Description

Fingerprint identification device, method, terminal and storage medium

Technical field

This disclosure relates to but is not limited to mobile communication technology.

Background technique

With the development of technology, more and more mobile terminals, such as smart phones, tablet computers, and smart wearable devices, are equipped with fingerprint recognition modules. As an effective security mechanism, fingerprint identification can not only be used to unlock and wake up mobile terminals, but also can be extended to encrypt applications or files. In addition, it can also be applied to mobile payment and account login. Because of its convenience, high speed and high security, fingerprint recognition is widely used.

With the promotion of full-screen terminals, traditional fingerprint implementation methods, such as rear, side, and front fingerprint modules, require holes in the rear or side appearance of the mobile terminal or holes in the front and bottom of the terminal, which affects screen occupation In contrast, this has become a limitation of the innovative design of mobile terminals, which in turn affects the improvement of user experience. At the same time, a separate fingerprint module increases the number and cost of assembly components of the mobile terminal. The technology of fingerprints under the screen came into being.

Among the more popular off-screen fingerprint schemes, more are optical fingerprint and ultrasonic fingerprint schemes. Optical fingerprints are mostly used in OLED screens, but they are not suitable for LCDs with a huge market volume. The limitation of ultrasonic fingerprints is that the penetration distance is limited. After placing the screen, the screen and the glass cover are covered on the top. The penetration effect needs to be improved.

detailed description

The technical solution of the present disclosure will be described in detail below in conjunction with the drawings and embodiments.

FIG. 1 is a schematic diagram of a terminal interface of fingerprint recognition according to an embodiment of the present disclosure. As shown in FIG. 1, the display area of the touch screen of the terminal is called an active display area area (Active Area, AA). The fingerprint sensor array is integrated on the touch screen, and the area of the fingerprint sensor array occupies only a very small area on the touch screen. The fingerprint sensor is on the front of the terminal and can be integrated on the touch screen. The touch screen may be a capacitive screen, and the fingerprint sensor may be a capacitive fingerprint sensor. The ridges and valleys of human fingers have a very small size of about 300 μm to 500 μm, fingerprint recognition requires high accuracy, and the fingerprint recognition electrode lines of the fingerprint sensor array are very dense. Because the outgoing wires of the touch electrode wires of the touch screen in the frame area outside the AA area are already tight, it cannot accommodate a large number of fingerprint recognition electrode wires. The outgoing wires in the limited space of the frame area outside the AA area of the touch screen are connected to the processing unit, the frame area outside the AA area of the touch screen Same as the touch screen frame.

In general, the terminal may be various types of devices with information processing capabilities during the implementation process. For example, the terminal may include a mobile phone, a tablet computer, and a smart wearable device.

Based on the above structural layout of the terminal, various embodiments of the disclosed device and method are proposed.

FIG. 2 is a schematic diagram of a composition structure of a fingerprint recognition device according to an embodiment of the present disclosure. As shown in FIG. 2, the device 200 is applied to a terminal and includes: a fingerprint sensor array 201, a touch module 202 and an application processor 203. The fingerprint sensor array 201 is used to collect fingerprint feature segment information, and includes at least one set of fingerprint identification receiving electrode lines and at least one set of fingerprint identification transmitting electrode lines. Any group of fingerprint identification receiving electrode lines is disposed between two adjacent touch receiving electrode lines of the touch module 202, extending along the direction of the touch receiving electrode lines and arranged in parallel. Any group of fingerprint identification emission electrode lines is disposed between two adjacent touch emission electrode lines of the touch module 202, extending along the direction of the touch emission electrode lines and arranged in parallel. The application processor 203 is used for splicing and synthesizing information of a plurality of fingerprint feature segments collected by the fingerprint sensor array 201 into recognizable fingerprint information.

