Description

Technical Field

[0001] The present application relates to the field of electronic technology, and in particular to a folding screen control method and electronic device. Background Art

[0002] At present, electronic devices such as mobile phones and tablet computers have been widely used in people's daily life and work. With the advancement of screen technology, the display screens of electronic devices are gradually developing towards large screens to provide users with richer information and better visual experience.

[0003] When the display screen of an electronic device is too large, it will affect its portability. Therefore, electronic devices with foldable screens have emerged. Foldable screens can present different physical forms based on user operations, such as unfolded form and folded form. In the unfolded form, the foldable screen can be used as a large screen; in the folded form, it can be convenient for users to carry.

[0004] While the folding screen brings a large-screen experience to users, its own folding structure also puts forward requirements for user operation. Therefore, how to improve the user's operating experience is a technical problem to be solved in this field. Summary of the invention

[0005] In view of this, the present application provides a folding screen control method and an electronic device for improving the user's operating experience.

[0006] In order to achieve the above-mentioned purpose, in a first aspect, an embodiment of the present application provides a folding screen control method, which is applied to an electronic device with a folding screen, and the method includes:

[0007] receiving a folding operation acting on the folding screen, the folding screen comprising: a first screen, a second screen, a third screen, a first folding axis and a second folding axis, the first folding axis being located between the first screen and the second screen, and being used to fold or unfold the first screen relative to the second screen; the second folding axis being located between the second screen and the third screen, and being used to fold or unfold the third screen relative to the second screen; in a correct folding order, folding the third screen first and then folding the first screen;

[0008] In response to the folding operation, in response to an abnormal folding order of the folding screen, a first prompt message is issued.

[0009] The folding screen control method provided in the embodiment of the present application is that the electronic device can respond to the folding operation of the user on the folding screen after receiving the folding operation of the user. When the folding order of the folding screen is abnormal, the electronic device can respond to the abnormal situation and issue a prompt message. This can help the user to fold in the correct folding order, improve the user's operating experience, and reduce the impact of user folding errors on the service life of the electronic device.

[0010] In a possible implementation manner of the first aspect, in response to an abnormal folding order of the folding screen and when a first target condition is met, issuing the first prompt information;

[0011] The first target condition includes: the duration of the abnormal folding sequence reaches a first duration, or a touch operation acting on a first target area is detected, or the abnormal folding sequence of the folding screen is detected based on multiple detection methods.

[0012] Through the above implementation, false triggering can be reduced and the accuracy of the control result can be improved.

[0013] In a possible implementation of the first aspect, the folding order of the folding screen is abnormal, including: a difference between a first angle and a second angle is less than a preset threshold, the first angle is the angle between the first screen and the second screen, and the second angle is the angle between the second screen and the third screen.

[0014] In the above implementation, whether the folding order of the folding screen is abnormal is judged based on the angle relationship between adjacent screens in the folding screen, so that the abnormal folding order of the folding screen can be determined relatively early, thereby improving the timeliness of the abnormal folding order detection.

[0015] In a possible implementation of the first aspect, the folding order of the folding screen is abnormal, including: the first angle is smaller than a preset angle, and the difference between the first angle and the second angle is smaller than the preset threshold.

[0016] In the above implementation, when it is determined that the folding order of the folding screen is abnormal, by limiting the first angle to be less than a preset angle, conflicts with other folding operations can be reduced and the accuracy of the control result can be improved.

[0017] In a possible implementation manner of the first aspect, one of the first screen and the second screen is correspondingly provided with a first magnet, the other is correspondingly provided with a Hall sensor, and the third screen is correspondingly provided with a second magnet; in a folded state, the third screen is located between the first screen and the second screen, the projections of the first magnet, the second magnet, and the Hall sensor on the second screen overlap, the first magnetic pole of the first magnet and the second magnetic pole of the second magnet face the Hall sensor, and the polarity of the first magnetic pole is opposite to the polarity of the second magnetic pole;

[0018] The electronic device determines that the folding sequence of the folding screen is abnormal when the Hall sensor senses the approach of the first magnetic pole but does not sense the second magnetic pole or the magnetic field strength of the sensed second magnetic pole is less than the first strength.

[0019] In the above implementation, based on the magnetic induction relationship between adjacent screens in the folding screen, it is determined whether the folding order of the folding screen is abnormal, and the required magnetic induction device has a low cost, thereby reducing the hardware cost.

[0020] In a possible implementation manner of the first aspect, one of the first screen and the second screen is correspondingly provided with a magnet, and the other is correspondingly provided with a Hall sensor; in a folded state, the third screen is located between the first screen and the second screen, and projections of the magnet and the Hall sensor on the second screen overlap;

[0021] When the Hall sensor senses the magnet and the sensed magnetic field strength is greater than the target strength, the electronic device determines that the folding sequence of the folding screen is abnormal.

[0022] In the above implementation, based on the magnetic induction relationship between adjacent screens in the folding screen, it is determined whether the folding order of the folding screen is abnormal, and the required magnetic induction device has a low cost, thereby reducing the hardware cost.

[0023] In a possible implementation manner of the first aspect, the first prompt information includes: prompt information for prompting that the folding sequence is incorrect, and / or prompt information for prompting a correct folding sequence.

[0024] Through the above implementation, it is convenient for the user to know the situation where the folding sequence is wrong, and it is also convenient for the user to know the correct folding sequence, thereby improving the user's usage experience.

[0025] In a possible implementation of the first aspect, the first prompt information includes at least one of the following: interface display information, vibration information, sound information, and light information. This can improve the flexibility and richness of information prompts.

[0026] In a possible implementation of the first aspect, in a folded state, a thickness of the first folding axis in a first direction is greater than a thickness of the second folding axis in the first direction, and the first direction is perpendicular to a display plane of the second screen.

[0027] In a possible implementation of the first aspect, the method further includes:

[0028] receiving a target operation acting on the folding screen, the target operation being used to change the angle between a first target screen and a second target screen, the first target screen and the second target screen being two adjacent screens of the folding screen, the first target screen and the second target screen being capable of being folded in a first direction around a target folding axis, and the target folding axis being a folding axis between the first target screen and the second target screen;

[0029] In response to the target operation, in response to the first target screen and the second target screen being folded in a second direction, a second prompt message is issued, and the second direction is opposite to the first direction.

[0030] In the above embodiment, the electronic device can respond to the target operation (used to change the angle between adjacent screens of the folding screen) after receiving the user's target operation on the folding screen. When the folding screen is folded, it responds to the situation and issues a prompt message. This can help the user fold it in the correct folding direction, improve the user's operating experience, and reduce the impact of user folding errors on the service life of the electronic device.

