Based on the method provided by the embodiment of the application, if the user determines that a display screen has a relatively obvious display boundary when the display screen displays the first picture, the user can adjust the first color component of the first picture and compensate the sub-pixels of the second display area based on the difference value before and after the adjustment of the first color component, so that the requirements of users with different sensitivities and different use habits on the screen consistency are met.

In one possible implementation, the first picture is a pure color picture including one color; or the first picture is a picture with patterns comprising at least two colors. It can be understood that the pure color picture has less visual interference, and can help the user to better judge whether a display boundary exists between different display areas, so that the user can make corresponding adjustment. The picture with the pattern can better reflect the real interface display and can better meet the adjustment requirements of some users with higher perception.

In one possible implementation, the first picture is one of a preset group of pure color pictures with different gray scales; therefore, the user can select the picture which does not meet the screen consistency (has a boundary) from the preset pure color picture, and the screen calibration is carried out according to the picture so as to meet the requirements of users with different sensitivities and different use habits on the screen consistency. Or the first picture is selected from a pure color picture in a preset gray scale range by a user; therefore, the user can check all the pure color pictures in the preset gray scale range, when the screen consistency is checked, the pure color pictures which do not meet the screen consistency (have boundaries) can be selected more flexibly and more accurately, and the screen calibration is carried out according to the pure color pictures, so that the requirements of users with different sensitivities and different use habits on the screen consistency are met. Or the first picture is a first user screenshot; or the first picture is obtained by performing preset processing on the first user screenshot, and when the first user screenshot is displayed in the first display area and the second display area, a display boundary exists at the boundary of the first display area and the second display area.

Illustratively, the first screen may be a primary screen and the second screen may be a secondary screen. That is, the gray scale of the color component of the sub-screen can be adjusted according to the gray scale of the color component of the main screen. The main screen is probably darker due to frequent use, the auxiliary screen is probably brighter due to lower use frequency, and the brightness of the auxiliary screen can be adjusted to be lower so as to keep the brightness of the auxiliary screen consistent with that of the main screen, thereby ensuring the consistency of the screens. And the gray scale of the first color component displayed on the adjusted auxiliary screen is smaller than that of the first color component displayed on the main screen. Alternatively, the first screen may be a secondary screen and the second screen may be a primary screen. The gray scale of the color component of the main screen can be adjusted according to the gray scale of the color component of the auxiliary screen, and the brightness of the main screen can be increased to keep the brightness of the main screen and the brightness of the auxiliary screen consistent, so that the consistency of the screens is ensured.

Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. In the description of the present application, unless otherwise specified, "at least one" means one or more, "a plurality" means two or more. In addition, in order to facilitate clear description of technical solutions of the embodiments of the present application, in the embodiments of the present application, terms such as "first" and "second" are used to distinguish the same items or similar items having substantially the same functions and actions. Those skilled in the art will appreciate that the terms "first," "second," etc. do not denote any order or quantity, nor do the terms "first," "second," etc. denote any order or importance.

The embodiment of the application provides a pixel compensation method, which can be applied to electronic equipment with a display screen, wherein the display screen can comprise a plurality of display areas, and the plurality of display areas can have different display states in different use scenes.

For example, in a multi-window scenario, multiple windows may be displayed on the mobile terminal. For example, as shown in fig. 1A, the plurality of windows displayed on the tablet computer include a video play window 01 and a window 02 for setting an application. The video playing window 01 is displayed in the first display area, and the window 02 for setting the application is displayed in the second display area. Therefore, over time, the first display area and the second display area are attenuated in different degrees (namely, the aging degrees of the different display areas are different) due to different display contents, and when the attenuation difference is increased along with time, a user can perceive the display effect difference between the different display areas, for example, the phenomenon of yin and yang screens appears, the user experience is influenced, and therefore the display effect compensation is required to be carried out on the different display areas, so that the user can not perceive that the display boundaries exist in the different areas of the screen.

For another example, in a video playing scene, as shown in fig. 1B, a video playing window is displayed in a display area 202 (a first display area), and a display area 201 (a second display area) and a display area 203 (a third display area) are in a black screen state, so that different display areas will be attenuated in different degrees due to different lighting time durations of a screen over time, and when the attenuation difference increases with time, a user will perceive a difference in display effect between the different display areas to affect user experience, and therefore, compensation of the display effect for the different display areas is required to be performed, so that the user cannot perceive that a display boundary exists in the different areas of the screen.

In some embodiments, the display screen of the electronic device may be a foldable screen that is foldable to form at least two screens, each of which may correspond to a display area. For example, the foldable screen may include two screens, and the foldable screen may be folded along a folding edge (folding axis) to form a first screen and a second screen, and the first screen may be considered as a first display area and the second screen may be considered as a second display area. The first and second panels may be connected by a first folded edge, which may be considered as the demarcation (demarcation) between the first and second panels. For another example, the foldable screen may include three screens, the foldable screen may be foldable along two foldable edges to form a first screen, a second screen, and a third screen (a third display region), the first screen and the second screen may be connected by a first foldable edge, the second screen and the third screen may be connected by a second foldable edge, and the first foldable edge may be considered as a boundary between the first screen and the second screen, and the second foldable edge may be considered as a boundary between the second screen and the third screen. For another example, the foldable screen may include four screens, five screens, six screens, and so on, which are not described herein.

