Patent Description:
With rapid development of the mobile phone terminal industry, foldable mobile phones have become a new development trend. The foldable mobile phone usually includes an outer screen and an inner screen. To protect the foldable mobile phone, the foldable mobile phone is usually equipped with a protective case. The protective case may cover a surface of the outer screen when the foldable mobile phone is in a folded state. When using the foldable mobile phone, a user is accustomed to first viewing information on the outer screen, then covering the surface of the outer screen with the protective case, and then opening the inner screen. A flip cover mode is triggered when the protective case covers the surface of the outer screen. In the flip cover mode, an unlocking function is enabled on the foldable mobile phone. Therefore, unlocking is further required to open the inner screen, affecting operation efficiency and use experience of the user. <CIT> discloses a protective case for foldable image display devices that shields hinges and screens from damage while maintaining device functionality. <CIT> discloses a cover for electronic devices that enables selective screen viewing and controls device functions based on cover placement. <CIT> discloses a foldable protective case for foldable electronic devices, providing screen protection and additional functionalities including locking and wake-up features. <CIT> discloses a method for display control in foldable-screen devices.

This application provides an electronic device display method and an electronic device, so that a non-lock screen can be directly entered when a user switches from an outer screen to an inner screen, thereby improving browsing efficiency and use experience of the user.

An electronic device display method is provided. The electronic device includes a foldable body, an outer screen, and an inner screen, the outer screen and the inner screen are respectively located on two opposite surfaces of the foldable body, and the method includes:.

In this embodiment, when a user covers the outer screen with the protective cover, and the foldable body is switched from the folded state to the non-folded state, the user probably needs to browse through the outer screen. Therefore, when the user opens the inner screen, the user does not need to perform unlocking, and the electronic device directly enters the screen non-locked state, so that browsing efficiency and browsing experience of the user are improved.

In an embodiment, a signal transmitting component is disposed on the protective cover, and a signal sensing component is disposed on the outer screen; and when the protective cover approaches the outer screen, and the signal sensing component senses a signal transmitted by the signal transmitting component, it is determined that the protective cover reaches the preset position.

In an embodiment, if the foldable body is not switched to the non-folded state within the preset time after the protective cover reaches the preset position, the electronic device is controlled to be in a screen locked state.

In an embodiment, that the preset condition is met further includes: the electronic device is in the screen non-locked state.

In this embodiment, when it is determined that the electronic device is in the screen non-locked state, it indicates that the user browses the outer screen when the electronic device is in the screen non-locked state. Based on a use habit of the user, if the protective cover covers a surface of the outer screen in this case, it indicates that the user may perform an operation of unfolding the inner screen next, and further browse displayed content of the outer screen through the inner screen. Therefore, a processor may invoke a function of delaying screen locking, and determine, based on a next action of the user, whether to lock a screen of the mobile phone.

In an embodiment, if the electronic device is in a screen locked state, the electronic device is controlled to remain in the screen locked state.

In an embodiment, if the electronic device is in the screen non-locked state, the outer screen displays a non-lock screen; and if it is determined that the foldable body is switched to the non-folded state, the inner screen is controlled to continue to display the non-lock screen.

In this embodiment, browsing continuity experience when the user switches from the outer screen to the inner screen can be improved.

In an embodiment, that the preset condition is met further includes: a posture of the foldable body is in a non-horizontal state.

In this embodiment, when the user normally views the electronic device, the electronic device is tilted with respect to a horizontal plane in most cases. If the foldable mobile phone is horizontally placed, it indicates that the user may not view the inner screen next. Therefore, determining accuracy can be improved.

In an embodiment, it is determined whether an absolute value of a change amount of a roll angle of the foldable body is greater than a first preset angle; and if the absolute value of the change amount of the roll angle of the foldable body is greater than the first preset angle, it is determined that the posture of the foldable body is in the non-horizontal state, where a rotation axis corresponding to the roll angle is parallel to a folding axis of the foldable body.

In this embodiment, if the absolute value of the roll angle of the foldable body is greater than the first preset angle, it indicates that the user is probably preparing to unfold the inner screen. Therefore, it may be considered that the user is to open the inner screen next to continue browsing.

In an embodiment, before it is determined whether the absolute value of the change amount of the roll angle of the foldable body is greater than the first preset angle, the method further includes:.

In this embodiment, if the absolute value of the pitch angle of the foldable body is less than the second preset angle, or the component of the acceleration sensor in the foldable body in the gravity direction is less than the preset threshold, it indicates that the roll angle obtained in this case can relatively accurately reflect the posture of the foldable body. Therefore, an intention of the user may be further determined from the posture of the foldable body.

In an embodiment, if the absolute value of the pitch angle of the foldable body is not less than the second preset angle, or the component value of the acceleration sensor in the foldable body in the gravity direction is not less than the preset threshold, it is determined, within the preset time after the protective cover reaches the preset position, whether the foldable body is switched to the non-folded state.

In an embodiment, after the protective cover reaches the preset position with respect to the outer screen, the method includes: controlling the outer screen to display a small-window interface.

