[0152] Electronic device 100 implements a display function through a GPU, display screen 194, and an application processor, etc. The GPU is a microprocessor for image processing, and is connected to display screen 194 and the application processor. The GPU is used to perform mathematical and geometric calculations for graphics rendering. Processor 110 may include one or more GPUs, which execute program instructions to generate or change display information.

[0153] The display screen 194 is used to display images, videos, etc. The display screen 194 includes a display panel.

[0154] In some embodiments of the present application, when the display panel uses materials such as OLED, AMOLED, FLED, etc., the display screen 194 can be bent, that is, the electronic device 100 can be configured with a foldable display screen. Here, the display screen 194 can be bent means that the display screen can be bent to any angle at a fixed position or any position and can be maintained at that angle. The foldable display screen has two modes: an unfolded state and a folded state. Among them, when the bending angle formed when the foldable display screen is bent is greater than a preset value, it can be regarded as being in the unfolded state, and when the bending angle formed when the foldable display screen is bent is less than the preset value, it can be regarded as being in the folded state. The bending angle can refer to the angle formed at the bending part on the side of the foldable screen that is not used for displaying content. As shown in FIG. 2a, the side of the foldable screen facing the user is used for displaying content, and the bending angle is as shown in the figure. The preset value can be predefined, for example, it can be 90 degrees, 80 degrees, etc. In some embodiments, an angle sensor can be provided at the bending position of the foldable display screen, and the electronic device can detect the bending angle through the angle sensor and determine whether the foldable display screen is in the unfolded state or the folded state according to the bending angle. Exemplarily, referring to Figure 2 FIG. 2a, the display screen 194 can be folded in the middle, and the folded display screen can be divided into a screen A and a screen B. When the electronic device 100 is configured with a foldable display screen and the foldable display screen is in the folded state, it can be regarded that the electronic device 100 provides two display screens. Figure 2

[0155] ​When the foldable display is in the unfolded state, the user interface provided by the operating system of the electronic device can be displayed in full screen. Displaying the user interface in full screen can mean that the user interface occupies the entire display area of ​​the foldable display, or it can mean that the user interface occupies most of the display area of ​​the display. For example, when the foldable display is a notch screen, the middle part of the notch screen displays the user interface, and one or both sides of the edge are black, it can also be regarded as the foldable display screen displaying the user interface in full screen.

[0156] When the foldable display is in a folded state, the electronic device may display the user interface provided by the operating system only on one of the foldable display screens, or may display the user interface provided by the operating system of the electronic device on both display screens of the foldable display screen, and the embodiments of the present application are not limited thereto.

[0157] In some embodiments, when the foldable display changes from an unfolded state to a folded state, the electronic device can change from displaying the user interface in full screen on the foldable display to displaying the user interface on one of the displays on the foldable display.

[0158] In some other embodiments of the present application, the electronic device 100 may be configured with two independent display screens, which are located on two sides of the electronic device 100. Figure 2 2b, which shows an electronic device configured with two display screens (i.e., screen C and screen D in the figure). When the electronic device 100 is configured with two display screens, the two display screens may have the same configuration or different configurations. For example, the two display screens may be made of the same or different materials and may have the same or different screen sizes, for example, one display screen is a 6-inch OLED screen and the other display screen is a 5-inch LCD screen, which is not limited in the embodiments of the present application.

[0159] In the embodiment of the present application, when the electronic device provides two display screens, one of the display screens may be referred to as a first screen, and the other display screen may be referred to as a second screen. Figure 2 2a, screen B can be regarded as the first screen, and screen A can be regarded as the second screen. For example, see Figure 2 For 2b, screen D can be regarded as the first screen and screen C as the second screen.

[0160] The electronic device 100 can realize the shooting function through ISP, camera 193, video codec, GPU, display screen 194 and application processor.

[0161] The ISP is used to process the data fed back by the camera 193. For example, when taking a photo, the shutter is opened, and light passes through the lens and is transmitted to the camera's photosensitive element. The light signal is converted into an electrical signal, and the camera's photosensitive element transmits the electrical signal to the ISP for processing and converts it into an image visible to the naked eye. The ISP can also optimize the noise, brightness, and skin color of the image through algorithms. The ISP can also optimize parameters such as the exposure and color temperature of the shooting scene. In some embodiments, the ISP can be disposed in the camera 193.

[0162] The camera 193 is used to capture still images or videos. An object generates an optical image through the lens and projects it onto the photosensitive element. The photosensitive element can be a charge coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) phototransistor. The photosensitive element converts the light signal into an electrical signal and then transmits the electrical signal to the ISP to be converted into a digital image signal. The ISP outputs the digital image signal to the DSP for processing. The DSP converts the digital image signal into an image signal in a standard format such as RGB or YUV. In some embodiments, the electronic device 100 may include one or N cameras 193, where N is a positive integer greater than 1.

[0163] The digital signal processor is used to process digital signals. In addition to processing digital image signals, it can also process other digital signals. For example, when the electronic device 100 selects a frequency point, the digital signal processor is used to perform Fourier transform on the frequency point energy, etc.

[0164] The video codec is used to compress or decompress digital videos. The electronic device 100 can support one or more video codecs. In this way, the electronic device 100 can play or record videos in multiple encoding formats, such as Moving Picture Experts Group (MPEG) 1, MPEG2, MPEG3, MPEG4, etc.

[0165] The NPU is a neural-network (NN) computing processor. By drawing on the structure of biological neural networks, such as the transmission pattern between human brain neurons, it can quickly process input information and can also continuously learn on its own. Through the NPU, applications such as the intelligent cognition of the electronic device 100 can be realized, such as image recognition, face recognition, speech recognition, text understanding, etc.

[0166] The external memory interface 120 can be used to connect an external memory card, such as a Micro SD card, to implement the storage capacity expansion of the electronic device 100. The external memory card communicates with the processor 110 through the external memory interface 120 to implement the data storage function. For example, files such as music and videos are saved in the external memory card.

[0167] The internal memory 121 can be used to store computer-executable program codes, and the executable program codes include instructions. The internal memory 121 can include a program storage area and a data storage area. Among them, the program storage area can store an operating system, application programs required for at least one function (such as a sound playback function, an image playback function, etc.). The data storage area can store data created during the use of the electronic device 100 (such as audio data, phone book, etc.). In addition, the internal memory 121 can include a high-speed random access memory, and can also include a non-volatile memory, such as at least one disk storage device, a flash memory device, a universal flash storage (UFS), etc. The processor 110 executes various functional applications and data processing of the electronic device 100 by running the instructions stored in the internal memory 121, and / or the instructions stored in the memory provided in the processor.

[0168] The electronic device 100 can implement audio functions through the audio module 170, the speaker 170A, the receiver 170B, the microphone 170C, the headphone interface 170D, and the application processor, etc. For example, music playback, recording, etc.

[0169] The audio module 170 is used to convert digital audio information into an analog audio signal for output, and is also used to convert an analog audio input into a digital audio signal. The audio module 170 can also be used for encoding and decoding audio signals. In some embodiments, the audio module 170 can be disposed in the processor 110, or some functional modules of the audio module 170 can be disposed in the processor 110.

[0170] The speaker 170A, also known as the "loudspeaker", is used to convert an audio electrical signal into a sound signal. The electronic device 100 can listen to music or hands-free calls through the speaker 170A.

[0171] The receiver 170B, also known as the "earpiece", is used to convert an audio electrical signal into a sound signal. When the electronic device 100 answers a call or a voice message, the voice can be listened to by placing the receiver 170B close to the human ear.

[0172] The microphone 170C, also known as a "microphone" or "transmitter", is used to convert sound signals into electrical signals. When making a call or sending a voice message, the user can speak close to the microphone 170C with their mouth to input the sound signal into the microphone 170C. The electronic device 100 can be provided with at least one microphone 170C. In some other embodiments, the electronic device 100 can be provided with two microphones 170C, which can not only collect sound signals but also implement a noise reduction function. In some other embodiments, the electronic device 100 can also be provided with three, four or more microphones 170C to collect sound signals, reduce noise, identify the sound source, and implement functions such as directional recording.

[0173] The headphone jack 170D is used to connect a wired headphone. The headphone jack 170D can be a USB interface 130, or a 3.5mm open mobile terminal platform (OMTP) standard interface, or a cellular telecommunications industry association of the USA (CTIA) standard interface.

[0174] The pressure sensor 180A is used to sense pressure signals and can convert the pressure signals into electrical signals. In some embodiments, the pressure sensor 180A can be disposed on the display screen 194. There are many types of pressure sensors 180A, such as resistive pressure sensors, inductive pressure sensors, capacitive pressure sensors, etc. The capacitive pressure sensor can include at least two parallel plates with conductive materials. When a force acts on the pressure sensor 180A, the capacitance between the electrodes changes. The electronic device 100 determines the intensity of the pressure according to the change in capacitance. When a touch operation acts on the display screen 194, the electronic device 100 detects the intensity of the touch operation according to the pressure sensor 180A. The electronic device 100 can also calculate the position of the touch according to the detection signal of the pressure sensor 180A. In some embodiments, touch operations with the same touch position but different touch operation intensities can correspond to different operation instructions. For example: when a touch operation with a touch operation intensity less than the first pressure threshold acts on the short message application icon, the instruction to view the short message is executed. When a touch operation with a touch operation intensity greater than or equal to the first pressure threshold acts on the short message application icon, the instruction to create a new short message is executed. In some other embodiments of the present application, the pressure sensor 180A can also be disposed on the frame of the electronic device 100. The electronic device 100 can calculate the touch point where the user contacts the electronic device 100 according to the pressure detected by the pressure sensor 180A.

[0175] The gyroscope sensor 180B can be used to determine the motion posture of the electronic device 100. In some embodiments, the angular velocity of the electronic device 100 around three axes (i.e., the x, y, and z axes) can be determined by the gyroscope sensor 180B. The gyroscope sensor 180B can be used for anti-shake shooting. Exemplarily, when the shutter is pressed, the gyroscope sensor 180B detects the shaking angle of the electronic device 100, calculates the distance that the lens module needs to compensate according to the angle, and makes the lens offset the shaking of the electronic device 100 through reverse movement to achieve anti-shake. The gyroscope sensor 180B can also be used for navigation and somatosensory game scenarios. In some embodiments of the present application, the electronic device 100 can determine whether the electronic device is flipped back and forth by the user and whether it is in a vertical posture through the gyroscope sensor 180B.

[0176] The barometric pressure sensor 180C is used to measure barometric pressure. In some embodiments, the electronic device 100 calculates the altitude according to the barometric pressure value measured by the barometric pressure sensor 180C to assist in positioning and navigation.

