The foldable display screen shown in fig. 2a is in a flattened configuration and the foldable display screen shown in fig. 2b is in a folded configuration. The foldable display screen shown in fig. 2c is in an unfolded configuration. As shown in fig. 2b and 2c, the angle of the plane of the first display area and the plane of the second display area rotated around the bending portion as the axis can be referred to as the opening angle of the foldable display screen in the folded state as the reference state. In the embodiment of the application, the opening angle of the foldable display screen can be between 0 degree and 180 degrees, and can also be between 0 degree and 360 degrees.

(2) Flattened, folded and unfolded configurations

As shown in FIG. 2a, in the flat-out state, the angle between the plane of the first display area and the plane of the second display area, also called the opening angle of the foldable display screen is 180 ° ± β, i.e. the first display area and the second display area are in the same plane, and the first display area and the second display area are distributed in a flat-out state, the first display area and the second display area form a continuous display area through the bending part, the electronic device can display the user interface in the display area formed by the first display area and the second display area, in this state, the electronic device can display the user interface in a full screen, wherein β is a non-negative angle value, such as 2 ° and 0 °.

As shown in fig. 2b, in the folded configuration, an angle between a plane of the first display area and a plane of the second display area is also called: the opening angle of the foldable display screen may be 0 ° + γ, for example an opening angle of 0 °. Where γ is a non-negative angle value, e.g., 3 °, 0 °.

As shown in FIG. 2c, in the unfolded state, the angle between the plane of the first display region and the plane of the second display region is also called as the opening angle of the foldable display screen α, the opening angle is the angle of the plane of the first display region and the plane of the second display region rotated around the bending part as the axis with reference to the folded state shown in FIG. 2 b. illustratively, the value of the opening angle α may include γ < α < 180 °, for example, the opening angle α in the folded state may include 30 °, 45 °, 90 °, 150 °, and so on.

Application scenarios related to embodiments of the present application are described below. When the display screen is in the folded state or the unfolded state, the folding screen device can display the user interface on only one of the first display area and the second display area. Specifically, when the display screen is shown in the folded configuration in fig. 2b and the display screen is shown in the unfolded configuration in fig. 2c, the folding screen apparatus may display the user interface on only one of the first display area and the second display area. The exemplary folded screen device displays the user interface only in the first display area, and the second display area may be dismissed and not displayed. The folded-screen device may select one of the first display region and the second display region to display the user interface based on a pose of the folded-screen device. Wherein the pose of the folded screen device may comprise a change in orientation of the display area. For example: the first or second display area is oriented (e.g., facing up or down), the first display area faces the face of a person, the second display area faces the face of a person, etc.

When the display screen is in the folded configuration, the folded screen device is correspondingly in the folded configuration.

When the display screen is in the expanded configuration, the folding screen device is correspondingly in the expanded configuration.

When the display screen is in the flat-out configuration, the folding screen device is correspondingly in the flat-out configuration.

Several examples of methods of determining the pose of a folding screen device are described below.

(1) Determining a pose of a folding screen device using a gyroscope sensor

The folded screen device may determine the angular velocity of the folded screen device in three-dimensional space via a gyro sensor, thereby determining the angle of rotation of the folded screen device relative to a direction (e.g., horizontal). The folding screen device can determine whether the first display area faces the face or the second display area faces the face according to the corner, and select the display area facing the face in the first display area and the second display area to display the user interface. In the embodiment of the present application, the specific principle of measuring the posture of the folding screen device by using the gyroscope sensor may refer to the description of fig. 13a to 13b, and details are not repeated here.

(2) Determining the pose of a folding screen device using the state of a display area being held

Generally, a display area facing away from a human face is continuously touched due to a holding habit. Accordingly, a state in which the first display area and the second display area are touched may also be detected using the pressure sensor and/or the touch sensor. The display area which is continuously touched can be identified as the display area which faces away from the human face, so that the folding screen device determines the display area which faces the human face from the first display area and the second display area, and displays the user interface through the display area which faces the human face. A specific principle of measuring the posture of the folding screen device with the display area held may refer to the description of the pressure sensor in fig. 11, and will not be described herein.

(3) Determining the posture of a folding screen device by using a face image acquired by a camera

In another possible implementation, cameras may be mounted on both the body where the first display area is located and the body where the second display area is located. The camera that first display area corresponds and the camera that first display area corresponds all can gather the image. And if the face image is acquired, the corresponding display area faces to the face. The folding screen device selects the display area facing the face to display the user interface. For example, when a camera corresponding to the first display area acquires a face image, an image acquired by the second display area does not contain the face image, and the folding screen device determines that the first display area faces the face.

In the embodiment of the application, the folding screen device may determine the posture of the folding screen device according to any one or more of the above methods, and select a display area facing the face to display the user interface according to the posture. The folding screen device can detect the posture of the folding screen device in real time, and switches a display area for displaying a user interface according to the posture. For example, in the folded state, the first display area faces the face of a person in the posture of the folding screen device, the folding screen device displays the user interface in the first display area, and the second display area is closed. When the posture of the folding screen device is changed, for example, the first display area faces the face of a person, the second display area faces the face of the person, the folding device closes the first display area, opens the second display area and displays the user interface in the second display area. The function can be called as a function of automatically switching the display area, that is, the first display content displayed in the first display area is switched to be displayed in the second display area, and after the first display content is switched to be displayed in the second display area, the second display area and the first display area can simultaneously display the first display content; the first display area may also be turned off after the first display content is switched to be displayed in the second display area.

In the embodiment of the application, when the folding screen device detects that the display area facing the face changes, that is, the posture of the folding screen device changes, the folding screen device determines that the deflection angle of the folding screen device is larger than the deflection angle threshold. For example, when the folding screen device detects that the first display area faces the face and the second display area faces the face through the sensor, it is detected that the deflection angle of the folding screen device is greater than the deflection angle threshold, that is, the first display area faces the face and is turned over to the second display area faces the face.