In an embodiment, after it is determined, within the preset time after the protective cover reaches the preset position, that the foldable body is switched to the non-folded state, the method further includes: controlling the outer screen to exit the small-window interface.

In this embodiment, if the user indeed does not open the inner screen to continue browsing, the user may also quickly browse information such as time and a short messaging service message through a small window on the outer screen, so that browsing continuity experience of the user is improved.

In an embodiment, after the foldable mobile phone <NUM> enables the flip cover mode, the foldable mobile phone <NUM> may invoke a screen locking function while the outer screen <NUM> displays the small-window interface.

For example, the foldable mobile phone <NUM> may trigger the flip cover mode in the following manner:.

A signal transmitting component (not shown in the figure) may be disposed on the protective cover <NUM>, and a signal sensing component (not shown in the figure) may be disposed on the first body <NUM> or the outer screen <NUM>. When the protective cover <NUM> approaches and covers the outer screen <NUM>, so that the signal sensing component senses a signal transmitted by a signal transmitter, the signal sensing component may send an interrupt trigger signal to the processor of the foldable mobile phone <NUM>. The processor may invoke the screen locking function based on the interrupt trigger signal. In this case, the outer screen <NUM> may display the lock screen, and the inner screen <NUM> may be in the power-off and screen-off state.

In an embodiment, a position at which the signal sensing component can sense the signal transmitted by the signal transmitter may be a relative position of the signal transmitting component and the signal sensing component when the protective cover <NUM> covers the outer screen <NUM>. Alternatively, a position at which the signal sensing component can sense the signal transmitted by the signal transmitter may be a position at which the signal sensing component can just sense the signal transmitted by the signal transmitting component and at which the protective cover <NUM> and the outer screen <NUM> are not completely attached, in other words, there is still a specific angle between the protective cover <NUM> and the outer screen <NUM> when the protective cover <NUM> approaches the outer screen <NUM>.

In an embodiment, the signal transmitting component may include a magnet (not shown in the figure) disposed on the protective cover <NUM>. The signal sensing component may be a Hall effect sensor (not shown in the figure) disposed on the outer screen <NUM>. In an embodiment, the Hall effect sensor may be disposed at an upper left corner of the outer screen <NUM>. When the protective cover <NUM> covers the outer screen <NUM>, a position of the magnet is opposite to that of the Hall effect sensor disposed on the outer screen <NUM>. When the protective cover <NUM> approaches the outer screen <NUM>, the Hall effect sensor may detect a change of a magnetic field. When a magnetic flux detected by the Hall effect sensor reaches a magnetic flux threshold, the Hall effect sensor may send an interrupt trigger signal to the processor.

In some embodiments, when the user needs to browse the outer screen <NUM>, the user usually lifts the protective cover <NUM>. In this case, the signal transmitting component may send a signal to the signal sensing component, and the processor may control, based on the signal received by the signal sensing component, the foldable mobile phone <NUM> to exit the screen locked state. In an embodiment, the foldable mobile phone <NUM> may alternatively be set to a mode in which the user manually unlocks the foldable mobile phone <NUM>. In other words, after lifting the protective cover <NUM>, the user may manually unlock the foldable mobile phone <NUM>.

When the user uses the foldable mobile phone <NUM>, the following cases usually occur:
Case <NUM>: The foldable mobile phone <NUM> is in the screen locked state when not in use. When there is an information reminder of applications such as Email, WeChat, or QQ on the foldable mobile phone <NUM>, a pop-up window, a vibration, or a voice prompt occurs on the foldable mobile phone <NUM>. The user usually lifts the protective cover <NUM>, and simply browses information content through the outer screen <NUM>.

Further referring to <FIG>, the foldable mobile phone <NUM> is still in the screen locked state after the protective cover <NUM> is lifted. If a further operation or further browsing needs to be performed by using the inner screen <NUM>, the inner screen <NUM> needs to be opened and unlocking needs to be performed to perform a next operation.

Case <NUM>: When the user unlocks the foldable mobile phone <NUM>, and then browses content such as a video or a website or reads a book, a report, or a picture through the outer screen <NUM>, if an image displayed on the outer screen <NUM> is relatively small and affects browsing experience, the user further switches to the inner screen <NUM> for further browsing.

Referring to <FIG>, in this case, before the outer screen <NUM> is switched to the inner screen <NUM>, because the user is browsing content of an application in the foldable mobile phone <NUM>, the user has performed an unlocking operation, and therefore the foldable mobile phone <NUM> is in a screen unlocked state.

In both Case <NUM> and Case <NUM>, the user first browses through the outer screen <NUM>, and then switches to the inner screen <NUM> for further browsing. When switching from the outer screen <NUM> to the inner screen <NUM>, the user usually performs the following operations on the foldable mobile phone <NUM>:
Further referring to <FIG>, first, the user holds the foldable mobile phone <NUM> with a right hand, and covers, with a left hand on the surface of the outer screen <NUM> in a direction indicated by an arrow, the protective cover <NUM> lifted through rotation about the rotating shaft <NUM>.