[0031] In a possible implementation manner of the first aspect, in response to the first target screen and the second target screen being folded in a second direction and when a second target condition is met, the second prompt information is issued;

[0032] The second target condition includes: the duration of the folding of the first target screen and the second target screen in the second direction reaches a second duration, or a touch operation acting on the second target area is detected, or, based on multiple detection methods, it is detected that the first target screen and the second target screen are folded in the second direction.

[0033] Through the above implementation, false triggering can be reduced and the accuracy of the control result can be improved.

[0034] In a possible implementation of the first aspect, the first target screen and the second target screen are folded in a second direction, including: an angle between the first target screen and the second target screen is greater than a second threshold, and the second threshold is greater than 180°.

[0035] In the above embodiment, whether the folding screen is folded back is determined based on the angle between adjacent screens in the folding screen, so that abnormal folding order of the folding screen can be determined relatively conveniently and quickly, and the existing sensor for detecting the screen angle in the folding screen can be utilized to reduce hardware costs.

[0036] In a possible implementation of the first aspect, a pressure sensor is disposed between the first target screen and the second target screen, and the electronic device determines that the first target screen and the second target screen are folded in a second direction when the pressure detected by the pressure sensor is greater than a pressure threshold.

[0037] In the above implementation, by judging whether the folding screen is folded back based on the pressure, it is possible to relatively quickly determine that the folding sequence of the folding screen is abnormal, thereby improving the timeliness of the folding detection.

[0083] The embodiments of the present application are described below in conjunction with the drawings in the embodiments of the present application. The terms used in the implementation method section of the embodiments of the present application are only used to explain the specific embodiments of the present application, and are not intended to limit the present application. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

[0084] First, the folding screen involved in the embodiment of the present application is described. In the embodiment of the present application, "electronic device with folding screen" can also be referred to as "foldable electronic device", "folding screen device" or "electronic device", etc., specifically referring to an electronic device with a foldable display screen.

[0085] Among them, the folding screen can be folded to form multiple screens. Figure 1 As shown in (a) of FIG. 1 , after the folding screen of the electronic device is folded along the folding axis, a folding screen can be formed as shown in FIG. Figure 1 The A screen 11 and the B screen 12 shown in (b) in FIG. Figure 2 After the folding screen shown in (a) is folded along the folding axis, it can form a Figure 2 The A screen 21, the B screen 22 and the C screen 23 shown in (b) .

[0086] The physical form of the foldable screen can include an unfolded form, a folded form, and a semi-folded form (also referred to as a semi-unfolded form). Figure 1 (a) and Figure 2 (a) in the figure is a schematic diagram of the folding screen in the unfolded state. Figure 1 (b) Figure 2 (b) is a schematic diagram of the folding screen in a semi-folded state. Figure 1 (c) and Figure 2 (c) is a schematic diagram of the folding screen when it is in a folded state.

[0087] The value range of the angle between two adjacent screens in the folding screen can be [0°, 180°], where in the unfolded state, the angle between two adjacent screens in the folding screen is 180°, for example, Figure 1As shown in (a), the angle α between the A screen 11 and the B screen 12 is 180°; for another example, Figure 2 As shown in (a), the angle α1 between the A screen 21 and the B screen 22 is 180°, and the angle α2 between the B screen 22 and the C screen 23 is 180°.

[0088] In the semi-folded state, the angle between two adjacent screens in the folding screen ranges from (0° to 180°). For example, Figure 1 As shown in (b), the angle α∈(0°, 180°) between the A screen 11 and the B screen 12; Figure 2 As shown in (b), the angle α1∈(0°, 180°) between the A screen 21 and the B screen 22, and the angle α2∈(0°, 180°) between the B screen 22 and the C screen 23.

[0089] In the folded state, the angle between two adjacent screens in the folding screen is 0°, for example, Figure 1 As shown in (c), the angle α between the A screen 11 and the B screen 12 is 0°. For another example, Figure 2 As shown in (c), the angle α1 between the A screen 21 and the B screen 22, and the angle α2 between the B screen 22 and the C screen 23 are both 0°.

[0090] It can be understood that, in the unfolded form, the angle between two adjacent screens of the folding screen may deviate slightly from 180°, for example, the angle between two adjacent screens in the unfolded form is 175° or 185°, etc.; similarly, in the folded form, the angle between two adjacent screens of the folding screen may deviate slightly from 0°, for example, the angle between two adjacent screens in the folded form is 5°, etc.

[0091] In the embodiments of the present application, there are two folding methods for adjacent screens in the folding screen. One is folding inward (referred to as inward folding). In this folding method, after the two screens are folded, the light-emitting surfaces of the two screens are opposite to each other; the other is folding outward (referred to as outward folding). In this folding method, after the two screens are folded, the light-emitting surfaces of the two screens are opposite to each other.

[0092] For example, Figure 1 The folding method of the folding screen shown in the figure is outward folding, and the A screen 11 and the B screen 12 can be folded outward around the folding axis to form Figure 1 The shape shown in (b) in FIG. 1 ; the A screen 11 and the B screen 12 are further folded to form Figure 1 The form shown in (c) in .

[0093] Figure 2 In the folding screen shown in FIG, the folding method of the A screen 21 and the B screen 22, and the folding method of the B screen 22 and the C screen 23 are all inward folding. Figure 2After the A screen 21 and the B screen 22 shown in (a) are folded inwardly around the folding axis 1, and the B screen 22 and the C screen 23 are folded inwardly around the folding axis 2, the following can be formed: Figure 2 The A screen 21, the B screen 22 and the C screen 23 are further folded to form Figure 2 The form shown in (c) in .

[0094] Understandably, Figure 1 The folding method of the folding screen shown in can also be inward folding. Figure 2 The folding screen shown in (a) may also be: the folding mode of the A screen 21 and the B screen 22, and the folding mode of the B screen 22 and the C screen 23 are all outward folding, or the folding mode of the A screen 21 and the B screen 22 is outward folding, and the folding mode of the B screen 22 and the C screen 23 is inward folding, or the folding mode of the A screen 21 and the B screen 22 is inward folding, and the folding mode of the B screen 22 and the C screen 23 is outward folding. The embodiment of the present application does not specifically limit the folding mode of the folding screen.

[0095] Figure 1 and Figure 2 In the embodiment, the folding screen is folded longitudinally into multiple screens distributed left and right. In other embodiments, the folding screen of the electronic device can also be folded horizontally into multiple screens distributed up and down.

