[0027] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0028] Currently, to meet user needs, an increasing number of electronic devices are designed with two screens, one on the front and one on the back, capable of displaying the content of the front screen synchronously on the rear screen. However, when the content of the front screen is synchronized to the rear screen, users cannot monitor the content displayed on the rear screen, potentially leading to the leakage of user privacy information and causing information security issues.

[0029] To address the aforementioned problems, the inventors, through extensive research, discovered and proposed the content display method, apparatus, electronic device, and storage medium provided in the embodiments of this application. By displaying a thumbnail of the other screen on one screen during synchronous display on two screens, it facilitates monitoring the display status of the other screen from one screen, thereby improving information display security and user experience. The specific content display method will be described in detail in subsequent embodiments.

[0030] The following will describe the application environment of the display method that can be used for the content provided in the embodiments of this application.

[0031] Please see Figure 1 The electronic device 100 may be, but is not limited to, a mobile phone, tablet computer, game console, smart wearable device, in-vehicle device, or other electronic device. This embodiment will be described using a mobile phone as an example.

[0032] The electronic device 100 includes a foldable housing assembly 110, a flexible display screen 120, and electronic components (not shown in the figure). The electronic components are disposed within the foldable housing assembly 110, and the flexible display screen 120 is laid on the foldable housing assembly 110. The foldable housing assembly 110 serves to support the flexible display screen 120 and protect the electronic components. The electronic components may include, but are not limited to, a central processing unit, memory, camera, receiver, fingerprint module, etc., and specific electronic components are not limited in this embodiment.

[0033] The foldable housing assembly 110 includes a first housing 111, a second housing 112, and a pivot mechanism 113. The first housing 111 and the second housing 112 are respectively connected to both sides of the pivot mechanism 113. The second housing 112 can be folded or unfolded relative to the first housing 111 via the pivot mechanism 113, causing the foldable housing assembly 110 to drive the flexible display screen 120 to fold or unfold. When the foldable housing assembly 110 and the flexible display screen 120 are stacked, the electronic device 100 is relatively small in size, making it easy to store and carry. When the foldable housing assembly 110 and the flexible display screen 120 are unfolded, the electronic device 100 is relatively large in size, making it easier to display information.

[0034] Please see Figure 2In this embodiment, the flexible display screen 120 includes a first display portion (first screen) 121 connected to a first housing 111, a second display portion (second screen) 122 connected to a second housing 112, and a bent display portion 123 connected to the first display portion 121 and the second display portion 122. The first display portion 121, the second display portion 122, and the bent display portion 123 can correspondingly form multiple display areas (e.g., two display areas, three display areas, four display areas, ..., N display areas). The first display portion 121 and the second display portion 122 are folded or unfolded relative to the first housing 111 and the second housing 112, respectively. The bent display portion 123 is bent or flattened along with the folding or unfolding of the first display portion 121 and the second display portion 122. In some embodiments, the first display unit 121, the second display unit 122, and the bent display unit 123 can be an integral structure, making the flexible display screen 120 a single piece of flexible display screen; or, in other embodiments, the bent display unit 123 is a flexible portion that can be bent, while the first display unit 121 and the second display unit 122 can be non-flexible portions, and the first display unit 121 and the second display unit 122 are folded or unfolded relative to each other through the bent display unit 123. In this embodiment, when the first housing 111 and the second housing 112 are stacked, the first display unit 121 and the second display unit 122 are opposite to each other, making the electronic device 100 present an outward-folding screen structure, so that the user can still observe the display content of the flexible display screen 120 when it is folded, improving the convenience of using the electronic device 100. In some other embodiments, when the first housing 111 and the second housing 112 are stacked, the first display portion 121 and the second display portion 122 are close to each other, so that the electronic device 100 presents an inward folding screen structure, so as to protect the flexible display screen 120 from scratches and damage.

[0035] It should be understood that the names of the first display unit 121, the second display unit 122, and the bent display unit 123 are provided for ease of description only and are not intended to limit the structure of the flexible display screen 120. In actual application scenarios, the first display unit 121, the second display unit 122, and the bent display unit 123 may not have clear boundaries, or the flexible display screen 120 may appear in other dividing structures. For example, the flexible display screen 120 includes a first display unit 121 and a second display unit 122 connected to the first display unit 121, and the first display unit 121 and the second display unit 122 can rotate relative to each other to fold or unfold.

