Description

[Technical Field]

[0001] This application claims priority to Chinese Patent Application No. 202010072042.1, entitled "Display Method and Related Device for Foldable Screen," filed with the State Intellectual Property Office of China on January 21, 2020, which is incorporated herein by reference in its entirety.

[0002] The present application relates to the field of electronics, and more particularly to a display method for a foldable screen and related devices. [Background technology]

[0003] With the continuous development of electronic devices, the number of electronic devices with displays, such as mobile phones with displays, is increasing and is being applied to people's daily lives and work. In addition, with the development of screen technology, the displays of electronic devices are also becoming larger to provide users with more information and bring users a better user experience.

[0004] However, if the display of an electronic device is too large, it will significantly affect the portability of the electronic device. Therefore, electronic devices with foldable screens (e.g., foldable mobile phones) have been proposed in recent years, which are in line with the future development trend of electronic devices.

[0005] Currently, the form of a foldable screen may include a folded state and an unfolded state. When the foldable screen is in the folded state, the foldable screen may be folded to form at least two screens. The electronic device may display an application interface on one of the screens. After the foldable screen is unfolded, the display area of ​​the foldable screen includes at least two screens. The electronic device may display the application interface on the entire display area of ​​the foldable screen. Currently, the foldable screen has only two forms, and the application interface can only be fixedly displayed at a specified position on the foldable screen. This lacks flexibility. Summary of the Invention

[0006]

[0003] The present application provides a display method and a related apparatus for a foldable screen. As a result, when a camera is turned on for a foreground application running on an electronic device and the foldable screen of the electronic device is changed to a half-folded configuration, the electronic device can display the application interface of the foreground application on half of the foldable screen. In this way, a user can conveniently take photos, make video calls, or live broadcasts without having to hold the electronic device steadily with both hands.

[0007] According to a first aspect, an embodiment of the present application provides a display method for a foldable screen, which is applied to an electronic device including the foldable screen. The foldable screen can be folded to form a first screen and a second screen. The method includes a step in which, when the foldable screen is in an unfolded configuration, the electronic device displays a first interface of a first application in full screen on the foldable screen. The first interface includes an image captured by a camera, and the image captured by the camera is an image captured before a capture confirmation signal is received. When detecting that the foldable screen is changing from the unfolded configuration to the half-folded configuration, the electronic device displays a second interface on the first screen. Content displayed in the second interface is the same as or different from the content displayed in the first interface. When the foldable screen is in the unfolded configuration, the included angle between the first screen and the second screen is greater than a first angle threshold, and when the foldable screen is in the half-folded configuration, the included angle between the first screen and the second screen is between the first angle threshold and a second angle threshold, the first angle threshold being greater than the second angle threshold.

[0008] According to the display method for a foldable screen provided in this embodiment of the present application, when the foldable screen of an electronic device is in a half-folded state, if a foreground application (e.g., a camera application or a WeChat® application) running on the electronic device that supports window display adaptation launches the camera, the electronic device may display the application interface of the foreground application on the first screen or the second screen of the foldable screen. In this way, a user can conveniently take photos, make video calls, or live broadcasts without having to hold the electronic device steadily with both hands.

[0009] In a possible implementation, the method further includes the electronic device displaying a second interface on the second screen when the foldable screen is in a half-folded configuration and the included angle between the plane on which the first screen is located and the horizontal plane is less than a third angle threshold. The third angle threshold is less than the second angle threshold. In this way, when photographing the sky or the ground on a tall building, the user does not need to look up and be blinded by the sun or look down, and the electronic device automatically displays a higher-layer application interface for activating the camera on the half-screen (e.g., the second screen) that is approximately perpendicular to the horizontal plane, making it easier for the user to take a photograph.

[0010] In a possible implementation, if the period during which the included angle between the first screen and the second screen remains between the first angle threshold and the second angle threshold is greater than the first time threshold, the electronic device detects that the foldable screen is changing to the half-folded configuration. In this way, the electronic device can accurately identify that the user wants the foldable screen to enter the half-folded configuration, thereby improving the accuracy of the determination.

[0011] In a possible implementation, the electronic device further includes a third screen, and when the foldable screen is folded, the third screen and the first screen face away from each other. The method further includes, after the electronic device activates the time-lapse photography function, receiving a first user input via the second interface. In response to the first input, the electronic device displays a countdown prompt on the first screen and the third screen. The countdown prompt is used to prompt the user of the remaining time for the electronic device to capture an image captured by the camera. In this way, when the owner leaves the electronic device and performs automatic countdown photography with another person, the countdown can be displayed on the third screen. This makes it convenient for the user to assume a photography position, thereby improving the user experience.

[0012] In a possible implementation, the method further includes, in response to the first input, the electronic device displaying an image captured by the camera on a third screen.

[0013] In one possible implementation, the first application is associated with a second application, and the method further includes the electronic device displaying a third interface of the second application on the second screen when detecting that the foldable screen is changing from the unfolded configuration to the semi-folded configuration. In this way, the application associated with the first application can be quickly launched, thereby improving the user experience.

[0014] In a possible implementation, the first application corresponds to a plurality of associated applications, and the method further includes, when detecting that the foldable screen is changing from the unfolded configuration to the semi-folded configuration, the electronic device displays options of the plurality of associated applications on the second screen. The electronic device receives a second user input for an option corresponding to the second application. In response to the second input, the electronic device displays a third interface of the second application on the second screen.

[0015] In a possible implementation, the method further includes the electronic device displaying the switch control on the first screen or the second screen. The electronic device receives a third input from the user on the switch control. In response to the third input, the electronic device displays a third interface on the first screen and a second interface on the second screen. In this way, the interface displayed on the first screen and the interface displayed on the second screen can be switched based on a user request, thereby improving the user experience.

[0016] In a possible implementation, the first interface further includes one or more operation controls, and the electronic device displays a fourth interface on the second screen when it detects that the foldable screen is changing from the unfolded configuration to the semi-folded configuration.

