[0031] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " represents the meaning of or, for example, A / B can represent A or B; the "and / or" in the text only describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which means that there are three cases of A alone, A and B together, and B alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0032] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined with "first" and "second" can explicitly or implicitly include one or more of the features, and in the description of the embodiments of the present application, unless otherwise specified, the meaning of "multiple" is two or more than two.

[0033] The term "user interface (UI)" in the following embodiments of the present application is a medium interface for interaction and information exchange between an application or an operating system and a user, which realizes the conversion between the internal form of information and the form that the user can accept. The user interface is source code written in a specific computer language such as Java, extensible markup language (XML), etc. The interface source code is parsed, rendered, and finally presented as content that can be recognized by the user on the electronic device. The commonly used form of user interface is graphic user interface (GUI), which refers to a user interface related to computer operation displayed in a graphical manner. It can be a visual interface element such as text, icon, button, menu, tab, text box, dialog box, status bar, navigation bar, Widget, etc. displayed in the display screen of the electronic device.

[0034] In order to facilitate understanding of the schemes provided by the embodiments of the present application, the related concepts related to the embodiments of the present application are introduced as follows:

[0035] The lock screen can mean locking the screen of the electronic device to prevent accidental touch, accidental touch or use of the user's electronic device by others. The user cannot use the electronic device in the lock screen state. The user can only use the electronic device after the electronic device is unlocked by the user set unlocking method.

[0036] The lock screen off state can refer to a state in which the electronic device switches to a lock screen and the screen is turned off in response to a lock screen operation. The lock screen operation can include, but is not limited to, a pressing operation of a lock screen key acting on a side or top edge of the electronic device, a click operation acting on a lock screen control in a user interface, a voice instruction, a gesture instruction, and the like.

[0037] The lock screen on state can refer to a state in which the electronic device switches to a lock screen and the screen is turned on in response to an on screen operation while the electronic device is in the lock screen off state. The on screen operation can include, but is not limited to, a double-click operation of the screen, a lifting operation of the electronic device, and the like. In some implementations, the electronic device can set a time length in the lock screen on state in response to a user operation. Specifically, the electronic device switches to the lock screen on state in response to the on screen operation and lasts for a certain time (for example, 10s). Then the electronic device switches to the lock screen off state.

[0038] The unlock on state can refer to a state in which the electronic device switches to an unlocked state and the screen is turned on in response to an unlock operation while the electronic device is in the lock screen off state or the lock screen on state. The unlock operation can include, but is not limited to, a touch operation acting on a specific area (for example, a fingerprint recognition area), a face unlock operation facing the camera, an operation of inputting a password (for example, an alphabetical and / or numerical password, a pattern password), and the like. In one possible implementation, the first two operations can be implemented when the electronic device is in the lock screen off state or the lock screen on state, and the last operation can be implemented only when the electronic device is in the lock screen on state.

[0039] The wallpaper can refer to a picture displayed in the entire screen of the electronic device. The wallpaper can include a lock screen wallpaper and a desktop wallpaper. The wallpaper can include a picture pre-installed in the electronic device, and can also include a picture stored in the photo album of the electronic device. The lock screen wallpaper can be displayed when the electronic device is in the lock screen on state, and the desktop wallpaper can be displayed when the electronic device is in the unlock on state.

[0040] The structure of the electronic device provided in the embodiments of the present application will be introduced first.

[0041] The electronic device provided in the embodiments of the present application is an electronic device with an outer folding screen. The outer folding screen can refer to a screen that can be observed by the user after folding, i.e., the screen is outward after folding. Unlike the inner folding screen, the screen cannot be observed by the user after folding, i.e., the screen is hidden inward after folding. The main screen and the side area are connected by a first folding component, and the back screen and the side area are connected by a second folding component.

[0042] Figure 1A The structure of the electronic device in the unfolded state is exemplarily shown.

[0043] AsFigure 1A As shown, the electronic device can include but is not limited to: back screen 201, main screen 202, side area 203. The back screen 201, the main screen 202, and the side area 203 can be referred to as a whole screen. In the case that the electronic device is in the unfolded state, the included angle between the back screen 201 and the main screen 202 is 180 degrees or approximately 180 degrees. The orientation of the whole screen of the electronic device is consistent with the orientation of the back screen 201 and the main screen 202, that is Figure 1A As shown, the orientation of the main screen is consistent with the orientation of the back screen. Further, the orientation of the main screen, the orientation of the side area, and the orientation of the back screen are all consistent.

[0044] When the user faces the whole screen, the display area that the user can observe is the whole screen. In one possible implementation, the back of the face where the whole screen of the electronic device is located does not contain a display screen. In another possible implementation, the back of the face where the whole screen of the electronic device is located contains a display screen. In the embodiments of the present application, the back of the face where the whole screen of the electronic device is located does not contain a display screen is taken as an example for description.

[0045] Figure 1B An exemplary structure of the electronic device in the folded state is shown.