[0177] The magnetic sensor 180D includes a Hall sensor. The electronic device 100 can use the magnetic sensor 180D to detect the opening and closing of the flip leather case. In some embodiments, when the electronic device 100 is a flip phone, the electronic device 100 can detect the opening and closing of the flip according to the magnetic sensor 180D. Furthermore, according to the detected opening and closing state of the leather case or the flip, features such as automatic unlocking of the flip can be set.

[0178] The acceleration sensor 180E can detect the magnitude of the acceleration of the electronic device 100 in various directions (generally three axes). When the electronic device 100 is stationary, the magnitude and direction of gravity can be detected. It can also be used to identify the posture of the electronic device and is applied to applications such as horizontal and vertical screen switching and pedometers. In some embodiments of the present application, the electronic device 100 can determine whether the electronic device is flipped back and forth by the user and whether it is in a vertical posture through the acceleration sensor 180E.

[0179] The distance sensor 180F is used to measure distance. The electronic device 100 can measure distance through infrared or laser. In some embodiments, in the shooting scene, the electronic device 100 can use the distance sensor 180F to measure distance to achieve rapid focusing.

[0180] The proximity light sensor 180G may include, for example, a light-emitting diode (LED) and a light detector, such as a photodiode. The light-emitting diode may be an infrared light-emitting diode. The electronic device 100 emits infrared light outward through the light-emitting diode. The electronic device 100 uses the photodiode to detect the infrared reflected light from nearby objects. When sufficient reflected light is detected, it can be determined that there is an object near the electronic device 100. When insufficient reflected light is detected, the electronic device 100 may determine that there is no object near the electronic device 100. The electronic device 100 may use the proximity light sensor 180G to detect that the user holds the electronic device 100 close to the ear during a call, so as to automatically turn off the screen to achieve the purpose of power saving. The proximity light sensor 180G can also be used in the holster mode and the pocket mode for automatic unlocking and locking of the screen.

[0181] The ambient light sensor 180L is used to sense the ambient light brightness. The electronic device 100 can adaptively adjust the brightness of the display screen 194 according to the sensed ambient light brightness. The ambient light sensor 180L can also be used to automatically adjust the white balance during photography. The ambient light sensor 180L can also cooperate with the proximity light sensor 180G to detect whether the electronic device 100 is in the pocket to prevent accidental touch.

[0182] The fingerprint sensor 180H is used to collect fingerprints. The electronic device 100 can use the collected fingerprint characteristics to achieve fingerprint unlocking, access application locks, fingerprint photography, fingerprint answering of incoming calls, etc.

[0183] The temperature sensor 180J is used to detect temperature. In some embodiments, the electronic device 100 uses the temperature detected by the temperature sensor 180J to execute a temperature processing strategy. For example, when the temperature reported by the temperature sensor 180J exceeds a threshold, the electronic device 100 reduces the performance of the processor located near the temperature sensor 180J in order to reduce power consumption and implement thermal protection. In other embodiments, when the temperature is lower than another threshold, the electronic device 100 heats the battery 142 to avoid abnormal shutdown of the electronic device 100 caused by low temperature. In other some embodiments, when the temperature is lower than yet another threshold, the electronic device 100 boosts the output voltage of the battery 142 to avoid abnormal shutdown caused by low temperature.

[0184] The touch sensor 180K, also known as the "touch panel". The touch sensor 180K can be disposed on the display screen 194, and the touch sensor 180K and the display screen 194 form a touch screen, also known as the "touch screen". The touch sensor 180K is used to detect touch operations acting on or near it. The touch sensor can transmit the detected touch operation to the application processor to determine the type of touch event. Visual output related to the touch operation can be provided through the display screen 194. In other embodiments, the touch sensor 180K can also be disposed on the surface of the electronic device 100, at a different position from the display screen 194.

[0185] The bone conduction sensor 180M can acquire vibration signals. In some embodiments, the bone conduction sensor 180M can acquire vibration signals of the vibrating bone mass of the human vocal part. The bone conduction sensor 180M can also contact the human pulse to receive blood pressure pulsation signals. In some embodiments, the bone conduction sensor 180M can also be disposed in an earphone to form a bone conduction earphone. The audio module 170 can parse out voice signals based on the vibration signals of the vibrating bone mass acquired by the bone conduction sensor 180M to implement the voice function. The application processor can parse out heart rate information based on the blood pressure pulsation signals acquired by the bone conduction sensor 180M to implement the heart rate detection function.

[0186] The keys 190 include a power-on key, volume keys, etc. The keys 190 can be mechanical keys or touch keys. The electronic device 100 can receive key inputs to generate key signal inputs related to the user settings and function controls of the electronic device 100.

[0187] The motor 191 can generate vibration prompts. The motor 191 can be used for incoming call vibration prompts and can also be used for touch vibration feedback. For example, touch operations on different applications (such as taking pictures, audio playing, etc.) can correspond to different vibration feedback effects. For touch operations on different regions of the display screen 194, the motor 191 can also correspond to different vibration feedback effects. Different application scenarios (such as time reminder, receiving messages, alarm clock, games, etc.) can also correspond to different vibration feedback effects. The touch vibration feedback effect can also support customization.

[0188] The indicator 192 can be an indicator light and can be used to indicate the charging state, power change, and can also be used to indicate messages, missed calls, notifications, etc.

[0189] The SIM card interface 195 is used to connect to a SIM card. The SIM card can be in contact with and separated from the electronic device 100 by being inserted into or removed from the SIM card interface 195. The electronic device 100 can support 1 or N SIM card interfaces, where N is a positive integer greater than 1. The SIM card interface 195 can support Nano SIM cards, Micro SIM cards, SIM cards, etc. Multiple cards can be inserted into the same SIM card interface 195 at the same time. The types of the multiple cards can be the same or different. The SIM card interface 195 can also be compatible with different types of SIM cards. The SIM card interface 195 can also be compatible with external memory cards. The electronic device 100 interacts with the network through the SIM card to implement functions such as calls and data communication. In some embodiments, the electronic device 100 uses an eSIM, that is, an embedded SIM card. The eSIM card can be embedded in the electronic device 100 and cannot be separated from the electronic device 100.

[0190] The software system of the electronic device 100 may adopt a layered architecture, an event-driven architecture, a microkernel architecture, a microservices architecture, or a cloud architecture. In the embodiments of this application, taking the Android system with a layered architecture as an example, the software structure of the electronic device 100 is exemplarily described.

[0191] Figure 3 It is a software structure block diagram of the electronic device 100 in the embodiments of this application.

[0192] The layered architecture divides the software into several layers, and each layer has a clear role and division of labor. The layers communicate with each other through software interfaces. In some embodiments, the Android system is divided into four layers, from top to bottom, namely the application layer, the application framework layer, the Android runtime and system libraries, and the kernel layer.

[0193] The application layer may include a series of application packages.

[0194] Such as Figure 3 shown, the application packages may include applications such as a camera, a gallery, a calendar, a call, a map, a navigation, a WLAN, a Bluetooth, music, a video, a short message, etc.

[0195] The application framework layer provides application programming interfaces (APIs) and programming frameworks for the applications in the application layer. The application framework layer includes some predefined functions.

[0196] Such as Figure 3 shown, the application framework layer may include a window manager, a content provider, a view system, a telephone manager, a resource manager, a notification manager, etc.

[0197] The window manager is used to manage window programs. The window manager can obtain the size of the display screen, determine whether there is a status bar, lock the screen, capture the screen, etc. In the embodiments of this application, the window manager can obtain the sizes of the two display screens provided by the electronic device 100 and uniformly manage the content displayed on the two display screens.

[0198] The content provider is used to store and obtain data and make this data accessible to applications. The data may include videos, images, audio, dialed and answered calls, browsing history and bookmarks, a phone book, etc.

[0199] The view system includes visible controls, such as controls for displaying text, controls for displaying pictures, etc. The view system can be used to build applications. The display interface can be composed of one or more views. For example, a display interface including a short message notification icon may include a view for displaying text and a view for displaying pictures.

[0200] The telephone manager is used to provide the communication function of the electronic device 100. For example, the management of call status (including answering, hanging up, etc.).

[0201] The resource manager provides various resources for applications, such as localized strings, icons, pictures, layout files, video files, and so on.

[0202] The notification manager enables applications to display notification information in the status bar. It can be used to convey message types that inform, and can automatically disappear after a short stay without user interaction. For example, the notification manager is used to inform that the download is completed, message reminders, etc. The notification manager can also be a notification that appears in the system top status bar in the form of a chart or scroll bar text, such as the notification of a background-running application, and can also be a notification that appears on the screen in the form of a dialog window. For example, it prompts text information in the status bar, emits a prompt sound, the electronic device vibrates, the indicator light flashes, etc.

[0203] Android Runtime includes the core libraries and the virtual machine. Android runtime is responsible for the scheduling and management of the Android system.

[0204] The core libraries contain two parts: one part is the functional functions that the Java language needs to call, and the other part is the core libraries of Android.

[0205] The application layer and the application framework layer run in the virtual machine. The virtual machine executes the Java files of the application layer and the application framework layer as binary files. The virtual machine is used to perform functions such as the management of object life cycles, stack management, thread management, security and exception management, and garbage collection.

[0206] The system libraries can include multiple functional modules. For example: surface manager, Media Libraries, 3D graphics processing libraries (such as: OpenGL ES), 2D graphics engines (such as: SGL), etc.

[0207] The surface manager is used to manage the display subsystem and provides the fusion of 2D and 3D layers for multiple applications.

[0208] The media libraries support the playback and recording of multiple common audio and video formats, as well as static image files, etc. The media libraries can support multiple audio and video coding formats, such as: MPEG4, H.264, MP3, AAC, AMR, JPG, PNG, etc.

[0209] The 3D graphics processing library is used to implement 3D graphics drawing, image rendering, synthesis, and layer processing, etc.

[0210] The 2D graphics engine is a graphics engine for 2D drawing.

[0211] The kernel layer is the layer between hardware and software. The kernel layer at least includes a display driver, a camera driver, an audio driver, and a sensor driver.

[0212] The following exemplarily describes the working processes of the software and hardware of the electronic device 100 in combination with the capture and photographing scenario.

[0213] When the touch sensor 180K receives a touch operation, the corresponding hardware interrupt is sent to the kernel layer. The kernel layer processes the touch operation into a raw input event (including information such as touch coordinates and the timestamp of the touch operation). The raw input event is stored in the kernel layer. The application framework layer obtains the raw input event from the kernel layer and identifies the control corresponding to the input event. Taking the touch operation as a touch click operation and the control corresponding to the click operation as the control of the camera application icon as an example, the camera application calls the interface of the application framework layer to start the camera application, and then starts the camera driver by calling the kernel layer, and captures a static image or video through the camera 193.

[0214] Based on Figure 1 the electronic device 100 shown, the embodiments of the present application provide a display method. The electronic device 100 in the embodiments of the present application includes two display screens: a first screen and a second screen. For example, referring to Figure 2 FIG. 2a, the first screen may be screen B, and the second screen may be screen A. Another example, referring to Figure 2 FIG. 2b, the first screen may be screen D, and the second screen may be screen C.

