The application framework layer is a framework of the application, and a developer can develop some applications based on the application framework layer under the condition of complying with the development principle of the framework of the application.

The system runtime layer includes libraries (also called system libraries) and android operating system runtime environments. The library mainly provides various resources required by the android operating system. The android operating system running environment is used for providing a software environment for the android operating system.

The kernel layer is an operating system layer of an android operating system and belongs to the bottommost layer of an android operating system software layer. The kernel layer provides kernel system services and hardware-related drivers for the android operating system based on the Linux kernel.

Taking an android operating system as an example, in the embodiment of the present invention, a developer may develop a software program for implementing the screen unlocking method provided in the embodiment of the present invention based on the system architecture of the android operating system shown in fig. 1, so that the screen unlocking method may operate based on the android operating system shown in fig. 1. Namely, the processor or the terminal can implement the screen unlocking method provided by the embodiment of the invention by running the software program in the android operating system.

The terminal in the embodiment of the invention can be a mobile terminal or a non-mobile terminal. For example, the mobile terminal may be a mobile phone, a tablet computer, a notebook computer, a palm top computer, a vehicle-mounted terminal, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a Personal Digital Assistant (PDA), and the like, and the non-mobile terminal may be a Personal Computer (PC), a Television (TV), a teller machine or a self-service machine, and the like, and the embodiment of the present invention is not particularly limited.

It should be noted that an execution main body of the screen unlocking method provided in the embodiment of the present invention may be a terminal, and may also be a functional module and/or a functional entity capable of implementing the screen unlocking method in the terminal, which may be specifically determined according to actual use requirements, and the embodiment of the present invention is not limited. The screen unlocking method provided by the embodiment of the invention will be exemplarily described below by taking the execution subject of the screen unlocking method as an example.

As shown in fig. 2, an embodiment of the present invention provides a screen unlocking method. The method may be applied to a terminal including a first screen and a second screen. The method may include steps 100-103 described below.

Step 100, the terminal acquires a first image acquired by a camera of a first screen.

Optionally, the terminal in the embodiment of the present invention may be a folding screen terminal. The folding screen terminal can comprise a first screen and a second screen, and a camera can be arranged on the first screen.

Illustratively, as shown in fig. 3 (a), the first screen 01 and the second screen 02 may be two separate screens, the first screen 01 and the second screen 02 are connected by a shaft 03 (or a hinge), and the first screen 01 is provided with a camera 04. As shown in (b) of fig. 3, the screen of the terminal may be a single screen (e.g., a flexible screen), and when a user performs a folding operation on the flexible screen, the flexible screen may be folded into two different screens (i.e., a first screen 01 and a second screen 02), and the first screen 01 is provided with a camera 04.

Further, in the embodiment of the present invention, in a case that the screen of the terminal is two independent screens, the first screen and the second screen may be any one of the following displays: liquid Crystal Display (LCD), Plasma Display (PDP), Thin Film Transistor (TFT) -LCD, Organic Light Emitting Diode (OLED) and active matrix (AM-OLED). The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

Further, in the embodiment of the present invention, in a case that the screen of the terminal is a single screen (for example, a flexible screen), when the user performs a folding operation on the flexible screen, if a position or a direction at which the flexible screen is folded is different, the first screen and the second screen that are folded out of the flexible screen are different. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

Further, in the embodiment of the present invention, a camera may be disposed on the second screen.

Optionally, in the embodiment of the present invention, when the camera of the first screen acquires the first image, the first screen may be in a screen locking state or an unlocking state. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

Further, in the embodiment of the present invention, the screen locking state may be a screen locking and turning-on state or a screen turning-off state. The screen locking and lightening state means that after the screen of the terminal is locked, the backlight module of the terminal is in a lightening state, namely the terminal is in the screen locking and lightening state; the screen-off state refers to a state that the backlight module of the terminal is closed after the screen of the terminal is locked, that is, the terminal is in a state that the screen is locked and the backlight module is closed.

It should be noted that the screen in the embodiment of the present invention may include a display, a frame disposed around the display, and a camera disposed on the frame. For example, the first screen may include a display, a bezel, and a camera disposed on the bezel, and the second screen may include a display and a bezel. It is understood that the screen locking state and the screen unlocking state in the embodiment of the present invention both refer to the state of the display in the screen, and not the state of the border in the screen.

