Detailed Description

Reference will now be made in detail to embodiments of the present application, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below by referring to the drawings are exemplary only for the purpose of explaining the embodiments of the present application, and are not to be construed as limiting the embodiments of the present application.

Referring to fig. 1 and fig. 2 together, the present application provides an application control method for an electronic device 100. The electronic device 100 includes a display 30 and a fingerprint recognition module 10 disposed below the display 30. The application control method comprises the following steps:

01: simultaneously acquiring fingerprint data of at least two fingers of the same user;

02: judging whether the plurality of fingerprint data are matched with the plurality of fingerprint templates; and

03: and entering a hidden application setting mode when the plurality of fingerprint data are matched with the plurality of fingerprint templates.

Referring to fig. 2, the present application further provides an electronic device 100. The electronic device 100 includes a display screen 30, a fingerprint identification module 10 disposed below the display screen 30, and a processor 20, wherein the display screen 30 is integrated with touch control and touch functions. Step 01 may be implemented by the fingerprint identification module 10. Both step 02 and step 03 may be implemented by the processor 20. That is, the fingerprint identification module 10 can be used to simultaneously acquire fingerprint data of at least two fingers of the same user. The processor 20 is operable to determine whether the plurality of fingerprint data matches the plurality of fingerprint templates and to control the electronic device 100 to enter the hidden application setting mode when the plurality of fingerprint data matches the plurality of fingerprint templates.

The electronic device 100 may be a mobile phone, a tablet computer, an intelligent wearable device (smart watch, smart bracelet, smart helmet, smart glasses, etc.), a virtual reality device, a head display device, and so on. The electronic device 100 is described as a mobile phone in the present application, but the form of the electronic device 100 is not limited to the mobile phone. The application may be an application program installed on the electronic device 100 or a file stored on the electronic device 100, such as a document, a photo, a video, and the like.

The fingerprint recognition module 10 can be a capacitive fingerprint module 12 (shown in fig. 17), an optical fingerprint module 15 (shown in fig. 18), an ultrasonic fingerprint module, and so on. Fingerprint identification module 10 sets up when display screen 30 below, fingerprint identification module 10 corresponds the fingerprint identification region on display screen 30 can be display screen 30's partial display area (regional fingerprint), also can be display screen 30's whole display area (full-screen fingerprint), as long as satisfy that fingerprint identification module 10 corresponds the fingerprint identification region on display screen 30 and is greater than predetermined ratio with display screen 30's display area's ratio, in order to guarantee that fingerprint identification module 10 can acquire the fingerprint data of a plurality of fingers simultaneously.

A plurality of fingerprint data that fingerprint identification module 10 acquireed are the fingerprint data of same user's different fingers respectively. At least two fingers of the same user include the following situations: (1) at least two fingers on the same hand of the same user, such as the left index finger and the left middle finger; (2) at least two fingers on different hands of the same user, such as a left index finger and a right index finger, etc.

The existing electronic device 100 does not provide the user with the function of hiding the application. When a user installs some applications on the electronic device 100, which are not intended to be known by others, the applications can be temporarily installed only when the applications are needed, and the applications are uninstalled after the applications are used, so that the user experience is very poor.

The electronic device 100 of the present application has a function of hiding an application. The user may trigger the electronic device 100 to enter the hidden application setting mode by entering fingerprint data for at least two fingers on the electronic device 100. In the hidden application setting mode, the user can hide an application that is desired to be hidden.

Specifically, referring to fig. 3, the electronic device 100 prestores a plurality of fingerprint templates that trigger the hidden application setting mode to be turned on, where the plurality of fingerprint templates include fingerprint templates of a plurality of fingers of the user. When the user places a plurality of fingers on display screen 30, fingerprint identification module 10 can acquire the fingerprint data of a plurality of fingers of user. Fingerprint identification module 10 sends a plurality of fingerprint data to processor 20. The processor 20 receives the plurality of fingerprint data and determines whether the plurality of fingerprint data matches the plurality of fingerprint templates.

In one example, for a plurality of fingerprint templates bound to the trigger hidden application setting mode, each fingerprint template corresponds to a fingerprint template of a finger. At this time, the processor 20 may first determine whether the number of the fingerprint data is consistent with the number of the fingerprint templates, if so, the processor 20 further matches each fingerprint data with the plurality of fingerprint templates, and if the plurality of fingerprint data are matched with the plurality of fingerprint templates one by one, it indicates that the plurality of fingerprint data are matched with the plurality of fingerprint templates, at this time, the processor 20 controls the electronic device 100 to enter a hidden application setting mode, and in the hidden application setting mode, the application state may be set to a hidden state; if the plurality of fingerprint data and the plurality of fingerprint templates are not matched one by one, the electronic device 100 operates in a normal mode in which the state of the application cannot be set to a hidden state. Or, the processor 20 may not perform the operation of determining whether the number of the fingerprint data is consistent with the number of the plurality of fingerprint templates, but directly match the plurality of fingerprint data with the plurality of fingerprint templates, and if there is any fingerprint template for which no matching fingerprint template can be found (possibly, the number of the fingerprint data is greater than the number of the fingerprint templates, or the number of the fingerprint data is consistent with the number of the fingerprint templates but the user does not use the correct finger), or there is one or more fingerprint templates that are not matched with the fingerprint data (the number of the fingerprint data is less than the number of the fingerprint templates), it indicates that the plurality of fingerprint data are not matched with the plurality of fingerprint templates, and the electronic device 100 still operates in the normal mode; if the plurality of fingerprint data matches the plurality of fingerprint templates one-to-one, the processor 20 controls the electronic device 100 to enter the hidden application setting mode.

In another example, each finger has multiple fingerprint templates. The plurality of fingerprint templates of each finger are merged into one type of fingerprint template, and the plurality of fingers correspond to the plurality of types of fingerprint templates, then the processor 20 may first determine whether the number of fingerprint data is consistent with the number of types of fingerprint templates, and if so, the processor 20 further matches each fingerprint data with the plurality of fingerprint templates in each type. If each fingerprint data can find the fingerprint template matched with each fingerprint data in the plurality of fingerprint templates, and the fingerprint template matched with each fingerprint data belongs to different types, it indicates that the plurality of fingerprint data are matched with the plurality of fingerprint templates, at this time, the processor 20 controls the electronic device 100 to enter a hidden application setting mode, and in the hidden application setting mode, the application state can be set to be a hidden state; if the plurality of fingerprint data and the plurality of fingerprint templates are not matched, the electronic device 100 operates in a normal mode in which the state of the application cannot be set to a hidden state. Alternatively, the processor 20 may not perform the operation of determining whether the number of fingerprint data is consistent with the number of types of fingerprint templates, but directly match each fingerprint data with a plurality of fingerprint templates in each type. If any fingerprint data cannot find the fingerprint template matched with the fingerprint data, or if a plurality of fingerprint templates in one or more types cannot find the fingerprint data matched with the fingerprint template, the plurality of fingerprint data are not matched with the plurality of fingerprint templates, and the electronic device 100 still works in a common mode; if each fingerprint data can find the fingerprint template matched with each fingerprint data in the plurality of fingerprint templates, and the fingerprint template matched with each fingerprint data belongs to different types, it indicates that the plurality of fingerprint data are matched with the plurality of fingerprint templates, and at this time, the processor 20 controls the electronic device 100 to enter the hidden application setting mode.

