Description

Technical Field

[0001] The present application relates to the field of terminal technology, and in particular to an interface display method and device. Background Art

[0002] With the popularization and development of the Internet, people's functional requirements for electronic devices are becoming more and more diversified. For example, in order to improve users' demand for multi-service use, foldable screen mobile phones have gradually come into the user's field of vision. Users can use multiple display screens in foldable screen mobile phones to perform multiple services. For example, a foldable screen mobile phone is used as an external foldable mobile phone for schematic illustration. When the foldable screen mobile phone is in the unfolded state, the user can use display screen A for interface display; when the foldable screen mobile phone is in the folded state, the user can use display area B and / or display area C to display content. Among them, display area B and display area C are both composed of a part of the display area in display screen A.

[0003] However, there are certain limitations to the usage of the above-mentioned foldable screen mobile phones. Summary of the Invention

[0004] An embodiment of the present application provides a display method and device, which are applied to the field of terminal technology, so that a folding screen device can mirror the application interface displayed in the window of display area B to display area C, and the application interfaces in display area B and display area C can be refreshed synchronously to improve the limitations of using folding screen mobile phones.

[0005] In a first aspect, an embodiment of the present application provides an interface display method, which is applied to a folding screen device, wherein the folding screen device includes: a physical display screen, wherein the physical display screen includes: a first display area and a second display area, and when the folding screen device is in a folded state, the first display area and the second display area are arranged opposite to each other, and the method includes: creating a virtual screen, wherein the virtual screen corresponds to the second display area; the first display area displays a first interface, and the first interface includes: a first full-screen window corresponding to a first application and a first floating window corresponding to a second application, wherein the folding screen device is in a folded state, and the first floating window includes a first application interface corresponding to the second application; in response to a first operation on the second display area, the first full-screen window corresponding to the second application is displayed in the first display area. Two floating windows are provided, and the display area of ​​the virtual screen is set as the second display area, and the first application interface is displayed in the second display area through the virtual screen, and the size of the second floating window is smaller than the size of the first floating window; in response to the second operation on the second floating window, the first floating window is displayed in the first display area, and the first application interface is displayed in the second display area; in response to the third operation on the first floating window, a third floating window corresponding to the second application is displayed in the first display area, and the second application interface is displayed in the second display area, wherein the size of the third floating window is larger than the size of the second floating window, and the third floating window includes the second application interface corresponding to the second application, and the second application interface is different from the first application interface.

[0006] The first display area may be the display area B described in the embodiment of the present application, and the second display area may be the display area C described in the embodiment of the present application.

[0007] The first interface may be the interface shown in FIG5C , the first application may be a note application, and the first full-screen window corresponding to the first application may be a note application interface displayed in full screen.

[0008] The second application may be a payment application, and the first floating window corresponding to the second application may be floating window 501 in FIG. 5C . The first application interface corresponding to the second application may be the payment interface in the payment application, such as the application interface in floating window 501, i.e., the payment interface is displayed in floating window 501, and the first application interface does not include the control controls in floating window 501. It is understood that the first application interface is not the interface in the first application.

[0009] The first operation may be the operation of double-clicking the display area C as described in FIG5C , or may be other operations for entering the collaborative display, see Figure 5-2 to Figure 6-1 Description in .

[0010] The second floating window may be the mini window 506 in FIG. 5E .

[0011] The second operation may be a click operation on the mini window 506 .

[0012] As shown in Figure 6A, the third operation may be an operation of sliding up floating window 601. The third floating window may be floating window 601 in Figure 6C, and the second application interface corresponding to the second application may be the application interface displayed in floating window 601, and the second application interface does not include the control controls in floating window 601.

[0013] In this way, the folding screen device can not only display the content in the window of display area B in the display area C, but also in response to the trigger operation performed by the user on the display area C, the application interface in the floating window can be updated synchronously with the application interface in the display area C, so that the user can view the updated application interface in the display area C in real time.

[0014] In one possible implementation, the first display area is obtained by controlling the display interface through the first logical screen, and setting the display area of ​​the virtual screen to the second display area includes: setting the display area of ​​the physical display screen to the entire display area, so that the content in the first logical screen and the content in the virtual screen are both displayed from the starting position of the entire display area, and the starting position of the second display area is the same as the starting position of the entire display area.

[0015] The first logical screen may be the logical screen 1 described in the embodiment of the present application, and the starting position of the second display area may be Figure 14 The starting position 2 described in the above description can be the starting position of the entire display area. Figure 14 The starting position described in 1.

[0016] In this way, the folding screen device can set the starting position of the first display area and the starting position of the second display area at the starting position of all display areas by setting the entire display area. At this time, the first display area and the second display area can be displayed overlappingly.

[0017] In a possible implementation, the display layer of the first logical screen is moved from a starting position of the entire display area to a first position, where the first position is the starting position of the first display area.

[0018] In this way, the folding screen device can move the display layer of the first logical screen to the first position, so that the first logical screen can display the interface in the first display area, and the virtual screen can display the interface in the second display area, thereby reducing the overlapping display between the first display area and the second display area.

[0019] In one possible implementation, after setting the display area of ​​the virtual screen to the second display area, the method further includes: setting the virtual screen to the default display screen, and before setting the virtual screen to the default display screen, the virtual screen corresponds to the first layer, and the first layer is not allowed to be displayed on the physical display screen.

[0020] The first layer corresponding to the virtual screen can be understood as the layer stack of the virtual screen itself.

[0021] It is understandable that the default display allows display on the physical display, so the folding screen device can display the content in the virtual screen on the physical display by setting the virtual screen as the default display.

[0022] In one possible implementation, the method also includes: when receiving a second status message, restoring the display layer of the first logical screen from the first position to the starting position of the entire display area, and restoring the layer of the virtual screen to the first layer, wherein the second status message is generated when the folding screen device detects the operation of unfolding the folding screen device, or, when receiving a third status message, restoring the layer of the virtual screen to the first layer, and restoring the display area of ​​the physical display screen to the first display area, wherein the third status message is generated when the folding screen device detects a preset operation, and the preset operation includes one or more of the following: the operation of switching the second floating window to a floating ball, the operation of displaying the content in the second floating window in full screen, or the operation of closing the second floating window.

[0023] The second status message may be the status change message 2 described in the embodiment of the present application. Thus, upon detecting that the foldable screen device has been unfolded, the foldable screen device can restore the display position of the first logical screen and the original first layer of the virtual screen, allowing the content in the first display area to continue to the physical display screen, thereby reducing interruptions in the displayed content.

[0024] The third status message may be the status change message 3 described in the embodiment of the present application, and the preset operation may be the preset exit operation described in the embodiment of the present application. Thus, upon detecting the preset operation, the foldable screen device can restore the display position of the first logical screen and set the display area of ​​the physical display screen to the first display area, thereby ensuring normal display of the content in the first display area and not displaying any content in the second display area.

[0025] In one possible implementation, after responding to the first operation on the second display area, the method also includes: when receiving a first status message related to the first operation, obtaining the task task in the first floating window; mirroring the layer in the task to obtain a second layer; and mounting the second layer to the virtual screen.

[0026] The first status message may be the status change message 1 described in the embodiment of the present application, and the second layer may be the layer 1 described in the embodiment of the present application.

[0027] In this way, the folding screen device can achieve the coordinated display of the first floating window and the content in the second display area by mirroring the task in the first floating window and mounting the mirrored layer to the virtual screen.

[0028] In one possible implementation, the outer border of the second floating window is in a first state, and the outer borders of the first floating window and the third floating window are in a second state, wherein the thickness of the outer border line in the first state is greater than the thickness of the outer border line in the second state, and / or the color of the outer border in the first state is different from that of the outer border in the second state.

[0029] In this way, the folding screen device can use the first state to indicate that the content in the floating window has been mounted on the external screen, and use the second state to indicate that the content in the floating window is not mounted on the external screen, so that the user can determine the collaborative display situation without checking the external screen, thereby improving the user experience of using the collaborative display function.

[0030] In one possible implementation, the method also includes: in response to a fourth operation on the first display area, displaying a fourth floating window corresponding to the third application in the first display area, the fourth floating window including a third application interface corresponding to the third application; in response to a fifth operation on the fourth floating window, displaying a fifth floating window corresponding to the third application in the first display area, and displaying a first prompt message in the second display area, wherein the size of the fifth floating window is smaller than the size of the fourth floating window, and the first prompt message is used to prompt that the third application interface does not support collaborative display to the second display area; or, in response to the fifth operation, displaying the fifth floating window and the first prompt message in the first display area.

[0031] The fourth operation may be to open another floating window. The fourth floating window may be Figure 7 The floating window 701 in A.

[0032] The third application may be a financial application, and the third application interface may be an application interface displayed in the floating window 701 , such as a transfer interface.

[0033] The first prompt information may be prompt information 801 .

[0034] In this way, the folding screen device can determine whether to enter collaborative display based on the attributes of the interface, and prompt the user through the first display area or the second display area when it is determined that the collaborative display cannot be entered, so as to improve the user experience of using the collaborative display function.

[0035] In one possible implementation, after displaying the first application interface in the second display area, the method further includes: displaying a second prompt message in the first display area, the second prompt message being used to prompt that the folding screen device is abnormal and whether to end displaying the first application interface in the second display area; and / or, after responding to the first operation on the second display area, the method further includes: displaying a third prompt message in the first display area, the third prompt message being used to prompt that the folding screen device is abnormal and whether to display the first application interface in the second display area.

[0036] The second prompt information may be the prompt information 1104 described in FIG. 11A , and the third prompt information may be the prompt information 1106 described in FIG. 11D .

[0037] In this way, the foldable screen device can promptly notify the user through prompt information when it detects that the device is in an abnormal state, so as to reduce the situation where the device power drops rapidly or the device freezes without the user's perception.

[0038] In one possible implementation, the folding screen device is in an abnormal state including: the folding screen device detects that the percentage of battery power is less than a first value, and / or the folding screen device detects that the device temperature is greater than a second value.

[0039] It is understandable that the collaborative display function has high power consumption and / or battery power requirements, so the folding screen device can determine that the folding screen device is abnormal when it detects that the device power is low and the device temperature is high.