[0215] When implementing the display method of the embodiments of the present application, the user can trigger the second screen to display the content that the user hopes to see by using the interaction method of turning the electronic device forward and backward, which is simple to operate and can improve the user experience. Turning the electronic device forward and backward means swapping the relative positions between the first screen and the second screen and the user. For example, referring to Figure 2 FIG. 2a, when the foldable display screen is in the folded state, the first screen (i.e., screen B) faces the user, and the second screen (i.e., screen A) faces away from the user. After the user turns the electronic device forward and backward, the first screen faces away from the user, and the second screen faces the user. Another example, referring to Figure 2 FIG. 2b, the first screen (i.e., screen D) faces the user, and the second screen (i.e., screen C) faces away from the user. After the user turns the electronic device forward and backward, the first screen faces away from the user, and the second screen faces the user. Here, when the user holds the electronic device, if the user can see the content displayed on the screen, it can be regarded that the screen faces the user; if the user cannot see the content displayed on the screen, it can be regarded that the screen faces away from the user.

[0216] Specifically, when the electronic device is configured with a foldable display screen and the foldable display screen is in a folded state, or when the electronic device is configured with two independent display screens, the user can trigger the electronic device to display corresponding content on the second screen by operating the electronic device to flip it back and forth, combining the current position where the electronic device is located, the currently launched application, etc. The following describes the display method provided by the embodiments of the present application in different cases.

[0217] (1) The user triggers the electronic device to display corresponding content on the second screen by operating the electronic device to flip it back and forth, combining the currently launched application.

[0218] In the first case, the currently launched application on the electronic device can be a reading application, a camera application, etc. The following describes the display method provided by the embodiments of the present application in combination with specific application scenarios.

[0219] Application Scenario 1: The electronic device 100 launches a reading application and displays the user interface provided by the reading application on the first screen. The user can trigger the electronic device 100 to display the user interface provided by the reading application on the second screen by operating the electronic device 100 to flip it back and forth. In the embodiments of the present application, the reading application can be referred to as the first application.

[0220] A reading application refers to an application that provides information such as text and pictures for users to read. The pictures can include static pictures and dynamic pictures. For example, reading applications can include: Kindle, WeChat Reading, Douban Reading, Weibo, Zhihu, JianShu, or Toutiao, etc.

[0221] Exemplarily, referring to Figure 4 Figure 4a, which shows the user interface 10 provided by the reading application (such as Kindle) displayed on the first screen when the electronic device 100 launches the reading application. In the example shown in Figure 4a, the first screen faces the user and the second screen faces away from the user. The user interface 10 may include: text 101 provided by the reading application, a control 102 for returning to the previous level, a comment input box 103, a favorite control 104, a sharing control 105, etc. In some embodiments, the user interface 10 may further include a status bar 106. The status bar 106 may include one or more of the following: the name of the operator (such as China Mobile), a Wi-Fi icon, signal strength, time, a battery icon, remaining battery power, an alarm icon (not shown in the figure), or a Bluetooth icon (not shown in the figure), etc. In the embodiments of the present application, the user interface 10 displayed by the electronic device on the first screen can be referred to as the first user interface.

[0222] In some embodiments, when the electronic device 100 is configured with a foldable display screen, Figure 4In the example shown in 4a, the foldable display screen is in a folded state. This folded state can be transformed from the unfolded state. When the foldable display screen is in the unfolded state, the foldable display screen can display the user interface provided by the reading application, and the user interface is displayed on both the first screen and the second screen. Moreover, the content displayed on the user interface includes the content of the user interface displayed on the first screen when the foldable display screen is in the folded state (such as the content included in user interface 10). In some embodiments, when the foldable display screen is in the unfolded state, the user interface can be displayed full screen. In some embodiments, the user interface displayed when the foldable display screen is in the unfolded state is an enlarged version of the user interface displayed on the first screen when the foldable display screen is in the folded state. In other embodiments, the user interface displayed when the foldable display screen is in the unfolded state not only includes the content in the user interface displayed on the first screen when the foldable display screen is in the folded state, but also can include other content, such as more text, controls, etc. In the embodiments of the present application, the user interface displayed when the foldable display screen is in the unfolded state can be referred to as the third user interface.

[0223] In some embodiments, when the electronic device 100 displays the user interface provided by the reading application on the first screen, the second screen can be in a black screen state or can display content. The second screen being in a black screen state can mean that the electronic device 100 turns off the power supply of the second screen, or can mean that the second screen displays a black screen, and there is no limitation here.

[0224] In the embodiments of the present application, the user can flip the electronic device 100 back and forth to swap the relative positions between the second screen and the first screen of the electronic device 100 and the user. For example, the user can flip the electronic device 100 in the direction of the arrow shown in Figure 4 That is to say, after the user flips the electronic device 100 back and forth, the second screen faces the user and the first screen faces away from the user. In response to the user's operation of flipping the electronic device back and forth, the electronic device 100 can display the user interface provided by the reading application on the second screen.

[0225] In a specific implementation, when the electronic device 100 is in the folded state, the electronic device 100 can detect whether the electronic device 100 is flipped back and forth through one or more of a gyroscope sensor, an acceleration sensor, and a gravity sensor. For example, the gyroscope sensor can detect the angle of clockwise or counterclockwise rotation of the electronic device along the Y-axis of its plane. If the rotation angle is greater than a first value (such as 150 degrees or 160 degrees), it is determined that the electronic device 100 is flipped back and forth. Here, the Y-axis of the electronic device along its plane refers to the direction from the bottom of the first screen along the vertical direction of the screen to the top of the first screen, and reference can be made to Figure 2The Y-axis shown in [reference]. Also, for example, to prevent the electronic device 100 from misinterpreting that it has been flipped when the user holds the electronic device 100 and adjusts its orientation (e.g., from facing east to facing west when the user holds the electronic device 100), the acceleration sensor can also be used to detect the acceleration of the electronic device along its Z-axis. When the above rotation angle is greater than a first value and the acceleration is less than a second value, it is determined that the electronic device 100 has been flipped forward and backward. Here, the Z-axis refers to the direction perpendicular to the plane where the first screen is located, and reference can be made to Figure 2 the Z-axis shown in [reference].

[0226] In the embodiments of the present application, one or more of the gyroscope sensor, acceleration sensor, and gravity sensor of the electronic device can continuously and real-time monitor the posture of the electronic device.

[0227] Exemplarily, refer to Figure 4 Figure 4b, which shows the user interface 20 provided by the reading application displayed on the second screen after the electronic device 100 detects the operation of the user flipping the electronic device forward and backward. As shown in Figure 4b, each interface element in the user interface 20 is the same as the user interface 10 in Figure 4a, and the relevant description in Figure 4a can be referred to. In the embodiments of the present application, the user interface 20 displayed on the second screen after the electronic device 100 is flipped forward and backward can be referred to as the second user interface.

[0228] It can be understood that in some embodiments, the configurations of the first screen and the second screen may be different. For example, the screen sizes of the first screen and the second screen may be different. The screen size can include the area of the screen, the ratio of the screen width (width) to the height (height), etc. When the screen sizes of the first screen and the second screen are different, compared with the user interface 10 provided by the reading application displayed on the first screen, when the electronic device displays the user interface 20 provided by the reading application on the second screen, the arrangement manner of the interface elements in the user interface 20 can be adaptively adjusted to be more in line with the user's habits and look more beautiful. For example, if the screen size of the second screen is smaller than that of the first screen, the number of characters provided in the interface 20 displayed on the second screen can be reduced, or the interface elements in the user interface 20 displayed on the second screen can be scaled down proportionally. In practical applications, the adaptive adjustment of the interface elements displayed on the second screen can also include adjusting the spacing between the interface elements, the display positions of the interface elements, etc., and the embodiments of the present application do not limit this.

[0229] In some embodiments, when the electronic device 100 displays the user interface 20 on the second screen in response to the user's operation of flipping the electronic device back and forth, it can also display the user interface 20 in a manner suitable for the user to read. Specifically, the electronic device 100 can adjust the background color of the user interface 20 to a dark color (e.g., black) and switch the interface elements in the interface 20 to a suitable color (e.g., white). Such a display method can save power and avoid glare during reading, facilitating the user's reading. Exemplarily, reference can be made to Figure 4 4b of

[0230] In the embodiments of the present application, when the electronic device 100 displays the user interface 20 on the second screen in response to the user's operation of flipping the electronic device back and forth, the first screen may not display any content, such as becoming a black screen state, or may continue to display the user interface 10, which is not limited here. The first screen becoming a black screen state may mean that the electronic device 100 stops supplying power to the first screen, or may mean that the first screen displays a black screen, which is not limited here. In some embodiments, when the first screen continues to display the user interface 10, the electronic device 100 can receive and respond to the input user operations on the user interface 10. In other embodiments, when the first screen continues to display the user interface 10, the user interface 10 is locked, that is, the electronic device 100 cannot receive and respond to the input user operations on the user interface 10, which can prevent the user from accidentally triggering some functions of the electronic device 100 on the first screen.

[0231] In some embodiments, after the electronic device 100 displays the user interface 20 on the second screen in response to the user's operation of flipping the electronic device back and forth, the user can also flip the electronic device 100 back and forth again, so that the electronic device 100 displays the user interface 10 on the first screen. For example, the user can flip the electronic device 100 again in the arrow direction shown in Figure 4 . That is to say, after the user flips the electronic device 100 back and forth again, the first screen faces the user and the second screen faces away from the user. Exemplarily, refer to Figure 4 4a of

[0232] ByFigure 4 As shown in the example, when the electronic device displays the user interface provided by the reading application on the first screen, the user can trigger the electronic device to display the user interface provided by the reading application on the second screen by operating the electronic device to flip it forward and backward. In addition, the second screen can display the user interface in a form suitable for the user to read, enhancing the user experience.

[0233] Application scenario 2: The electronic device 100 currently launches the camera application, and the first screen displays the camera interface. The user can trigger the electronic device 100 to display the self-timer interface on the second screen by operating the electronic device 100 to flip it forward and backward.

[0234] The camera application can be pre-installed on the electronic device 100 or can be downloaded and installed by the electronic device 100 through the network, and there is no limitation here.

[0235] In the embodiment of the present application, the electronic device 100 can be provided with a set of cameras above the first screen and the second screen respectively, or can be provided with a set of cameras only above the first screen or the second screen. A set of cameras can include one or more cameras.