[0046] As shown, Figure 1B As shown, (a) and (b) are structure of the electronic device in the folded state observed from different directions. Wherein, (a) is a structure of the electronic device observed from the front, (b) is a structure of the electronic device observed from the back. In the embodiments of the present application, the above front and back are only exemplary described, only used to represent that the observation angle of the two is 180 degrees, and this is not limited.

[0047] The electronic device can include but is not limited to: back screen 211, main screen 212, side area 213. In the case that the electronic device is in the folded state, the included angle between the back screen 201 and the main screen 202 is 0 degrees or approximately 0 degrees. Optionally, the electronic device can also include: back screen camera 214. The orientation of the back screen camera 214 will not change with the folding or unfolding of the electronic device.

[0048] In (a), the orientation of the back screen and the orientation of the main screen are as shown in (a). The user faces the back screen 211 and can observe the back screen 211, but cannot observe the main screen. In (b), the orientation of the back screen and the orientation of the main screen are as shown in (b). The user faces the main screen 212 and can observe the main screen 212, but cannot observe the back screen. That is, when the electronic device is in the folded state, the orientation of the main screen is opposite to the orientation of the back screen, and the orientation of the side area is 90 degrees or approximately 90 degrees to the orientation of the main screen, and the orientation of the side area is also 90 degrees or approximately 90 degrees to the orientation of the back screen.

[0049] In the embodiments of the present application,Figure 1A With Figure 1B The structural form of the electronic device shown is only illustrative, and the electronic device can also include more or fewer structures, which is not limited.

[0050] In some implementations, when the electronic device is in the unfolded state, the entire screen can simultaneously display wallpaper, such as a lock screen wallpaper, a desktop wallpaper.

[0051] In some implementations, when the electronic device is in the folded state, the following cases exist: 1, the entire screen simultaneously displays wallpaper. 2, the back screen displays content, and the main screen and the side area do not display content. 3, the main screen displays content, and the back screen and the side area do not display content. How the electronic device displays content in the folded state can be referred to the related content of the following method flow, which will not be described here.

[0052] The display ranges of the main screen, the back screen, and the side area in the electronic device are introduced below.

[0053] Figure 2 An example of the division of the outer folding screen in the electronic device is shown.

[0054] As shown in Figure 2 , the total width of the outer folding screen is w, and the height is h. Taking point A1 as the coordinate origin, the wide side of the outer folding screen as the X axis, and the high side as the Y axis. The width of the back screen is w1, and the height is h. The four vertices of the back screen are A1, B1, C1, and D1. Among them, the coordinates of A1 are (0, 0), the coordinates of B1 are (w1, 0), the coordinates of C1 are (0, h), and the coordinates of D1 are (w1, h). The four vertices of the main screen are A2, B2, C2, and D2. Among them, the coordinates of A2 are (w-w2, 0), the coordinates of B2 are (w, 0), the coordinates of C2 are (w-w2, h), and the coordinates of D2 are (w, h). The display range of the back screen is [(0, 0)–(w1, h)], the display range of the side area is [(w1, 0)–(w-w2, h)], and the display range of the main screen is [(w-w2, 0)–(w, h)]. When the electronic device is in the unfolded state, all the above-mentioned areas can display content. When the electronic device is in the folded state, the main screen and the back screen switch the display content, and the size of the displayed content needs to be adjusted according to the size ratio of the main screen and the back screen. How to adjust can be referred to the related description in the following method flow, which will not be described here.

[0055] In one possible implementation, the length of the back screen of the electronic device is consistent with the length of the main screen, and the width of the back screen is smaller than the width of the main screen. For example, the width of the back screen is 85% of the width of the main screen. In the embodiments of the present application, the above-mentioned value 85% is only illustrative, and only the width of the main screen is greater than the width of the back screen, which is not limited.

[0056] The related application scenarios involved in the embodiments of the present application are introduced below.

[0057] Scenario one: the electronic device sets lock screen wallpaper for the back screen and sets lock screen text for the side area.

[0058] Figures 3A-3H A related user interface for setting lock screen wallpaper for the back screen and text for the side area in the embodiments of the present application is shown.

[0059] As shown in Figure 3A , the user interface 300 is a user interface provided by the settings application of the electronic device. The electronic device can display the user interface 300 in response to a setting icon in the desktop. The user interface 300 can include a plurality of function bars, such as a folding screen special area bar 301. The electronic device can display the user interface 310 in response to a click operation acting on the folding screen special area bar 301.

[0060] As shown in Figure 3B , the user interface 310 is a user interface used by the electronic device to set functions related to the folding screen. The user interface 310 can include but is not limited to: an application display ratio control 311, an application split screen control 312, a personalized back screen and side display control 313. The electronic device can display the user interface 320 in response to a click operation acting on the personalized back screen and side display control 313.