For example, please refer to fig. 1a and 1b, and fig. 1a and 1b are schematic functional diagrams of an automatic switching display area according to an embodiment of the present disclosure. As shown in fig. 1a, when the position of the folding screen device is detected such that the first display area faces a human face, the folding screen device displays the user interface 90 (e.g., the main screen interface 90) only in the first display area, and the second display area may be closed and not displayed. As shown in fig. 1b, when it is detected that the gesture of the folding screen device is turned from the first display area facing upward, the second display area facing downward to the first display area facing downward, and the second display area facing upward, the folding screen device may switch the user interface 90 displayed on the first display area to the second display area for display. The folding device may close the first display area, open the second display area, and display the user interface 90 in the second display area. Thus, convenience of display can be improved.

In the embodiment of the application, the sensor detects that the first display area faces the face and includes that the first display area faces upwards, and the sensor detects that the second display area faces the face and includes that the first display area faces downwards (the second display area faces upwards). When the fact that the first display area faces the face is switched into the second display area faces the face is detected, the folding screen device determines that the deflection angle of the folding screen device is larger than the deflection angle threshold value, and the first display area faces the face and is switched into the second display area faces the face. In this embodiment of the application, the flipping is not limited to flipping the first display region upward to turn the first display region downward, but also includes flipping the first display region left to turn the first display region right, which is not limited in this embodiment of the application.

However, when the folding screen device displays a scene for scanning the two-dimensional code, for example, the first display area displays a two-dimensional code interface, the first display area faces away from the face of the user for another device to scan the two-dimensional code due to the user flipping the device, and the folding screen device switches the two-dimensional code interface to the second display area for display. Referring to fig. 3a and 3b, fig. 3a and 3b are schematic views of a scene in which a two-dimensional code is displayed for scanning by a folding screen device according to an embodiment of the present application. As shown in fig. 3a, the folding screen device displays a two-dimensional code interface 10. When the user turns over the device so that the first display area faces away from the face of the user for another device to scan the two-dimensional code, as shown in fig. 3b, the folded screen device switches the two-dimensional code interface 10 to the second display area for display as it is detected that the deflection angle of the folded screen device is greater than the deflection angle threshold. Like this, show the two-dimensional code through the display area towards the user all the time, be unfavorable for folding screen equipment to show the two-dimensional code to another equipment (for example bar code scanner), reduced the convenience of scanning the two-dimensional code.

In the display method provided by the embodiment of the application, the display screen is in a folded state or an unfolded state, and when it is detected that the folding screen device is switched to a specific user interface, such as a two-dimensional code interface, a picture interface or a video interface, the folding screen device can close the function of automatically switching the display area. That is, the folded-screen device does not switch the display area for displaying the particular user interface regardless of the posture of the folded-screen device and regardless of the states in which the first display area and the second display area are touched. For example, during the display of the two-dimensional code interface by the folding screen device, the two-dimensional code interface is displayed only on the first display area, and the two-dimensional code interface is not switched to be displayed on a different display area with the turning of the folding screen device.

For example, when the folding screen device displays the two-dimensional code interface on the first display area, the folding screen device closes the function of automatically switching the display area, that is, when the user turns over the device so that the first display area faces away from the face of the user for another device to scan the two-dimensional code, the folding screen device still displays the two-dimensional code interface on the first display area.

According to the two-dimension code display method, when the folding screen device detects that the two-dimension code interface is switched, the function of automatically switching the display area is closed. Like this, be convenient for the user upset folding screen equipment make another equipment scan two-dimensional code, improved the convenience.

In another possible implementation manner, when switching to the two-dimensional code interface, the folding screen device may display the two-dimensional code interface on both the first display area and the second display area. No matter how the user overturns the folding screen device or changes the holding state of the folding screen device, the first display area and the second display area of the folding screen device both display a two-dimensional code interface for another device to scan a two-dimensional code, and convenience is improved.

In other embodiments of the present application, the function of automatically switching the display area is turned off according to the specific user interface to which the display screen is switched when the display screen is in the folded state. The embodiment of the application is not limited to be applied to a folding screen device comprising a foldable display screen. It can be understood that the present application is described by taking a folding screen device as an example, but is not limited to the folding screen device, and may also be a multi-screen device in which both front and back sides of the device include a display screen, which is not limited in the embodiment of the present application.

The user interface provided by the embodiments of the present application is described below. The user interfaces related to the embodiment of the application are all user interfaces of the display screen of the folding screen device in a folding state or an unfolding state.

In this embodiment, the two-dimension code interface 10 on the folding screen device may be a two-dimension code payment interface provided by each application, for example, a two-dimension code interface for receipt and payment of a WeChat application and a Payment treasure application, and for example, a two-dimension code payment interface for a Huacheng wallet application. And the other device can scan the two-dimensional code payment interface, so that account transaction is carried out between the device and an account logged in by the application on the folding screen device. The other device may be a desktop or mobile barcode scanner device, or may be an electronic device such as a smartphone or tablet. When the two-dimensional code interface 10 is switched, the folding screen device can close the function of automatically switching the display area. That is, the folded-screen device does not switch the display area for displaying the particular user interface regardless of the position of the folded-screen device. For example, when switching to the two-dimensional code interface 10, if the two-dimensional code interface is currently displayed on the first display area, the folding screen device is fixed on the first display area to display the two-dimensional code interface 10, and the second display area is closed, so that the two-dimensional code interface is not switched to the second display area to display. In another possible embodiment of the present application, when switching to the two-dimensional code interface 10, the folding screen device may display the two-dimensional code interface 10 in both the first display area and the second display area.