[0096] It can be understood that the number of screens included in the folding screen is divided and named based on the folding axis around which the folding screen is folded. The multiple screens described here do not represent the actual panel structure of the folding screen.

[0097] In some embodiments, the folding screen may be a flexible folding screen. The folding axis of the flexible folding screen is made of a flexible material, and the other parts of the flexible folding screen may be made of a rigid material or a flexible material. The flexible folding screen may be folded along the folding axis to form multiple screens; the multiple screens formed after the flexible folding screen is folded are a complete screen of an integrated structure, but are folded to form at least two parts, and each part is correspondingly called a screen.

[0098] In some embodiments, the folding screen may also be a multi-screen folding screen. The multi-screen folding screen may include multiple independent screens, which may be connected in sequence through folding axes, and each screen may rotate around the folding axis connected thereto to achieve folding of the multi-screen folding screen.

[0099] For some multi-fold folding screens (i.e., folding screens including at least three screens), when folding from an unfolded state or a semi-folded state to a folded state, the user is required to fold in a certain folding order. Figure 2 The folding screen shown in , which corresponds to two folding axes, see Figure 2In (c), the direction perpendicular to the display plane of screen B in the folded state is defined as the thickness direction of the folding axis. The thicknesses of the two folding axes of the folding screen are different, among which the thickness of folding axis 2 is smaller than the thickness of folding axis 1. When folding, screen C needs to be folded first, and then screen A. If screen A is folded first, and then screen C, the electronic device cannot be closed. Moreover, there is no support of screen C between screen A and screen B. Folding axis 1 supports screen A and screen C alone, which will be subjected to excessive pressure, thereby affecting the service life of folding axis 1. Adding screen A between screen B and screen C will also cause folding axis 2 to be subjected to excessive tension, thereby affecting the service life of folding axis 2. In addition, if the folding screen is not closed smoothly, the display screen will also be subjected to uneven force, thereby affecting the service life of the display screen.

[0100] It is understandable that outward-folding folding screen devices and other folding screen devices that include both inward-folding and outward-folding also require users to fold them in a certain folding order due to size limitations or other reasons. For the sake of convenience, the embodiments of this application mainly take the inward-folding folding screen device as an example for exemplary description.

[0101] In order to help users fold electronic devices in the correct folding order, such as Figure 3 As shown, a possible implementation method is to set a brake mechanism 24 in the electronic device. The brake mechanism 24 is a linkage mechanism. When the folding axis 2 is opened (i.e., the B screen and the C screen are unfolded), the motion structure on the folding axis 2 drives the brake mechanism 24, and the brake mechanism 24 locks the folding axis 1, so that the folding axis 1 cannot be closed, that is, the A screen and the B screen are prevented from folding; when the folding axis 2 is closed (i.e., the B screen and the C screen are folded), the motion structure on the folding axis 2 drives the brake mechanism 24, and the brake mechanism 24 releases the lock on the folding axis 1, so that the folding axis 1 can be closed, that is, the A screen and the B screen are allowed to fold. In this way, the user is restricted from folding the A screen first and then the C screen, and the user is helped to fold the electronic device in the correct folding order of folding the C screen first and then the A screen.

[0102] However, in the above implementation, the braking mechanism separates the internal space of screen B, which is not conducive to the internal structure design. For example, a large battery could be placed originally, but after adopting the braking mechanism, the braking mechanism needs to be avoided and the battery needs to be split into two smaller batteries, which will affect the battery capacity; in addition, when the user finds that the folding cannot be done, he or she may not immediately think that the folding order is wrong, but instead think that the folding force is not enough and further fold it with force, thereby damaging the braking mechanism and affecting the service life of the electronic device.

[0103] To this end, an embodiment of the present application provides a folding screen control method, which can detect the folding order of the folding screen when receiving the user's folding operation on the folding screen, and issue a prompt message when it is detected that the folding order of the folding screen is abnormal, so as to help the user fold it in the correct folding order, improve the user's operating experience, reduce the impact of user folding errors on the service life of the electronic device, and reduce the impact of hardware modification on the internal structure design of the folding screen.

[0104] Figure 4 A schematic diagram of a folding screen control method provided in an embodiment of the present application is shown in FIG. Figure 4 As shown, the method may include the following steps:

[0105] S110: receiving a folding operation on the folding screen.

[0106] The folding screen includes a first screen, a second screen and a third screen that are adjacent to each other in sequence. In a correct folding sequence, the folding sequence of the third screen precedes the folding sequence of the first screen. Figure 2 In the folding screen shown in FIG. 1 , the first screen is the A screen 21, the second screen is the B screen 22, and the third screen is the C screen 23. Figure 2 The folding screen shown is used as an example for exemplary description.

[0107] It can be understood that the folding screen can include more screens, and the first screen, second screen and third screen mentioned above can be any three adjacent screens in the folding screen with a folding order. For the sake of convenience of explanation, the embodiment of the present application mainly takes the folding screen including three screens as an example for illustrative explanation.

[0108] For example, Figure 2 As shown in (a) in the figure, the folding screen is initially in an unfolded state. When the user wants to fold the folding screen into a folded state, the folding screen can be folded, for example, screen A and screen C can be folded inward in sequence; the electronic device can determine whether the folding order corresponding to the folding operation is correct or abnormal based on the user's folding operation of the folding screen.

[0109] Among them, the electronic device can detect the folding operation performed by the user on the folding screen through one or more of a gravity sensor, an acceleration sensor, and a gyroscope; the electronic device can also detect the folding operation performed by the user on the folding screen through an angle sensor set at the bending part of the folding screen. For example, when the angle between adjacent screens detected by the angle sensor becomes smaller, it can be determined that the user has performed a folding operation on the folding screen. In some embodiments, the electronic device can also detect the folding operation performed by the user on the folding screen through a physical switch set at the bending part of the folding screen; for example, when the user performs a folding operation on the folding screen, the physical switch set on the electronic device will be triggered to open, and the electronic device can detect the folding operation performed by the user on the folding screen based on the opening of the physical switch.

[0110] It is understandable that the manner in which the electronic device detects a folding operation is not limited to the above examples, and the embodiments of the present application do not specifically limit this.

[0111] S120. In response to the folding operation, when it is detected that the folding order of the folding screen is abnormal, a first prompt message is issued.

[0112] After the electronic device receives the user's folding operation on the folding screen, it can respond to the folding operation and detect whether the folding order of the folding screen (that is, the folding order corresponding to the folding operation) is abnormal.