[0061] As shown in Figure 3C , the user interface 320 is a user interface provided by the electronic device to start or stop the personalized back screen and side display function. The user interface 320 can include but is not limited to: a back screen preview area 321, a side preview area 322, a style replacement control 323, a sliding control 324. The back screen preview area 321 can be used to display the lock screen wallpaper set by the electronic device for the back screen. The side preview area 322 can be used to display the lock screen text set by the electronic device for the side area. The electronic device can start or stop the personalized back screen and side display function in response to a click operation acting on the sliding control 324. Starting the personalized back screen and side display function can mean that the electronic device displays the lock screen wallpaper set for the back screen and the lock screen text set for the side area. In a possible implementation manner, the electronic device can start the personalized back screen function and stop the side display function; or the electronic device can start the side display function and stop the personalized back screen function. The electronic device can display the user interface 330 in response to a click operation acting on the style replacement control 323.

[0062] As shown in Figure 3DAs shown, the user interface 330 is a user interface provided by the electronic device for a series of settings for the lock screen wallpaper displayed on the back screen and the lock screen text displayed on the side area. The user interface 330 can include, but is not limited to, a back screen preview area 331, a side preview area 332, a select picture control 333, a back screen wallpaper bar 334, a back screen signature type bar 335, a back screen signature input box 336, a back screen signature color bar 337, an alignment mode bar 338, a font size sliding control 339, a font thickness sliding control 341, a side text type bar 342, a side text input box 343, a side text color bar 344, a restore control 345, an application control 346, and the like. In the embodiments of the present application, the content included in the user interface 330 includes the content after the electronic device responds to the up swipe operation in the user interface 300, and the content included in the user interface 330 is not limited.

[0063] As can be seen from the back screen preview area 331 and the side preview area 332 in the user interface 330, before the present setting, the electronic device has not set the lock screen wallpaper for the back screen, and therefore, the "+" is displayed in the back screen preview area 331 and no lock screen wallpaper is displayed. In addition, since the electronic device has not set the lock screen wallpaper for the back screen, the select picture control 333 displays the text content "select picture" and does not display the text content "change picture".

[0064] The back screen wallpaper bar 334 can include, but is not limited to, an add control 334A, a wallpaper 334B, a wallpaper 334C, and a wallpaper 334D. The electronic device can display more selectable wallpapers in response to a left swipe operation on the back screen wallpaper bar 334. Among them, the wallpaper 334B displays a preview of wallpaper 1, the wallpaper 334C displays a preview of wallpaper 2, and the wallpaper 334D displays a preview of wallpaper 3. For example, the electronic device can set the lock screen wallpaper displayed on the back screen to wallpaper 1 in response to a click operation on the wallpaper 334B.

[0065] The back screen signature type bar 335 can include, but is not limited to, no type 335A, type 335B, type 335C, and type 335D. The electronic device can display more selectable back screen signature types in response to a left swipe operation on the back screen signature type bar 335. Among them, the type 335B displays a preview of the back screen signature of type 1, the type 335C displays a preview of the back screen signature of type 2, and the type 335D displays a preview of the back screen signature of type 3. For example, the electronic device can set the back screen signature displayed on the lock screen wallpaper on the back screen to type 1 in response to a click operation on the type 335B. In some implementations, the type of the back screen signature can be used to indicate that the size of each character in the back screen signature is consistent or inconsistent, the gap between each character, and the arrangement of each character, and the like.

[0066] The back screen signature input box 336 is used to generate a back screen signature in response to a user input operation. The back screen signature can be displayed on the displayed lock screen wallpaper of the back screen.

[0067] The back screen signature color bar 337 can include, but is not limited to, red 337A, orange 337B, yellow 337C, green 337D, cyan 337E, black 337F, and the like. Among them, the selectable color of the back screen signature is not limited to the above single color, but can also be a gradient color and the like. The electronic device can display more selectable colors of the text of the back screen signature in response to a left swipe operation acting on the back screen signature color bar 337.

[0068] The alignment mode bar 338 can include, but is not limited to, alignment control 338A, alignment control 338B, alignment control 338C, alignment control 338D, alignment control 338E, and alignment control 338F. Since the back screen signature can be displayed at any position in the back screen, the user can set the position of the back screen signature by himself. Among them, the alignment control 338A is used to indicate the left alignment mode, the alignment control 338B is used to indicate the center alignment mode relative to the left and right alignment, the alignment control 338C is used to indicate the right alignment mode, the control 338D is used to indicate the top alignment mode, the alignment control 338E is used to indicate the center alignment mode relative to the top and bottom alignment, and the alignment control 338F is used to indicate the bottom alignment mode. The electronic device can determine the position of the back screen signature displayed on the back screen by selecting one alignment mode from the alignment control 338A, the alignment control 338B, and the alignment control 338C, and selecting one alignment mode from the alignment control 338D, the alignment control 338E, and the alignment control 338F.

[0069] The font size sliding control 339 is used to change the size of the font of all the text in the back screen signature in response to a user operation. The electronic device can decrease the font size of the text in the back screen signature in response to a left swipe operation acting on the font size sliding control 339; the electronic device can increase the font size of the text in the back screen signature in response to a right swipe operation acting on the font size sliding control 339.

[0070] The font thickness sliding control 341 is used to change the thickness of the font of all the text in the back screen signature in response to a user operation. The electronic device can decrease the font thickness of the text in the back screen signature in response to a left swipe operation acting on the font thickness sliding control 341; the electronic device can increase the font thickness of the text in the back screen signature in response to a right swipe operation acting on the font thickness sliding control 341.

