[0002] Currently, in under-display fingerprint recognition, the fingerprint recognition module is fixed in a designated area under the screen, and the effective area (AA) corresponding to the visible area (FOV, Field of View) above the screen is also relatively fixed. When users enroll their fingerprints and unlock the device, they need to press on the designated effective area to recognize the fingerprint. Moreover, this effective area is generally smaller than the fingerprint area of ​​the fingertip. When users enroll their fingerprints, they often need to move their fingertip multiple times so that the fingerprint recognition module can collect enough fingerprints. Summary of the Invention

[0027] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and do not limit this application. Attached Figure Description

[0037] Figure 8 This is a block diagram of a terminal according to an exemplary embodiment. Detailed Implementation

[0038] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and mounting components consistent with some aspects of the invention as detailed in the appended claims.

[0039] In related technologies, the fingerprint recognition module is fixed in a designated area, and the effective area for fingerprint recognition (see reference) Figure 1' The area shown in 20' is the area corresponding to the sensor (reference). Figure 1' The area shown in 10' is fixed, with a small area and its position cannot be changed. When a user enrolls their fingerprint, the entire fingertip needs to be captured, requiring the user to move their finger multiple times to meet the fingerprint enrollment requirements. When unlocking, the user's finger cannot be accurately positioned in the effective fingerprint recognition area, resulting in a low fingerprint recognition success rate.

[0040] This disclosure provides a sensor mounting assembly for use in a terminal (e.g., a mobile phone). In this mounting assembly, the position of the sensor can be adjusted in a first direction via a first adjusting component, and the position of the sensor can be adjusted in a second direction via a second adjusting component.

[0041] For example, when a sensor is used to collect fingerprint information applied to a display screen, the effective area for fingerprint recognition is no longer limited to the fixed area corresponding to the sensor (see reference). Figure 1 The region shown in 10a, and Figure 2 The area shown in 10b expands the effective area for fingerprint recognition (see reference). Figure 1 The area shown in 20a, and Figure 2 The area shown in 20b facilitates fingerprint collection and recognition, speeds up fingerprint enrollment and unlocking, enables fingerprint recognition at any location on the screen, and enhances the user experience.

[0042] In one exemplary embodiment, a sensor mounting assembly is provided. (Reference) Figure 3-5 As shown, the mounting assembly includes a mounting section 2, and a sensor 1 is mounted on the mounting section 2. The sensor 1 and the mounting assembly are mounted below the display screen 8 of the terminal.

[0043] Sensor 1 can be a fingerprint sensor, an image sensor, a voice recognition sensor, etc.

[0044] For example, sensor 1 is a fingerprint recognition sensor, which is used to collect fingerprint information applied to display screen 8 in order to realize the under-display fingerprint recognition function.

[0045] For example, sensor 1 is an image sensor, which is used to collect image information in front of the display screen 8 to realize the under-display camera function.

[0046] The role of the sensor does not affect the specific settings of the installation components. For ease of explanation, this disclosure will mainly use the sensor to collect fingerprint information applied to the display screen as an example to introduce the specific solution.

[0047] The mounting assembly may include a first adjustment component for adjusting the mounting part 2 in a first direction (see reference). Figure 1-2 as well as Figure 4-5 The position of the sensor 1 in the first direction is adjusted to avoid the fingerprint collection area being limited to a fixed area in the first direction.

[0048] The mounting assembly may also include a second adjustment assembly for adjusting the mounting part 2 in a second direction (see reference). Figure 1-2 as well as Figure 4-5 The position of sensor 1 in the second direction is adjusted to avoid the fingerprint collection area being limited to a fixed area in the second direction.

[0049] The mounting component can be equipped with both the first and second adjustment components, or only one of them. When both the first and second adjustment components are configured, the sensor 1 can be adjusted in both the first and second directions, which can better expand the effective area of ​​the display screen 8 for fingerprint collection, facilitate fingerprint collection and recognition, speed up fingerprint enrollment and unlocking, and enable fingerprint recognition at any position on the screen.