Referring to <FIG>, when the protective cover <NUM> covers the outer screen <NUM>, an operation is performed on the foldable body <NUM> with the right hand to enable the foldable body <NUM> to rotate about a folding axis <NUM>, so that the outer screen <NUM> also synchronously approaches the protective cover <NUM>. In this process, a thumb of the left hand approaches an end of the first body <NUM> and an end of the second body <NUM> that are away from the rotating shaft <NUM>.

Referring to <FIG>, after the thumb of the left hand and a thumb of the right hand of the user respectively touch the end of the first body <NUM> and the end of the second body <NUM> that are away from the rotating shaft <NUM>, the thumb of the left hand and the thumb of the right hand of the user cooperate to press end surfaces that are of the first body <NUM> and the second body <NUM> and that are away from the rotating shaft <NUM> and forcibly make the first body <NUM> and the second body <NUM> rotate about the rotating shaft <NUM> in arrow directions and be unfolded.

As shown in <FIG>, the foldable mobile phone <NUM> finally stays in the unfolded state, and in this case, the inner screen <NUM> is unfolded to face the user. In this case, the inner screen <NUM> may be displayed as a lock screen.

Referring to <FIG>, for Case <NUM>, after the user opens the outer screen <NUM> to browse the reminder information, and before the inner screen <NUM> is unfolded and the foldable mobile phone <NUM> is unlocked, the foldable mobile phone <NUM> is usually in the screen locked state. Therefore, after opening the inner screen <NUM>, the user needs to manually perform unlocking before further browsing information. This increases user operation steps, and affects browsing efficiency and browsing experience.

In an embodiment, in an operation process shown in <FIG> (excluding <FIG>), when the protective cover <NUM> approaches and covers the outer screen <NUM>, so that the signal sensing component senses a signal transmitted by the signal transmitter, the signal sensing component may send an interrupt trigger signal to the processor of the foldable mobile phone <NUM>. In this case, the foldable mobile phone <NUM> is in the screen locked state, and the screen locking function does not need to be re-invoked. Therefore, the foldable mobile phone <NUM> still remains in the screen locked state.

For Case <NUM>, when the user browses the outer screen <NUM>, the user has performed an unlocking operation, and the foldable mobile phone <NUM> is in the screen non-locked state. In the steps shown in <FIG> and <FIG>, when the user performs an operation of covering the protective cover <NUM> on the outer screen <NUM>, the protective cover <NUM> covers the surface of the outer screen <NUM>, and the processor may invoke the screen locking function based on an interrupt trigger signal. Therefore, even in a case in which the outer screen <NUM> is in the screen non-locked state, when the mobile phone is switched from the folded state to the unfolded state, the inner screen <NUM> is in the locked state after being powered on. The user needs to further perform an unlocking operation before browsing, through the inner screen <NUM>, content displayed on the outer screen <NUM>. This affects continuity of continuing to browse the content on the outer screen <NUM> by the user through the inner screen <NUM>, and reduces browsing efficiency.

Therefore, it can be learned from the foregoing embodiment that, during use of the foldable mobile phone <NUM>, if the user needs to switch to the inner screen <NUM> for further browsing after the user performs operations of opening the protective cover <NUM> and then covering the protective cover <NUM> on the outer screen <NUM>, because the inner screen <NUM> is usually in the screen locked state, as shown in <FIG>, when further browsing needs to be performed by using the inner screen <NUM>, an unlocking step usually needs to be performed again. This reduces browsing efficiency of the user.

It may be understood that the foregoing case is merely an example for description, and does not constitute a limitation on a specific use scenario of the foldable mobile phone <NUM>.

It can be learned from the foregoing use scenario of the user that, in the process in which the user covers the outer screen <NUM> with the protective cover <NUM> and then unfolds the inner screen <NUM>, the foldable mobile phone <NUM> has a specific posture, and the user also has a specific action. A specific contact position also exists between the foldable mobile phone <NUM> and the hand of the user. Therefore, the foldable mobile phone <NUM> may be configured, so that the foldable mobile phone <NUM> can sense the specific gesture, the specific position, or the specific contact position, and the foldable mobile phone <NUM> enters the screen non-locked state when the inner screen <NUM> is unfolded, to omit the unlocking step of the user and improve browsing efficiency of the user.

In an embodiment, a signal may be sent to the processor when a position or pressing pressure of the hand relative to the first body <NUM> and the second body <NUM> changes in a process in which the user performs an operation on the mobile phone to unfold the inner screen <NUM>. The processor controls the foldable mobile phone <NUM> to enter the screen non-locked state, so that the user omits the unlocking operation when switching from the outer screen <NUM> to the inner screen <NUM> for viewing.

In an embodiment, when the user browses the outer screen <NUM>, and the foldable mobile phone <NUM> is in the screen unlocked state, after the protective cover <NUM> covers the surface of the outer screen <NUM>, the processor may not invoke the screen locking function within a specific time. The processor may further determine whether a touch signal or a pressure signal of the hand is detected at a specific part of the first body <NUM> or the second body <NUM>. If a touch signal and a pressure signal are applied to the specific part, the user probably is to open the inner screen <NUM> next. In this case, the processor may control the foldable mobile phone <NUM> not to enter the screen locked state, and the inner screen <NUM> may synchronously display, after being powered on, content displayed on the outer screen <NUM>.

