Description

[Technical Field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to Chinese Patent Application No. 202110484217.4, entitled "Display Control Method, Electronic Device, and Computer Storage Medium," filed with the State Intellectual Property Administration of China on April 30, 2021, which is incorporated herein by reference in its entirety.

[0002] This application relates to the field of electronic technology, and in particular to display control methods, electronic devices, and computer storage media. [Background technology]

[0003] With the continuous development of flexible display screen technology, the types of display screens of electronic devices are also changing significantly. As a new type of display screen, a foldable screen is used in electronic devices such as mobile phones. When a user does not need to use the mobile phone, the foldable screen can be folded to reduce the volume of the mobile phone and make it easier for the user to carry. When a user needs to use the mobile phone screen to perform operations such as reading and entertainment, the foldable screen can be unfolded to increase the area of ​​the display interface and provide a more comfortable usage experience for the user.

[0004] In addition, dual-screen mobile phones with both inner and outer screens are gradually becoming the development direction of future mobile phones. However, there are already two types of dual-screen mobile phones on the market. One type of dual-screen mobile phone has a large outer screen and can display a large amount of content. However, there are problems of increased cost and structural thickness, making it less practical and usable. In addition, from the perspective of application rules, experience content is usually directly mapped from the inner screen to the outer screen, and the interaction mode is the interaction mode of the inner screen. Therefore, adaptation or adjustment cannot be performed based on the size of the outer screen. Another type of dual-screen mobile phone has a small outer screen, and the functions displayed by this type of dual-screen mobile phone are limited, such as message reminders, answering and hanging up calls, and taking photos with the camera. In this case, other functions of the inner screen (such as navigation) cannot be effectively mapped to the outer screen for display, resulting in a poor user experience. Summary of the Invention [Means for solving the problem]

[0005] In view of this, it is necessary to provide a display control method, an electronic device, and a computer storage medium for a better user experience.

[0006] According to a first aspect, an embodiment of this application provides a display control method applied to an electronic device. The electronic device includes an inner screen, an outer screen, a front camera, and a rear camera. The inner screen is a foldable screen. The inner screen and the front camera are located on one side of the electronic device. The outer screen and the rear camera are located on the other side of the electronic device. The method includes the steps of: displaying an icon of a phone application on the outer screen when the inner screen is in a folded state; displaying a first interface of the phone application on the outer screen when an operation performed on the icon of the phone application is detected; and displaying a second interface of the phone application on the inner screen when an operation to unfold the inner screen is detected, wherein a number of elements displayed in the second interface is greater than a number of elements displayed in the first interface. In this embodiment of this application, the electronic device can determine or control the display of the inner screen and / or the outer screen by obtaining the status of the electronic device (e.g., folded state or unfolded state) so that user operation is more convenient, usable, and practical, and the user experience is enhanced. For example, the electronic device may determine or control the display of a call screen on the inner screen and / or outer screen based on the state of the electronic device.

[0007] In a possible design, the elements include any one or a combination of call logs, contacts, and a dialer, and the call logs include any one or a combination of caller ID, caller region, caller name, and whether the call is a spam call. In this design, when the electronic device is unfolded, various states (e.g., call logs, contacts, or dialer) may be effectively displayed on the outer screen, making it clear that the user performs operations directly on the outer screen. Optionally, the dialer is used as an example. When the electronic device is in a folded state, after the user taps the phone icon, if the user does not perform another action (e.g., unfold the electronic device), the electronic device may be configured to directly display the dialer to help the user make a call directly on the outer screen. As another example, when there is a missed call and the user does not unfold the electronic device, the electronic device may be configured to display the missed call on the outer screen and directly call back the call by using the displayed dialer.

[0008] In a possible design, when a missed call is displayed on the phone application icon, a first interface displays the call log and a second interface displays the call log, contacts, and dialer.

[0009] In a possible design, the method further includes: When the second interface is displayed on the inner screen, the outer screen is in a screen-off state.

[0010] In a possible design, the method further includes, when a folding operation of the inner screen is detected, setting the outer screen to a screen-off state and / or a screen-locked state, or keeping the outer screen locked and displaying a default user interface. In this design, when the electronic device transitions or switches to a user interface on the inner screen, in other words, when the electronic device switches from a folded state to an unfolded state, if the user closes the electronic device again (in other words, the electronic device switches back to a folded state), it is clear that the outer screen of the electronic device may be set to a screen-off state and / or a screen-locked state, or the outer screen may be kept locked and display a default user interface. This is not limited here.

[0011] According to a second aspect, an embodiment of the present application provides another display control method applied to an electronic device. The electronic device includes an inner screen, an outer screen, a front camera, and a rear camera. The inner screen is a foldable screen. The inner screen and the front camera are located on one side of the electronic device. The outer screen and the rear camera are located on the other side of the electronic device. The method includes the steps of: detecting a first user operation when the inner screen is in an unfolded state, the first operation acting on an icon of navigation software on the inner screen; displaying a main interface of the navigation software on the inner screen in response to the first operation; displaying a first navigation interface of the navigation software on the inner screen when a second user operation is detected; and displaying a second navigation interface of the navigation software on the outer screen when an operation to fold the inner screen is detected, the number of elements displayed in the second navigation interface being smaller than the number of elements displayed in the first navigation interface. In this embodiment of the application, the electronic device can determine or control the display of the inner screen and / or the outer screen by obtaining the status of the electronic device (e.g., folded state or unfolded state) so that the user's operation is more convenient, usable, and practical, and the user experience is enhanced. For example, the electronic device may determine or control the display of a navigation interface on the inner screen and / or the outer screen based on the state of the electronic device.

[0012] In a possible design, the elements displayed on the first navigation interface include a map interface and important information, and the elements displayed on the second navigation interface include important information, the important information including one or a combination of distance and time to a destination, turn signals, and distance in meters to a speed monitoring point.

[0013] In a possible design, the method further includes, when an operation to unfold the inner screen is detected, enlarging an element displayed on the second navigation interface and displaying the enlarged element on the inner screen. In this design, when the outer screen is switched to the inner screen again, the navigation information displayed on the outer screen may be enlarged and displayed on the inner screen, which obviously improves the user experience.

[0014] According to a third aspect, an embodiment of this application provides another display control method applied to an electronic device. The electronic device includes an inner screen, an outer screen, a front camera, and a rear camera. The inner screen is a folding screen. The inner screen and the front camera are located on one side of the electronic device. The outer screen and the rear camera are located on the other side of the electronic device. The method includes the steps of: displaying an icon of a message application on the outer screen when the inner screen is in a folded state; displaying a first interface of the message application on the outer screen when an operation performed on the icon of the message application is detected; and displaying a second interface of the message application on the inner screen when an operation to unfold the inner screen is detected, wherein a number of elements displayed in the second interface is greater than a number of elements displayed in the first interface. In this embodiment of this application, the electronic device can determine or control the display of the inner screen and / or the outer screen by obtaining the status of the electronic device (e.g., folded state or unfolded state) so that user operation is more convenient, usable, and practical, and the user experience is enhanced. For example, the electronic device may determine or control the display of messages on the inner screen and / or outer screen based on the state of the electronic device.

[0015] In a possible design, the elements displayed in the first interface include a message reminder, prompt information, and a voice reply button, and the elements displayed in the second interface include a message reminder, prompt information, a voice reply button, a reply box, and an input method call window, and the prompt information is used to prompt the user to unfold the inner screen.

[0016] In a possible design, the elements displayed in the second interface further include a home screen or an application interface that was displayed before the inner screen was last folded, and a message drop-down menu or prompt information is set on the home screen or application interface. It is clear that the design can help the user pull down the menu or click the prompt information to view and / or process the message.

[0017] In a possible design, the method further comprises the step of indicating on the outer screen that a message has been delivered or read when the operation of folding the inner screen is detected. In this design, when the electronic device is closed again, the electronic device may be configured to display information such as "An SMS message has arrived" or "An SMS message has been read" on the outer screen, which obviously provides a better user experience.