[0040] In a possible implementation, after displaying the first application interface in the second display area, the method further includes:

[0041] In response to the operation of opening the notification center from the first display area, a fourth prompt message is displayed in the first display area, and the first application interface is displayed in the second display area. The fourth prompt message is used to prompt the folding screen device to display the first application interface in the second display area.

[0042] The fourth prompt information can be Figure 8 Prompt message 801 in A.

[0043] In this way, the foldable screen device can view the status of the foldable screen device from the notification center.

[0044] In a possible implementation, after displaying the first application interface in the second display area, the method further includes:

[0045] In response to the operation of unfolding the folding screen device, a second floating window is displayed on the physical display screen.

[0046] In this way, when the folding screen device detects that the device is unfolded, it can connect the content displayed in the first display area to the physical display screen to reduce interruptions in the displayed content.

[0047] In a possible implementation, after displaying the first application interface in the second display area, the method further includes:

[0048] In response to the sixth operation on the first display area, cancel displaying any content in the second display area, wherein the sixth operation includes one or more of the following: an operation of switching the second floating window to a floating ball, an operation of displaying the content in the second floating window in full screen, or an operation of closing the second floating window.

[0049] The sixth operation may be the preset exit operation described in the embodiment of the present application.

[0050] In this way, the folding screen device can promptly cancel the display of any content in the second display area when a preset exit operation is detected, so as to reduce power consumption waste.

[0051] In a possible implementation, the first operation on the second display area includes: multiple tapping operations on the second display area.

[0086] To facilitate a clear description of the technical solutions of the embodiments of the present application, some of the terms and technologies involved in the embodiments of the present application are briefly introduced below:

[0087] 1. Floating windows and mini windows

[0088] Both floating windows and mini windows are movable windows that float on top of other applications, allowing users to view different applications simultaneously. Both mini windows and floating windows are a form of application displayed in the foreground, and both have the window attribute "visible." Mini windows are a special form of floating windows, occupying a larger display area than mini windows.

[0089] A floating window can be an interactive window, and the way to control an application in a floating window is the same as the way to control an application in a full-screen window. For example, a floating window can respond to a trigger operation performed by the user to implement various functions such as interface switching, function activation or deactivation, etc.

[0090] A mini window can be another type of interactive window. For example, a mini window is typically used to display an application interface. In response to a user clicking on a mini window, the electronic device can display a corresponding floating window. Alternatively, in response to a user double-clicking on a mini window, the electronic device can display the application interface in the mini window in full screen. Furthermore, a mini window cannot respond to user trigger operations on the application in the mini window.

[0091] It is understood that an application can switch between a floating window and a mini window. For example, in response to a user dragging a floating window to any corner of the electronic device, the electronic device can shrink the floating window to a mini window. In response to a user clicking on the mini window, the electronic device can expand the mini window to a floating window. It is understood that the method for switching between a floating window and a mini window is not specifically limited in the embodiments of the present application.

[0092] 2. Folding screen devices

[0093] A foldable screen device is an electronic device that can be folded through hinges and flexible screens. The types of foldable screen devices can include: horizontally foldable screen devices (such as Figure 1 ), or a vertically folding folding screen device, etc. Among them, the horizontally folding folding screen mobile phone may include: an inner folding device (such as an inner folding mobile phone), and an outer folding device (such as an outer folding mobile phone), etc.

[0094] A foldable phone can contain two displays: an inner screen and an outer screen, with the inner screen folding inward. When the user folds the inner screen inward, the screen displayed on the outside becomes the outer screen, while the screen folded inward becomes the inner screen. This phone resembles a flip phone.

[0095] A foldable mobile phone may include a display screen, such as display screen A, which is foldable. After a user folds display screen A outward, a portion of the display area of ​​display screen A may constitute display area B, and a portion of the display area of ​​display screen A may constitute display area C. Display area B and display area C do not overlap.

[0096] The following takes the foldable screen mobile phone as an example to illustrate the display screen of the foldable mobile phone. Figure 1 A schematic diagram of a foldable screen mobile phone provided in an embodiment of the present application.

[0097] When the foldable screen mobile phone is in the unfolded state, the front (or front view) of the foldable screen mobile phone can be seen Figure 1 As shown in A, the back (or rear view) of the folding screen mobile phone can be seen Figure 1 B. The unfolded state can be understood as the state when the folding angle of the folding screen mobile phone is close to 180 degrees (such as 175 degrees, etc.), and the folding angle can be the angle generated when the display area B is folded.

[0098] When the folding screen mobile phone is in the unfolded state, the folding screen mobile phone can Figure 1 Display screen A shown in A is used for interface display.

[0099] Display screen A can be the screen of a foldable screen mobile phone in the unfolded state. Display screen A can also be called a full screen, etc. Display screen A is usually foldable. Display screen A can be composed of a display area 101, a folding area and a display area 102.

[0100] The folding area can be understood as the folding position when the folding screen phone is folded outward. When the folding screen phone is in the folded state, the folding area is generally located on the side of the folding screen phone. The dotted box corresponding to the folding area is not actually displayed Figure 1 A.

[0101] A camera 1 is provided at the upper right corner of the display screen A. The camera 1 may also be referred to as a front camera, and may collect image data facing the display screen A.

[0102] Figure 1The left area in B may be the back panel of the foldable screen phone, which may be equipped with a combination camera and a switch. The number of cameras in the combination camera may be three, for example. Any camera in the combination camera may also be called a rear camera, which can capture image data from the back of the foldable screen phone. The switch can be used to secure the foldable screen phone in the folded state and to unfold the foldable screen phone.

[0103] When the foldable screen mobile phone is in the folded state, the front (or front view) of the foldable screen mobile phone can be seen Figure 1 As shown in D, the back (or rear view) of the foldable screen mobile phone can be seen in Figure 1 C. The folded state can be understood as a state when the folding angle is close to 0 degrees (such as 5 degrees), and the folded state can also be called a closed state.

[0104] When the folding screen mobile phone is in the folded state, the folding screen mobile phone can Figure 1 The display area C shown in C, and / or, through Figure 1 The display area B shown in D is used for interface display.

[0105] It should be noted that both display area B and display area C can be the display area when the foldable screen mobile phone is in the folded state. Or it can be understood that when the foldable screen mobile phone is in the unfolded state, the interface cannot be displayed only through display area C and / or display area B.

[0106] The display area C may be formed by the display area 101 in the display screen A.

[0107] The display area B may be formed by the display area 102 in the display screen A. The display area B may be the main display area when the foldable screen mobile phone is in the folded state. The display area C includes the camera 1.

[0108] The size of display area B may be larger than that of display area C, or the size of display area B may be equal to the size of display area C, or the size of display area B may be equal to the size of display area C, which is not limited in the embodiments of the present application.

[0109] Understandable, Figure 1 The foldable screen mobile phone described in the specification is only an example. For example, the foldable screen mobile phone may not have a switch, or when the foldable screen mobile phone is in a folded state, the sizes of the two display areas may be the same, etc. The structure of the foldable screen mobile phone is not specifically limited in the embodiments of the present application.

[0110] Among possible implementations, a foldable phone could also have a semi-folded state, which can be understood as a partially folded state. In this case, the folding angle is between the unfolded and folded states, such as within a range of 90-135 degrees. In this semi-folded state, the phone can serve as a natural stand, allowing users to use part of the display area for functions like taking photos, making video calls, or watching videos without having to hold the phone.

[0111] It can be understood that the embodiment of the present application will use the folded state and the unfolded state as examples to schematically illustrate the interface display method. Figure 1 The front and back sides described in the specification are only used to distinguish the different sides of the foldable screen mobile phone and are not intended to limit the embodiments of the present application.

[0112] 3. Collaborative display

[0113] Collaborative display can be understood as an electronic device being able to display related content on different display screens, and as the user triggers an operation on one of the display screens, the content on the other display screen can be refreshed synchronously.

[0114] For example, when the electronic device is a foldable screen mobile phone, collaborative display can be understood as the foldable screen mobile phone mirroring the application interface in the display area B window to the display area C, so that the application interface displayed in the display area C is the same as the application interface in the display area B window, see Figure 5-1 to Figure 5-4 In response to the trigger operation performed by the user on the display area B window, the application interface displayed in the display area C can be refreshed synchronously with the application interface in the display area B window, see Figure 6-1 to Figure 6-2 Description in .

[0115] 4. Other terms

[0116] In the embodiments of this application, terms such as "first" and "second" are used to distinguish between identical or similar items with substantially the same functions and effects. For example, the terms "first chip" and "second chip" are used solely to distinguish between different chips and do not define their order. Those skilled in the art will understand that terms such as "first" and "second" do not define the quantity or execution order, and do not necessarily define differences.

[0128] Optional, Figure 2 In C, the floating ball 201 may not be displayed or other symbols other than the floating ball 201 may be displayed.

[0129] However, while the above method can achieve collaborative display, it has certain limitations. For example, display area C cannot respond to trigger operations performed by the user, so the payment code in display area C cannot be refreshed, which will lead to abnormal situations such as payment code timeout and payment failure.

[0130] In order to better understand the embodiments of the present application, the structure of the electronic device according to the embodiments of the present application is introduced below. Figure 3 A schematic diagram of the hardware structure of an electronic device provided in an embodiment of the present application.

[0137] The USB interface 130 is an interface that complies with USB standard specifications, and specifically may be a Mini USB interface, a Micro USB interface, a USB Type C interface, etc.

[0138] The charging management module 140 is used to receive charging input from a charger. The power management module 141 is used to connect the charging management module 140 and the processor 110 .

[0139] The wireless communication function of the electronic device can be implemented through antenna 1, antenna 2, mobile communication module 150, wireless communication module 160, modem processor and baseband processor.

[0140] The electronic device realizes the display function through the GPU, the display screen 194, and the application processor. The GPU is a microprocessor for image processing, which connects the display screen 194 and the application processor.

[0141] The display screen 194 is used to display images and videos. In the embodiment of the present application, the electronic device may include a display screen, such as a display screen A, which may include a display area B and a display area C. The meaning of each display area can be found in Figure 1 Description in .

[0142] The electronic device can realize the shooting function through the ISP, camera 193, video codec, GPU, display 194 and application processor.

In the embodiment of the present application, the number of cameras can be multiple, for example, the display A can be provided with a camera 1, the back of the electronic device can be provided with a combination camera, etc. Figure 1 Description in .

