of the secondary screen off display is determined according to the screen gesture of the electronic equipment, in this way, under the condition that the screen is turned over after off, the brightness of the secondary screen off display can be adjusted in a self-adaptive manner, the occurrence of the condition that the secondary screen off display brightness is lower in an application scene as shown in fig. 6 is effectively reduced, and the user experience is improved.

In some implementations, the step of determining the second display luminance according to the first luminance data in S402 may include:

when fourth display brightness different from the third display brightness is detected for the first time, determining the second display brightness according to the second moment and a third moment corresponding to the fourth display brightness;

Optionally, if the time interval between the second time and the third time is smaller than a second preset duration, determining the second display brightness according to the fourth display brightness; and if the time interval between the second time and the third time is greater than or equal to a second preset duration, determining the second display brightness according to the third display brightness.

Exemplary, referring to fig. 8, a schematic diagram of a luminance data time axis according to an embodiment of the present application is shown. As shown in fig. 8, in the time axis direction, the first brightness data comprises 6 parts in sequence 6, 36, 63, 3. Wherein 6 and 3 respectively correspond to a luminance value of the main screen extinguishing display. And T1 is a second moment, namely, a moment when the screen gesture of the electronic equipment is switched to the side-up state. At this time, the third display luminance is a display luminance corresponding to the time T2. According to the time reversal sequence, respectively corresponding display brightness at two moments of T2 and T3 are compared, and are 3 and the same; continuously comparing the display brightness corresponding to each of the T2 and the T4 moments, wherein the display brightness is 3 and the same; and continuously comparing the display brightness corresponding to the two moments T2 and T5 respectively, wherein the display brightness is 3 and the same. And continuously comparing the display brightness corresponding to the T2 and the T6 respectively, wherein one is 3, the other is 6, the display brightness corresponding to the T6 is a value which is detected for the first time and is different from the display brightness corresponding to the T2, and the display brightness at the T6 is marked as fourth display brightness. Calculating a time interval between T1 and T6, and if the time interval is smaller than a second preset duration, determining the display brightness corresponding to the 6 as second display brightness; if the time interval is greater than or equal to the second preset duration, determining the display brightness corresponding to 3 as the second display brightness. If the current first brightness data is 3, that is, the fourth display brightness different from the third display brightness cannot be detected, and the display brightness corresponding to 3 is determined as the second display brightness.

In some cases, the display brightness of the main screen is not necessarily updated at the time when the screen posture is switched to the sub-screen upward, and thus, as shown in fig. 8, the display brightness corresponding to the update time (T2) immediately before T1 is compared with the display brightness as a reference.

In the embodiment of the application, the first brightness data can reflect the change condition of the brightness of the main screen off display in the process of changing the screen gesture, so that the second display brightness is determined according to the first brightness data, which is equivalent to the determination of the second display brightness according to the brightness of the main screen off display in the process of changing the screen gesture. By the method, under the condition that the screen is turned over after the screen is turned off, the brightness of the secondary screen off display can be adjusted in a self-adaptive mode, the condition that the secondary screen off display brightness is low in an application scene as shown in fig. 6 is effectively reduced, and the user experience is improved.

The implementation of steps S901-S903 can be seen from the description in the embodiment of S101.

S904, the attitude sensor service module provides attitude data to the device state management service module.

S905, the equipment state management service module detects whether the current screen gesture is upward with the gesture data, and sends the detection result to the off-screen display application.

In other implementations, referring to fig. 12, an interactive flow diagram of a method for displaying a screen on a screen is provided in an embodiment of the present application. As shown in fig. 12, the interactive flow of the off-screen display method may include the following steps:

S1210, if the current screen gesture is a sub-screen facing up, then S1109 and S1111-S1114 are performed.

The embodiment of fig. 12 differs from the embodiments of fig. 9-11 in that: in the embodiment of fig. 9 to 11, the priority is determined as the screen gesture > timestamp > primary screen brightness before screen locking > primary screen brightness before turning over, that is, whether the screen gesture is the secondary screen facing upwards is determined first, whether the timestamp accords with the first time interval is determined, whether the primary screen brightness before screen locking is effective is determined, and when the primary screen faces upwards, is late at night, and the primary screen brightness before screen locking is ineffective, the primary screen brightness before turning over is calculated. In the embodiment of fig. 12, the priority is determined as the timestamp > the brightness of the main screen before screen locking > the screen gesture > the brightness of the main screen before turning over, that is, whether the timestamp accords with the first time interval is determined, whether the brightness before screen locking is valid is determined, whether the screen gesture is the upward side of the screen, and when the main screen is upward, late night and the brightness before screen locking is invalid, the calculation is performed according to the brightness of the main screen before turning over.

As can be seen from the specific steps in the embodiments of fig. 9 to 12, if the priority of the screen gesture is higher than the timestamp, the screen gesture needs to be monitored in any scene; especially in the scenario shown in the embodiment of fig. 10, it is also necessary to monitor the screen gesture multiple times. In the embodiment of fig. 12, the priority of the timestamp and the brightness of the main screen before screen locking is higher than that of the screen gesture, so that the screen gesture only needs to be monitored in one scene. Compared with the prior art, the interactive flow of the embodiment of fig. 12 is simpler, so that the interactive steps among the screen-off display application in the application layer, the equipment state management service module in the application framework layer and the attitude sensor service module in the hardware abstraction layer are reduced, and the power consumption is saved.

It should be noted that, in addition to the interactive flows shown in fig. 9-12, other interactive flows may be adopted, for example, the order of some steps is changed, but the technical solution formed by the change of the interactive flow order is still within the protection scope of the embodiments of the present application.

As can be seen from the embodiments of fig. 9 to fig. 12, the method for displaying an off screen provided in the embodiment of the present application is equivalent to comprehensively considering several factors including a time stamp, brightness of a main screen before screen locking, and brightness of the main screen before screen turning.