Step 101, the terminal judges whether the first image is matched with a second image displayed by a second screen.

For specific descriptions of the first screen and the second screen, reference may be made to the description of the first screen and the second screen in step 100 of the foregoing embodiment, and details are not repeated here.

In the embodiment of the invention, the terminal can judge whether the first image is matched with the second image displayed by the second screen. In the case that the first image matches the second image displayed on the second screen, the terminal may proceed to step 102 described below; in case the first image does not match the second image displayed by the second screen, the terminal may proceed to step 103 described below.

It should be noted that, in the embodiment of the present invention, the "matching" may be understood as that the similarity between two compared objects is greater than or equal to a numerical value. For example, when the similarity between the first image and the second image is greater than or equal to a preset value (for example, the preset value may be 90%), it may be determined that the first image matches the second image.

Optionally, in this embodiment of the present invention, the second image displayed on the second screen may be a preset image (for example, an image in a gallery of the terminal), or may be an image displayed on the second screen according to a track input by the user on the second screen. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

And 102, unlocking the target screen by the terminal.

Wherein the target screen may include at least one of a first screen and a second screen.

In the embodiment of the invention, the terminal can unlock the target screen under the condition that the first image is matched with the second image displayed by the second screen. For example, the terminal may unlock the first screen, or unlock the second screen, or unlock both the first screen and the second screen. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

Optionally, in the embodiment of the present invention, before the terminal unlocks the target screen, the terminal may determine the target screen to be unlocked. Specifically, the terminal may determine the target screen in any one of the following manners:

in the first mode, the terminal can determine the target screen according to the screen state of the first screen and the screen state of the second screen. For example, in a case where the screen state of the first screen and the screen state of the second screen are both the screen-locked state, the terminal may determine that the target screen is the first screen and the second screen.

And in the second mode, the terminal can determine the target screen according to the included angle between the first screen and the second screen. For example, the terminal may determine a target screen (at least one of the first screen and the second screen) in a case where an angle between the first screen and the second screen belongs to a preset angle range.

And thirdly, the terminal can determine the target screen according to the preset of the user. For example, the user may designate the target screen as the first screen, or the second screen, or both the first screen and the second screen in advance.

It should be noted that, in the embodiment of the present invention, for a specific implementation manner of the first manner, step 106a and step 106b in the following embodiment are described, and details are not described here. For the specific implementation of the second mode, step 107a and step 107b in the following embodiments will be described, which are not repeated herein.

And 103, displaying prompt information by the terminal.

For example, in the case that the first image does not match the second image displayed on the second screen, the terminal may not unlock the first screen and/or the second screen in the screen-locked state, and display a prompt message "unlock failure, please unlock again".

It should be noted that, the step 103 is an optional implementation manner provided in the embodiment of the present invention, that is, in a case that the first image does not match the second image displayed on the second screen, the terminal may display a prompt message. It can be understood that, in the case that the first image does not match the second image displayed on the second screen, the terminal may not perform any operation, or the terminal may further retrieve the first image captured by the camera of the first screen and determine whether the first image matches the second image displayed on the second screen. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

The embodiment of the invention provides a screen unlocking method which can be applied to a terminal comprising a first screen and a second screen. Under the condition that a first image acquired by a camera of the first screen is matched with a second image displayed by the second screen, the terminal can unlock at least one of the first screen and the second screen, so that automatic unlocking of the terminal can be realized, and information (such as passwords, fingerprints or patterns and the like) for controlling the terminal to unlock the screen does not need to be manually input by a user, so that the flexibility of unlocking the screen by the terminal is improved.

Optionally, with reference to fig. 2, as shown in fig. 4, in the embodiment of the present invention, before step 100, the screen unlocking method provided in the embodiment of the present invention may further include step 104 described below.

And 104, the terminal acquires a second image and displays the second image on a second screen.

Optionally, in the embodiment of the present invention, when the terminal acquires the second image and displays the second image on the second screen, the second screen may be in a screen-locked and screen-lightened state, or in an unlocked state. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

Optionally, in an embodiment of the present invention, in a first possible implementation manner, when the second image is a preset image, the step 104 may be specifically implemented by the following step 104 a; in a second possible implementation manner, in the case that the second image is an image displayed on the second screen according to the track input of the user on the second screen, the step 104 can be implemented by the following steps 104b to 104 d.

