Description

Compensation method and electronic equipment

Technical Field

The present application relates to the field of terminal technologies, and in particular, to a compensation method and an electronic device.

Background

Along with the popularization of electronic products, electronic devices such as mobile phones and computers are deeper and deeper into lives of people, screens of the electronic devices are larger, and electronic devices with foldable screens are available afterwards for carrying conveniently.

In order to provide better display experience for users, organic Light Emitting Diodes (OLEDs) are widely used in display screens because of their characteristics of self-luminescence, high brightness, wide viewing angle, fast response, and RGB full-color device fabrication. The OLED emits light by using the characteristics of electroluminescence of organic materials, which have a life limit, and thus, as the use time of the display screen increases, there are problems of material exhaustion and aging. For example, when a certain fixed position of the display screen displays the same and still image picture for a long time, the organic material corresponding to the sub-pixels at these positions will be more severely worn than the organic material corresponding to the sub-pixels at other positions, and the organic materials corresponding to different sub-pixels (R pixel, G pixel, B pixel) will not have the same decay rate, or the use and duration of each area on the screen will not be the same, which will cause the problem of non-uniform aging on the display screen, especially the blue sub-pixel has a shorter decay period and more serious aging. Similarly, the LCD may have such a problem of inconsistent aging degree, and when the LCD, the OLED, and the like are applied to the electronic device with the foldable screen, the user may use different screens for different time periods when the electronic device with the foldable screen is in the folded state, and when the screen is completely unfolded, the user may find that the display effect of each screen is greatly different due to the inconsistent aging degree.

At present, in a compensation scheme for a folding screen, the compensation scheme is limited by a circuit structure of the folding screen, and effective compensation cannot be performed on an area to be compensated, for example, after an electronic device is bent, the electronic device can be divided into a main screen, a side screen (also called a bending area) and an auxiliary screen, generally, the service lives of users for the three screens are all inconsistent, so that the aging degrees of the main screen, the side screen and the auxiliary screen are inconsistent, a circuit of the main screen can be controlled independently, and circuits of the side screen and the auxiliary screen are controlled together, so that although the overall brightness difference between the main screen and the auxiliary screen can be reduced through circuit compensation, or the overall brightness difference between the main screen and the side screen can be reduced, the brightness difference between the side screen and the auxiliary screen cannot be compensated effectively.

The application provides a compensation method and electronic equipment, which are used for reducing the brightness difference among screen areas of the electronic equipment and enabling the display effects of different screen areas to be consistent.

In a first aspect, an embodiment of the present application provides a compensation method, which is applied to an electronic device having a display screen, where the display screen includes a first screen area, a second screen area, and a third screen area, where the second screen area and the third screen area are controlled by a same gamma parameter, and the method includes: the electronic equipment respectively determines the brightness of a first screen area, a second screen area and a third screen area at a first moment; the electronic equipment determines a first gamma parameter corresponding to the brightness of the first screen area at a first moment, sets a second gamma parameter of the second screen area and a second gamma parameter of the third screen area as the first gamma parameter, when the third screen area needs to display content, the electronic equipment adds a mask layer in the third screen area, and then the electronic equipment adjusts the transparency of the mask layer to be the first transparency according to the brightness difference value of the second screen area and the third screen area at the first moment.

In this way, the brightness of the three screen regions at the first moment can be determined conveniently in real time, so that the brightness difference of the three screen regions can be adjusted in real time.

In one possible design, the brightness of any one of the first, second, and third screen regions at a first time is determined using the following formula:

In one possible design, after determining the brightness of the first screen region, the second screen region, and the third screen region at the first time, respectively, before determining the first gamma parameter corresponding to the brightness of the first screen region at the first time, the method further includes: and determining that the brightness of the second screen area is greater than that of the first screen area and less than that of the third screen area. In this case, the luminance of the second screen region and the luminance of the third screen region, which have relatively large luminance, may be adjusted to reduce the difference between the luminance of the second screen region and the luminance of the third screen region, respectively, and the luminance of the first screen region.

In a possible design, the first gamma parameter corresponding to the brightness of the first screen region at the first time is determined, and the first gamma parameter corresponding to the brightness of the first screen region at the first time is determined according to a gray-scale value corresponding to the brightness of the first screen region at the first time and a first corresponding relationship, where the first corresponding relationship includes a corresponding relationship between the gamma parameter and the gray-scale value. This allows easy determination of the gamma parameter of the first screen area.

In one possible design, the method further includes: when the screen direction of the electronic equipment changes or the screen resolution changes, determining a first mask attribute corresponding to the changed direction or the changed resolution; the first mask attribute comprises the height and width of the display screen, the coordinates of a mask layer and the height and width of the mask layer; and adjusting the mask attribute of the mask layer to be the first mask attribute.

Therefore, when the brightness difference value between the third screen area and the second screen area changes, the transparency of the mask layer can be updated in time, the brightness difference between the screen areas can be reduced in time, and the display effects of different screen areas are consistent.

In one possible design, the mask layer is deleted when the third screen area is closed to display. Therefore, when the third screen area is not displayed, the mask layer is deleted, and the system overhead can be saved.

In one possible design, when the screen direction of the electronic device changes or the screen resolution changes, the resolution of the mask layer is adjusted according to the changed direction or the changed resolution. Therefore, the mask layer can adapt to the change of the third screen area, and the problem that the actual display area of the third screen area is not matched with the screen resolution is avoided.

In one possible design, when the electronic device starts a screen capture or recording function, if it is determined that the content to be captured includes a mask layer, the mask layer is deleted from the content to be captured, and the screen capture or recording function is performed on the content to be captured with the mask layer deleted.

Through the design, when the screen is played in the electronic equipment with consistent content screen brightness after screen capture or screen recording, the situation that the brightness of the area where the mask layer is located is darker and the brightness of other places is brighter can be avoided.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It should be apparent that the described embodiments are only a few embodiments of the present application, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

For example, the display screen includes a first screen region, a second screen region, and a third screen region, where the second screen region and the third screen region may be controlled by a same gamma parameter, and the control of the brightness by the same gamma parameter may also be achieved by controlling by a same driving circuit of the second screen region and the third screen region. Since the brightness of the second screen region and the third screen region is controlled by the same gamma parameter, so that the adjustment amount of the second screen region is the same as that of the third screen region, if there is a brightness difference between the second screen region and the third screen region, the brightness difference between the second screen region and the first screen region and the brightness difference between the third screen region and the first screen region can be reduced by controlling the brightness by the same gamma parameter, and the brightness difference between the second screen region and the third screen region cannot be reduced. In order to reduce the brightness difference between the screen regions included in the display screen, the following embodiments provide a compensation method for reducing the brightness difference between the screen regions of the electronic device, so that the display effects of different screen regions are consistent.