[0236] Exemplarily, referring to Figure 5 Figure 5a, which shows that the electronic device 100 currently launches the camera application (for example, the camera application pre-installed on the electronic device 100), and the camera interface 30 displayed on the first screen. In the example shown in Figure 5a, the first screen faces the user and the second screen faces away from the user. Exemplarily, the camera interface 30 may include: an echo control 201 for the captured image, a shooting control 202, a control 203 for switching the camera, a shooting mode menu 204, a viewfinder 205, and some other controls such as a control 206A for starting the intelligent object recognition function, a control 206B for turning on / off the flash, a control 206C for turning on / off the dynamic picture shooting function, a control 206D for adjusting the tone, and a setting control 206E. Among them:

[0237] The echo control 201 for the captured image can be used to display the image captured by the electronic device 100 most recently, and can also monitor the user operation for opening the album. The electronic device 100 can detect the user operation (such as a click operation) acting on the control 201, respond to this operation, and in response to this user operation, open the album application and display the saved pictures.

[0238] The shooting control 202 can monitor the user operation for shooting an image. The electronic device can detect the user operation (such as a click operation) acting on the shooting control 202, and in response to this user operation, determine the captured picture, save the picture and display the picture in the control 201. That is to say, the user can click the shooting control 202 to shoot an image.

[0239] The control 203 for switching the camera can monitor user operations for switching the camera. The electronic device 100 can detect a user operation acting on the control 203 (such as a click operation), and switch the currently activated camera in response to the user operation. For example, turn off the camera above the second screen and activate the camera above the first screen.

[0240] The shooting mode menu 204 can display one or more shooting mode options. The shooting mode options can be implemented as icons, text, or other forms. As shown in 5a, the shooting mode options in the shooting mode menu 204 can include: an option for the large aperture mode, an option for the night scene mode, an option for the portrait mode, an option for the photo shooting mode, an option for the video recording mode, an option for the professional mode, etc.

[0241] The viewfinder 205 can be used to display the image acquired by the camera. The electronic device 100 can refresh the display content therein in real time. Among them, the image in the viewfinder 205 is the picture in the direction of the second screen collected by the camera set above the second screen of the electronic device 100.

[0242] In some embodiments, the photographing interface 30 may further include a hidden navigation bar. The navigation bar may include a back key, a home screen key, and a multitasking key.

[0243] In the embodiments of the present application, the photographing interface 30 displayed by the electronic device on the first screen can be referred to as the first preview screen.

[0244] In some embodiments, when the electronic device 100 is configured with a foldable display screen, Figure 5 In the example shown in 5a, the foldable display screen is in a folded state. This folded state can be transformed from the unfolded state. When the foldable display screen is in the unfolded state, the foldable display screen can display the user interface provided by the camera application, and this user interface is displayed on both the first screen and the second screen. And, this user interface includes the picture in the direction of the second screen collected by the camera above the second screen. In some embodiments, when the foldable display screen is in the unfolded state, the user interface provided by the camera application can be displayed full screen. In the embodiments of the present application, the user interface displayed when the foldable display screen is in the unfolded state can be referred to as the third preview screen.

[0245] In some embodiments, when the electronic device 100 displays the photographing interface provided by the camera application on the first screen, the second screen can be in a black screen state or can display content. The second screen being in a black screen state can mean that the electronic device 100 turns off the power supply of the second screen, or can mean that the second screen displays a black picture, which is not limited here.

[0246] In the embodiments of the present application, the user can flip the electronic device 100 back and forth to exchange the relative positions between the second screen and the first screen of the electronic device 100 and the user. For example, the user can flip the electronic device 100 in the direction of the arrow shown in Figure 5 . After the user flips the electronic device 100 back and forth, the second screen faces the user and the first screen faces away from the user. Here, for how the electronic device 100 detects the operation of the user flipping the electronic device back and forth, reference can be made to the relevant description in Application Scenario 1.

[0247] In Application Scenario 2, a set of cameras provided above the second screen of the electronic device 100 can continuously work to capture images. After the user flips the electronic device 100 back and forth, since the second screen faces the user, a set of cameras provided above the second screen at this time capture an image of the user. The electronic device 100 can display the image of the user captured by the set of cameras above the second screen on the second screen, that is, display a self-portrait interface on the second screen. That is to say, before the user flips the electronic device 100 back and forth, the image captured by the set of cameras above the second screen is displayed on the first screen, and after the user flips the electronic device 100 back and forth, the image captured by this set of cameras is displayed on the second screen.

[0248] In the embodiments of the present application, the configurations of the first screen and the second screen may be the same or different. For example, the screen sizes of the first screen and the second screen may be the same or different. When the screen sizes of the first screen and the second screen are the same, when the electronic device 100 displays a self-portrait interface on the second screen, the arrangement manner of the interface elements in this self-portrait interface can be the same as that of the shooting interface displayed on the first screen. When the screen sizes of the first screen and the second screen are different, compared with displaying a shooting interface on the first screen, when the electronic device 100 displays a self-portrait interface on the second screen, the arrangement manner of the interface elements in the self-portrait interface can be adaptively adjusted to be more in line with the user's habits and display beautifully.

[0249] Exemplarily, referring to Figure 5 5b, which shows a self-portrait interface 40 displayed on the second screen after the electronic device 100 detects the operation of the user flipping the electronic device back and forth when the aspect ratio of the second screen is smaller than that of the first screen. As Figure 5As shown in Figure 5b, the self-timer interface 40 may include: a captured image echo control 201, a shooting control 202, a control 203 for switching cameras, a shooting mode menu 204, a viewfinder 205, a captured image echo area 207, and some other controls such as a control 206A for starting the intelligent object recognition function, a control 206B for turning on / off the flash, a control 206C for turning on / off the dynamic picture shooting function, a control 206D for adjusting the color tone, and a settings control 206E. Among them, the picture displayed in the viewfinder 205 is captured by a set of cameras arranged above the second screen and may include the user's face picture. The captured image echo area 207 is used to display the images captured by the electronic device 100 previously. In some embodiments, the self-timer interface 40 may further include a hidden navigation bar. In the embodiments of the present application, the user interface (such as the self-timer interface 40) displayed on the second screen after the electronic device 100 is flipped forward and backward may be referred to as the second preview screen.

[0250] As can be seen from the comparison between Figure 5a and Figure 5b, when the aspect ratio of the second screen is smaller than that of the first screen, after the user flips the electronic device forward and backward, when the electronic device 100 displays the self-timer interface on the second screen, the arrangement of each element in the self-timer interface is adjusted. The adjustment includes reducing the spacing between each interface element and increasing the captured image echo area 207, etc. Not limited to the arrangement shown in Figure 5b, in practical applications, when the electronic device 100 displays the self-timer interface on the second screen, it can also adjust the display ratio of each element in the self-timer interface, the display position between interface elements, add or reduce interface elements, etc. The embodiments of the present application do not limit this.

[0251] In some embodiments, after the electronic device 100 responds to the operation of the user flipping the electronic device forward and backward, while displaying the self-timer interface 40 on the second screen, it can also switch the shooting mode of the camera application to the portrait mode. In the portrait mode, the face picture displayed in the viewfinder 205 of the self-timer interface 40 is processed by the electronic device 100, and the face picture can carry one or more of the depth of field effect, background blurring effect, and portrait beautification effect. Among them, the face picture carrying the depth of field effect means blurring the background to highlight the shooting object (i.e., the face), the face picture carrying the background blurring effect means making the depth of field shallower so that the focus of the picture is concentrated on the face, and the portrait beautification effect may include but is not limited to whitening, face slimming, skin smoothing, pupil enlargement, etc.

[0252] Exemplarily, refer to Figure 5 Figure 5b. When the self-timer interface 40 is displayed on the second screen, the electronic device 100 switches the shooting mode of the camera application to the portrait mode.

[0253] In the embodiments of the present application, when the electronic device 100 displays the selfie interface 40 on the second screen in response to the user's operation of flipping the electronic device back and forth, the first screen may not display any content, for example, it may become a black screen state, or it may continue to display the camera interface 30, which is not limited here. The first screen becoming a black screen state may mean that the electronic device 100 stops supplying power to the first screen, or it may mean that the first screen displays a black screen, which is not limited here. In some embodiments, when the first screen continues to display the camera interface 30, the electronic device 100 may receive and respond to the input user operations on the camera interface 30. In other embodiments, when the first screen continues to display the camera interface 30, the camera interface 30 is locked, that is, the electronic device 100 cannot receive and respond to the input user operations on the camera interface 30, which can prevent the user from accidentally triggering some functions of the electronic device 100 on the first screen.

[0254] In some embodiments, after the electronic device 100 displays the selfie interface 40 on the second screen in response to the user's operation of flipping the electronic device back and forth, the user can also flip the electronic device 100 back and forth again, so that the electronic device 100 displays the camera interface 30 on the first screen. Exemplarily, referring to Figure 5 Figure 5a, when detecting the user's operation of flipping the electronic device 100 back and forth again, the electronic device 100 can display the camera interface 30 on the first screen. When the electronic device displays the camera interface 30 on the first screen, the second screen may not display any content, for example, it may become a black screen state, or it may continue to display the selfie interface 40, which is not limited here.

[0255] Through Figure 5 the above examples, it can be seen that when the electronic device displays the camera interface on the first screen, the user can trigger the electronic device to display the selfie interface on the second screen by operating the electronic device to flip it back and forth. In addition, the electronic device can also switch the shooting mode of the camera application to the portrait mode, which is simple to operate and can meet the user's selfie needs, improving the user experience.

[0256] Application scenario 3: The electronic device 100 currently launches a video call application, and the first screen displays a video call interface. The user can trigger the electronic device 100 to display the video call interface on the second screen by operating the electronic device 100 to flip it back and forth.

[0257] The video call application refers to an application that enables two or more parties to have a video call. For example, the video call application may include: WeChat, FaceTime, or Skype, etc. In the embodiments of the present application, the video call application can be referred to as the first application.

[0258] In application scenario 3, a set of cameras are respectively arranged above the first screen and the second screen of the electronic device 100. In the embodiments of the present application, the camera arranged above the first screen can be referred to as the first camera, and the camera arranged above the second screen can be referred to as the second camera.

[0259] Exemplarily, referring to Figure 6 Figure 6a, which shows that the electronic device 100 currently launches a video call application, and the video call interface 50 displayed on the first screen. In the example shown in Figure 6a, the first screen faces the user, and the second screen faces away from the user. Exemplarily, the video call interface 50 may include: a shooting screen display area 301, a display area 302 for the other party's screen, a control 303 for switching the camera, a hang-up control 304, a mute control 305, etc. In some embodiments, the display area 302 for the other party's screen is floatingly displayed above the shooting screen display area 301, covering part of the content of the shooting screen display area 301. In other embodiments, the area 302 and the area 301 shown in Figure 6a can be interchanged, that is, the shooting screen display area 301 can be floatingly displayed above the display area 302 for the other party's screen, covering part of the content of the display area 302 for the other party's screen. Among them, the user screen displayed in the shooting screen display area 301 can be captured by a set of cameras arranged above the first screen. The display area 302 for the other party's screen is used to display the screen of the other party in the video call, and the screen of the other party in the video call is the screen of the other party who has established a video call connection with the user. In the embodiments of the present application, the video call interface 50 displayed by the electronic device on the first screen can be referred to as the first user interface of the first application.

