Description

AOD display method and electronic equipment

Technical Field

The application relates to the technical field of electronics, in particular to an AOD display method and electronic equipment.

Background

Currently, electronic devices are provided with various interaction modes, and a rich experience is provided for users in the process of using the electronic devices. In general, an electronic device may include a bright screen state in which a user may perform various operations on the electronic device and a dead screen (or lock screen) state; in the off-screen state, the electronic equipment enters into dormancy, if a user wants to view some information, such as time, date or notification, in the off-screen state, the user needs to press a power key to trigger the electronic equipment to display a screen saver interface to acquire the information, and the operation is inconvenient for the user.

With the development of off-screen display (AOD) technology, the electronic device can continuously display useful information, such as continuous display time, date, notification and the like, in an off-screen state. However, in the current related art, the content of information displayed by the AOD is limited, and the display effect is poor.

Disclosure of Invention

The application provides an AOD display method and electronic equipment, which can improve the AOD display effect.

In a first aspect, the present application provides an AOD display method, the method being performed by an electronic device, comprising:

acquiring sensor data, wherein the sensor data comprises screen noise data generated by the luminescence of a display screen of the electronic equipment;

if the current state of the display screen of the electronic equipment is a preset state, calculating current screen noise, wherein the preset state represents that the display screen of the electronic equipment is in a screen-off state and is displayed in a full-screen AOD;

and performing noise removal on the sensor data according to the current screen noise, and performing screen dimming on the sensor data after the noise removal so as to adjust the full-screen AOD display effect.

The sensor data may be ambient light data, which may be collected by an ambient light sensor. Optionally, the electronic device may acquire the data collected by the ambient light sensor with a fixed period of time and integrate the data to obtain the ambient light data. Alternatively, the fixed duration may be 350 milliseconds. After the sensor is acquired, the electronic device can monitor the state of the display screen, if the current state of the display screen is a preset state, the electronic device is indicated to be in full-screen AOD display, and then screen dimming is required according to the ambient light data so as to adapt to the ambient light with different intensities. And because the acquired sensor data includes the screen noise data generated by the light emission of the display screen, the electronic device needs to remove the screen noise caused by the screen noise data. Thus, the electronic device may calculate the current screen noise, noise-remove the sensor data according to the current screen noise, and screen-dim according to the noise-removed sensor data.

It will be appreciated that after screen dimming according to the currently acquired sensor data, the electronic device may continue to acquire sensor data in the next cycle and repeatedly perform the above steps to achieve automatic continuous dimming of the display screen.

According to the implementation mode, when the electronic equipment performs AOD display on the full-screen interface, screen noise can be removed from the acquired ambient light data, real ambient light data is obtained, and further continuous and automatic screen dimming is performed according to the real ambient light data, so that the AOD display effect is better, and user experience is improved.

With reference to the first aspect, in some implementations of the first aspect, the calculating the current screen noise includes:

monitoring backlight parameters of the display screen and a picture brushing event, wherein the backlight parameters represent brightness information of the display screen, and the picture brushing event represents RGB information of an image displayed by the display screen;

and calculating the current screen noise according to the backlight parameter and the picture brushing event.

The electronic device may calculate current screen noise according to the backlight parameters and the image brushing event of the display screen, and optionally, the electronic device may start a matte write-back (CWB) function to monitor the backlight parameters and the image brushing event of the display screen. Here, the backlight parameter of the display screen may represent brightness information of the display screen, the brightness value range is generally 0 to 4096 levels, the brush event may represent red, yellow, blue, RGB information of an image displayed by the display screen, and the RGB value range is generally 0 to 255. Then, the electronic equipment can call a matting algorithm library to calculate according to the backlight parameters and the matting event so as to obtain the current screen noise.