It should be noted that the embodiment shown in FIG. 2 is that the fingerprint recognition receiving electrode line and the fingerprint recognition transmitting electrode line of the fingerprint sensor array 201 are partially arranged on the touch screen to occupy a small area, so as to rarely occupy the outer space of the outer border of the touch screen AA area . Since only a limited amount of fingerprint feature segment information can be collected in each collection action, during the sliding operation on the touch screen, fingerprint feature segment information is collected multiple times at intervals, and the fingerprint feature segment information is processed and spliced by the application processor 203 Synthesized into identifiable fingerprint information. The application processor 203 compares the identifiable fingerprint information with the fingerprint information pre-stored in the memory of the terminal, and performs unlocking of the terminal or other corresponding operations. In this way, the use of a small number of fingerprint identification receiving electrode lines and fingerprint identification transmitting electrode lines can reduce the occupation of the outer space of the outer border of the touch screen AA area, which effectively solves the technical difficulty of integrating capacitive fingerprints on the capacitive touch screen, that is, a small amount of fingerprint identification The electrode line and the fingerprint identification transmitting electrode line are combined with the touch receiving electrode line and the touch transmitting electrode line, and only a small amount of wires can be added to the limited frame area of the touch screen to realize fingerprint recognition.

For the embodiment shown in FIG. 2, it should be noted that because fingerprints require higher accuracy than touch, it is necessary to arrange a group of encryption on the basis of the original touch receiving electrode lines and touch transmitting electrode lines of the capacitive touch screen Or multiple sets of fingerprint identification receiving electrode lines and fingerprint identification transmitting electrode lines to form a fingerprint sensor array 201.

FIG. 3 is a schematic diagram of the distribution of fingerprint transmission electrode lines, fingerprint reception electrode lines, touch transmission electrode lines, and touch reception electrode lines according to an embodiment of the present disclosure. As shown in FIG. 3, FTx is a fingerprint transmission electrode line 301, FRx is a fingerprint reception electrode line 302, PTx is a touch transmission electrode line 303, and PRx is a touch reception electrode line 304. The FTx fingerprint transmitting electrode line 301 and the PTx touch transmitting electrode line 303 are used to transmit electrical signals, and the FRx fingerprint receiving electrode line 302 and PRx touch receiving electrode line 304 are used to receive electrical signals. A set of FTx fingerprint emission electrode lines 301 may be disposed between any two adjacent PTx touch emission electrode lines 303, and each FTx fingerprint emission electrode line 301 extends in the direction of the PTx touch emission electrode line 303 and is arranged parallel to each other. A set of FRx fingerprint receiving electrode lines 302 may be disposed between any two adjacent PRx touch receiving electrode lines 304, and each FRx fingerprint receiving electrode line 302 extends in the direction of the PRx touch receiving electrode lines 304 and is arranged parallel to each other.

As shown in FIG. 3, the FTx fingerprint transmitting electrode line 301 according to an embodiment of the present disclosure may include a group of FTx fingerprint transmitting electrode lines (FTx1, FTx2, FTx3, FTx4), and the group of FTx fingerprint transmitting electrode lines (FTx1, FTx2, FTx3, FTx4) are arranged between the PTx1, PTX2 touch emission electrode lines 303. The FRx fingerprint receiving electrode wire 302 according to an embodiment of the present disclosure may include five sets of FRx fingerprint receiving electrode wires (FRx11, FRx12, FRx13, FRx14), (FRx21, FRx22, FRx23, FRx24), (FRx31, FRx32, FRx33, FRx34 ), (FRx41, FRx42, FRx43, FRx44), (FRx51, FRx52, FRx53, FRx54), the five groups of FRx fingerprint receiving electrode lines are arranged in this order: PRx1 touch receiving electrode line 304 and PRx2 touch receiving electrode line 304 Between PRx2 touch receiving electrode line 304 and PRx3 touch receiving electrode line 304, between PRx3 touch receiving electrode line 304 and PRx4 touch receiving electrode line 304, PRx4 touch receiving electrode line 304 and PRx5 touch receiving Between electrode lines 304, and between PRx5 touch receiving electrode lines 304 and PRx6 touch receiving electrode lines 304.

It should be noted that the PTx touch transmitting electrode line 303 and the FTx fingerprint transmitting electrode line 301 can be on the same layer, and the PRx touch receiving electrode line 304 and the FRx fingerprint receiving electrode line 302 can be on the same layer and are arranged between the two layers of lines There is an insulating layer. Because the terminal design tends to be a narrow bezel design of the screen, the large number of touch electrode wires will make the outlet space of the bezel area on both sides of the AA area of the touch screen very tight. The technical solution uses a small amount of fingerprint identification receiving electrode lines and fingerprint identification transmitting electrode lines to form a fingerprint sensor array that can identify fingerprint feature segment information, so as to reduce the occupation of the outgoing space of the border area on both sides of the AA area of the touch screen.