[0071] The side text type bar 342 may include, but is not limited to: no type 342A, type 342B, and type 342C. The electronic device can respond to a left swipe operation on the side text type bar 342 to display more selectable side text types. Type 342B displays side text of type 1 with a preview, and type 342C displays side text of type 2 with a preview. For example, in response to a click operation on type 342B, the electronic device can set the side text displayed in the side area to type 1. In some implementations, the side text type can be used to indicate whether the size of each character in the back screen signature is consistent or inconsistent, the spacing between each character, etc.

[0072] The side text input box 343 is used to respond to user input and generate side text. This side text can be displayed on the side area.

[0073] The side text color bar 344 can include, but is not limited to: red 344A, orange 344B, yellow 344C, green 344D, cyan 344E, black 344F, etc. Electronic devices can respond to a left swipe operation on the side text color bar 344 to display more selectable side text colors.

[0074] The restore control 345 can be used to restore the previous settings for the lock screen wallpaper displayed on the back screen and the lock screen text displayed in the side area. In other words, it deletes the current settings for the lock screen wallpaper displayed on the back screen and the lock screen text displayed in the side area.

[0075] Application control 346 can be used to save the settings for the lock screen wallpaper displayed on the back screen and the lock screen text displayed in the side area.

[0076] For example, the electronic device displays the user interface 340 in response to a click operation on the back screen preview area 331, or on the selection of the image control 333, or on the addition of the control 334A.

[0077] like Figure 3E As shown, the user interface 340 can be the user interface provided by a photo album application in an electronic device. The user interface 340 may include, but is not limited to, photo 347 and other photos.

The user can also make a series of settings on the lock screen wallpaper and the side text. In this way, the personalized needs of the user can be met.

[0087] Scenario two: The electronic device sets the lock screen wallpaper and / or the desktop wallpaper.

[0088] ​Figures 4A to 4J The related user interface for setting lock screen wallpaper and desktop wallpaper in the embodiments of the present application is shown.

[0089] As shown in Figure 4A , the user interface 400 is a user interface provided by a settings application of the electronic device. The electronic device can display the user interface 400 in response to a settings icon in the desktop. The user interface 400 can include a plurality of function bars, such as the desktop and wallpaper 401. The electronic device can display the user interface 410 in response to a click operation on the desktop and wallpaper 401.

[0090] As shown in Figure 4B , the user interface 410 is a user interface provided by the electronic device for setting functions related to the desktop and lock screen display. The user interface 410 can include, but is not limited to, the theme control 411, the screen off display control 412, the magazine lock screen control 413, the wallpaper control 414, and the icon control 415. The theme control 411 can be used to switch to a user interface for selecting a theme and setting functions related to the theme. The screen off display control 412 can be used to switch to a user interface for setting functions related to the screen off display. The magazine lock screen control 413 can be used to switch to a user interface for viewing and selecting a magazine lock screen. The icon control 415 can be used to switch to a user interface for adjusting the size and style of the icons. In the embodiments of the present application, the content in the user interface 400 is not limited, and the functions of the above controls are not limited. For example, the electronic device can display the user interface 420 in response to a click operation on the wallpaper control 414.

[0091] As shown in Figure 4C , the user interface 420 is a user interface provided by the electronic device for selecting a wallpaper. The user interface 420 can include, but is not limited to, the wallpaper 421, the more wallpaper control 422, and a plurality of other wallpapers. The wallpaper 421 can display a preview of a portion a of the wallpaper A by default. The more wallpaper control 422 can be used by the electronic device to download more wallpapers. The electronic device can display the user interface 430 in response to a click operation of the user on the wallpaper 421.

[0092] As shown in Figure 4D , the user interface 430 is a user interface for previewing the portion a of the wallpaper A in full screen. The user interface 430 can include, but is not limited to, the preview date and time 431, the wallpaper 432, the confirm control 433, and the cancel control 434. The preview date and time 431 is not necessarily the current date and time, but is only for demonstration. The wallpaper 432 displays the portion a of the wallpaper A. The cancel control 434 can restore the last related settings for the wallpaper, i.e., delete the related settings for the portion a of the wallpaper A. The confirm control 433 is used to save the current related settings for the portion a of the wallpaper A.

[0093] In some embodiments, before the electronic device responds to the click operation on the determination control 433, the electronic device can also change the wallpaper 432 in the user interface 430. For example, the electronic device can display the user interface 440 in response to a two-finger slide operation on the wallpaper 432, the two-finger slide operation being along a straight line and moving away from each other.

[0094] As shown in Figure 4E , the user interface 440 is a user interface after the a portion of the wallpaper A is enlarged. The user interface 440 can include, but is not limited to, a preview date and time 441, a wallpaper 442, a determination control 443, and a cancel control 444. The wallpaper 442 displays the content in the dashed box in Figure 4D . The electronic device can display the user interface 450 in response to a click operation on the determination control 443.