[0050] In addition, the first direction and the second direction can be perpendicular. As shown in the figure, the first direction is the width direction of the display screen 8 and the second direction is the length direction of the display screen 8, so as to adjust the position of the sensor 1 in the length and width directions, thereby making it easier to adjust the position of the sensor 1, enabling faster fingerprint enrollment and fingerprint unlocking, and improving the user experience.

[0051] In terminals equipped with this installation component, the position of the sensor 1 used for fingerprint collection is adjustable, and the effective area for fingerprint recognition is no longer limited to a fixed area. This expands the area of ​​the effective fingerprint recognition area, making it easier to collect and recognize fingerprints. It can speed up fingerprint enrollment and unlocking, and enable fingerprint recognition at any position on the screen, thus improving the user experience.

[0052] It should be noted that in terminals equipped with this installation component, the effective area for fingerprint recognition is related to the adjustable range of the first and second adjustment components within the installation component; the larger the adjustment range, the larger the effective area.

[0053] For example, the area of ​​the effective region can be as follows: Figure 1 The region shown in 20a can also be as follows: Figure 2 The area shown in 20b.

[0054] In one exemplary embodiment, a sensor mounting assembly is provided. (Reference) Figure 3-5 As shown, in this mounting assembly, the first adjustment component may include a first guide portion 31, wherein the first guide portion 31 may be a track extending along a first direction. When the first adjustment component adjusts the movement of the mounting portion 2, the first adjustment component may adjust the movement of the mounting portion 2 along the first guide portion 31, so that the first guide portion 31 guides the movement direction of the mounting portion 2 to ensure that the mounting portion 2 moves along the first direction.

[0055] Furthermore, in this mounting assembly, the second adjustment component may be similar to the first adjustment component. The second adjustment component may include a second guide portion 41, wherein the second guide portion 41 may be a track extending along a second direction. When the second adjustment component adjusts the movement of the mounting portion 2, the second adjustment component adjusts the movement of the mounting portion 2 along the second guide portion 41, such that the second guide portion 41 guides the movement direction of the mounting portion 2 to ensure that the mounting portion 2 moves along the second direction.

[0056] The mounting assembly may also include a first connecting part 5, and a first guide part 31 may be fixedly connected to the first connecting part 5.

[0057] The second adjustment component can adjust the movement of the second connecting part 6 along the second guide to drive the movement of the mounting part 2 along the second direction.

[0058] In this mounting assembly, the first connecting part 5 and the first guide part 31 are ensured to move along the second direction by the second guide part 41, thereby adjusting the position of the mounting part 2 in the second direction, and adjusting the position of the mounting part 2 in the first direction by the first guide part 31, thereby adjusting the position of the sensor 1. The effective area of ​​fingerprint recognition is no longer limited to a fixed area, thus expanding the area of ​​the effective area of ​​fingerprint recognition.

[0059] In one exemplary embodiment, a sensor mounting assembly is provided. (Reference) Figure 3-5 As shown, the mounting assembly may further include a magnetic element 9 (e.g., a permanent magnet), which is disposed on the mounting portion 2 and fixedly connected to it. The first adjustment assembly may further include a first detection coil 33 and a first control coil 32. In a first direction, the first detection coil 33 and the first control coil 32 are disposed opposite to each other, and the magnetic element 9 is located between the first detection coil 33 and the first control coil 32.

[0060] Specifically, by applying a first driving current to the first control coil 32, the magnetic field of the magnetic component 9 and the magnetic field of the first control coil 32 generate a magnetic force, thereby applying a driving force to the magnetic component 9, and then applying a driving force to the mounting part 2. Under the guidance of the first guide part 31, the mounting part 2 is driven to move along the first direction.