[0018] According to a fourth aspect, an embodiment of this application provides yet another display control method applied to an electronic device. The electronic device includes an inner screen, an outer screen, a front camera, and a rear camera. The inner screen is a foldable screen. The inner screen and the front camera are located on one side of the electronic device. The outer screen and the rear camera are located on the other side of the electronic device. The method includes the steps of detecting a user's operation on an icon of an application that can be converted to run in the background on the inner screen when the inner screen is in an unfolded state, displaying and executing the application that can be converted to run in the background on the inner screen in response to the user's operation, and switching the application to run in the background and switching to the outer screen when an operation to fold the inner screen is detected. In this embodiment of this application, the electronic device can determine or control the display of the inner screen and / or the outer screen by obtaining the status of the electronic device (e.g., folded state or unfolded state) so that the user's operation is more convenient, more usable, more practical, and the user experience is improved. For example, the electronic device may determine or control the display and execution of applications that can be converted to run in the background on the inner screen and / or the outer screen based on the status of the electronic device. Optionally, applications that can be converted to run in the background include, but are not limited to, music, recording, running count, etc.

[0019] In a possible design, the step of switching to the outer screen includes controlling the outer screen to display a screen-off interface and / or a screen-lock interface, or keeping the outer screen locked and displaying a default user interface. It is apparent that in this design, when the outer screen is locked, the outer screen may further configure and display corresponding control buttons for controlling applications running in the background, for example, icons of a music pause key or a close key, based on the screen-lock interface.

[0020] According to a fifth aspect, an embodiment of this application provides an electronic device. The electronic device includes an inner screen, where the inner screen is a foldable screen, an outer screen, a front camera, and a rear camera.

A mobile phone is used as an example to describe how the electronic device implements specific technical solutions in the embodiments.

[0033] 1 is a schematic diagram of a hardware structure of an electronic device according to an embodiment of the present application. For example, the electronic device includes a processor 110, an internal memory 121, an external memory interface 122, a first camera 131, a second camera 132, a first display screen 141, a second display screen 142, a sensor module 150, an audio module 160, a speaker 161, a handset 162, a microphone 163, a headset jack 164, a subscriber identification module (SIM) card interface 171, a universal serial bus (USB) interface 172, a charging management module 180, a power management module 181, a battery 182, a mobile communication module 191, and a wireless communication module 192. In addition, in this embodiment of the present application, the electronic device may further include a motor, an indicator, a button, etc. It should be understood that the hardware structure depicted in FIG. 1 is merely an example. An electronic device in this embodiment of this application may have more or fewer components than the electronic device depicted in the figures, two or more components may be combined, or there may be different configurations of components. The various components depicted in the figures may be implemented in hardware, software, or a combination of hardware and software, including one or more signal processing and / or application specific integrated circuits.

[0034] The following describes in detail the components of the electronic device with reference to FIG.

[0035] The processor 110 may include one or more processing units. For example, the processor 110 may include an application processor (AP), a modem processor, a graphics processing unit (GPU), an image signal processor (ISP), a controller, a memory, a video codec, a digital signal processor (DSP), a baseband processor, and / or a neural-network processing unit (NPU). The different processing units may be separate components or may be integrated into one or more processors.

[0036] In some embodiments, a cache configured to store instructions and data may further be disposed within processor 110. For example, the cache within processor 110 may be a cache memory. The cache may be configured to store instructions and / or data that are currently being used, generated, or recycled by processor 110. If processor 110 needs to use the instructions or data again, processor 110 may retrieve the instructions or data directly from the cache. This helps reduce the time it takes processor 110 to retrieve the instructions or data, helping to improve system efficiency.

[0037] The internal memory 121 may be configured to store programs and / or data. In some embodiments, the internal memory 121 includes a program storage area and a data storage area. The program storage area may be configured to store an operating system (e.g., Android or iOS), a computer program required by at least one function (e.g., a face recognition function or an audio playback function), etc. The data storage area may be configured to store data (e.g., audio data or facial images) created and / or collected in the process of using the electronic device. For example, the processor 110 may call up programs and / or data stored in the internal memory 121 to cause the electronic device to execute corresponding methods to realize one or more functions. For example, the processor 110 calls up some programs and / or data in the internal memory to cause the electronic device to execute the unlocking method provided in the embodiments of this application, allowing the user to quickly and conveniently unlock the electronic device to enter guest mode. The internal memory 121 may be a high-speed random access memory, a non-volatile memory, etc. For example, the non-volatile memory may include at least one of one or more disk memory devices, flash memory devices, and / or universal flash storages (UFS).

[0038] The external memory interface 122 may be configured to connect to an external storage card (e.g., a micro SD card) to expand the storage capabilities of the electronic device. The external storage card communicates with the processor 110 through the external memory interface 122 to achieve data storage functions. For example, the electronic device may store files such as images, music, and videos on the external storage card through the external memory interface 122.

[0039] The first camera 131 and the second camera 132 may each be configured to capture or collect moving images, still images, etc. The first camera 131 is used as an example. Generally, the first camera 131 includes a lens and an image sensor. An object is projected onto the image sensor by using an optical image generated by the lens, and the optical image is then converted into an electrical signal for subsequent processing.

[0040] For example, the image sensor may be a charge-coupled device (CCD) or a complementary metal-oxide-semiconductor (CMOS) photoelectric transistor. The image sensor converts the optical signal into an electrical signal and then transmits the electrical signal to the ISP. The ISP converts the electrical signal into a digital image signal. For a specific implementation of the second camera 132, please refer to the specific implementation of the first camera 131, and the details will not be described again here. It should be noted that in this embodiment of the application, the first camera 131 may include one or more cameras, and the second camera 132 may also include one or more cameras. This is not limited.

[0041] The first display screen 141 may include a display panel configured to display a user interface. The display panel may be a liquid crystal display (LCD), an organic light-emitting diode (OLED), an active-matrix organic light-emitting diode (AMOLED), a flexible light-emitting diode (FLED), a mini-LED, a micro-LED, a micro-OLED, a quantum dot light-emitting diode (QLED), or the like. For example, the electronic device may realize the display function by using a GPU, the first display screen 141, or an application processor. It should be noted that the first display screen 141 may be a foldable screen or a non-foldable screen. This is not limited. It should be noted that for a specific implementation of the second display screen 142, please refer to the specific implementation of the first display screen 141, and the details will not be described again here.

[0042] For example, the electronic device is an electronic device with a foldable screen and includes a first display screen 141 and a second display screen 142. The first display screen 141 is a foldable screen, and the second display screen 142 is a non-foldable screen (i.e., a flat screen). As shown in FIGS. 2A to 2D , the first display screen 141 and the first camera 131 are disposed on a first side of the electronic device, and the second display screen 142 and the second camera 132 are disposed on a second side of the electronic device. The first side and the second side of the electronic device are different. For example, the first side may be the front side of the electronic device, and the second side may be the back side of the electronic device. The first display screen 141 may be referred to as an inner screen, a main screen, etc., and the first camera 131 may be referred to as a front camera. The second display screen 142 may be referred to as an outer screen, an auxiliary screen, etc., and the second camera 132 may be referred to as a rear camera.

[0043] For example, the value of the included angle of the first display screen 141 may fall within the range of [0°, 180°]. For example, when the value of the included angle of the first display screen 141 is 0°, the first display screen 141 is in a folded state or a closed state (collectively referred to as a folded state hereinafter). When the value of the included angle of the first display screen 141 is 180°, the first display screen 141 is in an unfolded state. For example, the first display screen 141 depicted in FIGS. 2A to 2C is in an unfolded state. The first display screen 141 depicted in FIG. 2D is in a folded state. For example, when the first display screen 141 is in an unfolded state as depicted in FIGS. 2A to 2C, a user may fold the first display screen 141 so that the first display screen 141 is in a folded state as depicted in FIG. 2D. When the first display screen 141 is in a folded state as shown in FIG. 2D, the user may unfold the first display screen 141 so that the first display screen 141 is in an unfolded state as shown in FIGS. 2A to 2C.

[0044] As another example, the electronic device includes a first display screen 141 and a second display screen 142. The first display screen 141 is a folding screen, and the second display screen 142 is a folding screen. In other words, in this embodiment of the application, the first display screen 141 may be a folding screen, and the second display screen 142 may be a folding screen, or the second display screen may be a non-folding screen. This is not limited thereto.