In the embodiment of the present application, the two-dimensional code interface 10 is introduced by taking a two-dimensional code payment interface in the wechat application as an example. The following describes a two-dimensional code payment interface in the wechat application according to the embodiment of the present application. Referring to fig. 4a to 4h, fig. 4a to 4h are schematic diagrams of some user interfaces provided in an embodiment of the present application.

As shown in fig. 4a, when the foldable display screen of the folding screen device is in the folded configuration, the display screen includes a first display area and a second display area. The first display area may display the user interface 20, which user interface 20 may be a user interface of a WeChat application. The second display area may be turned off not to be displayed. Application 1 in fig. 1a may be an icon 206 of a WeChat application. In response to a touch operation applied to the WeChat icon 206 on the home screen interface shown in FIG. 1a, the folded screen device may display the user interface 20. When the user interface 20 is displayed, the folding screen device may select one display region from the first display region and the second display region to display the user interface 20 according to the posture of the folding screen device. For example, when the first display area faces a human face, the user interface 20 is displayed in the first display area and the second display area is closed. When the pose of the folded-screen device changes (e.g., the folded-screen device is flipped from the first display area facing the face to the second display area facing the face), the folded-screen device may change the display area for displaying the user interface 20, close the first display area, open the second display area, and display the user interface 20 in the second display area.

As shown in fig. 4a, the user interface 20 may include: menu controls ("WeChat" 201, "Address" 202, "discover" 203, "I" 204), content display area 205. The displayed content in the content display area corresponding to different menu controls is different. The currently selected menu control shown in FIG. 4a is "WeChat" 201. That is, the content displayed in the content display area 205 is the content under the "WeChat" 201 menu. Wherein:

the content display area 205 contains a contact list 2051, an add control 2052. The contact list 2051 contains a plurality of contacts for message interaction, voice paging, etc. with the plurality of contacts.

In response to a user operation, such as a touch operation, acting on the add control 2052, the folding screen device displays a selection box 2053. Selection box 2053 may include an initiate group chat option 2053a, an add friends option 2053b, a sweep option 2053c, a collect payment option 2053d, and a help and feedback option 2053 e.

Where the initiate group chat option 2053a is used to initiate a group chat to a plurality of contacts. Add friends option 2053b is used to add a new contact. The scan option 2053c is used to turn on the function of scanning the two-dimensional code. Help and feedback options 2053e for feeding back user opinions.

In response to a user operation, such as a touch operation, applied to the receipt and payment option 2053d, the folding screen device displays the two-dimensional code interface 10. When the fact that the folding screen device is switched to the two-dimension code interface 10 is detected, if the two-dimension code is displayed on the first display area at present, the folding screen device is fixed on the first display area to display the two-dimension code interface 10, the two-dimension code cannot be switched to the second display area to be displayed due to the change of the posture of the folding screen device, for example, when the first display area faces upwards, the first display area displays the two-dimension code, the folding screen device deflects, the first display area is turned from the upwards to the downwards, the first display area continues to display the two-dimension code, and the two-dimension code originally displayed in the first display area cannot be switched to other display areas to be displayed due to the fact that the first display area is turned from the upwards to the downwards.

In this embodiment, before the foldable screen device deflects, the interface displayed in the first display area may be the first display interface. For example, a first display area displayed by the folding screen device may contain a two-dimensional code interface before the folding screen device is deflected. When the folding screen device detects that the deflection angle of the electronic device is larger than the deflection angle threshold value through the sensor, the folding screen device can display the two-dimensional code interface through the first display area. If the first display interface comprises a two-dimensional code interface, when it is detected that the deflection angle of the electronic device is greater than the deflection angle threshold, displaying the two-dimensional code interface through a first display area may include the following conditions: the two-dimensional code interface is displayed only through the first display area, namely the two-dimensional code interface 10 is fixedly displayed on the first display area, and the two-dimensional code is not switched to the second display area to be displayed due to the change of the posture of the folding screen device. And 2, simultaneously displaying the two-dimensional code interface through the first display area and the second display area.

If the first display area displayed by the folding screen device does not contain the two-dimensional code interface, after the folding screen device detects that the folding screen device is turned over from the first display area facing the face to the second display area facing the face through the sensor, the folding screen device can respond that the detected deflection angle of the folding screen device is larger than the deflection angle threshold value, and display the first display interface through the second display area.

As shown in fig. 4b, the two-dimensional code interface 10 may include: prompt 101, two-dimensional code area 102, two-dimensional code collection option 103, group collection option 104, face-to-face red envelope option 105, and return control 106. Wherein the prompt 101 may display "collect payment". The two-dimensional code and barcode displayed in the two-dimensional code area 102 may be scanned by another device to perform a payment transaction to an account corresponding to the other device. Two-dimensional code receipt option 103 may be used to display a receipt two-dimensional code for scanning by another device to receive a payment transaction for an account of the other device. The group checkout option 104 is used to initiate checkout to contacts in the group chat. The face-to-face red envelope option 105 is used to display a red envelope two-dimensional code for scanning by another device to conduct a payment transaction to an account of the other device. The return control 106 is used for returning to the upper level interface of the two-dimensional code interface 10. In response to a user operation acting on the return control 106, the fold screen device may display the user interface 20.

When switching to the two-dimensional code interface 10 is detected, if the two-dimensional code interface 10 is currently displayed on the first display area, the folding screen device is fixed on the first display area to display the two-dimensional code interface 10. No matter what posture the folding screen device is in, and no matter the state that the first display area and the second display area are touched, the folding screen device displays the two-dimensional code interface 10 on the first display area, and the two-dimensional code is not switched to the second display area to be displayed due to the change of the posture of the folding screen device. As shown in fig. 4c, the second display area may be closed. The user can overturn the equipment and make first display area back to user's face for bar code scanner scanning two-dimensional code, has improved the convenience that folding screen equipment shows the two-dimensional code to bar code scanner.