For a first possible implementation:

and 104a, the terminal acquires a preset second image and displays the second image on a second screen.

It should be noted that, in the case that the second image is a preset image, the embodiment of the present invention does not specifically limit the pattern, the shape, the size, the color, the display area, and the like of the second image, and may specifically be determined according to the actual use requirement. For example, the second image may be a yellow five-pointed star, may be a black character "pi", may be a person image composed of a plurality of colors, or the like.

Optionally, in the embodiment of the present invention, when the second image is a preset image, the second image may be an image in a gallery of the terminal.

Exemplarily, fig. 5 is a schematic diagram of a terminal displaying a second image according to an embodiment of the present invention. Assuming that the first screen 01 and the second screen 02 of the terminal are two independent screens, and the camera 04 is disposed on the first screen 01, the terminal may obtain a second image 05 from a gallery of the terminal and display the second image 05 on the second screen 02, as shown in fig. 5. Then, the terminal may control the camera 04 to capture the second image 05 to obtain the first image, and unlock the target screen (i.e., at least one of the first screen 01 and the second screen 02) if the first image matches the second image 05.

It can be understood that, for the first possible implementation manner, since the second image may be a preset image, the terminal may directly display the second image on the second screen of the terminal without the need of the user to select an image or draw an image, thereby simplifying the operation steps of the user and improving the convenience of displaying the second image by the terminal. Furthermore, the terminal can directly display the second image on the second screen of the terminal, so that the terminal can obtain the first image according to the second image and match the second image with the first image to unlock the screen, and a user does not need to manually input information (such as a password, a fingerprint or a pattern and the like) for controlling the terminal to unlock the screen, thereby improving the flexibility of unlocking the screen by the terminal.

For a second possible implementation:

and 104b, receiving the track input of the user on the second screen by the terminal.

And 104c, responding to the track input by the terminal, and displaying a pattern generated by the track input on the second screen.

And 104d, generating a second image based on the pattern by the terminal and displaying the second image on the second screen.

Optionally, in the embodiment of the present invention, the terminal may display the second image on the second screen according to a preset color, or may display the second image on the second screen according to a color selected by the user. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

For example, fig. 6 is a schematic diagram of another terminal displaying a second image according to an embodiment of the present invention. Assuming that the first screen 01 and the second screen 02 of the terminal are two separate screens and the camera 04 is disposed on the first screen 01, as shown in fig. 6, the user may perform a sliding operation on the second screen 02, and then the terminal may receive a trace input by the user on the second screen 02 (i.e., the user may draw a pattern on the second screen 02), and in response to the trace input, display a pattern generated by the trace input on the second screen 02, and based on the pattern, generate and display a second image 05 on the second screen 02. Then, the terminal may control the camera 04 to capture the second image 05 to obtain a first image, and unlock a target screen (i.e., at least one of the first screen 01 and the second screen 02) in a case where the first image matches the second image 05 displayed on the second screen 02.

It can be understood that, for the second possible implementation manner, the second image may be an image generated according to the trajectory input of the user, so that the user may trigger the terminal to generate different second images according to actual requirements, so that the diversity and flexibility of displaying the second image by the terminal may be improved, and the experience of the user may be improved. Furthermore, when the second image generated by the user triggering the terminal is different, the first image acquired by the terminal may be different, so that the diversity and flexibility of the terminal unlocking screen can be improved, and the security of the terminal unlocking screen can also be improved.

According to the screen unlocking method provided by the embodiment of the invention, the terminal can acquire the second image and display the second image on the second screen, so that the terminal can acquire the first image according to the second image and match the second image with the first image to unlock the screen, and the user does not need to manually input information (such as a password, a fingerprint or a pattern and the like) for controlling the terminal to unlock the screen, so that the flexibility of unlocking the screen by the terminal is improved.

Further, for the second possible implementation manner, before the step 104d, the screen unlocking method provided in the embodiment of the present invention may further include the following steps 104e and 104 f. In this case, the step 101 may be specifically a step 101a and a step 101b described below.