[0260] In some embodiments, when the electronic device 100 is configured with a foldable display screen, Figure 6 in the example shown in Figure 6a of the present application, the foldable display screen is in a folded state. This folded state can be transformed from the unfolded state. When the foldable display screen is in the unfolded state, the foldable display screen can display the user interface provided by the video call application, and this user interface is displayed on both the first screen and the second screen. Moreover, the user interface is an enlarged version of the user interface (such as the video call interface 50) displayed on the first screen when the foldable display screen is in the folded state. In some embodiments, when the foldable display screen is in the unfolded state, the foldable display screen can display the user interface provided by the video call application in full screen. In the embodiments of the present application, the user interface displayed when the foldable display screen is in the unfolded state can be referred to as the third user interface of the first application.

[0261] In some embodiments, when the electronic device 100 displays a video call interface on the first screen, the second screen can be in a black screen state or can display content. The second screen being in a black screen state can mean that the electronic device 100 turns off the power supply of the second screen, or can mean that the second screen displays a black screen, which is not limited here.

[0262] In the embodiments of the present application, the user can flip the electronic device 100 back and forth to swap the relative positions between the second screen and the first screen of the electronic device 100 and the user. For example, the user can flip the electronic device 100 in the direction of the arrow shown in Figure 6 . After the user flips the electronic device 100 back and forth, the second screen faces the user and the first screen faces away from the user. Here, for how the electronic device 100 detects the operation of the user flipping the electronic device back and forth, reference can be made to the relevant description in Application Scenario 1.

[0263] In Application Scenario 3, after the electronic device 100 detects the operation of the user flipping the electronic device 100 back and forth, it can turn off a set of cameras arranged above the first screen and activate a set of cameras arranged above the second screen. After the user flips the electronic device 100 back and forth, since the second screen faces the user, therefore, after the set of cameras arranged above the second screen is activated, the user's picture is captured. The electronic device 100 can display the user picture captured by the set of cameras above the second screen in the second screen and display a video call interface in the second screen.

[0264] In the embodiments of the present application, the configurations of the first screen and the second screen may be the same or different. For example, the screen sizes of the first screen and the second screen may be the same or different. When the screen sizes of the first screen and the second screen are the same, when the electronic device 100 displays a video call interface in the second screen, the arrangement manner of the interface elements in the video call interface can be the same as that of the video call interface displayed in the first screen. When the screen sizes of the first screen and the second screen are different, compared with displaying a video call interface in the first screen, when the electronic device 100 displays a video call interface in the second screen, the arrangement manner of the interface elements in the video call interface can be adaptively adjusted to be more in line with the user's habits and display beautifully.

[0265] Exemplarily, referring to Figure 6 6b of, which shows a video call interface 60 displayed in the second screen after the electronic device 100 detects the operation of the user flipping the electronic device back and forth when the aspect ratio of the second screen is smaller than that of the first screen. As Figure 6As shown in 6b, the video call interface 60 may include: a captured image display area 301, an opposite party's image display area 302, a control 303 for switching the camera, a hang-up control 304, a mute control 305, etc. The opposite party's image display area 302 and the captured image display area 301 do not obscure each other. Among them, the user image displayed in the captured image display area 301 is obtained by a set of cameras arranged above the second screen. In the embodiment of the present application, the user interface (such as the video call interface 60) displayed on the second screen after the electronic device 100 is flipped forward and backward can be referred to as the second user interface of the first application.

[0266] Comparing 6a and 6b, it can be seen that when the aspect ratio of the second screen is smaller than that of the first screen, after the user flips the electronic device forward and backward, when the electronic device 100 displays the video call interface on the second screen, the arrangement of each element in the video call interface is adjusted. The adjustment includes reducing the image in the captured image display area 301, reducing the display ratios of the controls 303, 304, and 305, adjusting the relative positions between the opposite party's image display area 302 and the captured image display area 301, etc. Not limited to the arrangement shown in 6b, in practical applications, when the electronic device 100 displays the video call interface on the second screen, it can also add or reduce interface elements, etc. The embodiment of the present application does not limit this.

[0267] In some embodiments, when the electronic device 100 displays the video call interface on the second screen in response to the user's operation of flipping the electronic device forward and backward, the first screen may not display any content, such as turning into a black screen and entering a black screen state.

[0268] In some embodiments, after the electronic device 100 displays the video call interface 60 on the second screen in response to the user's operation of flipping the electronic device forward and backward, the user can also flip the electronic device 100 forward and backward again, so that the electronic device 100 displays the video call interface 50 on the first screen. Exemplarily, referring to Figure 6 6a, when detecting the user's operation of flipping the electronic device 100 forward and backward again, the electronic device 100 can display the video call interface 50 on the first screen.

[0269] Through Figure 6 the examples, it can be seen that when the electronic device displays the video call interface on the first screen, the user can trigger the electronic device to display the video call interface on the second screen by operating to flip the electronic device forward and backward. When the video call interface is displayed on the second screen, the video call interface will be adapted to the size of the second screen for display, which is simple to operate and can improve the user experience.

[0270] Application Scenario 4: The electronic device is currently running a ride-hailing application, and the user places an order through this ride-hailing application. The user can trigger the electronic device 100 to display order information on the second screen by operating the front-back flipping of the electronic device 100.

[0271] Through a ride-hailing application, a user can post a ride-hailing message, that is, place an order. A driver matching the ride-hailing message can accept the order and send the user to the destination. Ride-hailing applications can include, but are not limited to: Didi Chuxing, Uber, Lyft, etc. In the embodiments of the present application, the ride-hailing application can be referred to as the first application.

[0272] When the electronic device 100 is running a ride-hailing application, the user can place an order through this ride-hailing application. Exemplarily, refer to Figure 7 Figure 7a, which shows the user interface 70 displayed on the first screen when the user places an order through a ride-hailing application. In the example shown in Figure 7a, the first screen faces the user, and the second screen faces away from the user. The user interface 70 can include: a plurality of controls 401 for selecting the vehicle type, a pick-up point input control 402, a drop-off point input control 403, a call express car control 404, and some other interface elements. In some embodiments, the user interface 70 may further include a status bar. In some embodiments, the user interface 70 may further include a navigation bar. After the user enters ride-hailing information in the user interface shown in Figure 7a, the user can click the call express car control 404 to place an order. After placing the order, a driver matching the ride-hailing information entered by the user can accept the order.

[0273] In some embodiments, when the electronic device 100 is configured with a foldable display screen, Figure 7 in the example shown in Figure 7a of the foldable display screen is in a folded state. This folded state can be transformed from the unfolded state. When the foldable display screen is in the unfolded state, the foldable display screen can display the user interface provided by the ride-hailing application, and the user interface is displayed on both the first screen and the second screen. Moreover, the content displayed on the user interface includes the content of the user interface displayed on the first screen when the foldable display screen is in the folded state (for example, the content included in the user interface 70). In some embodiments, when the foldable display screen is in the folded state, it can full-screen display the user interface provided by the ride-hailing application. In some embodiments, the user interface displayed when the foldable display screen is in the unfolded state is an enlarged user interface displayed on the first screen when the foldable display screen is in the folded state. In other embodiments, the user interface displayed when the foldable display screen is in the unfolded state not only includes the content in the user interface displayed on the first screen when the foldable display screen is in the folded state, but may also include other content, such as more text, controls, etc. In the embodiments of the present application, the user interface displayed when the foldable display screen is in the unfolded state can be referred to as the third user interface.

[0274] Exemplarily, referring to Figure 7 7b, after the user places an order, the electronic device 100 can exit the display of the user interface provided by the ride-hailing application in response to the user's operation and display the user interface 80 provided by other applications (such as a reading application). Here, after the electronic device 100 exits the display of the user interface provided by the ride-hailing application, the ride-hailing application continues to run in the background of the electronic device 100. In the embodiments of the present application, the user interface 80 displayed by the electronic device on the first screen can be referred to as the first user interface.

[0275] In some embodiments, when the electronic device 100 displays the user interface as shown in 7b on the first screen, the second screen can be in a black screen state or can display content. The second screen being in a black screen state can mean that the electronic device 100 turns off the power supply of the second screen, or can mean that the second screen displays a black screen, which is not limited here.

[0276] When the electronic device 100 displays the user interface 80 as shown in 7b on the first screen, the user can flip the electronic device 100 back and forth to swap the relative positions between the second screen and the first screen of the electronic device 100 and the user. For example, the user can flip the electronic device 100 in the arrow direction shown in Figure 7 . That is to say, after the user flips the electronic device 100 back and forth, the second screen faces the user and the first screen faces away from the user. In response to the user's operation of flipping the electronic device back and forth, the electronic device 100 can display the order information of the order placed by the user through the ride-hailing application on the second screen. The order information can include at least one of the following: whether it has been accepted, the acceptor, the acceptor's contact information, the license plate of the accepting vehicle, the time when the accepting vehicle arrives at the boarding point, etc. Exemplarily, referring to Figure 7 7c, which shows the order information displayed on the second screen after the electronic device 100 detects the user's operation of flipping the electronic device back and forth. In the embodiments of the present application, the user interface (such as the user interface shown in 7c) displayed on the second screen after the electronic device 100 is flipped back and forth can be referred to as the second user interface.

[0277] In an embodiment of the present application, when the electronic device 100 displays order information on the second screen in response to the user's operation of flipping the electronic device back and forth, the first screen may not display any content, for example, it may become a black screen state, or it may continue to display the user interface 80, which is not limited here. The first screen becoming a black screen state may mean that the electronic device 100 stops supplying power to the first screen, or it may mean that the first screen displays a black screen, which is not limited here. In some embodiments, when the first screen continues to display the user interface 80, the electronic device 100 may receive and respond to the input user operations on the user interface 80. In other embodiments, when the first screen continues to display the user interface 80, the user interface 80 is locked, that is, the electronic device 100 cannot receive and respond to the input user operations on the user interface 80, which can prevent the user from accidentally triggering some functions of the electronic device 100 on the first screen.

[0278] In some embodiments, after the electronic device 100 displays order information on the second screen in response to the user's operation of flipping the electronic device back and forth, the user can also flip the electronic device 100 back and forth again, so that the electronic device 100 displays the user interface 80 on the first screen. Exemplarily, referring to Figure 7 Figure 7b, when detecting the user's operation of flipping the electronic device 100 back and forth again, the electronic device 100 can display the user interface 80 on the first screen. When the electronic device 100 displays the user interface 80 on the first screen, the second screen may not display any content, for example, it may become a black screen state, or it may continue to display the order information, which is not limited here.