Referring to <FIG>, in an embodiment, a specific part <NUM> may be located on an end surface that is of the first body <NUM> or the second body <NUM> and that is away from the rotating shaft <NUM>. When the user needs to lift the first body <NUM> from a surface of the second body <NUM>, the thumb of the left hand and the thumb of the right hand usually press the end surfaces, so that touch and pressure are applied to the end surfaces. When a sensor on the end surface detects a touch signal or a pressure signal, the processor may control the inner screen <NUM> to be in the screen non-locked state, so that the unlocking step is skipped, thereby improving browsing experience of the user.

Referring to <FIG>, an embodiment of this application provides an electronic device display method. The method may include the following steps.

S110: Determine, when a foldable body <NUM> is in a folded state, that a protective cover <NUM> approaches an outer screen <NUM> and reaches a preset position with respect to the outer screen <NUM>.

When a user covers the outer screen <NUM> with the protective cover <NUM>, a Hall effect sensor detects a magnetic field generated by a magnet disposed on the protective cover <NUM>, and then sends an interrupt trigger signal to a processor. The preset position may be a position of the protective cover <NUM> relative to the outer screen when the Hall effect sensor can detect that a magnetic flux generated by the magnet reaches a magnetic flux threshold. In an embodiment, the preset position may be a position at which an included angle between the protective cover <NUM> and the outer screen <NUM> is <NUM>°. It may be understood that the Hall effect sensor herein is merely used as an example for description, and does not limit a type of a component that can sense a relative position relationship between the protective cover <NUM> and the outer screen <NUM>.

A scenario in which the user covers the protective cover <NUM> on the outer screen may be Case <NUM> or Case <NUM> in the foregoing embodiment. It may be understood that a use scenario of the user is not limited thereto, and the user may alternatively performs an operation of covering the protective cover <NUM> on the outer screen <NUM> in another case. For example, when the user browses a webpage, a novel, or the like through the outer screen <NUM>, the foldable mobile phone <NUM> enters a screen locked state by default after having sensed no operation of the user for a period of time. In this case, the user needs to perform an unlocking operation before further browsing. In this case, the user may choose to directly open an inner screen <NUM> to browse. In a process of opening the inner screen <NUM>, the protective cover <NUM> also covers a surface of the outer screen <NUM>.

S120: Detect, within a time t, whether the foldable body <NUM> is switched from the folded state to a non-folded state.

In the use scenario of the foregoing embodiment, after it is determined that the user covers the outer screen <NUM> with the protective cover <NUM>, it indicates that the user may perform two operations next: The first operation is to keep the protective cover <NUM> covering the surface of the outer screen <NUM>, and the user temporarily is not to browse the mobile phone. The second operation is that the user unfolds the inner screen <NUM> while covering the surface of the outer screen <NUM> with the protective cover <NUM>. If the user selects the first operation, the foldable mobile phone <NUM> may invoke a screen locking function, and then enter the screen locked state.

If the user selects the second operation, the foldable mobile phone <NUM> directly invokes the screen locking function, and to further browse through the inner screen <NUM>, the user needs to further perform an unlocking step. This affects browsing continuity experience of the user. Therefore, the time t may be reserved to delay invoking the screen locking function, an operation of the user may be detected within the time t, and it is determined, based on the operation of the user, whether to invoke the screen locking function.

In an embodiment, the non-folded state may include an unfolded state and a bracket state. The processor may determine, by detecting an included angle between a first body <NUM> and a second body <NUM>, whether the foldable body <NUM> is switched to the non-folded state. When the included angle between the first body <NUM> and the second body <NUM> is greater than a preset angle, it may be considered that the foldable mobile phone <NUM> is in the unfolded state. In this case, it may be determined that the user switches from the outer screen <NUM> to the inner screen <NUM> to continue browsing. For the preset angle, refer to the descriptions in the foregoing embodiment.

The time t may be adjusted based on a use habit of the user. In an embodiment, the time t may be <NUM> seconds. To be specific, if the user wants, after lifting the protective cover <NUM> to browse content displayed on the outer screen <NUM>, to further browse the content displayed on the outer screen <NUM> from the inner screen <NUM>, a time from covering the protective cover <NUM> on the surface of the outer screen <NUM> to separating the first body <NUM> and the second body <NUM> to unfold the inner screen <NUM> usually falls within <NUM> seconds.

When the foldable body <NUM> is switched from the folded state to the non-folded state within the time t, it indicates that the user needs to unfold the inner screen <NUM> to browse. Therefore, S130 may be performed.

It may be understood that "within the time t" may be understood as being within a preset time after the protective cover <NUM> reaches the preset position. The preset time after the protective cover <NUM> reaches the preset position may be used only as one preset condition for determining whether the foldable body <NUM> is switched to the non-folded state. In other words, there may be a plurality of preset conditions before it is determined whether the foldable body <NUM> is switched to the non-folded state. It may be understood that the plurality of preset conditions may be concurrently executed, or may have a sequential logical relationship.

S130: Skip invoking the screen locking function.