[0045] For example, as shown in FIGS. 2A to 2D , when first display screen 141 is folded, first display screen 141 may be divided into first display area 141b and second display area 141c by using folding area 141a as a boundary. The electronic device may display different content in first display area 141b and second display area 141c. For example, first display area 141b and second display area 141c may have equal areas, and folding area 141a may be arranged along a first direction (e.g., the horizontal direction shown in the figures). In this manner, first display screen 141 may be folded vertically (e.g., folded up and down) along folding area 141a. Of course, in this embodiment of the present application, the folding direction of first display screen 141 is not limited. See, for example, FIGS. 2E and 2F . The first display screen 141 may alternatively be folded horizontally (e.g., folded left and right) along the folding region 141a (the vertical direction shown in the figure). In the following embodiments, a mobile phone that can be folded vertically (e.g., FIGS. 2A to 2D) is used as an example for illustration.

[0046] 2A and 2B, the first camera 131 is disposed in the region of the upper left corner of the first display screen 141. It should be understood that parameters such as the quantity and position of the first cameras 131 are not limited in this embodiment of the application. For example, in another embodiment, the first camera 131 may be disposed in the upper right corner, in the center, or in another appropriate position of the first display screen 141. There may be one, two, or more first cameras 131. Similarly, in this embodiment of the application, another component may be further disposed in the first display screen 141. This is not limited thereto.

[0047] 2C and 2D, the second display screen 142 is generally strip-shaped. The second display screen 142 is disposed at a central position corresponding to the first display area 141b on the rear surface of the electronic device. The area of ​​the second display screen 142 is smaller than the area of ​​the first display area 141b or the area of ​​the second display area 141c. For example, the area of ​​the second display screen 142 may be equal to half the area of ​​the first display area 141b, or may be smaller than half the area of ​​the first display area 141b, or may be adjusted based on specific circumstances. As another example, in another embodiment of this application, the second display screen 142 may be further configured to be equal in size to the first display area 141b or the second display area 141c and may be disposed with the second display area 141b or the second display area 141c accordingly. As another example, when both of the two display screens (i.e., the first display screen 141 and the second display screen 142) are foldable screens, the sizes of the two display screens may be exactly equal, the two display screens may be positioned correspondingly, and the folding areas 141a of the two display screens may also be positioned correspondingly.

[0048] 2C and 2D, the second camera 132 is disposed on the second display screen 142. Similarly, the number and location of the second cameras 132 are not limited in this embodiment of the application. For example, in another embodiment, there are one, two, or more second cameras 132 (for example, four second cameras are shown in the figures). As another example, the second camera 132 is disposed outside the area of ​​the second display screen 142; in other words, the second display screen 142 is disposed independently of the second camera 132. Similarly, in this embodiment of the application, another component may be further disposed on the second display screen 142. This is not limited thereto.

[0049] It may be understood that in this embodiment of the present application, the positional relationship, connection relationship, etc. between the second display screen 142 and the rear surface of the electronic device are not limited. For example, the second display screen 142 may be integrated with or separated from the rear surface of the electronic device.

[0050] Sensor module 150 may include one or more sensors, such as touch sensor 150A, pressure sensor 150B, distance sensor 150C, and acceleration sensor 150D. In some other embodiments, sensor module 150 may further include a gyroscope, a fingerprint sensor, an ambient light sensor, an optical proximity sensor, a bone conduction sensor, a temperature sensor, an infrared dot-matrix emitter, a light-projecting element, a time-of-flight (TOF) distance sensor, etc. For example, one or more of the infrared dot-matrix emitter, the light-projecting element, or the TOF distance sensor may be integrated into first camera 131 and / or second camera 132 and configured to collect a facial image of the user.

[0051] Touch sensor 150A may also be referred to as a "touch panel." Touch sensor 150A may be disposed on first display screen 141 and / or second display screen 142. Disposing touch sensor 150A on first display screen 141 is used as an example. Touch sensor 150A and first display screen 141 form a first touch screen, which is also referred to as a "first touch screen." Touch sensor 150A is configured to detect a touch operation performed on or near the touch sensor. Touch sensor 150A may forward the detected touch operation to an application processor to determine the type of touch event. The electronic device may provide a visual output, etc., related to the touch operation on first display screen 141. In some other embodiments, touch sensor 150A may alternatively be disposed on the surface of the electronic device, and the location of touch sensor 150A may differ from the location of first display screen 141.

[0052] The pressure sensor 150B is configured to sense a pressure signal and can convert the pressure signal into an electrical signal. For example, the pressure sensor 150B may be disposed on the first display screen 141 and / or the second display screen 142. Touch operations performed at the same touch position but with different touch operation strengths may correspond to different operation commands.

[0053] The distance sensor 150C, which may also be referred to as a proximity sensor 150C, is configured to measure distance. For example, in a photography scenario, the electronic device may perform distance measurement by using the distance sensor 150C to achieve fast focusing.

[0054] The acceleration sensor 150D can detect acceleration of the electronic device in various directions (usually in three axes). When the electronic device is stationary, the acceleration sensor 150D can detect the magnitude and direction of gravity. The acceleration sensor 150D can be further configured to recognize the orientation of the electronic device, which can be used for applications such as switching between landscape and portrait orientations and as a pedometer. For example, when the first display screen 141 of the electronic device is folded, the electronic device can use the acceleration sensor 150D to determine the value of the included angle between the first display area 141b and the second display area 141c. Based on the value of the included angle, the electronic device can determine whether the electronic device is in an unfolded state (as shown in FIGS. 2A to 2C) or a folded state (as shown in FIG. 2D). It should be noted that in this embodiment of the present application, other methods can also be used to determine the folded or unfolded state of the electronic device. This is not limited thereto.

[0055] The electronic device may implement audio functions, such as audio playback, recording, and voice wake-up functions, by using an audio module 160, a speaker 161, a handset 162, a microphone 163, a headset jack 164, an application processor, etc.

[0056] Audio module 160 may be configured to convert digital audio information into analog audio signals for output, and may also be configured to convert analog audio input into digital audio signals. Audio module 160 may be further configured to encode and / or decode audio signals. For example, audio module 160 may be located within processor 110, or several functional modules of audio module 160 may be located within processor 110.

[0057] The speaker 161, also called a "loudspeaker," is configured to convert an audio electrical signal into a sound signal. For example, an electronic device may use the speaker 161 to listen to music, make a hands-free call, or emit a voice prompt light.

[0058] The receiver 162, also referred to as an "earphone," is configured to convert audio electrical signals into sound signals. For example, when the electronic device responds to a call or voice information, the receiver 162 may be placed near a person's ear to answer the phone.

[0059] The microphone 163, also referred to as a "mike" or "mic," is configured to collect sound (e.g., ambient sound, including sound produced by a person or sound produced by a device) and convert the sound into audio electrical data. When making a phone call or transmitting voice information, a user may produce sound by using their mouth near the microphone 163, and the microphone 163 collects the sound produced by the user. It should be noted that at least one microphone 163 may be disposed in the electronic device. For example, two microphones 163 are disposed in the electronic device. Also, in addition to realizing sound collection, a noise reduction function may be further realized. As another example, alternatively, three, four, or more microphones 163 may be disposed in the electronic device so that in addition to realizing sound collection and noise reduction, sound source identification, directional recording functions, etc. may be further realized.

[0060] The headset jack 164 is configured to connect to a wired headset and may be a USB interface 172, or a 3.5 mm open mobile terminal platform (OMTP) standard interface or a cellular telecommunications industry association of USA (CTIA) standard interface.

[0061] The SIM card interface 171 is configured to connect to a SIM card. The SIM card may be inserted into or removed from the SIM card interface 171 to connect to or disconnect from the electronic device. The electronic device may support one or N SIM card interfaces, where N is a positive integer greater than 1. The SIM card interface 171 may support a nano-SIM card, a micro-SIM card, a SIM card, etc. Multiple cards may be inserted into the same SIM card interface 171 at the same time. The multiple cards may be of the same type or different types. The SIM card interface 171 may alternatively be compatible with different types of SIM cards. The SIM card interface 171 may alternatively be compatible with an external storage card. The electronic device interacts with a network by using a SIM card to realize functions such as telephone calls and data communications. In some embodiments, the electronic device may further use an eSIM, i.e., an embedded SIM card. The eSIM card may be integrated into the electronic device and cannot be separated from the electronic device.