It should be noted that, in the embodiment of the present application, the brightness of each screen region refers to the actual brightness of the screen region. The difference between the luminance of the main screen and the luminance of the sub screen is taken as an example to explain, that is, when the luminance of the main screen is not consistent with the luminance of the sub screen, even if the same luminance parameter (for example, the luminance parameter of the main screen refers to the percentage of the actual luminance of the main screen to the maximum luminance (also referred to as the initial luminance) of the main screen when the main screen leaves the factory, which may be referred to as the luminance percentage for short) is set for the main screen and the sub screen, the luminance of the main screen and the luminance of the sub screen are not necessarily the same, for example, the maximum luminance of the main screen is 500nit and the maximum luminance of the sub screen is 400nit, the luminance parameter of the main screen and the luminance parameter of the sub screen are both set to 50% by the user, and actually, the luminance of the main screen is 250nit and the luminance of the sub screen is 200nit, so the luminance of the main screen and the luminance of the sub screen are not consistent. For convenience of description, the initial maximum brightness of the main screen, the sub-screen, and the side screen is used as an example, so that the brightness of the main screen, the sub-screen, and the side screen can be expressed by a brightness parameter, that is, a brightness percentage, unless otherwise specified.

The electronic device in the embodiment of the application can be a mobile phone, a tablet computer (pad), a notebook computer, and the like. The electronic device may be an electronic device having different screen areas (or display areas), and the different screen areas may be folded, stretched, or partially displayed. Taking the electronic device as an example of a mobile phone with a foldable screen, the foldable screen of the mobile phone may be an integrated flexible display screen, or may be a display screen composed of at least two rigid screens and a flexible screen located between the two rigid screens. The foldable screen provided by the embodiment of the present application is exemplified by including three parts, as shown in fig. 1a, 1b and 1c, the foldable screen may include a first screen 111, a second screen 112, and a bendable region 112 connecting the first screen 111 and the second screen 113.

The following describes shapes of the folding screen of the mobile phone in different states with reference to the drawings.

Fig. 1a shows a schematic shape of a cell phone when it is fully deployed. As shown in fig. 1a, when the mobile phone is unfolded, the housing 120 of the mobile phone is unfolded, and at the same time, the folding screen 110 is also unfolded. The foldable screen 110 may include a first screen 111, a bendable region 112, and a second screen 113, and when the foldable screen 110 of the mobile phone is completely unfolded, the first screen 111, the bendable region 112, and the second screen 113 are connected to form a whole screen, and at this time, the gravity sensor may detect that an included angle a between the first screen 111 and the second screen 113 is 180 ° (an actual folding angle may not reach 180 °, based on an actually reported folding angle).

In the embodiment of the present application, when the first screen 111 or the second screen 113 is rotated, the foldable screen 110 can be folded through the bendable region 112, when the foldable screen of the mobile phone is partially folded, see fig. 1b, and when the foldable screen of the mobile phone is fully folded, see fig. 1c.

As shown in fig. 1b and 1c, when the mobile phone is folded, the housing 120 of the mobile phone is also folded; at the same time, the folding screen 110 is also folded. While fig. 1b and 1c show the foldable screen 110 as being exposed when the phone is folded, it should be understood that the housing 120 may be exposed when the phone is folded, and the foldable screen 110 may be located inside, or a portion of the foldable screen 110 may be exposed.

In the process of the folding screen 110 of the mobile phone from being completely unfolded to being completely folded, an included angle a between the first screen 111 and the second screen 113 becomes smaller and smaller. As shown in fig. 1a, when the folding screen 110 is fully unfolded, the angle between the first screen 111 and the second screen 113 is 180 °. As shown in fig. 1b, when the foldable screen 110 of the mobile phone is partially folded, the gravity sensor 180E may detect that the angle between the first screen 111 and the second screen 113 is 40 °. As shown in fig. 1c, when the foldable screen 110 of the mobile phone is completely folded, the sensor detects that the included angle between the first screen 111 and the second screen 113 is 0 degree (the actual folding angle may not reach 0 °, based on the actually reported folding angle), and at this time, the first screen 111 and the second screen 113 are located on the exposed side when the mobile phone is folded.

When the mobile phone is folded, the second screen 113 faces the user for example, the second screen 113 faces the user and is called a main screen, the first screen 111 is called an auxiliary screen on the back, the bendable region 112 is called a side screen, when the mobile phone is folded, due to different use scenes and use habits of the user on the main screen and the auxiliary screen, for example, the user is used to use the main screen when the mobile phone is folded, and the auxiliary screen is in a screen-saving state, the different use time lengths of the main screen, the side screen and the auxiliary screen can be found after the mobile phone is used for a period of time, so that the problem that the aging degrees of the main screen, the side screen and the auxiliary screen are different can be caused.

The main screen is used for the most time generally, and the luminous efficiency of pixels is influenced due to the loss of display materials, so that the luminous materials of the main screen are aged the fastest, the service life of the auxiliary screen is shorter than that of the main screen, the side screen is a folding area and is not used for a long time, and the aging degree is the lowest. For example, taking the initial brightness of three screens as 100%, after a period of use, as shown in fig. 1d, the brightness of the main screen is 94.8%, the brightness of the sub-screen is 98.2%, and the brightness of the side screen is 100%. When the mobile phone is completely unfolded, the main screen, the side screen and the auxiliary screen form a screen, a user faces to the whole screen, and when the whole screen is displayed, the user can find the problem that the display brightness of different areas of the whole screen is inconsistent.

In the embodiment of the present application, a gamma (gamma) calibration mode may be adopted to compensate for the brightness difference between the main screen, the side screen, and the sub-screen, and it should be noted that, when the brightness of each screen is adjusted by adopting a gamma calibration mode for the electronic device with a foldable screen at present, the brightness is limited by the circuit structure, and the side screen can only be adjusted together with the main screen, or the side screen can only be adjusted together with the sub-screen. If the side screen rotates along with the main screen when the electronic device is folded, the side screen and the driving circuit of each pixel in the main screen can be controlled together, that is, the brightness of the main screen and the side screen can be adjusted simultaneously by controlling the driving circuit. If the side screen rotates along with the sub-screen when the electronic device is folded, the side screen and the driving circuit of each pixel in the sub-screen can be controlled together, that is, the brightness of the sub-screen and the side screen can be adjusted simultaneously by controlling the driving circuit. In the following embodiments, the side panel and the sub panel are adjusted together as an example.