And step 104e, the terminal acquires the first biological characteristic information of the user.

And step 104f, under the condition that the first biological characteristic information is matched with the preset biological characteristic information, the terminal updates the pattern to be in a preset color.

Optionally, in this embodiment of the present invention, the first biometric information may be at least one of facial feature information, iris feature information, retina feature information, fingerprint feature information, hand shape feature information, and the like of the user. Correspondingly, in the embodiment of the invention, the terminal can acquire the target biological characteristic information of the user through a biological characteristic identification technology. The biometric technology in the embodiment of the present invention may be at least one of a facial recognition technology, an iris recognition technology, a retina recognition technology, a fingerprint recognition technology, a palm geometry recognition technology, and the like.

For example, the description will be given taking biometric information as facial feature information. The specific way for the terminal to obtain the biometric information of the user may be: the terminal can take a picture through the camera on the first screen. If the user is located within the shooting range of the camera, the terminal can shoot pictures through the camera, detects the portrait of the user from at least one shot picture, and separates the portrait of the user from the background. Then, the terminal may obtain facial feature information of the user from the separated portrait according to a preset facial recognition algorithm, determine whether the facial feature information matches with preset facial feature information, and update the pattern to a preset color by the terminal in a case that the facial feature information matches with the preset facial feature information.

Step 101a, the terminal judges whether the object characteristics of the first object and the object characteristics of the second object are matched.

And step 101b, under the condition that the object characteristics of the first object are matched with the object characteristics of the second object, the terminal judges whether the color of the first object and the color of the second object are both preset colors.

Wherein the object feature may include at least one of: shape, area, and feature points.

For specific descriptions of the shape, the area and the feature point, reference may be made to the description of the shape, the area and the feature point in step 101c of the following embodiments, which is not repeated herein. In this embodiment of the present invention, the terminal may determine whether the object feature of the first object and the object feature of the second object match (e.g., determine whether the shape of the first object and the shape of the second object match, or determine whether the feature point of the first object and the feature point of the second object match). In the case that the object feature of the first object and the object feature of the second object match, the terminal may determine whether the color of the first object and the color of the second object are both preset colors. Therefore, the terminal can unlock the target screen under the condition that the object characteristics of the first object are matched with the object characteristics of the second object, and the color of the first object and the color of the second object are both preset colors.

It should be noted that, in the embodiment of the present invention, the terminal performs step 101a first and then performs step 101b for exemplary illustration, which does not limit the embodiment of the present invention at all. It can be understood that, in actual implementation, the terminal may also perform step 101b first and then perform step 101a (i.e., the terminal determines whether the color of the first object and the color of the second object are both the preset colors, and then determines whether the object feature of the first object and the object feature of the second object are matched); alternatively, the terminal may also perform step 101a and step 101b at the same time (i.e., the terminal determines whether the color of the first object and the color of the second object are both the preset colors and whether the object feature of the first object and the object feature of the second object match at the same time).

According to the screen unlocking method provided by the embodiment of the invention, under the condition that the acquired first biological characteristic information is matched with the preset biological characteristic information, the terminal can update the pattern generated according to the track input into the preset color (namely, the terminal can display the second image according to the preset color), so that the terminal can unlock the target screen under the condition that the object characteristics of the first object are matched with the object characteristics of the second object and the color of the first object and the color of the second object are both the preset colors, and therefore, the safety of the terminal in unlocking the target screen is improved.

Optionally, with reference to fig. 2, as shown in fig. 7, in the embodiment of the present invention, before the step 100, the screen unlocking method provided in the embodiment of the present invention may further include the following step 105a and step 105 b.

And 105a, the terminal detects the size of an included angle between the first screen and the second screen.

And 105b, under the condition that the detected included angle is within the preset included angle range, the terminal controls the camera of the first screen to acquire a first image.