It should be noted that the folding screen in the embodiment of the present application may be a flexible folding screen. The flexible folding screen comprises a folding edge made of flexible materials. Part or all of the flexible folding screen is made of flexible materials. At least two screens formed by folding the flexible folding screen are a whole screen of an integral structure, and only the flexible folding screen is folded to form at least two parts.

In one possible design, the size of each of the at least two screens included in the folded screen may be the same or different, for example, assuming that the folded screen includes two screens, a first screen and a second screen, respectively, the first screen may be larger than the second screen, or the first screen and the second screen may be the same size.

In one possible design, the at least two screens included in the folding screen may include one or more primary screens and one or more secondary screens. For example, assume that the folding screen includes two screens, one of which (the first screen) may be the main screen and the other (the second screen) may be the sub-screen. When the folding screen is in the folded state, the user may wake up the main screen first by a corresponding operation (e.g., pressing a power key, double-clicking the screen, performing fingerprint recognition), and then may wake up the sub-screen again (e.g., an operation of unfolding the folding screen by the user, or an operation for waking up the sub-screen by the user on the main screen).

The types of the folding screen may include an outward-folded folding screen (hereinafter, an outward-folded folding screen) and an inward-folded folding screen (hereinafter, an inward-folded folding screen). If the folding screen includes two screens, folding screen collapsible formation first screen and second screen promptly, folding screen is folded outward, and first screen and second screen back on the back are carried on the back mutually. The range of the included angle alpha between the first screen and the second screen of the folded-out screen can be [0 degrees, 180 degrees ]. The first screen and the second screen are opposite after the inward folding screen is folded. The range of the included angle alpha between the first screen and the second screen of the folded-in screen can be [0 degrees, 180 degrees ]. The types of the folding screens can also include folding screens which can be turned inwards and can also be turned outwards, namely the range of the included angle alpha between the first screen and the second screen can be [0 degrees, 360 degrees ].

Fig. 2A is a schematic product form diagram of an electronic device 100 with a fold-out folding screen according to an embodiment of the present disclosure. Fig. 2A (a) is a schematic view of the folded-out screen in a fully unfolded state. The outer folded screen may be folded along the first folded edge in the directions 101a and 101B as shown in fig. 2A (a) to form a screen a (i.e., a first screen) and a screen B (i.e., a second screen) as shown in fig. 2A (B). The outer folded screen may be further folded along the first folded edge in the directions 102A and 102b as shown in fig. 2A (b), and may be formed into a folded outer folded screen as shown in fig. 2A (c). As shown in fig. 2A (c), when the foldable screen of the electronic device 100 is completely folded, the a screen and the B screen are opposite to each other and visible to the user.

Under different use scenes, the display area corresponding to the A screen and the display area corresponding to the B screen can have different display states. For example, as shown in (a) of fig. 2A, when the folded screen is in the unfolded state, the a screen and the B screen are simultaneously in the bright screen state. For another example, as shown in (c) of fig. 2A, when the user uses only the a screen in the folded state, the B screen may be in the black screen state.

In one possible design, as shown in fig. 2B, the fold-out folding screen may include a screen a, a screen B, and a fold region, which may be considered to be a screen other than a screen a and a screen B. Fig. 2B (a) is a schematic view of the folded-out screen in a fully unfolded state. The folded-out panels can be folded in the directions 101B and 101B as shown in fig. 2B (a), forming panels a, B and a fold region as shown in fig. 2B (B). The folded-out folding screen can be folded back further in the directions 102a and 102B as shown in fig. 2B (B), and the folded-out folding screen as shown in fig. 2B (c) can be formed. As shown in fig. 2B (c), when the foldable screen of the electronic device 100 is completely folded, the a screen and the B screen are opposite to each other, and the bending region is located in the side region and visible to the user.

Under different use scenes, the display area corresponding to the screen A, the display area corresponding to the screen B and the display area corresponding to the bending area can have different display states. For example, as shown in (a) of fig. 2B, when the folded screen is in the unfolded state, the a screen, the fold area, and the B screen are simultaneously in the bright screen state. For another example, as shown in (c) of fig. 2B, when the user uses only the a-screen in the folded state, the bending region and the B-screen may be in the black screen state. Alternatively, the bending area may be independently lighted, for example, when the foldable screen is in the folded state, if a new incoming call or a new message is received, the bending area may be lighted to prompt the user.