Taking the compensation of the brightness difference between the main screen, the side screen and the sub screen shown in fig. 1d as an example, the brightness of the side screen and the sub screen is adjusted by gamma (gamma) calibration, for example, the brightness of the side screen and the sub screen in fig. 1d is respectively reduced by 3.4%, as shown in fig. 1e, the brightness of the side screen is 96.6%, and the brightness of the sub screen is 94.8%, that is, after gamma calibration, the brightness of the sub screen and the main screen are the same, but the brightness of the side screen cannot be the same as the brightness of the main screen and the sub screen.

Taking the luminance of the auxiliary screen as 98.2% and the luminance of the side screen as 100%, respectively reducing the luminance of the side screen and the luminance of the auxiliary screen by 3.4% by using a gamma calibration method, the process is as follows: the value of the gamma parameter is 2.1-2.3, which is corresponding to the gray scale (0-255), and the gray scale represents the brightness level. For example, taking the initial brightness of the main screen as 500nit (corresponding to a gray level value of 255) and the initial brightness of the sub-screen as 400nit as an example, after the electronic device is used for a period of time, the brightness of the main screen is reduced to 400nit, the corresponding gray level value is 204, and the gamma parameter of the main screen can be determined to be 2.26 according to the corresponding relationship between the gamma parameters (2.1-2.3) and the gray levels (0-255); the brightness of the auxiliary screen is reduced to 300nit, the corresponding gray scale value is 191, and the gamma parameter of the main screen can be determined to be 2.25 according to the corresponding relation between the gamma parameters (2.1-2.3) and the gray scales (0-255). It should be noted that the gray scale value of each screen is related to the initial brightness of the screen, and the gray scale values corresponding to the brightness at a certain time may be different for two screens with different initial brightness.

It should be noted that the brightness of the sub-screen and the side-screen is controlled by the same gamma parameter, and when the brightness of the side-screen and the sub-screen needs to be adjusted together in a gamma calibration manner, the brightness of the sub-screen and the brightness of the side-screen are adjusted at the same time, that is, the adjustment amount of the brightness of the sub-screen and the brightness of the side-screen are the same. For example, when the gamma parameter corresponding to the luminance of the sub-screen is adjusted to 2.28, the luminance of the sub-screen is reduced to 92% and the luminance is reduced by 3% in total, for example, the luminance of the sub-screen is 95%, the luminance of the side screen is 98%, and the gamma parameter corresponding to the luminance of the sub-screen is 95%, the luminance of the side screen is also reduced by 3%, that is, the luminance of the side screen is 95%.

The method comprises the steps that gamma parameters corresponding to the current brightness of a main screen and the current brightness of an auxiliary screen are stored in a configuration file of an internal memory, a first gamma parameter corresponding to the current brightness (94.8%) of the main screen can be determined according to a gray level value corresponding to the current brightness of the main screen and the corresponding relation between the gamma parameter and the gray level value, then a storage position of a second gamma parameter corresponding to the current brightness (96.6%) of the auxiliary screen is read from the configuration file of the internal memory, the first gamma parameter is written into the storage position of the second gamma parameter in the configuration file, namely the first gamma parameter is used for replacing the second gamma parameter, the brightness of the auxiliary screen is reduced to be consistent with that of the main screen, namely reduced to 94.8%, the brightness of the auxiliary screen is reduced by 3.4%, and the brightness of the side screen is reduced by 3.4%.

The embodiment of the application provides a compensation method, which is used for performing brightness compensation on a screen with low brightness attenuation when aging degrees of a plurality of screens (such as a main screen, a side screen and an auxiliary screen) included in an electronic device are different, for example, brightness differences exist among the main screen, the auxiliary screen and the side screen, so that brightness display effects of the screens are consistent.

Taking the example that the brightness of the main screen is greater than that of the auxiliary screen, and the brightness of the auxiliary screen is greater than that of the side screen, the embodiments of the present application have various possible ways to implement brightness compensation for the screen with low brightness attenuation, which may include, but are not limited to, the following:

in the mode 1, gamma calibration can be performed on the side screen and the auxiliary screen together, so that the brightness of the side screen and the brightness of the auxiliary screen can be reduced by the same brightness value, for example, the brightness of the auxiliary screen is reduced to be consistent with the brightness of the main screen, but the brightness of the side screen is still higher than the brightness of the main screen, and the brightness of the side screen can be adjusted by combining a mask layer, wherein the mask layer is used for continuously reducing the brightness of the side screen to be consistent with the brightness of the main screen. For convenience of description, the layer used for adjusting the brightness is referred to as a mask layer in this embodiment of the application, and in other possible embodiments, other names may also be used, which are not specifically limited.

Taking the foldable screen shown in fig. 1d as an example, gamma calibration is performed on the side screen and the sub-screen, so that the luminance of both the side screen and the sub-screen can be reduced by 3.4%, that is, the luminance of the side screen is reduced by 96.6%, and the luminance of the sub-screen is reduced by 94.8%. And a mask layer is created for the side screen, and the brightness of the side screen can be continuously reduced by 1.8% by adjusting the transparency of the mask layer to be 1.8%, namely the brightness of the side screen is reduced to be 94.8%. Therefore, the brightness difference among the three screens can be reduced by combining the gamma calibration and the mask layer, so that the display effects of the three screens are consistent.

And 2, respectively creating mask layers for the auxiliary screen and the side screen, reducing the brightness of the side screen to be consistent with the brightness of the main screen by adjusting the transparency of the mask layer of the side screen, and reducing the brightness of the auxiliary screen to be consistent with the brightness of the main screen by adjusting the transparency of the mask layer of the auxiliary screen.

Taking the folding screen shown in fig. 1d as an example, the luminance of the main screen is 94.8%, the luminance of the side screen is 100%, the luminance of the sub-screen is 98.2%, a mask layer is created and set to a transparency of 5.2% for the side screen, and a mask layer is created and set to a transparency of 3.4% for the sub-screen, so that the luminance of both the sub-screen and the sub-screen can be reduced to 94.8%. The brightness of the two screens with higher brightness can be reduced by adjusting the transparency through the mask layer, so that the brightness difference among the three screens is reduced, and the display effects of the three screens are consistent.

The mask layer is covered on the initial layer of the display picture, namely, the brightness compensation is realized by setting the transparency of the mask layer on the upper layer of the initial layer, the value of the transparency is set to be 0 percent, which represents that the mask layer is completely transparent, the value of the transparency is set to be 100 percent, which represents that the mask layer is completely opaque, the value of the transparency is set between 0 percent and 100 percent, and the larger the value is, the lower the transparency is.