[0113] The following is an illustrative description of two implementation methods for detecting whether the folding order of the folding screen is abnormal.

[0114] The first method is to detect whether the folding order of the folding screen is abnormal based on the angle relationship between adjacent screens in the folding screen.

[0115] The electronic device can determine that the folding order of the folding screen is abnormal when it detects that the difference between the angle between the first screen and the second screen (hereinafter referred to as the first angle) minus the angle between the second screen and the third screen (hereinafter referred to as the second angle) is less than a preset threshold (hereinafter referred to as the first threshold).

[0116] The electronic device may determine the angle between adjacent screens in the following manner:

[0117] In some embodiments, a gyroscope sensor may be provided corresponding to each screen of the folding screen to measure the orientation of the corresponding screen (i.e., the orientation vector). The electronic device may determine the angle between adjacent screens based on the orientation angle change of each screen measured by the gyroscope sensor.

[0118] The coordinate system of the gyroscope sensor is a geographic coordinate system, the origin O of which is located at the carrier (i.e., the device containing the gyroscope sensor), the x-axis points east along the local latitude, the y-axis points north along the local meridian, and the z-axis points upward along the local geographic vertical line, and forms a right-hand rectangular coordinate system with the x-axis and the y-axis. The electronic device uses the gyroscope sensor corresponding to each screen to measure the direction vector of each screen in the coordinate system of the gyroscope sensor where it is set.

[0119] by Figure 1 Taking the folding screen shown in as an example, the folding screen of the electronic device can be folded to form Figure 5 The A screen and the B screen are shown in FIG. A gyroscope sensor a is provided in the housing corresponding to the A screen, and a gyroscope sensor b is provided in the housing corresponding to the B screen. The direction vector (hereinafter referred to as the direction vector) of the orientation of the A screen in the coordinate system of the gyroscope sensor a measured by the electronic device is vector V A , the orientation vector of screen B in the coordinate system of gyro sensor b is vector V B The vector V can be calculated by the following formula (1): A With vector V B The angle θ.

[0120]

[0121] according to Figure 5 It can be seen that the vector V A Perpendicular to screen A, vector V B It is perpendicular to screen B, therefore, the angle between screen A and screen B is α=180°-θ.

[0122] It should be noted that although the positions of the gyro sensors of screen A and screen B do not overlap, that is, the origins of the coordinate systems of the gyro sensors of screen A and screen B do not overlap, the x-axis, y-axis, and z-axis of the two coordinate systems are parallel, so it can be considered that the coordinate systems of the gyro sensors of screen A and screen B are parallel. A and vector V B They are not in the same coordinate system, but because the axes of the two coordinate systems are parallel, the vector V can still be calculated using the above formula (1): A With vector V B The angle θ between them.

[0123] The angle between any two adjacent screens in the folding screen can be calculated by the above method. Correspondingly, for Figure 2 The folding screen with three screens shown in Figure 6 As shown in A 、B screen's orientation vector V B and the orientation vector V of the C screenC The angle α1 between screen A and screen B, and the angle α2 between screen B and screen C can be calculated by the following formula (2).

[0124]

[0125] In some embodiments, one or more other sensors may be used to measure the angle between adjacent screens. For example, a rotation vector sensor (integrated with an accelerometer, a gyroscope, and a magnetometer) may be provided in the housing corresponding to each screen of the folding screen. The electronic device may use the rotation vector sensor to calculate the rotation angle of each screen, wherein the rotation axes of each screen are parallel. Therefore, the rotation axes may be as follows: Figure 7 As shown in the figure, the electronic device determines the rotation angle θ of the A screen according to the data measured by the rotation vector sensor. A , the rotation angle of screen B is θ B , the rotation angle of screen C is θ C The angle α1 between screen A and screen B, and the angle α2 between screen B and screen C can be calculated by the following formula (3).

[0126]

[0127] In other embodiments, an angle sensor may be installed at the folding portion of the folding line of the electronic device (for example, on the folding axis), and the electronic device may measure the angle between adjacent screens by using the angle sensor disposed at the folding portion of the folding screen.

[0128] It is understandable that the method for determining the angle between adjacent screens is not limited to this, and other methods may be used to determine the angle between adjacent screens, and the embodiments of the present application do not specifically limit this.

[0129] When the user folds the folding screen, the angles between adjacent screens of the folding screen will change. For example, Figure 8 As shown in (a) of FIG. 1 , if the user folds the display in the correct order, that is, folds screen C first and then screen A, during the folding process, the angle α1 between screen A and screen B is generally greater than the angle α2 between screen B and screen C; Figure 8 As shown in (b) in FIG. 1 , if the user folds in the wrong folding order, that is, folds screen A first and then screen C, during the folding process, the angle α1 between screen A and screen B is generally smaller than the angle α2 between screen B and screen C.

[0130] Based on this, while the user is folding the folding screen, the electronic device can periodically measure the angles between adjacent screens of the folding screen, and then detect whether the folding order of the folding screen is abnormal based on the size relationship of the angles between adjacent screens.

[0131] For example Fig. 9 As shown in , in each detection cycle, after obtaining the angle α1 between screen A and screen B, and the angle α2 between screen B and screen C, the electronic device can determine whether the value of α1-α2 is greater than or equal to the first threshold Th1. When the value of α1-α2 is greater than or equal to the first threshold Th1, the electronic device can determine that the folding sequence of the folding screen is normal and continue the folding sequence detection process of the next cycle; when the value of α1-α2 is less than the first threshold Th1, the electronic device can determine that the folding sequence of the folding screen is abnormal, and at this time, a prompt message (i.e., the first prompt message) can be issued in response to the abnormal folding sequence of the folding screen.

[0132] for Figure 8 For the folding operation shown in (a) in FIG. 1 , the electronic device can detect that the value of α1-α2 is greater than or equal to the first threshold Th1, thereby determining that the folding order of the folding screen is normal; Figure 8 In the folding operation shown in (b), the electronic device can detect that the value of α1-α2 is less than the first threshold Th1, thereby determining that the folding order of the folding screen is abnormal.

[0133] The first threshold Th1 may be a value greater than or equal to 0, and the specific value may be set according to actual needs.

[0134] The first prompt information may include prompt information for prompting that the folding sequence is wrong, and may also include prompt information for prompting the correct folding sequence. The prompt information may include at least one of the following: interface display information, vibration information, sound information, and light information; the interface display information may include text information and / or graphic information, the sound information may be voice information or ringtone information, etc., and the light information may include light information of one or more colors.

