[0059] In order to enable a more detailed understanding of the features and technical content of the embodiments of the present disclosure, the implementation of the embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings, which are only used for reference and do not limit the embodiments of the present disclosure. In the following technical description, in order to facilitate explanation, a plurality of details are provided to provide a full understanding of the disclosed embodiments. However, one or more embodiments can still be implemented without these details. In other cases, in order to simplify the drawings, well-known structures and devices can be simplified.

[0060] The terms "first", "second", and the like in the specification and claims of the embodiments of the present disclosure and the above-mentioned drawings are used to distinguish similar objects, and do not necessarily have to describe a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present disclosure described herein can be implemented. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion.

[0061] Unless otherwise specified, the term "a plurality of" means two or more.

[0062] In the embodiments of the present disclosure, the character " / " represents an "or" relationship between the objects before and after it. For example, A / B represents: A or B.

[0063] The term "and / or" is a description of the association between objects, which means that there can be three relationships. For example, A and / or B, which means: A or B, or, A and B, the three relationships.

[0064] The term "corresponding" can refer to an association or binding relationship, A corresponding to B means that there is an association or binding relationship between A and B.

[0065] At present, due to the advantages of simple operation, high reliability, low cost and easy integration, fingerprint unlocking is applied more and more in smart hardware. However, in actual use, users often mis-touch the fingerprint module, which causes the screen to be frequently lit, thereby consuming power and resulting in poor user experience.

[0066] Based on this, the embodiment of the present application provides a device for fingerprint identification. By changing the default position of the existing fingerprint unlocking film, when the unlocking condition is met, the fingerprint unlocking film returns to the unlocking position to unlock the device and light the screen, thereby solving the above-mentioned problem of device energy consumption caused by mis-touching the screen. Figure 1 As shown in the figure, a structure diagram of a device for fingerprint identification provided by the present application is shown. The device for fingerprint identification has an unlocking area for fingerprint identification, and the device for fingerprint identification comprises a first soft film 101, a fingerprint unlocking film 102, a second soft film 103 and a mobile device. Wherein, the mobile device is a magnetic attractor 104 in this embodiment, and the first soft film 101, the fingerprint unlocking film 102 and the second soft film 103 are contained in the fingerprint module. The first soft film 101 is arranged on the surface of the unlocking position in the unlocking area and is configured to collect user fingerprint unlocking information. The fingerprint unlocking film 102 is movably arranged in the unlocking area, and the fingerprint unlocking film 102 moves from the default position to the unlocking position to unlock the device and light the screen. The second soft film 103 is overlaid with the first soft film 101, which is used to prevent the first soft film 101 and the fingerprint unlocking film 102 from being deformed due to pressing. The middle position of the first soft film 101 and the second soft film 103 is the unlocking position of the fingerprint unlocking film 102. In addition, one end of the fingerprint unlocking film 102 is also provided with a moving part of the magnetic attractor 104, and a fixed part is arranged between the first soft film 101 and the second soft film 102. Therefore, when the fingerprint unlocking information meets the unlocking condition, the fixed part of the magnetic attractor is powered to attract the moving part by magnetic force, and the fingerprint unlocking film 102 is controlled to move from the default position to the unlocking position.

[0067] Further, the moving part of the magnetic attractor is arranged at one end of the fingerprint unlocking film in the figure, and moves to the unlocking position along the length direction. The moving part of the magnetic attractor can also be arranged on the surface of the fingerprint unlocking film and move along the width direction or the height direction, and the specific moving mode is not limited, as long as it can meet the requirement of controlling the fingerprint unlocking film to move from the default position to the unlocking position.

[0068] Wherein, after the device is used for a period of time or needs to be locked, the fingerprint unlocking film needs to be reset to the default position. Optionally, the reset manner can make the magnetic attractor be powered off and return to the original position by gravity. Of course, the manner of moving the fingerprint unlocking film to the unlocking position and resetting is not unique, and other manners can also be used to move the fingerprint unlocking film to the unlocking position. Relatively speaking, the manner of setting the magnetic attractor can better meet the precision requirements of the device.

[0069] Optionally, according to actual experience, the specification of the fingerprint module is preferably 7.6mm (length), 1.6mm (thickness), and 2mm (width), which can generally meet the unlocking requirements of human fingers. Of course, the size of the unlocking area in the device for fingerprint recognition can also be adjusted.

[0070] Optionally, the device for fingerprint recognition also includes a flexible circuit board and a connection electrical device. The flexible circuit board is used to connect the wiring of the fingerprint module and the main board circuit, so that the fingerprint module and the main console can perform bidirectional data transmission. The connection electrical device is used to place the signal pins that need to be connected with the main console on the connection electrical device, and is used to buckle the corresponding connection position of the main board during use to transmit signals. The flexible circuit board also includes a processor that can judge whether the fingerprint unlocking information meets the unlocking condition and give the corresponding control mode.