It may be understood that if the foldable body <NUM> is switched from the folded state to the non-folded state within the time t, in other words, when duration in which the foldable body <NUM> is switched from the folded state to the non-folded state is less than the time t, it may be determined not to invoke the screen locking function. In this case, the foldable mobile phone <NUM> is in a screen non-locked state. The inner screen <NUM> also displays a non-lock screen.

When it is determined that the foldable body <NUM> is switched to the non-folded state, the user probably needs to browse through the inner screen <NUM>. Therefore, the inner screen <NUM> may directly enter the screen non-locked state. When the user further opens the inner screen <NUM>, the user does not need to further perform unlocking, so that browsing efficiency and browsing experience of the user are improved.

In an embodiment, when the outer screen <NUM> displays a non-lock screen before the user covers the outer screen <NUM> with the protective cover <NUM>, the inner screen <NUM> continues to display the non-lock screen after the user opens the inner screen <NUM>. Therefore, browsing continuity experience of the user can be improved.

However, when the foldable body <NUM> always remains in the folded state within the time t, it may be determined that the user temporarily is not to browse the foldable mobile phone again, and therefore S <NUM> may be performed.

S <NUM>: Invoke the screen locking function or remain in the screen locked state.

When the user does not open the inner screen <NUM> within the time t, if the foldable mobile phone <NUM> is in the screen locked state when being in the folded state, the foldable mobile phone <NUM> continues to remain in the screen locked state. If the user does not open the inner screen <NUM> within the time t, and the foldable mobile phone <NUM> is in the unlocked state when being in the folded state, the screen locking function is invoked after the time t to perform screen locking, to avoid a misoperation and save power.

Referring to <FIG>, in an embodiment, after the determining, when a foldable body <NUM> is in a folded state, that a protective cover <NUM> approaches an outer screen <NUM> and reaches a preset position with respect to the outer screen <NUM> in S110, the electronic device display method further includes the following steps.

S102: Detect whether the foldable mobile phone is in the screen locked state.

When the protective cover <NUM> covers the outer screen <NUM>, after receiving an interrupt trigger signal, the processor detects whether the foldable mobile phone <NUM> is in the screen locked state. S140 is performed if the foldable mobile phone <NUM> is in the screen locked state; or S104 and S106 are performed if the foldable mobile phone <NUM> is in the screen non-locked state.

In some scenarios, after opening the protective cover <NUM>, the user may only view information such as time and a date through the outer screen <NUM>, but does not perform an unlocking operation, and then the user directly covers the surface of the outer screen <NUM> with the protective cover <NUM>. In this use scenario, the foldable mobile phone <NUM> is always in the screen locked state. Alternatively, in some other scenarios, after browsing the outer screen <NUM>, the user does not need to perform a further operation by using the inner screen <NUM>, but directly locks a screen of the foldable mobile phone <NUM> through a manual operation. In these scenarios, an operation of opening the inner screen <NUM> is not performed within the time t. Therefore, it can be determined that the user has no intention to unfold the inner screen <NUM>, and the foldable mobile phone <NUM> can be controlled to be in the screen locked state, in other words, the foldable mobile phone <NUM> can remain in the screen locked state.

It may be understood that, that the foldable mobile phone is in the screen non-locked state may be used as a preset condition for determining whether the foldable body <NUM> is switched to the non-folded state.

In an embodiment, the processor may determine, depending on whether the outer screen <NUM> is powered off, whether the foldable mobile phone <NUM> is in the screen locked state. In this process, the foldable mobile phone <NUM> may not enter a flip cover mode immediately.

S104: Enable a flip cover mode procedure.

When the foldable mobile phone <NUM> is in the screen non-locked state, and the protective cover <NUM> directly covers the surface of the outer screen <NUM>, the processor determines that the foldable mobile phone <NUM> is in the screen non-locked state, and the foldable mobile phone <NUM> may enable the flip cover mode procedure after receiving an interrupt trigger signal. Enabling the flip cover mode procedure may include a process of detecting whether the foldable mobile phone <NUM> is in the flip cover mode.

If it is detected, in S102, that the foldable mobile phone <NUM> is in the screen non-locked state, S104 may alternatively be skipped to perform S106. In other words, execution of S106 may not be invoked by S104.

S106: Delay invoking the screen locking function for the time t.

When the foldable mobile phone <NUM> is in the screen non-locked state, it indicates that the user browses the outer screen <NUM> when the foldable mobile phone is in the screen non-locked state. Based on a use habit of the user, if the protective cover <NUM> covers the surface of the outer screen <NUM> in this case, it indicates that the user may perform an operation of unfolding the inner screen <NUM> next, and further browse, through the inner screen <NUM>, content displayed on the outer screen <NUM>. If the foldable mobile phone <NUM> is enabled to enter the screen locked state in this case, a lock screen is displayed when the user opens the inner screen <NUM>. This certainly affects browsing experience of the user. Therefore, the processor may invoke a function of delaying screen locking, and determine, based on a next action of the user, whether to lock the screen of the foldable mobile phone <NUM>. In an embodiment, invocation of the screen locking function may be delayed by delaying invoking a screen locking application.