[0135] For example, Fig.10 As shown, when the electronic device detects that the folding order of the folding screen is abnormal, it can display an interface prompt message for prompting the folding order error: "The folding order is wrong", and display an interface prompt message for prompting the correct folding order: "Please fold the right screen (i.e., screen C) first and then fold the left screen (i.e., screen A)". The interface prompt message can be displayed on a screen that is easy for the user to see according to the folding situation of the folding screen.

[0136] Some folding screens can trigger corresponding functions through folding operations at a certain angle. For example, when screen A or screen C of the folding screen is folded to a certain angle to maintain a semi-folded shape, the electronic device can be triggered to change the photo-taking or video playback layout. Therefore, in actual applications, there may be a situation where the user folds screen A of the folding screen to a certain angle to trigger the corresponding function. Taking this situation into account, in some embodiments, the electronic device can determine that the folding order of the folding screen is abnormal when it detects that α1 (i.e., the first angle) is less than the preset angle and the difference between α1-α2 (i.e., the first angle minus the second angle) is less than the first threshold Th1, so as to improve the reliability of the detection result.

[0137] For example Fig.11 As shown, during the process of the user folding screen A of the folding screen, when the angle α1 between screen A and screen B is greater than or equal to the preset angle Ta, the electronic device may not consider the folding sequence of the folding screen to be abnormal, that is, the folding sequence is considered to be normal or no abnormal judgment is made on the folding sequence; when the user continues to fold, so that the angle α1 between screen A and screen B is less than the preset angle Ta, the electronic device may determine that the folding sequence of the folding screen is abnormal.

[0138] The preset angle may be determined according to the folding angle that triggers the corresponding function. For example, the preset angle may be 90 degrees.

[0139] In addition, in some embodiments, when the first threshold Th1 is greater than 0, when the angle between screen A and screen B decreases to less than Th1 during the process of folding screen C and then folding screen A, the value of α1-α2 is less than the first threshold Th1. Considering this situation, in some embodiments, the electronic device can determine that the folding sequence of the folding screen is abnormal when it detects that α1 (i.e., the first angle) is greater than the first threshold, and the difference of α1-α2 (i.e., the first angle minus the second angle) is less than the first threshold Th1, so as to reduce the occurrence of false triggering and improve the reliability of the detection results. In some embodiments, the occurrence of such false triggering can also be reduced by anti-false touch detection such as abnormal duration detection or touch detection similar to the abnormal duration detection or touch detection described later.

[0140] The second method is to detect whether the folding order of the folding screen is abnormal based on the magnetic induction relationship between adjacent screens in the folding screen.

[0141] Specifically, one of the first screen and the second screen can be correspondingly provided with a first magnet, the other can be correspondingly provided with a Hall sensor, and the third screen of the folding screen can be correspondingly provided with a second magnet; in the folded form, the first magnet, the second magnet and the Hall sensor are positioned correspondingly in the thickness direction of the folding screen, the first pole of the first magnet and the second pole of the second magnet are facing the Hall sensor, and the polarity of the first pole is opposite to that of the second pole; the electronic device can determine that the folding order of the folding screen is abnormal when the Hall sensor senses the approach of the first pole but does not sense the second pole.

[0142] For example, Fig.12 As shown in (a), a Hall sensor H is provided in the shell corresponding to the A screen (i.e., the first screen), a first magnet M1 is provided in the shell corresponding to the B screen, and a second magnet M2 is provided in the shell corresponding to the C screen; in the folded form, that is, after the folding screen is folded in the correct folding order, the first magnet M1, the second magnet M2 and the Hall sensor H are positioned in a corresponding manner in the thickness direction of the folding screen (here, exemplarily, the Hall sensor H is located on the side of the A screen away from the B screen), and the S pole of the first magnet M1 (i.e., the first magnetic pole) and the N pole of the second magnet M2 (i.e., the second magnetic pole) face the Hall sensor H. Among them, the first magnet M1, the second magnet M2 and the Hall sensor H are positioned in a corresponding manner in the thickness direction of the folding screen, and specifically, the projections of the first magnet M1, the second magnet M2 and the Hall sensor H on the B screen overlap, and the projections of the three projections may overlap in whole or in part.

[0143] Continue to refer to Fig.12 In (a), if the user folds the folding screen in the correct folding order, that is, folds screen C first and then screen A, then after the user folds screen C, during the process of folding screen A, the Hall sensor H can sense that the N pole of the second magnet M2 is approaching; under the shielding effect of the second magnet M2, the Hall sensor H cannot sense the S pole of the first magnet M1, or the magnetic field strength of the sensed S pole of the first magnet M1 is relatively weak.

[0144] like Fig.12 As shown in (b), if the user folds the folding screen in the wrong folding order, that is, folds screen A first and then screen C, then during the process of the user folding screen A, the Hall sensor H can sense the approach of the S pole of the first magnet M1, but because screen C is not folded, the Hall sensor H cannot sense the N pole of the second magnet M2. At this time, the electronic device can determine that the folding order of the folding screen is abnormal.

[0145] For example, Fig.13As shown in (a), a first magnet M1 is arranged in the shell corresponding to screen A, a Hall sensor H is arranged in the shell corresponding to screen B (i.e., the second screen), and a second magnet M2 is arranged in the shell corresponding to screen C; in the folded form, i.e., after the folding screen is folded in the correct folding order, the first magnet M1, the second magnet M2 and the Hall sensor H are positioned correspondingly in the thickness direction of the folding screen (here exemplarily, the Hall sensor H is located on the side of screen B close to screen C), and the N pole (i.e., the first magnetic pole) of the first magnet M1 and the S pole (i.e., the second magnetic pole) of the second magnet M2 are facing the Hall sensor H.

[0146] Continue to refer to Fig.13 In (a), if the user folds the folding screen in the correct folding order, that is, folds the C screen first and then the A screen, the Hall sensor H can sense that the S pole of the second magnet M2 is approaching during the process of the user folding the C screen; after the user folds the C screen, during the process of folding the A screen, the Hall sensor H cannot sense the N pole of the first magnet M1 due to the obstruction of the second magnet M2, or the magnetic field strength of the N pole of the first magnet M1 sensed is relatively weak.

[0147] like Fig.13 As shown in (b), if the user folds the folding screen in the wrong folding order, that is, folds screen A first and then screen C, then during the process of the user folding screen A, the Hall sensor H can sense the approach of the N pole of the first magnet M1, but because screen C is not folded, the Hall sensor H cannot sense the S pole of the second magnet M2. At this time, the electronic device can determine that the folding order of the folding screen is abnormal.