In another possible implementation manner, when switching to the two-dimensional code interface 10, the folding screen device may display the two-dimensional code interface 10 on both the first display area and the second display area. As shown in fig. 4d, the two-dimensional code interface 10 displayed on the second display area may be scanned by a scanner. In another implementation, the user may turn the device such that the first display area faces away from the user's face for the scanner to scan the two-dimensional code. Then no matter how the user overturns the folding screen equipment, or changes the holding state of the folding screen equipment, the two-dimensional code interface is all shown in the first display area and the second display area of the folding screen equipment, and the two-dimensional code is scanned by the code scanner, so that the convenience is improved.

In another possible implementation manner, the display screen is in a folded state or an unfolded state, and when the first display area displays the two-dimensional code interface 10, the folding screen device may display a control on the two-dimensional code interface 10, where the control may respond to a user operation, so that the folding screen device closes a function of automatically switching the display areas.

Specifically, as shown in fig. 4e, when the two-dimensional code interface 10 is switched to, the first display area may display the two-dimensional code interface 10, and the folding screen device may display a control 1011 on the two-dimensional code interface 10. The second display area may be closed. The folding screen device can open the function of automatically switching the display area. Control 1011 may prompt "click on a fixed display area". At this time, the function of automatically switching the display area on the folding screen device is still turned on, that is, the folding screen device can switch the display area for displaying the user interface 10 according to its posture. In response to a user operation acting on control 1011, the folding screen device may turn off the functionality that automatically switches display areas. After the function of automatically switching the display area is turned off, no matter what posture the folding screen device is in, the folding screen device does not switch the display area for displaying the two-dimensional code interface 10. For example, in response to a user operation acting on the control 1011, if the two-dimensional code interface 10 is currently displayed on the first display area, the folding screen device is fixed on the first display area to display the two-dimensional code interface 10, keeps the second display area closed, and does not switch to the second display area for display.

In one possible embodiment, when a first display interface is displayed through a first display area, a prompt message is displayed on the first display interface, and in response to a user operation on the prompt message, the first display interface is displayed through a second display area, or the first display interface is simultaneously displayed through the first display area and the second display area. When the first display interface is displayed through the first display area and the second display area simultaneously, the interfaces displayed by the first display area and the second display area can be the same, or the first display interface can be displayed through the combination of the first display area and the second display area.

In a possible implementation, when a first display interface including a characteristic user interface (e.g., a two-dimensional code, a video playing interface, a graphical interface, or the like) is displayed through a first display area, a prompt message is displayed on the first display interface, and in response to a user operation applied to the prompt message, the first display interface is displayed through a second display area, or the first display interface is simultaneously displayed through the first display area and the second display area. When the first display interface is displayed through the first display area and the second display area simultaneously, the interfaces displayed by the first display area and the second display area can be the same, or the first display interface can be displayed through the combination of the first display area and the second display area.

As shown in fig. 4f, in response to a user operation acting on control 1011, the folding screen device may display control 1012 on two-dimensional code interface 10. Control 1012 may prompt "click to automatically switch display regions". The control 1012 is used to restart the function of automatically switching the display area.

In other possible implementations of the present application, the display screen is in a folded configuration or an unfolded configuration, and when the first display area displays the two-dimensional code interface 10, the folded screen device may display the first control in the first display area. The first control may be responsive to a user operation to cause the folding screen device to display the two-dimensional code interface 10 in the second display area. Or the control can respond to the user operation, so that the folding screen device displays the two-dimensional code interface 10 in the first display area and the second display area. The first control may prompt "click on single screen display". The first control is the second prompt message in this embodiment of the application, and in response to a user operation acting on the second prompt message, the folding screen device displays the specific user interface (for example, a two-dimensional code interface) through the second display area. In another possible implementation, in response to a user operation on the second prompt message, the folding screen device displays the particular user interface through the first display area and the second display area.

Like this, when first display area was towards the people's face, the user can touch this control for folding screen equipment shows the two-dimensional code interface at the second display area, need not user's upset folding screen equipment, and the two-dimensional code interface that the second display area shows can be scanned by the scanner, thereby has improved the convenience of sweeping the sign indicating number.

Optionally, when the two-dimensional code interface 10 is switched to, the folding screen device may display a control on the two-dimensional code interface 10, where the control may respond to a user operation, so that the folding screen device displays the two-dimensional code interface 10 in both the first display area and the second display area. Specifically, as shown in fig. 4g, when the two-dimensional code interface 10 is switched to, the first display area may display the two-dimensional code interface 10, and the folding screen device may display a control 1013 on the two-dimensional code interface 10. The second display area may be closed. Control 1013 may prompt "click on double screen display". At this time, the function of automatically switching the display area on the folding screen device is still opened. In response to a user operation applied to control 1013, the folding screen device may display two-dimensional code interface 10 in both the first display area and the second display area. That is, the two-dimensional code interface 10 is displayed in the first display area and the second display area by the folding screen device no matter what posture the folding screen device is in.

As shown in fig. 4h, in response to a user operation acting on control 1013, the folding screen device may display control 1014 on two-dimensional code interface 10. Control 1014 may prompt "click on single screen display". Control 1014 is used to resume the state displayed in the first display region. After the state displayed in the first display region is restored, the folding screen device may still turn on the function of automatically switching the display regions.