With reference to the first aspect, in some implementations of the first aspect, the foregoing sensor data is ambient light data, and calculating the current screen noise according to the backlight parameter and the map brushing event includes:

determining first noise according to the backlight parameters and a first curve function, wherein the first curve function represents the corresponding relation between different brightness values of a display screen and the influence of the different brightness values on the ambient light, and the first noise represents the influence of the ambient light corresponding to the backlight parameters;

determining second noise according to the image brushing event and a second curve function, wherein the second curve function represents the corresponding relation between different RGB information of a display image and the influence on the ambient light, and the second noise represents the influence on the ambient light corresponding to the image brushing event;

and calculating the current screen noise according to the first noise and the second noise.

The matting algorithm library may include at least two curve functions, wherein a first curve function represents a corresponding relation between different brightness values of the display screen and an influence on ambient light, and a second curve function represents a corresponding relation between different RGB information of the display image and the influence on ambient light. Therefore, when the electronic device monitors the current backlight parameter and the image brushing event, the magnitude of the influence on the ambient light corresponding to the backlight parameter (representing the brightness information of the display screen), namely the first noise, can be determined according to the first curve function, and the magnitude of the influence on the ambient light corresponding to the image brushing event (representing the RGB information of the image displayed by the display screen), namely the second noise, can be determined according to the second curve function. The electronic device may then calculate a current screen noise from the first noise and the second noise.

Since the electronic device may determine the brightness value and the RGB value when determining the first noise corresponding to the backlight parameter and the second noise corresponding to the image brushing event, but the brightness value and the RGB value in the actual scene are not necessarily at the full level, the electronic device needs to weight the first noise and the second noise when calculating the current screen noise according to the first noise and the second noise, so as to obtain the noise corresponding to the actual scene.

In some implementations, calculating the current screen noise according to the first noise and the second noise includes: and carrying out weighted summation on the first noise and the second noise to obtain the current screen noise.

It can be understood that when determining the weighting coefficients corresponding to the first noise and the second noise respectively, the electronic device may be determined according to the brightness value corresponding to the backlight parameter and the RGB value corresponding to the image brushing event, or may be determined in combination with the actual scene requirement.

According to the implementation mode, the electronic equipment calculates the current screen noise by monitoring the backlight parameters of the display screen and the image brushing event, and then removes noise in the sensor data according to the current screen noise, so that the AOD display effect is better.

With reference to the first aspect, in some implementations of the first aspect, after the acquiring the sensor data, the method further includes:

monitoring a screen-on event and a screen-off event of the display screen, and storing the state of the display screen according to the screen-on event and the screen-off event of the display screen.

The electronic device needs to determine what state the display screen is currently in, because the electronic device determines whether the current state of the display screen is a preset state. Here, the electronic device may monitor the on-screen event and the off-screen event of the display screen, alternatively, the electronic device may monitor the on-screen event and the off-screen event of the display screen through the HWC module in the AP processor. If a bright screen event and a dead screen event are monitored, the state of the display screen may be saved.

With reference to the first aspect, in some implementations of the first aspect, the performing screen dimming according to the sensor data after noise removal includes:

judging whether a preset condition is met according to the sensor data after noise removal, wherein the preset condition represents that the change degree of the sensor data reaches a threshold value;

and if the preset condition is met, performing screen dimming according to the sensor data after the noise is removed.

The electronic device enters the sleep state when in the screen-off state, and if the AOD display effect is to be adjusted, the processor needs to be awakened. At this time, if the electronic device wakes up the processor every time the sensor data after noise removal is calculated, the processing power consumption of the electronic device will be increased. Therefore, after the sensor data after noise removal is obtained, the electronic device can also judge whether the preset condition is met, if the preset condition is met, screen dimming is performed, and if the preset condition is not met, screen dimming is not performed currently. The preset condition can represent that the change degree of the sensor data reaches a threshold value, the change degree of the sensor data can be determined according to the difference between the sensor data after the current noise is removed and the sensor data after the last noise is removed, and if the change degree of the sensor data reaches the threshold value, the preset condition is met, so that screen dimming can be performed. Thus, the processing power consumption of the electronic device can be reduced.

With reference to the first aspect, in some implementations of the first aspect, the noise removing the sensor data according to the current screen noise includes:

And removing noise from the sensor data based on the matting calibration data and the current screen noise.