[0036] Please see Figure 3 , Figure 3This diagram illustrates a flowchart of a content display method according to an embodiment of this application. The method is used to display a thumbnail of one screen while two screens are simultaneously displayed, facilitating monitoring of the display status of the other screen from one screen, thereby improving information display security and user experience. In specific embodiments, this content display method is applied to, for example... Figure 15 The display device 200 showing the content and the electronic device 100 equipped with the display device 200 showing the content. Figure 16 The following will use an electronic device as an example to illustrate the specific process of this embodiment. Of course, it is understood that the electronic device used in this embodiment may include smartphones, tablets, wearable electronic devices, etc., and is not limited thereto. The following will focus on... Figure 3 The process is described in detail below. In this embodiment, the electronic device includes a first screen and a second screen that are positioned opposite each other. The method for displaying the content may specifically include the following steps:

[0037] Step S110: Display the first content on the first screen.

[0038] The first screen can be a screen facing the user (front screen), and the second screen can be a screen facing away from the user (rear screen).

[0039] In this embodiment, first content can be displayed on the first screen. This first content may include content corresponding to the lock screen interface, content corresponding to the desktop, content corresponding to the application interface, etc., and may include text content, image content, video content, etc., without limitation.

[0040] In some implementations, the electronic device may display first content on a first screen after receiving an operation to display content. For example, the electronic device may display first content on a first screen after receiving a first target operation applied to the electronic device; it may display first content on a first screen after receiving a first target voice input to the electronic device; or it may display first content on a first screen when the environmental parameters of the electronic device meet a first preset environmental parameter, wherein the environmental parameter may include ambient temperature, ambient humidity, etc., and is not limited thereto.

[0041] Step S120: After receiving the synchronization display operation, display the first content on the first screen and the second screen, and display the first content displayed on the second screen as a thumbnail on the first screen.

[0042] In this embodiment, during the process of displaying the first content on the first screen, the electronic device can detect whether a synchronous display operation has been received. If it is determined that a synchronous display operation has been received, the first content can be displayed on both the first and second screens after receiving the synchronous display operation, and the first content displayed on the second screen can be displayed as a thumbnail on the first screen.

[0043] In some implementations, during the process of displaying the first content on the first screen, the electronic device may detect whether a synchronous display operation has been received in real time, or at a preset time interval, or at a preset time point, or according to other preset conditions, etc., without limitation.

[0044] In some implementations, after receiving a synchronized display operation, the electronic device can display a first prompt message on the first screen, wherein the first prompt message is used to indicate that synchronized display of the first content has been enabled. As one approach, the first prompt message may include text prompts, voice prompts, vibration prompts, etc., and is not limited thereto. When the first prompt message is a text prompt, it may include "Enable external screen synchronization". Alternatively, when the duration of displaying the first prompt message on the first screen reaches a duration threshold, the display of the first prompt message on the first screen can be stopped.

[0045] In some implementations, the electronic device may determine that it has received a synchronized display operation upon receiving a second target operation applied to the electronic device; it may determine that it has received a synchronized display operation upon receiving a second target voice input to the electronic device; or it may determine that it has received a synchronized display operation upon the environmental parameters of the electronic device meeting a second preset environmental parameter, etc., without limitation.

[0046] In some implementations, the first screen may display a second target control, which can be used to trigger a synchronous display operation. While the electronic device is displaying the first content and the second target control on the first screen, it can detect touch operations applied to the second target control. Upon detecting and receiving a third touch operation applied to the second target control, it can be determined that a synchronous display operation has been received. This third touch operation may include single-finger tap, two-finger tap, multi-finger tap, single-finger press, two-finger press, multi-finger press, single-finger long press, two-finger long press, multiple long presses, etc., and is not limited thereto.

[0047] As one possible approach, the second target control may include an application window, or a desktop top bar, etc., without limitation.

[0048] Please see Figure 4 , Figure 4 A schematic diagram of a first interface of a first screen provided in an embodiment of this application is shown. For example... Figure 4 As shown, the first screen 121 can display first content A and second target control B. The first screen 121 and the second screen 122 can be synchronously displayed by a third touch operation (such as long press) applied to the second target control B. At this time, the first screen 121 can display the prompt message "Enable simultaneous display of external screen".

