Detailed Description
The technical solution of the present invention is further elaborated below with reference to the drawings and the embodiments.
Fig. 1 is a schematic diagram of a terminal interface for fingerprint identification according to an embodiment of the present invention, and as shown in fig. 1, a display Area of a touch screen of the terminal is called a touch screen AA Area (Active Area). The fingerprint sensor array is integrated on the touch screen, and the area of the fingerprint sensor array only occupies a tiny area on the touch screen, wherein the fingerprint sensor is arranged on the front face of the terminal and is integrated on the touch screen. The touch screen is a capacitive screen, and the fingerprint sensor is a capacitive type. The ridges and valleys of a human finger have very small sizes of about 300 to 500 μm, the fingerprint identification requirement precision is very high, the fingerprint identification electrode lines of the fingerprint sensor array are very dense, and the touch electrode lines of the touch screen cannot accommodate a large number of fingerprint identification electrode lines because the outgoing lines of the touch electrode lines outside the AA area are already very short. The fingerprint identification receiving electrode line, the fingerprint identification transmitting electrode line, the touch receiving electrode line and the touch transmitting electrode line are connected to the processing unit in a limited space of an AA area outer frame of the touch screen, and the AA area outer frame is the same as the touch screen frame.
Generally, the terminal may be various types of devices with information processing capability in the implementation process, for example, the terminal may include a mobile phone, a tablet computer, a smart wearable device, and the like.
Various embodiments of the apparatus and method of the present invention are presented based on the structural layout of the terminal described above.
Example one
Fig. 2 is a schematic diagram of a configuration of a fingerprint identification apparatus according to an embodiment of the present invention, and as shown in fig. 2, the apparatus 200 is applied to a terminal, and the apparatus 200 includes: a fingerprint sensor array 201, a touch module 202 and an AP application processor 203; wherein the content of the first and second substances,
the fingerprint sensor array 201 is used for collecting fingerprint characteristic fragment information and comprises at least one group of fingerprint identification receiving electrode wires and at least one group of fingerprint identification transmitting electrode wires;
any one group of the fingerprint identification receiving electrode lines is arranged between two adjacent touch receiving electrode lines of the touch module 202 and arranged in parallel along the direction of the touch receiving electrode lines;
any one group of the fingerprint identification emission electrode lines is arranged between two adjacent touch emission electrode lines of the touch module 202 and arranged in parallel along the direction of the touch emission electrode lines;
the AP application processor 203 is configured to splice and synthesize a plurality of pieces of fingerprint feature information acquired by the fingerprint sensor array 201 into identifiable fingerprint information.
For the technical scheme shown in fig. 2, it should be noted that, in the technical scheme, the fingerprint identification receiving electrode lines and the fingerprint identification transmitting electrode lines of the fingerprint sensor array 201 are locally arranged on the touch screen, and the areas of the fingerprint identification receiving electrode lines and the fingerprint identification transmitting electrode lines are small, so that the very tight AA area outer frame outgoing line space is occupied less, and only limited fingerprint feature fragment information can be acquired in each acquisition action; in the sliding operation process on the touch screen, fingerprint characteristic fragment information is acquired at intervals for multiple times, processed by the AP application processor 203 and spliced to form identifiable fingerprint information; then the identifiable fingerprint information is compared with fingerprint information prestored in a memory of the terminal, and terminal unlocking or other corresponding operations are executed; therefore, the occupation of the outgoing line space of the frames on two sides of the AA area of the touch screen is reduced by using a small number of fingerprint identification receiving electrode lines and fingerprint identification transmitting electrode lines, the technical difficulty of integrating capacitive fingerprints on the capacitive touch screen is effectively solved, the small number of fingerprint identification receiving electrode lines and fingerprint identification transmitting electrode lines are combined with the touch receiving electrode lines and the touch transmitting electrode lines, and the fingerprint identification can be realized only by adding a small number of outgoing lines in the limited frame area of the touch screen.
The AP Application Processor 203 is an Application Processor.
For the technical solution shown in fig. 2, it should be noted that, because the precision required by the fingerprint is higher than that required by the touch, on the basis of the original touch receiving electrode lines and touch transmitting electrode lines of the capacitive touch screen, one or more groups of fingerprint identification receiving electrode lines and fingerprint identification transmitting electrode lines are arranged in an encrypted manner to form the fingerprint sensor array 201.