In the application control method, the electronic equipment 100 provides the function of hiding the application for the user, the user can realize the opening of the hidden application setting mode by inputting the fingerprint data on the electronic equipment 100, the user can hide the application in the hidden application setting mode, the operation is simple, the privacy of the use habit of the user is greatly guaranteed, and the user experience is good.

In addition, in the application control method, the user triggers the hidden application setting mode to be started through multiple fingers, so that the problem of false triggering can be avoided. It can be understood that the user usually operates the electronic device 100 with a single finger, and if the hidden application setting mode is opened by using the single finger trigger, the probability of false trigger is greatly increased, and the probability of false trigger caused by multi-finger trigger is low.

In addition, among the electronic equipment 100 of this application, fingerprint identification module 10 sets up in display screen 30 below, and fingerprint identification module 10 can discern the fingerprint data of a plurality of fingers simultaneously, and user's operation has been simplified to this kind of mode of triggering, has increased and has hidden the probability that uses the mode of setting to be opened by success. It can be understood that if the hidden application setting mode is triggered by using single-point fingerprint identification, software logic complexity needs to be increased to avoid the probability that the hidden application setting mode is triggered by mistake, but the increased software logic complexity means that a requirement needs to be made on the operation of a user, for example, a user is required to put a single finger in a single-point fingerprint identification area in sequence, and the interval time between two fingers in the fingerprint identification area cannot exceed a preset interval duration, and the like. The fingerprint identification that the fingerprint identification module 10 of this application corresponds is regional great, can acquire the fingerprint data of a plurality of fingers simultaneously, and the user only need can successfully trigger through simple operation and hide the application and set up the mode.

Referring to fig. 4, in some embodiments, each fingerprint data includes a fingerprint image and a first touch pressure, each finger corresponds to a fingerprint template, each fingerprint template includes an image template and a predetermined touch pressure, and the predetermined touch pressures of the fingerprint templates are the same. Step 02 includes:

0211: calculating the current matching degree between each fingerprint image and each image template;

0212: judging whether a current matching degree with a value larger than the first matching degree exists in the plurality of current matching degrees;

0213: if so, taking the fingerprint template corresponding to the current matching degree with the value larger than the first matching degree as the fingerprint template matched with the fingerprint data;

0214: if not, calculating a first difference value between each first touch pressure and a preset touch pressure;

0215: adjusting the first matching degree to a second matching degree according to the first difference, wherein the first matching degree is greater than the second matching degree; and

0216: and taking the fingerprint template corresponding to the current matching degree with the value larger than the second matching degree as the fingerprint template matched with the fingerprint data.

Referring to FIG. 2, in some embodiments, step 0211, step 0212, step 0213, step 0214, step 0215 and step 0216 can all be implemented by processor 20. That is, the processor 20 is further configured to calculate a current matching degree between each fingerprint image and each image template and determine whether there is a current matching degree having a value greater than the first matching degree among the plurality of current matching degrees. If so, the processor 20 takes the fingerprint template corresponding to the current matching degree with the value greater than the first matching degree as the fingerprint template matched with the fingerprint data; if not, the processor 20 calculates a first difference between each first touch pressure and a predetermined touch pressure, adjusts the first matching degree to a second matching degree according to the first difference, and takes the fingerprint template corresponding to the current matching degree with a value greater than the second matching degree as the fingerprint template matched with the fingerprint data, wherein the first matching degree is greater than the second matching degree.

Specifically, when the processor 20 acquires a plurality of fingerprint data, it is necessary to match the plurality of fingerprint data with a plurality of fingerprint templates. Fingerprint data includes these two data of fingerprint image and first touch pressure, and when the fingerprint image opened hidden application setting mode for the user through electronic equipment 100, the image of user's finger that fingerprint identification module 10 obtained, first touch pressure refers to the pressure that the user opened finger touch display screen 30 when hidden application setting mode through electronic equipment 100. Every fingerprint template all includes image template and predetermined touch pressure, the image template is the fingerprint image that fingerprint identification module 10 obtained when the user types a plurality of fingerprint templates so that electronic equipment 100 binds a plurality of fingerprint templates with open hidden application setting mode through electronic equipment 100, predetermined touch pressure is the user types a plurality of fingerprint templates so that electronic equipment 100 binds a plurality of fingerprint templates with open hidden application setting mode through electronic equipment 100, user's finger touch display screen 30's pressure, predetermined touch pressure is that electronic equipment 100 sets for in advance, in the binding process, electronic equipment 100 can indicate the user to touch display screen 30 with predetermined touch pressure.