[0049] In some implementations, after receiving a synchronization display operation, the electronic device can synchronize the first content displayed on the first screen to the second screen. Accordingly, both the first and second screens display the first content, and the first content displayed on the second screen is displayed as a thumbnail on the first screen. Based on this, if the content displayed on the first screen changes, the content displayed on the second screen changes accordingly while remaining consistent, and simultaneously, the content displayed as a thumbnail on the first screen changes accordingly while remaining consistent.

[0050] In some implementations, the initial display position of the thumbnail on the first screen can be at the edge of the first screen, so as to reduce obstruction of the content display on the first screen.

[0051] As one possible approach, if the first content displayed on the second screen is displayed as a thumbnail on the first screen, and a zoom operation is received on the thumbnail, the display size of the thumbnail on the first screen can be changed in response to the zoom operation.

[0052] As another feasible approach, when the first content displayed on the second screen is displayed as a thumbnail on the first screen, if a movement operation is received on the thumbnail, the display position of the thumbnail on the first screen can be changed in response to the movement operation.

[0053] Please see Figure 5 , Figure 5 This illustration shows a first comparative diagram of a first screen and a second screen provided in an embodiment of this application. For example... Figure 5 As shown, the first screen 121 and the second screen 122 can display the first content A, and the first screen 121 displays the first content A displayed on the second screen in the form of a thumbnail C.

[0054] One embodiment of this application provides a method for displaying content. First content is displayed on a first screen. Upon receiving a synchronized display operation, the first content is displayed on both the first and second screens. The first content displayed on the second screen is also displayed as a thumbnail on the first screen. This allows for simultaneous display on both screens, with a thumbnail of the other screen displayed on one screen, facilitating monitoring of the other screen's display status and improving information display security and user experience.

[0055] Please see Figure 6 , Figure 6 A flowchart illustrating a method for displaying content according to an embodiment of this application is shown. The method is applied to an electronic device including a first screen and a second screen disposed opposite to each other. The following will focus on... Figure 6 The process shown is described in detail, and the method of displaying the content may specifically include the following steps:

[0056] Step S210: Display the first content on the first screen.

[0057] Step S220: After receiving the synchronous display operation, display the first content on the first screen and the second screen, and display the first content displayed on the second screen as a thumbnail on the first screen.

[0058] For a detailed description of steps S210-S220, please refer to steps S110-S120, which will not be repeated here.

[0059] Step S230: After receiving the operation to pause synchronous display, the content most recently displayed on the first screen before receiving the operation to pause synchronous display is displayed on the second screen, and the content displayed on the second screen is displayed on the first screen in the form of a thumbnail.

[0060] In this embodiment, during the process of synchronously displaying the first content on the first screen and the second screen, the electronic device can detect whether it has received an operation to pause the synchronous display. Upon confirming that an operation to pause the synchronous display has been received, the second screen can display the content most recently displayed on the first screen before the operation was received, and the content displayed on the second screen can be displayed as a thumbnail on the first screen.

[0061] Upon receiving a pause synchronization operation, the electronic device can pause the synchronization of content displayed on the first screen to the second screen. At this time, the second screen retains the content most recently displayed on the first screen before the pause operation was received. Based on this, the first screen can update its display content, but the second screen will not update accordingly; that is, it will retain the content most recently displayed on the first screen before the pause operation was received. For example, the second screen can display a full-screen image from the photo album, a full-screen video playing in a video app (without interrupting video playback), or a slide from a presentation. In other words, switching applications or changing pages within an application on the first screen will not be projected onto the second screen.

[0062] In some implementations, upon receiving an operation to pause synchronized display, the content most recently displayed on the first screen before receiving the operation can be detected. Specifically, if it is determined that the most recently displayed content on the first screen before receiving the operation was "first content," and the content displayed on the first screen after receiving the operation is also "first content," then the first content can be displayed on both the first and second screens, and the first content displayed on the second screen can be displayed as a thumbnail on the first screen. Conversely, if it is determined that the most recently displayed content on the first screen before receiving the operation was "first content," and the content displayed on the first screen after receiving the operation is "second content," which is different from the first content, then the second content can be displayed on the first screen, the first content on the second screen can be displayed, and the first content displayed on the second screen can be displayed as a thumbnail on the first screen.