[0048] Hereinafter, the technical solutions in the embodiments of the present application will be clearly described in detail with reference to the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " indicates "or". For example, A / B may indicate A or B. The term "and / or" in this specification merely describes the correspondence between related objects and indicates that three relationships may exist. For example, A and / or B may indicate three cases: only A exists, both A and B exist, and only B exists. In addition, in the description of the embodiments of the present application, "multiple" means two or more.

[0049] The following terms, "first" and "second," are intended for descriptive purposes only and shall not be understood as an indication or suggestion of relative importance or an implicit indication of the number of technical features shown. Thus, a feature qualified by "first" or "second" may explicitly or implicitly include one or more features. In the description of embodiments of this application, unless otherwise specified, "plurality" means two or more than two.

[0050] An embodiment of the present application provides a display method for a foldable screen. The method may be applied to an electronic device 100 having a foldable screen. The foldable screen may be folded to form at least two screens. For example, the foldable screen may be folded along a folding edge or a folding axis to form a first screen and a second screen.

[0051] The folding manner of the foldable screen on the electronic device 100 can be classified into two types. One type is a foldable screen that folds outward (simply referred to as an outward-facing foldable screen), and the other type is a foldable screen that folds inward (simply referred to as an inward-facing foldable screen). For example, the foldable screen can be folded to form a first screen and a second screen. After the outward-facing foldable screen is folded, the display direction of the first screen and the display direction of the second screen face opposite each other. After the inward-facing foldable screen is folded, the display direction of the first screen and the display direction of the second screen face each other. In this embodiment of the present application, the first screen may be referred to as screen A, and the second screen may be referred to as screen B.

[0052] In this embodiment of the present application, the electronic device 100 uses an inward-facing foldable screen, in other words, the display direction of the first screen and the display direction of the second screen are opposite to each other.

[0053] For example, FIG. 1 is a schematic diagram of a product configuration of an electronic device 100 with an inward-facing foldable screen according to one embodiment of the present application. (a) of FIG. 1 is a schematic diagram of the inward-facing foldable screen in a fully unfolded configuration. The inward-facing foldable screen can be folded along folding edges in directions 11a and 11b shown in (a) of FIG. 1 to form screen A and screen B in a semi-folded configuration shown in (b) of FIG. 1. After the foldable screen is folded into screen A and screen B, screen A and the front-facing camera on electronic device 100 can be on the same side. The inward-facing foldable screen can be folded along folding edges based on screen A and screen B shown in (b) of FIG. 1. The inward-facing foldable screen may continue to fold along the folding edges in directions 12a and 12b shown in Fig. 1(b) to form an outward-facing foldable screen in a fully folded state shown in Fig. 1(c). As shown in Fig. 1(c), after the foldable screen of electronic device 100 is fully folded, screen A and screen B face each other and are not visible to the user.

[0054] It should be noted that a display may be further disposed behind the first or second screen of the inward-facing foldable screen provided in this embodiment of the present application, and may be referred to as a third screen. For example, as shown in (a) of FIG. 2, screen C (i.e., the third screen) may be disposed behind screen A (i.e., the first screen). As shown in (b) of FIG. 2, after the inward-facing foldable screen is fully folded, screen C and screen A face away from each other, and screen C is visible to the user. Screen C and the rear camera on electronic device 100 may be on the same side. It may be understood that in an electronic device 100 having an inward-facing foldable screen, an interface may be displayed on the third screen when the foldable screen is in a fully folded state, an interface may be displayed on the first screen, the second screen and the third screen when the foldable screen is in a half-folded state, or an interface may be displayed on the first screen and the second screen when the foldable screen is in an unfolded state.

[0055] 1 and 2, the foldable screen of the electronic device 100 is folded vertically. That is, the foldable screen is folded into a left screen and a right screen (i.e., screen A and screen B) based on the vertical folding edge of the foldable screen. In one embodiment of the present application, the foldable screen of the electronic device 100 may alternatively be folded horizontally. That is, the foldable screen is folded into an upper screen and a lower screen (i.e., screen A and screen B) based on the horizontal folding edge of the foldable screen. For example, the foldable screen shown in FIG. 3(a) is folded along the horizontal folding edge of the foldable screen to sequentially form the foldable screen shown in FIG. 3(b) and the foldable screen shown in FIG. 3(c) or FIG. 3(d).

[0056] In some embodiments of the present application, a display may be disposed behind the first or second screen of electronic device 100 and may be referred to as a third screen. For example, as shown in (d) of FIG. 3, screen C (i.e., the third screen) may be disposed behind screen A (i.e., the first screen) and may be on the same side of electronic device 100 as the rear camera.

[0057] In some embodiments, the foldable screen of electronic device 100 may surround the outer edge of electronic device 100, and screen A (first screen), screen B (second screen), and screen C (third screen) may all be part of the foldable screen. When the foldable screen is folded, screen A and screen C may face away from each other, and screen A is adjacent to screen B.

[0058] In this embodiment of the present application, the value range of the included angle between screen A and screen B of the foldable screen of the electronic device 100 is [0°, 180°].

[0059] In some embodiments, based on the usage habits of most users, when the included angle α between screen A and screen B is greater than 100°, it is highly likely that the user expects to use screen A and screen B as a whole (i.e., as a complete display). When the included angle α between screen A and screen B is less than 80°, it is highly likely that the user expects to use screen A or screen B independently, and the foldable screen may be in a fully folded form. When the included angle α between screen A and screen B is between 80° and 100°, it is highly likely that the user expects to display different display contents using screen A and screen B, and the foldable screen may be in a half-folded state.

[0060] Therefore, in the present embodiment of the present application, the value range of the preset angle threshold P1 may be (0°, 80°], and the value range of the preset angle threshold P2 may be [100°, 180°). For example, the preset angle threshold P1 may be 75°, and the preset angle threshold P2 may be 105°. The above examples are only used to illustrate the present application and should not be construed as limitations.