Suppose there are two fingerprint data, F₁、F₂Fingerprint data F₁The fingerprint image in (1) is F_I1The first touch pressure is F_N1Fingerprint data F₂The fingerprint image in (1) is F_I2Touch pressure of F_N2(ii) a The fingerprint templates are two and are respectively T₁、T₂Fingerprint template T₁The image template in (1) is T_I1Predetermined touch pressure of T_N0Fingerprint template T₂The image template in (1) is T_I2Predetermined touch pressure of T_N0. The processor 20 first calculates F separately_I1And T_I1、T_I2Current degree of match M between₁₁、M₁₂And separately calculate F_I2And T_I1、T_I2Current degree of match M between₂₁、M₂₂. The processor 20 determines whether there is a current matching degree having a value greater than the first matching degree among a plurality of current matching degrees calculated from the same fingerprint image, i.e., determines M₁₁、M₁₂Whether there is a current matching degree having a value greater than the first matching degree, and determining M₂₁、M₂₂If there is a current degree of match with a value greater than the first degree of match. If M is₁₁、M₁₂There is a current degree of matching with a value greater than the first degree of matching, assumed to be M₁₁And M is₂₁、M₂₂There is a current degree of matching, assumed to be M, with a value greater than the first degree of matching₂₂Then processor 20 considers M₁₁Corresponding fingerprint template T₁I.e. with the fingerprint data F₁Matching fingerprint templates, M₂₂Corresponding fingerprint template T₂I.e. with the fingerprint data F₂A matching fingerprint template. If M is₁₁、M₁₂There is no current matching degree with a value greater than the first matching degree, the processor 20 calculates the first touch pressure F_N1With a predetermined touch pressure T_N0A first difference N therebetween₁₀According to the first difference N₁₀Calculating a second degree of match with the first degree of match, the second degree of match being less than the first degree of match, and processor 20 then calculating from M₁₁、M₁₂The selected value is greater than the second matching degreeDegree of front match, assumed to be M₁₁Then processor 20 will M₁₁Corresponding fingerprint template T₁As and fingerprint data F₁A matching fingerprint template. Likewise, if M₂₁、M₂₂There is no current matching degree with a value greater than the first matching degree, the processor 20 calculates the first touch pressure F_N2With a predetermined touch pressure T_N0A first difference N therebetween₂₀According to the first difference N₂₀Calculating a second degree of match with the first degree of match, the second degree of match being less than the first degree of match, and processor 20 then calculating from M₂₁、M₂₂Selecting the current matching degree with the value larger than the second matching degree, wherein the current matching degree is assumed to be M₂₂Then processor 20 will M₂₂Corresponding fingerprint template T₂As and fingerprint data F₂A matching fingerprint template.

It can be understood that when the finger of the user touches the display screen 30 with different pressures, the fingerprint images acquired by the fingerprint identification module 10 will be different. For example, when the pressure of the user touching the display screen 30 is large, the fingerprint identification module 10 obtains more information of the fingerprint image, and the integrity of the fingerprint image is high; and when the pressure that the user touched display screen 30 was less, the information of the fingerprint image that fingerprint identification module 10 obtained was less, and fingerprint image integrity is lower. Since the pressure (i.e., the first touch pressure) of the user touching the display screen 30 may be different from the predetermined touch pressure during the process of the user triggering the hidden application setting mode to be turned on through the electronic device 100, the current matching degree between the fingerprint image and the accurate image template may not be high. At this time, if a higher matching degree (i.e., a first matching degree) is set, it may result in that an image template matching the fingerprint image cannot be found, and further, the hidden application setting mode cannot be successfully opened; and the matching degree is reduced according to the first difference between the first touch pressure and the preset touch pressure, namely the first matching degree is adjusted to be the second matching degree, so that the successful matching between the fingerprint image and the accurate image template can be ensured, and the probability that the hidden application setting mode is successfully opened is improved.

Further, for step (ii)0211 to 0216, assuming that the number of fingerprint templates is n₀In the process of matching the plurality of fingerprint data and the plurality of fingerprint templates, if the first number n exists, the processor 20 determines that the first number n is greater than the second number n₁Finds a fingerprint template matching it, then the remaining (n)₀-n₁) One fingerprint data (i.e. the second amount of fingerprint data) only needs to be compared with the remaining (n)₀-n₁) Matching individual fingerprint templates without n₀The fingerprint templates are matched, so that the time for matching the fingerprint data with the fingerprint templates can be reduced. It can be understood that a plurality of fingerprint data are the data of different fingers respectively, and a plurality of fingerprint templates are the template of different fingers respectively, so, after fingerprint template and a fingerprint data match, this fingerprint template just can not match with other fingerprint data, and at this moment, only need not carry out the fingerprint data that matches and match with remaining fingerprint template can.

Referring to fig. 5, in some embodiments, before step 01, the application control method further includes:

041: when the fingers of the user touch the display screen 30, acquiring a second touch pressure of each finger touching the display screen 30;

042: calculating a second difference between the second touch pressure and the predetermined touch pressure;

043: prompting the user to adjust the second touch pressure when the second difference is greater than the predetermined difference to change the second difference such that the second difference is less than the predetermined difference;

044: acquiring a fingerprint image of each finger when the second difference is smaller than a predetermined difference;

045: taking the fingerprint image of each finger as an image template, and packaging each image template and preset touch pressure into a fingerprint template;

046: and binding the plurality of fingerprint templates with the start of the trigger hidden application setting mode.

Referring back to FIG. 2, in some embodiments, step 041 may be implemented by display screen 30.

Steps

042, 043, 045 and 046 may all be implemented by the processor 20. Step 044 may be implemented by the fingerprint identification module 10. That is, the display screen 30 may be used to acquire the second touch pressure of each finger touching the display screen 30 when the user's finger touches the display screen 30. The processor 20 may be further configured to calculate a second difference between the second touch pressure and the predetermined touch pressure, and prompt the user to adjust the second touch pressure to change the second difference when the second difference is greater than the predetermined difference such that the second difference is less than the predetermined difference. The fingerprint identification module 10 may be further configured to obtain a fingerprint image of each finger when the second difference is less than the predetermined difference. The processor 20 is further operable to treat the fingerprint image of each finger as an image template, encapsulate each image template with a predetermined touch pressure as one fingerprint template, and bind a plurality of fingerprint templates with the trigger hidden application setup mode open.

The user clicks a "fingerprint" option in "fingerprint, face and password" in the setting interface of the electronic device 100 to enter a multi-finger entry interface, and in the multi-finger entry interface, the user can enter a plurality of fingers and bind the entered fingers with the activation of the hidden application setting mode. Specifically, during the multi-finger entry process, the electronic device 100 prompts the user to place a plurality of fingers in the fingerprint identification area, for example, please refer to fig. 6, and display "please place at least two fingers of your on the fingerprint identification area: such as the left index finger + the left middle finger, to prompt the user to place multiple fingers within the fingerprint identification area. Subsequently, the display screen 30 obtains a second touch pressure of each finger of the user, where the second touch pressure is a pressure of the user touching the display screen 30 without being prompted by the electronic device 100 in the process of binding the plurality of fingerprint templates and the trigger hidden application setting mode. The processor 20 calculates a second difference between the second touch pressure of each finger and the predetermined touch pressure, and if the second difference is greater than the predetermined difference, the processor 20 controls the display 30 to prompt the user to adjust the second touch pressure such that the second difference between the adjusted second touch pressure and the predetermined touch pressure is less than or equal to the predetermined difference. When the second difference is less than or equal to the predetermined difference, the fingerprint recognition module 10 acquires the fingerprint images of a plurality of fingers simultaneously, and sends the fingerprint images of a plurality of fingers to the processor 20. The processor 20 takes the fingerprint image of each finger as an image template and encapsulates each image template with a predetermined touch pressure as one fingerprint template. The processor 20 then binds the plurality of fingerprint templates to triggering the hidden application set mode to open.