In the two-dimensional code display interfaces shown in fig. 4e to 4h, when the two-dimensional code interface is displayed, the display area function is automatically switched, and the function of simultaneously displaying the user interface in the first display area and the second display area may be turned on or off by a user operation. Therefore, the user can automatically switch the display area function on and off according to the self requirement, and the convenience is improved. It can be understood that, in the embodiment of the present application, the two-dimensional code interface 10 is described as an example of a two-dimensional code payment interface in the wechat application, but the two-dimensional code interface is not limited in the embodiment of the present application. In other embodiments of the present application, the two-dimensional code interface 10 may also be a two-dimensional code interface provided by an application that contains personal information. The other device can scan the two-dimensional code interface, so that friends can be added and recommended according to the personal information obtained through scanning. For example, a two-dimensional code interface corresponding to personal business cards of WeChat and Payment treasures.

In other embodiments of the present application, the two-dimensional code interface 10 may also be an interface containing information of a certain account, information of a certain webpage, and information of a certain commodity. When the two-dimensional code interface 10 contains certain account information, another device scans the two-dimensional code interface 10 and can open a certain specific conversation window, for example, another device scans the two-dimensional code interface 10 corresponding to a certain public number in the wechat application of the folding screen device and can open the conversation window of the public number. For another example, when the two-dimensional code interface 10 contains information of a certain webpage, another device scans the two-dimensional code interface 10 displayed by the folding screen device, and the webpage corresponding to the two-dimensional code interface 10 can be opened by the browser 1011. For another example, when the two-dimensional code interface 10 contains information of a certain commodity, another device scans the two-dimensional code interface 10 displayed by the folding screen device, and a shopping interface corresponding to the two-dimensional code interface 10 can be opened through a shopping application.

The two-dimensional code interface 10 in the embodiment of the present application is not limited to the above example, and may also be another two-dimensional code interface, such as a car code, which is not limited in the embodiment of the present application.

In some embodiments of the present application, when the foldable display screen of the foldable screen device is in the folded state, the foldable display screen includes a first display area and a second display area, the two-dimensional code interface is displayed through the first display area, the function of automatically switching the display areas is turned off, and after the two-dimensional code interface is fixedly displayed on the first display area, the function of automatically switching the display areas is turned back on in response to a user operation. After the function of automatically switching the display areas is started, the folding screen device can detect the posture of the folding screen device, and one display area is selected from the first display area and the second display area to display the two-dimensional code interface 10. Specifically, referring to fig. 5a to 5c, fig. 5a to 5c are schematic views of some user interfaces provided in the embodiments of the present application.

As shown in fig. 5a, the two-dimensional code interface 10 may further include a prompt control 107 that prompts "fix display area, click to resume …". In response to a user operation acting on the prompt control 107, the fold screen device may display a selection box 108. The selection box 108 may include an option 1081, an option 1082, an option 1083, a determination control 1084, and a cancellation control 1085. In this embodiment, the first prompt message may include the prompt "fix display area, click to resume …" on prompt control 107.

Each of options 1081-1083 may include a selected state and an unselected state. In response to user actions acting on these options, the folding screen device may toggle the options between the selected state and the unselected state. At most one of options 1081-1083 may be in the selected state.

Option 1081 may prompt "this time only" for the function of automatically switching display areas to be opened on the two-dimensional code payment interface in the present WeChat application. And when the two-dimension code payment interface of the WeChat application is switched next time, the function of automatically switching the display area is still closed.

Option 1082 may prompt "all are at this interface later" for the two-dimensional code payment interface in the WeChat application to start the function of automatically switching the display area. That is, when the option 1082 is in the selected state, it indicates that the function of automatically switching the display area is started by the folding screen device as long as the two-dimensional code payment interface in the wechat application is switched.

Option 1083 may prompt "all are in two-dimensional code interface later" for starting the function of automatically switching display areas in all two-dimensional code interfaces. That is, when the option 1082 is in the selected state, it indicates that the function of automatically switching the display area is started by the folding screen device as long as the two-dimensional code interface (a two-dimensional code payment interface in the wechat application, a two-dimensional code interface corresponding to the wechat personal card, and the like) is switched later.

A cancel control 1085 for closing the selection box 108.

And the determination control 1084 is configured to open a function of automatically switching the display area according to the option in the selected state.

For example, option 1081 is in a selected state. In response to the user operation acting on the determination control 1084, the two-dimensional code payment interface of the folding screen device in the WeChat application starts a function of automatically switching the display area. After the function of automatically switching the display areas is started, the folding screen device can detect the posture of the folding screen device, and select one screen from the first display area and the second display area to display the two-dimensional code interface 10 according to the posture of the folding screen device.

In response to a user action on decision control 1084, the fold screen device displays prompt control 109 on two-dimensional code interface 10, as shown in fig. 5 c. Prompt 109 may prompt "click on fixed display area". In response to a user operation applied to the prompt control 109, the folding screen device turns off the function of automatically switching the display area, and displays the prompt control 107 shown in fig. 5a on the two-dimensional code interface 10.

In some embodiments of the present application, after the two-dimensional code interface is displayed on both the first display area and the second display area by the folding screen device, the two-dimensional code interface 10 may be restored to be displayed only on the first display area by closing the state displayed on both the first display area and the second display area in response to a user operation. After the two-dimensional code interface 10 is displayed only on the first display area, the folding screen device can also detect the posture of the folding screen device, and select one display area from the first display area and the second display area to display the two-dimensional code interface 10. Specifically, referring to fig. 6a to 6b, fig. 6a to 6b are schematic diagrams of some user interfaces provided in the embodiments of the present application.

As shown in fig. 6a, the two-dimensional code interface 10 may further include a prompt control 1010 for prompting that "both the primary and secondary screens are displayed, and the user clicks off …". The primary and secondary screens may be a first display area and a second display area. In response to a user operation acting on the prompt control 1010, the folding screen device may close the state in which the two-dimensional code interface 10 is displayed in both display areas, and resume displaying the two-dimensional code interface 10 only on the first display area. Since the two-dimensional code interface 10 is displayed on the first display area by the folding screen device in response to the user operation applied to the receipt and payment option 2053d in the drawing shown in fig. 4a, the two-dimensional code interface 10 is restored to the display on the first display area when the restoration is displayed on only one screen.