[0144] The external memory interface 120 may be used to connect an external memory card. The internal memory 121 may be used to store computer executable program codes, which include instructions.

[0145] The electronic device can implement audio functions such as music playback and recording through the audio module 170, the speaker 170A, the receiver 170B, the microphone 170C, the headphone jack 170D, and the application processor.

[0146] The buttons 190 include a power button, a volume button, and the like.

[0147] The software system of the electronic device can adopt a layered architecture, event-driven architecture, micro-kernel architecture, microservice architecture, or cloud architecture, etc., which will not be described here.

[0148] For example, Figure 4 This is a schematic diagram of the software structure of an electronic device provided in an embodiment of the present application. Figure 4 As shown in Figure 1, the layered architecture divides software into several layers, each with a clear role and division of labor. Layers communicate with each other through software interfaces.

[0149] In some embodiments, the Android system is divided into multiple layers, including, from top to bottom, the application (APP) layer, the application framework layer (or simply referred to as the framework layer), and the driver layer, etc., which is not limited in the embodiments of the present application.

[0150] The application layer may include a series of application packages. The application layer may include one or more of the following: a camera application, a note application, a video application, etc., which is not limited in the embodiments of the present application.

[0151] The application framework layer provides an application programming interface (API) and a programming framework for applications in the application layer.

[0152] The application framework layer includes some predefined interfaces. The application framework layer may include one or more of the following: device state manager service (DSM), display manager service (DMS), power manager service (PMS), window manager service (WMS), display composition system (surface flinger), or floating window framework, etc. Among them, surface flinger can also be translated as interface deliverer, layer processor, etc., which is not limited in the embodiments of this application.

[0153] The device status management module can be used to receive device status requests initiated by the framework layer and dispatch the device status to the display management service and window management service. The device status management module can also determine the device status based on sensor data change messages initiated by sensors and dispatch the device status to the display management service and window management service.

[0154] The device state may include one or more of the following: collaborative display state, folded state, unfolded state, etc. The collaborative display state can be understood as the electronic device collaboratively displaying the application interface in the window of display area B to display area C.

[0155] The display management service can also realize the display management of the logical screen 1 and the virtual screen in the electronic device. The meaning of the logical screen 1 and the logical screen 2 can be found in Figure 13 Description in .

[0156] The power management service can be used to update the power status of the display screen, which can include: power-on state or power-off state.

[0157] The window management service can be used to perform various operations such as moving out of the mirror layer, scaling the mirror layer, obtaining the layer where the floating window is located, and rotating the mirror layer.

[0158] The window management service may include: a display content (DisplayContent) module, a display rotation (DisplayRotation) module, and a display rotation coordination (DisplayRotationCoordinator) module.

[0159] The display content module can be used to transmit the folding state to the display rotation module; the display rotation module can be used to monitor the rotation direction of the electronic device and calculate the rotation direction of the mirror layer in the display area C based on the rotation direction of the electronic device; the display rotation coordination module can be used to return the rotation direction of the electronic device to the display rotation module.

[0160] The display composition system can be used to perform layer composition processing, layer mirroring processing, and other services.

[0161] The floating window framework can be used to implement window management for floating windows and mini windows. For example, in response to a user entering collaborative display, the floating window framework can be used to initiate a collaborative display status request to the device state management service; or, in response to a user exiting collaborative display, the floating window framework can be used to initiate a collaborative display status cancellation request to the device state management service.

[0162] The driver layer is the layer between hardware and software. It drives the hardware to make it work. For example, the driver layer may include a display driver, which powers on and off the display.

[0163] In a possible implementation, the electronic device may include a hardware layer. Figure 4 For example, the hardware layer may include one or more of the following: an organic light-emitting diode (OLED) 1. Part of the display area of ​​OLED 1 may constitute a display area B, and part of the display area of ​​OLED 1 may constitute a display area C.

[0164] It is understandable that the embodiments of the present application do not specifically limit the software layers involved in the software architecture, the modules included in the software layers, and the functions of the modules.

[0165] The following specific embodiments are used to describe in detail the technical solution of the present application and how the technical solution of the present application solves the above technical problems. The following specific embodiments can be implemented independently or in combination with each other. For the same or similar concepts or processes, some embodiments may not be described in detail.

[0166] In the embodiment of the present application, the electronic device is used as Figure 1 Taking the external folding mobile phone shown as an example, the collaborative display process when the external folding mobile phone is in a folded state is illustrated by example. This example does not constitute a limitation on the embodiments of the present application.

[0167] 1. Enter collaborative display ( Figure 5-1 to Figure 5-4 )

[0168] For example, in response to a trigger operation performed by the user on display area C, the electronic device enters collaborative display.

[0169] Optionally, in response to other triggering operations performed by the user, the electronic device enters collaborative display. Other triggering operations may include one or more of the following: multi-finger sliding window operations, dragging the window to a preset area, circling display area B or display area C, air gesture operations, gazing at display area B or display area C, or triggering operations on hardware switches. The embodiments of this application do not limit the method for entering collaborative display.

[0170] For example, Figure 5-1 to Figure 5-4 A schematic diagram of an interface for entering collaborative display provided in an embodiment of the present application.

[0171] When the electronic device is in a folded state, the electronic device may display the interface shown in FIG. 5A in display area B, and the display area C may display the interface shown in FIG. 5B .

[0172] As shown in FIG5A , the interface may display: a note application interface and a floating window 500 covering the note application interface. The floating window 500 may display: the homepage of the payment application and at least one floating window control control.

[0173] The home page of the payment application may include: a scan control, a payment control 50, and a travel control, etc.

[0174] The floating window manipulation controls include one or more of the following: a maximize control 502, a minimize control 503, a drag control (or top bar) 504, or a close control 505. The maximize control 502 is used to display the application interface in the floating window full screen, the minimize control 503 is used to reduce the floating window to a floating ball, the drag control 504 is used to drag the floating window to any position in the interface, and the close control 505 is used to close the floating window.

[0175] In response to the user clicking the payment control 50 in FIG5A , the electronic device may display an interface as shown in FIG5C in display area B, and display area C may be as shown in FIG5D .

[0176] As shown in FIG5C , the interface may display: a note application interface and a floating window 501 covering the note application interface. The floating window 501 may display: a payment interface in a payment application and at least one floating window operation control.

[0177] It can be understood that the note application interface displayed below the floating window 501 is only an example, and the lower side of the floating window 501 can also display other application interfaces or a desktop, and the like, and the embodiments of the present application do not limit this. For example, the lower side of the floating window 501 can display a desktop interface provided by a desktop application, a video playing interface provided by a video playing application, or an interface provided by a shopping application, and the like.

[0178] In response to the trigger operation performed by the user in FIG. 5D on the display area C, the display area B of the electronic device can display the interface as shown in FIG. 5E, and the display area C of the electronic device can display the interface as shown in FIG. 5F. The trigger operation on the display area C can be a tapping operation on the display area C, for example, including one or more of the following: a single tapping operation on the display area C, a double tapping operation on the display area C, or a triple tapping operation on the display area C, and the like.

[0179] As shown in FIG. 5E, the interface can display: a note application interface, and a mini window 506 overlaid on the note application interface. The application interface displayed in the mini window 506 is the same as the application interface displayed in the floating window 501. In this way, after entering the collaborative display, the user can determine the content displayed by the display area C based on the mini window 506, and the display area occupied by the mini window 501 is small, which is also convenient for the user to view other content in other display areas in FIG. 5E.

[0180] Optionally, the prompt information 5 (not shown in FIG. 5E) for prompting that the device is in the collaborative display state can also be displayed in FIG. 5E, and the prompt information 5 can be arranged at any position of FIG. 5E, such as the top or bottom of FIG. 5E, and the like.

[0181] The outer frame around the mini window 506 can be displayed in a thick line manner and / or a colored line manner, or the inside of the mini window 506 can be displayed in any background color, and the like. For example, the outer frame line thickness of the mini window 506 can be greater than the outer frame line thickness of the floating window 501; or the outer frame color of the mini window 506 can be different from the outer frame color of the floating window 501. In this way, the user can determine that the content in the mini window 506 has been mounted in the display area C through the form of the mini window.

[0182] It can be understood that the mini window 506 can be automatically arranged at the upper right corner; or in the case where other mini windows are already displayed at the upper right corner of FIG. 5C, in response to the multi-finger sliding operation performed by the user in FIG. 5C on the floating window 501, the mini window 506 can be automatically arranged at other corners such as the upper left corner, and the like, except for the upper right corner.

[0183] After entering the collaborative display, the mini window 506 can be moved to another position based on the user's dragging, so as to reduce the obstruction of the mini window 506 on other displayed contents in FIG.

[0184] As shown in FIG. 5F , the interface may display a payment interface, which may be the same as the application interface in the floating window 501 .

[0185] The payment interface in FIG5F may be displayed at the top of display area C or in the middle of display area C. When the payment interface is displayed at the top of display area C, the lower side of the payment interface in display area C may be displayed in white or black, etc.; alternatively, when the payment interface is displayed in the middle of display area C, the upper and lower sides of the payment interface in display area C may be displayed in white or black, etc., which is not limited in the embodiments of the present application.

[0186] Optionally, the status bar may not be displayed at the top of the interface in FIG5F. Alternatively, the status bar may be displayed at the top of the interface in FIG5F. The status bar may display one or more of the following identifiers: a Wi-Fi identifier, time information, an operator identifier, a battery identifier, or a notification identifier, etc., which is not limited in the embodiments of the present application.

[0187] Optionally, after entering collaborative display, the electronic device may also highlight the outer frame of the floating window 501 in display area B and display the interface shown in Figure 5F in display area C. In this scenario, the electronic device may not display the mini window 506. Furthermore, in response to the user's operation in Figure 5C of dragging the highlighted floating window 501 to any corner of display area B, the electronic device may display the interface shown in Figure 5E in display area B and continue to display the interface shown in Figure 5F in display area C. The highlighting includes: bold display and / or colored line display.

[0188] Optionally, in response to the user dragging floating window 501 to the upper right corner of display area B in FIG5C , the electronic device may display the interface shown in FIG5G in display area B, and display area C may be as shown in FIG5H . As shown in FIG5G , the interface may include: a note application interface and a mini window 507 overlaid on the note application interface.