Referring to fig. 7, in some embodiments, each fingerprint data includes a fingerprint image and a first touch pressure, each fingerprint corresponds to a fingerprint template, and each fingerprint template includes an image template and a second touch pressure. Step 02 includes:

0221: calculating the current matching degree between each fingerprint image and each image template;

0222: judging whether a current matching degree with a value larger than the first matching degree exists in the plurality of current matching degrees;

0223: if so, taking the fingerprint template corresponding to the current matching degree with the value larger than the first matching degree as the fingerprint template matched with the fingerprint data;

0224: if not, calculating a first difference value between each first touch pressure and each second touch pressure;

0225: adjusting the first matching degree to a second matching degree according to the first difference, wherein the first matching degree is greater than the second matching degree, and each fingerprint template corresponds to one second matching degree; and

0226: and taking the fingerprint template corresponding to the current matching degree with the value larger than the second matching degree as the fingerprint template matched with the fingerprint data.

Referring back to fig. 2, step 0221, step 0222, step 0223, step 0224, step 0225, and step 0226 may all be implemented by processor 20. That is, the processor 20 is further configured to calculate a current matching degree between each fingerprint image and each image template, and determine whether there is a current matching degree having a value greater than the first matching degree among the plurality of current matching degrees. If so, the processor 20 takes the fingerprint template corresponding to the current matching degree with the value greater than the first matching degree as the fingerprint template matched with the fingerprint data; if not, the processor 20 calculates a first difference between each first touch pressure and each second touch pressure, adjusts the first matching degree to a second matching degree according to the first difference, and takes the fingerprint template corresponding to the current matching degree with a value greater than the second matching degree as the fingerprint template matched with the fingerprint data, wherein the first matching degree is greater than the second matching degree, and each fingerprint template corresponds to one second matching degree.

Specifically, when the processor 20 acquires the fingerprint data, the fingerprint data needs to be matched with the fingerprint template. The fingerprint image is an image of a finger of the user acquired by the fingerprint identification module 10 when the hidden application setting mode is opened by the user through the electronic device 100, and the first touch pressure refers to a pressure of the finger touching the display screen 30 when the hidden application setting mode is opened by the user through the electronic device 100. The fingerprint template includes image template and second touch pressure, and the image template is the fingerprint image that fingerprint identification module 10 obtained when making electronic equipment 100 bind a plurality of fingerprint templates and opening hidden application setting mode for the user inputs a plurality of fingerprint templates through electronic equipment 100, and second touch pressure is opening a plurality of fingerprint templates and triggering hidden application setting mode and binding the in-process, and the user is at the pressure that does not indicate under the condition of electronic equipment 100 suggestion that the finger touches display screen 30.

Suppose there are two fingerprint data, F₁、F₂Fingerprint data F₁The fingerprint image in (1) is F_I1The first touch pressure is F_N1Fingerprint data F₂The fingerprint image in (1) is F_I2The first touch pressure is F_N2(ii) a The fingerprint templates are two and are respectively T₁、T₂Fingerprint template T₁The image template in (1) is T_I1The second touch pressure is T_N1Fingerprint template T₂The image template in (1) is T_I2The second touch pressure is T_N2. The processor 20 first calculates F separately_I1And T_I1、T_I2Current degree of match M between₁₁、M₁₂And separately calculate F_I2And T_I1、T_I2Current degree of match M between₂₁、M₂₂. The processor 20 determines whether a plurality of current matching degrees calculated from the same fingerprint image are storedJudging M at the current matching degree with the value larger than the first matching degree₁₁、M₁₂Whether there is a current matching degree having a value greater than the first matching degree, and determining M₂₁、M₂₂If there is a current degree of match with a value greater than the first degree of match. If M is₁₁、M₁₂There is a current degree of matching with a value greater than the first degree of matching, assumed to be M₁₁And M is₂₁、M₂₂There is a current degree of matching, assumed to be M, with a value greater than the first degree of matching₂₂Then processor 20 considers M₁₁Corresponding fingerprint template T₁I.e. with the fingerprint data F₁Matching fingerprint templates, M₂₂Corresponding fingerprint template T₂I.e. with the fingerprint data F₂A matching fingerprint template. If M is₁₁、M₁₂There is no current matching degree with a value greater than the first matching degree, the processor 20 calculates the first touch pressures F respectively_N1And a second touch pressure T_N1A first difference N therebetween₁₁And a first touch pressure F_N1And a second touch pressure T_N2A first difference N therebetween₁₂. Processor 20 then bases on the first difference N₁₁Calculating a second matching degree of the corresponding fingerprint template T1 according to the first matching degree, and calculating a second matching degree according to the first difference value N₁₂And calculating a second matching degree of the corresponding fingerprint template T2 according to the first matching degree, wherein the second matching degree corresponding to each fingerprint template is smaller than the first matching degree. Processor 20 then determines F_I1And T_I1Current degree of match M between₁₁If the current matching degree is greater than the second matching degree of the corresponding fingerprint template T1, if so, the processor 20 will determine the current matching degree M₁₁Corresponding fingerprint template T₁As and fingerprint data F₁Matching fingerprint templates; if not, processor 20 determines F_I1And T_I2Current degree of match M between₁₂If the current matching degree is greater than the second matching degree of the corresponding fingerprint template T2, if so, the processor 20 will determine the current matching degree M₁₂Corresponding fingerprint template T₂As and fingerprint data F₂Matching fingerprint templates; if not, the processor 20 recognizes the fingerprint data F₁Can not be applied to a plurality of fingerprint mouldsAnd finding a fingerprint template matched with the template in the board, and hiding the failure of the opening of the application setting mode. Finding and fingerprinting data F₂Matching fingerprint template with search and fingerprint data F₁The matching fingerprint templates are in the same manner and will not be described herein.