[0095] As shown in Figure 4F , the user interface 450 is a user interface provided by the electronic device for determining to set the preview wallpaper as the desktop wallpaper and / or the lock screen wallpaper. The user interface 450 can include, but is not limited to, a preview date and time 451, a wallpaper 452, a home screen lock screen wallpaper preview 453, a desktop wallpaper preview 454, a check control 455, a setting control 456, a setting control 457, and a setting control 458. The preview date and time 451 and the wallpaper 452 can refer to the content described above with reference to Figure 4E . The wallpaper 452 is the same as the wallpaper 442. The home screen lock screen wallpaper preview 453 displays the preview date and time 441 and the wallpaper 442 after being reduced in the same ratio. The desktop wallpaper preview 454 displays the wallpaper 442 and some preview icons after being reduced in the same ratio. The check control 455 can be used to determine to set the wallpaper as the surround lock screen wallpaper and / or the surround desktop wallpaper. For example, the check control 455 also includes a prompt information 455A displaying the text content “Set as home screen lock screen surround wallpaper”. The setting control 456 is used to save the home screen lock screen wallpaper preview 453 as the home screen lock screen wallpaper. For example, the setting control 456 displays the text content “Set as home screen lock screen”. The setting control 457 is used to save the desktop wallpaper preview 454 as the desktop wallpaper. For example, the setting control 457 displays the text content “Set as desktop”. The setting control 458 is used to save the home screen lock screen wallpaper preview 453 as the home screen lock screen wallpaper and save the desktop wallpaper preview 454 as the desktop wallpaper. For example, the setting control 458 displays the text content “Set at the same time”. The electronic device can display the user interface 460 in response to a click operation on the check control 455.

[0096] As shown in Figure 4GAs shown, user interface 460 is a user interface provided to an electronic device for determining whether to set a preview wallpaper as the desktop wallpaper and / or lock screen wallpaper. User interface 460 may include, but is not limited to: preview date and time 461, wallpaper 462, back screen wallpaper preview image 463, home screen lock screen wallpaper preview image 464, desktop wallpaper preview image 465, checkbox control 466, setting control 467, setting control 468, and setting control 469. In user interface 460, when checkbox control 466 is selected, the electronic device can determine whether to set the wallpaper to surround the lock screen and / or surround the desktop. In this case, wallpaper 462 is no longer displayed as... Figure 4D The enlarged content within the dashed box is displayed as the default wallpaper 432, which is part a of wallpaper A. Similarly, the home screen lock screen wallpaper preview 464 displays a proportionally scaled-down preview of the date and time 461 and wallpaper 462. The desktop wallpaper preview 465 displays a proportionally scaled-down wallpaper 462 and some preview icons. The back screen wallpaper preview 463 displays part b of wallpaper A. It can be seen that the back screen wallpaper preview 463 and the home screen lock screen wallpaper preview 464 can form a wraparound lock screen wallpaper, and the back screen wallpaper preview 463 and the desktop wallpaper preview 465 can form a wraparound desktop wallpaper. The settings control 467 is used to save the back screen wallpaper preview 463 and the home screen lock screen wallpaper preview 464 as wraparound lock screen wallpapers. For example, the settings control 467 displays the text "Set as wraparound lock screen". The settings control 468 is used to save the back screen wallpaper preview 463 and the desktop wallpaper preview 465 as wraparound desktop wallpapers. For example, the settings control 457 displays the text "Set as wraparound desktop". The settings control 469 is used to save the back screen wallpaper preview image 463 and the home screen lock screen wallpaper preview image 464 as wraparound lock screen wallpapers and to save the back screen wallpaper preview image 463 and the desktop wallpaper preview image 465 as wraparound desktop wallpapers. For example, the settings control 469 displays the text "Set simultaneously".

[0097] In one possible implementation, when the electronic device selects control 466, meaning the electronic device can determine whether to set a wraparound lock screen wallpaper and / or a wraparound desktop wallpaper, setting controls 467 and 468 are grayed out, meaning they cannot respond to user operations. In other words, the current electronic device may only support setting both a wraparound lock screen wallpaper and a wraparound desktop wallpaper simultaneously. This is not limited in the embodiments of this application.

[0098] In some implementations, when an electronic device has a wraparound lock screen wallpaper and / or a wraparound desktop wallpaper set, a portion of the wallpaper will also be displayed on the side of the electronic device.

[0099] refer to Figure 4H , Figure 4HAn example diagram shows an electronic device displaying a wraparound wallpaper. Figure 4H The area displaying the surrounding wallpaper can be divided into three regions: the first region is the back screen display area, the second region is the side display area, and the third region is the main screen display area. For example... Figure 4H As shown, the first area displays content that can be part a of wallpaper A, the third area displays content that can be part b of wallpaper A, and the second area displays content that can be part c of wallpaper A. The content displayed in these three areas can constitute the entire wallpaper A. In this way, when the electronic device is in a folded state, the electronic device can see the wallpaper surrounding the lock screen and / or the wallpaper surrounding the desktop, providing a good viewing experience for the user.