[0189] As can be understood, referring to the interfaces shown in Figures 5E and 5G , the outer border around mini window 506 can be highlighted, while the outer border around mini window 507 can be non-highlighted; the interior of mini window 506 can display any background color, while the interior of mini window 507 can display no background color; prompt message 5 can be displayed in Figure 5E , while prompt message 5 can be not displayed in Figure 5G . The outer border around mini window 506 can be a different color than the outer border around mini window 507.

[0190] It should be noted that when the electronic device enters collaborative display based on floating window 501, the outer border around mini window 506 may be highlighted, allowing the user to determine that the device has entered collaborative display by the outer border around mini window 506. When the electronic device shrinks floating window 501 to mini window 507, the outer border around mini window 507 is not highlighted, and the user can determine that the device has not entered collaborative display by the outer border around mini window 507.

[0191] Based on this, in response to the user's trigger operation on display area C in Figure 5D, the electronic device can mirror the application interface in the display area B window to display area C, realizing the coordinated display of the display area B window and display area C.

[0192] Optionally, when the electronic device allows mounting more mini windows, the electronic device may also support collaborative display of the contents of other mini windows in the display area C. In this case, multiple mini windows may be displayed in FIG5E , and the specific process will not be repeated here.

[0193] In a possible implementation, the electronic device may also enter collaborative display based on the user's multi-finger sliding operation of the floating window 501, or the operation of dragging the floating window 501 to a preset area.

[0194] In one implementation, the operation of sliding the floating window 501 with multiple fingers may include: sliding the floating window 501 with three fingers up, sliding the floating window 501 with three fingers down, sliding the floating window 501 with two fingers up, or sliding the floating window with two fingers down, etc. The specific form of the multi-finger sliding operation is not limited in the embodiment of the present application.

[0195] Optionally, in response to the user's three-finger upward swipe on the floating window 501 in Figure 5C , the electronic device may shrink the floating window 501 into a mini window and display the mini window in the upper left corner (or lower right corner) of Figure 5C . Alternatively, in response to the user's three-finger downward swipe on the floating window 501 in Figure 5C , the electronic device may shrink the floating window 501 into a mini window and display the mini window in the lower left corner (or lower right corner) of Figure 5C , etc. In this way, the user can control the display position of the mini window through gesture operation when entering the collaborative display function, thereby improving operational flexibility.

[0196] In another implementation, the preset area can be pre-set at the top area of ​​the interface of display area B. The words "dual-screen collaboration" or "collaborative display" may be displayed in the preset area, or no words may be displayed. For example, the user can trigger collaborative display by dragging the floating window 501 into the preset area, so that the display area B of the electronic device can display the interface shown in Figure 5E, and the display area C of the electronic device can display the interface shown in Figure 5F.

[0197] Optionally, the preset area can also be set on the left side, right side or bottom of the interface as shown in Figure 5C. In the embodiment of the present application, there is no limitation on the display position, area size, area shape, etc. of the preset area.

[0198] In another implementation, when the electronic device displays the full-screen transfer application interface in display area B, in response to the user sliding upward at the bottom of the transfer application interface and dragging the transfer application interface to a preset area, the electronic device can display a mini window 506 in display area B and an interface as shown in Figure 5F in display area C.

[0199] 2. Content synchronization after entering collaborative display ( Figure 6-2 as well as Figure 6-2 )

[0200] For example, Figure 6-1 as well as Figure 6-2 A schematic diagram of a collaborative interaction interface provided in an embodiment of the present application.

[0201] After the electronic device enters the collaborative display, in response to the user performing a click operation on mini window 506 in Figure 5E, the electronic device may display the interface shown in Figure 6A in display area B and the interface shown in Figure 6B in display area C. The content displayed in Figure 6A can be seen in the description of Figure 5C, and the content displayed in Figure 6B can be seen in the description of Figure 5F, which will not be repeated here.

[0202] In response to the user triggering the payment code 600 in floating window 501 in Figure 6A , the electronic device may display the interface shown in Figure 6C in display area B and the interface shown in Figure 6D in display area C. As shown in Figure 6C , the payment code may be displayed in floating window 601; as shown in Figure 6D , the payment code may also be displayed in display area C. The application interface in floating window 601 is different from the application interface in floating window 501.

[0203] Optionally, the outer frames around the floating window 501 and the floating window 601 may be highlighted so that the user can determine that the collaborative display has been entered based on the status of the outer frames around the floating windows.

[0204] Optionally, in response to other triggering operations performed by the user on the floating window 501 in Figure 6A, the electronic device may also display other application interfaces in the floating window 601 and the display area C, and synchronize the application interfaces in the floating window 601 and the display area C.

[0205] For example, in response to the user performing a trigger operation on the payment collection control 602 in FIG. 6A , the display area B may display the interface shown in FIG. 6E , and the display area C may display the interface shown in FIG. 6F .

[0206] As shown in FIG6E , the interface may display: a note application interface and a floating window 603 , wherein the floating window 603 may display a payment interface, wherein the payment interface may display a payment code, etc. The payment interface in FIG6F is the same as the payment interface in the floating window 603 .

[0207] Optionally, in response to the user's triggering operation on display area C in FIG6B , the electronic device may update the display content in display area C and mirror the display content in display area C to a floating window or mini window in display area B. The triggering operation on display area C may be a click operation, a sliding operation, or an operation of inputting information in display area C. In this scenario, the electronic device may synchronize the content of display area C with the window of display area B based on the user's triggering operation on display area C, thereby realizing coordinated display of the windows of display area C and display area B.

[0208] Based on this, in response to the user's operation performed on display area B in Figure 6A, the application interface in floating window 601 (or floating window 603) can be updated synchronously with the application interface in display area C, so that the user can view the latest application interface in display area C in real time.

[0209] 3. Unable to enter collaborative display ( Figure 7 )

[0210] The electronic device can also display the transfer interface of the financial application in the floating window of the display area B (such as Figure 7 A floating window 701 in the interface), the display area C can be Figure 7 B. In response to the user Figure 7 For the operation of tapping the display area C performed in B, the electronic device can prompt the user that collaborative display is not possible when determining that the application interface in the floating window 701 is a security and privacy interface.

[0211] It is understandable that the electronic device can prompt the user in display area B and / or display area C that collaborative display is not possible.

[0212] In one implementation, in response to a user Figure 7 B performs the operation of tapping the display area C. When the electronic device determines that the application interface in the floating window 701 has a security privacy mark (such as flag_secure), the electronic device can display the following in the display area B: Figure 7 The interface shown in C is displayed in the display area C. Figure 7 The interface shown in D.

[0213] like Figure 7 As shown in FIG. 3 , the interface may display: a note application interface and a mini window 702. The outer frame around the mini window 702 may not be highlighted, which is not limited in the embodiment of the present application.

[0214] like Figure 7 As shown in D, a prompt message 703 may be displayed in the interface. The prompt message 703 is used to remind the user that the mirrored display interface is a security and privacy interface and does not support collaborative display.

[0215] In another implementation, in response to the user Figure 7 In the operation of tapping display area C performed in B, when the electronic device determines that the application interface in the floating window 701 has flag_secure, the electronic device can also display prompt information 703 in display area B. At this time, display area C can maintain low power consumption. In this scenario, display area C is in low power consumption, reducing power waste.

[0216] In another implementation, in response to the user Figure 7 The operation of tapping display area C performed in B, when the electronic device determines that the application interface in the floating window 701 has flag_secure, the electronic device can also display prompt information 703 in display area B and display area C at the same time, which is not limited in the embodiment of the present application.

[0217] Based on this, the electronic device determines whether to enter collaborative display according to the attributes of the interface, and prompts the user when it is determined that collaborative display cannot be entered, so as to improve the user experience of using the collaborative display function.

[0218] 4. Status prompt after entering collaborative display ( Figure 8 )

[0219] After entering collaborative display, in response to the user's operation of opening the notification center, the electronic device may display a prompt message indicating that the collaborative display state is currently in display area B. The operation of opening the notification center may include: the user swiping down from the upper left corner of display area B, etc.

[0220] For example, Figure 8 A schematic diagram of an interface for prompting collaborative display status provided in an embodiment of the present application.

[0221] In response to the user's operation of opening the notification center in FIG5E, the electronic device may display the following information in the display area B: Figure 8 The interface shown in A, and the interface shown in display area C continues to be displayed as follows Figure 8 The interface shown in B. Figure 8 As shown in Figure A, the notification center of the interface may include: prompt information 801, which may be used to prompt that the collaborative display state is currently in progress. An exit control 802 may be displayed around the prompt information 801, which may be used to exit the collaborative display state.

[0222] Optionally, other information may also be displayed around the prompt information 801, such as time information for indicating the duration of the collaborative display, and / or an application identifier for displaying the collaborative display, etc., which is not limited in the embodiments of the present application.

[0223] Optionally, the prompt information 801 and the exit control 802 may also be displayed at any position as shown in FIG. 5E , so that the user can determine that the user is currently in the collaborative display state without opening the notification center.

[0224] Optionally, in response to the user Figure 8 The electronic device may terminate the collaborative display by triggering the exit control 802 executed in A. The electronic device may display the following in the display area B: Figure 8 The interface shown in C, display area C can be Figure 8 D. At this time, compared with Figure 5E, Figure 8 The outer frame around the mini window 803 in C is not highlighted, etc. In the embodiment of the present application, there is no limitation on the interface displayed by the electronic device after exiting the collaborative display based on the exit control 802.

[0225] In a possible implementation, the electronic device may also exit the collaborative display state when detecting at least one of the following exit operations. For example, the exit operation may include one or more of the following: the operation of expanding the electronic device, the operation of turning off the screen, the operation of switching the floating window to a floating ball when the window is in a floating window state, the operation of switching the mini window to a floating ball when the window is in a mini window state, the operation of displaying the content in the floating window in full screen when the window is in a floating window state, or the operation of exiting the floating window when the window is in a mini window state, etc.

[0226] For example, the operation of switching the floating window to a floating ball may include: triggering the minimize control 503 in Figure 5, etc. The operation of displaying the content in the floating window in full screen may include: triggering the maximize control 502 in Figure 5, etc. The operation of exiting the floating window may include: triggering the close control 505 in Figure 5, etc.