It may be understood that, alternatively, S104 and S106 may be synchronously performed. S106 may alternatively be performed before or after S104. S104 may not be used as a previous step of S105, and the foldable mobile phone <NUM> may run the flip cover mode after the time t.

Referring to <FIG>, in an embodiment, before the invoking delay of the screen locking function of the foldable mobile phone <NUM> in S106, the method may further include the following step:
S200: Detect whether a posture of the foldable body <NUM> is in a non-horizontal state.

It may be understood that if a plane on which the outer screen <NUM> is located is parallel to a horizontal plane when the foldable body <NUM> is in the folded state, it indicates that the user horizontally places the foldable mobile phone <NUM>. Generally, when the user normally views the foldable mobile phone <NUM>, the foldable mobile phone <NUM> is tilted with respect to the horizontal plane in most cases. If the foldable mobile phone <NUM> is horizontally placed, it indicates that the user probably is not viewing the foldable mobile phone <NUM>. Therefore, if the processor determines that the foldable mobile phone <NUM> is in a horizontal state, S140 may be directly performed to invoke the screen locking function. It may be understood that whenever an included angle of the plane on which the outer screen <NUM> is located relative to the horizontal plane falls within a threshold range, it may be considered that the foldable mobile phone <NUM> is in the horizontal state. The threshold may be an acute angle between the plane on which the outer screen <NUM> is located and the horizontal plane. In an embodiment, the threshold is less than or equal to <NUM>°. The threshold may be <NUM>°, <NUM>°, <NUM>°, or the like.

In some embodiments, it may be determined, by using an element of a gyro sensor, an acceleration sensor, or the like, whether the posture of the foldable body <NUM> is in the non-horizontal state.

It should be noted that S200 and S104 may be concurrently performed, and may be performed independently of each other. A sequence relationship between S200 and S104 is not limited herein.

If the processor determines, when the foldable body <NUM> is in the folded state, that the posture of the foldable body <NUM> is in the non-horizontal state, it indicates that the foldable mobile phone <NUM> is tilted. In this case, the user probably is to open the inner screen <NUM> to continue browsing. Therefore, S106 may be performed to further obtain a behavior of the user within the time t and determine whether the user is to open the inner screen <NUM> for browsing.

It may be understood that, that the posture of the foldable body <NUM> is in the non-horizontal state may be used as a preset condition for determining whether the foldable body <NUM> is switched to the non-folded state.

Referring to <FIG> and <FIG>, in an embodiment, S200 may include the following step:
S202: Determine whether an absolute value of a roll angle of the foldable body <NUM> is greater than a first preset angle, where a rotation axis corresponding to the roll angle is parallel to a folding axis of the foldable body.

Referring to <FIG>, posture angles (Euler angles) may be used herein to represent the posture of the foldable body <NUM>. The posture angles are determined by a relationship between a coordinate system of the foldable body <NUM> and a geographical coordinate system. When the foldable body <NUM> is in the folded state, a Cartesian coordinate system (X, Y, Z) is defined by using a center of the plane on which the outer screen <NUM> is located as a circle center. The Euler angles are angles by which the foldable mobile phone <NUM> rotates about three axes of the coordinate system (X, Y, Z). The folding axis of the foldable body may be a rotation axis of a rotating shaft <NUM> connecting the first body <NUM> and the second body <NUM>. A Y axis is parallel to the rotation axis.

An angle by which the foldable body <NUM> rotates about an X axis is a pitch (Pitch) angle, an angle by which the foldable body <NUM> rotates about the Y axis is a roll (Roll) angle, and an angle by which the foldable body <NUM> rotates about a z axis is a yaw (Yaw) angle. The Euler angles include the pitch angle, the roll angle, and the yaw angle. The Euler angles may be calculated from acceleration components of the acceleration sensor in the foldable body <NUM> on the X axis, the Y axis, and the Z axis.

If the user needs to further browse the inner screen <NUM> after browsing the outer screen <NUM>, the user usually performs the following operations:
The user covers the surface of the outer screen <NUM> with the protective cover <NUM> by a left hand, and raises, by a right hand, ends that are of the first body <NUM> and the second body <NUM> and that are away from the rotating shaft <NUM>, so that the foldable body <NUM> rotates about the rotating shaft <NUM> from a right side to a left side shown in the figure, and therefore a thumb of the left hand presses end surfaces that are of the first body <NUM> and the second body <NUM> and that are away from the rotating shaft <NUM>. In this process, the pitch angle of the foldable body <NUM> changes little. The foldable mobile phone <NUM> rotates about the Y axis, in order words, the roll angle of the foldable body <NUM> changes.

If the absolute value of the roll angle of the foldable body <NUM> is greater than the first preset angle, it indicates that the user is probably preparing to unfold the inner screen <NUM>. Therefore, it may be considered that the user is to open the inner screen <NUM> next to continue browsing. To improve continuity between browsing the inner screen <NUM> and browsing the outer screen <NUM> by the user, in this case, S105 may be performed to delay invoking the screen locking function for the time t.