[0061] During the movement of the mounting part 2, since there is relative movement between the magnetic component 9 and the first detection coil 33, the first detection coil 33 can generate current. Based on the current of the first detection coil 33, the distance that the mounting part 2 moves along the first direction can be determined, thereby ensuring that the mounting part 2 moves to the target area (e.g., the area where the touch position is located) to achieve fingerprint collection.

[0062] Additionally, in this mounting assembly, the second adjustment component may also include a second detection coil 43 and a second control coil 42. In the second direction, the second detection coil 43 and the second control coil 42 are arranged opposite to each other, and the magnetic element 9 is located between the second detection coil 43 and the second control coil 42.

[0063] Specifically, by applying a first driving current to the second control coil 42, the magnetic field of the magnetic component 9 and the magnetic field of the second control coil 42 generate a magnetic force, thereby applying a driving force to the magnetic component 9, and then applying a driving force to the mounting part 2. Under the guidance of the second guide part 41, the mounting part 2 is driven to move in the second direction.

[0064] During the movement of the mounting part 2, since there is relative movement between the magnetic component 9 and the second detection coil 43, the second detection coil 43 can generate current. Based on the current of the second detection coil 43, the distance of the mounting part 2 along the second direction can be determined, thereby ensuring that the mounting part 2 moves to the target area (e.g., the area where the touch position is located) to achieve fingerprint collection.

[0065] In this mounting assembly, the magnetic element 9 can be ring-shaped and can be arranged around the sensor 1. The first detection coil 33, the first control coil 32, the second detection coil 43, and the second control coil 42 are arranged on the radial outer side of the magnetic element 9 to better drive the sensor 1 to move.

[0066] The first detection coil 33 and the first control coil 32 are fixedly connected to the first connecting part 5, that is, the first detection coil 33 and the second control coil 42 can be disposed in the first connecting part 5. This enables relative movement between the magnetic component 9 and the first control coil 32, that is, under the interaction force between the magnetic component 9 and the first control coil 32, the mounting part 2 moves along the first guide part 31. The mounting assembly may further include a second connecting portion 6, which can be fixedly connected to other structures of the terminal; that is, the entire mounting assembly is fixed to the terminal via the second connecting portion 6. The second guide portion 41, the second detection coil 43, and the second control coil 42 are respectively fixedly connected to the second connecting portion 6; that is, the second guide portion 41, the second detection coil 43, and the second control coil 42 can all be disposed on the second connecting portion 6. This enables relative movement between the magnetic element 9 and the second control coil 42; that is, under the interaction force between the magnetic element 9 and the second control coil 42, the mounting portion 2 moves along the second guide portion 41.

[0067] In addition, when the first connecting part 5 moves along the second direction, the first detection coil 33, the second detection coil 43, the magnetic component 9, the first guide part 31, the mounting part 2, and the sensor 1 all move along the second direction to ensure that the movement of the mounting part 2 along the second direction does not affect its movement along the first direction.

[0068] The mounting assembly may further include a control unit 7 (which may include control and detection circuitry), with the first detection coil 33, the second detection coil 43, the first control coil 32, and the second control coil 42 electrically connected to the control unit 7. In other words, in this mounting assembly, the control unit 7 controls the movement of the mounting part 2, thereby driving the sensor 1 to move to the target position.

[0069] It should be noted that the magnetic component 9, the first control coil 32, the first detection coil 33, the second control coil 42, and the second detection coil 43 can also be configured in other ways, as long as the magnetic component 9, the first control coil 32, the first detection coil 33, the second control coil 42, and the second detection coil 43 can work together to drive the sensor 1 to move and can detect whether the sensor 1 has moved to the touch position.

[0070] The mounting assembly uses a magnetic field to move the mounting part 2, adjusting the position of the sensor 1. This allows the effective area of ​​fingerprint recognition to be expanded, as the effective area of ​​fingerprint recognition is no longer limited to a fixed area.