In the process of removing noise of the electronic equipment, in order to further improve the accuracy of the obtained sensor data, the electronic equipment can be provided with the matting calibration data in advance, and the matting calibration data is used as a reference to remove noise of the sensor data based on current screen noise.

The full-screen AOD application, the matting algorithm library, the HWC module and the module for storing matting calibration data (simply referred to as a storage module) can be integrated in the AP processor, and the ambient light sensor application, the full-screen AOD virtual sensor application, the ambient light sensor drive and the full-screen AOD virtual sensor drive can be integrated in the Modem processor. The AOD display method may include:

The driving of the ambient light sensor judges whether the current state of the display screen is a preset state, if the current state is not the preset state, the data collected by the ambient light sensor is continuously obtained and integrated, and if the current state is the preset state, the ambient light data is sent to the HWC module through the application of the ambient light sensor;

the HWC module monitors a screen-on event and a screen-off event of the display screen, judges whether the current state of the display screen is a preset state, if not, continues to monitor the screen-on event and the screen-off event of the display screen, if so, starts a CWB function, monitors backlight parameters and a map-brushing event of the display screen;

The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application. Wherein, in the description of the embodiments of the present application, unless otherwise indicated, "/" means or, for example, a/B may represent a or B; "and/or" herein is merely an association relationship describing an association object, and means that three relationships may exist, for example, a and/or B may mean: a exists alone, A and B exist together, and B exists alone. In addition, in the description of the embodiments of the present application, "plurality" means two or more than two.

The terms "first," "second," "third," and the like, are used below for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first", "a second", or a third "may explicitly or implicitly include one or more such feature.

Currently, electronic devices are provided with various interaction modes, and a rich experience is provided for users in the process of using the electronic devices. In general, an electronic device may include a bright screen state in which the electronic device is awakened and a dead screen (or lock screen) state in which a user may perform various operations on the electronic device, such as making a call, viewing a video, browsing a web page, etc.; in the off-screen state, the electronic device enters into sleep, and the user can not operate any more, but if the user wants to view some information, such as time, date or notification, in the off-screen state, the user needs to press a power key, and at this time, the electronic device can be triggered to display a screen saver interface, and the screen saver interface can be presented with the information such as time, date or notification. In some related technologies, the screen saver interface of the electronic device may also receive an interactive operation of a user, for example, a photographing control is presented on the screen saver interface, and the user may trigger to start the photographing application without unlocking the screen. However, these processes in the related art all require the user to trigger the display screen saver interface to be implemented, and in some scenarios the user may not be convenient to operate the electronic device.

Accordingly, AOD technology has grown and AOD displays have enabled electronic devices to continue to display useful information, such as time, date, notification, etc., in an off-screen state, i.e., electronic devices that still display such information in the event of an off-screen (i.e., a blackout screen). For example, the effect of AOD display in the related art is shown in fig. 1, that is, information such as time, date, electric quantity and the like may be displayed in a partial area of the display screen, and in the case that a message notification arrives, notification prompt information may also be displayed.

However, as can be seen from the example shown in fig. 1, since the electronic device is AOD displayed in a partial area of the display screen, the content of the displayed information is relatively limited; in the related art, no control which can be operated by a user exists on an AOD display interface of the electronic equipment, namely interaction with the user cannot be performed, and if the user needs to interact with the electronic equipment in a screen-off state, the screen-protection interface is still triggered or the screen is unlocked and then the operation is performed. That is, the AOD display method in the related art is not highly interactive to the user.

The AOD display method provided by the embodiment of the application can be used for carrying out AOD display on the full screen interface of the electronic equipment, and can be used for carrying out continuous and automatic screen dimming according to the influence of ambient light, thereby improving the AOD display effect and correspondingly improving the user experience.

The application layer may include a series of application packages, which may include, for example, a full screen AOD application, an ambient light sensor application, and a full screen AOD virtual sensor application. In addition, the application package may include applications (not shown in fig. 3) such as cameras, gallery, calendar, phone calls, maps, navigation, WLAN, bluetooth, music, video, short messages, etc.

