[0058] To make the objectives, technical solutions and advantages of the present disclosure clearer, the following will further describe the embodiments of the present disclosure in detail with reference to the accompanying drawings.

[0059] Unless otherwise defined, the technical terms or scientific terms used herein shall have the ordinary meanings understood by those of ordinary skill in the art to which the present disclosure pertains.

[0060] Figure 1 It is a schematic diagram of the front structure of a foldable display device provided by an embodiment of the present disclosure. Figure 2It is a schematic diagram of the back structure of a foldable display device provided by an embodiment of the present disclosure.

[0061] Referring to Figure 1 and Figure 2 , the foldable display device includes: a housing 101, a rotating shaft 102, a first display screen 103, and a second display screen 104.

[0062] The first display screen 103 has a bending area 1031, and a first area 1032 and a second area 1033 located on both sides of the bending area 1031. The area of the first area 1032 is larger than the area of the second area 1033.

[0063] The housing 101, the rotating shaft 102, and the second display screen 104 are all located on the back of the first display screen 103. The second display screen 104 is located in the second area 1033. The rotating shaft 102 is located in the bending area 1031 and is connected to the first display screen 103. The housing 101 and the second display screen 104 are rotatably connected through the rotating shaft 102.

[0064] Figure 3 It is a schematic diagram of the internal structure of a foldable display device provided by an embodiment of the present disclosure. Referring to Figure 3 , the foldable display device further includes: a battery 105.

[0065] The first area 1032 and the housing 101 form a first accommodation cavity 201, and the second area 1033 and the second display screen 104 form a second accommodation cavity 202. The battery 105 is located in the first accommodation cavity 201.

[0066] In the foldable display device provided by the embodiment of the present disclosure, an asymmetric folding device is formed by the housing, the rotating shaft, the first display screen, and the second display screen. The asymmetric folding device has two accommodation cavities with different sizes. Setting the battery in the larger accommodation cavity can ensure that the battery size is large enough. Compared with setting 2 small batteries in the two accommodation cavities of a symmetric folding device respectively, the battery energy density is improved, and thus the battery life is improved and the weight is reduced.

[0067] In addition, by setting the second display screen on the back of the second area of the first display screen, the second display screen covers the second area of the first display screen in the folded state and displays together with the first area, ensuring that there is enough display area in the folded state, thereby improving the user experience in the folded state.

[0068] Among them, when the overall battery capacity remains unchanged, using a single battery can reduce the increase in the volume of the battery structure parts caused by battery splitting and reduce the size of the battery core, thereby increasing the overall battery capacity of the machine and improving the battery life and weight of the whole machine.

[0069] The foldable display device in the embodiments of the present disclosure may be: any product or component with a display function, such as a mobile phone, a tablet computer, a television, a monitor, a laptop computer, a digital photo frame, a navigator, etc.

[0070] As Figure 1 shown, in the foldable display device provided by the embodiments of the present disclosure, both the first area 1032 and the second area 1033 of the first display screen 103 are rectangles.

[0071] The first area 1032 and the second area 1033 are spaced apart in the length direction. Therefore, the widths of the first area 1032 and the second area 1033 are equal, and the difference lies in the length. Thus, the area of the first area 1032 is larger than the area of the second area 1033, that is, the length of the first area 1032 is greater than the length of the second area 1033; the ratio of the area of the first area 1032 to the area of the second area 1033, that is, the ratio of the length of the first area 1032 to the length of the second area 1033.

[0072] In the embodiments of the present disclosure, the area ratio of the first area to the second area is 1.3 to 5.

[0073] In this implementation manner, adopting the above area ratio can, on the one hand, ensure that the first accommodation cavity has enough space to accommodate a large battery, and on the other hand, avoid the overall size of the folded device being too large due to too few folding parts.

[0074] As Figures 1 to 3 shown, the area ratio of the first area to the second area is 3.

[0075] Figure 4 And Figure 5 are schematic structural diagrams of another foldable display device provided by the embodiments of the present disclosure. As Figure 4 And Figure 5 shown, the area ratio of the first area to the second area is 3.