The present disclosure does not limit the number and arrangement of FTx fingerprint transmitting electrode lines 301, FRx fingerprint receiving electrode lines 302, PTx touch transmitting electrode lines 303, and PRx touch receiving electrode lines 304.

FTx fingerprint transmitter electrode line 301 and FRx fingerprint receiver electrode line 302 can be independent of PTx touch transmitter electrode line 303 and PRx touch receiver electrode line 304, or according to the situation with some PTx touch transmitter electrode line 303 and PRx touch receiver The electrode lines 304 are multiplexed, and they can be switched using switches or other methods.

According to an embodiment of the present disclosure, it can be arranged in a combination of a small number of FTx fingerprint transmitting electrode lines 301 and a large number of FRx fingerprint receiving electrode lines 302, and the sliding operation direction is perpendicular to the FTx fingerprint transmitting electrode lines 301 or crosses at an angle; or A large number of FTx fingerprint transmitting electrode wires 301 and a small number of FRx fingerprint receiving electrode wires 302 are arranged in a combined manner.

According to the embodiments of the present disclosure, the number of FTx fingerprint transmitting electrode lines 301 and FRx fingerprint receiving electrode lines 302 can be appropriately increased, and sufficient identifiable fingerprint characteristic information can be collected in a single operation during a touch operation, thereby simplifying the sliding operation.

For the embodiment shown in FIG. 2, the application processor 203 is also used to compare the identifiable fingerprint information with the pre-stored fingerprint information, when the similarity between the identifiable fingerprint information and the pre-stored fingerprint information reaches a preset threshold At this time, the application processor 203 can perform preset operations, including terminal unlocking, designated application unlocking, designated on-screen area unlocking, designated file unlocking, mobile payment, and account login.

For the embodiment shown in FIG. 2, the touch module 202 is used to monitor touch operations and sliding operations on the area of the fingerprint sensor array 201; the fingerprint sensor array 201 is used to collect fingerprint feature segment information during the touch operations and sliding operations.

According to an embodiment of the present disclosure, the fingerprint sensor array 201 is used to collect multiple pieces of fingerprint feature information according to a preset time interval or a preset sliding distance interval during a sliding operation.

It should be noted that because the collected information of a single fingerprint feature segment is very limited, multiple fingerprint feature segment information can be collected according to a preset time interval or a preset sliding distance interval, so as to be able to splice and synthesize identifiable fingerprint information .

According to an embodiment of the present disclosure, the fingerprint sensor array 201 is used to collect one or more fingerprint feature segment information when the touch module 202 detects a touch operation or a sliding operation on the area of the fingerprint sensor array 201.

According to an embodiment of the present disclosure, the fingerprint identification transmitting electrode lines and fingerprint identification receiving electrode lines of the fingerprint sensor array 201 may be multiplexed with the touch emitting electrode lines and touch receiving electrode lines of the touch module 202, respectively.

It should be noted that the area of the fingerprint sensor array 201 can be identified on the touch screen by: identifying the corresponding positions on the left and right side borders of the touch screen; or identifying the corresponding positions on the appearance structure of the terminal; or marking the touch screen as appearance Transparent reflective visible lines; or without considering the impact of power consumption, when a touch or fingerprint is detected in the specified area of the terminal, it can be lit in full screen or partially and the specified area is displayed on the screen to prompt the user to move the finger direction.

Based on the same inventive concept as the foregoing embodiment, FIG. 4 is a schematic flowchart of an implementation process of a fingerprint recognition method according to an embodiment of the present disclosure. As shown in FIG. 4, the method is applied to a fingerprint recognition device including a fingerprint sensor array, and includes steps S401 and S402.

In step S401, when a sliding operation on the area of the fingerprint sensor array is monitored, fingerprint feature segment information during the sliding operation is collected by the fingerprint sensor array.