The hardware description layer may include a matting algorithm library and HWC (hwcomposer) module.

The ambient light sensor application may, among other things, obtain ambient light data from the ambient light sensor driver and transmit the ambient light data to the HWC module of the AP processor. The HWC module is a module for synthesizing and displaying windows (layers) in Android, can monitor a bright screen event and a off screen event of the electronic equipment, monitors backlight parameters and a picture brushing event when the off screen is off and the AOD is in a full screen display state, invokes a picture matting algorithm library to calculate screen noise at the moment, and finally carries out screen noise removal on received ambient light data in combination with picture matting calibration data and returns the screen noise to an ambient light sensor application. The ambient light sensor application sends ambient light data with screen noise removed to the full-screen AOD virtual sensor drive through the ambient light sensor drive, the full-screen AOD virtual sensor drive carries out threshold filtering on the received ambient light data, and when preset conditions are met, the ambient light data is transmitted to the full-screen AOD application through the full-screen AOD virtual sensor application for processing. The full screen AOD application may then dim the screen according to the received ambient light data.

It can be appreciated that the full-screen AOD virtual sensor driver described above is a virtual driver that can be virtually generated when the electronic device is powered on and that can begin to operate when the electronic device is powered on.

In some embodiments, the software system of the electronic device may include an application framework layer, an Zhuoyun row (Android run) and a system library in addition to the software structure shown in fig. 3.

The telephony manager is used to provide the communication functions of the electronic device 100. Such as the management of call status (including on, hung-up, etc.). The resource manager provides various resources for the application program, such as localization strings, icons, pictures, layout files, video files, and the like. The notification manager allows the application to display notification information in a status bar, can be used to communicate notification type messages, can automatically disappear after a short dwell, and does not require user interaction.

For example, a text message is prompted in a status bar, a prompt tone is emitted, the electronic device vibrates, and an indicator light blinks, etc.

Android runtimes include core libraries and virtual machines. Android run time is responsible for scheduling and management of the Android system.

The core library consists of two parts: one part is a function which needs to be called by java language, and the other part is a core library of android.

The system library may include a plurality of functional modules. For example: surface manager (surface manager), media library (media library), three-dimensional graphics processing library (e.g., openGL ES), 2D graphics engine (e.g., SGL), etc. The surface manager is used to manage the display subsystem and provides a fusion of 2D and 3D layers for multiple applications.

The 2D graphics engine is a drawing engine for 2D drawing.

For easy understanding, the following embodiments of the present application will take an electronic device having a structure shown in fig. 2 and fig. 3 as an example, and specifically describe an AOD display method provided by the embodiments of the present application with reference to the accompanying drawings and application scenarios.

Firstly, an application scenario of the AOD display method provided by the application is introduced, in general, when a user uses an electronic device, if a power key is pressed down, the electronic device can be triggered to enter a screen-off state, and in the case that the electronic device does not start an AOD function, the screen-off state of the electronic device is a black screen state, and at the moment, the user cannot perform interactive operation with the electronic device. And in the case that the electronic device turns on the AOD function, the electronic device may perform AOD display. The embodiment of the application provides a mode for starting an AOD function, as shown in fig. 4, a display and brightness control 41 is displayed on a setting interface of electronic equipment, a user clicks the display and brightness control 41, and the electronic equipment enters the setting interface of display and brightness; and displaying an off-screen display control 42 on the setting interface of display and brightness, clicking the off-screen display control 42 by a user, and entering the setting interface of off-screen display by the electronic equipment.

As can be seen from the setup interface of the off screen display, if the user wants to turn on the AOD function, the switch control 43 can be clicked and a different off screen style selected when the AOD function is turned on. In the embodiment of the application, the screen quenching grid is provided with a full-screen AOD mode and a classical mode, wherein the full-screen AOD mode is used for displaying information to be displayed on a full-screen interface of the electronic equipment. In some embodiments, in the full-screen AOD mode, the user may also customize the display mode, pattern, color, background, etc. of the selected information, and optionally, the background may be the same as or different from the screen saver interface set by the electronic device.

