Any embodiment or design scheme described as an “exemplary” or “for example” in this application should not be explained as being more preferred or having more advantages than another embodiment or design scheme. Exactly, the terms such as “exemplary” and “for example” as used herein are intended to present the related concept in a specific implementation.

In this application, “at least one” refers to one or more, and “a plurality of” refers to two or more. The term and/or describes an association relationship for describing associated objects and represents that three relationships may exist. For example, A and/or B may represent: only A exists, both A and B exist, and only B exists, where A and B may be singular or plural. The character “/” generally indicates an “or” relationship between the associated objects. “At least one of the following items” or a similar expression means any combination of these items, including a single item (item) or any combination of a plurality of items (items). For example, at least one of a, b, or c may represent: a, b, c, a-b, a-c, b-c, or a-b-c, where a, b, and c may be single or multiple.

With the development of a flexible screen technology, a flexible foldable screen (also referred to as a foldable screen) has been applied to a mobile phone and other terminal devices. A terminal device using the foldable screen can include an internal display and an external display, and the internal display can be folded.

Wallpapers can be set on a desktop of the internal display and a desktop of the external display separately to meet different aesthetic needs of users. However, when the user sets the desktop of the internal display and the desktop of the external display, setting steps are cumbersome and inefficient, which affects the user experience.

As shown in FIG. 1A, an internal display of an electronic device 100 displays a function setting interface 101, and the function setting interface 101 includes a desktop and wallpaper option 102. As shown in FIG. 1A and FIG. 1B, the electronic device 100 displays a plurality of images in response to a user's click operation on the desktop and wallpaper option 102. As shown in FIG. 1B and FIG. 1C, the electronic device 100 may select an image 103 and display an application button 104 in response to a user's click operation on the image 103 in the plurality of images. As shown in FIG. 1C and FIG. 1D, the electronic device 100 sets a wallpaper of a desktop 105 of the internal display of the electronic device 100 based on the image 103 in response to a click operation on the application button 104 by the user.

In order to make an external display of the electronic device 100 also set a wallpaper based on the image 103, when a “Setting icon” of a desktop of the external display of the electronic device 100 is triggered by a user, as shown in (a) in FIG. 2, the external display of the electronic device 100 displays a function setting interface 201, and the function setting interface 201 includes a desktop and wallpaper option 202. The electronic device 100 displays an image selection interface 203 in response to a user's click operation on the desktop and wallpaper option 202. The image selection interface 203 includes a plurality of images. As shown in (a) and (b) in FIG. 2, the electronic device 100 may select an image 204 and display an application button 205 in response to a user's click operation on the image 204 (namely, the image 103) in the plurality of images. As shown in (c) and (d) in FIG. 2, the electronic device 100 sets a wallpaper of a desktop 206 of the external display of the electronic device 100 based on the image 204 in response to a click operation on the application button 205 by the user.

It can be learned that in the above process, if wallpapers are set on the internal display and the external display of the electronic device 100 based on a same image, the operation process is cumbersome, the efficiency is low, and the user experience is affected.

In other scenarios, the electronic device 100 may alternatively crop or stretch the wallpaper of the desktop 105 of the internal display, and the wallpaper of the desktop 206 of the external display of the electronic device 100 is obtained. This causes deformation of the wallpaper of the desktop 206 of the external display.

In view of this, this application provides a wallpaper setting method. A second interface displayed by the electronic device includes a first wallpaper, a second wallpaper and a first control. The first wallpaper and the second wallpaper are different wallpapers generated based on a same image. The electronic device sets the first wallpaper as a wallpaper of a first display and sets the second wallpaper as a wallpaper of a second display in response to a second operation on the first control on the second interface. That is, a user can set the first wallpaper of the first display and the second wallpaper of the second display through one trigger, which is convenient and quick to operate and has high efficiency.