[0279] Through Figure 7 the example, it can be seen that when the user places an order through a taxi-hailing application on the first screen and enters the user interface provided by other applications, the user can trigger the electronic device to display order information on the second screen by flipping the electronic device back and forth, which is convenient for the user to view the order progress and improves the user experience.

[0280] Application scenario 5: The electronic device 100 receives a new message and displays the notification information of the new message on the first screen. The user can trigger the electronic device 100 to display the specific content of the new message on the second screen by flipping the electronic device 100 back and forth.

[0281] In application scenario 5, the electronic device 100 can run an application that can receive new messages in the background, such as a text message application, an instant messaging application, a ticket booking application (such as Booking, Qunar, Ctrip, etc.). The electronic device can receive a new message based on the application, and the new message may include, but is not limited to: text messages, instant messaging messages (such as WeChat messages, Skype messages), or application notification messages (such as push messages of the application), etc.

[0282] When the electronic device 100 receives a new message, it will display the notification information of the new message on the screen, and the notification information is usually a prompt window provided by the notification manager in the electronic device 100. Exemplarily, refer to Figure 8 8a of

[0283] As shown in 8a, the new message is a flight reminder message, which can be pushed by a ticketing application to the electronic device 100. The prompt window 501 is floatingly displayed above other content displayed on the electronic device 100. The prompt window 501 includes a general summary of the new message for prompting the user that a new message has been received. Generally, if the user wants to view the specific content of the new message, the user can click on the prompt window 501. In response to the user's operation of clicking on the prompt window 501, the electronic device 100 can display the specific content of the new message on the first screen. That is to say, generally, the user needs to view the specific content of the new message through a click operation. In the embodiments of the present application, the application for receiving the new message can be referred to as the first application, and the user interface 90 displayed by the electronic device on the first screen can be referred to as the first user interface.

[0284] In some embodiments, when the electronic device 100 is configured with a foldable display screen, Figure 8 in the example shown in 8a of

[0285] In some embodiments, when the electronic device 100 displays the notification information of a new message on the first screen, the second screen can be in a black screen state or can display content. The second screen being in a black screen state can mean that the electronic device 100 turns off the power supply of the second screen, or can mean that the second screen displays a black screen, which is not limited here.

[0286] In the embodiments of the present application, the user can flip the electronic device 100 back and forth to exchange the relative positions between the second screen and the first screen of the electronic device 100 and the user. For example, the user can flip the electronic device 100 in the direction of the arrow shown in Figure 8 . That is to say, after the user flips the electronic device 100 back and forth, the second screen faces the user and the first screen faces away from the user. In response to the user's operation of flipping the electronic device back and forth, the electronic device 100 can display the specific content of the new message on the second screen. Specifically, when the electronic device 100 displays the notification information of the new message on the first screen and detects the user's operation of flipping the electronic device back and forth, the electronic device 100 can call the application pushed to the new message, obtain the specific content of the new message, and display the specific content of the new message on the second screen. Here, for how the electronic device 100 detects the user's operation of flipping the electronic device back and forth, reference can be made to the relevant description in Application Scenario 1.

[0287] Exemplarily, referring to Figure 8 8b, which shows the specific content of the new message displayed on the second screen after the electronic device 100 detects the user's operation of flipping the electronic device back and forth. The specific content of the new message can include: airline, flight, departure location, destination, departure time, arrival time, etc. From 8a and 8b, it can be seen that the user can view the specific content of the new message on the second screen by operating the electronic device to flip it back and forth. In the embodiments of the present application, the user interface displayed on the second screen after the electronic device 100 is flipped back and forth (such as the user interface shown in 8b) can be called the second user interface.

[0288] In the embodiments of the present application, when the electronic device 100 displays the specific content of the new message on the second screen in response to the user's operation of flipping the electronic device back and forth, the first screen can not display any content, such as becoming a black screen state, or can continue to display the user interface 90, which is not limited here. In some embodiments, when the first screen continues to display the user interface 90, the notification information of the new message is no longer displayed in the user interface 90, that is, the notification information of the new message on the first screen is cleared. When the first screen continues to display the user interface 90, the electronic device 100 can receive the input user operation in the user interface 90 and make a response, or the user interface 90 is locked, that is, the electronic device 100 cannot receive the input user operation in the user interface 90 and make a response, which can prevent the user from accidentally triggering some functions of the electronic device 100 on the first screen.

[0289] In some embodiments, after the electronic device 100 displays the specific content of the new message on the second screen in response to the user's operation of flipping the electronic device back and forth, the user can also flip the electronic device 100 back and forth again, so that the electronic device 100 displays the user interface 90 on the first screen. Exemplarily, referring to Figure 8 FIG. 8a, when detecting the user's operation of flipping the electronic device 100 back and forth again, the electronic device 100 can display the user interface 90 on the first screen. When the electronic device displays the user interface 90 on the first screen, the second screen may not display any content, such as becoming a black screen state, or may continue to display the specific content of the new message, which is not limited here.

[0290] Through Figure 8 the example, when the electronic device displays the notification information of the new message on the first screen, the user can trigger the electronic device to display the specific content of the new message on the second screen by operating to flip the electronic device back and forth. The user can view the specific content of the new message through a simple user operation, and the user experience is good.

[0291] Not limited to the above-described 5 application scenarios, in the embodiments of the present application, the electronic device can also display corresponding content on the second screen in combination with other launched applications. For example, the electronic device can also run a navigation application. After the user selects a navigation route through the navigation application on the first screen and the electronic device displays the user interface provided by other applications, the user can trigger the electronic device to display the navigation interface provided by the navigation application on the second screen by operating to flip the electronic device back and forth. For another example, the electronic device can also run a text message application. When the electronic device receives a new text message and displays the notification information of the new text message on the first screen, the user can trigger the electronic device to display the specific content of the new text message on the second screen by operating to flip the electronic device back and forth. The specific content of the new text message may include the sender, the sending time, the text message content, etc.

[0292] (2) The user triggers the electronic device to display corresponding content on the second screen in combination with the current location by operating to flip the electronic device.

[0293] In the second case, the current location of the electronic device can be a subway station, a station, a shopping mall, a courier point, etc. The following describes the display method provided by the embodiments of the present application in combination with specific application scenarios.

[0294] Application scenario 6: When the user is at a subway station, view the content through the first screen of the electronic device 100. The user can trigger the electronic device 100 to display the subway ride code on the second screen by operating to flip the electronic device 100 back and forth.

[0295] Here, the subway ride code can be a two-dimensional code. The user can swipe the subway ride code on the card machine at the subway station to pay the fare and thus enter and exit the subway station.

[0296] In application scenario 6, when the user is at the subway station, the user can view the content through the first screen, and the content can be provided by any application. For example, the content on the first screen can be a reading interface, a video interface, an album, or a game interface, etc. Exemplarily, refer to Figure 9 9a of, which shows the user interface displayed on the first screen when the user is at the subway station. In the example shown in 9a, the first screen faces the user, and the second screen faces away from the user. In the embodiments of the present application, the user interface displayed by the electronic device on the first screen (such as the user interface shown in 9a) can be referred to as the first user interface.

[0297] In some embodiments, when the electronic device 100 is configured with a foldable display screen, Figure 9 in the example shown in 9a of, the foldable display screen is in a folded state. This folded state can be transformed from the unfolded state. When the foldable display screen is in the unfolded state, the foldable display screen can display a user interface, and the user interface is displayed on both the first screen and the second screen. Moreover, the content displayed on the user interface includes the content of the user interface displayed on the first screen when the foldable display screen is in the folded state (such as the content included in the user interface shown in 9a). In some embodiments, when the foldable display screen is in the folded state, the user interface can be displayed full screen. In some embodiments, the user interface displayed when the foldable display screen is in the unfolded state is an enlarged version of the user interface displayed on the first screen when the foldable display screen is in the folded state. In other embodiments, the user interface displayed when the foldable display screen is in the unfolded state not only includes the content in the user interface displayed on the first screen when the foldable display screen is in the folded state, but also can include other content, such as more text, controls, etc. In the embodiments of the present application, the user interface displayed when the foldable display screen is in the unfolded state can be referred to as the third user interface.

[0298] In some embodiments, when the electronic device 100 displays the interface as shown in 9a on the first screen, the second screen can be in a black screen state or can display content. The second screen being in a black screen state can mean that the electronic device 100 turns off the power supply of the second screen, or can mean that the second screen displays a black screen. There is no limitation here.

[0299] In the embodiments of the present application, the user can flip the electronic device 100 forward and backward to swap the relative positions between the second screen and the first screen of the electronic device 100 and the user. For example, the user can follow Figure 9Flip the electronic device 100 in the direction of the arrow shown. That is, after the user flips the electronic device 100 back and forth, the second screen faces the user and the first screen faces away from the user. When the user is at a subway station, in response to the operation of the user flipping the electronic device back and forth, the electronic device 100 can display a subway ride code on the second screen.

[0300] In a specific implementation, the electronic device 100 can obtain the current location information in the following ways: 1. Obtain the current location information through navigation systems such as GPS, GLONASS, and BDS. 2. Obtain the current location information through the network. For example, obtain the current location information through base station positioning, WiFi positioning, location based service (LBS), or geofencing technology, etc. After the electronic device 100 obtains the current location information, it can determine whether it is at a subway station.

[0301] Exemplarily, refer to Figure 9 Figure 9b, which shows the subway ride code displayed on the second screen of the electronic device 100 after detecting the operation of the user flipping the electronic device back and forth when the user is at a subway station. Here, the subway ride code displayed on the second screen can be obtained in the following way: The electronic device 100 calls the ride function provided by some applications, such as the ride mini-program of WeChat, to obtain the subway ride code. In the embodiments of the present application, the user interface displayed on the second screen after the electronic device 100 is flipped back and forth (such as the user interface shown in Figure 9b) can be referred to as the second user interface.

[0302] In some embodiments, to prevent misoperation, the electronic device 100 can also display the subway ride code on the second screen in combination with the time when the user is at a subway station. For example, if the time when the user is at a subway station is a predetermined time period (such as 7:00 - 9:00, 17:00 - 22:00 on weekdays, which respectively correspond to the user's working hours), then when the user flips the electronic device back and forth, the electronic device 100 displays the subway ride code on the second screen. Displaying the subway ride code on the second screen in combination with the time when the user is at a subway station can avoid the user accidentally triggering the display of the subway ride code on the second screen when the user is at a subway station but does not want to take the train, such as when the user passes by the subway station at 12:00 noon but does not want to take the train.

[0303] Not limited to the ride code shown in Figure 9b, in the embodiments of the present application, the electronic device can also provide the payment function for the user when taking a ride in other ways. For example, the electronic device can communicate with other devices through NFC. The user can add an NFC transit card to the wallet application in the electronic device 100 in advance. When the user is at the subway station, the user can flip the electronic device forward and backward to trigger the electronic device to start the wallet application, call the NFC transit card, and display the NFC transit card swiping interface on the second screen, so that the electronic device can complete the payment through the NFC transit card and take the ride smoothly.