[0227] Based on this, the user can determine the status of the electronic device according to the prompt information 801 in the notification center, and trigger the exit control 802 when it is necessary to exit the collaborative state.

[0228] 5. Device rotation after entering collaborative display ( Figures 9-1 to 10-2 )

[0229] After the electronic device enters the collaborative display based on the embodiment corresponding to FIG5 , the electronic device can determine how to display the content of the floating window in the display area C according to the display direction of the display area C and the display method of the floating window. For example, when the floating window is in landscape display, the electronic device can determine how to display the content of the floating window in the display area C according to the display direction of the floating window and the display method of the floating window. Figure 9-1 as well as Figure 9-2 Alternatively, when the floating window is displayed in portrait mode, the electronic device may display the floating window in a coordinated manner according to the description in Figure 10-1 as well as Figure 10-2 The description in is displayed in coordination.

[0230] Figure 9-1 as well as Figure 9-2 A schematic diagram of a collaborative display interface in which a floating window is displayed in landscape mode, provided in an embodiment of the present application.

[0231] The electronic device can display the interface shown in Figure 9A in display area B. This interface can display a floating window 901, which can display video content from any application. For example, floating window 901 can be in landscape mode, or it can be understood that floating window 901 can display video 1 in landscape mode. The camera can be located in the upper right corner of display area B. Figure 9A shows the interface displayed in display area B of the electronic device in portrait mode.

[0232] When the display area B of the electronic device displays as shown in Figure 9A, the display area C of the electronic device displays the interface shown in Figure 9B. As shown in Figure 9B, the display area C is in portrait mode, and Video 1 can be displayed in landscape mode in the middle of the display area C. The upper and lower sides of Video 1 may not display any content (for example, the upper and lower sides of Video 1 may be black), or they may be displayed in white, etc. Figure 9B can be understood as the interface displayed when the electronic device is not rotated. For example, the rotation angle of the electronic device can be 0 degrees, that is, the electronic device has not rotated.

[0233] As described in Figures 9A and 9B, since the floating window 901 is in a horizontal state and the display area C is in a vertical state (or it can be understood that the display direction of the floating window is different from the display direction of the display area C), video 1 can be displayed horizontally in the middle area of ​​display area C after being scaled proportionally. At this time, video 1 cannot be displayed in full screen in display area C.

[0234] Optionally, when the display direction of the floating window is different from the display direction of the display area C, prompt information 1 (not shown in Figure 9) can also be displayed in the interface shown in Figure 9A (or Figure 9B, or Figure 9E, or 9F, etc.), and prompt information 1 is used to prompt the user to rotate the display screen to obtain a better visual experience.

[0235] When display area B displays as shown in Figure 9A and display area C displays as shown in Figure 9B, in response to the user rotating the electronic device 90 degrees clockwise, the electronic device can display in display area B as shown in Figure 9C and in display area C as shown in Figure 9D.

[0236] As shown in FIG9C , display area B is in landscape mode, and the camera can be located in the upper left corner of display area B. As shown in FIG9D , display area C is in landscape mode, and video 1 can be displayed full screen in display area C. At this time, the rotation angle of the electronic device can be 90 degrees. Thus, floating window 901 is in landscape mode and display area C is in landscape mode (or the display direction of the floating window is the same as that of display area C), and the content in floating window 901 can be displayed full screen in display area C for easy viewing by the user.

[0237] When display area B displays as shown in Figure 9C and display area C displays as shown in Figure 9D, in response to the user rotating the electronic device 90 degrees clockwise, the electronic device can display the interface as shown in Figure 9E in display area B and the interface as shown in Figure 9F in display area C.

[0238] As shown in FIG9E , display area B is in portrait mode, and the camera can be located in the lower left corner of display area B. As shown in FIG9F , display area C is in portrait mode, and video 1 cannot be displayed in full screen in display area C. At this time, the rotation angle of the electronic device can be 180 degrees.

[0239] When display area B displays as shown in Figure 9E and display area C displays as shown in Figure 9F, in response to the user rotating the electronic device 90 degrees clockwise, the electronic device can display the interface as shown in Figure 9G in display area B and the interface as shown in Figure 9H in display area C.

[0240] As shown in Figure 9G, display area B is in landscape mode, and the camera can be located in the upper left corner of display area C. As shown in Figure 9H, display area C is in landscape mode, and video 1 can be displayed full screen in display area C. At this time, the rotation angle of the electronic device can be 270 degrees. In this way, floating window 901 is in landscape mode and display area C is in landscape mode (or it can be understood that the display direction of the floating window is the same as the display direction of display area C), and the content in floating window 901 can be displayed full screen in display area C, making it easier for users to view.

[0241] akin, Figure 10-1 as well as Figure 10-2 A schematic diagram of a collaborative display interface in which a floating window is displayed in portrait mode, provided in an embodiment of the present application.

[0242] The electronic device can display the interface shown in Figure 10A in display area B, in which a floating window 1001 can be displayed. The floating window 1001 can display video content from any application. For example, the floating window 1001 can be in a vertical state, or it can be understood that the floating window 1001 can display Video 2 in a vertical state. The camera can be located in the upper right corner of display area B.

[0243] It is understood that Figure 10A may be an interface displayed in display area B of the electronic device in portrait mode. When the electronic device is in landscape mode, the electronic device may also display a floating window 1001 in portrait mode in display area B. At this time, the content displayed in display area B may be similar to that in Figure 10C and will not be repeated here.

[0244] When the display area B of the electronic device is displayed as shown in Figure 10A, the display area C of the electronic device displays the interface shown in Figure 10B. As shown in Figure 10B, the display area C is in a vertical screen state, and the video 2 can be displayed in full screen in the display area C. Figure 10B can be understood as the interface displayed when the electronic device is not rotated, for example, the rotation angle of the electronic device can be 0 degrees. In this way, the floating window 1001 is in a vertical screen state and the display area C is in a vertical screen state (or it can be understood that the display direction of the floating window is the same as the display direction of the display area C), and the content in the floating window 1001 can be displayed in full screen in the display area C, which is convenient for the user to view.

[0245] When display area B displays as shown in Figure 10A and display area C displays as shown in Figure 10B, in response to the user rotating the electronic device 90 degrees clockwise, the electronic device can display in display area B as shown in Figure 10C and in display area C as shown in Figure 10D.

[0246] As shown in FIG10C , display area B is in landscape mode, and the camera can be located in the lower right corner of FIG10C . As shown in FIG10D , display area C is in landscape mode, and video 2 cannot be displayed full screen in display area C. The left and right sides of video 2 may not display anything (or the left and right sides of video 2 may be black). At this time, the rotation angle of the electronic device can be 90 degrees.

[0247] Optionally, as described in FIG10C and FIG10D, when the display direction of the floating window is different from the display direction of the display area C, FIG10C (or FIG10D, or FIG10G, or FIG10H) may also display prompt information 1, and the content of prompt information 1 can be found in FIG10C. Figure 9-1 Description in .

[0248] When display area B displays as shown in Figure 10C and display area C displays as shown in Figure 10D, in response to the user rotating the electronic device 90 degrees clockwise, the electronic device can display in display area B as shown in Figure 10E and in display area C as shown in Figure 10F.

[0249] As shown in FIG10E , display area B is in portrait mode, and the camera can be located in the lower left corner of display area B in FIG10E ; as shown in FIG10F , display area C is in portrait mode, and video 2 can be displayed full screen in display area C. At this time, the rotation angle of the electronic device can be 180 degrees. In this way, the floating window 1001 is in portrait mode and display area C is in portrait mode (or it can be understood that the display direction of the floating window is the same as the display direction of display area C), and the floating window 1001 can be displayed full screen in display area C, which is convenient for the user to view.

[0250] In the case that display area B displays as shown in FIG. 10E and display area C displays as shown in FIG. 10F, in response to the user rotating the electronic device by 90 degrees clockwise, the electronic device can display as shown in FIG. 10G in display area B and as shown in FIG. 10H in display area C.

[0251] As shown in FIG. 10G, display area B is in a horizontal screen state, and the camera can be located at the upper left corner of display area B in FIG. 10G; as shown in FIG. 10H, display area C is in a horizontal screen state, and video 2 cannot be displayed full screen in display area C. At this time, the rotation angle of the electronic device can be 270 degrees.

[0252] Based on the description in Figures 9-1 to 10-2 When the display direction of the floating window is different from the display direction of display area C, the electronic device can prompt the user to rotate the phone in display area B (or display area C) to obtain a better experience; or when the display direction of the floating window is the same as the display direction of display area C, the content in the floating window can be displayed full screen in display area C, which is convenient for the user to view.

[0253] It can be understood that Figures 9-1 to 10-2 The position of the camera in the display area described in

[0254] 6. Abnormal scenarios in the cooperative display process Figure 11-1 and Figure 11-2 )

[0255] The abnormal scenario can include: the percentage of the battery power of the electronic device is lower than a value 1, and / or the temperature of the electronic device is higher than a value 2, etc. The present application embodiments are not limited thereto. The value 1 can be 20% or the like, and the value 2 can be 40 degrees Celsius or the like.

[0256] The following will be described by taking the temperature of the electronic device being higher than the value 2 as an example, which does not constitute a limitation to the present application embodiments.

[0257] In one implementation, after the electronic device enters the cooperative display, the electronic device can display the interface as shown in FIG. 11A in display area B when it is detected that the temperature of the electronic device is higher than the value 2, and display area C can display the interface as shown in FIG. 5F at this time.

[0258] As shown in Figure 11A, the interface may display: a note application interface, a mini window 506, and a prompt box 1101. Prompt box 1101 may include: a control 1102 (with the word "Yes"), a control 1103 (with the word "No"), and a prompt message 1104. Control 1102 is used to exit collaborative display, control 1103 is used to refuse to exit collaborative display, and prompt message 1104 is used to prompt the user that the device temperature is detected to be high and whether to exit collaborative display.

[0259] For example, when the electronic device receives a user operation on control 1103, the electronic device may display the interface shown in Figure 11B in display area B, while display area C may continue to display the interface shown in Figure 5F. Alternatively, when the electronic device receives a user operation on control 1102, the electronic device may display the interface shown in Figure 11C in display area B, while display area C may display the interface shown in Figure 5D. In Figure 11C, the outer border around mini window 1100 is not highlighted.