[0061] It should be noted that in this embodiment of the present application, the at least two screens formed by folding the foldable screen may be multiple independent screens or may be a complete screen with a unitary structure that is folded to form at least two parts.

[0062] For example, the foldable screen may be a flexible foldable screen, the flexible foldable screen including folding edges made of a flexible material, some or all of the flexible foldable screen being made of a flexible material, and the at least two screens formed by folding the flexible foldable screen are a complete screen of a unitary construction that is folded to form at least two portions.

[0063] In another example, the foldable screen may be a multi-screen foldable screen. The multi-screen foldable screen may include multiple (two or more) screens. The multiple screens are multiple separate displays. The multiple screens may be connected in series through a folding axis. Each screen may rotate around a folding axis connected to the screen, resulting in the multi-screen foldable screen being folded.

[0064] In the subsequent embodiments of the present application, an example in which the foldable screen is a flexible foldable screen that can be folded horizontally will be used to describe the method provided in this embodiment of the present application.

[0065] For example, the electronic device 100 in this embodiment of the present application may be a device including a foldable screen as described above, such as a mobile phone, a tablet computer, a desktop computer, a laptop computer, a handheld computer, a notebook computer, an ultra-mobile personal computer (UMPC), a netbook, a cellular phone, a personal digital assistant (PDA), or an augmented reality (AR) / virtual reality (VR) device.

[0110] In this embodiment of the present application, the display 194 of the electronic device 100 may be folded to form multiple screens. A gyroscope sensor 180B may be disposed on each of the multiple screens and configured to measure the orientation (i.e., the orientation direction vector) of the corresponding screen. The electronic device 100 may determine the included angle between adjacent screens (e.g., the included angle between screen A and screen B) based on the angular change in orientation of each screen measured by the gyroscope sensor 180B.

[0111] It should be noted that in this embodiment of the present application, a foldable screen (e.g., display 194 of electronic device 100) may be folded to form multiple screens. Each screen may include a gyroscope sensor (e.g., gyroscope sensor 180B) configured to measure the orientation (i.e., orientation direction vector) of the corresponding screen. For example, with reference to FIG. 1, FIG. 2, or FIG. 3, display 194 of electronic device 100 may be folded to form screen A (i.e., first screen) and screen B (i.e., second screen). In this case, both screen A and screen B include gyroscope sensors 180B separately configured to measure the orientations of screen A and screen B.

[0112] For example, the foldable screen of the electronic device 100 may be folded to form screen A and screen B shown in Fig. 5A. Gyroscope sensor A is disposed on screen A, and gyroscope sensor B is disposed on screen B. The principles of measuring the orientation of screen A (i.e., the orientation direction vector) by gyroscope sensor A and measuring the orientation of screen B (i.e., the orientation direction vector) by gyroscope sensor B, and the principles of calculating the included angle α between screen A and screen B by electronic device 100 based on the orientation of screen A and the orientation of screen B will be described in this embodiment of the present application.

[0113] The coordinate system of the gyroscope sensor is a geographic coordinate system.

The plane formed by the axes X and Y is the local horizontal plane, and the plane formed by the axes Y and Z is the local meridian plane. Therefore, it can be understood that the coordinate system of the gyroscope sensor is as follows: the gyroscope sensor is used as the origin O, the direction pointing east along the local latitude line is used as the axis X, the direction pointing north along the local meridian is used as the axis Y, and the direction pointing up along the local geographic vertical line (i.e., the backward direction of the geographic vertical line) is used as the axis Z.

[0114] Through measurements using the gyroscope sensors arranged on each screen, the electronic device 100 can recognize the direction vector of the orientation of each screen in the coordinate system of the gyroscope sensors arranged on each screen. For example, see the side view of the electronic device 100 shown in FIG. 5A.

[0117] In some embodiments, the included angle α between screen A and screen B may alternatively be measured in cooperation with one or more other sensors. For example, one acceleration sensor may be disposed on each screen of the foldable screen. Using the acceleration sensors, electronic device 100 (e.g., processor 110) may measure the motion acceleration of each screen as it is rotated, and then calculate the angle at which one screen rotates relative to the other screen, i.e., the included angle α between screen A and screen B, based on the measured motion acceleration.

[0118] In some other embodiments, the gyroscope sensor may be a virtual gyroscope sensor formed in cooperation with multiple other sensors, and may be configured to calculate the included angle α between adjacent screens of the foldable screen, i.e., the included angle α between screen A and screen B.

[0135] The motor 191 may generate a vibration prompt. The motor 191 may be configured to generate an incoming call vibration prompt and touch vibration feedback. For example, touch operations performed in different applications (such as a photography application and an audio playback application) may correspond to different vibration feedback effects. The motor 191 may also correspond to different vibration feedback effects for touch operations performed on different areas of the display 194. Different application scenarios (e.g., time reminders, information reception, alarm clocks, and games) may correspond to different vibration feedback effects. The touch vibration feedback effects may be further customized.

[0136] The indicator 192 may be an indicator light and may be configured to indicate charging status and power changes, and may be configured to indicate messages, missed calls, notifications, and the like.

[0137] The SIM card interface 195 is configured to connect to a SIM card. The SIM card may be inserted into or removed from the SIM card interface 195 to implement contact with or separation from the electronic device 100. The electronic device 100 may support one or N SIM card interfaces, where N is a positive integer greater than one. The SIM card interface 195 may support nano-SIM cards, micro-SIM cards, SIM cards, and the like. Multiple cards may be inserted into the same SIM card interface 195 simultaneously. The multiple cards may be the same type or different types. The SIM card interface 195 may be compatible with different types of SIM cards. The SIM card interface 195 is also compatible with external storage cards. The electronic device 100 interacts with a network through the SIM card to implement functions such as call and data communication. In some embodiments, the electronic device 100 uses an eSIM, i.e., an embedded SIM card. The eSIM card may be embedded in the electronic device 100 and cannot be separated from the electronic device 100.