It should be noted that, in the embodiment of the present invention, when the terminal controls the camera of the first screen to acquire the first image, the camera of the first screen may be in an open state or in a closed state. For example, if the camera of the first screen is in an on state, the terminal may directly control the camera of the first screen to acquire the first image; if the camera of the first screen is in a closed state, the terminal can start the camera of the first screen and control the camera of the first screen to acquire a first image. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

For example, in the case that the screen of the terminal is two independent screens, or the screen of the terminal is one screen, the user may perform a folding operation on the screens to change an included angle between the first screen and the second screen. Under the condition that the included angle detected by the terminal is within a preset included angle range (for example, the preset included angle range can be 30-180 degrees, 100-130 degrees or 50-80 degrees), the terminal can control the camera of the first screen to acquire a first image; and under the condition that the included angle detected by the terminal is within the range of the preset included angle, the terminal can acquire images without controlling a camera of the first screen. The method can be determined according to actual use requirements, and the embodiment of the invention is not limited.

According to the screen unlocking method provided by the embodiment of the invention, the size of the included angle between the first screen and the second screen can be obtained, and the terminal controls the camera of the first screen to acquire the first image under the condition that the included angle is within the range of the preset included angle, so that the time for opening the camera by the terminal can be controlled by setting the preset included angle, and the camera of the first screen is controlled to acquire the first image under the condition that the included angle between the first screen and the second screen is in any size, so that the power consumption of the terminal can be reduced, and the unlocking safety of the terminal can be improved.

Optionally, with reference to fig. 2, as shown in fig. 8, in the embodiment of the present invention, before the step 102, the screen unlocking method provided in the embodiment of the present invention may further include the following step 106a and step 106 b.

And 106a, the terminal acquires the screen state of the first screen and the screen state of the second screen.

And 106b, the terminal determines a target screen according to the screen state of the first screen and the screen state of the second screen.

The screen state may include a screen lock state and an unlock state.

For specific description of the target screen, reference may be made to the related description of the target screen in step 102 of the foregoing embodiment, and details are not described here again.

For example, in the case that the screen state of the first screen and the screen state of the second screen are both the screen-locking state, the terminal may determine that the target screen is the first screen and the second screen; under the condition that the screen state of the first screen is the screen locking state and the screen state of the second screen is the unlocking state, the terminal can determine that the target screen is the first screen; under the condition that the screen state of the second screen is the screen locking state and the screen state of the first screen is the unlocking state, the terminal can determine that the target screen is the second screen.

According to the screen unlocking method provided by the embodiment of the invention, the target screen can be determined according to the screen state of the first screen and the screen state of the second screen by acquiring the screen state of the first screen and the screen state of the second screen. Therefore, when the screen state of the first screen is different from the screen state of the second screen, the target screen determined by the terminal is different, and the mode of unlocking the screen by the terminal is different, so that the diversity of unlocking the screen by the terminal can be improved, and the safety of unlocking the screen by the terminal can also be improved.

Optionally, with reference to fig. 2, as shown in fig. 9, in the embodiment of the present invention, before the step 102, the screen unlocking method provided in the embodiment of the present invention may further include the following step 107a and step 107 b.

Step 107a, the terminal acquires a first included angle between the first screen and the second screen.

And step 107b, the terminal determines the target screen according to the included angle range to which the first included angle belongs.

Optionally, in the embodiment of the present invention, an included angle between the first screen and the second screen may be adjustable.

For example, in the case that the included angle range to which the first included angle belongs is a first target included angle range, the terminal may determine that the target screen is a first screen and a second screen; under the condition that the included angle range to which the first included angle belongs is a second target included angle range, the terminal can determine that the target screen is the first screen; and under the condition that the included angle range to which the first included angle belongs is a third target included angle range, the terminal can determine that the target screen is the second screen. The first target included angle range, the second target included angle range, and the third target included angle range may be different included angle ranges (for example, the first included angle range may be 120 ° to 180 °, the second included angle range may be 60 ° to 90 °, and the third included angle range may be 90 ° to 120 °).

According to the screen unlocking method provided by the embodiment of the invention, the target screen can be determined according to the included angle range of the included angle by acquiring the included angle between the first screen and the second screen. Therefore, when the included angle ranges of the included angles of the first screen and the second screen are different, the target screens determined by the terminal are different, and the screen unlocking mode of the terminal is different, so that the diversity of the screen unlocking of the terminal can be improved, and the experience of a user can be improved.

Optionally, in the embodiment of the present invention, before the step 101, the screen unlocking method provided in the embodiment of the present invention may further include the following step 108a and step 108 b. In this case, step 101 can be specifically realized by step 101c described below.