[0100] For example, the electronic device can respond to a click operation on the checkbox 466, deselect the checkbox 466, and display the user interface 450. That is, after the electronic device cancels the setting of the wraparound wallpaper, it can preview the home screen lock screen preview and desktop preview that were previously zoomed in on the wallpaper.

[0101] Electronic devices can also be used to Figure 4B The theme control 411 in the middle displays the user interface 470. For example... Figure 4I As shown, user interface 470 is a user interface provided by the electronic device for selecting a theme. User interface 470 may include, but is not limited to, theme 471 and multiple other themes. Theme 471 may, by default, display a preview image of part a of a wallpaper belonging to the metallic theme. The electronic device can respond to a user's click operation on theme 471 and display user interface 480. (The rest of the text is missing.) Figure 4J As shown, user interface 480 is a user interface for previewing and selecting the metal theme. User interface 480 may include, but is not limited to: back screen preview image 481, main screen preview image 482, theme introduction 483, and application controls 484. Back screen preview image 481 displays part b of the wallpaper belonging to the metal theme. Main screen preview image 482 displays part a of the wallpaper belonging to the metal theme. Theme introduction 483 is used to introduce the metal theme. For example, theme introduction 483 displays the text "Preset theme supports dark mode main screen wraparound wallpaper". The electronic device can respond to a click operation on application control 484 to set the theme of the electronic device to the metal theme. The wraparound lock screen wallpaper and wraparound desktop wallpaper of the electronic device are both set to wraparound wallpapers belonging to the metal theme, such as the content shown in back screen preview image 481 and main screen preview image 482. Optionally, the wallpaper belonging to the preset theme of the electronic device cannot be resized for display on the main screen or back screen; that is, when the electronic device uses a wallpaper belonging to the preset theme, the displayed wraparound wallpaper is the entire wallpaper belonging to the preset theme, not just a part of it.

[0102] Case three: the electronic device sets lock screen wallpaper and / or desktop wallpaper under the premise that the electronic device sets lock screen wallpaper for the back screen and sets lock screen text for the side area. Case three can be further divided into two types: (a) the lock screen wallpaper and / or desktop wallpaper does not belong to the preset theme of the electronic device; (b) the lock screen wallpaper and / or desktop wallpaper does not belong to the preset theme of the electronic device.

[0103] The following first introduces case three of type (a): Figures 5A-5C An exemplary user interface provided by the electronic device when in case three is shown.

[0104] The electronic device can set lock screen wallpaper for the back screen and set lock screen text for the side area in response to a click operation on the application control 366. Thereafter, the electronic device can view the user interface 500.

[0105] As shown in Figure 5A , the user interface 500 includes the same elements as the user interface 320. The user interface 500 can include, but is not limited to, a back screen preview area 501, a side preview area 502, a change style control 503, and an on control 504. The back screen preview area 501 displays the photo 347 and the text content “Tomorrow will be better”, the side preview area 502 displays the text content “Be A Better Man”, and the on control 504 is used to indicate that the current electronic device has enabled the personalized back screen and side display function. Thereafter, the electronic device can perform the exemplary operation described above with respect to Figures 4A to 4F , and display the user interface 510 in response to a click operation on the check control 455.

[0106] As shown in Figure 5B , the user interface 510 can include, but is not limited to, a check control 511, which can be used to determine whether to set a wrap-around lock screen wallpaper and / or a wrap-around desktop wallpaper. In the case where the electronic device has enabled the personalized back screen and side display function, the electronic device can display a prompt information 511A during the determination of setting the wrap-around wallpaper. Exemplarily, the check control 511 further includes the prompt information 511A displaying the text content “Set as the main back screen wrap-around wallpaper at the same time, which will replace the personalized back screen and side display”. In this way, the user can be reminded whether to replace the previously set back screen lock screen and side text with the current wrap-around wallpaper. The electronic device can set the current wallpaper as the wrap-around wallpaper in response to a user operation. Thereafter, the electronic device can view the user interface 520.

[0107] As shown in Figure 5CAs shown, the user interface 520 includes the same elements as the user interface 500. The user interface 520 can include, but is not limited to, a back screen preview area 521, a side preview area 522, a change style control 523, an enable control 524, and a prompt 525. In a case where the electronic device has replaced the back screen lock screen wallpaper and the side text set by the user before the current wrap wallpaper, the enable control 524 is in a closed state, indicating that the current electronic device has closed the enable personal back screen and side display function. And the prompt 525 is used to prompt the user that if the user acts on the enable control, the content displayed in the back screen preview area 521 and the side preview area 522 will be replaced by the content displayed in the last set wrap wallpaper in the back screen and side area, but the content displayed in the main screen will not be replaced.

[0108] The following first introduces case three belonging to type (b): Figure 5D -FIG. 5F exemplarily shows a user interface provided by the electronic device in case three.

[0109] The electronic device can respond to the click operation on the application control 366 to set the lock screen wallpaper for the back screen and set the lock screen text for the side area. After that, the electronic device can view the user interface 530.