[0260] Optionally, after the electronic device enters the collaborative display, the electronic device may display a prompt box 1101 in the display area C when an abnormal scene is detected, or directly exit the collaborative display.

[0261] In another implementation, when the temperature of the electronic device is higher than a value of 2, in response to the user entering the collaborative display operation, the electronic device can display the interface shown in Figure 11D in display area B. At this time, display area C can be in a black screen state or can also display other application interfaces.

[0262] As shown in FIG11D , the interface may display: a note application interface and a prompt box 1105. Prompt box 1105 may include a control 1107 (with the word "Yes"), a control 1108 (with the word "No"), and a prompt message 1106. Control 1107 is used to enter collaborative display, control 1108 is used to refuse to enter collaborative display, and prompt message 1106 is used to prompt the user that the device temperature is detected to be high and whether to continue to enter collaborative display.

[0263] For example, when the electronic device receives a user operation on control 1107, the electronic device may display the interface shown in FIG11E in display area B, and display area C may display the interface shown in FIG5F. Alternatively, when the electronic device receives a user operation on control 1108, the electronic device displays the interface shown in FIG11F, and display area C may remain black or display other application interfaces.

[0264] Based on this, since the collaborative display function has high power consumption and / or battery requirements, the electronic device can promptly prompt the user whether to exit the collaborative display (or whether to enter the collaborative display) when an abnormal scenario is detected, thereby reducing the situation where the device power drops rapidly or the device freezes without the user's perception.

[0265] 7. Exit collaborative display ( Figure 12 )

[0266] After entering the collaborative display, the electronic device may also exit the collaborative display when receiving an operation to expand the electronic device.

[0267] Figure 12 A schematic diagram of an interface for collaborative display in a subsequent scenario provided in an embodiment of the present application.

[0268] In the case where the display area B of the electronic device displays the interface shown in FIG. 5E and the display area C displays the interface shown in FIG. 5F, in response to the user's operation of unfolding the electronic device, the electronic device may display the interface shown in FIG. 5E on the display screen A. Figure 12 The interface shown in A.

[0269] Figure 12 Area A may include: a note application interface and mini window 1201. It is understood that, because unfolding the electronic device will exit the collaborative display, the outer border around mini window 1402 may not be highlighted. It is understood that when the electronic device receives the user's unfolding operation, the electronic device may connect the content in display area B to display screen A.

[0270] You can understand that other methods of exiting collaborative display can be found in Figure 8 The description of the place will not be repeated here.

[0271] Based on this, in response to the user's operation of folding the electronic device, the electronic device can exit the collaborative display and continue to display the content displayed in area B on display screen A.

[0272] above Figure 5-1 to Figure 12 The application interface involved in collaborative display is schematically explained below. Figure 13 The architecture of collaborative display is schematically explained, combined with Figure 14-16 The description in , explains the interface display method for realizing collaborative display.

[0273] For example, Figure 13 This is a schematic diagram of a collaborative display architecture provided by an embodiment of the present application. Figure 13 As shown, the interface display method can be applied to business scenarios using foldable screen mobile phones.

[0274] The foldable screen mobile phone may include: OLED1, OLED1 can realize the capabilities of display area B and display area C. The meaning and form of display area B and display area C can be found in Figure 1 Description in .

[0275] To facilitate the management of display content on the display screen, the electronic device can generate a physical display corresponding to the OLED and a logical display corresponding to the physical display at the framework layer, and manage the physical display and the logical display through the display management service.

[0276] The physical screen can be a display screen mapped by the electronic device based on the reading of the OLED. The screen information of the physical screen can be the same as the screen information of the OLED. For example, the screen information can include screen resolution or screen size. The screen information of the physical screen cannot be changed. For example, the electronic device can map the physical screen 1 corresponding to the display screen A by reading the screen information of OLED1.

[0277] In order to facilitate control of display of different display areas in the physical screen, the electronic device may map a logical screen corresponding to the physical screen, and the screen information of the logical screen may be different from the screen information of the physical screen.

[0278] A logical screen can be understood as an abstract screen that handles the content and layout of a physical screen. For example, a logical screen can configure the display area, display location coordinates, and display orientation of the corresponding physical screen. For example, an electronic device generates logical screen 1, which is associated with physical screen 1. Logical screen 1 can implement the interface display of any display area on display screen A.

[0279] In a possible implementation, to facilitate displaying an application interface in a portion of the OLED area, the electronic device can create a virtual screen when it is powered on or when an interface display is required in display area C, generate a virtual physical screen corresponding to the virtual screen, and generate a logical screen 2 corresponding to the virtual screen. The virtual screen can be used to control the electronic device to display the interface in display area C. The virtual physical screen can be determined based on the screen information of the virtual screen, and the screen information of the virtual screen can be set by the electronic device.

[0280] like Figure 13 As shown, when the electronic device is in the folded state, the electronic device can generate a physical screen 1 by reading the screen information of OLED 1. Data can be transmitted between the physical screen 1 and OLED 1 through the display serial interface (DSI)-1. The physical screen 1 can correspond to the logical screen 1 in the framework layer.

[0281] When the electronic device is turned on or detects that the device is in a folded state, it can create a virtual screen and set the display of the virtual screen to the display area of ​​display area C, generating a virtual physical screen and a logical screen 2 corresponding to the virtual screen. Data can also be transmitted between the virtual physical screen and OLED1 through DSI-1, and there is a corresponding relationship between the virtual physical screen and the logical screen 2.

[0282] Among them, DSI can be used to transmit image data, control signals, etc. in the controller to the OLED.

[0283] It can be understood that since both the physical screen 1 and the virtual screen are composed of a portion of the display area in the display screen A, the display in the physical screen 1 and the virtual screen is realized by the OLED 1 .

[0284] The following is a schematic description of the different display areas. Figure 14 A schematic diagram of a display area provided in an embodiment of the present application.

[0285] When the electronic device is in the unfolded state, when the electronic device displays an interface through display screen A, the electronic device can set the display area to the full-screen display area, so that the electronic device can start the interface display from the starting position 1 and complete the interface display at the ending position 1. The full-screen display area includes: display area 101, folded area, and display area 102.

[0286] When the electronic device is in the folded state, when the electronic device displays an interface through display area B, the electronic device can set display area 102 so that the electronic device can start displaying the interface from starting position 2 and complete the interface display at end position 2. In this case, display area 101 and the folded area can be in a low power state, for example, display area 101 and the folded area can be in a black screen state. The offset between starting position 2 and starting position 1 can be offset 1.

[0287] When the electronic device is in the folded state, when the electronic device displays an interface through display area B and display area C, the electronic device can set the full-screen display area to ensure that both display area B and display area C can be displayed on display screen A. In this case, after the full-screen display area is successfully set, the electronic device will start displaying the content in display area B and display area C from starting position 1. Therefore, the electronic device can offset the layer of display area B to display area 102 to reduce the overlapping display of content in display area B and display area C. For the specific implementation process, please refer to the description of S1508-S1510.

[0288] based on Figure 13-14 Description in Figure 15A module interaction schematic diagram of an interface display method provided in an embodiment of the present application is shown in Figure 15 In a corresponding embodiment, the electronic device can include a device state management service, a display management service, a window management service, a display compositing system, etc., and the meaning of any module can be referred to the description in Figure 4 .

[0289] It can be understood that the display area B and the display area C are both displayed in the display screen A. In the case that the electronic device is in the folded state, the electronic device can create a virtual screen so that the virtual screen can display the content in the display area C. Since the virtual screen does not exist a display layer, the electronic device can ensure that the content in the virtual screen can be normally displayed by setting the virtual screen as a default display screen. The virtual screen set as the default display screen can be understood as displaying the content in the virtual screen in the display area C.

[0290] As shown in Figure 15 , the interface display method can include the following steps:

[0291] S1501, in response to the coordination display operation for the target application, the device state management service receives the coordination display state request.

[0292] The target application can be an application running in the foreground. For example, the target application can be an application displayed in the floating window. It can be understood that the application not running in the foreground cannot respond to the user's coordination display operation.

[0293] The coordination display operation can include: Figure 5-1 to Figure 5-4 the triggering operation for the display area C, etc. described in the foregoing embodiments.

[0294] The coordination display state is one of the device states, and the coordination display state can be understood as the state when the electronic device mirrors the content displayed in the display area B window to the display area C. For example, the electronic device can define the coordination display state in / vendor / etc / devicestate in advance.

[0295] The coordination display state can include a flag 1, which can be flag_cancel_with_request_not_on_top. The flag 1 can be understood as that when the target application is not the foreground application, the coordination display state request fails. Alternatively, the flag 1 can also be understood as that the coordination display state can only be successfully requested when the target application runs in the foreground. In this way, when the electronic device detects that the target application does not run in the foreground, the coordination display state can be cancelled, reducing the waste of power consumption.

[0296] For example, the floating window frame in the framework layer can send a collaborative display state request to the device state management service by calling requestState(), and requestState() can include an identifier of the collaborative display state.

[0297] S1502. In response to the collaborative display state request, the device state management service updates the device state to the collaborative display state.

[0298] For example, the device state management service can calculate whether the collaborative display state can be sent by calling onOverrideRequestStatechangedLocked().

[0299] When the collaborative display state includes an active state (status_active) flag, the device state management service determines that the collaborative display state can be issued, and then updates the device state to the collaborative display state by calling updatePendingStateLocked(). updatePendingStateLocked() may include: the collaborative display state flag.

[0300] Alternatively, when the collaborative display status includes the cancel status (status_cancel) flag, the device status management service determines that the collaborative display status cannot be issued, that is, the device status management service cannot dispatch the collaborative display status. At this time, it can be understood that the collaborative display process is ended.

[0301] The inclusion of status_active in the collaborative display state can be understood as the electronic device requesting the collaborative display state; the inclusion of status_cancel in the collaborative display state can be understood as the electronic device requesting to cancel the collaborative display state.

[0302] S1503. The device status management service submits the collaborative display status to the local device.

[0303] For example, the device state management service may commit the collaborative display state through commitPendingState(), which may include an identifier of the collaborative display state.

[0304] S1504. The device status management service dispatches the collaborative display status.