Fig. 2C is a schematic product form diagram of an electronic device 100 with a foldable screen according to an embodiment of the present application. Fig. 2C (a) is a schematic view of the fully unfolded folded-in screen. The inner folded screen may be folded along the first folded edge in the directions 201a and 201B as shown in fig. 2C (a), and may form a screen a (i.e., a first screen) and a screen B (i.e., a second screen) as shown in fig. 2C (B). The fold-in screen may be further folded along the first folded edge in the

directions

When the mobile phone detects that the user clicks an icon 602 of the setting APP on the desktop 601, the setting APP may be started, and a Graphical User Interface (GUI) shown in (a) in fig. 7 is displayed, where the GUI may be referred to as a setting interface 603. The settings interface 603 may display entries for relevant settings for networks and connections, for example, the relevant settings for networks and connections may include entries for mobile networks, WLAN, bluetooth, personal hotspots, and more (network and connection related) settings. The settings interface 603 may also display the relevant settings items for the individual, such as display, sound, wallpaper, and personality theme. Of course, the setting interface 603 may also display other setting items, which is not limited in this application.

As shown in fig. 7 (a), the user may click on the display control 604 on the setting interface 603, and when the mobile phone detects an operation of the user clicking on the display control 604 on the setting interface 603, a GUI as shown in fig. 7 (b) may be displayed, which may be referred to as a display interface 605. The user may click the screen consistency control 606 on the display interface 605, and when the mobile phone detects that the user clicks the screen consistency control 606 on the display interface 605, a GUI as shown in fig. 8 may be displayed, which may be referred to as a screen consistency interface 801.

Alternatively, as shown in fig. 9 (a), the user may click on the more setting control 607 on the setting interface 603, and when the cell phone detects an operation of clicking on the more setting control 607 by the user on the setting interface 603, a GUI as shown in fig. 9 (b) may be displayed, which may be referred to as a more setting interface 608. The user may click on the screen consistency control 609 on the more settings interface 608, and when the cell phone detects that the user has clicked on the screen consistency control 609 on the more settings interface 608, the screen consistency interface 801 as shown in fig. 8 may be displayed. That is, the screen consistency control may be located in different interfaces, and the application is not particularly limited.

As shown in fig. 8, the user may select different ways to adjust the screen consistency of the folded screen at the screen consistency interface 801. The user needs to adjust the screen consistency of the folding screen when the folding screen is in the unfolded state. If the user selects the mode 1, the user can check a group of preset pure color pictures with different gray scales provided by the system. When each pure color picture is displayed, if a display boundary exists at the boundary of the first screen and the second screen (for a user, the pure color picture can be considered to have the display boundary), the user can adjust the pure color picture, and the more the number of the adjusted pictures is, the better the screen consistency adjusting effect is; if the user selects the mode 2, the user can check the pure color picture in the preset gray scale range, when the pure color picture with a certain gray scale value is displayed, if a display boundary exists at the boundary of the first screen and the second screen, the user can adjust the screen consistency of the pure color picture, and the more the number of the adjusted pictures is, the better the screen consistency adjusting effect is; if the user selects the mode 3, the user can select one or more screenshot pictures with a display boundary during display, and screen consistency adjustment is performed according to the screenshot pictures. As shown in fig. 8, if the user selects the mode 3, the user may select one or more screenshot pictures in the system album by selecting the picture control 803, where the one or more screenshot pictures are obtained by screenshot when the user finds that a display boundary exists at a boundary between the first screen and the second screen of the mobile phone during the use process. Or, the user can directly jump to the corresponding application program and enter the corresponding interface (the user finds that the interface of the display boundary exists at the boundary between the first screen and the second screen of the mobile phone in the using process) to perform screenshot through the screenshot removing control 804, or jump to the desktop to perform screenshot, and after the screenshot is finished, the user can quickly return to the relevant interface of the screen calibration through the corresponding control.

After the user selects the screen consistency adjusting mode, the mobile phone can display a first interface on the first screen and the second screen, and the first interface comprises a first picture. It should be understood that the first picture may include a plurality of pixels, and each pixel may be composed of three Red Green Blue (RGB) sub-pixels. The three sub-pixels red (R), green (G) and blue (B) may each have 256 levels of gray scale/gray scale (from 0 to 255), with the gray scale/gray scale of the sub-pixel representing the gradation level of the sub-pixel from the darkest to the brightest with different brightness. The red, green and blue sub-pixels of different brightness levels are combined to finally form pixels of different colors. If the gray scale of each sub-pixel of each pixel is 255, that is, all sub-pixels are turned on to the maximum brightness, the screen is white, and it can be considered that a white picture is displayed on the screen, and the gray scale of the white picture is 255. The gray scales of the sub-pixels of all the pixels are reduced uniformly, the screen can display gray with different gray scales/gray scales, and the screen can be considered to display pictures with different gray scales. Different sub-pixels correspond to different color components, for example, the R sub-pixel corresponds to a red component, the gray scale of the R sub-pixel is the gray scale of the red component, the G sub-pixel corresponds to a green component, the gray scale of the G sub-pixel is the gray scale of the green component, the B sub-pixel corresponds to a blue component, and the gray scale of the B sub-pixel is the gray scale of the blue component.