[0138] The software system of electronic device 100 may use a layered architecture, an event-driven architecture, a microkernel architecture, a microservices architecture, or a cloud architecture. In one embodiment of the present invention, the Android® system, which has a layered architecture, is used as an example to describe the software structure of electronic device 100.

[0139] 7A-1 and 7A-2 are block diagrams of the software architecture of the electronic device 100 according to this embodiment of the present application.

[0140] In a layered architecture, software is divided into several layers, each with a distinct role and task. These layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into four layers: from top to bottom, the application layer, the application framework layer, the Android runtime and system libraries, and the kernel layer.

[0141] The application (APP) layer may include a series of application packages, such as camera, gallery, calendar, phone, map, navigation, WLAN, Bluetooth, music, video, and messaging applications, as shown in Figures 7A-1 and 7A-2.

[0142] The application framework layer provides an application programming interface (API) and a programming framework for applications in the application layer. The application framework layer includes some predefined functions. As shown in FIGS. 7A-1 and 7A-2 , the framework layer may include a sensor manager 707, a posture recognition 708, a display manager 709, and a window manager service (WMS) 710. Optionally, the framework layer may further include an activity manager service (AMS), a content provider, a view system, a telephone manager, a resource manager, a notification manager, etc. (not shown in the accompanying drawings).

[0143] A window manager is configured to manage window programs and may perform tasks such as getting the size of the display, determining whether there is a status bar, performing screen locking, and taking screenshots.

[0144] The hardware abstraction layer (HAL) includes a sensor service 706. The sensor service 706 can be configured to report the processing results of the sensor data processing module 705 in the kernel layer to a sensor manager 707 in the framework layer.

[0145] The kernel layer is a layer between the hardware and the software. The kernel layer may include a sensor data processing module 705. The sensor data processing module 705 may be configured to acquire data reported by one or more sensors in the hardware layer, perform processing, and report the processing results to a sensor service 706.

[0146] The hardware layer may include an acceleration sensor 701, a gyroscope sensor 702, an acceleration sensor 703, and a gyroscope sensor 704, etc. The acceleration sensor 701 and the gyroscope sensor 702 may be disposed on screen A of the electronic device 100, and the acceleration sensor 703 and the gyroscope sensor 704 may be disposed on screen B of the electronic device 100. The acceleration sensor 701 may be configured to measure acceleration data of screen A and report the acceleration data to the sensor data processing module 705. The acceleration sensor 703 may be configured to measure acceleration data of screen B and report the acceleration data to the sensor data processing module 705. The gyroscope sensor 702 may be configured to measure gyroscope data of screen A and report the gyroscope data to the sensor data processing module 705. The gyroscope sensor 704 may be configured to measure gyroscope data of screen B and report the gyroscope data to the sensor data processing module 705.

[0147] When a user performs an input operation (e.g., an operation to fold the screen) on the electronic device 100, the acceleration sensor 701, the gyroscope sensor 702, the acceleration sensor 703, and the gyroscope sensor 704 in the hardware layer may report sensor data measured by each of the acceleration sensor 701, the gyroscope sensor 702, the acceleration sensor 703, and the gyroscope sensor 704 to the sensor data processing module 705 in the kernel layer. The sensor data processing module 705 calculates a direction vector of the orientation of the screen A based on the sensor data reported by the multiple sensors in the hardware layer.

[0148] In some embodiments, electronic device 100 may have multiple physical screens. For example, as shown in FIG. 3(d), electronic device 100 includes a foldable screen and a screen C. The foldable screen folds into screen A and screen B, and screen C is on the back of screen A.

[0149] As shown in FIG. 7B , in a multi-screen display scenario, the framework layer in the software structure of electronic device 100 may include display device information corresponding to each physical screen. For example, the foldable screen corresponds to display device module 1. Display device module 1 is configured to describe the physical screen information of the foldable screen. The physical screen information includes, for example, resolution and dots per inch (DPI). Screen C corresponds to display device module 2. Display device module 2 is configured to describe the physical screen information of screen C. Each physical screen of electronic device 100 further corresponds to a logical display module. The logical module is configured to describe the logical display information of the physical screen. For example, the foldable screen of electronic device 100 corresponds to logical display module 1, and screen C corresponds to logical display module 2. Each logical display module may derive an active display module and a display content module. For example, logical display module 1 may derive active display module 1 and display content module 1, and logical display module 2 may derive active display module 2 and display content module 2. An activity manager service (AMS) and a window manager service (WMS) may manage the display logic of all upper-layer applications based on the aforementioned activity display modules and display content modules. Electronic device 100 may start and display different activities on different logical display modules. For example, if a foreground application displayed on the foldable screen enables automatic countdown capture, electronic device 100 may synchronously enable screen C on the back of the foldable screen to display a countdown.

[0150] In some embodiments, a framework layer on electronic device 100 may implement an architecture in which a physical display device is separated from a logical display layer. The logical display layer includes specific display content on a screen, and the physical display device (e.g., a foldable screen) is configured to display all or a portion of the display content in the logical display layer. A mapping relationship between the display content and the display area on the physical display device may be set in the framework layer of electronic device 100. For example, by using an architecture in which the physical display device is separated from the logical display layer, electronic device 100 may separately display different interfaces of the same application on screen A and screen B when the foldable screen is in a half-folded configuration.

[0151] As shown in FIG. 7C, in (a) of FIG. 7C, the size of the logical display layer is the same as the size of the physical display device. In (b) of FIG. 7C, the size of the logical display layer is larger than the size of the physical display device. In (c) of FIG. 7C, the size of the logical display layer is smaller than the size of the physical display device. In (d) of FIG. 7C, electronic device 100 may display a portion of the display content in the logical display layer in all areas of the physical display device (e.g., a foldable screen). In (e) of FIG. 7C, electronic device 100 may display all of the content in the logical display layer in some of these areas of the physical display device (e.g., a foldable screen).