[0305] During the collaborative display state dispatch process, the device state management service can obtain services that pre-registered for the collaborative display state, such as the display management service and the window management service, and then execute S1505 and S1511. For example, the device state management service can obtain services that pre-registered for the collaborative display state through notifyDeviceStatePreCallback(). notifyDeviceStatePreCallback() can include the identifier of the collaborative display state.

[0306] It can be understood that S1502-S1504 can all be understood as an illustration of a process of an electronic device distributing a device status, and this embodiment of the present application does not specifically limit this.

[0307] After S1504, the device status management service can simultaneously (or successively) execute the steps shown in S1505 and S1511 to notify the display management service and the window management service that the device is currently in a collaborative display state. Then, the electronic device can determine the display position of the virtual screen based on S1506-S1510, and execute the layer mirroring process based on S1512-S1520.

[0308] S1505. The display management service receives a status change message 1 from the device status management service.

[0309] The state change message 1 may be used to indicate that the device state has changed, and the state change message 1 may include an identifier of the collaborative display state. For example, the display management service may receive the state change message 1 dispatched by the device state management service through the callback function onStateChanged().

[0310] S1506 . In response to the status change message 1 , the display management service sets the display area of ​​the logical screen 1 to the display area 102 .

[0311] For example, the display management service may set the logical screen 1 to the display area 102 by calling setDisplayOffsets(), where the offset value 1 may be included in setDisplayOffsets().

[0312] It is understood that when the electronic device is in the folded state, the electronic device can set the display area of ​​the logical screen 1 to the display area 102 based on the step shown in S1506, so as to prevent the content in the logical screen 1 from being displayed in the center of the display screen A. In addition, after S1506, the electronic device can receive a trigger operation of the user on the display area 102.

[0313] Optionally, S1507 , the display management service sets the size of the logical screen 1 and the size of the virtual screen.

[0314] For example, the display management service may set the size of the logical screen 1 to the size of the display area 102 and the size of the virtual screen to the size of the display area 101 by calling setDisplayInfoOverrideFromWindowManagerInternal().

[0315] It is understandable that, in the case where the display management service pre-sets the logical screen 1 size and the virtual screen size, the display management service may not execute the step shown in S1507.

[0316] After S1506 , the display management service may execute the following steps S1508 - S1510 simultaneously or sequentially; the display composition system executes S1511 , ie, the display composition system responds to the instructions described in S1508 - S1510 simultaneously.

[0317] S1508: The display management service display synthesis system sets a full-screen display area.

[0318] The meaning of the full screen display area can be found in Figure 14 After setting the full screen display area, the contents of the logical screen 1 and the virtual screen can be displayed starting from the starting position 1.

[0319] S1509 . The display management service notifies the display composition system to shift the display layer of the logical screen 1 to the display area 102 .

[0320] The display layer can also be referred to as a layer. It is understood that the display management service can offset the display layer of the logical screen 1 to the display area 102 through S1509 to reduce the overlap of the content in the virtual screen and the content in the logical screen 1 when the full screen display area is set.

[0321] For example, the display management service may offset the display layer of the logical screen 1 to the display area 102 by calling setPosition().

[0322] Combined with the description in S1508-S1509, it can be understood that in order to realize the interface display of multiple display areas in display screen A, the electronic device can set the full-screen display area based on S1508 to ensure the normal display of display screen A; furthermore, the electronic device can set the display area to an appropriate position by moving the display layer.

[0323] For example, in electronic devices such as Figure 1In the case of the foldable-screen phone described above, the electronic device can move the display layer of the logical screen 1 from the starting position 1 to the starting position 2 based on S1509, to ensure that the display area B and the display area C do not overlap. Alternatively, in the case of an electronic device of other structures, the electronic device can also move the display layer of the virtual screen to ensure that the display area B and the display area C do not overlap, which is not limited in the embodiments of the present application.

[0324] S1510, the display management service notifies the display composition system to set the virtual screen as the default display screen.

[0325] It can be understood that, since the virtual screen has no display layer, the electronic device can set the virtual screen as the default display screen, so that the content set in the virtual screen can be displayed in the display area 101. For example, the display management service can set the virtual screen as the default display screen by calling setLayerStack().

[0326] S1511, the display composition system performs setting the full-screen display area, offsetting the display layer of the logical screen 1 to the display area 102, and setting the virtual screen as the default display screen.

[0327] S1512, the device state management service sends a state change message 1 to the window management service.

[0328] The meaning of the state change message 1 can be referred to the description in S1505, which will not be repeated here.

[0329] In a possible implementation, after S1512, the window management service determines whether there is a mirror layer.

[0330] The mirror layer can be a kind of preset defined layer, and the mirror layer can be understood as a layer obtained by mirroring (or copying) other layers.

[0331] The window management service can obtain the mirror surface, and determine whether there is a mirror layer according to whether the mirror surface is empty. When the mirror surface is empty, it is determined that there is no mirror layer, and the window management service performs the steps shown in S1513-S1519; or when the mirror surface is not empty, it is determined that there is a mirror layer, and the window management service removes the mirror layer, and then performs the steps shown in S1513-S1519.

[0332] S1513, the window management service traverses a task 1 in a preset window.

[0333] The preset window may be a window including a preset window type (window_mode), and may include a floating window or a mini window.

[0334] 5C , Task 1 in the preset window may be a task of the note application in the floating window. For example, the window management service may obtain Task 1 in the preset window by calling forAllRootTasks().

[0335] S1514. The window management service obtains layer 1 under task 1.

[0336] Task 1 can be understood as the parent node of Layer 1, and Layer 1 can be understood as all layers mounted under Task 1. In Figure 5C, Layer 1 can be the layer displayed in the note application. There can be at least one Layer 1. For example, the window management service can use getSurfaceControl() to obtain Layer 1 under Task 1.

[0337] S1515. The window management service sends a message to the display composition system to instruct the layer 1 to be mirrored.

[0338] For example, the window management service can call mirrorSurface() to notify the display composition system to mirror layer 1 to obtain a mirrored layer.

[0339] S1516: The display synthesis system mirrors layer 1 to obtain a mirrored layer.

[0340] S1517: The display composition system returns the mirror layer to the window management service.

[0341] S1518. The window management service scales the mirror layer according to the virtual screen size and the horizontal and vertical status of the virtual screen.

[0342] The window management service can call updateMirroredSurface() to scale the mirrored layer proportionally based on the virtual screen's width and height, as well as its portrait or landscape orientation, so that the mirrored layer can be fully displayed on the virtual screen. For example, when the virtual screen is in portrait mode and the mirrored layer is displayed in portrait mode (or the floating window corresponding to the mirrored layer is in portrait mode), the electronic device can make the width of the mirrored layer the same as the width of the virtual screen and scale the height of the mirrored layer proportionally.

[0343] S1519. The window management service mounts the image layer to the virtual screen.

[0344] For example, the window management service can implement mounting the mirror layer to the virtual screen by calling reparent(). The reparent() can include an identifier of the virtual screen. After the electronic device completes mirroring of layer 1, the electronic device can display the interface as shown in FIG. 5F in display area C.

[0345] Based on this, the electronic device can implement cooperative display of the application interface in the display area B window to the display area C by setting the position of the virtual screen and the step of mirroring a certain layer in the display area B, to improve the user experience of using the electronic device.

[0346] In Figure 15 In the case of implementing cooperative display in the corresponding embodiment, the application embodiment further provides a way of exiting cooperative display, which is described in Figure 16 .

[0347] An exemplary Figure 16 module interaction diagram for exiting cooperative display is provided for the application embodiment. In Figure 16 In the corresponding embodiment, the electronic device can include a device state management service, a display management service, a window management service, a display compositing system, and the like.

[0348] As Figure 16 shown, the method for exiting cooperative display can include the following steps:

[0349] S1601, in response to the operation of unfolding the electronic device performed by the user, the device state management service receives a sensor data change message reported by the sensor.

[0350] The sensor data change message is used to indicate that the sensor of the electronic device has detected a data change. For example, the sensor data change message can be onSensorChanged(), and the sensor data change message can include a sensor event (sensorEvent). The sensorEvent can include the type of sensor, the timestamp of the occurrence of the sensor event, and the data detected by the sensor.

[0351] For example, in response to the operation of unfolding the electronic device performed by the user, the device state management service can receive data such as a folding angle of 180 degrees in the sensor data change message, and based on the data of the folding angle of 180 degrees, it can be understood that the electronic device is in an unfolded state.

[0352] It is understandable that the electronic device may execute the steps shown in S1602-S1610 when it is determined that the collaborative display is exited due to a change in sensor data. Alternatively, when the sensor data has not changed and the electronic device receives a preset exit operation, the electronic device may also execute the steps shown in S1603-S1610 based on the received request to cancel the collaborative display state. Among them, the preset exit operation may include one or more of the following: the operation of switching the floating window to a floating ball when the window is in a floating window state, the operation of switching the mini window to a floating ball when the window is in a mini window state, the operation of displaying the content in the floating window in full screen when the window is in a floating window state, or the operation of exiting the floating window when the window is in a mini window state, etc.

[0353] For example, in response to the user's exit operation of the floating window, the floating window frame in the framework layer can send a request to cancel the collaborative display state to the device state management module. In response to the request to cancel the collaborative display state, the electronic device can execute the steps shown in S1603-S1610.

[0354] The collaborative display state cancel request is used to cancel the collaborative display state requested in S1501. For example, the collaborative display state cancel request may be: cancelStateRequest(), which may include the identifier of the collaborative display state.

[0355] S1602: In response to the sensor data change message, the device state management service dispatches a development state.

[0356] For example, upon receiving a sensor data change message, the device state management service can determine that the device is in the expanded state, update the device state to the expanded state by calling updatePendingStateLocked(), commit the expanded state through commitPendingState(), and then dispatch the expanded state through notifyDeviceStatePreCallback().

[0357] In S1602 , updatePendingStateLocked(), commitPendingState(), and notifyDeviceStatePreCallback() may all include an identifier of the deployment state.

[0358] After S1602, the device status management service can simultaneously (or successively) execute the steps shown in S1603 and S1605 to notify the display management service and the window management service that the device is currently in the expanded state, and then the electronic device can remove the mirror layer based on S1603 and clear the settings for the virtual screen based on S1606-S1610.

[0359] S1603. The device state management service sends a state change message 2 to the window management service.