[0148] Among them, when the magnetic field of the second magnet M2 is strong and is close to the Hall sensor H, when the C screen is unfolded, the Hall sensor H may sense the S pole of the second magnet M2. In this case, the positions of the first magnet M1, the second magnet M2 and the Hall sensor H can be adjusted so that in the unfolded form, the Hall sensor H cannot sense the second magnet M2; or when the Hall sensor H senses the proximity of the N pole of the first magnet M1, it can be further determined whether the magnetic field strength of the S pole of the second magnet M2 sensed by the Hall sensor H reaches a certain strength (referred to as the first strength here). If the first strength is not reached, it is considered that the folding order of the folding screen is abnormal, so as to further improve the accuracy of the detection result, wherein the first strength can be greater than the magnetic field strength of the S pole of the second magnet M2 that can be sensed by the Hall sensor H in the unfolded form.

[0149] As mentioned above, for a Fig.12 and Fig.13In the arrangement of the Hall sensor and the magnet shown, when the user folds the C screen and then folds the A screen in the correct folding order, the Hall sensor H cannot sense the first magnetic pole of the first magnet M1 or the magnetic field strength of the first magnetic pole of the first magnet M1 sensed is relatively weak due to the shielding effect of the second magnet M2; when the user folds the A screen first in the wrong folding order, the Hall sensor H can sense the first magnetic pole of the first magnet M1, and as the A screen approaches the B screen, the magnetic field strength of the first magnetic pole of the first magnet M1 sensed by the Hall sensor H can exceed the magnetic field strength of the first magnetic pole of the first magnet M1 that the Hall sensor H can sense in the folded form. Based on this, in some embodiments, when detecting whether the folding order is abnormal, the electronic device can also determine that the folding order of the folding screen is abnormal when the Hall sensor senses that the first magnetic pole is close and the magnetic field strength of the sensed first magnetic pole is greater than a preset strength. Wherein, the preset strength can be greater than the magnetic field strength of the first magnetic pole of the first magnet M1 that the Hall sensor H can sense in the folded form. This implementation method has relatively high accuracy. The above-mentioned implementation method of "determining that the folding order of the folding screen is abnormal when the Hall sensor senses the approach of the first magnetic pole but does not sense the second magnetic pole" has higher detection timeliness and can be selected as needed during specific implementation.

[0150] It is understandable that the specific position and polarity setting of the first magnet, the second magnet and the Hall sensor are only examples, and are not intended to limit the present application. The three only need to satisfy the position relationship and polarity relationship under the folded form. Fig.12 As shown in (a), in the folded state, the Hall sensor H, the first magnet M1 and the second magnet M2 are correspondingly arranged on the right side of the folding screen. In other embodiments, the Hall sensor H, the first magnet M1 and the second magnet M2 may also be correspondingly arranged in other positions such as the middle or left side of the folding screen; in other embodiments, in the folded state, the N pole of the first magnet M1 (i.e., the first magnetic pole) and the S pole of the second magnet M2 (i.e., the second magnetic pole) may also be facing the Hall sensor H.

[0151] like Fig.14 As shown, the Hall sensor H can be connected to two ports of the processor in the electronic device through two output terminals OUT1 and OUT2, wherein the Hall sensor H can output a first electrical signal (e.g., a high-level signal) to the processor through the output terminal OUT1 when sensing the S pole, and output a second electrical signal (e.g., a high-level signal) to the processor through the output terminal OUT2 when sensing the N pole. Correspondingly, the processor of the electronic device can determine the sensing result of the Hall sensor through the received electrical signal, for example, for the above Fig.12In the structure shown in , the electronic device can determine that the Hall sensor H senses the S pole of the first magnet M1 when the processor receives the first electrical signal. If the processor continues to receive the first electrical signal within a recent period of time (target duration), and the duration is less than the target duration, it can be determined that the Hall sensor H senses the S pole of the first magnet M1 is approaching.

[0152] The Hall sensor H may also output electrical signals of different magnitudes according to the strength of the induced magnetic field. For example, the stronger the induced magnetic field strength, the greater the level of the output electrical signal. Based on this, the processor may also determine that the Hall sensor H senses that the S pole of the first magnet M1 is close when the first electrical signal is continuously received in the recent period of time and the value of the received first electrical signal gradually increases.

[0153] In some embodiments, a magnet may be provided corresponding to one of the first screen and the second screen, and a Hall sensor may be provided corresponding to the other; in the folded form, the magnet and the Hall sensor may correspond to each other in the thickness direction of the folding screen; the electronic device may determine that the folding order of the folding screen is abnormal when the Hall sensor senses the magnet and the sensed magnetic field strength is greater than the target strength.

[0154] The target intensity can be determined according to the actual required sensing sensitivity, and the specific size is not particularly limited in the embodiment of the present application.

[0155] For example, Fig.15 As shown in (a), a Hall sensor H is provided in the shell corresponding to screen A, and a magnet M is provided in the shell corresponding to screen B; in the folded form, that is, after the folding screen is folded in the correct folding order, the magnet M and the Hall sensor H are positioned correspondingly in the thickness direction of the folding screen (here, illustratively, the Hall sensor H is located on the side of screen A away from screen B). If the user folds the folding screen in the correct folding order, that is, folds screen C first and then screen A, then after the user folds screen C, during the folding process of screen A, the Hall sensor H cannot sense the magnet M due to the shielding effect of screen C, or the magnetic field intensity of the sensed magnet M is very small. Among them, the magnet M and the Hall sensor H are positioned correspondingly in the thickness direction of the folding screen, and specifically, the projections of the magnet M and the Hall sensor H on screen B completely or partially overlap.

[0156] like Fig.15 As shown in (b), if the user folds the folding screen in the wrong folding order, that is, folds screen A first and then screen C, the Hall sensor H can sense the magnet M during the process of the user folding screen A, and as screen A approaches screen B, the Hall sensor H can sense a relatively strong magnetic field strength. When the magnetic field strength sensed by the Hall sensor is greater than the target strength, the electronic device can determine that the folding order of the folding screen is abnormal.

[0157] For example, Fig.16 As shown in (a), a magnet M is set in the shell corresponding to screen A, and a Hall sensor H is set in the shell corresponding to screen B; in the folded form, that is, after the folding screen is folded in the correct folding order, the magnet M and the Hall sensor H are located in corresponding positions in the thickness direction of the folding screen (here, for example, the Hall sensor H is located on the side of screen B close to screen C). If the user folds the folding screen in the correct folding order, that is, folds screen C first and then screen A, then after the user folds screen C, during the folding of screen A, the Hall sensor H cannot sense the magnet M due to the shielding effect of screen C, or the magnetic field strength of the sensed magnet M is very small.