It can be understood that when the pressure of the user touching the display screen 30 is different, the fingerprint images acquired by the fingerprint identification module 10 are also different. Since the pressure (i.e., the first touch pressure) of the user touching the display screen 30 and the pressure (i.e., the second touch pressure) of the user binding the plurality of fingerprint templates may be different from the pressure (i.e., the second touch pressure) of the user touching the display screen 30 when the hidden application setting mode is triggered to be turned on in the process that the user triggers the hidden application setting mode to be turned on through the electronic device 100, the current matching degree between the fingerprint image and the accurate image template may not be very high. At this time, if a higher matching degree (i.e., a first matching degree) is set, it may result in that an image template matching the fingerprint image cannot be found, and further, the hidden application setting mode cannot be successfully opened; and the matching degree is reduced according to the first difference between the first touch pressure and the second touch pressure, namely the first matching degree is adjusted to the second matching degree, so that the successful matching between the fingerprint image and the accurate image template can be ensured, and the probability that the hidden application setting mode is successfully opened is improved.

Likewise, for the embodiment shown in steps 0221-0226, assume that the number of fingerprint templates is n₀In the process of matching the plurality of fingerprint data and the plurality of fingerprint templates, if the first number n exists, the processor 20 determines that the first number n is greater than the second number n₁Finds a fingerprint template matching it, then the remaining (n)₀-n₁) One fingerprint data (i.e. the second amount of fingerprint data) only needs to be compared with the remaining (n)₀-n₁) Matching individual fingerprint templates without n₀The fingerprint templates are matched, so that the time for matching the fingerprint data with the fingerprint templates can be reduced.

Referring to fig. 8, in some embodiments, before step 01, the application control method further includes:

051: when the fingers of the user touch the display screen 30, acquiring a second touch pressure of each finger touching the display screen 30 and a fingerprint image of each finger;

052: taking the fingerprint image of each finger as an image template, and packaging the image template of each finger and the second touch pressure of the finger into one fingerprint template;

053: and binding the plurality of fingerprint templates with the start of the trigger hidden application setting mode.

Referring back to fig. 2, in some embodiments, the step 051 can be implemented by the display 30 and the fingerprint identification module 10 together. Both

steps

052 and 053 may be implemented by processor 20. That is to say, when the user's finger touches the display screen 30, the display screen 30 can be used to obtain the second touch pressure of each finger touching the display screen 30, and the fingerprint identification module 10 can be used to obtain the fingerprint image of each finger. The processor 20 is further operable to use the fingerprint image of each finger as an image template, encapsulate the image template of each finger with the second touch pressure of the finger as one fingerprint template, and bind a plurality of fingerprint templates with the trigger hidden application setup mode open.

The user clicks a "fingerprint" option in "fingerprint, face and password" in the setting interface of the electronic device 100 to enter a multi-finger entry interface, and in the multi-finger entry interface, the user can enter a plurality of fingers and bind the entered fingers with the activation of the hidden application setting mode. Specifically, during multi-finger entry, the electronic device 100 may prompt the user to place multiple fingers within the fingerprint identification area. Subsequently, the display screen 30 obtains a second touch pressure of each finger of the user, where the second touch pressure is a pressure of the user touching the display screen 30 without being prompted by the electronic device 100 in the process of binding the plurality of fingerprint templates and the trigger hidden application setting mode. Fingerprint identification module 10 will acquire the fingerprint image of each finger and send the fingerprint image of each finger to processor 20. The processor 20 takes the fingerprint image of each finger as an image template and encapsulates the image template of each finger with the second touch pressure of the finger as one fingerprint template. The processor 20 then binds the plurality of fingerprint templates to triggering the hidden application set mode to open.

Referring to fig. 9, in some embodiments, each fingerprint data includes a fingerprint image and a first touch pressure, each finger corresponds to a plurality of fingerprint templates, each fingerprint template includes an image template and a second touch pressure, and the second touch pressure of the plurality of fingerprint templates corresponding to each finger is different. Step 02 includes:

0231: respectively calculating a first difference value between the first touch pressure and each second touch pressure of each finger, and taking the fingerprint template corresponding to the first difference value with the minimum value as the fingerprint template of the finger;

0232: calculating the current matching degree between each fingerprint image and the image template of one fingerprint template in each finger;

0233: and taking the fingerprint template corresponding to the current matching degree with the value larger than the first matching degree as the fingerprint template matched with the fingerprint data.

Referring back to fig. 2, in some embodiments,

steps

0231, 0232 and 0233 may all be implemented by a processor 20. That is, the processor 20 may be further configured to calculate a first difference between the first touch pressure and each second touch pressure in each finger, respectively, take the fingerprint template corresponding to the first difference with the smallest value as the fingerprint template of the finger, calculate a current matching degree between each fingerprint image and the image template of one fingerprint template in each finger, and take the fingerprint template corresponding to the current matching degree with a value greater than the first matching degree as the fingerprint template matched with the fingerprint data.

Specifically, when the processor 20 acquires the fingerprint data, the fingerprint data needs to be matched with the fingerprint template. The fingerprint image is an image of a finger of the user acquired by the fingerprint identification module 10 when the hidden application setting mode is opened by the user through the electronic device 100, and the first touch pressure refers to a pressure of the finger touching the display screen 30 when the hidden application setting mode is opened by the user through the electronic device 100. Every finger all has a plurality of fingerprint templates, every fingerprint template all includes image template and second touch pressure, the image template is the user and types a plurality of fingerprint templates so that electronic equipment 100 binds a plurality of fingerprint templates with open hidden application setting mode the fingerprint image that fingerprint identification module 10 obtained, second touch pressure is opening a plurality of fingerprint templates and triggering hidden application setting mode and binding the in-process, the user is in the pressure that the display screen 30 was touched to the finger under the condition of not having the suggestion of electronic equipment 100, the second touch pressure inequality of a plurality of fingerprint templates in same finger.