[0360] The state change message 2 may be used to indicate that the device state has changed. For example, the state change message may include an identifier of the expanded state. For example, the device state management service may notify the window management service of the device state change by calling onStateChanged().

[0361] S1604. In response to the device change message 2, the window management service removes the mirror layer.

[0362] It is understandable that the window management service can remove the mirror layer when determining that the device change message 2 does not include the collaborative display state identifier. The step of removing the mirror layer by the window management service can be referred to the description in S1513 and will not be repeated here.

[0363] S1605. The device state management service sends a state change message 2 to the display management service.

[0364] The meaning of the state change message 2 can be found in the description of S1603 and will not be repeated here.

[0365] S1606 : The display management service cancels setting the display area of ​​the logical screen 1 as the display area 102 in response to the status change message 2 .

[0366] For example, when the display management service executes S1506, the display management service can call setDisplayOffsets() to notify the display composition system to cancel setting the display area of ​​logical screen 1 to display area 102. This can reduce the situation where the display content is still displayed in display area 102 in the expanded state.

[0367] Optionally, S1607 , the display management service sets the size of display screen A.

[0368] For example, the display management service can set the size of display A by calling setDisplayInfoOverrideFromWindowManagerInternal().

[0369] It is understandable that, in the case where the display management service pre-sets the size of the display screen A, the display management service may not execute the step shown in S1607.

[0370] S1608. The display management service notifies the display synthesis system to set a full-screen display area.

[0371] It is understandable that, in the case where the display management service has already set the full-screen display area, the display management service may not execute the step shown in S1608.

[0372] S1609 . The display management service notifies the display composition system to clear the offset of the display layer of logical screen 1 .

[0373] For example, when the display management service executes S1509, the display management service can call setPosition() to clear the display layer offset of logical screen 1. Clearing the display layer offset of logical screen 1 can be understood as moving the display layer of logical screen 1 from starting position 2 to starting position 1.

[0374] S1610: The display management service notifies the display composition system to restore the layer stack (LayerStack) of the virtual screen.

[0375] Restoring the layer stack of the virtual screen can be understood as restoring the virtual screen's own invisibility, that is, the content in the virtual screen cannot be displayed in the display area C. For example, when the display management service executes S1510, the display management service can restore the layer stack of the virtual screen by calling setLayerStack().

[0376] Based on this, when the electronic device detects that the electronic device is in the unfolded state, it can exit the collaborative display function by removing the mirror layer and restoring the full-screen display of the electronic device, thereby reducing the waste of device power consumption.

[0377] Optionally, in response to a preset exit operation performed by the user, when the device status management service receives a request to cancel the collaborative display status, the electronic device may execute steps S1603-S1605, S1609-S1610, and S1506.

[0378] The preset exit operation may include one or more of the following: switching a floating window to a floating ball when the window is in a floating window state, switching a mini window to a floating ball when the window is in a mini window state, displaying the content in the floating window in full screen, or closing the floating window. It is understood that after the electronic device exits the collaborative display state. It is understood that during the process of the user performing the preset exit operation, the folded state of the electronic device is changed to the expanded state.

[0379] Understandably, electronic equipment Figure 15 and Figure 16 The settings for the virtual screen in the above embodiments are implemented by the logical screen 2, and the relationship between the logical screen 2 and the virtual screen can be referred to the description in Figure 13 .

[0380] Based on the above corresponding embodiments, the embodiments of the present application further provide an interface display method based on horizontal and vertical screen rotation, which can be referred to the description in Figure 15 . Figure 17

[0381] An exemplary module interaction diagram of another interface display method provided by the embodiments of the present application is shown in Figure 17 . In the corresponding embodiments, the electronic device can include a display screen content module, a display screen rotation module, and a display screen rotation coordination module, and the meanings of any module can be referred to the description in Figure 17 . Figure 4

[0382] It can be understood that the electronic device can detect the rotation direction of the display screen, and the rotation direction of the virtual screen can be obtained by taking the complement of the rotation direction of the display screen. For example, when the rotation direction of the display screen is 90 degrees, the electronic device can obtain 270 degrees by taking the complement of 90 degrees, that is, when the rotation direction of the display screen is 90 degrees, the rotation direction of the virtual screen can be 270 degrees.

[0383] S1701, in response to the operation of starting up or restarting the device, the display screen rotation module registers to listen.

[0384] It can be understood that the display screen rotation module can listen to the change of the rotation direction of the electronic device by registering to listen. For example, the display screen rotation module can register to listen by calling newDisplayRotation().

[0385] S1702, the display screen rotation module notifies the display screen rotation coordination module to set callback function 1.

[0386] The callback function 1 can be used to notify the virtual screen of the rotation condition of the logical screen 1. For example, the display screen rotation module can notify the display screen rotation coordination module to set the callback function 1 by calling setDefaultDisplayRotationchangedCallback().

[0387] S1703, in response to the operation of rotating the electronic device, the display screen content module sends a rotation message to the display screen rotation module.

[0388] ​​The rotation message may include: a rotation angle, such as angle 1. For example, the display screen content module may send a rotation message to the display screen rotation module by calling foldStateChanged().

[0389] S1704: In response to the rotation message, the display screen rotation module updates the rotation angle of the electronic device to angle 1. For example, the display screen rotation module can update the rotation angle of the electronic device by calling updateRotationUnchecked().

[0390] S1705. The display rotation module dispatches angle 1 to the application.

[0391] Exemplarily, the display screen rotation module may distribute angle 1 to the application running in the foreground, so that the application may rotate the displayed content according to angle 1.

[0392] S1706: The display screen rotation module sends a rotation message to the display screen rotation coordination module.

[0393] For example, the display rotation module can notify the display rotation coordination module that the electronic device has rotated by calling onDefaultDisplayRotationChanged.

[0394] S1707. The display screen rotation coordination module notifies the virtual screen in the display screen rotation module through callback function 1 that the rotation angle is angle 1.

[0395] For example, the display screen rotation coordination module notifies the virtual screen in the display screen rotation module through callback function 1 (such as updateRotationAndSendConfigIfChanged()) that the rotation angle is angle 1.

[0396] S1708. The display screen rotation module inverts angle 1 to obtain angle 2.

[0397] For example, when Angle 1 is 90 degrees, Angle 2 can be 270 degrees. That is, when the electronic device rotates 90 degrees, the electronic device can rotate the mirror layer 270 degrees so that the content in the mirror layer can be properly displayed on the virtual screen.

[0398] S1709. The display screen rotation module notifies the window management service to rotate the mirror layer based on angle 2.

[0399] It is understandable that after the window management service receives angle 2, the window management service can implement processing of the mirror layer in S1518.

[0400] Based on this, the electronic device can detect that rotation occurs, and can rotate the mirror layer in the virtual screen by negating the rotation direction, to ensure that the mirror layer can be reasonably displayed in the virtual screen.

[0401] It can be understood that the embodiments of the present application can realize the cooperative display of the applications in the white list, which can include applications capable of being displayed in a floating window state.

[0402] It should be noted that the module names involved in the embodiments of the present application can be defined as other names, as long as the functions of the modules can be realized, and the names of the modules are not specifically limited.

[0403] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data for analysis, stored data, displayed data, etc.) involved in the embodiments of the present application are all information and data authorized by the user or authorized by all parties, and the collection, use and processing of related data need to comply with relevant laws, regulations and standards of relevant countries and regions, and provide corresponding operation portal for user to select authorization or refusal.

[0404] In combination with the description in Figure 15 , a flowchart of an interface display method provided by an embodiment of the present application is shown in Figure 18 . In Figure 18 , an electronic device is taken as a folding screen device as an example for illustration, which does not constitute a limitation on the embodiments of the present application. The folding screen device includes a physical display screen, which includes a first display area and a second display area, and the first display area and the second display area are arranged opposite to each other when the folding screen device is in a folded state.

[0405] As shown in Figure 18 , the interface display method can include the following steps:

[0406] S1801, creating a virtual screen.

[0407] The virtual screen corresponds to the second display area, and the meaning of the virtual screen can be referred to the description in Figure 13-15 .

[0408] S1802, the first display area displays a first interface.

[0409] The first interface includes a first full-screen window corresponding to a first application and a first floating window corresponding to a second application, wherein the folding screen device is in a folded state, and the first floating window includes a first application interface corresponding to the second application.

[0410] The first display area may be the display area B described in the embodiment of the present application, and the second display area may be the display area C described in the embodiment of the present application.

[0411] The first interface may be the interface shown in FIG5C , the first application may be a note application, and the first full-screen window corresponding to the first application may be a note application interface displayed in full screen.

[0412] The second application may be a payment application, and the first floating window corresponding to the second application may be floating window 501 in FIG. 5C . The first application interface corresponding to the second application may be the payment interface in the payment application, such as the application interface in floating window 501, i.e., the payment interface is displayed in floating window 501, and the first application interface does not include the control controls in floating window 501. It is understood that the first application interface is not the interface in the first application.

[0413] S1803. In response to the first operation on the second display area, display a second floating window corresponding to the second application in the first display area, set the display area of ​​the virtual screen to the second display area, and display the first application interface in the second display area through the virtual screen.

[0414] The first operation may be the operation of double-clicking the display area C as described in FIG5C , or may be other operations for entering the collaborative display, see Figure 5-2 to Figure 6-1 Description in .

[0415] The size of the second floating window is smaller than that of the first floating window.

[0416] S1804: In response to a second operation on the second floating window, display the first floating window in the first display area, and display the first application interface in the second display area.

[0417] The second operation may be a click operation on the mini window 506 .

[0418] S1805: In response to the third operation on the first floating window, display a third floating window corresponding to the second application in the first display area, and display the second application interface in the second display area.

[0419] The size of the third floating window is larger than that of the second floating window. The third floating window includes a second application interface corresponding to the second application. The second application interface is different from the first application interface.

[0420] As shown in Figure 6A, the third operation may be an operation of sliding up floating window 601. The third floating window may be floating window 601 in Figure 6C, and the second application interface corresponding to the second application may be the application interface displayed in floating window 601, and the second application interface does not include the control controls in floating window 601.

[0421] Based on this, the folding screen device can not only realize the coordinated display of the content in the window of display area B to display area C, but also in response to the trigger operation performed by the user on display area C, the application interface in the floating window can be updated synchronously with the application interface in display area C, so that the user can view the updated application interface in display area C in real time.