The first picture is a pure-color picture comprising one color; or the first picture is a picture with patterns comprising at least two colors. The gray-scale values of all pixels included in the pure-color picture are the same, and the gray-scale values of the sub-pixels of each pixel are the same or different. For example, assuming a pure color picture includes 100 pixels, the R, G, B sub-pixels of each of the 100 pixels may have a gray scale value of 100, 100, 100; alternatively, the R, G, B sub-pixels for each of the 100 pixels may have a grayscale value of 50, 100, 150. The gray-scale values of all pixels included in the picture with the pattern are not completely the same, and the gray-scale values of the sub-pixels of each pixel are the same or different.

If the user selects the method 1, the first picture may be one of a set of preset pure color pictures with different gray scales. For example, 3 solid color pictures may be preset, the preset solid color pictures may be selected from a full gray scale range (e.g., 0-255), such as the preset 3 solid color pictures may be 60, 180, and 255, respectively, or the preset solid color pictures may be selected from a low gray scale range (e.g., 0-100), such as the preset 3 solid color pictures may be 30, 70, and 100. The preset R component (red component), G component (green component), and B component (blue component) of each pure color picture may have the same gray scale value, for example, the gray scale values of R, G, B components of a pure color picture with a gray scale value of 60 are all 60, and a pure color picture with R, G, B components having the same gray scale value may also be referred to as a gray scale picture.

For example, as shown in fig. 8, if the user selects the method 1, that is, the user clicks the control 802 on the screen consistency interface 801, after the mobile phone detects that the user clicks the control 802 on the screen consistency interface 801, the interface 1001 shown in fig. 10A may be displayed, where the interface 1001 is the first interface. The interface 1001 includes a first picture, which may be, for example, a solid color picture with a gray scale value of 60(R, G, B components having a gray scale value of 60). The first picture may fill (flood) the first screen and the second screen. On the first picture, some user prompt information and function buttons may be displayed. For example, a prompt message 1002, an OK button 1003, a calibration button 1004, and a dotted line 1005 and a dotted line 1006 may be displayed. An area between the dotted line 1005 and the dotted line 1006 may be referred to as a dotted line area 1007 (a folding area, i.e., an area where a boundary of the first screen and the second screen is located), and a user may view within the dotted line area 1007 to determine whether there is a faint boundary within the dotted line area 1007. The boundary may be due to a difference in decay rates of the first and second screens. The screen with the fast attenuation speed may be darker (or yellow), and the screen with the slow attenuation speed may be brighter, so that the situation of yin and yang screens may occur, and a light boundary may exist in the dotted line area 1007, which affects the user experience. If the user determines that a boundary exists in the dashed area 1007, the user can click the calibration button 1004 to calibrate the screen; if the user determines that there is no obvious boundary in the dashed area 1007, the user may click the OK button to enter a next step, for example, may enter a second interface, where the second interface includes a second picture, and the second picture is different from the first picture, and the user may check whether there is a boundary between the first screen and the second screen when displaying the second picture.

If the user selects the method 2, the first picture may be selected from the pure color picture within the preset gray scale range by the user. The gray scale values of the R component, the G component and the B component of each pure color picture in the preset gray scale range can be the same or different. Taking the gray values of the R component, the G component, and the B component of the pure color picture as an example, as shown in fig. 10B, a slider 1008 may be provided on the first interface 1001, and the user may select a pure color picture by dragging the slider 1009 on the slider 1008. The gray scale range corresponding to the sliding bar can be 0-255, and a user can check whether the pure color pictures of each gray scale meet the screen consistency (whether a boundary exists) and select one pure color picture with the boundary from the pure color pictures with the gray scale values of 0-255 (namely, when the pure color picture is displayed, a display boundary exists at the boundary of the first screen and the second screen). Or, a numerical value selection box can be provided on the first interface, the corresponding gray scale range of the data selection box can be 0-255, and a user can select a pure color picture with a boundary by modifying the numerical value of the data selection box. Therefore, a user can check all the pure color pictures in the preset gray scale range, when the screen consistency is checked, the pure color pictures which do not meet the screen consistency (have boundaries) can be selected more flexibly and more accurately, and the screen calibration is carried out according to the pure color pictures.