Suppose there are two fingerprint data, F₁、F₂Fingerprint data F₁The fingerprint image in (1) is F_I1The first touch pressure is F_N1Fingerprint data F₂The fingerprint image in (1) is F_I2The first touch pressure is F_N2(ii) a Four fingerprint templates are provided, and are respectively T₁、T₂、T₃、T₄Wherein, the fingerprint template T₁And T₂Being a fingerprint template for a finger, fingerprint template T₃And T₄Is a fingerprint template of another finger. Fingerprint template T₁The image template in (1) is T_I1The second touch pressure is T_N1Fingerprint template T₂The image template in (1) is T_I2The second touch pressure is T_N2Fingerprint template T₃The image template in (1) is T_I3The second touch pressure is T_N3Fingerprint template T₄The image template in (1) is T_I4The second touch pressure is T_N4. The processor 20 first calculates the first touch pressures F respectively_N1And a second touch pressure T_N1Second touch pressure T_N2A first difference therebetween, and respectively calculating a first touch pressure F_N2And a second touch pressure T_N3Second touch pressure T_N4A first difference therebetween. Subsequently, the processor 20 derives the first touch pressure F_N1And a second touch pressure T_N1First difference value of (1), first touch pressure F_N1And a second touch pressure T_N2The fingerprint template corresponding to the first difference is taken as the fingerprint template of a finger, and the selected fingerprint template is assumed to be T₁(ii) a The processor 20 also derives a first touch pressure F_N1And a second touch pressure T_N3First difference value of (1), first touch pressure F_N1And a second touch pressure T_N4The fingerprint template corresponding to the first difference is taken as the fingerprint template of another finger, and the selected fingerprint template is assumed to be T₄. Subsequently, the processor 20 calculates the fingerprint images as F respectively_I1With fingerprint template T₁、T₄Current degree of match M between₁₁、M₁₄Processor 20 slave M₁₁And M₁₄Selecting a fingerprint template with a value greater than the first matching degree as fingerprint data F₁Matching fingerprint templates, let M₁₁If it is greater than the first matching degree, the processor 20 considers M₁₁Corresponding fingerprint template T₁I.e. with the fingerprint data F₁A matching fingerprint template. If M is₁₁And M₁₄Are less than the first degree of match, the processor 20 recognizes the fingerprint data F₁The fingerprint template matched with the fingerprint template can not be found in the plurality of fingerprint templates, and the opening failure of the application setting mode is hidden. Finding and fingerprinting data F₂Matching fingerprint template with search and fingerprint data F₁The matching fingerprint templates are in the same manner and will not be described herein.

It can be understood that when the pressure of the user touching the display screen 30 is different, the fingerprint images acquired by the fingerprint identification module 10 are also different. In order to quickly and accurately determine whether a fingerprint template matched with fingerprint data exists in a plurality of fingerprint templates, for each finger, the electronic device 100 may pre-store a plurality of fingerprint templates under different second touch pressures, and in the process of actually triggering the hidden application setting mode to be opened, the processor 20 may first perform screening of the fingerprint templates according to a first difference between the first touch pressure and the second touch pressure, and then match the fingerprint image with an image template in the screened fingerprint template.

Similarly, for the embodiment shown in steps 0231 to 0233, it is assumed that the number of types of fingerprint templates (a plurality of fingerprint templates corresponding to one finger are of one type) is n₀In the process of matching the plurality of fingerprint data and the plurality of fingerprint templates, if the first number n exists, the processor 20 determines that the first number n is greater than the second number n₁Finds a fingerprint template matching it, then the remaining (n)₀-n₁) One fingerprint data (i.e. the second amount of fingerprint data) only needs to be compared with the remaining (n)₀-n₁) Matching of individual types of fingerprint templates without matching with n₀The fingerprint templates of the various types are matched, so that the time for matching the plurality of fingerprint data with the plurality of fingerprint templates can be reduced.

Referring to fig. 10, in some embodiments, before step 01, the application control method further includes:

061: when the fingers of the user touch the display screen 30, acquiring a second touch pressure of each finger touching the display screen 30 and a fingerprint image of each finger for multiple times, wherein the second touch pressures of each finger touching the display screen 30 are different;

062: taking the fingerprint image of each finger when each finger touches the display screen 30 as an image template, and packaging the image template of the finger and the second touch pressure of the finger into one fingerprint template;

063: and binding the plurality of fingerprint templates with the start of the trigger hidden application setting mode.

Referring back to fig. 2, in some embodiments, step 061 may be implemented by the display 30 and the fingerprint recognition module 10 together. Both

steps

062 and 063 can be implemented by the processor 20. That is to say, when the user's finger touches the display screen 30, the display screen 30 is used for obtaining the second touch pressure of each finger touching the display screen 30 for a plurality of times, the fingerprint identification module 10 is used for obtaining the fingerprint image of each finger for a plurality of times, and the second touch pressure of each finger touching the display screen 30 every time is different. The processor 20 may be configured to take the fingerprint image of each finger touching the display screen 30 each time as an image template, encapsulate the image template of the finger and the second touch pressure of the finger into one fingerprint template, and bind a plurality of fingerprint templates with the triggered hidden application setting mode being opened.

The user clicks a "fingerprint" option in "fingerprint, face and password" in the setting interface of the electronic device 100 to enter a multi-finger entry interface, and in the multi-finger entry interface, the user can enter a plurality of fingers and bind the entered fingers with the activation of the hidden application setting mode. Specifically, in the multi-finger input process, the electronic device 100 prompts the user to perform the operation of placing a plurality of fingers in the fingerprint identification area for a plurality of times, and when the fingers are placed in the fingerprint identification area for each time, the pressure of the fingers touching the display screen 30 is different, the display screen 30 obtains the second touch pressure of each finger of the user for a plurality of times, and the fingerprint identification module 10 obtains the fingerprint image of each finger for a plurality of times. The fingerprint identification module 10 sends the fingerprint image of each finger touching the display screen 30 each time to the processor 20. Subsequently, the processor 20 takes the fingerprint image of each finger touching the display screen 30 at a time as an image template, and encapsulates the image template of each finger and the second touch pressure of the finger when touching the display screen 30 at the time as one fingerprint template. The processor 20 then binds the plurality of fingerprint templates to triggering the hidden application set mode to open.

Referring to fig. 11, in some embodiments, before step 01, the application control method further includes:

071: judging whether at least two fingers touch the display screen 30;

072: if at least two fingers touch the display screen 30, judging whether the touch time of the at least two fingers touching the display screen 30 is longer than a preset touch time; and

when the touch time is longer than the predetermined touch time, the step of simultaneously acquiring the fingerprint data of at least two fingers of the same user through the fingerprint identification module 10 is performed.

Referring back to fig. 2, in some embodiments,

steps

071 and 072 can be implemented by processor 20. That is, the processor 20 is further configured to determine whether there are at least two fingers touching the display screen 30, and determine whether a touch time of the at least two fingers touching the display screen 30 is greater than a predetermined touch time period when the at least two fingers touch the display screen 30. When the touch time is longer than the predetermined touch time, the fingerprint identification module 10 simultaneously acquires the fingerprint data of at least two fingers of the same user.