[0304] In the embodiments of the present application, when the electronic device 100 displays the subway ride code or the NFC transit card swiping interface on the second screen in response to the user's operation of flipping the electronic device forward and backward, the first screen can not display any content, such as becoming a black screen state, or can continue to display the original user interface, which is not limited here. The first screen becoming a black screen state can mean that the electronic device 100 stops supplying power to the first screen, or can mean that the first screen displays a black screen, which is not limited here. In some embodiments, when the first screen continues to display the user interface as shown in Figure 9a, the electronic device 100 can receive the input user operation on this user interface and make a response. In other embodiments, when the first screen continues to display the user interface as shown in Figure 9a, this user interface is locked, that is, the electronic device 100 cannot receive the input user operation on this user interface and make a response, which can prevent the user from accidentally triggering some functions of the electronic device 100 on the first screen.

[0305] In some embodiments, after the electronic device 100 displays the subway ride code or the NFC transit card swiping interface on the second screen in response to the user's operation of flipping the electronic device forward and backward, the user can flip the electronic device 100 forward and backward again, so that the electronic device 100 displays the original content on the first screen. Exemplarily, referring to Figure 9 Figure 9a, when detecting the user's operation of flipping the electronic device 100 forward and backward again, the electronic device 100 can display the user interface as shown in Figure 9a on the first screen. When the electronic device displays the user interface as shown in Figure 9a on the first screen, the second screen can not display any content, such as becoming a black screen state, or can continue to display the subway ride code or the NFC transit card swiping interface, which is not limited here.

[0306] Through Figure 9 the above examples, when the user is at the subway station, by flipping the electronic device 100 forward and backward, the user can trigger the electronic device 100 to display the subway ride code or the NFC transit card swiping interface on the second screen. The user can complete the payment through this subway ride code or the NFC transit card swiping interface and take the ride smoothly. That is, the user can trigger the electronic device to display the subway ride code or the NFC transit card swiping interface through a simple user operation, which is convenient for the user to take the ride and provides a good user experience.

[0307] Application Scenario 7: When the user is in a shopping mall, the user views content through the first screen of the electronic device 100. The user can trigger the electronic device 100 to display a payment code on the second screen by operating the electronic device 100 to flip it forward and backward.

[0308] In Application Scenario 7, when the user is in a shopping mall, the user can view content through the first screen, and the content can be provided by any application. For example, the content on the first screen can be a reading interface, a video interface, an album, or a game interface, etc. Exemplarily, refer to Figure 10 Figure 10a, which shows the user interface displayed on the first screen when the user is in a shopping mall. In the example shown in Figure 10a, the first screen faces the user and the second screen faces away from the user. In the embodiments of the present application, the user interface displayed by the electronic device on the first screen (such as the user interface shown in Figure 10a) can be referred to as the first user interface.

[0309] In some embodiments, when the electronic device 100 is configured with a foldable display screen, Figure 10 in the example shown in Figure 10a, the foldable display screen is in a folded state. This folded state can be transformed from an unfolded state. When the foldable display screen is in the unfolded state, the foldable display screen can display a user interface, and the user interface is displayed on both the first screen and the second screen. Moreover, the content displayed on the user interface includes the content of the user interface displayed on the first screen when the foldable display screen is in the folded state (such as the content included in the user interface shown in Figure 10a). In some embodiments, when the foldable display screen is in the folded state, the user interface can be displayed full screen. In some embodiments, the user interface displayed when the foldable display screen is in the unfolded state is an enlarged user interface displayed on the first screen when the foldable display screen is in the folded state. In other embodiments, the user interface displayed when the foldable display screen is in the unfolded state not only includes the content of the user interface displayed on the first screen when the foldable display screen is in the folded state, but also can include other content, such as more text, controls, etc. In the embodiments of the present application, the user interface displayed when the foldable display screen is in the unfolded state can be referred to as the third user interface.

[0310] In some embodiments, when the electronic device 100 displays the user interface as shown in Figure 10a on the first screen, the second screen can be in a black screen state or can display content. The second screen being in a black screen state can mean that the electronic device 100 turns off the power supply of the second screen, or can mean that the second screen displays a black screen, and there is no limitation here.

[0311] In the embodiments of the present application, the user can flip the electronic device 100 forward and backward to swap the relative positions between the second screen and the first screen of the electronic device 100 and the user. For example, the user can follow Figure 10Flip the electronic device 100 in the direction of the arrow shown. That is, after the user flips the electronic device 100 back and forth, the second screen faces the user and the first screen faces away from the user. When the user is in a mall, in response to the user's operation of flipping the electronic device back and forth, the electronic device 100 can display a payment code on the second screen. Here, the manner in which the electronic device 100 obtains the current location information is the same as that in Application Scenario 6, and reference can be made to the relevant description. After the electronic device 100 obtains the current location information, it can determine whether it is in a mall.

[0312] Exemplarily, refer to Figure 10 Figure 10b, which shows the payment code displayed on the second screen of the electronic device 100 after the electronic device 100 detects the user's operation of flipping the electronic device back and forth when the user is in a mall. As shown in Figure 10b, the payment code can include a bar code and a QR code. Here, the payment code displayed on the second screen can be provided by a payment application (such as WeChat or Alipay) installed on the electronic device 100. In the embodiments of the present application, the user interface (such as the user interface shown in Figure 10b) displayed on the second screen after the electronic device 100 is flipped back and forth can be referred to as the second user interface.

[0313] Not limited to the payment code shown in Figure 10b, in the embodiments of the present application, the electronic device can also provide a payment function for the user in other ways when shopping. For example, the electronic device can communicate with other devices through NFC, and the user can add an NFC bank card to the wallet application in the electronic device 100 in advance. When the user is in a mall, the user can flip the electronic device back and forth to trigger the electronic device to start the wallet application, call the NFC bank card, and display an NFC bank card swiping interface on the second screen, which can enable the electronic device to complete the payment through the NFC bank card and complete the shopping smoothly.

[0314] In the embodiments of the present application, when the electronic device 100 displays a payment code or an NFC bank card swiping interface on the second screen in response to the user's operation of flipping the electronic device back and forth, the first screen can either not display any content, such as turning into a black screen state, or continue to display the original content, which is not limited here. The first screen turning into a black screen state can mean that the electronic device 100 stops supplying power to the first screen, or it can mean that the first screen displays a black screen, which is not limited here. In some embodiments, when the first screen continues to display the user interface as shown in Figure 10a, the electronic device 100 can receive the input user operation on this user interface and make a response. In other embodiments, when the first screen continues to display the user interface as shown in Figure 10a, this user interface is locked, that is, the electronic device 100 cannot receive the input user operation on this user interface and make a response, which can prevent the user from accidentally triggering some functions of the electronic device 100 on the first screen.

[0315] In some embodiments, after the electronic device 100 displays a payment code or an NFC bank card swiping interface on the second screen in response to the user's operation of flipping the electronic device back and forth, the user can also flip the electronic device 100 back and forth again, so that the electronic device 100 displays the original content on the first screen. Exemplarily, referring to Figure 10 as shown in 10a of Figure 10 , when detecting the user's operation of flipping the electronic device 100 back and forth again, the electronic device 100 can display the user interface as shown in 10a on the first screen, such as changing to a black screen state. When the electronic device displays the user interface as shown in 10a on the first screen, the second screen can either not display any content or continue to display the payment code or the NFC bank card swiping interface, which is not limited here.

[0316] Through Figure 10 the example, when the user is in a mall, the user can trigger the electronic device 100 to display a payment code or an NFC bank card swiping interface on the second screen by flipping the electronic device 100 back and forth. The user can complete the payment through the payment code or the NFC bank card swiping interface and smoothly shop. That is, the user can trigger the electronic device to display a payment code or an NFC bank card swiping interface through a simple user operation, smoothly shop, and have a good user experience.

[0317] In application scenario 7, when the user is in a mall, the user can trigger the electronic device to display a payment code or an NFC bank card swiping interface on the second screen by flipping the electronic device back and forth. In some other embodiments, when the user is in a mall, the user can also trigger the electronic device to display a discount code / coupon, an electronic movie ticket, a movie ticket collection code, etc. on the second screen by flipping the electronic device back and forth, which is convenient for the user to consume in the mall. Among them, the electronic movie ticket and the movie ticket collection code can be provided by a ticketing application (such as Maoyan, Taopiaopiao, Meituan, etc.).

[0318] Application scenario 8: When the user is near a smart locker, the user views the content through the first screen of the electronic device 100. The user can trigger the electronic device 100 to display a smart locker pick-up code on the second screen by flipping the electronic device 100 back and forth.

[0319] A smart locker refers to a self-service device installed in a public place for delivering and picking up express deliveries. The recipient can ask the express company to deliver the item to the designated smart locker, and then pick up the express by himself / herself with the pick-up code sent by the smart locker to the electronic device (such as a mobile phone). Here, the pick-up code can be a numerical password.

[0320] In application scenario 8, when the user is near a smart locker, the user can view the content through the first screen, and the content can be provided by any application. For example, the content on the first screen can be a reading interface, a video interface, an album or a game interface, etc. Exemplarily, referring to Figure 1111a shows a user interface displayed on the first screen when the user is near the parcel locker. In the example shown in 11a, the first screen faces the user and the second screen faces away from the user. In the embodiments of the present application, the user interface displayed by the electronic device on the first screen (such as the user interface shown in 11a) may be referred to as the first user interface.

[0321] In some embodiments, when the electronic device 100 is configured with a foldable display screen, Figure 11 in the example shown in 11a, the foldable display screen is in a folded state. This folded state can be transformed from the unfolded state. When the foldable display screen is in the unfolded state, the foldable display screen can display a user interface, and the user interface is displayed on both the first screen and the second screen. Moreover, the content displayed on the user interface includes the content of the user interface displayed on the first screen when the foldable display screen is in the folded state (such as the content included in the user interface shown in 11a). In some embodiments, when the foldable display screen is in the folded state, the user interface can be displayed full screen. In some embodiments, the user interface displayed when the foldable display screen is in the unfolded state is an enlarged version of the user interface displayed on the first screen when the foldable display screen is in the folded state. In other embodiments, the user interface displayed when the foldable display screen is in the unfolded state not only includes the content of the user interface displayed on the first screen when the foldable display screen is in the folded state, but may also include other content, such as more text, controls, etc. In the embodiments of the present application, the user interface displayed when the foldable display screen is in the unfolded state may be referred to as the third user interface.

[0322] In some embodiments, when the electronic device 100 displays the user interface as shown in 11a on the first screen, the second screen may be in a black screen state or may display content. The second screen being in a black screen state may mean that the electronic device 100 turns off the power supply of the second screen, or may mean that the second screen displays a black screen. There is no limitation here.