[0110] As shown, the user interface 530 is consistent with the user interface 500, and the related description introduced above Figure 5D will not be repeated here. After that, the electronic device can perform the exemplary operations in the above Figure 5A , Figure 4A , Figure 4B and Figure 4I , and display the user interface 540 in response to the click operation on the application control 484.

[0111] As shown, the user interface 540 is consistent with the user interface 500, and the related description introduced above Figure 5EAs shown, the user interface 540 can include, but is not limited to, a back screen preview image 541, a home screen preview image 542, a theme introduction 543, and a prompt box 544. The prompt box 544 includes prompt information 544A, a control 544B, and a control 544C. For example, the prompt information 544A displays the text content "After switching the theme, do you want to replace the personal back screen and side display?". The control 544B can display the text content "Do not replace", which indicates that the electronic device will not replace the surrounding wallpaper in the currently set metal theme with the back screen lock screen wallpaper and the side text set last time. That is, after responding to the click operation on the control 544B, when the electronic device is in the lock screen bright screen state, the last set back screen lock screen wallpaper can be displayed on the back screen, the last set side text can be displayed on the side area, and the currently set home screen lock screen wallpaper belonging to the metal theme can be displayed on the home screen. The control 544C can display the text content "Replace", which indicates that the electronic device will replace the surrounding wallpaper in the currently set metal theme with the back screen lock screen wallpaper and the side text set last time. That is, after responding to the click operation on the control 544C, when the electronic device is in the lock screen bright screen state, the currently set surrounding lock screen wallpaper belonging to the metal theme can be displayed on the home screen, the back screen, and the side area. After the electronic device sets the current wallpaper as the surrounding lock screen wallpaper belonging to the metal theme, the electronic device can view the user interface 520. For related descriptions of the user interface 520, refer to the above content, which is not limited herein.

[0112] In the embodiments of the present application, the above user interface is only illustratively described, and the above user interface can include more or less content, which is not limited herein.

[0113] The embodiments of the present application provide a display wallpaper method and related apparatus. In the method, the electronic device can first determine the region of the display wallpaper as the back screen and the side area, and then determine the displayed wallpaper when the electronic device is in the lock screen bright screen state. Alternatively, the electronic device can first determine the displayed wallpaper, and then determine whether to display the wallpaper in the lock screen bright screen state or in the unlock bright screen state, and whether to display the wallpaper only on the home screen or on the home screen, the back screen, and the side area.

[0114] Implementing the above method can individually set the wallpaper displayed on the back screen and the side area in the lock screen bright screen state, and can also set the surrounding wallpaper, which is more beautiful. In this way, the user can set the wallpaper displayed on each screen in different states in the electronic device according to personal preferences, fully meeting the personalized needs of the user.

[0115] The display wallpaper method provided by the embodiments of the present application will be described below in combination with Figure 6 Figure 6 ​The method execution subject shown can be the electronic device mentioned above. Alternatively, Figure 6 The method execution subject shown can be a chip in the electronic device, and embodiments of the present application are not limited thereto. Figure 6 An electronic device is taken as an example to illustrate the method. The electronic device includes a display screen, and the display screen includes a main screen and a back screen, which are two display areas of the same display screen. When the electronic device is folded, the main screen and the back screen face opposite directions. When the electronic device is unfolded, the main screen and the back screen face the same direction, and the display area is the entire display screen. The method includes the following steps.

[0116] S601, the electronic device sets a first wallpaper as a back screen lock screen wallpaper and sets a first text as a side lock screen text.

[0117] The back screen lock screen wallpaper can refer to a wallpaper displayed on the back screen when the electronic device is in a lock screen bright screen state.

[0118] The first wallpaper can be provided by a system application in the electronic device or by a third-party application (for example, an album application) in the electronic device, and embodiments of the present application are not limited thereto.

[0119] In some implementations, the electronic device can also set the first wallpaper as the back screen lock screen wallpaper in response to a user operation. Before the electronic device sets the first wallpaper as the back screen lock screen wallpaper, the electronic device can display the first wallpaper with a preview. The electronic device can rotate, zoom, or perform other operations on the first wallpaper with a preview to obtain the first wallpaper in response to a user operation.

[0120] In a possible implementation, the electronic device can also add a back screen signature to the back screen lock screen wallpaper in response to a user operation, and the back screen signature is displayed on an upper layer of the wallpaper. Before adding the back screen signature, the electronic device can generate the back screen signature. Generating the back screen signature can include, but is not limited to, determining text content of the back screen signature, determining a color of the back screen signature, determining a style type of the back screen signature, determining a font size of the back screen signature, determining a font thickness of the text of the back screen signature, and determining a display position of the back screen signature.

[0121] In some implementations, the electronic device can also set the first text as the side lock screen text in response to a user operation. Before the electronic device sets the first text as the side lock screen text, the electronic device can generate the first text. Generating the first text can include, but is not limited to, determining text content of the first text, determining a style type of the first text, and determining a color of the first text.

[0122] S602, the electronic device switches from the screen-off state to a lock screen off state.