Specifically, the user needs to enter multiple fingers on the electronic device 100 at the same time to trigger the opening of the hidden application setting mode. The display screen 30 reports the touch points to the processor 20, and the processor 20 determines whether a plurality of fingers touch the display screen 30 according to the touch points. In one example, the processor 20 determines whether there are multiple fingers touching the display screen 30 according to the touch points by: and judging whether at least two central touch points exist, wherein the distance between each central touch point and a plurality of non-central touch points in a preset area is smaller than or equal to a preset distance, and the preset area is an area formed by expanding outwards in a preset shape by taking the central touch point as an origin. If there are at least two center touch points, it is assumed that there are multiple fingers touching the display screen 30; if there are not at least two center touch points, then it is assumed that there are no more fingers touching the display screen 30. If no more than one finger touches the display screen 30, the processor 20 does not further determine whether the touch time is greater than the predetermined touch time period. If a plurality of fingers touch the display screen 30, the processor 20 further determines whether the touch time is greater than or equal to the predetermined touch time, that is, whether the duration of the plurality of fingers touching the display screen 30 is greater than or equal to the predetermined touch time. If the touch time is longer than or equal to the preset touch time, the processor 20 controls the fingerprint identification module 10 to be opened, so that the fingerprint identification module 10 can acquire the fingerprint data of a plurality of fingers simultaneously. If the touch duration is less than the predetermined touch duration, the processor 20 does no action.

It is understood that the processor 20 first determines whether there are more than one fingers touching the display 30, and if not, it indicates that the user does not need to enter the hidden application setting mode by the electronic device 100, and then the processor 20 does not further perform step 072, so that the power consumption of the processor 20 can be reduced. In addition, even if processor 20 judges that there are a plurality of fingers touching display screen 30, processor 20 still can further judge whether touch time is more than or equal to predetermined touch duration, just open fingerprint identification module 10 and obtain fingerprint data when touch time is more than predetermined touch duration, so, put a plurality of fingers on display screen 30 but when the user does not need in fact electronic equipment 100 to get into hidden application setting mode at the user mistake, can avoid hiding the problem that application setting mode is triggered by mistake.

Referring to fig. 12, in some embodiments, the application control method further includes:

081: determining a target application to be hidden in a plurality of applications according to a first input of a user; and

082: the target application is hidden according to a second input of the user, and after the target application is hidden, the display screen 30 does not display the target application in the normal mode.

Referring back to FIG. 2, in some embodiments, step 081 and step 082 may both be implemented by processor 20. That is, the processor 20 may be further configured to determine a target application to be hidden among the plurality of applications according to a first input of the user, and hide the target application according to a second input of the user. After the target application is hidden, the display screen 30 does not display the target application in the normal mode.

Specifically, please refer to fig. 3 and 13, in the normal mode, the user inputs the fingerprint data of a plurality of fingers on the electronic device 100, and after the processor 20 determines that the fingerprint data of the plurality of fingers matches with the plurality of fingerprint templates, the processor 20 controls the electronic device 100 to enter the hidden application setting mode. In the hidden application setting mode, the display screen 30 displays all applications. The user may long-press (i.e., first input) a certain application that has not been set as hidden, and after detecting the long-press operation of the user, the display screen 30 determines the application that the user long-pressed as a target application to be hidden, and displays options such as "application information", "hidden", and the like at a peripheral position of the target application for the user to select. After the user clicks (i.e., the second input) "hide", the processor 20 controls the display screen 30 to hide the target application. Specifically, when the electronic device 100 exits the hidden application setting mode, that is, the electronic device 100 is in the normal mode, the target application is not displayed on the display screen 30. In this way, hiding of the target application can be achieved.

Further, referring back to fig. 12, in some embodiments, after step 082, the applying the control method further comprises:

083: and in the hidden application setting mode, changing the first icon of the target application into the second icon after the target application is hidden.

Referring back to fig. 2, in some embodiments, step 083 may be implemented by processor 20. That is, the processor 20 may be further configured to change the first icon of the target application to the second icon after the target application is hidden in the hidden application setting mode.

Specifically, when the target application is not hidden, the target application is displayed with the first icon regardless of the normal mode or the hidden application setting mode. When the user presses the target application for a long time and clicks "hide" while the display screen 30 displays the "hide" option, the target application is hidden, and the hidden target application is still displayed in the hidden application setting mode. But to facilitate the user in distinguishing applications that have been hidden from applications that have not been hidden, the processor 20 may control the display screen 30 to display a second icon corresponding to the target application. The second icon is different from the first icon. Specifically, the first icon may be changed to the second icon by changing the characters, patterns, shapes, colors, light emission luminance, rotation angles, shades, and the like in the first icon. As shown in fig. 13, in one example, the second icon is added with a light-emitting effect compared to the first icon, so that the user can determine whether the application corresponding to the icon is hidden based on whether the icon displayed in the display screen 30 has the light-emitting effect.

Referring to fig. 14, in some embodiments, the application control method further includes:

084: determining a target application to be unhidden among the plurality of hidden applications according to a first input of a user; and

085: the target application is unhidden according to a second input of the user, and the display screen 30 displays the target application in the normal mode after the target application is unhidden.

Referring back to fig. 2, in some embodiments, step 083 and step 085 may be implemented by processor 20. That is, the processor 20 is further configured to determine a target application to be unhidden among the plurality of hidden applications according to a first input of the user, and unhidge the target application according to a second input of the user. After the target application is unhidden, the display screen 30 displays the target application in the normal mode.

The user may trigger the electronic device 100 to enter the hidden application setting mode by entering a plurality of fingerprints on the electronic device 100. In the hidden application setting mode, the user can cancel an application that has been hidden. Specifically, please refer to fig. 15 and 16, in the normal mode, the user inputs the fingerprint data of a plurality of fingers on the electronic device 100, and after the processor 20 determines that the fingerprint data of the plurality of fingers matches with the plurality of fingerprint templates, the processor 20 controls the electronic device 100 to enter the hidden application setting mode. In the hidden application setting mode, the user may long-press (i.e., first input) a certain hidden application, and after detecting the long-press operation of the user, the display screen 30 determines the application long-pressed by the user as a target application to be hidden, and displays options such as "application information", "hidden cancellation", and the like at a peripheral position of the target application for the user to select. After the user clicks (i.e., the second input) "unhide", the processor 20 controls the display screen 30 to unhide the target application. Specifically, when the electronic device 100 exits the hidden application setting mode, that is, the electronic device 100 is in the normal mode, the display screen 30 displays the target application which is unhidden. In this way, the unhidking of the target application which is already hidden can be realized. And after the target application cancels the hiding, the icon corresponding to the target application is changed from the second icon to the first icon. As shown in fig. 16, the first icon has no light emitting effect compared to the second icon.