It should be noted that, in the mask layer related in the embodiment of the present application, adjustment of the screen brightness is mainly achieved by changing the transparency, and the mask layer may be used by being superimposed on a layer with another function, so that the function of the layer with the other function is not affected. If the mask layer is superposed on other layers and the transparency value of the mask layer is greater than 0, only the brightness of the area where the mask layer exists is affected.

The window manager is used for managing window programs. The window manager can obtain the size of the display screen, judge whether a status bar exists, lock the screen, intercept the screen and the like.

The content provider is used to store and retrieve data and make it accessible to applications. The data may include video, images, audio, calls made and received, browsing history and bookmarks, phone books, etc.

The view system includes visual controls such as controls to display text, controls to display pictures, and the like. The view system may be used to build applications. The display interface may be composed of one or more views. For example, the display interface including the short message notification icon may include a view for displaying text and a view for displaying pictures.

The phone manager is used to provide the communication functions of the handset 100. Such as management of call status (including on, off, etc.).

The resource manager provides various resources for the application, such as localized strings, icons, pictures, layout files, video files, and the like.

The notification manager enables the application to display notification information in the status bar, can be used to convey notification-type messages, can disappear automatically after a short dwell, and does not require user interaction. Such as a notification manager used to notify download completion, message alerts, etc. The notification manager may also be a notification that appears in the form of a chart or scroll bar text at the top status bar of the system, such as a notification of a background running application, or a notification that appears on the screen in the form of a dialog window. For example, prompting text information in the status bar, sounding a prompt tone, vibrating the electronic device, flashing an indicator light, etc.

And the screen loss modeling module is used for calculating the position, the compensation value and the transparency (Alpha value) of the area to be compensated in each screen.

And the mask image layer drawing module is used for drawing a mask image layer for the screen needing brightness compensation and setting an Alpha value for the mask image layer.

For clarity in describing the functionality of the screen loss modeling module, the mask layer rendering module, and the surface manager, further description is provided below in conjunction with FIG. 3 b. As shown in fig. 3 b:

and the screen loss modeling module can periodically read the use data and the aging formula of each screen in Flash in the hardware layer. Wherein, the aging formula can be expressed as:

where, lum is the screen brightness after the time t, lum _ init is the maximum brightness of the screen, t is the accumulated value of the historical use time (i.e. the time when the screen is in the bright screen state), t is ₀ And (2) setting the theoretical maximum light-emitting duration of the screen area, wherein Lev is the brightness of a light-emitting unit with the maximum brightness in the OLED material of the screen at the current moment, lev _ max is the maximum brightness of the light-emitting unit in the OLED material of the screen, and all brightness-related parameters in the formula (1) are actual brightness. Wherein γ, k, and β are collectively referred to as fabrication process parameters, specifically, γ is a parameter related to maximum brightness, k is a constant determined by the OLED process, and β is a parameter related to the OLED material and the fabrication process.

For example, the brightness of the light-emitting units in the screen is stored in a register, and as the service time of the screen (i.e. the time of being on the bright screen) is prolonged, the brightness of each light-emitting unit stored in the register is also attenuated, and the brightness of each light-emitting unit can be read from the register at any time, for example, taking the main screen as an example, the brightness of each light-emitting unit can be read from the register at the time of factory shipment (i.e. any time before the main screen is on the bright screen for the first time), and a maximum brightness is determined as the maximum brightnessLev _ max in equation (1); the luminance of each light emitting unit included in the main screen may be read at a first time, and then a maximum luminance may be determined from each light emitting unit as the value of Lev in formula (1), γ, k, β, t ₀ The Lum _ init is a known constant when being delivered out of a factory and is stored in a register; t is the total duration of the screen area in a bright screen state from the factory time to the first time; then, the brightness Lum of the main screen can be calculated according to the formula (1).

In the above formula (1), the time t is the time when the screen is in the bright screen state, and the brightness is calculated by counting the time when the screen is in the bright screen state, and the brightness and the display color are not considered, in other examples, the use time of the screen respectively at different brightness or different color may also be counted to determine the brightness of the screen after the screen decays in the use time t.

The screen loss modeling module can also respectively calculate the actual brightness of each screen after the brightness of each screen is attenuated by the time t according to the use data of each screen and the aging formula.

And calculating the brightness difference values of the main screen, the auxiliary screen and the side screen respectively by taking the screen with the lowest actual brightness as reference so as to adjust the brightness of the auxiliary screen and the side screen and enable the brightness of the side screen and the brightness of the auxiliary screen to be consistent. Taking the above mode 1 as an example, gamma calibration is performed on the secondary screen and the side screen first to make the brightness of the secondary screen consistent with that of the main screen, then a mask layer is added to the side screen, and then an Alpha value required to be set in the mask layer of the side screen is calculated.

The system comprises a mask layer drawing module, a surfefinger and a frame buffer (frame buffer), wherein the mask layer drawing module is used for drawing a mask layer, an Alpha value of the mask layer is set, then the mask layer is transmitted to the surfflinger, the surfflinger synthesizes the mask layer received from the mask layer drawing module with an initial layer, synthesized data are sent to an LCD through the frame buffer for displaying, then the synthesized data can be displayed on a display screen, and human eyes can see that the display brightness of the whole screen reaches consistency.

The mask image layer drawing module can comprise a resolution self-adaptive module, a screen turning direction self-adaptive module, a screen capture self-adaptive module, a screen recording self-adaptive module and an explicit self-adaptive module. The resolution self-adaptive module can adjust the resolution of the mask layer when the system resolution is changed so as to ensure that the area displayed on the physical position of the mask layer on the whole display screen is unchanged.

The screen rotation direction self-adaptive module can be used for adjusting the direction of the mask layer when the screen rotates, so that the physical position of the compensated region on the whole display screen is unchanged.

And the screen capture self-adaptive module is used for traversing all layers when a screen capture event is received, and capturing the interface formed by the layers except the mask layer.

And the screen recording self-adaptive module is used for traversing all layers when receiving a screen recording event and intercepting an interface formed by the layers except the mask layer.

And the explicit adaptive module is used for sending the data corresponding to the layers except the mask layer to the external display equipment for display when the content to be displayed is sent to the external display equipment.

The Android Runtime comprises a core library and a virtual machine. The Android runtime is responsible for scheduling and managing an Android system. The core library comprises 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 media library supports a variety of commonly used audio, video format playback and recording, and still image files, among others. The media library may support a variety of audio-video encoding formats, such as MPEG4, h.264, MP3, AAC, AMR, JPG, PNG, and the like. The three-dimensional graphic processing library is used for realizing three-dimensional graphic drawing, image rendering, synthesis, layer processing and the like. The 2D graphics engine is a drawing engine for 2D drawing.