[0063] In some implementations, after receiving an operation to pause synchronous display, the electronic device can display a second prompt message on the first screen, wherein the second prompt message is used to indicate that the synchronous display of the second content has been paused. As one approach, the second prompt message may include text prompts, voice prompts, vibration prompts, etc., and is not limited thereto. When the second prompt message is a text prompt, it may include "Pause external screen synchronous display". Alternatively, if the duration for which the second prompt message is displayed on the first screen reaches a certain threshold, the display of the second prompt message on the first screen can be stopped.

[0064] In some implementations, the electronic device may determine that it has received a pause synchronous display operation upon receiving a third target operation applied to the electronic device; it may determine that it has received a pause synchronous display operation upon receiving a third target voice input to the electronic device; it may determine that it has received a pause synchronous display operation upon receiving environmental parameters that satisfy a third preset environmental parameter, etc., without limitation.

[0065] In some implementations, after receiving a synchronization display operation, the first screen can display a first target control in a first state. The first target control in the first state indicates that the content synchronization between the first and second screens has not been paused. During the process of synchronously displaying first content on the first and second screens, the electronic device can detect touch operations applied to the first target control in the first state. If a first touch operation is detected on the first target control in the first state, it can be determined that an operation to pause synchronization display has been received, and the first target control is switched from the first state to a second state. The first target control in the second state indicates that the content synchronization between the first and second screens is paused. The first touch operation can include single-finger tap, two-finger tap, multi-finger tap, single-finger press, two-finger press, multi-finger press, single-finger long press, two-finger long press, multiple long presses, etc., and is not limited here.

[0066] As one possible approach, the first target control can be displayed floatingly on the content displayed on the first screen, and the floating position of the first target control can be connected to or adjacent to the floating position of the thumbnail, without limitation. The first target control can be a pin-shaped button, which is in the first state by default.

[0067] Please see Figure 7 , Figure 7 A second corresponding schematic diagram of the first screen and the second screen provided in an embodiment of this application is shown. For example... Figure 7 As shown, when the first screen 121 and the second screen 122 are displayed synchronously, the first screen 121 and the second screen 122 can display the first content A. The first screen 121 displays the first content A displayed by the second screen 122 in the form of a thumbnail C. The first screen 121 displays the first target control D in the first state. The user can pause the synchronous display of the first screen 121 and the second screen 122 by performing a first touch operation (such as clicking) on ​​the first target control D in the first state.

[0068] Please see Figure 8 , Figure 8A third corresponding schematic diagram of the first screen and the second screen provided in the embodiments of this application is shown. For example... Figure 8 As shown, when the first screen 121 and the second screen 122 are paused in synchronous display, the first screen 121 can display the second content E, and the second screen 122 can display the first content A. The first screen 121 displays the first content A displayed by the second screen 122 in the form of a thumbnail C. The first screen 121 displays the first target control D in the second state. The user can restore the synchronous display of the first screen 121 and the second screen 122 by performing a second touch operation (such as clicking) on ​​the first target control D in the second state.

[0069] Step S240: After receiving the operation to restore synchronized display, the content displayed on the first screen is synchronously displayed on the second screen, and the content displayed on the second screen is displayed on the first screen in the form of thumbnails.

[0070] In this embodiment, the electronic device displays the most recently displayed content on the first screen before receiving the pause synchronization operation on the second screen. While the content of the second screen is displayed as a thumbnail on the first screen, the device can detect whether a resume synchronization operation has been received. Upon confirming that a resume synchronization operation has been received, the content of the first screen can be synchronously displayed on the second screen, and the content of the second screen can be displayed as a thumbnail on the first screen.

[0071] Upon receiving an operation to restore synchronized display, the electronic device can synchronize the content displayed on the first screen to the second screen for display. At this time, the second screen maintains synchronized display with the content of the first screen. Based on this, the first screen can update its displayed content, and the second screen updates accordingly. Simultaneously, the content displayed as a thumbnail on the first screen also updates accordingly.