[0076] Figure 6 are schematic structural diagrams of another foldable display device provided by the embodiments of the present disclosure. As Figure 6 shown, the area ratio of the first area to the second area is 5.

[0077] Refer to Figure 1 again. The bending area 1031 is a rectangle, and the width of the bending area 1031 is equal to the width of the first area 1032 (the second area 1033). The length of the bending area 1031 is related to the bending radius of the first display screen 103, and the embodiments of the present disclosure do not limit this.

[0078] Refer to Figure 2 again. The rotating shaft 102 is a strip-shaped structure, and the embodiments of the present disclosure do not limit the material and size of the rotating shaft 102.

[0079] See again Figure 3 The foldable display device further includes: a first main board 106 and a second main board 107, and the size of the first main board 106 is larger than that of the second main board 107.

[0080] The rotating shaft 102 separates the first accommodation cavity 201 and the second accommodation cavity 202. The first main board 106 is located in the second accommodation cavity 202, and the second main board 107 is located in the first accommodation cavity 201.

[0081] In this implementation, the first main board with a larger size is arranged in the accommodation cavity without a battery, ensuring that there is enough space in the accommodation cavity to accommodate the main board; the second main board with a smaller size is arranged in the accommodation cavity with a battery, without affecting the setting of the battery. At the same time, setting two main boards can better arrange the circuit functions and simplify the circuit.

[0082] As Figure 3 shown, since the widths of the first accommodation cavity 201 and the second accommodation cavity 202 are quite similar, the widths of the above-mentioned battery 105, the first main board 106, and the second main board 107 are quite similar. However, in terms of length, the length of the battery 105 is greater than the length of the first main board 106, and the length of the first main board 106 is greater than the length of the second main board 107.

[0083] In the embodiments of the present disclosure, the first main board 106 may be a system main board, and the second main board 107 may be a charging board.

[0084] Among them, the system main board includes components such as a system-on-chip (SOC), a power module, a storage module, a display driving module, a touch driving module, a radio frequency module, a sensor module, and an audio module. The SOC communicates with the first display screen and the second display screen through two display interfaces (such as a Mobile Industry Processor Interface (MIPI)), and the SOC can control the switching between the main screen / secondary screen display according to requirements.

[0085] The charging board includes related devices such as a charging interface, a speaker (SPK), and a microphone (MIC). The battery and the charging board are connected to the system main board and peripheral devices in the second accommodation cavity through a flexible printed circuit (FPC).

[0086] In this implementation, the system main board with a larger size is arranged in the second accommodation cavity without a battery, and the charging board with a smaller size is arranged in the first accommodation cavity with a battery. And it is more convenient to arrange the charging circuit when the charging board and the battery are in one accommodation cavity.

[0087] As Figure 1 shown, the first region 1032 is located at the bottom of the first display screen 103, and the second region 1033 is located at the top of the first display screen 103.

[0088] Correspondingly, in Figure 3 , the first accommodation cavity 201 is located at the bottom of the foldable display device, and the second accommodation cavity 202 is located at the top of the foldable display device.

[0089] As Figure 3 shown, the second main board 107 is located on the side of the battery 105 away from the rotating shaft 102.

[0090] In the embodiment of the present disclosure, the second accommodation cavity 202 further includes circuit-related components such as a receiver (Receiver, RCV), a motor, and a noise reduction MIC.

[0091] In this implementation, the charging board is arranged at the bottom of the first accommodation cavity, that is, the bottom of the entire device, so as to facilitate the external arrangement of the charging interface.

[0092] In the embodiment of the present disclosure, the housing 101 includes a back shell and a middle frame. Among them, the back shell is located in the first region 1032.

[0093] In one implementation, the middle frame can be arranged around the edge of the first display screen for one week.

[0094] In another implementation, the middle frame can be arranged only at some positions on the edge of the first display screen (for example, only arranged at the top and bottom). Other positions (such as two sides) can be used to arrange components such as antennas.

[0095] Referring again to Figure 5 , the foldable display device further includes: a first antenna 301 and a second antenna 302.

[0096] The first antenna 301 is located on the side frame of the first accommodation cavity 201, and the second antenna 302 is located on the side frame of the second accommodation cavity 302.