The kernel layer is a layer between hardware and software. The kernel layer at least includes a frame buffer (frame buffer), a display driver, a sensor driver, an audio driver, a camera driver, a display subsystem (DSS) driver, and the like, which is not limited in this embodiment.

For ease of understanding, a specific example of the compensation of the brightness of each screen in the above mode 1 will be described below with reference to fig. 3 b.

In the above mode 1, gamma calibration is performed on the side screen and the sub-screen with higher brightness in fig. 1d, that is, the brightness of both the side screen and the sub-screen is reduced by 3.4% by means of gamma calibration, that is, the brightness of the side screen is reduced to 96.6%, and the brightness of the sub-screen is reduced to 94.8%. Then, a mask layer is created for the side screen, and the brightness of the side screen can be continuously reduced by 1.8% by adjusting the transparency of the mask layer, that is, the brightness of the side screen is reduced to 94.8%. The process of creating the mask layer is described below by taking the creation of the mask layer of the side screen as an example.

Please refer to fig. 4, which is a timing diagram illustrating a process of creating a mask layer according to an embodiment of the present application. As shown in fig. 4, the method mainly comprises the following steps:

in step 401, a surface manager (surfflecger) initializes the screen display status of the side screen. For example, the screen display state may be display, or, the display may be turned off.

Step 402, a mask layer Display Thread (Thread) is created through an SF decoupling function (surfaceflexerex).

At step 403, the mask layer display thread notifies the display engine manager process to create an object that includes relevant information for determining whether the mask layer properties are supported.

Step 404, the mask layer display thread acquires the object.

Step 405, the mask layer display thread determines whether the side screen supports the result of the mask layer characteristics according to the obtained object.

In step 406, the mask layer display thread returns a result (whether the side screen supports the mask layer characteristics) to the SF decoupling function. And if the result received by the SF decoupling function is that the side screen supports the mask layer characteristics, starting the mask thread after receiving the completion of the starting of the main thread.

Step 407, the surface manager notifies the SF decoupling function: the main thread starts to complete.

In step 408, the SF decoupling function starts the masking thread.

And step 409, starting and running a mask layer display thread.

Step 410, the mask layer display thread obtains the mask graphic display information from the SF.

In step 411, the mask layer display thread acquires display information.

And step 412, the mask layer display thread determines layer parameters according to the display information.

In step 413, the mask layer display thread creates an SF client (surface component client) that can act as a proxy object for communicating with the surface manager.

In step 414, the SF client returns an SF client identifier to the mask layer display thread.

Step 415, the mask layer display thread creates a mask layer in the SF client.

In step 416, the sf client returns a handle to the mask layer display thread.

Step 417, the mask layer display thread sets layer parameters of the mask layer at the SF client through the handle, where the layer parameters may be resolution, direction, size, transparency, and the like of the mask layer.

In step 418, the sf client returns the layer parameter setting result to the mask layer display thread.

And step 419, the display thread of the mask layer creates a callback function.

In step 420, the callback function creation is complete.

In step 421, the mask layer display thread registers a callback function with the display engine manager process. And the mask layer display thread acquires the layer parameters of the side screen from the display engine manager process in a mode of registering a callback function.

Step 422, the mask layer display thread waits for a signal trigger. Specifically, when the mask layer display thread receives a signal triggered by an event such as a change in screen direction or a change in resolution, the mask layer display thread triggers resetting of the layer parameters of the mask layer.

Taking the luminance of the side screen as an example of 96.6%, after the mask layer (the initial transparency is 0%, i.e., completely transparent) is created for the side screen, the luminance of the side screen may be continuously reduced by 1.8% by adjusting the transparency of the mask layer so as to adjust the luminance of the side screen to be consistent with the sub-screen (the luminance is 94.8%), and then the setting of the mask layer may be set to 1.8% so as to change the transparency to 1.8%. Referring now to FIG. 5, a schematic diagram of a process for changing the transparency of the mask layer is shown. As shown in fig. 5, the method mainly comprises the following steps:

step 501, the display engine manager (display engine manager) process calls a callback function (display engine callback).

Step 502, the display engine manager process notifies the mask layer display thread (meta layer display: thread) by calling the onevent class in the callback function: and the layer parameters of the mask layer.

Step 503, the mask layer display thread checks whether the transparency in the layer parameters of the mask layer changes according to the obtained layer parameters of the mask layer.

Step 504, when the transparency of the mask layer display thread changes, the changed transparency is sent to the SF client, for example, the transparency of the mask layer before being changed is 0%, and the transparency after being changed is 1.8%.

And 505, the SF client updates the transparency of the mask layer.

When the screen direction or the screen resolution of the mobile phone changes, the size or the dimension of the mask layer also needs to be changed so as to adapt to the size of the screen, and therefore the whole screen can be shielded by the mask layer, and the consistency of the whole brightness of the screen can be realized. As shown in table 1 below, the mask attributes (wd, hd, x, y, w, h) of the side screen corresponding to different resolutions and directions are shown, where wd is the width of the entire screen of the mobile phone, hd is the height of the entire screen of the mobile phone, (x, y) is the coordinates of the mask layer, w is the width of the mask layer, and h is the height of the mask layer.

Table 1 shows the mask attributes of the side panels corresponding to different resolutions and directions

Resolution ratio	1100*1240(HD+)	1650*1860(FHD+)	2200*2480(WQHD+)
				Direction 0	(1240,1100,0,574,1240,80)	(1860,1650,0,861,1860,120)	(2480,2200,0,1148,2480,160)
Direction 3	(1100,1240,446,0,80,1240)	(1650,1860,669,0,120,1860)	(2200,2480,892,0,160,2480)
				Direction 2	(1240,1100,0,446,1240,80)	(1860,1650,0,669,1860,120)	(2480,2200,0,892,2480,160)
Direction 1	(1100,1240,574,0,80,1240)	(1650,1860,861,0,120,1860)	(2200,2480,1148,0,160,2480)

Table 1 shows mask attributes of mask layers corresponding to the mobile phone screen in each direction when the resolution of the mobile phone screen is 1100 × 1240, 1650 × 1860, 2200 × 2480, respectively, and the example of the resolution of the mobile phone screen is 2200 × 2480 is given, and when the direction of the mobile phone screen is changed, the mask attributes of the mask layers are also changed. As shown in fig. 6, the screen direction of the mobile phone is direction 1, when the screen of the mobile phone is rotated by 90 ° to the left, the screen direction of the mobile phone is direction 0, when the screen of the mobile phone is rotated by 90 ° to the left, the screen direction of the mobile phone is direction 3, and when the screen of the mobile phone is rotated by 90 ° to the left, the screen direction of the mobile phone is direction 2. When the mobile phone screen continues to rotate 90 degrees to the left, the screen direction of the mobile phone is direction 1. For example, the direction of the screen of the mobile phone is direction 1 as an example, in this case, the width of the mobile phone screen is 2200, the height is 2480, the coordinate position (x, y) of the mask layer of the corresponding side screen is (1148, 0), the width of the mask layer is 160, and the height is 2480.