[0062] The USB interface 172 is an interface that complies with the USB standard specifications, and may specifically be a mini USB interface, a micro USB interface, a USB Type-C interface, or the like. For example, the USB interface 172 may be configured to connect to a charger to charge the electronic device, or to connect the electronic device to a headset and play audio by using the headset. When the USB interface 172 can be connected to a headset, it may be understood that the USB interface 172 is used as a headset interface. As another example, in addition to being used as a headset interface, the USB interface 172 may be further configured to connect to another electronic device, for example, an AR device or a computer.

[0063] The charge management module 180 is configured to receive a charging input from a charger. The charger may be a wireless charger or a wired charger. In some wired charging embodiments, the charge management module 180 may receive the charging input of the wired charger through the USB interface 172. In some wireless charging embodiments, the charge management module 180 may receive the wireless charging input through a wireless charging coil of the electronic device. When charging the battery 182, the charge management module 180 may further provide power to the electronic device by using the power management module 180.

[0064] Power management module 181 is configured to connect battery 182, charging management module 180, and processor 110. Power management module 181 receives inputs / one input from battery 182 and / or charging management module 180 and provides power to processor 110, internal memory 121, first camera 131, second camera 132, first display screen 141, second display screen 142, etc. Power management module 181 may be further configured to monitor parameters such as battery capacity, battery cycle count, and battery health status (leakage or impedance). In some other embodiments, power management module 181 may alternatively be located within processor 110. In some other embodiments, power management module 181 and charging management module 180 may alternatively be located within the same component.

[0065] The mobile communication module 191 may be applied to an electronic device to provide wireless communication solutions including 2G / 3G / 4G / 5G, for example, the mobile communication module 191 may include at least one filter, a switch, a power amplifier, and a low noise amplifier (LNA).

[0066] The wireless communication module 192 may be applied to an electronic device to provide wireless communication solutions including a wireless local area network (WLAN) (e.g., a wireless fidelity (Wi-Fi) network), Bluetooth (BT), a global navigation satellite system (GNSS), frequency modulation (FM), near field communication (NFC) technology, infrared (IR) technology, etc. The wireless communication module 192 may be one or more components integrating at least one communication processor module.

[0067] In some embodiments, antenna 1 of the electronic device is coupled to mobile communication module 191 and antenna 2 is coupled to wireless communication module 192, thereby enabling the electronic device to communicate with another device. Specifically, mobile communication module 191 may communicate with another device through antenna 1, and wireless communication module 192 may communicate with another device through antenna 2.

[0068] It should be understood that all the following embodiments can be realized in an electronic device having the above-mentioned hardware structure. See Figures 3A and 3B. The electronic device displays a graphical user interface (GUI) on a first display screen 141 and a second display screen 142. For ease of explanation, the GUI will be simply referred to as a user interface hereinafter.

[0069] 3A is a schematic diagram of a user interface displayed on the first display screen 141 of the electronic device. For example, as depicted in FIG. 3A, the user interface displayed on the first display screen 141 may include a status bar, a home screen, and a dock bar. The status bar may include the name of the operator (e.g., China Mobile), the time, signal strength, current remaining battery power, etc. It may be understood that in some other embodiments, the status bar may further include another icon, for example, a Bluetooth icon, a Wi-Fi icon, or an alarm icon. The home screen includes icons of multiple applications. The dock bar may include icons of commonly used applications, etc.

[0070] 3B is a schematic diagram of a user interface displayed on the second display screen 142 of the electronic device. For example, as depicted in FIG. 3B, the user interface displayed on the second display screen 142 may include a status bar and a home screen. For example, the status bar may include signal strength, current remaining battery power, etc. It may be understood that in some other embodiments, the status bar may further include another icon, for example, a Bluetooth icon, a Wi-Fi icon, or an alarm icon. The home screen includes icons of multiple applications, for example, a time, a calendar, a camera icon, a phone icon, a message icon, and an email icon.

[0071] An electronic device with a foldable screen (e.g., the electronic device illustrated in FIG. 2) is used as an example below to describe some exemplary user interface changes corresponding to the display control method for the electronic device in the embodiments of this application. For example, for ease of description, in the following embodiments, the first display screen 141 is referred to as the inner screen, the second display screen 142 is referred to as the outer screen, the first camera 131 is referred to as the front camera, and the second camera 132 is referred to as the back camera.

[0072] As shown in Figures 4A and 4B, 5A and 5B, and 6A and 6B, the following uses Examples 1 to 3 as examples to explain changes in the user interface displayed on the outer screen when the electronic device is in a folded state, or changes in the user interface displayed on the inner screen and the outer screen when the electronic device is in a folded state and then unfolded.

[0073] Example 1: See Figures 3B, 4A, and 4B. When the electronic device is in the folded state, the user interface displayed on the outer screen may be depicted in Figure 3B.

[0074] Of course, it can be understood that when the electronic device is in a folded state, the outer screen may alternatively be in a screen-off state, a screen-lock state, etc., and the user interface depicted in FIG. 3B is not displayed. It can be understood that when the outer screen is in a screen-off state, a user can turn on the outer screen by using a gesture operation, a trigger command, a voice command, etc. For example, a gesture operation can be an operation such as tapping, double-tapping, pressing, and sliding on the outer screen. As another example, a trigger command can be receiving an incoming phone call, an SMS message, etc. This is not limited thereto.

[0075] 4A is a schematic diagram of a user interface on the outer screen when the electronic device is in a folded state and a user performs an operation on one of the application icons (e.g., the camera icon) on the outer screen depicted in FIG. 3B (e.g., taps the camera icon). For example, when the electronic device is in a folded state, after the user taps the camera icon, if the user does not perform another action (e.g., unfolds the electronic device), the electronic device may be configured to turn on a camera on the outer screen (e.g., the second camera 132) so that the user takes a picture by using the rear camera (e.g., the second camera 132) and the outer screen.

[0076] Optionally, when the electronic device is in a folded state, after the user taps the camera icon, if the user does not perform another action (e.g., unfold the electronic device), the electronic device may be configured to turn on a camera on the outer screen to take a picture by using the camera on the outer screen (e.g., the second camera 132), and the electronic device may be configured to display prompt information on the outer screen. For example, the outer screen may indicate that the electronic device may be unfolded to perform a preview on the inner screen.

[0077] 4B is a schematic diagram of a user interface on the inner screen when a user performs the operation according to FIG. 4A and unfolds the electronic device within a preset time (e.g., 1 to 2 seconds) (in other words, the electronic device is in an unfolded state). For example, as shown in FIG. 4B, when a user taps the camera icon on the outer screen and then unfolds the electronic device within a preset time (e.g., 1 to 2 seconds), it indicates that the user may want to use the camera on the inner screen (e.g., the first camera 131). In this case, the electronic device may be configured to switch to the inner screen when the electronic device is unfolded within the preset time, switch the rear camera (e.g., the second camera 132) to the front camera (e.g., the first camera 131), display an application interface of the camera icon on the inner screen, and transition to, for example, a selfie interface. In other words, when the electronic device is in a folded state and then the user performs an operation on one of the application icons (e.g., a camera icon) on the outer screen (e.g., taps the camera icon) and unfolds the electronic device within a preset time, the electronic device switches to the inner screen and correspondingly displays the application interface of the application icon.

[0078] As another example, if a user taps the camera icon while the electronic device is in a folded state, and then the user unfolds the electronic device after a preset time (e.g., 2 to 5 seconds), it indicates that the photo on the outer screen may be too small for preview and the user may want a larger preview photo. In this case, the electronic device may be configured to switch to the inner screen when the electronic device is unfolded so that the user can conveniently preview the photo but still take the photo using the rear camera (e.g., second camera 132). In this case, the inner screen is used to help the user preview the captured photo.

[0079] In other words, when the electronic device transitions or switches to a user interface on the inner screen and displays a camera icon application interface on the inner screen, the inner screen of the electronic device may be used in combination with a camera on the inner screen (e.g., the first camera 131, i.e., the front camera) and / or a camera on the outer screen (e.g., the second camera 132, i.e., the rear camera) to take a picture. For example, as shown in FIG. 4B , when the electronic device transitions or switches to a user interface on the inner screen and displays a camera icon application interface on the inner screen, the inner screen of the electronic device may be used in combination with a camera on the inner screen (e.g., the first camera 131) to take a selfie, or may switch to the camera on the inner screen to take a selfie.