[0152] With reference to application scenarios, the following specifically describes a display method for a foldable screen according to an embodiment of the present application.

[0153] When the foldable screen of electronic device 100 is in a fully folded configuration, the included angle (i.e., folding angle) α between screen A and screen B of electronic device 100 is

[0154] In a possible implementation, the included angle α between screen A and screen B of the electronic device 100 is

number

[0155] In some application scenarios, when the foldable screen of electronic device 100 is in a half-folded state, if a foreground application (e.g., a camera application or a WeChat application) running on electronic device 100 that supports window display adaptation launches the camera, electronic device 100 may display the application interface of the foreground application on screen A or screen B of the foldable screen. In this way, a user can conveniently take photos, make video calls, or live broadcasts, etc., without having to hold electronic device 100 steadily with both hands.

[0156] 8A , the foldable screen of electronic device 100 is in the unfolded configuration, and the front-facing camera 801 of electronic device 100 is oriented in the same direction as the display direction of the foldable screen. Electronic device 100 may display home screen 810 full-screen on the foldable screen. Home screen 810 displays a page on which application icons are arranged, and the page includes multiple application icons (e.g., a weather application icon, a stocks application icon, a calculator application icon, a settings application icon, an email application icon, an Alipay application icon, a Facebook® application icon, a WeChat application icon, a gallery application icon 813, a music application icon 814, a video application icon, and a browser application icon). A page indicator is further displayed below the multiple application icons to indicate the positional relationship between the currently displayed page and another page. Multiple tray icons (e.g., a phone application icon, a message application icon, a contacts application icon, and a camera application icon 812) are located below the page indicator. When pages are switched, the tray icons remain displayed. In some embodiments, a page may alternatively include multiple application icons and a page indicator. The page indicator may not be part of the page but may exist independently, and a tray icon is also optional. This is not limited to this embodiment of the present application. A status bar 811 may further be displayed at the top of the home screen 810. The status bar 811 may include one or more signal strength indicators for a mobile communication signal (also referred to as a cellular signal), a battery status indicator, a time indicator, etc.

[0157] Electronic device 100 may receive a user input action (e.g., a tap) on camera application icon 812. In response to the input action, electronic device 100 may enable the camera to display camera application interface 820 shown in FIG.

[0158] As shown in FIG. 8B , the camera application interface 820 may display a capture image echo control 821, a capture control 822, a camera switch control 823, an image captured by the camera 824, a flash control 825, a settings control 826, and one or more capture mode controls (e.g., a “wide aperture mode” control 827A, a “night mode” control 827B, a “normal capture mode” control 827C, a “portrait mode” control 827D, and a “video mode” control 827E). The capture image echo control 821 may be configured to display a captured image. The capture control 822 may be configured to trigger saving of an image captured by the camera. The camera switch control 823 may be configured to switch the camera for capture. The flash control 825 may be configured to turn the flash on or off. The settings control 826 may be configured to set capture functions. The capture mode controls may be used to trigger activation of image processing procedures corresponding to the capture mode. For example, the “night mode” control 827B may be configured to trigger increasing the brightness and color richness, etc., in the captured image. The "Portrait Mode" control 827D may be configured to trigger a blur of the background of people in the captured image.

[0159] When electronic device 100 detects that the foldable screen has changed from the unfolded configuration to the half-folded configuration and the camera is enabled on the camera application interface, electronic device 100 may display the camera application interface on screen A or screen B. Electronic device 100 may display the camera application interface on a preset half-screen of screen A and screen B according to a preset display rule. For example, electronic device 100 may receive a user input, and it is preset that when the foldable screen is in the half-folded configuration, the application interface of the foreground application for activating the camera is displayed on screen A.

[0160] For example, as shown in FIG. 8C , when electronic device 100 detects that the foldable screen is changing from the unfolded configuration to the half-folded configuration, electronic device 100 may display camera application interface 830 on screen A and turn off screen B. Camera application interface 830 may include a capture image echo control 831, a capture control 832, a camera switch control 833, an image captured by the camera 834, a flash control 835, a settings control 836, and one or more capture mode controls (e.g., a "wide aperture mode" control 837A, a "night mode" control 837B, a "normal capture mode" control 837C, a "portrait mode" control 837D, and a "video mode" control 837E). The interface elements in camera application interface 830 are the same as the interface elements in camera application interface 820 shown in FIG. 8B . Therefore, for a description of camera application interface 830, please refer to the main description of camera application interface 820 in the embodiment shown in FIG. 8B . Details will not be described again here. The display ratio of camera application interface 830 is different from the display ratio of camera application interface 820 , and the display ratio of interface elements in camera application interface 830 may also be different from the display ratio of interface elements in camera application interface 820 .

[0161] In a possible implementation, when the foldable screen of electronic device 100 is in a half-folded configuration, electronic device 100 may further detect an included angle β1 between a plane on which screen A is located and a horizontal plane. If the plane on which screen A is located is approximately parallel to the horizontal plane (i.e., if the included angle β1 is less than a preset angle threshold P3 (e.g., 10 degrees)), electronic device 100 may switch the camera application interface displayed on screen A to be displayed on screen B.

number

[0162] 8D , the foldable screen of electronic device 100 is in a half-folded configuration, and electronic device 100 may use a camera application to activate rear camera 802 on the back of screen A to capture the sky. The plane on which screen A is located is parallel to the horizontal plane (e.g., the included angle β1 between the plane on which screen A is located and the horizontal plane is 5 degrees), and the plane on which screen B is located is approximately perpendicular to the horizontal plane (e.g., the included angle β2 between the plane on which screen B is located and the horizontal plane is 93 degrees). Electronic device 100 may display camera application interface 840 on screen B and turn off screen A. Camera application interface 840 may display captured image echo control 841, shooting control 842, camera switch control 843, image captured by camera 844, flash control (not shown in FIG. 8D ), settings control 846, and one or more shooting mode controls (e.g., “wide aperture mode” control 847A, “night mode” control 847B, “normal shooting mode” control 847C, “portrait mode” control 847D, and “video mode” control 847E). The interface elements in camera application interface 840 are the same as the interface elements in camera application interface 820 shown in FIG. 8B . Therefore, for a description of camera application interface 840, please refer to the main description of camera application interface 820 in the embodiment shown in FIG. 8B . The details will not be described again here. The display ratio of camera application interface 830 is different from that of camera application interface 820, and the display ratio of interface elements in camera application interface 830 may also be different from that of interface elements in camera application interface 820.