In the following, how to change the resolution and/or size of the mask layer when the direction or resolution of the mobile phone screen changes is described in detail. As shown in fig. 7, the method mainly includes the following steps:

in step 701, the application/other SF client sends an event that the screen direction/resolution changes to an SF decoupling function (surface flanger Ex).

In step 702, the SF decoupling function informs the mask layer display thread (meta layer display: thread) of the occurrence of the event by setting a transaction status function.

Step 703, the mask layer display thread checks whether the resolution and direction of the screen change, and obtains a check result.

Step 704, the mask layer display thread sends the check result to the SF decoupling function.

Step 705, the sf decoupling function sends the inspection result to the surface manager (surface flicker).

In step 706, the surface manager updates the resolution and/or size of the mask layer if the checking result indicates that the resolution and/or screen direction has changed. Of course, the surface manager does not update the resolution and/or size of the mask layer if it determines that the resolution and/or screen orientation has not changed as a result of the check.

The following describes a process of layer resolution caused by a change in the physical state of the mobile phone screen, taking an example of changing the direction of the mobile phone screen from the unfolded state to the folded state. As shown in fig. 8, the method mainly includes the following steps:

step 801, the mobile phone is in a full screen display state.

Step 802, a sensor (sensor) detects that the mobile phone is changed from the unfolded state to the folded state, and sends a notification that the folded state of the mobile phone is changed to a sensor manager/state service. Thereafter, step 803 and step 808 are performed, respectively.

At step 803, the sensor state manager notifies a surface manager (surfflinger) to set the switch screen state.

At step 804, the surface manager notifies the DSS driver to set the switch screen state.

Step 805, DSS driver delays for several frames, switching to full screen display by DSC.

In step 806, the surface manager notifies the mask layer display thread (meta layer display: thread) to check for the collapsed state.

In step 807, the mask layer display thread waits for the completion of Window Manager (WMS) processing.

At step 808, the sensor state manager notifies a display manager (display manager service) to set the switch screen state.

Step 809, the display manager notifies the window manager of the new display resolution.

At step 810, the window manager freezes/notifies the application to switch to the new display resolution. Where "/" denotes or.

In step 811, the window manager notifies the display manager to apply the new display resolution to the newly sized rendered layer/unfreeze screen.

At step 812, the display manager notifies the surface manager to set a new display position.

In step 813, the surface manager notifies the mask layer display thread WMS that the process is complete.

Step 814, the mask layer display thread creates/deletes layers. For example, taking the example that the side screen is provided with the mask layer, when full-screen display needs to be switched to partial display, for example, the main screen is partially displayed, the sub-screen and the side screen do not display, and at this time, the mask layer corresponding to the side screen needs to be deleted. For another example, when switching from the partial display main screen to the partial display side screen, a mask layer needs to be created for the side screen.

At step 815, the surface manager notifies the hardware composition abstraction layer (HWC) of the new display location.

In a screen capture scene, in order not to affect the authenticity of the content captured and displayed by the mobile phone, whether a mask layer exists in all layers to be captured or not can be determined, and when the mask layer exists in all the layers to be captured, the content of other layers except the mask layer is captured.

The following describes in detail how to implement the specific process of the screen capture function in the screen capture scene with reference to fig. 9. As shown in fig. 9, the method mainly includes the following steps:

at step 901, a surface manager (surfefinger) receives a trigger screen capture event.

Step 902, the surface manager traverses all layers to be screenshot, and sends all layers to the renderer.

In step 903, the surface manager sends the layer snapshot to be subjected to screen capture to an SF decoupling function (surfefringerrex).

In step 904, the SF decoupling function notifies the mask layer display thread (meta layer display: thread) to determine if a mask layer exists.

Step 905, the mask layer display thread determines whether a mask layer exists.

And step 906, the mask layer display thread sends the determined result to the SF decoupling function.

In step 907, when the SF decoupling function informs the surface manager to draw the layer to be subjected to screen capturing, the mask layer is skipped over, and drawing processing is not performed.

In a screen recording scene, the content recorded for the mobile phone 100 may be used for playing in an electronic device with consistent screen brightness, and if the mask layer of the side screen of the mobile phone 100 is also recorded, when the recorded content is played in the electronic device with consistent screen brightness, the brightness of the area where the mask layer is located is darker and the brightness of other places is brighter. For another example, in a scenario where the mobile phone 100 is connected to multiple displays, the screen of the mobile phone 100 is used as the main display, and the screens of other mobile phones are used as non-main displays, and if the screen brightness of the non-main displays is consistent, when the masking layer of the side screen of the mobile phone 100 is transmitted to the non-main displays for displaying, the brightness of the area where the masking layer is located is dark, and the brightness of other areas is slightly bright.

The following describes in detail how to implement the specific process of the screen capture function in the screen capture scenario with reference to fig. 10. As shown in fig. 9, the method mainly comprises the following steps:

at step 1001, the application notifies a surface manager (surfefinger) to enter a screen-recording or multi-display scene.

At step 1002, the surface manager calculates the visible area of each layer.

Step 1003, the surface manager traverses all layers, and adds the layer with the intersection of the visible area of each layer and the current display area to the layer set of the corresponding display.

In step 1004, the surface manager notifies an SF decoupling function (surfefringernex) to determine whether a mask layer exists in the layer set corresponding to each display.

In step 1005, the sf decoupling function notifies a mask layer display thread (meta layer display: thread) to determine whether a mask layer exists in the layer set corresponding to each display.

In step 1006, the mask layer display thread determines whether a mask layer exists.

And 1007, the mask layer display thread sends the determined result to the SF decoupling function.

In step 1008, the sf decoupling function notifies the surface manager to determine the layer sets of all displays, and the masked layers in the layer sets of any non-main display (virtual displays such as peripheral displays and screen recording) are skipped.

By the above example, in scenes such as screen recording and multi-display, display on a display (or a display screen) with uniformity in screen brightness is not affected by skipping the mask layer.