[0071] In one exemplary embodiment, a sensor module is provided. (Reference) Figure 3 As shown, the sensor module includes a sensor 1 and the aforementioned mounting assembly, with the sensor 1 mounted on the mounting portion 2 of the mounting assembly. The sensor 1 module is mounted below the display screen 8 of the terminal.

[0072] For example, sensor 1 is used to collect fingerprint information applied to display screen 8 in order to realize the under-display fingerprint recognition function.

[0073] In terminals equipped with this sensor module, the position of sensor 1 used for fingerprint collection is adjustable. The effective area for fingerprint recognition is no longer limited to a fixed area, thus expanding the area of ​​the effective fingerprint recognition area. This facilitates fingerprint collection and recognition, speeds up fingerprint enrollment and unlocking, enables fingerprint recognition at any position on the screen, and improves the user experience.

[0074] For example, sensor 1 is used to collect image information in front of display screen 8 to realize the under-display camera function.

[0075] In terminals equipped with this sensor module, the position of sensor 1, used for collecting image information, is adjustable. The image acquisition area is no longer limited to a fixed area, expanding the effective area of ​​image acquisition. This facilitates image acquisition and facial recognition, speeds up facial registration, facial recognition, and image capture, and enhances the user experience.

[0076] In one exemplary embodiment, a fingerprint recognition method is provided, applied to a terminal, which may include the aforementioned sensor module, wherein the sensor of the sensor module is used to collect fingerprint information applied to the display screen.

[0077] refer to Figure 6 As shown, the method may include: S110, determine the target location information of the touch position based on the touch information; S120, Obtain the current position information of the mounting part of the sensor mounting assembly; S130, determine whether the region represented by the target location information matches the region represented by the current location information. If they match, proceed to step S140; if they do not match, proceed to step S150. S140, the mounting position remains unchanged while fingerprint information is collected.

[0078] S150: After the drive unit moves to the area represented by the target position information, fingerprint information is collected.

[0079] In step S110, when a user uses the terminal's fingerprint recognition function, the user needs to touch the display screen with their finger. Touch information is then acquired, and based on this touch information, the target location information of the touch area can be determined. The target location information represents the touch area; it can be the center location information of the touch area or the location information of the entire touch area.

[0080] In step S120, the sensor for fingerprint acquisition on the terminal is installed on the mounting part. By acquiring the current position information of the mounting part, the current position information of the sensor can be obtained. The current position information is of the same type as the target position information. The current position information represents the effective area for fingerprint acquisition, which can be the center position information of the effective area or the regional position information of the entire effective area.

[0081] The current position information of the installation unit can be obtained by a specialized detection device, such as a position sensor. Of course, other devices can also be used, which will not be elaborated here.

[0082] In step S130, the region represented by the target location information and the region represented by the current location information can be determined based on the degree of overlap between the region represented by the target location information and the region represented by the current location information, or based on the distance between the center position of the region represented by the target location information and the center position of the region represented by the current location information.

[0083] When determining whether a region matches the region represented by the target location information and the region represented by the current location information based on their degree of overlap, the region represented by the target location information can be recorded as the target region, and the region represented by the current location information can be recorded as the current region. If the overlap between the target region and the current region is less than a preset overlap, it means that they do not match; if the overlap between the target region and the current region is greater than or equal to the preset overlap, it means that they match.

[0084] The overlap can be the percentage of the area of ​​the overlapping area between the target area and the current area in the target area (e.g., 100%, 90%), or it can be the area value of the overlapping area between the target area and the current area (e.g., the area value of the target area).

[0085] The preset overlap degree is the same as the type of overlap degree. When the overlap degree is an area percentage, the preset overlap degree is the preset area percentage. When the overlap degree is an area value, the preset overlap degree is the preset area value.

[0086] The preset overlap can be set before the terminal leaves the factory or set by the user. Furthermore, the user can modify the preset overlap during the use of the terminal.