When the folding screen device exits from displaying the two-dimensional code interface 10, the folding screen device may also close the state displayed on both the first display area and the second display area, and restore the state in which the interface is displayed only on the first display area. As shown in fig. 6a and 6b, in response to a user operation acting on the return control 106, the fold screen device may display the user interface 20 and close the state displayed on both the first display area and the second display area, displaying the user interface 20 only on the first display area and closing off the second display area from display.

In some embodiments, the pressure sensor 180A may be disposed on the display screen 194. The pressure sensor 180A can be of a wide variety, such as a resistive pressure sensor, an inductive pressure sensor, a capacitive pressure sensor, and the like. The capacitive pressure sensor may be a sensor comprising at least two parallel plates having an electrically conductive material. When a force acts on the pressure sensor 180A, the capacitance between the electrodes changes. The electronic device 100 determines the strength of the pressure from the change in capacitance. When a touch operation is applied to the display screen 194, the electronic apparatus 100 detects the intensity of the touch operation according to the pressure sensor 180A. The electronic apparatus 100 may also calculate the touched position from the detection signal of the pressure sensor 180A. In some embodiments, the touch operations that are applied to the same touch position but different touch operation intensities may correspond to different operation instructions. For example: and when the touch operation with the touch operation intensity smaller than the first pressure threshold value acts on the short message application icon, executing an instruction for viewing the short message. And when the touch operation with the touch operation intensity larger than or equal to the first pressure threshold value acts on the short message application icon, executing an instruction of newly building the short message.

In the embodiment of the present application, the electronic apparatus 100 may also calculate the touched position according to the detection signal of the pressure sensor 180A. When the display screen 194 is a foldable display screen, the electronic device 100 may detect whether the touched position is in the first display area or the second display area of the display screen. The electronic device 10 may determine the pose of the electronic device based on the display area where the continuously touched position is located. The display area facing away from the face is continuously touched due to the holding habit. The folding screen device may determine the display area that is continuously touched as a display area facing away from the face, thereby determining a display area facing the face from the first display area and the second display area.

The gyro sensor 180B may be used to determine the motion attitude of the electronic device 100. In some embodiments, the angular velocity of electronic device 100 about three axes (i.e., the x, y, and z axes) may be determined by gyroscope sensor 180B. The gyro sensor 180B may be used for photographing anti-shake. For example, when the shutter is pressed, the gyro sensor 180B detects a shake angle of the electronic device 100, calculates a distance to be compensated for by the lens module according to the shake angle, and allows the lens to counteract the shake of the electronic device 100 through a reverse movement, thereby achieving anti-shake. The gyroscope sensor 180B may also be used for navigation, somatosensory gaming scenes.

In this embodiment, the electronic device 100 may further detect an included angle of the bending of the foldable display screen, that is, an opening angle, through the acceleration sensor 180E and/or the gyroscope sensor 180B. The electronic device 100 can also determine the form of the foldable display screen, such as the flat form, the folded form, or the unfolded form, according to the included angle of the bending.

Specifically, the body portion of the foldable display screen where the first display area is located may include at least one gyro sensor 180B. The body portion where the second display area is located may also include at least one gyro sensor 180B. Through the two groups of sensors, the electronic equipment can determine triaxial data (in m/s2, the sampling frequency is 100Hz) of the acceleration sensor and triaxial data (in rad/s, the sampling frequency is 100Hz) of the gyroscope sensor after zero offset correction. Then, the electronic device may extract the acceleration sensor value (unit is m/s2, sampling frequency is 100Hz) and the system time corresponding to the data from the acceleration sensor triaxial data through a filtering algorithm, and calculate through a further fusion algorithm using these parameters, to obtain the angle change of the orientation of each display region. And then the electronic equipment can determine the included angle of the two display areas, namely the opening angle of the two display areas of the foldable display screen.

In the embodiment of the present application, the principle that the gyro sensor a measures the orientation (i.e., the directional vector of the orientation) of the first display area, the gyro sensor B measures the orientation (i.e., the directional vector of the orientation) of the second display area, and the principle that the electronic device 100 calculates the opening angle α of the first display area and the second display area according to the orientation of the first display area and the orientation of the second display area are explained.

Wherein the coordinate system of the gyro sensor may be a geographical coordinate system. As shown in fig. 12b, the origin O of the geographic coordinate system may be located at the point where the vehicle (i.e., the device containing the gyro sensor, such as the electronic device 100) is located, with the X-axis pointing east (E) along the local latitudes, the Y-axis pointing north (N) along the local meridian, and the Z-axis pointing up along the local geographic vertical, and forming a right-hand orthogonal coordinate system with the X-axis and the Y-axis. The plane formed by the X axis and the Y axis is the local horizontal plane, and the plane formed by the Y axis and the Z axis is the local meridian plane. Thus, it can be understood that the coordinate system of the gyro sensor is: the gyroscope sensor is used as an origin O, the east direction along the local latitude line is used as an X axis, the north direction along the local meridian line is used as a Y axis, and the upward direction along the local geographical vertical line (namely the direction of the geographical vertical line) is used as a Z axis.

The electronic device 100 may measure the direction vector of the orientation in the coordinate system of the gyro sensor corresponding to each display region by using the gyro sensor provided on the body corresponding to each display region.

The system library can comprise a display module and can also comprise other functional modules. For example: surface managers (surface managers), Media Libraries (Media Libraries), three-dimensional graphics processing Libraries (e.g., OpenGLES), 2D graphics engines (e.g., SGL), and the like.