[0080] Of course, as described above, the electronic device determines whether to perform camera switching based on whether the electronic device is unfolded within a preset time. For example, when the electronic device is unfolded within a preset time, the electronic device switches to the front camera. As another example, when the electronic device is unfolded after the preset time, the camera switching is not performed, and the rear camera is still used. Of course, in another embodiment, it is not limited to determining whether to perform camera switching based on a preset time, and it can be understood that whether to perform camera switching can alternatively be determined by using another condition. This is not specifically limited here. For example, in one embodiment, the determination may be performed by using eyes. For example, when it is determined that the user's eyes are focused on the outer screen, the electronic device may be configured to enable the rear camera (e.g., the second camera 132). When it is detected that the user's eyes are not focused on the outer screen, the electronic device may be configured to switch to the front camera (e.g., the first camera 131).

[0081] Example 2: See Figures 3B, 5A, and 5B. When the electronic device is in a folded state, the user interface displayed on the outer screen may be shown in Figure 3B. Of course, it may be understood that when the electronic device is in a folded state, the outer screen may be in a screen-off state, a screen-lock state, etc., and the user interface shown in Figure 3B may not be displayed.

[0082] 5A is a schematic diagram of a user interface on the outer screen when the electronic device is in a folded state and a user performs an operation on one of the application icons (e.g., the phone icon) on the outer screen depicted in FIG. 3B (e.g., taps the phone icon). For example, when the electronic device is in a folded state, after the user taps the phone icon, if the user does not perform another action (e.g., unfolds the electronic device), the electronic device may be configured to display call logs, contacts, a dialer, etc., directly on the outer screen, or any combination thereof.

[0083] Optionally, a dialer is used as an example: when the electronic device is in a folded state, after the user taps the phone icon, if the user does not perform another action (e.g., unfold the electronic device), the electronic device may be configured to directly display the dialer to help the user make a call directly on the outer screen.

[0084] As another example, when there is a missed call and the user does not unfold the electronic device, the electronic device may be configured to display the missed call on the outer screen and call the call back directly by using the displayed dialer.

[0085] As another example, in another embodiment, when the electronic device is in a folded state and an incoming call is displayed on the outer screen, a call screen may be displayed on the outer screen. For example, an answer icon, a disconnect icon, and a status bar (e.g., displaying the caller ID, caller region, caller name, and whether the call is a spam call) may be displayed. In the first case, when the user operates the answer icon, in response to the user operation, the electronic device may directly answer the call in the folded state in combination with the earphone of the electronic device without unfolding the electronic device.

[0086] In the second case, if the earphones are not placed on the outer screen of the electronic device or the position of the earphones is not suitable for receiving sound, the electronic device may answer the phone call directly in the folded state by using the external speaker without unfolding the electronic device.

[0087] In a third case, when an incoming call is displayed on the outer screen and the electronic device cannot answer the call in a folded state, the electronic device may be configured to unfold so as to switch to a user interface on the inner screen and perform a corresponding operation (e.g., answer or hang up).

[0088] In a fourth case, when an incoming call is displayed on the outer screen but the call cannot be answered when the electronic device is folded, the electronic device may be configured to answer the call directly by unfolding the electronic device.

[0089] It can be understood that the behaviors of the above four cases can be predefined or set in the setting icon on the first display screen 141.

[0090] 5B is a schematic diagram of a user interface on the inner screen when a user performs the operation according to FIG. 5A and unfolds the electronic device (in other words, the electronic device is in an unfolded state). For example, as shown in FIG. 5B, when a user taps a phone icon on the outer screen and then unfolds the electronic device, the electronic device may be configured to switch to the inner screen and display an application interface of the phone icon on the inner screen to help the user perform operations such as making a call. In other words, when the electronic device is in a folded state and then a user performs an operation on one of the application icons (e.g., the phone icon) on the outer screen (e.g., taps the phone icon) and unfolds the electronic device, the electronic device switches to the inner screen and correspondingly displays the application interface of the application icon.

[0091] Example 3: See Figures 3B, 6A, and 6B. When the electronic device is in a folded state, the user interface displayed on the outer screen may be shown in Figure 3B. Of course, it may be understood that when the electronic device is in a folded state, the outer screen may be in a screen-off state, a screen-lock state, or the like, and the user interface shown in Figure 3B may not be displayed.

[0092] FIG. 6A is a schematic diagram of the user interface on the outer screen when the electronic device is in a folded state, the outer screen receives a message reminder (e.g., indicating that one or more new messages have been received), and the user taps on the message.

[0093] As another example, when the electronic device is in a folded state and the user taps on a message, the user may further view or perform other operations directly on the outer screen without unfolding the electronic device.

[0094] As another example, in another embodiment, when the outer screen of the electronic device receives a message, for content that cannot be directly manipulated on the outer screen (e.g., information needs to be replied to), when the user taps the message, the outer screen may prompt with information such as "Please unfold your phone for use."

[0095] 6B is a schematic diagram of a user interface on the inner screen when a user performs the operation according to FIG. 6A (i.e., taps a message on the outer screen) and unfolds the electronic device (i.e., the electronic device is in an unfolded state). As shown in FIG. 6B, when a user taps a message on the outer screen and then unfolds the electronic device, the electronic device may be configured to switch to the inner screen and display a corresponding message application interface on the inner screen. In this way, the user may view the message or perform other operations on the message (e.g., reply to the message).

[0096] As another example, when a user taps a message on the outer screen but directly unfolds the electronic device without the user performing an action, the electronic device may be configured to switch to the inner screen, which transitions to the home screen or the application interface (e.g., see FIG. 3A ) that was displayed before the foldable screen (i.e., first display screen 141) was last closed (i.e., folded).

[0097] It can be appreciated that when the inner screen of the electronic device transitions to a home screen or an application interface that was displayed before the foldable screen (i.e., first display screen 141) was last closed, the user interface on the inner screen may further be configured with or display a message drop-down menu, prompt information, etc. In this manner, it may be convenient for the user to drop down the menu or tap the prompt information to view and / or process messages.

[0098] In the above-described Examples 1 to 3, it can be understood that when the electronic device shifts or switches to the user interface on the inner screen, the outer screen of the electronic device may be in a screen-off state and / or a screen-lock state, or the outer screen may be locked and maintained, and a default user interface may be displayed. This is not limited thereto. The default user interface may include information such as time and date. Specifically, the user may set the information to be displayed in the default user interface, for example, a preset pattern to be displayed, based on requirements.

[0099] Optionally, in the above-described Examples 1 to 3, when the electronic device transitions or switches to a user interface on the inner screen, in other words, when the electronic device switches from a folded state to an unfolded state, if the user closes the electronic device again (in other words, when the electronic device switches to a folded state again), the outer screen of the electronic device may be set to a screen-off state and / or a screen-locked state, or the outer screen may remain locked and a default user interface may be displayed. This is not limited here. For example, the user taps a message on the outer screen. When the electronic device switches from a folded state to an unfolded state and then the user closes the electronic device, the electronic device may be set to display information such as "An SMS message has arrived" or "An SMS message has been read" on the outer screen.

[0100] As represented in Figures 7A to 7D(2), 8A to 8C, and 9A to 9C, the following uses Examples 4 to 6 as examples to illustrate the changes in the user interface on the inner screen and outer screen when the electronic device is in an unfolded state and then closed.

[0101] Example 4: 7A to 7D(2) are schematic diagrams of the user interface on the inner screen when the inner screen is in use and one of the application icons (e.g., a navigation software icon) in the user interface depicted in FIG. 3A is operated.

[0102] The inner screen of the electronic device being in use can be understood as follows: When the inner screen of the electronic device is in an unfolded state, a corresponding user interface, such as a home screen or an application user interface, is displayed on the inner screen; when the corresponding user interface is displayed on the inner screen, a user may perform a corresponding operation based on requirements, so that the electronic device executes a corresponding display on the inner screen according to the user's operation.

[0103] For example, when the inner screen of the electronic device is in an unfolded state and the screen is unlocked, and a home screen is displayed on the inner screen, the electronic device detects a user tapping an application icon (e.g., a video playback software icon) on the home screen and displays a user interface of the video playback software on the inner screen in response to the tapping of the video playback software icon. As another example, when the inner screen of the electronic device is in an unfolded state and the screen is unlocked, and a user interface of an application is displayed on the inner screen, the user may perform a corresponding operation on a virtual button (or virtual key) included in the user interface to realize the corresponding control. For example, when the user interface of the video playback software is displayed on the inner screen and the electronic device detects a user operation (e.g., clicking a virtual button for controlling full-screen display of a video) performed by the user on the user interface of the video playback software, the electronic device displays and plays the corresponding video in full screen on the inner screen in response to the operation so that the user can watch the corresponding video.