If the user selects the mode 3, the first picture may be the first user screenshot or obtained by performing preset processing on the first user screenshot. For example, a user may select a user screenshot with a display boundary from the system album (that is, when the user screenshot is displayed, a display boundary exists at a boundary between the first screen and the second screen), the mobile phone may use the user screenshot selected by the user (the first user screenshot) as the first picture, or the mobile phone may perform preset processing on the user screenshot selected by the user (the first user screenshot) to obtain the first picture. The preset processing may be graying processing of the first user screenshot, and the R component, the G component, and the B component of each pixel of the first picture obtained after the graying processing are respectively the same as the average values of the R component, the G component, and the B component of the first user screenshot. Wherein the average value of the R components of the first user screenshot is a quotient of the sum of the grayscale values (R components) of all R subpixels included in the first user screenshot and the number of all R subpixels included in the first user screenshot. Similarly, the average value of the G components of the first user screenshot is the quotient of the sum of the gray-scale values (G components) of all the G subpixels included in the first user screenshot and the number of all the G subpixels included in the first user screenshot, and the average value of the B components of the first user screenshot is the quotient of the sum of the gray-scale values (B components) of all the R subpixels included in the first user screenshot and the number of all the B subpixels included in the first user screenshot. Therefore, the user can carry out screen calibration according to the first user screenshot or the first picture corresponding to the first user screenshot in a more targeted manner.

In addition, in some embodiments, after the mobile phone detects the operation of the user clicking the screen consistency control 606 on the display interface 605, or after the mobile phone detects the operation of the user clicking the screen consistency control 609 on the more setting interfaces 608, as shown in fig. 10A, the mobile phone may directly display the first interface 1001, and the first picture in the first interface 1001 may be one of a preset set of solid-color pictures with different gray scales. Alternatively, as shown in fig. 10B, the user may drag the slider bar on the first interface to select a solid color picture. Alternatively, after the mobile phone detects the user's operation of clicking the screen consistency control 606 on the display interface 605, or after the mobile phone detects the user's operation of clicking the screen consistency control 609 on the more setting interface 608, a prompt box may pop up to prompt the user to select one or more screenshots with display boundaries from the system album for screen consistency calibration.

502. And receiving a first operation of a user, wherein the first operation is used for determining screen calibration according to the first picture.

When the first screen and the second screen display the first picture, if the user determines that a display boundary exists at the boundary of the first screen and the second screen, the user can perform a first operation on the first interface and determine to perform screen calibration. For example, as shown in fig. 10A, if the user determines that a boundary exists in the folding area 1007, the user may click the calibration button 1004, and the mobile phone receives a click operation of the user on the calibration button 1004 displayed on the folding screen, and determines that the user needs to perform screen calibration according to the first picture.

Or, the user may input a voice operation instruction, where the voice operation instruction is used to indicate that screen calibration is required, and the mobile phone may receive the voice operation instruction of the user and determine that the screen calibration is required by the user. For example, a user may speak "calibrate" or "i want to calibrate" near the microphone, and the handset receives voice information entered by the user and determines that the user needs to perform a screen calibration.

503. In response to the first operation, a first color component of the first picture is displayed on the first screen and the second screen.

After the mobile phone determines that screen calibration needs to be performed according to the first picture, the first picture can be decomposed into at least one color component, and each color component in the at least one color component is respectively displayed on the first screen and the second screen, so that a user can calibrate each color component respectively. Of course, if the first picture is a pure color picture with only one color component, no further decomposition is needed. For example, the gray scale of R, G components of each pixel of the first picture may be 100, 0, 0, i.e. the first picture is a pure red picture, and then the first picture does not need to be decomposed.

In some embodiments, the cell phone may decompose the first picture into one or more of a red component, a green component, a blue component, a yellow component, a cyan component, or a magenta component. For example, the handset may decompose a first picture into a red component, a green component, and a blue component; alternatively, the handset may decompose the first picture into a blue component and a yellow component, the yellow component being a mixture of the red and green components.

The mobile phone may display each of the color components according to a preset sequence, for example, if the mobile phone decomposes the first picture into a red component, a green component, and a blue component, the mobile phone may display each color component according to the sequence of the red component, the green component, and the blue component, that is, the first color component is the red component; or, the mobile phone may display each color component according to the order of the blue component, the green component, and the red component, that is, the first color component is the blue component, which is not limited in this application.

For example, assuming that the mobile phone can decompose the first picture into a red component, a green component, and a blue component, and display the color components according to the order of the red component, the green component, and the blue component, as shown in fig. 10A, in response to an operation of the user clicking on the calibration button 1004, as shown in (a) in fig. 11, the mobile phone can display the red component on the interface 1101, and on the interface 1101, some user prompt information and function buttons, such as a slider 1102, a save button 1103, prompt information 1104, and a dotted line area 1105, can also be displayed. The user can observe in the dashed-line area 1105, determine whether a light boundary exists in the dashed-line area 1105, if the boundary exists, the slider 1102 can be dragged to perform adjustment, and after the adjustment is completed, the user can click the save button 1103 to save the adjustment information and can continue to adjust the next color component. When the mobile phone detects an operation of clicking the save button 1103 by the user on the interface 1101, an interface 1106 as shown in (b) in fig. 11 may be displayed, the mobile phone may display a green component on the interface 1106, and may further display some user prompt information and function buttons on the interface 1106, for example, a slider 1107, a save button 1109, prompt information 1111, and a dotted line area 1110. The user can observe the dotted area 1110 to determine whether a light boundary exists in the dotted area 1110, if so, the slider 1107 can be dragged to perform adjustment, and after the adjustment is completed, the save button 1109 can be clicked to save the adjustment information and continue to adjust the next color component. When the mobile phone detects that the user clicks the save button 1109 on the interface 1106, an interface 1112 as shown in (c) of fig. 11 may be displayed, the mobile phone may display a blue component on the interface 1112, and may also display some user prompt information and function buttons on the interface 1102, for example, a slider 1113, a save button 1114, prompt information 1116 and a dotted line area 1115. The user can view the dashed area 1115 to determine whether there is a weak boundary within the dashed area 1115, and if so, drag the slider 1107 for adjustment.