[0071] The following will be described in combination with Figure 2 The embodiment of the present application provides a method for fingerprint recognition. The method for fingerprint recognition comprises the following steps.

[0072] S201, the processor acquires fingerprint unlocking information when detecting that the unlocking area has touch pressure.

[0073] S202, the processor judges whether the fingerprint unlocking information meets the unlocking condition.

[0074] S203, the processor controls the moving device to move the fingerprint unlocking film from the default position to the unlocking position when the fingerprint unlocking information meets the unlocking condition.

[0075] In the embodiment, when the processor detects that the unlocking area on the device has touch pressure, at this time, it can be that the user has an unlocking demand, or it can be that it is caused by a false touch. At this time, the fingerprint unlocking information of the touch unlocking area is first acquired, and then the processor judges the fingerprint unlocking information to determine whether it meets the unlocking condition. In the case that the unlocking information meets the unlocking condition, the processor controls the mobile device to move the fingerprint unlocking film to the unlocking position, so as to unlock and turn on the screen of the device. Compared with the prior art, the position of the fingerprint unlocking film in the unlocked state is changed. When the device is not unlocked or the unlocking condition is not met, the fingerprint unlocking film will not move to the unlocking position, so the fingerprint unlocking device will not turn on the screen. That is, in the case of a false touch, the screen will not turn on, and in the case of meeting the unlocking condition, the screen can be unlocked and turned on. Through the above-mentioned manner, the power consumption of the device caused by the false touch of the screen can be reduced.

[0076] According to the actual data, it is known that, in the case of 2 false touches of the fingerprint module per hour, the original power consumption is 60 microamperes; and after the improvement, about 55 microamperes of power consumption can be saved.

[0077] Optionally, the step of acquiring the fingerprint unlocking information specifically comprises that the processor acquires first fingerprint information and judges whether the first fingerprint information meets a first preset condition. In the case that the first fingerprint information meets the first preset condition, second fingerprint information is acquired. The processor judges whether the second fingerprint information meets a second preset condition, and in the case that the second fingerprint information meets the second preset condition, it is determined that the unlocking condition is met.

[0078] In the embodiment, the first fingerprint information is a fingerprint pattern, which is mainly used to confirm that the unlocking person is the user of the device. The second fingerprint information includes a fingerprint contact area and / or a fingerprint contact pressure, which is used to improve the security of fingerprint unlocking, and on the other hand, it also prevents the unlocking and screen turning on caused by a false touch.

[0079] Optionally, in the present application, the fingerprint contact area and the fingerprint contact pressure can also be set to different preset unlocking areas and preset unlocking pressures according to gender and age. The specific relationship can be seen in Table 1 and Table 2. According to different ages, different preset unlocking areas and unlocking pressures are set, which can make the unlocking condition more accurate.

[0080] No. Gender Age Unlocked area (mm2) 1 Male > 14 years 15.2 2 Female > 14 years 15.2 3 Male 6-14 years 8 4 Female 6-14 years 8

[0081] Table 1

[0082] No. Gender Age Unlocked pressure (g) 1 Male > 14 years 15-30 g 2 Female > 14 years 15-30 g 3 Male 6-14 years 5-20 g 4 Female 6-14 years 5-20 g

[0083] Table 2

[0084] Optionally, the function corresponding to the number of presses can also be opened according to the number of presses in the preset time period after the device is unlocked. For example, the preset time period can be set as 15 seconds after the first press, and the corresponding function is opened according to the number of presses in the 15 seconds after the device is unlocked. For example, 1 press opens the screen; 2 presses open the fairy tale function; and 3 presses open the camera function. Thus, the device is more intelligent.

[0085] As shown in Figure 3 Another method for fingerprint identification provided by the embodiment of the present disclosure includes:

[0086] S301, the processor acquires first fingerprint information when detecting that the unlocking area has touch pressure.

[0087] S302, the processor acquires second fingerprint information when the first fingerprint information meets the first preset condition.

[0088] S303, the processor determines that the unlocking condition is met when the second fingerprint information meets the second preset condition.

[0089] S304, the processor controls the mobile device to move the fingerprint unlocking film from the default position to the unlocking position.

[0090] In this embodiment, the processor controls the fingerprint module to acquire the first fingerprint information when detecting that the unlocking area has touch pressure. When the first fingerprint information meets the first preset condition, it is confirmed that the current user is the owner of the device, and then the fingerprint module is controlled to acquire the second fingerprint information. When the second fingerprint information meets the second preset condition, it is determined that the unlocking condition is met, and the mobile device is controlled to move the fingerprint unlocking film from the default position to the unlocking position. The above method achieves hierarchical control of the unlocking process by comparing the first fingerprint information with the first preset condition and the second fingerprint information with the second preset condition, thereby improving the accuracy of the processor in determining whether the user truly wants to perform the unlocking operation and whether the user truly meets the unlocking condition. Further, the energy consumption of the fingerprint identification device is saved.