[0163] In a possible implementation, when the foldable screen of electronic device 100 is in a half-folded configuration, electronic device 100 may further detect an included angle β1 between a plane on which screen A is located and a horizontal plane. If the plane on which screen A is located is approximately parallel to the horizontal plane (i.e., the included angle β1 is between a preset angle threshold P3 and a preset angle threshold P4, for example, the included angle β1 may be 93 degrees), electronic device 100 may switch the camera application interface displayed on screen B to be displayed on screen A.

number

[0164] In some application scenarios, there may be a screen behind the foldable screen of electronic device 100, for example, screen C shown in (d) of FIG. 3 . Screen C is on the same side as the rear camera. When the foldable screen is in a half-folded form or a fully folded form, screen C may face screen A. When electronic device 100 is in a half-folded form and a foreground application (e.g., a camera application or a WeChat application) activates the camera to perform countdown photography, electronic device 100 may display a photography countdown on screen C. In this way, when the owner leaves the electronic device and performs automatic countdown photography with another person, the countdown may be displayed on screen C. This is convenient for the user to assume a photography posture, thereby improving the user experience.

[0165] For example, as shown in Figure 9A, electronic device 100 is in a half-folded configuration. Electronic device 100 activates the camera by using a camera application, displays a camera application interface 830 on screen A, and turns off screen B. Camera application interface 830 includes an image 834 captured by the camera. For a full description of camera application interface 830, please refer to the embodiment shown in Figure 9A. Details will not be described again here.

[0166] The electronic device 100 may receive a user input operation (e.g., a tap) on the settings control 836. In response to the input operation, the electronic device 100 may display the settings interface 910 shown in FIG.

[0167] 9B , the setting interface 910 may include one or more setting entries (e.g., a resolution setting entry, a geographic location setting entry, a watermark setting entry, a mute shooting setting entry, a timed shooting setting entry 911, and a sound-controlled shooting setting entry). Currently, the timed shooting function of the electronic device 100 is disabled, and the timed shooting setting entry may be used to receive a user's input operation, enable the timed shooting function, and set a period.

[0168] The electronic device 100 may receive a user input operation (e.g., a tap) on the timed shooting setting entry 911. In response to the input operation, the electronic device 100 may display a timed shooting setting window 920 shown in FIG. 9C on the screen A.

[0169] 9C , the timing capture setting window 920 may display one or more setting options (e.g., a disable option, a 3-second timing option 921, a 5-second timing option, and a 10-second timing option). The electronic device 100 may receive a user input operation (e.g., a tap) on the 3-second timing option 921. In response to the input operation, the electronic device 100 may enable the timing capture function and set the duration to 3 seconds.

[0170] 9D, after setting the duration of the timed capture function to 3 seconds, electronic device 100 may receive a user input operation (e.g., a tap) on capture control 832 in camera application interface 830. In response to the input operation (e.g., a tap), electronic device 100 may display capture countdown prompt 931, shown in FIG. 9E, on screen A and countdown prompt 932, shown in FIG. 9F, on screen C behind screen A.

[0171] 9E , the capture countdown prompt 931 may be used to prompt the user of the remaining time for the electronic device 100 to store images captured by the camera. For example, the current remaining time is 3 seconds. If the remaining time is 0 seconds, the electronic device 100 may locally store the images captured by the camera as captured images and display thumbnails of the images in the captured image echo control 831. The user may further open a gallery application on the electronic device 100 to view images captured by the electronic device 100.

[0172] 9F, in response to a user's input operation on the capture control 832 in FIG. 9D, the electronic device 100 may display a capture countdown prompt 932 on screen C. The capture countdown prompt 932 may be used to prompt the user the remaining time for the electronic device 100 to store images captured by the camera.

[0173] In a possible implementation, when the foldable screen of electronic device 100 is in a half-folded configuration and a foreground application (e.g., a camera application or a WeChat application) of electronic device 100 enables a countdown photo-taking function, electronic device 100 may determine whether the foreground application is activating front-facing camera 801 or rear-facing camera 802. If the foreground application is activating front-facing camera 801, electronic device 100 may display a photo-taking countdown on screen A in response to a user's photo-taking operation (e.g., a user's input operation on photo-taking control 832 in FIG. 9D ). If the foreground application is activating rear-facing camera 802, electronic device 100 may display a photo-taking countdown on both screen A and screen C. In this way, when a user activates the front-facing camera to take a selfie, the photo-taking countdown may be displayed only on screen A to prevent others from knowing that the user is taking a selfie. This protects user privacy.

[0174] In a possible implementation, the foldable screen of electronic device 100 is in a half-folded configuration. When a foreground application of electronic device 100 activates rear camera 802 to perform a countdown photo shoot, electronic device 100 may display a photo shoot countdown prompt and an image captured by rear camera 802 on screen A and screen C. In this way, the person whose back is being photographed can see the countdown numbers and prepare a pose and facial expression before the photo shoot.

[0175] For example, as shown in FIG. 9G, electronic device 100 may display on screen C a picture countdown prompt 933 and an image 934 captured by rear camera 802.