504. And receiving a second operation of the user, wherein the second operation is used for adjusting the gray scale of the first color component displayed on the second screen according to the gray scale of the first color component displayed on the first screen, and the gray scale of the first color component displayed on the first screen is unchanged.

Illustratively, the first screen may be a primary screen and the second screen may be a secondary screen. That is, the gray scale of the color component of the sub-screen can be adjusted according to the gray scale of the color component of the main screen. The main screen is probably darker due to frequent use, the auxiliary screen is probably brighter due to lower use frequency, and the brightness of the auxiliary screen can be adjusted to be lower so as to keep the brightness of the auxiliary screen consistent with that of the main screen, thereby ensuring the consistency of the screens. And the gray scale of the first color component displayed on the adjusted auxiliary screen is smaller than that of the first color component displayed on the main screen. Alternatively, the first screen may be a secondary screen and the second screen may be a primary screen. The gray scale of the color component of the main screen can be adjusted according to the gray scale of the color component of the auxiliary screen, and the brightness of the main screen can be increased to keep the brightness of the main screen and the brightness of the auxiliary screen consistent, so that the consistency of the screens is ensured. And the gray scale of the first color component displayed on the adjusted main screen is larger than that of the first color component displayed on the auxiliary screen.

For example, as shown in fig. 11 (a), the user may adjust the gray level of the first color component (red color component) displayed on the second screen by dragging the slider 1102. In the adjustment process, the gray scale of the first color component displayed on the first screen is not changed, and the gray scale of the first color component displayed on the second screen is changed according to the change of the position of the slider 1102. Alternatively, the user may adjust the gray scale of the first color component displayed on the second screen by modifying the numerical value of the numerical value selection box for adjusting the gray scale displayed on the second screen.

505. And responding to the second operation, and displaying the adjustment effect of the gray scale of the first color component on the second screen in real time.

As shown in fig. 11 (a), the user may drag the slider 1102, the position of the slider 1102 is changed, and the gray scale of the first color component displayed on the second screen is changed according to the change of the position of the slider 1102.

506. And receiving a third operation of the user, wherein the third operation is used for determining that the current adjusting effect meets the screen consistency.

As shown in (a) and (b) of fig. 12A, in the interface 1101, after the user drags the slider 1102 from the first position to the second position, if it is determined that the faint boundary in the dashed-line area 1105 disappears, that is, the slider is located at the second position, the faint boundary does not exist in the dashed-line area 1105, that is, the screen consistency is satisfied, and the user may click the save button to save the current adjustment result.

After the mobile phone determines that the user finishes adjusting the first color component, the second color component can be displayed on the first screen and the second screen; the second color component is different from the first color component. For example, as shown in (a) in fig. 11, when the cellular phone detects an operation of the user clicking the save button 1103 on the interface 1101, an interface 1106 as shown in (b) in fig. 11 may be displayed, and the cellular phone may display a green component on the interface 1106.

Further, the mobile phone may receive a fifth operation of the user, where the fifth operation is used to adjust the gray scale of the second color component displayed on the second screen according to the gray scale of the second color component displayed on the first screen, and the process of the user adjusting the gray scale of the second color component displayed on the second screen may refer to the process of the user adjusting the gray scale of the first color component displayed on the second screen, which is not described herein again.

After the mobile phone determines that the user finishes adjusting the second color component, the third color component can be displayed on the first screen and the second screen; the third color component is different from the first color component and the second color component. For example, as shown in (b) in fig. 11, when the cellular phone detects an operation of the user clicking the save button 1109 on the interface 1106, an interface 1111 as shown in (c) in fig. 11 may be displayed, and the cellular phone may display a blue component on the interface 1112. Further, the mobile phone may receive an operation for the user to adjust the gray scale of the blue component displayed on the second screen.

It should be noted that, the user does not adjust the gray scale of each color component on the interface corresponding to each color component, and only when the user thinks that there is a boundary line on the interface corresponding to the color component, the user adjusts the gray scale of the color component, and if the user thinks that there is no boundary line on the interface corresponding to the color component, the user can directly click the save button to enter the next step (i.e., enter the adjustment interface of the next color component).