[0091] As shown in Figure 4 Another method for fingerprint identification provided by the embodiment of the present disclosure includes:

[0092] S401, the processor acquires fingerprint lines when detecting that the unlocking area has touch pressure.

[0093] S402, the processor determines whether the fingerprint lines are the same as the preset fingerprint lines. If yes, go to S403; if no, go to S406.

[0094] S403, the processor acquires the fingerprint contact area.

[0095] S404, the processor determines whether the fingerprint contact area is greater than or equal to a preset area. If yes, go to S405; if no, go to S406.

[0096] S405, the unlocking condition is met, and the processor moves the fingerprint unlocking diaphragm from the default position to the unlocking position.

[0097] S406, the processor does not move the fingerprint unlocking diaphragm, and the device does not brighten and unlock.

[0098] In this embodiment, the method for fingerprint identification is described in the case of the second fingerprint information being the fingerprint contact area. The processor acquires the fingerprint lines when detecting that the unlocking area has touch pressure, and then determines whether the fingerprint lines are the same as the preset fingerprint lines. In the case of confirming that the unlocking person is the owner of the device, the processor controls the fingerprint module to acquire the fingerprint contact area, for confirming whether the user really wants to unlock the device. The above method sets the fingerprint contact area as the second level judgment condition, reduces the possibility of bright screen unlocking due to false touch in the fingerprint identification process, and thus saves the energy consumption of the device.

[0099] As shown in FIG. 5, Figure 5 Another method for fingerprint identification provided by the embodiment of the present disclosure includes:

[0100] S501, the processor acquires the fingerprint lines when detecting that the unlocking area has touch pressure.

[0101] S502, the processor determines whether the fingerprint lines are the same as the preset fingerprint lines. If yes, go to S503; if no, go to S506.

[0102] S503, the processor acquires the fingerprint contact pressure.

[0103] S504, the processor determines whether the fingerprint contact pressure is greater than or equal to a preset pressure. If yes, go to S505; if no, go to S506.

[0104] S505, the unlocking condition is met, and the processor moves the fingerprint unlocking diaphragm from the default position to the unlocking position.

[0105] S506, the processor does not move the fingerprint unlocking diaphragm, and the device does not brighten and unlock.

[0106] In the embodiment, the method for fingerprint identification is described in the case that the second fingerprint information is the fingerprint contact pressure. The processor acquires the fingerprint ridge in the case that the touch pressure of the unlocking area is detected, and then judges whether the fingerprint ridge is the same as the preset fingerprint ridge. In the case that the unlocking person is confirmed as the owner of the device, the processor controls the fingerprint module to acquire the fingerprint contact area, for confirming whether the user really wants to unlock the device. The above method sets the fingerprint contact area as the second level judgment condition, reduces the possibility of screen-on unlocking due to false touch in the fingerprint identification process, and then saves the energy consumption of the device.

[0107] In Figure 4 and Figure 5 , the fingerprint contact area and the fingerprint contact pressure are respectively set as the second preset condition. Alternatively, both of them can be set as the second preset condition, and in the case that both of them are met, it can be determined that the unlocking condition is met. Thus, the security of device unlocking is improved, and the energy consumption loss caused by false touch is also prevented. The specific preset value can be set according to the above table 1 and table 2, which will not be described here.

[0108] Alternatively, the function corresponding to the pressing number can also be opened after the device is unlocked according to the pressing number of the unlocking area in a preset time period. For example, the preset time period can be set as 15 seconds after the first pressing, and the corresponding function is opened after the device is unlocked according to the pressing number in 15 seconds. For example, pressing once only opens the screen; pressing twice opens the fairy tale function; and pressing three times opens the camera function. Thus, the device is more intelligent.

[0109] In combination with Figure 6 , the embodiment of the disclosure provides a device for fingerprint identification, which comprises a processor (Processor) 600 and a memory (Memory) 601. Alternatively, the device can also comprise a communication interface (Communication Interface) 602 and a bus 603. Wherein, the processor 600, the communication interface 602 and the memory 601 can complete the communication among each other through the bus 603. The communication interface 602 can be used for information transmission. The processor 600 can call the logical instructions in the memory 601 to execute the method for fingerprint identification of the above-mentioned embodiments.

[0110] In addition, the logical instructions in the above-mentioned memory 601 can be realized in the form of software function unit and sold or used as an independent product when used, which can be stored in a computer readable storage medium.

[0111] The memory 601 can be configured to store software programs, computer executable programs, such as program instructions / modules corresponding to the method in the embodiments of the present disclosure. The processor 600 can execute the function application and data processing by running the program instructions / modules stored in the memory 601, that is, implement the method for fingerprint identification in the above embodiments.

[0112] The memory 601 can include a program storage area and a data storage area. The program storage area can store an operating system and at least one application required by a function. The data storage area can store data created during use of the terminal device, and the like. In addition, the memory 601 can include a high-speed random access memory, and can further include a nonvolatile memory.