The display module can be used for receiving the notification from the information processing module in the application framework layer. In a scene of closing the function of the automatic switching display area, the display module may close the function of the automatic switching display area according to the current form of the display screen and the state that the function of the automatic switching display area is opened. Specifically, steps S106 to S109 in the example described with reference to fig. 15 can be used.

In a scenario where the first display region and the second display region simultaneously display a particular user interface, the display module may notify the display driver, initialize a currently undisplayed screen (e.g., the second display region) and display on both the first display region and the second display region. The step S208 in the example described with reference to fig. 16 may be specifically mentioned.

In an embodiment of the application, the system library may further include an angle calculation module for determining a form of the display screen. The angle calculation module can acquire angle data from the sensor drive of the inner core layer, calculate the opening angle of the display screen, and determine the form of the display screen according to the opening angle, such as a flat state, a folded state or an unfolded state. The display module may query the angle calculation module for the form of the display screen, and when the form of the display screen is the folding form, the display module may close the function of automatically switching the display area or notify the display driver to display a specific user interface in both the first display area and the second display area, which may be specifically described in step S107 to step S109 in the example described with reference to fig. 15.

In another possible implementation, an application (e.g., a wechat application) may obtain a current form of the display screen from the angle calculation module, and only when the display screen is in a folded form, the wechat application sends a notification to the information processing module according to the switched two-dimensional code interface, which may specifically refer to steps S204 to S206 in the example described with reference to fig. 16.

When the acceleration sensor 180E and the gyro sensor 180E detect angle data, a corresponding hardware interrupt is issued to the kernel layer. And the sensor drive of the inner core layer sends the angle data to an angle calculation module in the system library.

It should be noted that the functional architecture of the electronic device shown in fig. 14 is only one implementation manner of the embodiment of the present application, and in practical applications, the electronic device may further include more or fewer software modules, which is not limited herein.

The user interface displayed by the display module can be implemented as described with reference to fig. 1a to 1b and fig. 3a to 10 b. The display module may be embodied as the display screen 194 in fig. 11.

Based on the software architecture diagram shown in fig. 14, a display method in the folding screen device provided in the embodiment of the present application is described below by way of a specific example. Fig. 15 is a schematic flowchart of a display method according to an embodiment of the present application. In the display method, when the folding screen device is switched to a specific user interface (such as a two-dimensional code interface), the folding screen device closes the function of automatically switching the display area. When the folding screen device exits the specific user interface, the folding screen device can resume the function of starting the automatic switching display area.

Fig. 4a to 4c and fig. 5a to 5c are referenced for an application interface related to the display method. As shown in fig. 15, the display method includes steps S101 to S115.

S101, an angle calculation module receives angle data from a sensor drive.

Wherein the sensor drive may drive a sensor (e.g., gyroscope sensor 180E) to measure angular data. Not limited to the sensors shown in the examples, the sensor driven sensor may also comprise other sensors that can measure the attitude of the folding screen device, such as hall sensors, etc., acceleration sensors, etc. The hall sensor can detect the opening and closing of the body where the two display areas are located, so as to determine that the display screen is in the folded state or the unfolded state (including the unfolded state and the unfolded state), which is described in the example specifically with reference to fig. 11.

S102, the form of the display screen is determined by an angle calculation module.

In the embodiments of the present application, the configuration of the display screen may include a flat configuration, a folded configuration, and an unfolded configuration, and reference may be made to the concept description section above. In the embodiment of the present application, the display method provided in the embodiment of the present application is executed when the display screen is in the folded state or the unfolded state. The display method provided by the embodiments of the present application may not be performed when the display screen is in the flattened state.

In the embodiment of the application, the angle calculation module and the sensor drive the sustainable detection data so as to acquire the form of the display screen in real time. And S103, displaying the user interface 20 in the first display area by the display driving display screen.

And S104, switching the WeChat application to the two-dimensional code interface, and executing the step S105.

Wherein the WeChat application can include a plurality of interfaces (e.g., a message list interface, a two-dimensional code interface, a chat window interface, a circle of friends interface, etc.). The WeChat application may also contain control logic for various interface switches. The control logic for interface switching includes the correspondence between the control and the interface content, which includes, for example, the correspondence between the payment and receipt option 2053d in fig. 4a and the two-dimensional code interface 10. The principle of switching the two-dimensional code interface by the wechat application is described below with reference to the scenarios shown in fig. 4a to 4 b.

When the touch sensor 180K receives a touch operation at the location of option 2053 in FIG. 4a, a corresponding hardware interrupt is issued to the kernel layer. The kernel layer processes the touch operation into an original input event (including touch coordinates, a time stamp of the touch operation, and other information). The raw input events are stored at the kernel layer. And the application program framework layer acquires the original input event from the kernel layer and identifies the control corresponding to the input event. The control corresponding to the touch operation is a payment and receipt option 2053d in the user interface 20 of the wechat application, and the application framework layer notifies the name of the payment and receipt option 2053d to the wechat application. The wechat application finds the interface content corresponding to the payment and receipt option 2053d according to the control logic of interface switching, namely the interface is the two-dimensional code interface, and then the wechat application switches to the two-dimensional code interface. In this embodiment of the application, the two-dimensional code interface is, for example, the wechat payment code 10 shown in fig. 4a and 4b, may also be a two-dimensional code interface including personal information in wechat application, may also be an interface including certain account information, certain webpage information, certain commodity information, and may also be a bus code, and the like, which is not limited in this embodiment of the application. For example, the WeChat application may switch to the two-dimensional code interface 10 in response to a user action on the collect and pay option 2053d shown in FIG. 4 a.