Referring to fig. 11, a flowchart of a compensation method provided by an embodiment of the present application is exemplarily shown, where the method is performed by an electronic device having a display screen, and the display screen includes a first screen area, a second screen area, and a third screen area having a same driving circuit structure as the second screen area, and the method includes the following steps:

in step 1101, the electronic device determines the brightness of the first screen area, the second screen area and the third screen area at a first time respectively.

In step 1102, the electronic device determines a first gamma parameter corresponding to the brightness of the first screen area at a first time.

In step 1103, the electronic device sets the second gamma parameters of the second screen area and the third screen area as the first gamma parameters.

Step 1104, when the third screen area needs to display the content, the electronic device adds a mask layer in the third screen area.

In step 1105, the electronic device adjusts the transparency of the mask layer to a first transparency according to the brightness difference between the second screen area and the third screen area at the first time.

In the step 1105, the brightness difference between the second screen region and the third screen region at the first time is the same as the brightness difference between the second screen region and the third screen region after being adjusted to the first gamma parameter. That is, step 1105 may be replaced with: and adjusting the transparency of the mask layer to be the first transparency according to the brightness difference value of the second screen area and the third screen area after the first gamma parameter is set.

In the embodiment of the application, because the brightness of the second screen area and the third screen area is controlled by the same gamma parameter, the brightness of the second screen area and the third screen area can be reduced by adjusting the same gamma parameter, and the brightness of the second screen area can be adjusted to be consistent with the brightness of the first screen area by replacing the second gamma parameter of the second screen area with the first gamma parameter corresponding to the first screen area, and the brightness of the third screen area is adjusted to be the same as the brightness of the second screen area, so that a brightness difference still exists between the third screen area and the first screen area, then a mask layer is added to the third screen area, the transparency of the mask layer is adjusted to be the first transparency according to the brightness difference of the second screen area and the third screen area at the first moment, and the brightness of the third screen area can be adjusted to be the same as that of the second screen area, so that the brightness difference between the screen areas of the electronic device can be reduced, and the display effects of different screen areas are consistent.

the method includes the steps that the Lum is the screen brightness of the screen area from the factory time to the first time, the Lum _ init is the maximum brightness of the screen area at the factory time, t is the total duration of the screen area in a bright screen state from the factory time to the first time, and t is the total duration of the screen area in the bright screen state from the factory time to the first time ₀ The theoretical maximum light emitting duration of the screen area is obtained, lev is the brightness of the light emitting unit with the maximum brightness at the first moment in the light emitting units included in the screen area, and Lev _ max is the light emitting unit with the maximum brightness at the factory moment in the light emitting units included in the screen area; gamma is a first manufacturing process parameter, k is a second manufacturing process parameter, and beta is a third manufacturing process parameter.

For example, the specific manner of determining the brightness of the first screen region, the second screen region and the third screen region at the first time can be seen in the above formula (1).

In one possible design, a first gamma parameter corresponding to the brightness of the first screen region at the first time is determined, and the first gamma parameter corresponding to the brightness of the first screen region at the first time is determined according to a gray-scale value corresponding to the brightness of the first screen region at the first time and a first corresponding relationship, where the first corresponding relationship includes a corresponding relationship between the gamma parameter and the gray-scale value. This allows easy determination of the gamma parameter of the first screen area.

In one possible design, setting the second gamma parameter of the second screen region and the third screen region as the first gamma parameter may include: reading storage locations of second gamma parameters of the second screen area and the third screen area from a configuration file in an internal memory; deleting the second gamma parameter from the storage location of the second gamma parameter and writing the first gamma parameter into the storage location of the second gamma parameter.

In a possible design, before adding the mask layer to the third screen area, the method may further include: and determining that the third screen area supports the mask layer characteristics. That is, in the case where the third screen region supports the mask layer characteristics, the mask layer is added; in the case where the third screen region does not support the mask layer characteristics, no operation is performed.

In one possible design, before the electronic device adds the mask layer to the third screen area, the method may further include: acquiring display information of a third screen area; determining layer parameters of the mask layer according to the display information of the third screen area; the layer parameters comprise one or more of resolution, direction, size and transparency; after adding the mask layer in the third screen area, the method may further include: and setting layer parameters of the mask layer.

In one possible design, the mask layer is deleted when the third screen area is closed to display. Therefore, the mask layer is deleted when the third screen area is not displayed, and the system overhead can be saved.

In one possible design, when the electronic device starts a screen capture or recording function, if it is determined that the content to be captured includes a mask layer, the mask layer is deleted from the content to be captured, and the screen capture or recording function is performed on the content to be captured with the mask layer deleted. Therefore, when the content screen after screen capture or screen recording is played in the electronic equipment with consistent brightness, the situation that the brightness of the area where the mask layer is located is darker and the brightness of other places is brighter can be avoided.

In one possible design, when the electronic device needs to share display content with the external display, if it is determined that the content to be shared includes a mask layer, the mask layer is deleted from the content to be shared, and the content to be shared with the deleted mask layer is shared with the external display. Therefore, the situation that when the shared content is played by the peripheral display with the consistent screen brightness, the brightness of the area where the mask layer is located is relatively low, and the brightness of other places is relatively high can be avoided.

Referring to fig. 12, a flowchart of another compensation method provided by an embodiment of the present application is exemplarily shown, where the method is performed by an electronic device having a display screen, and the display screen includes a first screen area, a second screen area, and a third screen area, where the second screen area and the third screen area are controlled by a same gamma parameter, and the method includes the following steps:

step 1201, the electronic device determines the brightness of the first screen area, the second screen area and the third screen area at a first moment respectively.

Step 1202, when the second screen area needs to display the content, adding a first mask layer in the second screen area, and adjusting the transparency of the first mask layer to a second transparency according to a first brightness difference value of the first screen area and the second screen area at a first moment.

Step 1203, when the third screen area needs to display the content, adding a second mask layer in the third screen area, and adjusting the transparency of the second mask layer to a third transparency according to a second brightness difference between the first screen area and the third screen area at the first time.