If the absolute value of the roll angle of the foldable body <NUM> is not greater than the first preset angle, it indicates that the foldable terminal <NUM> rotates about the folding axis by a relatively small angle or does not rotate. Therefore, it may be determined that the user probably is not to continue to browse the inner screen <NUM>. Therefore, S104 may be performed to invoke the screen locking function. In some embodiments, the first preset angle may be <NUM>°, <NUM>°, or <NUM>°.

Further, in an embodiment, before S202, the method may further include the following step:
S201: Determine whether an absolute value of the pitch angle of the foldable body <NUM> is less than a second preset angle, or whether a component value of the acceleration sensor in the foldable body <NUM> in a gravity direction is less than a preset threshold, where a rotation axis corresponding to the pitch angle is perpendicular to the rotation axis corresponding to the roll angle.

In this embodiment, the component of the acceleration sensor in the foldable body <NUM> in the gravity direction may be calculated by using the pitch angle of the foldable body <NUM>. Therefore, the posture of the foldable body <NUM> can be determined by using only one of two physical quantities: the pitch angle of the foldable body <NUM> and the component of the acceleration sensor in the foldable body <NUM> in the gravity direction.

If the foldable body <NUM> is vertically placed (the plane on which the outer screen <NUM> is located is perpendicular to the horizontal plane), acceleration values on the X axis, the Y axis, and the Z axis are respectively x=<NUM>, y=<NUM>, and z=<NUM>. Therefore, the pitch angle of the foldable body <NUM> is <NUM> degrees. When the foldable body <NUM> is horizontally placed, y=<NUM>, and the pitch angle is <NUM> degrees. In a process in which the foldable body <NUM> is converted from being horizontally placed to being vertically placed, an acceleration value of the acceleration sensor on the y axis increases from <NUM> to <NUM>, and the pitch angle of the foldable body <NUM> increases from <NUM> degrees to <NUM> degrees or minus <NUM> degrees (when the user lies down and views the mobile phone, the outer screen <NUM> faces downward, and the pitch angle is negative in this case).

If the absolute value of the pitch angle is not less than the second preset angle, it indicates that in this case, the posture of the foldable terminal is nearly perpendicular to the horizontal plane, a two-dimensional projection amount, on the horizontal plane, of an X axis and a Z axis of a gravitational acceleration is relatively small. A relatively small fluctuation leads to a relatively large error in calculating the roll angle. If the absolute value of the pitch angle of the foldable body <NUM> is not less than the second preset angle, or the component of the acceleration sensor in the foldable body <NUM> in the gravity direction is not less than the preset threshold, the calculated roll angle cannot accurately reflect the posture of the foldable terminal. In this case, to prevent user experience from being affected because the foldable mobile phone <NUM> enters the screen locked state due to incorrect determining, S105 may be directly performed to delay invoking the screen locking function for the time t.

If the absolute value of the pitch angle of the foldable body <NUM> is less than the second preset angle, or the component of the acceleration sensor in the foldable body <NUM> in the gravity direction is less than the preset threshold, it indicates that the roll angle obtained in this case can relatively accurately reflect the posture of the foldable body <NUM>. Therefore, S112 may be performed to determine an intention of the user from the posture of the foldable body <NUM>, to determine whether to delay invoking the screen locking function for the time t.

In an embodiment, the second preset angle may be <NUM> degrees or a value close to <NUM> degrees, for example, <NUM> degrees, <NUM> degrees, <NUM> degrees, <NUM> degrees, or <NUM> degrees. For the component of the acceleration sensor in the gravity direction, the preset threshold may be <NUM> or a value close to <NUM>, for example, a value less than <NUM> or a value greater than <NUM>.

Referring to <FIG> and <FIG>, in an embodiment, if it is determined, in S201, that the absolute value of the pitch angle of the foldable body <NUM> is not less than the second preset angle, or the component value of the acceleration sensor in the foldable body <NUM> in the gravity direction is not less than the preset threshold, the following step is performed:
S105: Control the foldable mobile phone <NUM> to enter a small-window mode, but skip invoking the screen unlocking function.

In this embodiment, when it is determined that the absolute value of the pitch angle is not less than the second preset angle, or the component value of the acceleration sensor in the gravity direction is not less than the preset threshold, it indicates that in this case, the posture of the foldable body <NUM> cannot be accurately determined, in other words, a next intention of the user cannot be accurately determined. In this case, the user may not further unfold the inner screen <NUM> to continue browsing. Therefore, the small-window mode in the flip cover mode may be enabled. If the user indeed does not open the inner screen <NUM> to continue browsing, the user may further quickly browse information such as time and a short messaging service message through a small window of the outer screen <NUM>, so that browsing continuity experience of the user is improved. However, if the foldable mobile phone <NUM> completely enters the flip cover mode, in other words, the foldable mobile phone <NUM> enters the screen locked state while entering the small-window mode, the user needs to perform an unlocking operation if the user needs to unfold the inner screen <NUM> next for browsing. This affects browsing continuity of the user. Therefore, in this case, the screen locking function is not invoked when the small-window mode is enabled, and step S120 is performed to determine whether the user switches the foldable body <NUM> from the folded state to the non-folded state.