For example, as shown in fig. 5, the full-screen AOD display interface provided by the embodiments of the present application may be displayed after the electronic device enters the off-screen state after the user presses the power key. As can be seen from fig. 5, the full screen interface of the electronic device is displayed with information such as time, date, and electric quantity, and the background of the information fills the full screen interface of the electronic device. And controls of the camera application and the flashlight application are also displayed below the full screen interface, and the controls can respond to triggering operations of a user, for example, the user clicks the controls of the camera application, and the electronic device can enter the camera running interface. In the case where the electronic device receives the message notification, notification prompt information may be displayed on the interface shown in fig. 5, and the user may click on the prompt information to display, or the like. That is, in the off-screen state in the embodiment of the present application, the user may still perform an interactive operation with the electronic device due to the full-screen AOD display.

In some embodiments, the display brightness of the electronic device when performing full-screen AOD display may be lower than the display brightness of the screen saver interface, which may reduce the processing power consumption of the electronic device to some extent. For example, in the case where the background of the AOD display is the same as the screen saver interface provided by the electronic device, the display brightness at the time of full-screen AOD display is darker than the display brightness of the screen saver interface from the visual point of view. In other embodiments, where the display brightness is lower than the display brightness of the screen saver interface when full-screen AOD display is performed, the electronic device may highlight text information on the full-screen AOD display interface to facilitate a user focusing on the displayed text information.

However, when the electronic device performs full-screen AOD display, the display brightness of the electronic device is easily affected by external ambient light, for example, the brighter the display brightness of the electronic device is required when the ambient light is stronger, the darker the display brightness of the electronic device is required when the ambient light is weaker, and the electronic device needs to perform screen dimming according to the ambient light. Because the current popular electronic devices are all comprehensive screens, and the ambient light sensor for collecting the ambient light data is usually arranged below the display screen, the ambient light data collected by the ambient light sensor is affected by the screen lighting, that is, the collected ambient light data contains screen noise. Therefore, when the embodiment of the application is used for full-screen AOD display, if the electronic equipment is required to realize accurate screen dimming, the screen luminous influence in the ambient light data is required to be removed, namely screen noise is removed.

Based on this, an embodiment of the present application proposes an AOD display method, and fig. 6 is a schematic flow chart of an example of an AOD display method provided by the embodiment of the present application, where the method may be executed by an electronic device, and may specifically include:

s101, acquiring sensor data.

The sensor data may be ambient light data, which may be collected by an ambient light sensor. In one implementation, the ambient light sensor driver may acquire data collected by the ambient light sensor and integrate the data with a fixed period of time. Alternatively, the fixed duration may be 350 milliseconds (ms), i.e., the ambient light sensor drive acquires and integrates ambient light data once every 350 ms. It will be appreciated that, because the ambient light sensor collects data and is affected by the screen luminescence, the ambient light sensor drives the integrated ambient light data to include real ambient light data and screen noise data.

Alternatively, the sensor data (i.e., ambient light data) acquired by the electronic device may include data for three channels of color, intensity, and direction.

S102, if the current state of the display screen of the electronic equipment is a preset state, calculating current screen noise.

The preset state may represent that the display screen of the electronic device is in a screen off state (Doze state) and is being displayed in a full screen AOD. If the current state of the display screen of the electronic device is a preset state, the electronic device is indicated to be in full-screen AOD display, and then screen dimming is required according to the ambient light data so as to adapt to the ambient light with different intensities. Because the acquired sensor data includes the screen noise data, the electronic device needs to remove the screen noise caused by the screen noise data, so that the electronic device needs to calculate the current screen noise at this time.