[0097] Both the first antenna 301 and the second antenna 302 are connected to the system main board.

[0098] In this implementation, arranging the antenna on the side frame can provide space utilization rate and signal quality. In addition, since it is a foldable display device, the antennas are arranged on both sides of the rotating shaft 2 respectively, and the antennas will not be folded, which is convenient for the setting and assembly of the antennas.

[0099] Exemplarily, the first antenna 301 is arranged on at least one side frame of the first accommodation cavity 201, for example, arranged on two side frames of the first accommodation cavity 201 at the same time.

[0100] The second antenna 302 is arranged on at least one side frame of the second accommodation cavity 302, for example, arranged on 2 side frames of the second accommodation cavity 302 simultaneously.

[0101] In the embodiment of the present disclosure, the system main board is used to control the second antenna 302 to work when the foldable display device is in the unfolded state, and control the first antenna 301 to work when the foldable display device is in the folded state.

[0102] In this implementation, antennas are respectively configured on the side frames of the two accommodation cavities. When unfolded, the user holds the first accommodation cavity, and at this time, the second antenna in the second accommodation cavity is used for signal transceiver, without being affected or interfered by the user's hand. When folded, all of the second antenna overlaps with the first antenna (in the direction perpendicular to the display surface of the first display screen), but there is still a part of the first antenna that is not overlapped. In this case, the first antenna is used for signal transceiver, and the signal quality is better.

[0103] Exemplarily, the system main board can obtain the sensor data in the device, and the sensor is used to detect the state of the device; determine whether the device is in the unfolded state or the folded state according to the sensor data; control the second antenna to work and the first antenna not to work when the foldable display device is in the unfolded state; control the first antenna to work and the second antenna not to work when the foldable display device is in the folded state.

[0104] In the embodiment of the present disclosure, the radio frequency module includes a selection circuit, a spring sheet, and a spring type connector (pogo pin).

[0105] Among them, the selection circuit is used to select the antenna used for signal transceiver.

[0106] Exemplarily, the selection circuit is connected to the first antenna through a spring sheet; or, the selection circuit is connected to the second antenna through a spring type connector.

[0107] That is to say, the selection circuit is used to communicate with the first antenna through the spring sheet when the foldable display device is in the unfolded state.

[0108] When the foldable display device is in the folded state, it communicates with the second antenna through the spring type connector.

[0109] In this implementation, through the above components for connection, it can be ensured that the system main board can select different antennas to work when the foldable display device is in different states; among them, the two contacts of the spring connector are in contact conduction when folded and disconnected when unfolded; the spring sheet is in conduction when unfolded and disconnected when folded. That is to say, by folding and unfolding the foldable display device, different antennas can be connected in different states.

[0110] In other examples, the selection circuit can also be conducted with the first antenna or the second antenna through other connecting parts.

[0111] Refer to again Figure 2 、 Figure 4 and Figure 6 The second display screen 104 has a camera mounting hole, and the first display screen 103 is a full-screen display.

[0112] The foldable display device further includes: a camera 300. The camera 300 is located in the camera mounting hole. The relevant modules of the camera 300 are in the aforementioned second accommodation cavity 202.

[0113] In this implementation, the camera is arranged on the second display screen, the hole punching of the first display screen is cancelled to realize a full-screen display, and the display effect of the first display screen is ensured. At the same time, the resolution of the rear camera is usually better. After folding, take selfies or videos to improve the quality of selfies.

[0114] In other examples, a camera mounting hole can also be opened on the first display screen 103 to assemble the camera, while the second display screen 104 adopts a full-screen display. Or, both the first display screen 103 and the second display screen 104 are provided with camera mounting holes to assemble the camera.

[0115] In the embodiments of the present disclosure, the first display screen and / or the second display screen can be a liquid crystal display (LCD), an organic light-emitting diode (OLED) display screen, or other types of display screens.

[0116] In the embodiments of the present disclosure, the second display screen 104 can be a curved screen. For example, a deep curved screen with an edge area exceeding 45°. The edge of the second display screen 104 is used as a transition area to ensure the transition effect between the main screen and the secondary screen, making the simultaneous display of the main screen and the secondary screen more natural.