In step S402, the fingerprint feature segment information is spliced and synthesized into recognizable fingerprint information according to a preset splicing and synthesis strategy.

According to an embodiment of the present disclosure, after splicing and synthesizing fingerprint feature segment information into recognizable fingerprint information according to a preset splicing and synthesis strategy, the method may further include: performing recognizable fingerprint information with pre-stored fingerprint information In contrast, when the similarity between the identifiable fingerprint information and the pre-stored fingerprint information reaches a preset threshold, a preset operation is performed, where the preset operation may include terminal unlocking, designated application unlocking, designated on-screen area unlocking, and designated file Unlock, mobile payment, account login.

According to an embodiment of the present disclosure, when the sliding operation on the area of the fingerprint sensor array is monitored, the step of the fingerprint sensor array collecting fingerprint feature segment information during the sliding operation may include: the fingerprint sensor array according to a preset time interval or The preset sliding distance interval collects information of multiple fingerprint feature fragments.

According to an embodiment of the present disclosure, before the swipe operation on the area of the fingerprint sensor array is monitored, before the fingerprint sensor array collects fingerprint feature segment information during the swipe operation, the method may further include: when the fingerprint sensor array is detected When there is a touch operation on the area, the fingerprint sensor array collects a piece of fingerprint feature information.

The technical solutions according to the embodiments of the present disclosure will be described below through specific examples. FIG. 5 is a schematic flowchart of an implementation of a fingerprint recognition method according to an embodiment of the present disclosure. As shown in FIG. 5, the fingerprint recognition method according to an embodiment of the present disclosure may include steps S501 to S509.

In step S501, the fingerprint sensor array is in a standby polling monitoring (ie, standby monitoring) state.

It should be noted that the fingerprint sensor array is used to collect fingerprint feature segment information.

In step S502, the touch module determines whether there is a touch operation on the designated area on the touch screen of the terminal.

It should be noted that the designated area is the area of the fingerprint sensor array on the touch screen. When the fingerprint sensor array of the terminal is in the standby polling monitoring state, the touch module of the terminal scans the designated area to determine whether there is a touch operation, and if a touch operation is detected (ie, it is determined that there is a touch operation), go to step S503 If the touch operation is not monitored (that is, it is determined that there is no touch operation), it returns to step S501.

In step S503, the fingerprint sensor array collects the first fingerprint feature segment information.

It should be noted that when the touch module detects the touch operation, the fingerprint sensor array starts to collect the first fingerprint feature segment information, and passes the collected first fingerprint feature segment information to the application processor of the terminal.

In step S504, it is determined whether there is a sliding operation in a designated area on the touch screen of the terminal.

It should be noted that, because the first fingerprint feature segment collected by the fingerprint sensor array of the terminal has a small amount of information, which is insufficient for fingerprint recognition, in order to obtain more fingerprint feature segment information, it is necessary to determine whether there is a sliding operation. According to an embodiment of the present disclosure, if the touch module determines that the position of the touch operation has changed, it may be determined that there is a sliding operation. According to another embodiment of the present disclosure, if the fingerprint feature segment information collected by the fingerprint sensor array on the designated area changes, the touch module may determine that there is a sliding operation. If a sliding operation is detected (ie, it is determined that there is a sliding operation), then go to step S505; if no sliding operation is detected (ie, it is determined that there is no sliding operation), then return to step S501.

In step S505, the fingerprint sensor array collects multiple pieces of fingerprint feature segment information during the sliding operation.

It should be noted that when a sliding operation is detected, the fingerprint sensor array of the terminal continuously collects information of multiple fingerprint feature segments at a fixed time interval or a fixed sliding distance interval, and transmits the collected fingerprint feature segment information to the terminal Application processor.

In step S506, the application processor of the terminal splices multiple pieces of fingerprint feature segment information into recognizable fingerprint information.

It should be noted that the application processor of the terminal splices multiple pieces of fingerprint feature information transmitted by the fingerprint sensor array with a preset algorithm to synthesize it into recognizable fingerprint information. During stitching and synthesis, multiple fingerprint feature segment information includes the collected first fingerprint feature segment information

In step S507, the application processor of the terminal compares the identifiable fingerprint information with the pre-stored fingerprint information.