It can be understood that there may be a large error in performing the screen calibration according to only one picture, so that the user can adjust multiple pictures to improve the accuracy of the screen consistency calibration. For example, after the user has adjusted each color component of the first picture, the mobile phone may further display a second interface on the first screen and the second screen, where the second interface includes a second picture that is different from the first picture.

The second picture may be one of a set of predetermined solid color pictures with different gray scales, for example, the second picture may be a solid color picture with a gray scale value of 180, or the second picture is obtained by adding or subtracting a predetermined gray scale value to or from the first picture, for example, if the gray scale value of the second picture is 30 times the gray scale value of the first picture, if the gray scale value of the first picture is 60, the gray scale value of the second picture may be 60+ 30-90. Or the second picture may be obtained by performing preset processing on a second user screenshot, where the second user screenshot is different from the first user screenshot. Or, the second picture is selected from the pure color pictures in the preset grayscale range by the user, for example, after the user has adjusted each color component of the first picture, the interface shown in fig. 10B may be returned, and the user may drag the slider 1009 on the slider 1008 to reselect a pure color picture (i.e., the second picture) with a boundary.

Further, the mobile phone may receive a sixth operation of the user, where the sixth operation is used to determine to perform screen calibration according to the second picture, and in response to the sixth operation, the mobile phone may display the first color component of the second picture on the first screen and the second screen; then, the mobile phone may receive a seventh operation of the user, where the seventh operation is used to adjust the gray scale of the first color component displayed on the second screen according to the gray scale of the first color component displayed on the first screen. The process of adjusting each color component of the second picture by the user may refer to the process of adjusting each color component of the first picture by the user, which is not described herein again.

Finally, after the user finishes adjusting each color component of each pure color picture, the user waits for the screen calibration to take effect, and the screen calibration taking effect process may be as described in step 507:

507. and determining a compensation value of a first sub-pixel on the second screen according to a first difference value between the gray scale of the first color component displayed on the second screen after adjustment and the gray scale of the first color component displayed on the second screen before adjustment, wherein the first sub-pixel is a sub-pixel corresponding to the first color component, and compensating the first sub-pixel on the second screen according to the compensation value of the first sub-pixel on the second screen.

If the user only adjusts the first color component of a pure color picture (e.g., the first picture), the mobile phone may determine the compensation value of the first sub-pixel on the second screen according to a first difference between the adjusted gray scale of the first color component displayed on the second screen and the gray scale before the adjustment. As shown in (a) and (b) of fig. 12A, the first difference value may be a difference value (e.g., a gain value) between a gray level of the first color component when the slider 1102 is at the first position and a gray level of the first color component when the slider 1102 is at the second position.

For example, the mobile phone may determine a gain (gain) value (e.g., the gain value may be 8/100 ═ 0.08) of the first sub-pixel on the second screen according to a first difference value (e.g., assuming that the gray scale of the first sub-pixel on the second screen before the adjustment is 100 and the gray scale after the adjustment is 92, and the first difference value is 100-92 ═ 8), simulate a gamma adjustment curve for the first sub-pixel on the second screen according to the gain value, and determine a compensation value of the first sub-pixel on the second screen at all gray scales (e.g., 0-255) according to the gamma adjustment curve of the first sub-pixel.

Similarly, the mobile phone may determine a gain value of a second sub-pixel on the second screen according to a difference value before and after adjustment of a second color component of the first picture, simulate a gamma adjustment curve for the second sub-pixel on the second screen according to the gain value, and then determine a compensation value of the second sub-pixel on the second screen at all gray levels according to the gamma adjustment curve of the second sub-pixel, where the second color component corresponds to the second sub-pixel. The mobile phone can determine a gain value of a third sub-pixel on the second screen according to a difference value before and after adjustment of a third color component of the first picture, simulate a gamma adjustment curve for the third sub-pixel on the second screen according to the gain value, and further determine a compensation value of the third sub-pixel on the second screen in all gray scales according to the gamma adjustment curve of the third sub-pixel, wherein the second color component corresponds to the third sub-pixel. Then, the mobile phone can compensate each sub-pixel on the second screen according to the compensation value of each sub-pixel on the second screen.

If the user adjusts a plurality of pure color pictures, for example, two pictures, which are respectively a first picture and a second picture, the compensation value of the first sub-pixel on the second screen may be determined according to a first difference value between the gray scale of the first color component after the adjustment of the first picture and the gray scale of the first color component before the adjustment, and a second difference value between the gray scale of the first color component after the adjustment of the second picture and the gray scale of the first color component before the adjustment.

For example, the mobile phone may determine a gain value of the first sub-pixel on the second screen according to the first difference value and the second difference value, simulate a gamma adjustment curve for the first sub-pixel according to the gain value, and then determine a compensation value of the first sub-pixel on the second screen at all gray levels according to the gamma adjustment curve of the first sub-pixel. The compensation value of the first sub-pixel on the second screen determined from the first difference and the second difference is more accurate than the compensation value of the first sub-pixel on the second screen determined from only the first difference.