[0087] When determining whether two locations match based on the distance between the center of the target location information region and the center of the current location information region, the center of the target location information region can be recorded as the target location, and the center of the current location information region can be recorded as the current location. If the distance between the target location and the current location is less than or equal to a preset distance, they are considered a match. If the distance between the target location and the current location is greater than the preset distance, they are considered a mismatch.

[0088] The preset distance can be set before the terminal leaves the factory or set by the user. Furthermore, the user can modify the preset distance while using the terminal.

[0089] In step S140, if it is determined that the area represented by the target location information matches the area represented by the current location information, it means that the user's finger touched the area where the sensor is located (i.e., the effective area for fingerprint collection). Then, the position of the mounting part is kept still (i.e., the position of the sensor remains still), and the sensor directly collects fingerprint information.

[0090] In step 150, if the area represented by the target location information does not match the area represented by the current location information, it means that the user's finger is touching a location outside the sensor's area, and the sensor cannot directly collect fingerprint information. In this case, the mounting unit is driven to move to the area represented by the target location information (i.e., the sensor is driven to move to the area touched by the finger), and then the sensor collects fingerprint information.

[0091] In this method, the position of the sensor used to collect fingerprint information can be adjusted, so that the effective area of ​​fingerprint recognition is no longer limited to a fixed area, thus expanding the area of ​​the effective fingerprint recognition area. This facilitates fingerprint collection and recognition, speeds up fingerprint enrollment and unlocking, enables fingerprint recognition at any position on the screen, and improves the user experience.

[0092] In one exemplary embodiment, a fingerprint recognition method is provided. In this method, driving a mounting portion to move to an area characterized by target location information includes: S210, determine the position deviation information based on the target position information and the current position information; S220, obtain preset configuration information; S230, based on the position deviation information and the preset configuration information, determine the first drive current of the first control coil and / or the second drive current of the second control coil; S240, apply a first drive current to the first control coil, and / or apply a second drive current to the second control coil to drive the mounting part to move.

[0093] In step S210, the position deviation information may include first deviation information in a first direction and second deviation information in a second direction. The first deviation information may characterize the distance that the mounting part needs to move in the first direction, and the second deviation information may characterize the distance that the mounting part needs to move in the second direction.

[0094] In step S220, the preset configuration information may include the correspondence between position deviation information and drive current. The drive current may include a first current corresponding to the first control coil, and may also include a second current corresponding to the second control coil.

[0095] When the driving current includes a first current and a second current, the preset configuration information includes the mapping relationship between the position deviation information and the first current, and the mapping relationship between the position deviation information and the second current.

[0096] The default configuration information can be set before the terminal leaves the factory or set by the user. Furthermore, the user can modify the default configuration information while using the terminal.

[0097] In step S230, the drive current (including the first current and / or the second current) corresponding to the position deviation information determined in step S210 can be found from the preset configuration information. Then, the found first current is determined as the first drive current of the first control coil, and the found second current is determined as the second drive current of the second control coil.

[0098] In step S240, once the first drive current is determined, the first drive current can be applied to the first control coil to drive the mounting part to move along the first direction.

[0099] Once the second drive current is determined, it can be applied to the second control coil to drive the mounting part to move in the second direction.

[0100] It should be noted that in this method, if the touch position and the sensor position only deviate in the first direction, the position deviation information may only include the first deviation information in the first direction. In this case, the first driving current can only be determined based on the position deviation information and the preset configuration information. Then, by applying the first driving current to the first control coil, the mounting part is driven to move in the first direction, thereby adjusting the position of the sensor in the first direction.

[0101] Of course, if the touch position and the sensor position are only deviated in the second direction, the position deviation information may only include the second deviation information in the second direction. In this case, the second drive current can only be determined based on the position deviation information and the preset configuration information. Then, by applying the second drive current to the second control coil, the mounting part is driven to move in the second direction, thereby adjusting the position of the sensor in the second direction.