[0117] For example, the first display screen is a flexible OLED display screen, and the second display screen is an LCD curved screen.

[0118] In the embodiments of the present disclosure, when the foldable display device is in the unfolded state, the foldable display device is of a normal size. The second display screen around the rear camera of the foldable display device is used as an external screen for display, and the top end of the back of the foldable display device is a deep curved screen for display.

[0119] When the foldable display device is in the folded state, the first display screen is asymmetrically folded inwards by using a rotating shaft. After folding, the second display screen and the first area exposed by the folding of the first display screen cooperate for display. The first area is the main display area, and the second display screen is the secondary display area. In the asymmetric folding state, the user's usage scenarios can be expanded, including folding the camera to the front for selfies, and completing the interaction of different interfaces through user operations in the display area, etc.

[0120] Different from traditional straight display devices or symmetric folding display devices, the asymmetric folding display device provides users with a brand-new usage experience and interaction method due to its unique screen ratio and folding method, meeting the diverse needs of users.

[0121] Physically, the display ratio in the fully folded state of the whole machine is close to that in the unfolded state, improving the usage experience. Moreover, the crease is not in the middle main body position, and the display and touch are less affected when used in the unfolded state.

[0122] In the embodiment of the present disclosure, the foldable display device further includes a processor (not shown in the figure). The processor can be integrated on the aforementioned system motherboard. The processor can be the aforementioned SOC or other processors.

[0123] In the embodiment of the present disclosure, the processor can be used to control the display screens of the first display screen and the second display screen.

[0124] When the foldable display device is in the unfolded state, the first display screen and the second display screen do not affect each other. They can either display simultaneously, or one can display while the other is turned off, or both can be turned off simultaneously. And when they display simultaneously, they can display their respective contents.

[0125] When the foldable display device is in the folded state, in addition to being able to not affect each other like in the unfolded state, the first display screen and the second display screen can also display the same or related contents simultaneously, and through user interaction operations, the contents displayed on the first display screen and the second display screen are interacted.

[0126] In addition, in the folded state, a new user interface can be added to meet different application scenarios and improve the usage experience in the folded state.

[0127] In the embodiment of the present disclosure, when the mobile phone is in the folded state, the main display area can be used as a normal small screen. Combined with the secondary display area, the interface can show various different display styles. The secondary display area occupies a relatively small total area. Therefore, in addition to displaying completely and richly together with the main display area, the secondary display area is also suitable for displaying small functions such as the Dynamic Island, music player display, notification information, various cards, etc. And according to different touch states of the user, these functions can be switched between the main display area and the secondary display area.

[0128] The following illustrates the display of the foldable display device in the folded state through examples.

[0129] Figure 7 It is a schematic diagram of an application interface of a foldable display device provided by an embodiment of the present disclosure. As Figure 7As shown, the processor is used to control the second area 1033 of the first display screen 103 not to be displayed when the foldable display device is in the folded state, and the first area 1032 of the first display screen 103 displays the first application interface A.

[0130] The processor is used to control the second display screen 104 to display the second application interface B.

[0131] In this implementation manner, a part of the first display screen and the second display screen are respectively used as the main screen and the secondary screen when folded, ensuring the display effect in the folded state.

[0132] As Figure 7 shown, the first application interface A can be any application interface installed in the foldable display device. Similarly, the second application interface B can also be any application interface installed in the foldable display device.

[0133] When displaying, the first application interface A can be the complete interface of the application, and the second application interface B can be either the complete interface (shrunk) of the application, or a partial interface of the application, or the corresponding interface of the application as a small widget or a small card.

[0134] Figure 8 is a schematic diagram of the application interface of a foldable display device provided by an embodiment of the present disclosure. Compared with Figure 7 that, Figure 8 the application interface displayed on the second display screen 104 is different, and the application interface displayed on the first display screen 103 is the same.

[0135] In Figure 8 the shown interface, the processor is used to control the second display screen 104 to display the third application interface C.