[0323] In the embodiments of the present application, the user can flip the electronic device 100 forward and backward to swap the relative positions between the second screen and the first screen of the electronic device 100 and the user. For example, the user can follow Figure 11Flip the electronic device 100 in the direction of the arrow shown. That is, after the user flips the electronic device 100 back and forth, the second screen faces the user and the first screen faces away from the user. When the user is near the express delivery locker, in response to the operation of the user flipping the electronic device back and forth, the electronic device 100 can display the express delivery pick-up code on the second screen. Here, the electronic device 100 can determine whether it is currently near the express delivery locker in the following ways: 1. The electronic device 100 obtains the current location information and determines whether it is currently near the express delivery locker according to the current location information. When the distance between the current location and the express delivery locker is less than a preset value (such as 10 meters, 20 meters, etc.), it can be determined that it is currently near the express delivery locker. Here, the way for the electronic device 100 to obtain the current location information is the same as that in Application Scenario 6, and reference can be made to the relevant description. 2. The express delivery locker can continuously broadcast messages using near-field communication methods such as WiFi, Bluetooth, NFC, etc. When the electronic device 100 receives the message sent by the express delivery locker, it can be determined that it is currently near the express delivery locker.

[0324] Exemplarily, refer to Figure 11 11b of, which shows the pick-up code displayed on the second screen after the electronic device 100 detects the operation of the user flipping the electronic device back and forth when the user is near the express delivery locker. In some embodiments, the second screen may also display one or more of the following: the express delivery company, the express delivery order number, the item picture, the item name, the address of the express delivery locker where the item is delivered, the company to which the express delivery locker belongs, etc. In the embodiments of the present application, the user interface displayed on the second screen after the electronic device 100 is flipped back and forth (such as the user interface shown in 11b) can be referred to as the second user interface.

[0325] Here, the pick-up code and other information displayed on the second screen can be obtained in the following ways: 1. Obtained by the electronic device from the database of the express delivery company. For example, the electronic device can send the express delivery order number to the server of the express delivery company, and the server searches for the information corresponding to the express delivery order number in the stored database and sends the information corresponding to the express delivery order number to the electronic device. Here, the information corresponding to the express delivery order number includes the pick-up code. 2. The electronic device reads the user's text message and obtains it from the user's text message. Specifically, after the express delivery company delivers the express to the express delivery locker, it can send a text message to the electronic device through the server, and the text message carries the pick-up code. 3. The electronic device obtains it from a third-party application (such as Taobao, JD.com, etc.). Specifically, the user usually purchases goods in a third-party application. After the goods are transported by the express delivery company, the third-party application will obtain the transportation situation feedback by the express delivery company, and the transportation situation includes the pick-up code.

[0326] In some embodiments, the user is near a parcel locker, but the user's parcel is not stored in this parcel locker, that is, the user's parcel is stored in another parcel locker. Therefore, to prevent accidental triggering of the display of the pick-up code on the second screen, the electronic device 100 may also display the pick-up code on the second screen in combination with the address of the parcel locker where the item is delivered. Specifically, when the electronic device 100 is near the parcel locker, it can compare the location of this parcel locker with the address of the parcel locker where the user's item is delivered to determine whether this parcel locker is the one where the item is delivered. If so, the electronic device 100 displays the pick-up code on the second screen. Among them, the address of the parcel locker where the user's item is delivered can be obtained by any one of the above three methods.

[0327] After the electronic device 100 displays the pick-up code on the second screen in response to the user's operation of flipping the electronic device back and forth, the user can extract the parcel with the pick-up code. For example, the user can input the pick-up code into the parcel locker, and the parcel locker opens the corresponding parcel compartment according to the received pick-up code, and the user can extract the parcel from the parcel compartment. In some embodiments, the second screen may also display a pick-up control 110. The user can click on the pick-up control 110. After the electronic device 100 detects the click operation input by the user, it can send the verification identifier (such as the pick-up code) of the parcel corresponding to the pick-up control to the parcel locker via Bluetooth, WiFi, NFC, cellular data network, etc., and the parcel locker can automatically open the corresponding parcel compartment according to the verification identifier for the user to extract the parcel.

[0328] In the embodiments of the present application, when the electronic device 100 displays the pick-up code on the second screen in response to the user's operation of flipping the electronic device back and forth, the first screen may not display any content, such as becoming a black screen state, or may continue to display the original content, which is not limited here. The first screen becoming a black screen state may mean that the electronic device 100 stops supplying power to the first screen, or may mean that the first screen displays a black screen, which is not limited here. In some embodiments, when the first screen continuously displays the user interface as shown in 11a, the electronic device 100 can receive and respond to the input user operations on this user interface. In other embodiments, when the first screen continuously displays the user interface as shown in 11a, this user interface is locked, that is, the electronic device 100 cannot receive and respond to the input user operations on this user interface, which can prevent the user from accidentally triggering some functions of the electronic device 100 on the first screen.

[0329] In some embodiments, after the electronic device 100 displays the pick-up code on the second screen in response to the user's operation of flipping the electronic device back and forth, the user can also flip the electronic device 100 back and forth again, so that the electronic device 100 displays the original user interface on the first screen. Exemplarily, see Figure 11When the operation of turning the electronic device 100 back and forth by the user is detected again at 11a, the electronic device 100 may display the user interface as shown in 11a on the first screen. When the electronic device displays the user interface as shown in 11a on the first screen, the second screen may not display any content, such as becoming a black screen state, or may continue to display the pickup code, which is not limited here.

[0330] Through Figure 11 As can be seen from the example, when the user is near the express delivery locker, the operation of turning the electronic device 100 back and forth can be used to trigger the electronic device 100 to display the pickup code on the second screen. The user can extract the express delivery through this pickup code. That is, the user can trigger the electronic device to display the pickup code through a simple user operation and smoothly extract the express delivery, providing a good user experience.

[0331] Combined with the above application scenarios 1-8, in some embodiments, in order to ensure the data security of the electronic device, the electronic device may prompt the user to verify their identity before displaying the corresponding content on the second screen. After the verification is passed, the electronic device displays the corresponding content on the second screen. Here, the user can verify their identity through one or more of the following: password, fingerprint, face, voiceprint, or gesture, etc. For example, in application scenario 7, after the electronic device detects the operation of the user turning the electronic device back and forth, it may prompt the user to verify their identity on the second screen. The user can input verification information to the electronic device. After the verification is passed, that is, when the input verification information is consistent with the pre-stored verification information, the electronic device will display the payment code on the second screen.

[0332] Combined with the above application scenarios 1-8, in some embodiments, when the user triggers the electronic device to display the corresponding content on the second screen through the operation of turning the electronic device back and forth, the area where the content is located may be related to the way the user holds the electronic device. Specifically, after the user turns the electronic device back and forth, the content on the second screen is displayed in the area not blocked by the user's hand, which is convenient for the user to view. Exemplarily, refer to Figure 12 of 12a, which shows the user interface displayed on the first screen when the electronic device 100 receives a new message. When the electronic device detects the operation of the user turning the electronic device back and forth, exemplarily, refer to Figure 12 of 12b. After the user turns the electronic device back and forth and holds the electronic device in a landscape orientation, the electronic device 100 may display the specific content of the new message in the left area on the second screen that is not blocked by the user's hand.

[0333] In a specific implementation, the electronic device 100 can detect the way the user holds the electronic device, so as to determine the area on the second screen that is not blocked by the user. Specifically, pressure sensors can be arranged under the second screen of the electronic device 100. When the user holds the electronic device, pressure acts on the pressure sensors at the corresponding positions. Therefore, the electronic device can calculate the touch point position of the user touching the second screen through the pressure measured by the pressure sensors, so as to determine the area of the second screen blocked by the user's hand. In some embodiments, pressure sensors can also be arranged at the frame position of the electronic device 100. The electronic device 100 can also calculate the touch point position of the user on the frame through the pressure measured by the pressure sensors, so as to assist in determining the area of the second screen blocked by the user's hand. For example, referring to Figure 12 12b, after the user flips the electronic device forward and backward and holds the electronic device in the manner shown in 12b, the electronic device 100 can detect the pressure when the user holds the electronic device through the pressure sensors arranged at the second screen and / or the frame position, and determine the touch point position shown in 12b. According to the touch point position shown in 12b, the electronic device can determine that the current user's hand blocks the right area of the second screen.

[0334] In the embodiments of the present application, in addition to displaying corresponding content on the second screen of the electronic device in combination with a specific scenario, in response to the operation of the user flipping the electronic device forward and backward, pre-set content can also be displayed on the second screen. The pre-set content can be set by the electronic device or the user, and there is no limitation here. For example, the electronic device or the user can set the content to a time and weather Widget, a calendar, a schedule, etc. Exemplarily, referring to Figure 13 13a, which shows the user interface displayed on the first screen. The user interface includes icons of applications installed on the electronic device, a status bar, and a navigation bar. In the example shown in 13a, the first screen faces the user and the second screen faces away from the user. Exemplarily, referring to Figure 13 13b, in response to the operation of the user flipping the electronic device forward and backward, the electronic device 100 displays the pre-set time and weather widget on the second screen.

[0335] It can be understood that in the embodiments of the present application, the above embodiments can be combined. For example, one or more of Application Scenarios 4-Application Scenario 8 can occur simultaneously. For example, assuming that Application Scenario 5 and Application Scenario 6 occur simultaneously, that is, when the user is at the subway station, a new message is received, and the electronic device or the user pre-sets the second screen to display a time and weather Widget. Exemplarily, referring to Figure 14 14a, which shows the user interface displayed on the first screen. In the example shown in 14a, the first screen faces the user and the second screen faces away from the user. Exemplarily, referring to Figure 14In FIG. 14b, the user can trigger the electronic device to simultaneously display the specific content of the new message, the subway ride code, and the pre-set time and weather widget on the second screen by operating the electronic device to flip it forward and backward.

[0336] In some embodiments of the present application, the electronic device can also display pre-set content on the display screen in combination with the current posture. The following will be described in combination with application scenarios.

[0337] Application Scenario 9: When the user raises the electronic device to a vertical posture, the electronic device displays pre-set content on the display screen facing away from the user. The pre-set content may include one or more of the following: the logo of the brand to which the electronic device belongs, a personalized pattern or signature set by the user, etc.

[0338] Specifically, the electronic device being in a vertical posture means that the angle between the Y-axis of the electronic device and the vertical direction is within a pre-set angle (for example, 30 degrees). The vertical direction refers to the direction of the earth's gravity or the opposite direction. The electronic device can detect whether the electronic device 100 is in a vertical posture through one or more of a gyroscope sensor, an acceleration sensor, and a gravity sensor. Exemplarily, referring to Figure 15 , which shows the content displayed on the display screen facing away from the user when the user makes a call / answers a call, that is, when the electronic device is in a vertical posture.