[0176] In some application scenarios, when the foldable screen of electronic device 100 is in the unfolded configuration, electronic device 100 may display the application interface of a foreground application (e.g., a gallery application). After the foldable screen of electronic device 100 changes to the half-folded configuration, electronic device 100 may launch an associated application (e.g., a camera application) or a shortcut application (e.g., a music application) of the foreground application, display the application interface of the foreground application on one half-screen of screen A and screen B, and display the associated application or shortcut application on the other half-screen of screen A and screen B. For example, electronic device 100 may display the application interface of the foreground application on screen A and display the application interface of the associated application or shortcut application on screen B. A user may pre-set an associated application for a foreground application on electronic device 100 and may also pre-set a shortcut application. For example, a user may pre-set an associated application as a camera application and a shortcut application as a music application for a gallery application on electronic device 100. In this manner, when the electronic device 100 is in the semi-folded configuration, multiple application tasks may be automatically launched, allowing the user to process multiple application tasks simultaneously.

[0177] In a possible implementation, a foreground application running on electronic device 100 has only one associated application. When electronic device 100 detects that the foldable screen is in a half-folded configuration, electronic device 100 may display the foreground application on screen A and the application interface of the associated application on screen B. Alternatively, electronic device 100 displays the foreground application on screen B and the application interface of the associated application on screen A.

[0178] For example, as shown in FIG. 10A , electronic device 100 is in an unfolded configuration and displays home screen 810. For a full description of home screen 810, please refer to the embodiment shown in FIG. 8A . The details will not be described again here. Electronic device 100 may receive a user input operation (e.g., a tap) on gallery application icon 813. In response to the input operation, electronic device 100 may display gallery application interface 1010 shown in FIG. 10B .

[0179] As shown in FIG. 10B, the gallery application interface 1010 may display one or more albums (e.g., an all photos album, an all videos album, a camera album, a screenshots album, a recently deleted album, a WeChat album, a Weibo album, and other albums).

[0180] An associated application of the gallery application may be a camera application. When electronic device 100 detects that the foldable screen is changing from the unfolded configuration shown in FIG. 10B to the semi-folded configuration, it may display the application interface of the gallery application on screen A and the application interface of the camera application on screen B.

[0181] 10C, when electronic device 100 detects that the foldable screen is changing from the unfolded configuration shown in FIG. 10B to the semi-folded configuration, electronic device 100 may display gallery application interface 1020 on screen A and camera application interface on screen B. Compared to gallery application interface 1010 shown in FIG. 10B, gallery application interface 1020 displays less content and has a lower display ratio.

[0182] In a possible implementation, when electronic device 100 detects that the foldable screen is changing from the unfolded configuration to the semi-folded configuration, and an associated application of the foreground application exists and a camera application exists within the foreground application and the associated application, electronic device 100 may determine whether the plane on which screen A is located is approximately parallel to the horizontal plane (i.e., the included angle β1 between the plane on which screen A is located and the horizontal plane is less than a preset angle threshold P3 (e.g., 10 degrees)). If the plane on which screen A is located is approximately parallel to the horizontal plane, electronic device 100 may display the application interface of the camera application on screen B and the application interface of another application within the foreground application and the associated application on screen A. If the plane on which screen A is located is not approximately parallel to the horizontal plane (i.e., the included angle β1 between the plane on which screen A is located and the horizontal plane is greater than or equal to a predetermined angle threshold P3 (e.g., 10 degrees)), electronic device 100 may display the application interface of the camera application on screen A and the application interface of another application within the foreground application and related applications on screen B.

[0183] 10D, the related application of the gallery application is a camera application. When electronic device 100 detects that the foldable screen is changing from the unfolded configuration to the half-folded configuration and the plane on which screen A is located is not approximately parallel to the horizontal plane (i.e., the included angle β1 between the plane on which screen A is located and the horizontal plane is greater than or equal to a preset angle threshold P3 (e.g., 10 degrees)), electronic device 100 may display camera application interface 1040 on screen A and gallery application interface 1050 on screen B. Compared with gallery application interface 1010 shown in FIG. 10B, gallery application interface 1050 has less display content and a lower display ratio.

[0184] In a possible implementation, a foreground application running on electronic device 100 may have multiple associated applications. When the foldable screen of electronic device 100 is in a half-folded configuration, electronic device 100 may display an application interface of a foreground application (e.g., a gallery application) on screen A and display icons of multiple associated applications (e.g., a camera application, a music application, a video application, and a WeChat application) on screen B. Then, when electronic device 100 receives a user input to select a designated associated application from the multiple associated applications, it may display the application interface of the foreground application (e.g., a camera application) and the application interface of the designated associated application on screen A and screen B, respectively.

[0185] For example, as shown in Figure 11A, electronic device 100 is in an unfolded configuration and displays gallery application interface 1110. For a full description of gallery application interface 1110, please refer to the embodiment shown in Figure 10B, and the details will not be described again here.

[0186] The associated applications of the gallery application include a camera application, a music application, a video application, a WeChat application, etc. When electronic device 100 detects that the foldable screen is changing from the unfolded configuration shown in FIG. 11A to the semi-folded configuration, it may display the application interface of the gallery application on screen A and display icons of multiple associated applications of the gallery application on screen B.

[0187] 11B, when electronic device 100 detects that the foldable screen is changing from the unfolded configuration shown in FIG. 11A to the semi-folded configuration, electronic device 100 may display gallery application interface 1120 on screen A and related application selection interface 1130 on screen B. Compared to gallery application interface 1110 shown in FIG. 11A, gallery application interface 1120 has less display content and a lower display ratio. Related application selection interface 1130 displays icons of multiple related applications (e.g., a camera application icon 1131, a music application icon, a video application icon, and a WeChat application icon). Related application selection interface 1130 may further display an add control 1132. The add control 1132 may be used to add a new related application to the gallery application.

[0202] The following describes a display method for a foldable screen according to one embodiment of the present application.

[0203] 14 is a schematic flowchart of a display method for a foldable screen according to one embodiment of the present application. The method is applied to an electronic device including a foldable screen. The foldable screen may be folded to form at least two screens, and the at least two screens include a first screen and a second screen. As shown in FIG. 14, the method may include the following steps:

[0204] S1401: When the foldable screen is in the unfolded configuration, the electronic device displays a first interface of a first application on the foldable screen in full screen, the first interface including an image captured by a camera, the image captured by the camera being an image captured before a capture confirmation signal is received.