Similarly, the mobile phone may determine a gain value of a second sub-pixel on the second screen according to a difference value before and after adjustment of the second color component of the first picture and a difference value before and after adjustment of the second color component of the second picture, simulate a gamma adjustment curve for the second sub-pixel according to the gain value, and then determine a compensation value of the second sub-pixel on the second screen at all gray levels according to the gamma adjustment curve of the second sub-pixel. The mobile phone can determine a gain value of a third sub-pixel on the second screen according to a difference value before and after adjustment of the third color component of the first picture and a difference value before and after adjustment of the third color component of the second picture, simulate a gamma adjustment curve for the third sub-pixel according to the gain value, and further determine a compensation value of the third sub-pixel on the second screen in all gray scales according to the gamma adjustment curve of the third sub-pixel. Then, the mobile phone can compensate each sub-pixel on the second screen according to the compensation value of each sub-pixel on the second screen.

Optionally, before step 504, a step 503a may be further included:

503a, receiving a fourth operation of the user, wherein the fourth operation is used for adjusting the backlight brightness of the folding screen.

Since the OLED screen emits light in a single pixel, the aging phenomenon of the OLED screen can give different degrees of screen consistency difference feeling to users under different backlight brightness/intensity. Therefore, each picture under each backlight brightness can be checked by adjusting the backlight brightness, and pictures which do not meet the screen consistency are adjusted to meet the requirement of a user on the screen consistency.

For example, as shown in (a) or (B) of fig. 12B, a slider 1010 may be further provided on the interface 1001, and the user may select the corresponding backlight brightness by dragging the slider 1011 on the slider 1010. The corresponding luminance range for slider 1010 may be 0-255. Alternatively, a value selection box may be provided on the first interface, for example, the data selection box may correspond to a brightness range of 0-255, and the user may select the corresponding backlight brightness by modifying the value of the data selection box.

Optionally, a color space selection picture can be provided for the user, and the user customizes the gray scale and the color component which need to be adjusted, so as to provide better screen display experience.

Fig. 17 is a block diagram of a software configuration of an electronic device according to an embodiment of the present application. The software system of the electronic device may employ a layered architecture, an event-driven architecture, a micro-core architecture, a micro-service architecture, or a cloud architecture. The embodiment of the invention takes an Android system with a layered architecture as an example, and exemplarily illustrates a software structure of an electronic device.

The layered architecture divides the software into several layers, each layer having a clear role and division of labor. And the layers communicate with each other through an interface. In some embodiments, the Android system is divided into four layers, which are an application layer, an application framework layer, an Android runtime and system library, and a kernel layer from top to bottom.

The application layer may include a series of application packages.

As shown in fig. 17, the application package may include applications such as camera, gallery, calendar, phone call, map, settings, WLAN, bluetooth, music, video, short message, etc.

The application framework layer provides an Application Programming Interface (API) and a programming framework for the application program of the application layer. The application framework layer includes a number of predefined functions.

As shown in fig. 17, the application framework layer may include an activity manager, a window manager, a content provider, a resource manager, a notification manager, and the like, which is not limited in this embodiment.

Activity Manager (Activity Manager): for managing the lifecycle of each application. Applications typically run in the operating system in the form of Activity. For each Activity, there is an application record (activetyrecord) in the Activity manager corresponding to it, which records the state of the Activity of the application. The Activity manager can schedule Activity processes for the application using this Activity record as an identification.

Window manager (windowmanager service): graphical User Interface (GUI) resources for managing GUI resources used on a screen may specifically be used to: the method comprises the steps of obtaining the size of a display screen, creating and destroying a window, displaying and hiding the window, arranging the window, managing a focus, managing an input method, managing wallpaper and the like.

In the embodiment of the application, the application framework layer may further include a screen consistency adjustment service, and the screen consistency adjustment service may present different display effects on the display screen according to user operations.

For example, as shown in fig. 8, after the user selects the screen consistency adjustment mode, the mobile phone performs screen calibration initialization, adjusts the gamma unit and/or the demura unit to an initial state, and optionally switches the screen backlight to a manual mode. In the first picture adjustment scene shown in fig. 10A, after detecting that the user instructs to calibrate the first picture (i.e., the operation of clicking the calibration button 1004), the electronic device displays an adjustment interface for the first color component as shown in (a) of fig. 11. After the touch sensor detects the operation of dragging the slider 1102 by the user, the screen consistency adjustment service may call a gamma adjustment unit in the AP drive or may call a demura unit in the DDIC drive to compensate for each sub-pixel on the second screen. If the user confirms that the screen consistency reaches the standard, the user can click the storage button, after the touch sensor detects that the user clicks the storage button, the screen consistency adjusting service can write the adjusting result into the display terminal chip and store the adjusting result into the file system, and the requirement of the user can be met by using subsequent products.