[0072] In some implementations, upon receiving an operation to restore synchronized display, the content displayed on the first screen after receiving the operation can be detected. Specifically, if it is determined that the content displayed on the first screen after receiving the operation is second content, then the second content can be simultaneously displayed on the second screen, and the second content displayed on the first screen can be displayed as a thumbnail. If it is determined that the content displayed on the first screen after receiving the operation is a third content different from the first and second content, then the third content can be simultaneously displayed on the second screen, and the third content displayed on the first screen can be displayed as a thumbnail.

[0073] In some implementations, after receiving an operation to restore synchronized display, the electronic device can display a third prompt message on the first screen, wherein the third prompt message is used to indicate that the synchronized display of the second content has been restored. As one approach, the third prompt message may include text prompts, voice prompts, vibration prompts, etc., and is not limited thereto. When the third prompt message is a text prompt, it may include "Restore external screen synchronization". Alternatively, if the duration of displaying the third prompt message on the first screen reaches a duration threshold, the display of the third prompt message on the first screen can be stopped.

[0074] In some implementations, the electronic device may determine that it has received an operation to restore synchronized display upon receiving a fourth target operation applied to the electronic device; it may determine that it has received an operation to restore synchronized display upon receiving a fourth target voice input to the electronic device; or it may determine that it has received an operation to restore synchronized display upon the environmental parameters of the electronic device satisfying a fourth preset environmental parameter, etc., without limitation.

[0075] In some implementations, after receiving a synchronization display operation, the first screen can display a first target control in a first state, and can respond to a first touch operation applied to the first target control in the first state to display a first target control in a second state. The first target control in the second state indicates that the content synchronization of the first and second screens is paused. During the process of the electronic device displaying the most recently displayed content on the first screen before receiving the pause synchronization display operation on the second screen, it can detect touch operations applied to the first target control in the second state. If a second touch operation is detected applied to the first target control in the second state, it can determine that a resume synchronization display operation has been received, and switch the first target control from the second state to the first state. The first target control in the first state indicates that the content synchronization of the first and second screens has resumed. The second touch operation can include single-finger tap, two-finger tap, multi-finger tap, single-finger press, two-finger press, multi-finger press, single-finger long press, two-finger long press, multiple long presses, etc., and is not limited here.

[0076] Please see Figure 9 , Figure 9 This illustration shows a fourth corresponding diagram of the first screen and the second screen provided in an embodiment of this application. For example... Figure 9As shown, when the first screen 121 and the second screen 122 resume synchronized display, the first screen 121 can display the second content E, the second screen 122 can display the second content E, the first screen 121 displays the second content E displayed by the second screen 122 in the form of a thumbnail C, and the first screen 121 displays the first target control D in the first state.

[0077] Please see Figure 10 , Figure 10 This application shows Figure 6 The flowchart below illustrates the steps S240 of the method for displaying the shown content. Figure 10 The process shown will be described in detail, and the method may specifically include the following steps:

[0078] Step S241: After receiving the operation to restore synchronized display, output a prompt message.

[0079] In this embodiment, after determining that the operation to restore synchronized display has been received, a prompt message can be output in response to the operation. The prompt message is used to prompt the user to confirm / select whether to restore the synchronization of the content of the first screen to the second screen for display.

[0080] In some implementations, the prompt message may include one or a combination of text prompt messages, voice prompt messages, and vibration prompt messages.

[0081] As an option, the prompt can be a pop-up message, which allows subsequent steps to proceed only after the user has interacted with the pop-up message.

[0082] Step S242: In response to the confirmation information input based on the prompt information, the content displayed on the first screen is simultaneously displayed on the second screen, and the content displayed on the second screen is displayed on the first screen in the form of a thumbnail.

[0083] In this embodiment, during the output of the prompt information, the operation input based on the prompt information can be detected. The operation input based on the prompt information may include a confirmation operation or a rejection operation. The confirmation operation is used to indicate agreement to restore the content displayed on the first screen to the second screen in a synchronized manner, and the rejection operation is used to indicate refusal to restore the content displayed on the first screen to the second screen in a synchronized manner.

[0084] In one approach, upon receiving a confirmation operation based on the prompt information, it can be assumed that the user agrees to restore the content displayed on the first screen to the second screen in a synchronized manner. In response to the confirmation operation based on the prompt information, the content displayed on the first screen can be synchronized to the second screen. At this time, the content displayed on the first screen is displayed synchronously on the second screen, and the content displayed on the second screen is displayed on the first screen in the form of a thumbnail.