It should be noted that the application processor of the terminal reads the pre-stored fingerprint information from the terminal's memory, compares the identifiable fingerprint information with the read pre-stored fingerprint information, and determines the identifiable fingerprint information and the pre-stored Whether the degree of similarity of the fingerprint information reaches a preset threshold. If the preset threshold is reached, it is determined to be a legitimate user operation, then go to step S508; if the preset threshold is not reached, it is determined to be an illegal user operation, then go to step S509.

In step S508, a preset operation after successful fingerprint recognition (ie, determined to be a legal user operation) is performed.

It should be noted that, when judged as a legitimate user operation, subsequent preset operations are performed, such as terminal unlocking, designated application unlocking, designated on-screen area unlocking, designated file unlocking, mobile payment, account login, etc.

In addition, according to an embodiment of the present disclosure, in the case of a black screen, after successful fingerprint recognition, a certain function of the terminal, such as taking pictures, playing music, and alarming, can be quickly started.

In step S509, the terminal prompts that fingerprint recognition has failed.

It should be noted that, when it is determined that the operation is illegal, the terminal prompts the user that fingerprint recognition has failed. The prompting method may be to turn on the vibration motor for pulse vibration or a perceptible prompt, and then return to step S501.

Based on the same inventive concept as the foregoing embodiments, the technical solutions according to the embodiments of the present disclosure will be described below through specific examples. 6 is a schematic diagram of an implementation process of a fingerprint recognition method according to an embodiment of the present disclosure. As shown in FIG. 6, the fingerprint recognition method according to an embodiment of the present disclosure may include steps S601 to S607.

In step S601, the touch module of the terminal is in a standby monitoring state.

In step S602, the touch module of the terminal determines whether there is a touch operation and a slide operation on the designated area on the touch screen.

It should be noted that the touch module of the terminal is in a designated area on the touch screen and is in a polling monitoring (ie, standby monitoring) state, and the designated area is the area of the fingerprint sensor array on the touch screen.

It should be noted that, in the polling monitoring state, the touch module of the terminal scans the designated area to determine whether there is a touch operation and a sliding operation, and if the touch operation and the sliding operation are detected (that is, the touch operation and the sliding operation are determined) Then, go to step S603, and if touch operation and sliding operation are not monitored (that is, it is judged that there is no touch operation and sliding operation), then return to step S601.

In step S603, the fingerprint sensor array collects multiple pieces of fingerprint feature segment information during the sliding operation.

It should be noted that when the touch module of the terminal detects touch operation and sliding operation in the specified area, the fingerprint sensor array of the terminal continuously collects multiple pieces of fingerprint feature information at a fixed time interval or fixed sliding distance, and The collected fingerprint feature segment information is passed to the application processor of the terminal.

In step S604, the application processor of the terminal splices multiple pieces of fingerprint feature segment information into recognizable fingerprint information.

It should be noted that the application processor of the terminal splices multiple pieces of fingerprint feature information transmitted by the fingerprint sensor array of the terminal with a preset algorithm to synthesize it into identifiable fingerprint information.

In step S605, the application processor of the terminal compares the identifiable fingerprint information with the pre-stored fingerprint information.

It should be noted that the application processor of the terminal reads the pre-stored fingerprint information from the terminal's memory, compares the identifiable fingerprint information with the read pre-stored fingerprint information, and determines that the identifiable fingerprint information and the pre-stored fingerprint information Whether the similarity degree of fingerprint information reaches a preset threshold. If the preset threshold is reached, it is determined to be a legal user operation, and then go to step S606; if the preset threshold is not reached, it is determined to be an illegal user operation, and then go to step S607.

In step S606, a preset operation after successful fingerprint recognition (ie, judged as a legal user operation) is performed.

In addition, preferably, in the case of a black screen, after successful fingerprint recognition, a certain function of the terminal, such as taking pictures, playing music, and alarming, can be quickly started.

In step S607, the terminal prompts that fingerprint recognition has failed.

It should be noted that, when it is judged as an illegal user operation, the terminal prompts the user that fingerprint recognition has failed. The prompting method may be to turn on the vibration motor for pulse vibration or a perceptible prompt, and then return to step S601.