In one implementation, the electronic device may monitor a bright screen event and a dead screen event of the display screen, and save a state of the display screen according to the bright screen event and the dead screen event. For example, when the electronic device monitors a screen-off event, the state of the display screen is saved as a screen-off state (Doze). Alternatively, the electronic device may monitor the display for a bright screen event and a off screen event through a HWC module in the AP processor. For example, the user is using the electronic device to perform interactive operation, if the power key is pressed, the electronic device is triggered to enter a screen off state, and the electronic device can monitor the screen off event.

In one implementation, in calculating the current screen noise, the electronic device may calculate the current screen noise based on the backlight parameters of the display screen and the brush event. Optionally, when the current state of the display screen of the electronic device is a preset state, the electronic device may start a scratch write back (CWB) function to monitor backlight parameters and a brush event of the display screen. The backlight parameter of the display screen may represent brightness information of the display screen, the brightness value range is generally 0 to 4096 level, the image brushing event may represent RGB information of an image displayed by the display screen, and the RGB value range is generally 0 to 255. Then, the electronic equipment can call a matting algorithm library to calculate according to the backlight parameters and the matting event so as to obtain the current screen noise.

Optionally, the matting algorithm library may include at least two curve functions, a first curve function represents a corresponding relationship between different brightness values of the display screen and an influence magnitude caused to the ambient light, and a second curve function represents a corresponding relationship between different RGB information of the display image and the influence magnitude caused to the ambient light. Therefore, if the electronic device monitors the current backlight parameter and the image brushing event, the influence of the backlight parameter on the ambient light, namely the first noise, can be determined according to the first curve function, and the influence of the image brushing event on the ambient light, namely the second noise, can be determined according to the second curve function. The electronic device may then calculate a current screen noise from the first noise and the second noise. Optionally, the electronic device may weight sum the first noise and the second noise to calculate the current screen noise; it should be noted that, the electronic device may determine the weighting coefficient according to the brightness value corresponding to the backlight parameter and the RGB value corresponding to the image brushing event, but the embodiment of the present application does not limit the manner of weighting and summing.

S103, carrying out noise removal on the sensor data according to the current screen noise, and carrying out screen dimming according to the sensor data after the noise removal so as to adjust the full-screen AOD display effect.

Because the current screen noise is obtained through calculation, the acquired sensor data comprise real ambient light data and screen noise data, and then the electronic equipment can remove the screen noise data in the sensor data to obtain the real ambient light data. In one implementation manner, when noise is removed from the sensor data, the noise-removed channel values may be obtained by processing the three channels corresponding to the sensor data, and then the electronic device may integrate the noise-removed channel values to obtain the noise-removed sensor data. In one implementation, the electronic device may also combine the stored matting calibration data to remove screen noise data from the sensor data to obtain real ambient light data.

Then, the electronic device can perform screen dimming according to the sensor data after noise removal so as to adjust the full-screen AOD display effect. Because the AOD display is performed in the off-screen state of the electronic equipment, and the electronic equipment is in the dormant state in the off-screen state, if the electronic equipment needs to adjust the AOD display effect, the processor needs to be awakened to realize the AOD display. Therefore, in order to avoid the problem that the power consumption is too high caused by frequent wake-up of the processor by the electronic device, in an achievable manner, the electronic device can also judge whether a preset condition is met after obtaining the sensor data after noise removal, if the preset condition is met, screen dimming is performed, and if the preset condition is not met, screen dimming is not performed currently.

Optionally, the preset condition may indicate that the degree of change of the ambient light data reaches a threshold, where the degree of change of the ambient light data may be determined according to a difference between the ambient light data after the current noise is removed and the ambient light data after the previous noise is removed, and if the degree of change of the ambient light data reaches the threshold, it indicates that the preset condition is met, and the electronic device may perform the screen dimming processing.

It will be appreciated that after screen dimming according to the currently acquired sensor data, the electronic device may continue to acquire sensor data in the next cycle and repeatedly perform steps S102 to S103 to achieve automatic continuous dimming of the display screen.