[0104] As another example, as shown in Figures 7A to 7D(2), when a navigation software icon (see Figure 7A, hereinafter referred to as the first operation) is operated (e.g., clicked) on the inner screen, the main interface of the navigation software (see Figure 7B) is first displayed on the inner screen. Then, the user interface of the navigation software icon (i.e., the main interface) is displayed, and when a user's route search operation (see Figure 7C, hereinafter referred to as the second operation) on the main interface is detected, the corresponding route search results are displayed on the inner screen in response to the route search operation. Specifically, a map interface is displayed (see Figure 7D(1)), thereby allowing the user to easily reach the corresponding destination.

[0105] Generally, the user interface displayed on the inner screen of the electronic device is the user interface of the electronic device running an application in the foreground. The electronic device may run one or more applications in the foreground. In some embodiments, the electronic device may run one or more applications in the background while running one or more applications in the foreground. For example, if the application running in the foreground of the electronic device is video playback software, the user interface of the video playback software is displayed on the inner screen. For example, when the user interface of the video playback software is displayed on the inner screen, the electronic device may also run another application in the background, such as payment software.

[0106] 7D(2) is a schematic diagram of a user interface on the outer screen when an application icon depicted in FIGS. 7A to 7D(1) is operated and then the electronic device is closed (i.e., the electronic device is in a folded state). For example, as depicted in FIG. 7D(2), when the size of the outer screen is small, only a portion of the content of the navigation software may be displayed on the outer screen. For example, the navigation software interface may be reduced in size by a certain percentage and then mapped to the outer screen for display.

[0107] As another example, when the size of the outer screen is small, only some important information of the navigation software interface (see FIG. 7D(2)), such as the distance and time to the destination, turn signals (e.g., turn left or right after a certain number of meters), and the distance in meters to the speed monitoring point, may be displayed on the outer screen.

[0108] As another example, when the size of the outer screen is large, the outer screen may be configured to continue displaying the navigation software interface, specifically, the user interface of the navigation software displayed on the inner screen is automatically mapped to the outer screen for display. Alternatively, as another example, when the size of the outer screen is large, the outer screen may display only important information of the navigation interface, which may be specifically adjusted based on actual requirements. This is not limited here.

[0109] Example 5: Figures 8A and 8B are schematic diagrams of a user interface on an inner screen when another application icon (e.g., a music icon) within the user interface shown in Figure 3A is operated. Figure 8C is a schematic diagram of a user interface on an outer screen when the application icon shown in Figures 8A and 8B is operated and then the electronic device is closed (i.e., the electronic device is in a folded state). For example, in this case, the outer screen may be set to display a screen-off interface and / or a screen lock interface by default, or the outer screen may be locked, a default user interface is displayed, and the corresponding application operates in the background without stopping.

[0110] As another example, as shown in Figure 8C, in another embodiment, when the outer screen is locked, the outer screen may further set and display corresponding control button icons, such as a music pause key or a close key, based on the screen lock interface to control an application operating in the background.

[0111] It can be understood that in another embodiment, the music icon shown in Figure 8A can alternatively be replaced by another application that can be converted to operate in the background, such as a recording or a running count. This is not limited here. For example, when the user enables the recording function and then closes the electronic device, the electronic device may be set to switch the recording to background execution and display controls such as pausing the recording on the outer screen.

[0112] As another example, when the user enables the running count function and then closes the electronic device, the electronic device may be set to display information such as running heart rate, running distance, count pause, and running end on the outer screen.

[0113] Example 6: 9A and 9B are schematic diagrams of the user interface on the inner screen when the alarm on the inner screen sounds. Fig. 9C is a schematic diagram of the user interface on the outer screen when the alarm of Fig. 9B sounds and then the electronic device is closed (in other words, the electronic device is in a folded state). For example, as shown in Fig. 9C, in this case, the electronic device may be set to switch to the outer screen, and the outer screen continues to display the user interface with the alarm sounding.

[0114] As another example, in another embodiment, the outer screen of the electronic device may be set to a screen-off state, in which case the outer screen may be further configured to pause the alarm.

[0115] As another example, in this case, the outer screen of the electronic device may be set to a locked screen and an off screen, or the outer screen may be set to a locked screen but with a default user interface displayed, which is not limited hereto.

[0116] It may be understood that in another embodiment, the alarm icon shown in FIG. 9A may alternatively be replaced with an icon for an incoming call or an in-call icon. This is not limited here. The in-call icon is used as an example. For example, in a first scenario, if the electronic device is closed when the user is not connected to a Bluetooth device and is in a call, the electronic device may be configured to disconnect the call. In a second scenario, if the electronic device is closed when the user connects to the device using Bluetooth and is in a call, the electronic device may be configured to continue the call. In other words, in the second scenario, even if the user closes the electronic device at this point, the call can continue without being disconnected. In a third scenario, if the electronic device is not connected to Bluetooth when the user is in a video call, the electronic device may be configured to disconnect the call when the electronic device is closed (in other words, the electronic device is in a folded state). In a fourth scenario, when a user is on a video call, if the electronic device is connected to Bluetooth, the electronic device may be configured to disconnect the video call when the electronic device is closed (in other words, the electronic device is in a folded state), but the call continues.

[0117] As another example, when an application icon (e.g., a settings icon) other than the application icons in Examples 4, 5, and 6 is operated on the inner screen, and then the electronic device is closed, the outer screen of the electronic device may be set to a screen-off state and / or a screen-lock state by default, or the outer screen may be kept locked and a default user interface may be displayed. This is not limited here.

[0118] As shown in Examples 4 to 6, it can be understood that when the inner screen of an electronic device is changed from an unfolded state to a folded state, the electronic device can further turn off the inner screen. It should be noted that when the inner screen is folded to a folded state, a user interface or the like cannot normally be displayed to a user on the inner screen. Therefore, to reduce the power consumption of the electronic device, the inner screen may be turned off. Turning off the inner screen can be understood as follows: the inner screen is off and locked, or the inner screen is off but unlocked. In addition, when the electronic device folds the inner screen to a folded state, the user cannot normally use the inner screen; in other words, the user cannot perform normal operations on the inner screen to control the electronic device.

[0119] In Examples 4 to 6, in the above-mentioned case (specifically, when the electronic device switches from the unfolded state to the folded state), it can be understood that if the user unfolds the electronic device again (in other words, when the electronic device switches to the unfolded state again), the electronic device can be configured to switch to the inner screen and transition to the home screen or the application interface that was displayed before the foldable screen (i.e., the first display screen 141) was last closed. Alternatively, the inner screen can be configured to restart or display an application that can be converted to run in the background. This is not specifically limited here. The navigation information in Example 4 is used as an example. When the electronic device switches from the unfolded state to the folded state, if the user unfolds the electronic device again (in other words, when the electronic device switches to the unfolded state again), the electronic device can be configured to switch to the inner screen, enlarge the navigation information displayed on the outer screen, and display the enlarged navigation information on the inner screen.

[0120] The music icon in Example 5 is used as an example. When the electronic device switches from the unfolded state to the folded state and then the user unfolds the electronic device (in other words, the electronic device switches back to the unfolded state), the electronic device may be configured to switch to the inner screen and transition to the home screen or the application interface that was displayed before the foldable screen (i.e., first display screen 141) was last closed. Alternatively, the inner screen may be configured to restart or display a music application, etc. This is not specifically limited herein.

[0121] As represented in Figures 10A to 10C, Figures 11A and 11B, and Figures 12A to 12C, the following uses Examples 7 to 9 as examples to explain the changes in the user interface on the inner screen and outer screen when the electronic device is in an unfolded state and not covered.

[0122] Example 7: Please refer to Figures 10A and 10B. Figures 10A and 10B are schematic diagrams of a user interface on the inner screen when a selfie is taken by using the camera on the inner screen. Figure 10C is a schematic diagram of a user interface on the outer screen when the electronic device is not covered (in other words, the electronic device is in an unfolded state) in the scenario shown in Figures 10A and 10B. In this scenario, the outer screen of the electronic device is in a screen-off state. Of course, in another embodiment, the outer screen of the electronic device may alternatively be set to a screen-locked state, or a screen-off state and a screen-locked state, by default, or the outer screen may be kept locked and a default user interface may be displayed, or a default graphic may be directly displayed (as shown in Figure 10C). This is not limited here.