And 108a, the terminal acquires the object characteristics of the first object in the first image.

Wherein the object characteristics of the first object may comprise at least one of: shape, color, area, and feature points.

And 108b, the terminal acquires the object characteristics of the second object in the second image.

Wherein the object characteristics of the second object may comprise at least one of: shape, color, area, and feature points.

Step 101c, the terminal determines whether the object feature of the first object and the object feature of the second object match.

In the embodiment of the invention, the terminal can judge whether the object characteristics of the first object are matched with the object characteristics of the second object. In case the object feature of the first object and the object feature of the second object match, the terminal may perform step 102 described above (i.e., in case the object feature of the first object and the object feature of the second object match, the terminal may unlock the target screen); in case the object feature of the first image and the object feature of the second object do not match, the terminal may perform step 103 described above (i.e., in case the object feature of the first image and the object feature of the second object do not match, the terminal may display a prompt message).

For example, in the case where the object feature is a color, the terminal may acquire the color of the first object in the first image and acquire the color of the second object in the second image. If the color of the first object is yellow and the color of the second object is yellow, the terminal may determine that the color of the first object and the color of the second object match and unlock the target screen.

For example, in the case where the object features are an area and a color, the terminal may determine whether the color of the first image and the color of the second image match; in the case where it is determined that the color of the first image and the color of the second image match, the terminal may determine a first region having the first color in the first image and a second region having the first color in the second image; thereafter, the terminal may acquire the area of the first region and the area of the second region. If the area of the first region and the area of the second region are equal, the terminal may determine that the area of the first region and the area of the second region match and unlock the target screen.

For example, in the case that the object feature is a shape, the terminal may perform edge detection on a first object in the first image to determine an edge point of the first object, and perform edge detection on a second object in the second image to determine an edge point of the second object; then, the terminal may perform distance transformation on the edge point of the first object to obtain a distance mapping image of the first object, and perform distance transformation on the edge point of the second object to obtain a distance mapping image of the second object; if the target distance of the distance map image of the first object and the target distance of the distance map image of the second object are less than or equal to a preset threshold, the terminal may determine that the shape of the first object and the shape of the second object match and unlock the target screen.

For example, in the case where the object feature is a feature point, the terminal may acquire at least one feature point (referred to as a first feature point) of a first object in the first image and at least one feature point (referred to as a second feature point) of a second object in the second image. Then, the terminal may determine the position of the first object in the first image according to the first feature point and determine the position of the second object in the second image according to the second feature point. If the position of the first object in the first image corresponds to the position of the second object in the second image, the terminal may determine that the feature point of the first object matches the feature point of the second object and unlock the target screen.

The screen unlocking method provided by the embodiment of the invention can acquire the object characteristics of the first object in the first image and the object characteristics of the second object in the second image, and unlock the target screen under the condition that the object characteristics of the first object and the object characteristics of the second object are matched, so that the accuracy and flexibility of unlocking the screen by the terminal can be improved.

Optionally, in the embodiment of the present invention, before the step 100, the screen unlocking method provided in the embodiment of the present invention may further include the following step 109a and step 109 b.

And step 109a, under the condition that the second screen is in the screen-off state, the terminal receives a first input of a user.

Step 109b, the terminal responds to the first input and lights up the second screen.

The first input may be used to trigger the terminal to light a second screen of the terminal.

For specific description of the screen-off state, reference may be made to the description of the screen-off state in the foregoing embodiments, and details are not described here.

Optionally, in an embodiment of the present invention, the first input may be a key input. For example, the key input may be a single-click input, a double-click input, a long-press input, or a combined key input of a terminal key (e.g., a volume key, a power key, a host key, or the like) by a user, which may be determined according to actual usage requirements, and the embodiment of the present invention is not limited.

According to the screen unlocking method provided by the embodiment of the invention, the terminal can respond to the received first input of the user and light the second screen of the terminal, so that the terminal can display the second image on the second screen, or the terminal can respond to the track input of the user and display the second image on the second screen and further unlock the target screen (namely at least one of the first screen and the second screen), thereby improving the flexibility of the terminal in unlocking the screen.