[0102] In this method, the mapping relationship between position deviation information and driving current is determined in advance, and preset configuration information including the above mapping relationship is set in the terminal. This allows the determination of the first driving current and / or the second driving current to be applied based on the position deviation information between the target position information and the current position information, so as to drive the mounting part to move to the touch position. This facilitates fingerprint acquisition and fingerprint recognition, speeds up fingerprint enrollment and unlocking, enables fingerprint recognition at any position on the screen, and improves the user experience.

[0103] In one exemplary embodiment, a fingerprint recognition method is provided. In this method, the preset configuration information may further include the correspondence between position deviation information and detection current.

[0104] The detection current may include a third current corresponding to the first detection coil, and may also include a fourth current corresponding to the second detection coil. When the detection current includes both the third and fourth currents, the preset configuration information includes the mapping relationship between the position deviation information and the third current, and the mapping relationship between the position deviation information and the fourth current.

[0105] The method may also include: S310, based on the position deviation information and the preset configuration information, determine the first detection current of the first detection coil and / or the second detection current of the second detection coil.

[0106] In this step, the detection current (including the third current and / or the fourth current) corresponding to the position deviation information determined in step S210 can be found from the preset configuration information. Then, the found third current is determined as the first detection current of the first detection coil, and the found fourth current is determined as the second detection current of the second detection coil.

[0107] After applying a first driving current to the first control coil and / or applying a second driving current to the second control coil to drive the mounting part to move, the method may further include: S410, after confirming that the mounting part is stationary, obtain the first current of the first detection coil and the second current of the second detection coil; S420, determine whether the first detected current matches the first current and whether the second detected current matches the second current; S430 collects fingerprint information.

[0108] S440, reacquire the current location information of the installation unit.

[0109] In step S410, the mounting part moves due to the first drive current and / or the second drive current. During the movement of the mounting part, the first detection coil and / or the second detection coil will generate current.

[0110] The mounting part can move a certain distance in a first direction under the action of a first driving current, which can cause the first detection coil to generate current. The mounting part can move a certain distance in a second direction under the action of a second driving current, which can cause the second detection coil to generate current.

[0111] When the mounting part comes to rest (i.e., the mounting part no longer moves), the current of the first detection coil that was detected is recorded as the first current, and the current of the second detection coil that was detected is recorded as the second current.

[0112] In step S420, it can be determined whether the difference between the first current and the first detected current is less than or equal to the first preset current, so as to determine whether the first current and the first detected current match.

[0113] Specifically, if the difference between the first current and the first detected current is less than or equal to the first preset current, then the two are determined to be a match. Otherwise, they are determined to be a mismatch.

[0114] For example, the first preset current is zero. When the difference between the first current and the first detected current is zero (i.e., the first current and the first detected current are equal), it is determined that the first current and the first detected current are matched. When the difference between the first current and the first detected current is greater than zero (i.e., the first current and the first detected current are not equal), it is determined that the first current and the first detected current are mismatched.

[0115] The method for determining whether the second current and the second detection current match can be the same as the method for determining whether the first current and the first detection current match.

[0116] If the difference between the second current and the second detected current is less than or equal to the second preset current, then the two are determined to be matched; otherwise, the two are determined to be mismatched.

[0117] The first preset current and the second preset current can be the same or different. The first preset current and / or the second preset current can be set before the terminal leaves the factory or set by the user. Furthermore, the user can modify the first preset current and / or the second preset current during the use of the terminal.

[0118] In this method, when it is determined that the first detection current matches the first current and the second detection current matches the second current, the process proceeds to step S430, where the mounting part is moved to the area represented by the target position information, and the sensor can then collect fingerprint information.

[0119] When it is determined that the first detected current does not match the first current, and / or the second detected current does not match the second current, then proceed to step S440 to reacquire the current position information of the mounting part, that is, to re-execute steps S120 and S130, and then determine the next step to be executed based on whether the area represented by the target position information matches the area represented by the re-determined current position information.