[0136] As Figure 7 and Figure 8 shown, the first application interface A is a phone interface, the second application interface B is a map interface, and the third application interface C is a music software interface. The above interfaces are only examples and are not intended to limit the embodiments of the present disclosure.

[0137] Figure 7 and Figure 8 show schematic diagrams of the interfaces in the static state. The following describes the changes in the interfaces during user operations with reference to the drawings.

[0138] Figure 9 is a schematic diagram of the change of the application interface of a foldable display device provided by an embodiment of the present disclosure. Referring to Figure 9 , the processor is used to display an animation of the second application interface moving from the second display screen 104 to the first area of the first display screen 103 when detecting a sliding operation from the second display screen 104 to the first area of the first display screen 103.

[0139] After the sliding operation ends, a second application interface is displayed in the first area of the first display screen 103.

[0140] In this implementation, through the above operations, the application can switch the display between the main screen and the secondary screen, ensuring the display effect.

[0141] Since the area of the first area of the first display screen is larger than that of the second display screen, when the second application interface is displayed in the first area of the first display screen, the second application interface can be enlarged and displayed.

[0142] When a downward sliding operation is performed in the secondary display area, the interface displayed in the secondary display area will smoothly slide down through the deep curved screen at the top of the second display screen. At the boundary between the main and secondary display areas, that is, the deep curved surface, due to the height difference between the inward-folded main and secondary display areas, at this time, the cards will present a staggered "wave" effect in the display. When it completely slides into the main display area, it will be displayed according to the size ratio of the main display area. While sliding down, the secondary display area will select (for example, randomly or sequentially) one item from the application pool to continue displaying, including schedule, clock, music, etc.

[0143] Exemplarily, the processor initially displays the respective application interfaces on the first display screen and the second display screen; when a sliding operation of the user is detected, the second application interface is moved to the first display screen according to the original ratio, and a stepped application is selected for display on the second display screen; when the second application interface completely slides into the first display screen, it is enlarged proportionally at the blank space on the first display screen.

[0144] As Figure 9 shown, since the first application interface was originally displayed on the first display screen, after the second application interface is enlarged and displayed on the first display screen, the first application interface and the second application interface are arranged side by side.

[0145] In one example, the second application interface does not affect the original first application interface.

[0146] In another example, the second application interface squeezes the original first application interface, causing the first application interface to shrink.

[0147] As Figure 9 shown, during the process of the second application interface moving from the second display screen to the first display screen, an animation of the third application interface appearing is displayed on the second display screen. When the second application interface moves out of the second display screen, the second application interface displays the complete third application interface.

[0148] Figure 10 is a schematic diagram of the change of the application interface of another foldable display device provided by an embodiment of the present disclosure. Contrary to the process Figure 9 shown, in Figure 10In it, the process of the second application interface sliding from the first display screen to the second display screen is shown.

[0149] The processor is used to display an animation of the second application interface moving from the first area of the first display screen 103 to the second display screen 104 when a sliding operation from the first area of the first display screen 103 to the second display screen 104 is detected.

[0150] After the sliding operation ends, the second application interface is displayed on the second display screen 104.

[0151] In this implementation manner, through the above operations, the application can be switched between the secondary screen and the main screen to ensure the display effect.

[0152] Since the area of the first area of the first display screen is larger than that of the second display screen, when the second application interface is displayed on the second display screen, the second application interface can be shrunk and displayed.

[0153] In part, the principle and process are the same as Figure 9 On the contrary, it will not be elaborated here.

[0154] In Figure 9 and Figure 10 above, the aforementioned sliding operation is for the second application interface.

[0155] In one example, the movement of the second application interface will not affect the original first application interface.

[0156] In another example, the movement of the second application interface will affect the first application interface, causing the first application interface to be enlarged.

[0157] As Figure 10 shown, during the process of the second application interface moving from the first display screen to the second display screen, the second display screen displays an animation of the third application interface moving out. When the second application interface moves out of the first display screen, the third application interface moves out of the second display screen.

[0158] In addition, the application interfaces of the applications in the foldable display device can not only move between the first display screen and the second display screen, but also be switched on the second display screen through a sliding operation.