[0158] like Fig.16 As shown in (b), if the user folds the folding screen in the wrong folding order, that is, folds screen A first and then screen C, the Hall sensor H can sense the magnet M during the process of the user folding screen A, and as screen A approaches screen B, the Hall sensor H can sense a relatively strong magnetic field strength. When the magnetic field strength sensed by the Hall sensor is greater than the target strength, the electronic device can determine that the folding order of the folding screen is abnormal.

[0159] for Fig.12 and Fig.15 As shown in the figure, a Hall sensor is arranged on the housing corresponding to the A screen, and a magnet with strong magnetism is arranged on the housing corresponding to the C screen, and no magnet is arranged on the housing corresponding to the B screen. Fig.12 The magnet corresponding to screen B is removed. Correspondingly, when the folding order of the folding screen is correct, the Hall sensor on the shell corresponding to screen A can sense the N pole of the magnet on the shell corresponding to screen C; when the folding order of the folding screen is wrong, the Hall sensor on screen A can sense the S pole of the magnet on the shell corresponding to screen C, and its magnetic field strength is relatively weak.

[0160] It can be understood that the setting of the magnet and the Hall sensor is not limited to the above example. In some embodiments, multiple Hall sensors can also be set to respectively sense the posture of screen C relative to screen B and the posture of screen A relative to screen B. The specific folding sequence detection principle is similar and will not be repeated here.

[0161] In addition, the way in which the electronic device detects whether the folding order of the folding screen is abnormal is not limited to the above example, that is, the electronic device may also use other implementation methods to detect whether the folding order of the folding screen is abnormal.

[0162] Considering that there may be false triggers when the user uses the folding screen, in order to improve the accuracy of the control results and enhance the user experience, in some embodiments of the present application, the electronic device can detect that the folding order of the folding screen is abnormal, and issue a first prompt message when the first target condition is met. When the user performs the folding operation, it will last for a certain period of time; in addition, the user generally touches some areas of the display screen. Based on this, in the embodiments of the present application, the first target condition may include: detecting that the duration of the abnormal folding order reaches the first duration, or detecting a touch operation acting on the first target area.

[0163] Among them, the first duration can be several seconds, and the specific size can be set as needed, and the embodiment of the present application does not specifically limit this; the first target area can be, for example, the edge area of ​​screen A, and the specific position can also be set as needed.

[0164] In some embodiments, the electronic device may also use the above two folding sequence abnormality detection methods at the same time, and issue a first prompt message when the folding sequence abnormality is detected by both of the above two methods. That is, the first target condition may include: the duration of the folding sequence abnormality reaches the first duration, or a touch operation acting on the first target area is detected, or the folding sequence abnormality is detected by multiple detection methods.

[0165] Considering that when the user folds the folding screen, there may be a reverse folding (referred to as reverse folding), for example, Figure 1 The folding screen shown in the figure, when folded, the correct folding method is that screen A and screen B are folded outwards, but the user may mistakenly fold screen A and screen B in the opposite direction, that is, fold them inwards. In order to help users fold the electronic device in the correct folding direction and reduce the impact of the folding on the life of the electronic device, in some embodiments of the present application, the electronic device may also provide a folding detection function, through which the operation acting on the folding screen for changing the angle between adjacent screens of the folding screen (referred to as the target operation here) is detected to be folded back, and a prompt message (referred to as the second prompt message here) is issued when it is detected that the folding screen is folded in the opposite direction. The process is described in detail below.

[0166] Fig.17 A flow chart of another folding screen control method provided in an embodiment of the present application is shown as follows: Fig.17 As shown, the method may include the following steps:

[0167] S210: Receive a target operation acting on the folding screen.

[0168] The target operation is used to change the angle between adjacent screens of the folding screen, which may include an expansion operation (corresponding to increasing the angle between adjacent screens of the folding screen), wherein the expansion operation may include a normal expansion operation, or an abnormal expansion operation, or a folding operation with an abnormal folding direction, i.e., a reverse folding operation. Of course, the target operation may also include a folding operation with a normal folding direction, i.e., any operation that changes the angle between adjacent screens of the folding screen may be subjected to reverse folding detection.

[0169] The adjacent screens may be any two adjacent screens of the folding screen, which are referred to as the first target screen and the second target screen. Figure 1 For the folding screen shown in , the first target screen and the second target screen may be screen A and screen B; Figure 2 In the folding screen shown in , the first target screen and the second target screen can be screen A and screen B, or screen B and screen C.

[0170] Similar to step S120, the electronic device can detect the target operation by detecting the change in the angle of the folding screen or through related switches, etc. The specific implementation method is similar and will not be repeated here.

[0171] S220. In response to the target operation, when it is detected that the folding screen is folded in the reverse direction, a second prompt message is issued.

[0172] Among them, the folding axis between the first target screen and the second target screen can be called the target folding axis. Under normal folding operation, the first target screen and the second target screen can be folded around the target folding axis in a first direction; when the electronic device detects that the first target screen and the second target screen are folded in the second direction, it means that the folding screen is detected to be folded in the opposite direction, wherein the second direction is the opposite direction of the first direction.

[0173] For example, for Figure 1 In the folding screen shown in , when folded, screen A and screen B can be folded outward around the folding axis (i.e. folded in the outward folding direction). When the electronic device detects that screen A and screen B are folded inward around the folding axis (i.e. folded in the inward folding direction), it means that the folding screen is detected to be folded in the reverse direction. Figure 2 In the folding screen shown in the figure, screen A and screen B can be folded inwardly around folding axis 1, and screen B and screen C can be folded inwardly around folding axis 2. The target operation can be used to change the angle between screen A and screen B, or to change the angle between screen B and screen C. When the electronic device detects that screen A and screen B fold outwardly around folding axis 1, or detects that screen B and screen C can fold outwardly around folding axis 2, it means that the folding screen is detected to be folded in the opposite direction.

[0174] The electronic device may perform a folding detection on every two adjacent screens in the folding screen, and may issue a second prompt message when any two adjacent screens are detected to be folded. Figure 1 For the folding screen shown in , the electronic device can detect the angle between screen A and screen B to determine whether screen A is folded relative to screen B; Figure 2 For the folding screen shown in the figure, the electronic device can detect the angle between screen A and screen B, and the angle between screen B and screen C to determine whether screen A is folded relative to screen B and whether screen C is folded relative to screen B.

[0175] Below Figure 1 Taking the folding screen in as an example, two implementation methods of detecting the reverse folding of the folding screen are illustrated.