[0085] As another approach, when a rejection operation based on the prompt information is received, it can be assumed that the user refuses to restore the content displayed on the first screen to the second screen in synchronization. In this case, the user can respond to the rejection operation based on the prompt information by not synchronizing the content displayed on the first screen to the second screen. At this time, the second screen displays the content most recently displayed on the first screen before the operation to pause synchronization was received.

[0086] In some implementations, the prompt information may include pop-up prompts for two controls: "Yes" and "No". When a touch operation is detected on the "Yes" control, it can be confirmed that the input has been received as confirmation; when a touch operation is detected on the "No" control, it can be confirmed that the input has been received as rejection.

[0087] Please see Figure 11 , Figure 11 A schematic diagram of a second interface of the first screen provided in an embodiment of this application is shown. For example... Figure 11 As shown, the first screen 121 can display first content A and prompt information F. The prompt information F can include two controls: "Yes" and "No". The user can select whether to restore synchronized display based on the prompt information F.

[0088] An embodiment of this application provides a method for displaying content, in which first content is displayed on a first screen; upon receiving a synchronized display operation, the first content is displayed on both the first and second screens, and the first content displayed on the second screen is displayed as a thumbnail on the first screen; upon receiving a pause synchronized display operation, the content most recently displayed on the first screen before the pause operation is received is displayed on the second screen, and the content displayed on the second screen is displayed as a thumbnail on the first screen; upon receiving a resume synchronized display operation, the content displayed on the first screen is simultaneously displayed on the second screen, and the content displayed on the second screen is displayed as a thumbnail on the first screen. Compared to... Figure 3 The method for displaying the content shown in this embodiment can also pause or resume synchronization of the content displayed on the second screen, thereby protecting user information security and improving user experience.

[0089] Please see Figure 12 , Figure 12 A flowchart illustrating a method for displaying content according to an embodiment of this application is shown. The method is applied to an electronic device including a first screen and a second screen disposed opposite to each other. The following will focus on... Figure 12 The process shown is described in detail, and the method for displaying the content may specifically include the following steps:

[0090] Step S310: Display the first content on the first screen.

[0091] Step S320: After receiving the synchronization display operation, display the first content on the first screen and the second screen, and display the first content displayed on the second screen as a thumbnail on the first screen.

[0092] For a detailed description of steps S310-S320, please refer to steps S110-S130, which will not be repeated here.

[0093] Step S330: Receive the operation to end synchronized display.

[0094] In this embodiment, during the process of synchronously displaying the first content on the first screen and the second screen, the electronic device can detect whether it has received an operation to end the synchronous display. If it is determined that an operation to end the synchronous display has been received, the device can respond to the operation by stopping the synchronization of the content displayed on the first screen to the second screen.

[0095] In some implementations, if a synchronized display operation is received, it can be determined whether the second screen displays initial content before displaying the first content. The initial content may include content corresponding to the lock screen, the desktop, or the application interface, etc., and is not limited thereto. As one possible approach, it can be determined whether the second screen is on before displaying the first content. If it is determined that the second screen is on before displaying the first content, it can be determined that the second screen displays initial content before displaying the first content; if it is determined that the second screen is off before displaying the first content, it can be determined that the second screen does not display initial content before displaying the first content.

[0096] In some implementations, during the process of the electronic device synchronously displaying the first content on the first screen and the second screen, it can detect whether an operation to end synchronous display has been received in real time, or at a preset time interval, or at a preset time point, or according to other preset conditions, etc., without limitation.

[0097] In some embodiments, after receiving an operation to end synchronized display, the electronic device displays a fourth prompt message on the first screen, wherein the fourth prompt message indicates that the synchronized display of the first content has ended. As one approach, the fourth prompt message may include text prompts, voice prompts, vibration prompts, etc., and is not limited thereto. When the fourth prompt message is a text prompt, it may include "End external screen synchronization". Alternatively, if the duration of displaying the fourth prompt message on the first screen reaches a certain threshold, the display of the fourth prompt message on the first screen can be stopped.