In addition, the folding screen device is not limited to the two-dimensional code interface, and can also close the function of automatically switching the display area when other specific user interfaces are displayed. That is, the aforementioned specific user interface is not limited to the two-dimensional code interface. Other user interfaces such as a gallery user interface, a video user interface, etc. The user interface of the gallery may refer to fig. 8a and 8b, and the user interface of the video may include, for example, the interface shown in fig. 9.

S105, the WeChat application sends a first notice to the information processing module, and the first notice indicates that the two-dimensional code interface is switched.

In the embodiment of the present application, through the setting process of the example shown in fig. 7a and 7b in the folding screen device, the information processing module can know on which user interfaces the function of automatically switching the display area needs to be turned off. For example, as shown in fig. 7b, the options corresponding to the user interfaces of the two-dimensional code interface (WeChat Payment code, WeChat personal card, Payment code … …) and the gallery are selected. In response to the user operation applied to the determination control 403, the information processing module may know that the function of automatically switching the display area needs to be turned off when the user interface of the two-dimensional code interface or the gallery is displayed. So that step S106 is performed when the information processing module receives the first notification from the application.

S106, the information processing module sends a second notification to the display module, and the second notification indicates that the display area needs to be fixedly switched.

In the embodiment of the application, when the folding screen device is in the folding state, the display area is not switched fixedly, that is, the function of automatically switching the display area is turned off. Therefore, before performing step S109, the information processing module needs to perform step S107 to determine the shape of the display screen of the current folding screen device.

S107, the display module acquires the current display screen from the angle calculation module as a folding state, and executes the step S108.

In the embodiment of the present application, when the display module obtains that the current display screen is in the flat state from the angle calculation module, the process is ended, and steps S108 to S109 are not executed.

And S108, the display module detects that the function of automatically switching the display area is opened.

In the embodiment of the present application, when the function of automatically switching the display area is turned off, the display may be performed only on the area currently used for displaying (e.g., the first display area) without performing step S109.

In the embodiment of the present application, whether the function of automatically switching the display area is on or not may be indicated by an identifier, for example, identifier 1 indicates that the function of automatically switching the display area is on, and identifier 0 indicates that the function of automatically switching the display area is off. The function of closing the auto-switching display area is to set the flag to 0, and the function of opening the auto-switching display area is to set the flag to 1.

The display module may store the identification. The display module may further record a display area of the currently displayed content, for example, record the display area of the currently displayed content as the first display area. When the flag is 0, the display module notifies the display driver to display the content only in the current display area (e.g., the first display area). When the identifier is 1, the display module obtains the current posture of the folding screen device from the modules in the system library, and determines a display area (a first display area or a second display area) for displaying the content according to the current posture of the folding screen device. Modules in the system library may determine the current pose of the folding screen device based on data detected by a sensor (e.g., a gyroscope sensor).

And S109, the display module closes the function of automatically switching the display area.

In this embodiment, the display module only turns off the function of the auto-switching display area during displaying the specific user interface, for example, the two-dimensional code interface. When the two-dimensional code interface is exited, for example, as shown in fig. 6a and 6b, the function of opening the automatic switching display area may be resumed when the folding screen device displays the user interface 20 in response to the user operation applied to the return control 106, that is, steps S112 to S115.

S110, the display module sends a third notification to the display driver, where the third notification indicates that the display is performed in the current area for display (e.g., the first display area).

In this embodiment of the application, the area currently used for displaying refers to a display area used for displaying in the folding screen device when the two-dimensional code interface is switched to, and may be the first display area or the second display area.

And S111, displaying a two-dimensional code interface on the first display area by the display driving display screen.

And during the period that the display screen displays the two-dimensional code interface, the display driver determines that the display screen displays the two-dimensional code interface on the first display area. No matter what posture the folding screen device is in, and no matter the state that the first display area and the second display area are touched, the folding screen device does not switch the display area for displaying the two-dimensional code interface.

And S112, quitting the two-dimensional code interface by the WeChat application.

For example, the example shown in FIG. 4b, the WeChat application may exit the two-dimensional code interface in response to a user operation acting on the return control 106. The principle of the wechat application exiting the two-dimensional code interface is described below with reference to the scenarios shown in fig. 6a to 6 b.

When the touch sensor 180K receives a touch operation that acts on the return control 106 in fig. 6a, a corresponding hardware interrupt is issued to the kernel layer. The kernel layer processes the touch operation into an original input event (including touch coordinates, a time stamp of the touch operation, and other information). The raw input events are stored at the kernel layer. And the application program framework layer acquires the original input event from the kernel layer and identifies the control corresponding to the input event. The control corresponding to the touch operation is a return control 106 in the two-dimensional code interface 10, and the application framework layer notifies the WeChat application of the name of the return control 106. The wechat application finds the interface content corresponding to the return control 106 according to the control logic of the interface switching, namely the interface content is the user interface 20, and the wechat application switches to the user interface 20, namely exits from the two-dimensional code interface 10.

S113, the WeChat application sends a fourth notification to the information processing module to indicate that the two-dimensional code interface is exited.

S114, the information processing module sends a fifth notification to the display module to indicate that the function of automatically switching the display area needs to be started.

And S115, the display module starts the function of automatically switching the display area.

In the embodiment of the application, after the function of automatically switching the display area is started, the sensor driver can drive the sensor to detect the posture of the device in real time, the display module can determine the display area for displaying the content according to the posture of the folding screen device and send a notification to the display driver, so that the display driver drives the first display area or the second display area to display the user interface.

In other embodiments of the present application, the wechat application may obtain the current form of the display screen from the angle calculation module, and when the display screen is in the folded form or the unfolded form, the wechat application performs step S104 according to the switched two-dimensional code interface. When the display screen is in the flat state, the step S104 is not executed. The display module does not need to detect the form of the display screen, i.e. does not need to perform step S107.