[0123] Example 8: See Figures 11A and 11B. Figures 11A and 11B are schematic diagrams of a user interface on the inner screen when a camera is used to take a rear-view photo on the inner screen. Figure 11C is a schematic diagram of a user interface on the outer screen when the electronic device is not covered (in other words, the electronic device is in an unfolded state) in the scenario depicted in Figures 11A and 11B. As depicted in Figure 11C, in this scenario, a viewfinder interface may be displayed on the outer screen of the electronic device.

[0124] As another example, in another embodiment, when a viewfinder interface is displayed on the outer screen of an electronic device, a user may enable an auxiliary screen (i.e., the outer screen) in a camera application on the inner screen to perform a cooperative action.

[0125] As another example, in another embodiment, the outer screen of the electronic device is not limited to displaying a viewfinder interface, and may also directly turn off the screen or display a preset pattern, which is not limited herein.

[0126] Example 9: Please refer to Figures 12A and 12B. Figures 12A and 12B are schematic diagrams of a user interface when a message is operated on the inner screen. Figure 12C is a schematic diagram of a user interface on the outer screen when the electronic device is not covered (in other words, the electronic device is in an unfolded state) in the scenario shown in Figures 12A and 12B. As shown in Figure 12C, it can be understood that in this scenario, the outer screen of the electronic device can display a preset pattern (e.g., a smiley face image). Of course, in another embodiment, the outer screen of the electronic device is not limited to displaying a preset pattern, and may also directly turn off the screen, lock the screen, etc. This is not limited here.

[0127] It can be understood that in this embodiment of the present application, the preset pattern can be static or dynamic. For example, the preset pattern can be a smiley face image or a landscape image. As another example, the preset pattern can change correspondingly with the motion content of the inner screen.

[0128] It can be understood that in another embodiment, the message shown in Figure 12A can alternatively be replaced with an interface corresponding to an icon such as a phone, map, or music, etc. This is not limited here.

[0129] It can be understood that the following will further illustrate the changes in user interface corresponding to the display control method for electronic devices provided in the embodiments of this application by using three specific application scenarios.

[0130] Application scenario 1: 13 mainly describes the crossover from the outer screen to the inner screen of an electronic device. Crossover means that for electronic products such as mobile phones, when a user is working on a screen, the user moves to another device or screen to continue working.

[0131] For example, when the electronic device is in a folded state, the electronic device receives a message by using social media software (e.g., Huawei MeeTime). Then, the user taps the message on the outer screen to perform an operation such as viewing. In the operation process, when the user unfolds the electronic device, the electronic device switches to the inner screen and displays the user interface just operated on the outer screen on the inner screen. Then, the user closes the electronic device in the user interface (in other words, the electronic device is in a folded state). The electronic device moves or switches to the outer screen and displays the unlocking interface on the outer screen.

[0132] Application scenario 2: Figure 14 mainly describes the crossover from the inner screen to the outer screen of an electronic device. Crossover means that for electronic products such as mobile phones, when a user is working on a screen, the user moves to another device or screen to continue working.

[0133] For example, when the electronic device is in an unfolded state, navigation is performed by using navigation software on the inner screen of the electronic device, and music is played simultaneously by using music software. When the user closes the electronic device (in other words, the electronic device is in a folded state), the electronic device switches to the outer screen to display the navigation software interface, and music is played in the background. Then, when the electronic device receives an information, the information is presented on the outer screen in the form of a small icon prompt, and the navigation interface is not blocked. It can be understood that the electronic device may control the display of the navigation software in the manner described in Example 4, and the details will not be described again here.

[0134] Application scenario 3: FIG. 15 mainly illustrates the display of the inner and outer screens of the electronic device when the electronic device is not covered.

[0135] For example, first, the electronic device defines a dynamic graphic display: when a user answers or makes a call on the inner screen, the dynamic graphic is displayed on the outer screen.

[0136] As another example, when a user plays a game on the inner screen, dynamic graphics are displayed on the outer screen. In this application scenario, it can be understood that the electronic device can alternatively disable the dynamic graphics. In this case, when the user answers a phone call, makes a call, or plays a game, the outer screen is displayed as an off screen. This is not limited here.

[0137] As another example, when a user needs to launch payment software, the user can set the payment application to launch on the inner screen, and the payment two-dimensional code will be displayed directly on the outer screen. In this way, in this scenario, the user does not need to turn the mobile phone over to align it with the code scanning window, but only needs to align the payment two-dimensional code displayed on the outer screen with the code scanning window.

[0138] In another embodiment, when a payment needs to be completed by performing verification using a method such as a password, it can be understood that a facial scan on the inner screen can be directly invoked to perform the verification so as to complete the payment. This method effectively ensures that user information will not be disclosed. It can be understood that in this embodiment of the application, the payment can be performed by performing verification using a camera on the inner screen, a 3D structured optical module, or another facial recognition module, or the payment can be performed by directly pressing or touching an in-screen fingerprint on the inner screen. This is not limited here.

[0139] Based on Figures 1, 2A to 2F, 3A and 3B, 4A and 4B, 5A and 5B, 6A and 6B, and 7A to 7D(2), 8A to 8C, 9A to 9C, 10A to 10C, 11A to 11C, 12A to 12C, and 13 to 15, the following describes a display control method for an electronic device provided in this application.

[0140] 16 is a schematic flowchart of a display control method for an electronic device according to an embodiment of the present application. The electronic device may be the electronic device shown in FIG. 1. As shown in FIG. 16, the method includes the following steps:

[0141] S101: The electronic device determines whether the electronic device is in a folded state, and executes step S102 if the electronic device is in a folded state, or executes step S105 if the electronic device is not in a folded state.

[0142] The electronic device may determine the folded or unfolded state of the electronic device by using the acceleration sensor 150D in the embodiment depicted in Figure 1 or in another manner, the details of which will not be described again here.

[0143] S102: Determine whether the electronic device has received an operation to change the electronic device from a folded state to an unfolded state, and if the electronic device has received an operation to change the electronic device from a folded state to an unfolded state, execute step S103, or if the electronic device has not received an operation to change the electronic device from a folded state to an unfolded state, execute step S104.

[0144] S103: In response to the electronic device receiving an operation that changes the electronic device from the folded state to the unfolded state, the display on the inner screen is controlled.

[0145] It can be understood that when the electronic device undergoes an operation that changes the electronic device from a folded state to an unfolded state, the display on the inner screen can be controlled as shown in Example 1, Example 2, Example 3, or Application Scenario 1. The details will not be described again here.

[0146] It may be understood that when the electronic device transitions or switches to the user interface on the inner screen, the outer screen of the electronic device may be in a screen-off state and / or a screen-lock state, or the outer screen may be kept locked and a default user interface may be displayed. This is not limited here. The default user interface may include information such as time and date. Specifically, the user may set the information displayed in the default user interface based on requirements. For example, a preset pattern may be displayed.

[0147] S104: Control the display on the outer screen when the electronic device is not subjected to an operation that changes the electronic device from the folded state to the unfolded state.

[0148] It may be understood that when the electronic device is not subjected to an operation that changes the electronic device from the folded state to the unfolded state, the display on the outer screen may be controlled as shown in Example 1, Example 2, Example 3, or Application Scenario 1. The details will not be described again here.

[0149] S105: Determine whether the electronic device has received an operation to fold the inner screen from the unfolded state to the folded state, and if the electronic device has received an operation to fold the inner screen from the unfolded state to the folded state, execute step S106; if the electronic device has not received an operation to fold the inner screen from the unfolded state to the folded state, execute step S107.

[0150] S106: In response to the electronic device receiving an operation to fold the inner screen from the unfolded state to the folded state, the electronic device controls the display on the outer screen.

[0151] It can be understood that when the electronic device undergoes an operation that changes the electronic device from the unfolded state to the folded state, the display on the outer screen can be controlled as shown in Example 4, Example 5, Example 6, or Application Scenario 2. The details will not be described again here.