According to the AOD display method, when the electronic equipment performs AOD display on the full-screen interface, screen noise can be removed from the acquired ambient light data, so that real ambient light data is obtained, and further continuous and automatic screen dimming is performed according to the real ambient light data, so that the AOD display effect is better, and user experience is improved.

For the AOD display method provided by the embodiment of the present application, the following description is made with reference to the software architecture shown in fig. 3, and fig. 7 is a module interaction timing diagram of an example of the AOD display method provided by the embodiment of the present application, where the embodiment is shown by integrating a full-screen AOD application, a matting algorithm library, a HWC module, and a module for storing matting calibration data (abbreviated as a storage module) into an AP processor, and integrating an ambient light sensor application, a full-screen AOD virtual sensor application, an ambient light sensor driver, and a full-screen AOD virtual sensor driver into a Modem processor, which may specifically include:

S11, driving by an ambient light sensor to acquire acquired data and integrating, and calculating to obtain ambient light data.

Optionally, the ambient light sensor driver may acquire data collected by the ambient light sensor with a fixed period of time as a period and integrate the data to obtain ambient light data, where the ambient light data includes real ambient light data and screen noise data.

S12, the ambient light sensor drive judges whether the current state of the display screen is a preset state, if so, S13 is executed, and if not, S11 is executed.

The preset state may characterize that a display screen of the electronic device is in a screen off state (Doze) and is being displayed in a full screen AOD. If the current state of the display screen is a preset state, the ambient light sensor is driven to execute subsequent operations; if the current state of the display screen is not the preset state, the ambient light sensor is driven to continuously acquire the acquired data and integrate.

Alternatively, the ambient light sensor driver may obtain the current state of the display screen from the HWC module in the AP processor.

S13, the ambient light sensor driver sends ambient light data to the HWC module through the ambient light sensor application.

Alternatively, the ambient light sensor driver may send ambient light data to the HWC module by running a stop run stop mechanism.

S14, the HWC module monitors a bright screen event and a dead screen event of the display screen.

S15, the HWC module judges whether the current state of the display screen is a preset state, if so, the S16 is executed, and if not, the S14 is executed.

That is, if the current state of the display screen is a preset state, the HWC module performs a subsequent operation; if the current state of the display screen is not the preset state, the HWC module continuously monitors the bright screen event and the off screen event of the display screen.

S16, the HWC module starts the CWB function, monitors backlight parameters of the display screen and monitors a map brushing event.

S17, the HWC module calls a matting algorithm library to calculate and obtain current screen noise according to the backlight parameters and the matting event.

The execution process of S17 may be referred to the description of S102, and will not be repeated here.

And S18, the HWC module performs noise removal on the ambient light data according to the current screen noise to obtain real ambient light data.

The execution process of S18 may be referred to the description of S103, and will not be repeated here. Optionally, the HWC module may call the matting calibration data stored in the storage module to remove the screen noise data in the ambient light data, to obtain the real ambient light data.

S19, the HWC module sends the real ambient light data to the ambient light sensor driver via the ambient light sensor application.

Likewise, the HWC module may send real ambient light data to the ambient light sensor driver via a run stop mechanism.

S20, the ambient light sensor driver sends real ambient light data to the full-screen AOD virtual sensor driver.

S21, judging whether the real environment light data meet the preset conditions or not by the full-screen AOD virtual sensor driver, executing S22 if the real environment light data meet the preset conditions, and not currently carrying out screen dimming if the real environment light data do not meet the preset conditions.

The preset condition may be that the degree of change of the ambient light data reaches a threshold value, and if the difference between the current real ambient light data and the last real ambient light data reaches the threshold value, a subsequent screen dimming step is performed.

S22, the full-screen AOD virtual sensor driver sends the real ambient light data to the full-screen AOD application through the full-screen AOD virtual sensor application.

S23, screen dimming is carried out by the full-screen AOD application according to the real environment light data so as to adjust the full-screen AOD display effect.

Optionally, the screen dimming performed by the full-screen AOD application may be to adjust parameters such as brightness and color of the display screen, so as to adapt to the current ambient light to the greatest extent.