In one possible design, determining the brightness of the first screen region, the second screen region, and the third screen region at the first time point respectively includes: and determining the brightness of the first screen area, the second screen area and the third screen area at a first moment according to the initial brightness of the first screen area, the second screen area and the third screen area, the total duration of a bright screen state and manufacturing process parameters. In this way, the brightness of the three screen regions at the first moment can be determined conveniently in real time, so that the brightness difference of the three screen regions can be adjusted in real time.

the method includes the steps that the Lum is the screen brightness of the screen area from the factory time to the first time, the Lum _ init is the maximum brightness of the screen area at the factory time, t is the total duration of the screen area in a bright screen state from the factory time to the first time, and t is the total duration of the screen area in the bright screen state from the factory time to the first time ₀ The theoretical maximum light emitting duration of the screen area is obtained, lev is the brightness of the light emitting unit with the maximum brightness at the first moment in the light emitting units included in the screen area, and Lev _ max is the light emitting unit with the maximum brightness at the factory moment in the light emitting units included in the screen area; gamma is the first systemThe manufacturing process parameter, k is the second manufacturing process parameter, and β is the third manufacturing process parameter.

For example, the specific manner of determining the brightness of the first screen region, the second screen region and the third screen region at the first time may be referred to in formula (1) and related contents thereof, and details are not described here again.

In one possible design, after determining the brightness of the first screen region, the second screen region, and the third screen region at the first time point respectively, the method further includes: and determining that the brightness of the second screen area is greater than that of the first screen area and less than that of the third screen area. In this case, the luminance of the second screen region and the luminance of the third screen region, which have relatively large luminance, may be adjusted to reduce the difference between the luminance of the second screen region and the luminance of the third screen region, respectively, and the luminance of the first screen region.

In one possible design, before adding the first mask layer to the second screen region, the method may further include: and determining that the second screen area supports the mask layer characteristics. That is, in the case where the third screen region supports the mask layer characteristics, the first mask layer is added; in the case where the third screen region does not support the mask layer characteristics, no operation is performed.

In one possible design, adjusting the transparency of the first mask layer to a second transparency according to a first brightness difference between the first screen area and the second screen area at a first time includes: determining a first percentage of the first brightness difference value in the initial brightness of the second screen area according to the first brightness difference value of the first screen area and the second screen area at the first moment; taking the first percentage as a second transparency; and adjusting the transparency of the first mask layer to be a second transparency. By setting the first luminance difference value between the first screen region and the second screen region to be a first percentage of the initial luminance of the second screen region as the second transparency, the luminance of the second screen region can be reduced by the first luminance difference value, thereby achieving reduction of the luminance of the second screen region to be consistent with the first screen region.

In a possible design, before adding the first mask layer to the second screen area, the method may further include: acquiring display information of a second screen area; determining layer parameters of the first mask layer according to the display information of the second screen area; the layer parameters comprise one or more of resolution, direction, size and transparency of the first mask layer; after adding the first mask layer to the third screen area, the method may further include: and setting layer parameters of the first mask layer.

In one possible design, the method further includes: when determining that the layer parameters of the first mask layer change, determining the layer parameters after the first change; and setting a first layer parameter of the first mask layer according to the first changed layer parameter. Therefore, when the layer parameters of the first mask layer change, the layer parameters of the first mask layer can be updated in time.

In one possible design, the method may further include: when the brightness difference value between the second screen area and the first screen area is determined to be changed, determining the percentage of the changed brightness difference value in the initial brightness of the second screen area as a fourth transparency; and adjusting the transparency of the first mask layer to be a fourth transparency. Therefore, when the brightness difference value between the first screen area and the second screen area changes, the transparency of the first mask layer of the second screen area can be updated in time, the brightness difference between the screen areas can be reduced in time, and the display effects of different screen areas are consistent.

In one possible design, adjusting the transparency of the second mask layer to a third transparency according to a second brightness difference between the first screen area and the third screen area at the first time includes: determining a second percentage of the second brightness difference value in the initial brightness of the third screen area according to the second brightness difference value of the first screen area and the third screen area at the first moment; taking the second percentage as a third transparency; and adjusting the transparency of the mask layer to a third transparency. By taking the second brightness difference value between the first screen area and the third screen area as a second percentage of the initial brightness of the third screen area, as the third transparency, the brightness of the third screen area can be reduced by the second brightness difference value, thereby achieving the purpose of reducing the brightness of the third screen area to be consistent with the first screen area.

In one possible design, before adding the second mask layer to the third screen area, the method may further include: acquiring display information of a third screen area; determining layer parameters of a second mask layer according to the display information of the third screen area; the layer parameters comprise one or more of resolution, direction, size and transparency of the second mask layer; after adding the second mask layer to the third screen area, the method further includes: and setting layer parameters of the second mask layer.

In one possible design, the method further includes: when the screen direction of the electronic equipment changes or the screen resolution changes, determining a second mask attribute corresponding to the changed direction or the changed resolution; the second mask attribute comprises the height and the width of the display screen, the coordinates of the second mask layer and the height and the width of the second mask layer, and the electronic equipment adjusts the mask attribute of the second mask layer into the second mask attribute. Therefore, when the screen direction of the electronic device changes or the screen resolution changes, the mask attribute of the second mask layer is adaptively adjusted, so that the second mask layer can adapt to the change of the third screen area.

In one possible design, when the second screen area is closed to display, the first mask layer is deleted; and when the third screen area is closed to display, deleting the second mask layer. In this way, when any one of the second screen area and the third screen area is not displayed, the mask layer corresponding to the corresponding screen area is deleted, so that the system overhead can be saved.

In one possible design, when the screen direction of the electronic device changes or the screen resolution changes, the resolutions of the first mask layer and the second mask layer are respectively adjusted according to the changed direction or the changed resolution, so that the mask layers can adapt to the resolution change of the corresponding screen areas, and the problem that the actual display areas of the screen areas are not matched with the screen resolution is avoided.

In one possible design, when the electronic device starts a screen capturing or recording function, if the content to be captured includes a first mask layer, deleting the first mask layer from the content to be captured, and executing the screen capturing or recording function on the content to be captured with the first mask layer deleted; and if the content to be intercepted is determined to comprise the second mask layer, deleting the second mask layer from the content to be intercepted, and executing a screen intercepting or screen recording function on the content to be intercepted of which the second mask layer is deleted. Therefore, when the content screen after screen capture or screen recording is played in the electronic equipment with consistent brightness, the situation that the brightness of the area where the mask layer is located is darker and the brightness of other places is brighter can be avoided.

In one possible design, when the electronic device needs to share display content with the external display, if the content to be shared includes a first mask layer, deleting the first mask layer from the content to be shared, and sharing the content to be shared with the deleted first mask layer with the external display; and if the content to be shared comprises the second mask layer, deleting the second mask layer from the content to be shared, and sharing the content to be shared with the deleted second mask layer to the external display. Therefore, the situation that when the shared content is played by the peripheral display with the consistent screen brightness, the brightness of the area where the mask layer is located is relatively low, and the brightness of other places is relatively high can be avoided.