[0159] For example, in Figure 9 above, through a downward sliding operation on the first application interface, the first application interface is moved from the second display screen to the first display screen. If the upward sliding operation is performed on the first application interface, the first application interface displayed on the second display screen can be switched to the third application interface, and the display of the first display screen is not affected during this process.

[0160] Figure 11It is a schematic diagram of the application interface change of another foldable display device provided by an embodiment of the present disclosure. As Figure 11 shown, the processor is configured to replace the second application interface with the third application interface when a sliding operation on the second display screen 104 is detected.

[0161] In this implementation, the free switching of applications on the secondary screen is achieved through the above operations.

[0162] In the folded state, in addition to being able to control the position and switching of the application interface, the use experience of applications such as taking pictures, photos, and videos can also be improved through the second display screen.

[0163] In this implementation, in the secondary display area, when the user swipes up, the displayed content can be changed, and the processor can randomly select or sequentially select from the application pool.

[0164] Figure 12 It is a schematic diagram of taking pictures of a foldable display device provided by an embodiment of the present disclosure. As Figure 12 shown, when the foldable display device is in the folded state and the foldable display device is performing a shooting task, the processor is configured to display a shooting screen in the first area of the first display screen 103 and display shooting prompts on the second display screen 104.

[0165] In this implementation, shooting is performed through the above operations to ensure the convenience of shooting and the shooting effect, and the function of the secondary screen is fully utilized.

[0166] The above shooting can be self-taken or video call, etc.

[0167] The shooting prompt can be provided with appropriate suggestions by artificial intelligence (AI) according to the imaging effect and environmental monitoring, such as: suggesting lighting, suggesting getting closer, etc.

[0168] Exemplarily, when the processor detects that the distance between the user and the screen is less than the first threshold, the user is prompted to move away from the lens, for example, displaying "It is recommended to move away from the lens".

[0169] Exemplarily, when the processor detects that the distance between the user and the screen is greater than the second threshold, the user is prompted to get closer to the lens, for example, displaying "It is recommended to get closer to the lens".

[0170] Wherein, the first threshold is less than the second threshold, and the values of the first threshold and the second threshold are not limited in the embodiments of the present disclosure.

[0171] Exemplarily, when the processor detects that the user's face is not entirely within the lens, the user is prompted to adjust the lens orientation, for example, displaying "It is recommended to face the lens directly".

[0172] Figure 13It is a schematic diagram of an application interface of a foldable display device provided by an embodiment of the present disclosure. As Figure 13 shown, the processor is used to control the second area of the first display screen 103 not to be displayed when the foldable display device is in a folded state, and the first area of the first display screen 103 and the second display screen 104 display the same application interface.

[0173] In this implementation manner, when the second display screen adopts a curved screen, when the first area of the first display screen and the second display screen display the same picture, the picture transitions to the first display screen more naturally at the edge of the second display screen.

[0174] As Figure 13 shown, the application interface can be a photo application interface or a video application interface.

[0175] Figure 14 It is a schematic diagram of the change of the application interface of another foldable display device provided by an embodiment of the present disclosure. Refer to Figure 14 , the application interface can be only displayed in the first area of the first display screen. The processor is used to simultaneously display the application interface in the first area of the first display screen 103 and the second display screen 104 when the foldable display device is in a folded state and an upward sliding operation for the application interface is detected.

[0176] In this implementation manner, the same picture is displayed in the first area of the first display screen and the second display screen through an upward sliding operation, and the application interface can be freely scaled on the two screens.

[0177] Although the above sliding operation and Figure 10 are both upward sliding operations. But the difference between this sliding operation and Figure 10 is that Figure 10 there are other applications in the first display screen, and at this time the sliding operation is used to move the application interface to the second display screen; while Figure 13 there are no other applications in the first display screen, and at this time the sliding operation is used to enlarge the application interface to the first display screen and the second display screen.

[0178] Among them, the upward sliding operation refers to a sliding operation from the first display screen to the second display screen direction, and the downward sliding operation refers to a sliding operation from the second display screen to the first display screen direction.