[0205] When the foldable screen is in the unfolded configuration, the included angle between the first screen and the second screen is greater than a first angle threshold, and when the foldable screen is in the half-folded configuration, the included angle between the first screen and the second screen is between the first angle threshold and a second angle threshold. The first angle threshold is greater than the second angle threshold. Specifically, the foldable screen may be an inward-facing foldable screen or an outward-facing foldable screen.

[0206] For example, the first angle threshold is P2 and the second angle threshold is P1. When the foldable screen of the electronic device 100 is in a fully folded configuration, the included angle (i.e., folding angle) α between the screen A and the screen B of the electronic device 100 is

number

number

[0207] In a possible implementation, if the period during which the included angle between the first screen and the second screen remains between the first angle threshold and the second angle threshold is greater than a first time threshold (e.g., 0.6 seconds), the electronic device detects that the foldable screen is changing to the half-folded configuration. In this way, the electronic device can accurately identify that the user wants the foldable screen to enter the half-folded configuration, thereby improving the accuracy of the determination.

[0208] S1402: When detecting that the foldable screen is changing from the unfolded configuration to the half-folded configuration, the electronic device displays a second interface on the first screen.

[0209] For example, the first screen may be screen A in the above embodiment, and the second screen may be screen B in the above embodiment. The first application may be a camera application. When the first interface is displayed, the first application launches a camera. The first interface may be camera application interface 820 shown in FIG. 8B. The second interface may be camera application interface 830 shown in FIG. 8C. The display content (also referred to as interface elements) in camera application interface 830 is the same as the display content (also referred to as interface elements) in camera application interface 820 shown in FIG. 8B.

[0210] According to this embodiment of the present application, when the foldable screen of electronic device 100 is in a half-folded state, if a foreground application (e.g., a camera application or a WeChat application) running on electronic device 100 that supports windowed display adaptation launches the camera, electronic device 100 may display the application interface of the foreground application on screen A or screen B of the foldable screen. In this way, a user can conveniently take photos, make video calls, or perform live broadcasts, etc., without having to hold electronic device 100 steadily with both hands.

[0211] In a possible implementation, when the included angle between the plane on which the first screen is located and the horizontal plane is less than a third angle threshold, the electronic device displays the second interface on the second screen. For example, the third angle threshold may be P3,

[0212] In a possible implementation, the electronic device further includes a third screen, and the third screen faces the first screen when the foldable screen is folded. The method further includes, after the electronic device enables the time-lapse photography function, receiving a first user input via the second interface. In response to the first input, the electronic device displays a countdown prompt on the first screen and the third screen. The countdown prompt is used to prompt the user of the remaining time for capturing an image captured by the camera.

[0213] The third screen may be screen C in the embodiment shown in FIG. 9F. When the electronic device is in the half-folded form and a first application (e.g., a camera application or a WeChat application) activates the camera to perform countdown photography, the electronic device may display the photography countdown on screen C. In this way, when the owner leaves the electronic device and performs automatic countdown photography with another person, the countdown may be displayed on screen C. This is convenient for the user to assume a photography posture, thereby improving the user experience. For specific details, please refer to the embodiments shown in FIGS. 9A to 9F. Details will not be described again here.

[0214] In a possible implementation, in response to the first input, the electronic device displays an image captured by the camera on a third screen. For example, as shown in Fig. 9G, the electronic device displays a photo countdown prompt 933 and an image 934 captured by the rear camera 802 on screen C. For specific details, please refer to the embodiment shown in Fig. 9G. Details will not be described again here.

[0215] In a possible implementation, the first application is associated with a second application. When detecting that the foldable screen is changing from the unfolded form to the half-folded form, the electronic device displays a third interface of the second application on the second screen. The first application may be a camera application, and the second application may be a gallery application. The second interface may be the camera application interface 1040 shown in FIG. 10D, and the third interface may be the gallery application interface 1050 shown in FIG. 10D. For specific details, please refer to the embodiments shown in FIGS. 10A to 10D. Details will not be described again here.

[0216] In a possible implementation, the first application corresponds to a plurality of associated applications. When detecting that the foldable screen is changing from the unfolded form to the semi-folded form, the electronic device displays options of the plurality of associated applications on the second screen. The electronic device receives a second input from the user for an option corresponding to the second application. In response to the second input, the electronic device displays a third interface of the second application on the second screen. For specific details, please refer to the embodiments shown in Figures 11A to 11C. Details will not be described again here.

[0217] In a possible implementation, the electronic device displays the switch control on the first screen or the second screen. The electronic device receives a third input from the user on the switch control. In response to the third input, the electronic device displays a third interface on the first screen and a second interface on the second screen. For example, the switch control may be the switch control 1241 shown in FIG. 12C. For specific details, please refer to the embodiments shown in FIGS. 12A to 12D. Details will not be described again here.

[0218] In a possible implementation, when the foldable screen changes from a half-folded configuration to a fully folded configuration, the electronic device may turn off the first screen and the second screen.

[0219] In some embodiments, when the foldable screen is in the unfolded configuration, the electronic device displays a first interface of a first application full-screen on the foldable screen. The first interface includes an image captured by a camera and one or more operation controls. When the electronic device detects that the foldable screen is changing from the unfolded configuration to the semi-folded configuration, the electronic device displays a fourth interface on the first screen and a fifth interface on the second screen. The fourth interface includes an image captured by the camera, and the fifth interface includes one or more operation controls. For example, the first interface may be the camera application interface 1310 shown in FIG. 13A , the fourth interface may be the camera application interface 1320 shown in FIG. 13B or FIG. 13C , and the fifth interface may be the camera application interface 1330 shown in FIG. 13B or the camera application interface 1340 shown in FIG. 13C . For specific details, please refer to the embodiments shown in FIGS. 13A to 13C . The details will not be explained again here.