[0152] When the inner screen of the electronic device is folded from the unfolded state to the folded state, the electronic device may further turn off the inner screen. It should be noted that when the inner screen is folded to the folded state, a user interface or the like cannot normally be displayed to a user on the inner screen. Therefore, to reduce the power consumption of the electronic device, the inner screen may be turned off. Turning off the inner screen may be understood as follows: the inner screen is off and locked, or the inner screen is off but unlocked. In addition, when the electronic device folds the inner screen to the folded state, the user cannot normally use the inner screen; in other words, the user cannot perform normal operations on the inner screen to control the electronic device.

[0153] S107: When the inner screen of the electronic device is in use and is not undergoing an operation to fold the inner screen from the unfolded state to the folded state, the electronic device controls the display on the inner screen and the outer screen based on the application.

[0154] It may be understood that when the inner screen of the electronic device is in use and is not undergoing an operation of folding the electronic device from the unfolded state to the folded state, the display on the inner screen and the outer screen may be controlled as illustrated in Example 7, Example 8, Example 9, or Application Scenario 3. The details will not be described again here.

[0155] It can be understood that embodiments of the present application provide an electronic device and a display control method for the electronic device, in which the electronic device determines or controls the display on the inner screen and / or the outer screen by obtaining the status of the electronic device (e.g., folded state or unfolded state), so that the user's operation is more convenient, more usable, more practical, and the user experience is enhanced.

[0156] 17 is a schematic flowchart of a display control method for an electronic device according to an embodiment of the present application. The electronic device may be the electronic device shown in FIG. 1. As shown in FIG. 17, the method includes the following steps:

[0157] S171: When the inner screen is in the folded state, display the phone application icon on the outer screen.

[0158] S172: When an operation performed on the icon of the phone application is detected, display a first interface of the phone application on the outer screen.

[0159] It can be understood that when an operation performed on the icon of the phone application (e.g., tapping the phone application as shown in FIG. 5A) is detected, a first interface of the phone application can be displayed on the outer screen.

[0160] S173: When an operation to unfold the inner screen is detected, a second interface of the phone application is displayed on the inner screen.

[0161] It can be seen that when an operation to unfold the inner screen is detected, a second interface of the phone application can be displayed on the inner screen (see FIG. 5B).

[0162] In one embodiment, it can be understood that the number of elements displayed in the second interface is greater than the number of elements displayed in the first interface. The elements include any one or combination of call logs, contacts, and dialer. The call logs include any one or combination of the calling number, calling region, caller name, and whether the call is a spam call.

[0163] For example, when a missed call is displayed on the phone application icon, the first interface may display the call log, and when switched to the inner screen, the second interface displays the call log, contacts, and dialer.

[0164] Of course, it can be understood that when the first interface is displayed on the outer screen, the first interface can display call logs, contacts, a dialer, etc., or any combination thereof. For details, please refer to the description of Example 2, and the details will not be described again here.

[0165] It may be appreciated that when the second interface is displayed on the inner screen, the outer screen may be in a screen-off state to reduce power consumption of the electronic device.

[0166] It can be understood that when the electronic device transitions or switches to a user interface on the inner screen, in other words, when the electronic device switches from a folded state to an unfolded state, if the user closes the electronic device again (in other words, the electronic device switches back to a folded state), the outer screen of the electronic device may be set to a screen-off state and / or a screen-locked state, or the outer screen may be kept locked and a default user interface may be displayed. For details, see Example 2. The details will not be described again here.

[0167] 18 is a schematic flowchart of yet another display control method for an electronic device according to an embodiment of the present application. The electronic device may be the electronic device shown in FIG. 1. As shown in FIG. 18, the method includes the following steps:

[0168] S181: When the inner screen is in the unfolded state, a first operation of the user is detected, and the first operation acts on an icon of the navigation software on the inner screen.

[0169] As depicted in FIG. 7A, it can be seen that the first operation may be a user tapping on an icon of the navigation software.

[0170] S182: In response to the first operation, display the main interface of the navigation software on the inner screen.

[0171] As shown in FIG. 7A, it can be seen that when the navigation software icon is operated (e.g., clicked) on the inner screen (see FIG. 7A), the main interface of the navigation software can be displayed on the inner screen (see FIG. 7B).

[0172] S183: When a second operation of the user is detected, display a first navigation interface of the navigation software on the inner screen.

[0173] For example, when the user interface (i.e., the main interface) of the navigation software icon is displayed and a route search operation (see FIG. 7C) is detected by the user on the main interface, the corresponding route search result is displayed on the inner screen in response to the route search operation. Specifically, a map interface is displayed (see FIG. 7D(1)), thereby allowing the user to easily reach the corresponding destination.

[0174] S184: When an operation of folding the inner screen is detected, a second navigation interface of the navigation software is displayed on the outer screen.

[0175] For example, it can be seen that when the application icon shown in Figures 7A to 7D(1) is operated and then the electronic device is closed (in other words, the electronic device is in a folded state), a second navigation interface of the navigation software is displayed on the outer screen (as shown in Figure 7D(2)).

[0176] For example, as shown in FIG. 7D(2), when the size of the outer screen is small, only a portion of the navigation software content may be displayed on the outer screen, e.g., the navigation software interface may be scaled down by a certain percentage and then mapped onto the outer screen for display.

[0177] As another example, when the size of the outer screen is small, only some important information of the navigation software interface may be displayed on the outer screen (see FIG. 7D(2)). For example, the important information may be, but is not limited to, the distance and time to the destination, turn signals (e.g., turn left or right after a certain number of meters), and the distance in meters to the speed monitoring point.

[0178] As another example, when the size of the outer screen is large, the outer screen may be configured to continue displaying the navigation software interface, specifically, the user interface of the navigation software displayed on the inner screen is automatically mapped to the outer screen for display. Alternatively, as another example, when the size of the outer screen is large, the outer screen may display only important information of the navigation interface, which may be specifically adjusted based on actual requirements. This is not limited here.

[0179] As another example, when the outer screen is switched to, the number of elements displayed in the second navigation interface may be smaller than the number of elements displayed in the first navigation interface, for example, the elements displayed in the first navigation interface include a map interface and important information, and the elements displayed in the second navigation interface include important information.

[0180] It may be understood that when the electronic device switches from an unfolded state to a folded state (in other words, an operation to unfold the inner screen is detected), the electronic device may be configured to switch to the inner screen, enlarge the navigation information displayed on the outer screen, and display the enlarged navigation information on the inner screen, in other words, enlarge the elements displayed in the second navigation interface, and display the enlarged elements on the inner screen.

[0181] 19 is a schematic flowchart of yet another display control method for an electronic device according to an embodiment of the present application. The electronic device may be the electronic device shown in FIG. 1. As shown in FIG. 19, the method includes the following steps:

[0182] S191: When the inner screen is in the folded state, display the icon of the message application on the outer screen.

[0183] S192: When an operation performed on the icon of the message application is detected, a first interface of the message application is displayed on the outer screen.

[0184] For example, when the electronic device is in a folded state and the outer screen receives a message reminder (e.g., indicating that one or more new messages have been received), and the user taps the message, a first interface of the messages application is displayed on the outer screen (as depicted in FIG. 6A).

[0185] S193: When an operation to unfold the inner screen is detected, a second interface of the message application is displayed on the inner screen.

[0186] It can be seen that when a user performs the operation according to FIG. 6A (i.e., taps on a message on the outer screen) and unfolds the electronic device (i.e., detects the operation to unfold the inner screen), a second interface of the message application is displayed on the inner screen (as shown in FIG. 6B).

[0187] In one embodiment, it can be understood that the number of elements displayed in the second interface is greater than the number of elements displayed in the first interface. For example, the elements displayed in the first interface include a message reminder, prompt information, and a voice reply button. The elements displayed in the second interface include a message reminder, prompt information, a voice reply button, a reply box, and an input method call window. The prompt information is used to prompt the user to unfold the inner screen.

[0188] As another example, when a user taps a message on the outer screen but directly unfolds the electronic device without performing any operation, the electronic device may be configured to switch to the inner screen. Additionally, the inner screen transitions to the home screen or an application interface (see, for example, FIG. 3A ) that was displayed before the foldable screen was last closed (i.e., folded). Of course, when the inner screen of the electronic device transitions to the home screen or an application interface that was displayed before the foldable screen was last closed, the user interface of the inner screen may further be configured with or display a message drop-down menu, prompt information, etc. In this way, it may be convenient for the user to drop down a menu or tap prompt information to view and / or process a message.