In this embodiment, if it is determined that the foldable body <NUM> is switched from the folded state to the non-folded state, it indicates that the user switches from the outer screen <NUM> to the inner screen <NUM> to continue browsing, and in this case, the screen locking function does not need to be re-invoked. Therefore, the foldable mobile phone <NUM> may be controlled to exit the small-window mode. In this case, the outer screen <NUM> may be powered off and be in a screen-off state, to save power.

If it is determined, in S202, whether the absolute value of the roll angle of the foldable body <NUM> is greater than the first preset angle, S105 may also be directly performed to prevent browsing experience of the user from being affected due to incorrect determining.

An embodiment of this application further provides an electronic device display method. An electronic device includes a foldable body <NUM>, an outer screen <NUM>, and an inner screen <NUM>. The outer screen <NUM> and the inner screen <NUM> are respectively located on two opposite surfaces of the foldable body. When the foldable body is in a folded state, and the outer screen <NUM> displays a non-lock screen, the method includes:.

When the outer screen <NUM> displays the non-lock screen, it indicates that a user is browsing content through the outer screen <NUM>. In this case, if it is sensed that the protective cover <NUM> approaches the outer screen <NUM> and reaches the preset position with respect to the outer screen <NUM>, it indicates that the user covers a surface of the outer screen <NUM> with the protective cover <NUM>. If it is determined that the foldable body is switched to the non-folded state within a preset time, it indicates that the user opens the inner screen <NUM> to continue browsing, and in this case, the inner screen <NUM> may be controlled to synchronously display the non-lock screen. Therefore, the user may directly browse, through the inner screen <NUM>, the interface just displayed on the outer screen <NUM>, so that browsing continuity of the user is improved.

The preset condition may include at least the preset time, and the preset time may be a period of time after the protective cover <NUM> approaches the outer screen <NUM> and reaches the preset position with respect to the first screen body.

It may be understood that, that the inner screen continues to display the non-lock screen may mean that after the inner screen is opened, progress of content displayed on the inner screen is slightly ahead of progress of content displayed when the outer screen is closed, to help the user memorize the content before the outer screen is closed, thereby improving browsing experience. In some embodiments, after the inner screen is opened, progress of content displayed on the inner screen may alternatively be exactly consistent with progress of content displayed before the outer screen is closed.

In an embodiment, the non-lock screen displayed on the first screen body may include a picture, a webpage, and the like. When switching to the second screen body is performed, the second screen body may display the same picture and the same webpage. When the non-lock screen displayed on the first screen body is a video, and switching to the second screen body is performed, play may be continued from the video displayed on the first screen body.

It should be noted that the foldable mobile phone <NUM> is merely an embodiment provided to explain and describe the method provided in this application. Another electronic device that has a same or similar function may also be applied to the foregoing embodiments.

An embodiment of this application further provides an electronic device. The electronic device may include a foldable body <NUM>, an inner screen <NUM>, an outer screen <NUM>, and a processor <NUM>. The inner screen <NUM> and the outer screen <NUM> are respectively located on two opposite surfaces of the foldable body <NUM>.

The foldable body <NUM> may include a protective cover <NUM> configured to cover the outer screen <NUM>. The processor is configured to: determine, when the foldable body <NUM> is in the folded state, that the protective cover <NUM> approaches the outer screen <NUM> and reaches a preset position with respect to the outer screen <NUM>, and then control the inner screen <NUM> to be in a screen non-locked state after determining, within a preset time, that the foldable body <NUM> is in a non-folded state.

In some embodiments, the electronic device may further include an acceleration sensor and a Hall effect sensor. The Hall effect sensor <NUM>, the inner screen <NUM>, the outer screen <NUM>, and the acceleration sensor <NUM> are separately connected to the processor. The Hall effect sensor <NUM> may be configured to detect whether the protective cover <NUM> approaches the outer screen <NUM> and reaches the preset position with respect to the outer screen <NUM>. The acceleration sensor <NUM> may be configured to sense acceleration components of the foldable body <NUM> in different directions. A posture of the foldable body <NUM> can be calculated based on the acceleration components. The processor may pre-determine a behavior of a user based on data sent by the acceleration sensor <NUM> and the Hall effect sensor <NUM>, then control display statuses of the inner screen <NUM> and the outer screen <NUM>, and control the foldable mobile phone <NUM> whether to enter a screen locked state.

An embodiment of this application further provides an electronic device. The electronic device includes a foldable body <NUM>, an inner screen <NUM>, an outer screen <NUM>, and a processor. The inner screen <NUM> and the outer screen <NUM> are respectively located on two opposite surfaces of the foldable body. The processor is configured to store a memory of executable instructions of the processor. When the processor is configured to execute the instructions, the electronic device is enabled to implement the method in the foregoing embodiments.

Based on such an understanding, the technical solutions in embodiments of this application essentially, or the part contributing to the conventional technology, or all or some of the technical solutions may be implemented in a form of a software product, for example, a program. The software product is stored in a program product, for example, a computer-readable storage medium, including several instructions used to enable a device (which may be a single-chip microcomputer, a chip, or the like) or a processor (processor) to perform all or some of the steps of the methods in embodiments of this application.