In some embodiments, as shown in fig. 3, 13, 15 and 16, the processor 20 may further control the display screen 30 to display a first background interface in the normal mode and a second background interface in the hidden application setting mode. The first background interface is different from the second background interface, and specifically, the first background interface may be changed into the second background interface by changing the text, pattern, color, light-emitting brightness, and the like in the first background interface, so that it is convenient for a user to distinguish whether the electronic device 100 is currently in the normal mode or the hidden application setting mode.

As mentioned above, the fingerprint recognition module 10 can be a capacitive fingerprint module 12, an optical fingerprint module 15, or an ultrasonic fingerprint module.

Referring to fig. 17, in one example, the fingerprint recognition module 10 is a capacitive fingerprint module 12. The electronic device 100 further comprises a cover plate 40. Along the light emitting direction of the display screen 30 (integrated with the display and touch functions), the display screen 30, the capacitive fingerprint module 12 and the cover plate 40 are sequentially stacked. The capacitive fingerprint module 12 and the cover plate 40 are bonded together through an optical adhesive layer 50, and the thickness of the optical adhesive layer 50 is 0.05 mm-0.01 mm. The capacitive fingerprint module 12 includes a substrate and a plurality of sensors (not shown) arranged in an array for forming capacitance with the surface of a finger, the sensors are fabricated on the substrate by using a Thin Film Transistor (TFT) process, and the sensors may be made of a transparent material, such as indium tin oxide. When the user put the finger on apron 40, the surface of finger forms the electric capacity with a plurality of sensors in capacitanc fingerprint module 12 respectively, and the capacitance value of different electric capacities can be different along with the difference of the crest and the trough of fingerprint, and capacitanc fingerprint module 12 can form the fingerprint image according to the capacitance value of a plurality of electric capacities. Capacitive fingerprint module 12 is arranged below cover plate 40 in the present application, and then the accepting hole for placing the capacitive fingerprint does not need to be set up in the display area of electronic equipment 100, is favorable to promoting electronic equipment 100's screen to account for than. Moreover, the sensor of the capacitive fingerprint module 12 is made of transparent materials, light emitted by the display screen 30 cannot be shielded by the sensor, and the display of the display screen 30 can be prevented from being influenced.

Referring to fig. 18, in another example, the fingerprint recognition module 10 is an optical fingerprint module 15. The optical fingerprint module 15 includes a photosensitive chip 150, and the photosensitive chip 150 includes a substrate 151 and a plurality of photosensitive pixel units 152 arranged on the substrate 151. The substrate 151 may be made of glass or a flexible polyimide material, and the light sensing pixel unit 152 may be fabricated on the substrate 151 using a TFT process. The optical fingerprint module 15 uses a display screen 30 (e.g., an OLED display screen) as a light source. During the fingerprint inputting process, the display screen 30 emits light, the light emitted by the display screen 30 reaches the surface of the finger and is reflected, and the reflected light can be received by the photosensitive pixel unit 152. The light reflected by the peaks and the valleys has different reflection amounts, and the plurality of photosensitive pixel units 152 can receive the light with different reflection amounts. The optical fingerprint module 15 can form a fingerprint image according to the light received by the plurality of photosensitive pixel units 152.

Specifically, along the light emitting direction of the display screen 30, the optical fingerprint module 15, the display screen 30, and the cover plate 40 are stacked in sequence. Place optical fingerprint module 15 in display screen 30 below, can promote the screen of electronic equipment 100 and account for than. The display screen 30 includes a display surface 31 facing the user and a back surface 32 opposite the display surface 31. A substrate 151 is stacked on a side of the display screen 30 near the back surface 32, and a plurality of light-sensing pixel units 152 are disposed on a side of the substrate 151 facing the display screen 30. The optical fingerprint module 15 further comprises a collimating layer 153. The collimating layer 153 is located on a side of the back surface 32 away from the display surface 31, and the collimating layer 153 completely covers the photosensitive area of the photosensitive chip 150. The collimating layer 153 can transmit the light reflected by the finger to the photosensitive chip 150 to reduce the interference of stray light, and improve the quality of the fingerprint image acquired by the photosensitive chip 150. The thickness of the collimating layer 153 is 0.3mm to 0.5 mm. The collimating layer 153 includes a first surface 1532 facing the back side 32 and a second surface 1533 opposite the first surface 1532. The light reflected by the finger to the collimating layer 153 is transmitted to the second surface 1533 through the first surface 1532, and is emitted from the second surface 1533 to the photosensitive chip 150, and is focused on the photosensitive chip 150, so that the photosensitive chip 150 can obtain an image of the fingerprint. A first optical glue layer 61 is arranged between the first surface 1532 of the collimating layer 153 and the back surface 32. The first optical adhesive layer 61 can adhere the collimating layer 153 to the display 30, the first optical adhesive layer 61 has high transmittance, and light reflected by a finger can be incident on the photosensitive chip 150 through the first optical adhesive layer 61. A second optical adhesive layer 62 is disposed between the second surface 1533 of the collimating layer 153 and the photosensitive chip 150, the collimating layer 153 is adhered to the photosensitive chip 150 by the second optical adhesive layer 62, the second optical adhesive layer 62 also has a high transmittance, and light reflected by a finger can sequentially penetrate through the first optical adhesive layer 61 and the second optical adhesive layer 62 and be incident on the photosensitive chip 150.

Illustratively, the collimating layer 153 has a plurality of through holes 1531 formed thereon, and the plurality of through holes 1531 are used for focusing the light reflected by the finger on the light sensing chip 150. The plurality of through holes 1531 penetrates from the first surface 1532 to the second surface 1533. A plurality of through holes 1531 are arranged in an array on the collimating layer 153, with at least one through hole 1531 for each light-sensitive pixel cell 152, such that at least one through hole 1531 is present to focus light onto a light-sensitive pixel cell 152. Illustratively, each light-sensing pixel cell 152 corresponds to two or more through holes 1531, which prevents light passing through the through holes 1531 from deviating from the light-sensing pixel cell 152. Of course, in other examples, the collimating layer 153 may also be a convex lens, a concave lens, a combination of a convex lens and a concave lens, and the like.

Further, the fingerprint identification module 10 further includes an infrared filter 154, the infrared filter 154 is attached to one side of the collimating layer 153 away from the photosensitive chip 150, and the infrared filter 154 is used for filtering out infrared rays. In this way, each photosensitive pixel unit 152 can only receive visible light, and interference of infrared light to fingerprint image acquisition can be avoided.

Referring to FIG. 19, the present application also provides a non-transitory computer readable storage medium 200 containing computer readable instructions.