[0123] In some implementations, the electronic device can perform S601 in a screen-on state. The electronic device switches from the screen-on state to a lock screen-off state in response to a user operation. The user operation can be a lock screen operation, which can include, but is not limited to, a press operation on a lock screen button on a side or top edge of the electronic device, a click operation on a lock screen control in a user interface, a voice instruction, a gesture instruction, and the like.

[0124] S603, after the electronic device switches from the lock screen-off state to a lock screen-on state, the electronic device displays a first wallpaper on the back screen and a first text on the side area.

[0125] In some implementations, the electronic device can switch from the lock screen-off state to the lock screen-on state when a screen-on condition is met. The screen-on condition can include, but is not limited to, the electronic device receiving a double-tap screen operation when the electronic device is in a double-tap screen-on mode, detecting a user picking up the electronic device operation when the electronic device is in a lift-up screen-on mode, and the like. After the electronic device switches to the lock screen-on state, the electronic device can display a first wallpaper on the back screen and a first text on the side area, and the content displayed on the home screen can be a home screen lock screen wallpaper set by the electronic device. For the home screen lock screen wallpaper, please refer to the following content, and the details are not described here.

[0126] Optionally, after the electronic device switches from the power-off state to the lock screen-on state, the electronic device can also display a first wallpaper on the back screen and a first text on the side area.

[0127] As can be seen from the above method flow, the electronic device can separately set the content displayed on the back screen and the side area in the lock screen-on state. In this way, the user can set the content displayed on the back screen and the side area in the lock screen-on state according to personal preferences, and experience personalized settings.

[0128] The following will be described with reference to Figures 7A-7F to introduce another method for displaying a wallpaper provided by an embodiment of the present application.

[0129] S701, the electronic device sets a second wallpaper as a surround lock screen wallpaper and a surround desktop wallpaper. In the surround lock screen wallpaper and the surround desktop wallpaper, the back screen is used to display a first part of the second wallpaper, the home screen is used to display a second part of the second wallpaper, and the side area is used to display a third part of the second wallpaper.

[0130] The surround lock screen wallpaper described above can refer to a wallpaper displayed on the home screen, the back screen, and the side area at the same time when the electronic device is in a lock screen-on state. The surround desktop wallpaper described above can refer to a desktop wallpaper displayed on the home screen, the back screen, and the side area at the same time when the electronic device is in an unlocked screen-on state.

[0131] The second wallpaper can be provided by a system application in the electronic device.

[0132] In a possible implementation, the wrap-around lock screen wallpaper can be displayed completely when the electronic device is in the folded state or in the unfolded state, and the wrap-around desktop wallpaper can be displayed completely when the electronic device is in the unfolded state. This is because when the electronic device is in the folded state, when the electronic device is in the unlocked and screen-on state, only one of the main screen and the back screen can be lit, and the main screen and the back screen can not be lit at the same time. Therefore, when the electronic device is in the folded state, when the electronic device is in the lock screen and screen-on state, if the current electronic device displays a user interface on the main screen, the first part of the wrap-around desktop wallpaper can be displayed on the main screen; if the current electronic device displays a user interface on the back screen, the second part of the wrap-around desktop wallpaper can be displayed on the back screen. That is, the wrap-around desktop wallpaper can be partially displayed when the electronic device is in the folded state.

[0174] In a possible implementation, after the electronic device is in the unlock screen-bright screen state and is switched from displaying any other user interface to displaying the desktop, the electronic device can also display the desktop wallpaper.

[0175] It is worth noting that because the sizes of the main screen and the back screen are different, even if the same wallpaper is displayed, the displayed content will be different. In addition, when the electronic device sets the desktop wallpaper, the size of the main screen is used for setting. In the embodiments of the present application, two methods of how to display the same wallpaper on the back screen as on the main screen are provided: cropping or equal ratio reduction.

[0176] As shown in the above Figure 2 It is assumed that the width of the wallpaper B displayed in the main screen is w2, the height is h, and the coordinate center of the same wallpaper is (w2 / 2, h / 2). Because when the electronic device sets the wallpaper B as the desktop wallpaper, the wallpaper B needs to be displayed on the back screen.

[0177] If the cutting method is used, the width of the wallpaper B needs to be changed from w2 to the back screen width w1. That is, two regions with a length of (w2-w1) / 2 and a height of h need to be cut off from the two ends of the wallpaper B in length, so that the midpoint of the wallpaper B' after cutting is consistent with the midpoint of the wallpaper B, and the width of the wallpaper B' is w1 and the height is h.

[0178] If the method of equal proportional reduction is used, the length w2 and the height h of the wallpaper B need to be reduced by times. That is, the width of the wallpaper B'' after equal proportional reduction is w1, and the height is h*(w1 / w2). In this case, the area of the back screen except for displaying the wallpaper B'' also needs to be filled, and the midpoint of the wallpaper B'' displayed on the back screen is consistent with the midpoint of the back screen.

[0179] In the embodiments of the present application, more methods of displaying the same wallpaper on the back screen as the main screen back screen can also be included, and the above two methods are only exemplary and are not limited.