[0120] In this method, the installation part is determined to have moved to the area represented by the target position information by checking whether the first detection current matches the first current and whether the second detection current matches the second current. If the installation part is determined to have moved to the area represented by the target position information, the installation part is controlled to move according to the redefined current position information, thereby better determining the area represented by the target position information and ensuring that the sensor moves to the touch position to complete fingerprint acquisition. This improves the reliability of fingerprint acquisition, enables fingerprint recognition at any position on the screen, and enhances the user experience.

[0121] In one exemplary embodiment, a fingerprint recognition method is provided. The method may include: S510, acquires touch information; S520, Obtain the current position information of the mounting part of the sensor mounting assembly; S530 determines the target location information of the touch position based on the touch information; S540, determine whether the region represented by the target location information matches the region represented by the current location information. If they match, proceed to step S5100; if they do not match, proceed to step S550. S550 determines the position deviation information based on the target position information and the current position information; S560, based on the position deviation information and preset configuration information, determines the first driving current of the first control coil, the second driving current of the second control coil, the first detection current of the first detection coil, and the second detection current of the second detection coil; S570, a first driving current is applied to the first control coil, and a second driving current is applied to the second control coil to drive the mounting part to move.

[0122] S580, after confirming that the mounting part is stationary, obtain the first current of the first detection coil and the second current of the second detection coil; S590, determine whether the first detected current matches the first current and whether the second detected current matches the second current; if the first detected current matches the first current and the second detected current matches the second current, then execute step S5100; otherwise, execute step S520. S5100 collects fingerprint information.

[0123] In this method, all steps are executed sequentially, except for those steps that can be explicitly stated to be executed simultaneously.

[0124] Once touch information is acquired, the current position information of the mounting part can be obtained (at this time, the mounting part is not driven to move), and the target position information of the touch position can be determined at the same time based on the touch information.

[0125] Then determine whether the region represented by the target location information matches the region represented by the current location information.

[0126] If a match is found, it means that the installation part is in the area represented by the target location information, that is, the touch position is in the area where the sensor can collect fingerprints, and the sensor can be directly controlled to collect fingerprint information.

[0127] If there is a mismatch, it indicates that the touch position is not within the area where the sensor can collect fingerprints. In this case, the sensor position needs to be adjusted by moving the mounting part. Specifically, the positional deviation between the target position information and the current position information can be determined. Then, based on preset configuration information, the required first and second driving currents can be determined. Alternatively, the first detection current corresponding to the first detection coil and the second detection current corresponding to the second detection coil can be determined simultaneously after the mounting part moves to the area represented by the target position information.

[0128] Then, the control unit (which may include detection and control circuits) applies a first driving current to the first control coil and a second driving current to the second control coil to drive the mounting part to move.

[0129] After the installation unit completes its movement, that is, after the installation unit is finished, it acquires the first current of the first detection coil and the second current of the second detection coil, compares the first current with the first detection current, and compares the second current with the second detection current.

[0130] If the first current matches the first detection current, and the second current matches the second detection current, then it is determined that the mounting part has moved to the area represented by the target position information, that is, the sensor has moved to the area represented by the target position information. Then the sensor can be controlled to collect fingerprint information, and the sensor can collect the fingerprint information for this time, thus completing the fingerprint collection.

[0131] If the first current does not match the first detection current, and / or the second current does not match the second detection current, it indicates that the mounting part has not moved to the area represented by the target position information, meaning the sensor cannot collect fingerprint information. The process then returns to step S520 to reacquire the current position information of the mounting part, repeating this cycle until the sensor collects fingerprint information.

[0132] In this method, the position of the sensor used to collect fingerprint information can be adjusted, so that the effective area of ​​fingerprint recognition is no longer limited to a fixed area, thus expanding the area of ​​the effective fingerprint recognition area. This facilitates fingerprint collection and recognition, speeds up fingerprint enrollment and unlocking, enables fingerprint recognition at any position on the screen, and improves the user experience.