[0176] The first method is to detect whether the folding screen is folded based on the angle between adjacent screens in the folding screen.

[0177] When two adjacent screens of the folding screen are folded back, the angle between the two adjacent screens is likely to exceed 180°. Based on this, the electronic device can determine that the folding screen is folded back when it detects that the angle between adjacent screens of the folding screen is greater than a preset threshold (hereinafter referred to as the second threshold) Th2, wherein the second threshold is greater than 180°, for example, it can be 185°, and the specific size can be determined according to the required detection sensitivity, and the embodiment of the present application does not specifically limit this.

[0178] Among them, the way in which the electronic device detects the angle between adjacent screens can be found in the relevant description in the above step S120, which will not be repeated here.

[0179] For example, Fig.18 As shown, the folding method of the folding screen is outward folding. When the user folds the folding screen, the folding direction is wrong, that is, screen A and screen B are folded inward. At this time, the angle α between screen A and screen B gradually increases from 180° under the action of the user's folding force. When the electronic device detects that α>Th2, it can be determined that the folding screen is folded back.

[0180] The second method is to detect whether the folding screen is folded back based on the pressure between adjacent screens in the folding screen.

[0181] Specifically, a pressure sensor can be set between adjacent screens of the folding screen. When two adjacent screens of the folding screen are folded back, the relative parts of the two adjacent screens will squeeze each other and increase the pressure. Based on this, the electronic device can determine that the folding screen is folded reversely when the pressure detected by the pressure sensor is greater than the pressure threshold.

[0182] The pressure sensor may be a piezoelectric or piezoresistive pressure sensor, and the pressure sensor may be disposed on a side wall of a housing where one of the adjacent screens is located relative to the other screen, or may be disposed between one of the adjacent screens and the folding axis, or may be disposed on the folding axis or on a structure such as a middle frame. For example, Fig.19 As shown, the pressure sensor P is arranged on the folding axis between the A screen and the B screen.

[0183] The pressure threshold can be determined according to the required detection sensitivity and is not particularly limited here.

[0184] Continue to see Fig.19 The folding method of the folding screen is outward folding. When the user folds the folding screen, that is, folds screen A and screen B inward, the pressure sensor P between screen A and screen B is squeezed by screen B, and the pressure detected by it becomes larger. When the pressure detected by the pressure sensor is greater than the pressure threshold, it can be determined that the folding screen is folded back.

[0185] As described above, when the electronic device detects that the folding screen is folded back, it can send a second prompt message in response to the folding screen being folded back. Similar to the first prompt message, the second prompt message may include prompt message for prompting that the folding direction is wrong, and may also include prompt message for prompting the correct folding direction. The prompt message may include at least one of the following: interface display information, vibration information, sound information, and light information.

[0186] For example, Fig. 20 As shown, when the electronic device detects that the folding screen is folded back, it can display an interface prompt message for prompting the wrong folding direction: "The folding direction is wrong", and display an interface prompt message for prompting the correct folding direction: "Please fold outwards". The interface prompt message can be displayed on a screen that is easy for the user to see according to the folding condition of the folding screen.

[0187] It is understandable that the way in which the electronic device detects whether the folding screen is folded is not limited to the above example, that is, the electronic device may also use other implementation methods to detect whether the folding screen is folded.

[0188] Similar to the abnormal folding sequence detection process, in order to reduce false triggering, improve the accuracy of control results, and enhance user experience, in some embodiments of the present application, the electronic device can detect that the folding screen is folded back, and, if the second target condition is met, issue a second prompt message. When the user performs the folding operation, it will last for a certain period of time; in addition, the user generally touches some areas of the display screen. Based on this, in the embodiments of the present application, the second target condition may include: detecting that the duration of the reverse folding state reaches a second duration, or detecting a touch operation acting on the second target area.

[0189] Among them, the second time length can be several seconds, and the specific size can be set as needed. The embodiment of the present application does not specifically limit this; the second target area can be, for example, the edge area of ​​the folding screen, which can be the same as or different from the second target area, and the specific position can be set as needed.

[0190] In some embodiments, the electronic device may also use the above two reverse folding detection methods at the same time, and issue a second prompt message when the folding sequence is detected to be abnormal using the above two methods. That is, the second target condition may include: the duration of the reverse folding state reaches the second duration, or a touch operation acting on the second target area is detected, or the folding screen is detected to be reversed using multiple detection methods.

[0191] It can be understood that the naming of various terms in the embodiments of the present application is only an example and should not be understood as a limitation on the embodiments of the present application. In some embodiments, the same terms may also be named by other names. For example, the pressure threshold may also be called the third threshold.

[0192] It should also be understood that any one of the above examples or the solution shown in any one of the figures may be an independent solution, or a solution composed of any multiple examples or a solution composed of any multiple figures may also be an independent solution, and this application does not impose any special restrictions on this.

[0193] Those skilled in the art can understand that the above embodiments are exemplary and are not intended to limit the present application. Where possible, the above steps can also be selectively combined to obtain one or more other embodiments. For example, in some embodiments, steps S110 to S120 and steps S210 to S220 can be combined to form one or more embodiments, wherein the execution order of each step can be adjusted, and steps S210 to S220 can be executed after steps S110 to S120, or before steps S110 to S120, or in parallel with steps S110 to S120; for another example, in some embodiments, steps S120 and steps S210 to S220 can also be combined, that is, after receiving the target operation acting on the folding screen, the electronic device can perform steps S120 and S220 for folding sequence detection and reverse folding detection for the operation, or, for a multi-fold folding screen, step S120 can be performed when the target operation is detected to be a folding operation, and for a folding screen including at least two screens, step S220 can be performed when the target operation is detected to be an unfolding operation. Those skilled in the art can select and combine any of the above steps as needed, and all combinations that do not deviate from the essence of the present application scheme shall fall within the protection scope of the present application.

[0194] The folding screen control method provided in this embodiment is that the electronic device can respond to the folding operation of the user after receiving the folding operation of the folding screen, and issue a prompt message when it detects that the folding order of the folding screen is abnormal. This can help the user fold in the correct folding order, improve the user's operating experience, and reduce the impact of user folding errors on the service life of the electronic device.

[0195] In addition, after receiving the user's target operation on the folding screen (used to change the angle between adjacent screens of the folding screen), the electronic device can respond to the target operation and issue a prompt message when it detects that the folding screen is folded. This can help the user fold it in the correct folding direction, improve the user's operating experience, and reduce the impact of user folding errors on the service life of the electronic device.