[0098] In some implementations, the electronic device may determine that it has received an operation to end synchronous display upon receiving a fifth target operation applied to the electronic device; it may determine that it has received an operation to end synchronous display upon receiving a fifth target voice input to the electronic device; or it may determine that it has received an operation to end synchronous display upon the environmental parameters of the electronic device satisfying a fifth preset environmental parameter, etc., without limitation.

[0099] In some implementations, the first screen may display a second target control, which can be used to trigger an operation to end the synchronized display. During the process of the electronic device displaying first content and the second target control on the first screen and displaying the first content on the second screen, touch operations applied to the second target control can be detected. Upon detecting and receiving a fourth touch operation applied to the second target control, it can be determined that an operation to end the synchronized display has been received. This fourth touch operation may include a single-finger tap, a two-finger tap, a multi-finger tap, a single-finger press, a two-finger press, a multi-finger press, a single-finger long press, a two-finger long press, multiple long presses, etc., and is not limited thereto.

[0100] Step S340: If the second screen displays initial content before displaying the first content, then control the second screen to switch from displaying the first content to displaying the initial content.

[0101] In this embodiment, if it is determined that the second screen displays initial content before displaying the first content, the second screen can be controlled to switch from displaying the first content to displaying the initial content, so as to reduce the impact on the displayed content of the second screen.

[0102] Step S350: If the second screen has not displayed any initial content before displaying the first content, then control the second screen to turn off.

[0103] In this embodiment, if it is determined that the second screen has not displayed any initial content before displaying the first content, the second screen is turned off to reduce the power consumption of the electronic device.

[0104] An embodiment of this application provides a method for displaying content. First content is displayed on a first screen. Upon receiving a synchronized display operation, the first content is displayed on both the first and second screens. The first content displayed on the second screen is also displayed as a thumbnail on the first screen. Upon receiving an operation to end synchronized display, if the second screen displayed initial content before displaying the first content, the second screen is controlled to switch from displaying the first content to displaying the initial content. If the second screen did not display initial content before displaying the first content, the second screen is controlled to turn off. Compared to... Figure 3 In addition to the method of displaying the content shown, this embodiment can also restore the initial state of the second screen when the content synchronization of the second screen ends, so as to improve the user experience.

[0105] Please see Figure 13 , Figure 13 A flowchart illustrating a method for displaying content according to an embodiment of this application is shown. The method is applied to an electronic device including a first screen and a second screen disposed opposite to each other. The following will focus on... Figure 13 The process shown is described in detail, and the method for displaying the content may specifically include the following steps:

[0106] Step S410: Display the first content on the first screen.

[0107] For a detailed description of step S410, please refer to step S110, which will not be repeated here.

[0108] Step S420: After receiving the synchronous display operation, the first content is split into multiple sub-contents, and the multiple sub-contents are displayed on the first screen.

[0109] In this embodiment, the user may wish to synchronize all of the first content displayed on the first screen to the second screen for display, so as to achieve complete synchronization between the first and second screens. The first content displayed on the first screen may consist of a portion of non-private content and a portion of private content. In this case, for information security, the user may only wish to synchronize a portion of the non-private content to the second screen for display, while excluding the portion of the private content.

[0110] Based on this, after receiving the synchronous display operation, the electronic device can respond to the synchronous display operation by splitting the first content into multiple sub-contents and displaying the multiple sub-contents on the first screen.

[0111] As one feasible approach, upon receiving a synchronization display operation, the electronic device can respond by dividing the first content into multiple sub-contents according to different display areas. For example, assuming the display area of ​​the first electronic device is divided into a first display area and a second display area, the content displayed in the first display area can be divided into one sub-content, and the content displayed in the second display area can be divided into another sub-content.

[0112] As another feasible approach, upon receiving a synchronization display operation, the electronic device can respond by dividing the first content into multiple sub-contents according to the different applications corresponding to each content item. For example, assuming that each content item in the first content corresponds to a first application and a second application respectively, the content corresponding to the first application can be divided into one sub-content, and the content corresponding to the second application can be divided into another sub-content.