[0179] In addition to considering the situation of applications in the first display screen, in other examples, it can also be based on the application type. For example, when the application is an application such as a map or music, the Figure 10 way is adopted. When the application is an application such as a photo or video, the Figure 13 way is adopted.

[0180] Figure 14In addition to being implemented through a sliding operation, the function can also be achieved through system settings. For example, when the foldable display device is in a folded state and the processor detects that the screen expansion function in the system settings is enabled, the application interface is simultaneously displayed in the first area of the first display screen 103 and the second display screen 104.

[0181] Taking a video as an example, in the folded state, when watching a video, the user can select screen expansion in the system settings by themselves, that is, expand the video content played in the main display area, and a part of it is displayed in the secondary display area. There is a camera module in the secondary display area, which may interfere with the main content of the video and the display is incomplete. In the case of extended video playback, at the boundary between the main and secondary display areas, due to the height difference caused by folding and the deep curved screen display at the edge of the outer screen, a dynamic "wave" effect will also be displayed in this area.

[0182] In the embodiments of the present disclosure, in addition to performing a sliding operation up and down, a left - right sliding operation can also be performed on the application interface.

[0183] Figure 15 is a schematic diagram of the change of the application interface of another foldable display device provided by the embodiments of the present disclosure. Refer to Figure 15 , the processor is configured to, when the foldable display device is in a folded state and detects a left or right sliding operation on the application interface, shrink the main body of the application interface (such as the screen or the main interface), and display the information and / or function interface for the application interface.

[0184] In this implementation manner, by sliding left and right to shrink the main body of the application interface and display the information and / or function interface for the application interface, it is convenient for the user to understand the application information and / or convenient for the user to perform editing.

[0185] That is to say, in this implementation manner, by sliding left and right to shrink the application interface, at this time, an information interface, or a function interface, or an information and function interface is generated specifically.

[0186] Such as Figure 15 As shown, when it is the application interface for a video, an information interface can be generated below to introduce the information of the video. A function interface can be generated on the right side, and the function interface can include multiple editing buttons, such as matte extraction, translation, subtitles, etc.

[0187] The user slides inwards from the right - hand edge of the main display area, causing the video screen to shrink proportionally, which can avoid the camera and ensure the integrity of the video content. At the same time, the detailed information of the video is displayed in the vacant area below the main display area, and background applications, AI - related functions, etc. are displayed in the vacant area on the right side.

[0188] In addition, in other examples, information and / or a function interface can also be arranged on the second display screen, and the main body of the application interface can be shrunk to the first display screen.

[0189] Figure 16 FIG. is a schematic diagram of the change of the application interface of another foldable display device provided by an embodiment of the present disclosure. Refer to Figure 16 , the processor is configured to, when the foldable display device is in a folded state and an upward sliding operation on the application interface is detected, shrink the main body of the application interface (such as a screen or a main interface), display the main body of the application interface on the first display screen, and display the shrunk main body of the application interface on the second display screen.

[0190] In this implementation manner, by shrinking the main body of the application interface to the second display screen, other applications can be switched on the first display screen later, realizing seamless application switching.

[0191] Such as Figure 16 shown, the application can be a video call, a conference, a game, or other applications with high requirements for real-time performance.

[0194] 402: Control the second display screen to display the second application interface.

[0195] In this implementation manner, a part of the first display screen and the second display screen serve as the main screen and the secondary screen respectively when folded, ensuring the display effect in the folded state.

[0196] Optionally, this method may further include:

[0197] When a sliding operation from the second display screen to the first area of the first display screen is detected, display an animation of the second application interface moving from the second display screen to the first area of the first display screen.

[0198] After the sliding operation ends, display the second application interface in the first area of the first display screen.

[0216] Optionally, the method may further include:

[0217] When the foldable display device is in a folded state and a left or right swipe operation on the application interface is detected, shrink the main body of the application interface (such as the screen or the main interface), and display information and / or a function interface for the application interface.

[0218] In this implementation, by swiping left and right to shrink the main body of the application interface and display information and / or a function interface for the application interface, it is convenient for the user to understand the application information and / or convenient for the user to perform editing.