[0113] As another feasible approach, upon receiving a synchronization display operation, the electronic device can respond by splitting the first content into multiple sub-contents according to the different types of the content within it. For example, assuming that the content of the first content corresponds to a first type and a second type respectively, the content corresponding to the first type can be split into one sub-content, and the content corresponding to the second type can be split into another sub-content, such as the first type being an image and the second type being text.

[0114] As another feasible approach, upon receiving a synchronized display operation, the electronic device can respond by splitting the first content into multiple sub-contents based on the different keywords of each content item. For example, assuming that a certain content item in the first content corresponds to a target keyword, that content item can be split into one sub-content item from the first content, and the remaining content item in the first content can be split into another sub-content item. Target keywords could include passwords, ID card numbers, etc., without limitation.

[0115] As another feasible approach, upon receiving a synchronization display operation, the electronic device can respond by dividing the first content into multiple sub-contents according to the different security levels corresponding to the various contents within the first content. For example, if a certain content in the first content corresponds to a security level higher than a preset security level, that content can be divided into a sub-content from the first content, and the remaining content in the first content can be divided into another sub-content.

[0116] Please see Figure 14 , Figure 14 This application shows Figure 13The flowchart below illustrates step S420 of the method for displaying the shown content. Figure 14 The process shown will be described in detail, and the method may specifically include the following steps:

[0117] Step S421: After receiving the synchronous display operation, obtain the type of the first content.

[0118] In some implementations, after receiving a synchronization display operation, the electronic device can respond to the operation by obtaining the type of the first content. The type of the first content may include image type, text type, video type, etc., and is not limited thereto.

[0119] Step S422: If the type satisfies the preset type, the first content is split into multiple sub-contents and the multiple sub-contents are displayed on the first screen.

[0120] In some implementations, the electronic device may preset and store a preset type, which serves as the basis for determining the type of the first content. Therefore, in this embodiment, upon obtaining the type of the first content, the type of the first content can be compared with the preset type to determine whether the type of the first content satisfies the preset type. If the type of the first content satisfies the preset type, it indicates that the first content can be split, and the first content can be split into multiple sub-contents, which are then displayed on the first screen. If the type of the first content does not satisfy the preset type, it indicates that the first content cannot be split, and the first content can remain unsplit and be directly synchronized to the second screen for display.

[0121] Step S430: After receiving the selection operation for the plurality of sub-contents, select the target sub-content from the plurality of sub-contents.

[0122] In this embodiment, while displaying multiple sub-contents on the first screen, the electronic device can detect whether a selection operation for the multiple sub-contents has been received. If a selection operation for the multiple sub-contents is received, a target sub-content can be selected from the multiple sub-contents in response to the selection operation. The target sub-content may include at least one of the multiple sub-contents. If no selection operation for the multiple sub-contents is received within a preset time period, all of the first content can be synchronized to the second screen for display.

[0123] In some implementations, the electronic device may determine that it has received a selection operation for multiple sub-contents upon receiving a sixth target operation applied to the electronic device; or it may determine that it has received a selection operation for multiple sub-contents upon receiving a sixth target voice input to the electronic device, etc., without limitation.

[0124] Step S440: Display the first content on the first screen and the target sub-content on the second screen, and display the target sub-content displayed on the second screen as a thumbnail on the first screen.

[0125] In this embodiment, when the target sub-content is determined from multiple sub-contents, the target sub-content can be synchronized to the second screen for display, while other sub-contents in the first content (excluding the target sub-content) are not synchronized to the second screen (they are only displayed on the first screen). That is, the first content is displayed on the first screen and the target sub-content is displayed on the second screen, and the target sub-content displayed on the second screen is displayed as a thumbnail on the first screen, thereby enhancing the user's autonomy and protecting the user's privacy.

[0126] An embodiment of this application provides a method for displaying content, in which first content is displayed on a first screen, and after receiving a synchronous display operation, the first content is divided into multiple sub-contents and the multiple sub-contents are displayed. After receiving a selection operation for the multiple sub-contents, a target sub-content is selected from the multiple sub-contents, the first content is displayed on the first screen and the target sub-content is displayed on a second screen, and the target sub-content displayed on the second screen is displayed on the first screen as a thumbnail. Compared to Figure 1 The method for displaying the content shown in this embodiment can also selectively synchronize the content displayed on the first screen to the second screen for display, thereby enhancing the user's autonomy and improving the user experience.