Fig. 3 is a schematic distribution diagram of a fingerprint transmitting electrode line, a fingerprint receiving electrode line, a touch transmitting electrode line and a touch receiving electrode line according to an embodiment of the present invention, as shown in fig. 3, FTx is the fingerprint transmitting electrode line 301, FRx is the fingerprint receiving electrode line 302, PTx is the touch transmitting electrode line 303, and PRx is the touch receiving electrode line 304. The FTx fingerprint transmitting electrode lines 301 and the PTx touch transmitting electrode lines 303 are responsible for transmitting electric signals, and the FRx fingerprint receiving electrode lines 302 and the PRx touch receiving electrode lines 304 are responsible for receiving electric signals. A group of FTx fingerprint transmitting electrode lines 301 may be disposed between any two PTx touch transmitting electrode lines 303, and the FTx fingerprint transmitting electrode lines 301 are arranged in parallel along the direction of the PTx touch transmitting electrode lines 303. A group FRx of fingerprint receiving electrode lines 302 may be disposed between any two adjacent PRx touch receiving electrode lines 304, and FRx of fingerprint receiving electrode lines 302 are arranged in parallel along the direction of the PRx 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 are on the same layer, the PRx touch receiving electrode line 304 and the FRx fingerprint receiving electrode line 302 are on the same layer, and an insulating layer is arranged between the two layers of lines. Because the terminal design tends to narrow frame on the screen, and the number of touch electrode wires is large, the wiring space of the frame areas at two sides of the AA area of the touch screen is very short.
Preferably, the number and arrangement of the FTx fingerprint transmitting electrode lines 301 and FRx fingerprint receiving electrode lines 302, PTx touch transmitting electrode lines 303, and PRx touch receiving electrode lines 304 are not limited.
Preferably, the FTx fingerprint transmitting electrode lines 301 and FRx and the fingerprint receiving electrode lines 302 may be independent of the PTx touch transmitting electrode lines 303 and the PRx touch receiving electrode lines 304, or may be multiplexed with a part of the PTx touch transmitting electrode lines 303 and the PRx touch receiving electrode lines 304 according to the circumstances, and the multiplexing may be implemented by switching using a switch or other manners.
Preferably, the FTx fingerprint transmission electrode line comprises a small number of FTx fingerprint transmission 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 transmission electrode lines 301 or intersects at a certain angle; or may be composed of a large number of FTx fingerprint transmitting electrode lines 301 and a small number of FRx fingerprint receiving electrode lines 302.
Preferably, the number of the FTx fingerprint transmitting electrode lines 301 and FRx and the number of the fingerprint receiving electrode lines 302 can be increased appropriately, so that sufficient identifiable fingerprint characteristic information can be acquired at a single time during touch operation, and the sliding operation is simplified.
For the technical solution shown in fig. 2, the AP application processor 203 is further configured to compare the recognizable fingerprint information with preset fingerprint information, and execute a preset operation when characteristic information in the recognizable fingerprint information reaches a preset threshold, where the preset operation includes terminal unlocking, designated application unlocking, designated on-screen area unlocking, designated file unlocking, mobile payment, and account login.
In the above solution, the touch module 202 is configured to monitor a touch operation and a sliding operation on an area of the fingerprint sensor array 201; the fingerprint sensor array 201 is configured to collect fingerprint feature fragment information during the sliding operation.
Then, preferably, the fingerprint sensor array 201 is configured to collect a plurality of pieces of fingerprint feature information according to a preset time interval or a preset sliding distance interval during the sliding operation.
It should be noted that, because the collected single fingerprint feature segment information is very limited, a plurality of fingerprint feature segment information are collected at preset time intervals or preset sliding distance intervals of the designated area of the touch screen, so that the identifiable fingerprint information can be combined by splicing.
Preferably, the fingerprint sensor array 201 is configured to acquire fingerprint feature fragment information when it is monitored that the touch operation exists in an area of the fingerprint sensor array 201.
Preferably, the fingerprint identification transmitting electrode lines and the fingerprint identification receiving electrode lines of the fingerprint sensor array 201 are multiplexed with the touch control transmitting electrode lines and the touch control receiving electrode lines of the touch control module 202.
It should be noted that, the area of the fingerprint sensor array 201 on the touch screen is identified by the following method: the marks can be marked at the corresponding positions of the frames at the left side and the right side of the touch screen; or the corresponding position mark on the terminal appearance structure; or the touch screen is marked by lines with transparent and reflective appearance; or under the condition of not considering the influence of power consumption, when the terminal specified area detects touch or fingerprints, the terminal can be lightened in a full screen or a partial mode, the specified area is displayed on the screen, and the moving direction of the finger of the user is prompted.

Based on the same inventive concept of the foregoing embodiments, fig. 4 is a schematic flow chart of an implementation of the method for fingerprint identification according to the embodiments of the present invention, and as shown in fig. 4, the method is applied to a device for fingerprint identification, where the device includes: a fingerprint sensor array, the method comprising:
step S401, when the sliding operation on the area of the fingerprint sensor array is monitored, the fingerprint sensor array collects fingerprint characteristic fragment information in the sliding operation process;

Preferably, before the fingerprint sensor array acquires fingerprint feature fragment information during the sliding operation when the sliding operation on the area of the fingerprint sensor array is monitored, the method further includes:
and when the fingerprint sensor array monitors that touch operation exists in the area of the fingerprint sensor array, acquiring fingerprint characteristic fragment information.
An embodiment of the present embodiment describes technical solutions of the foregoing embodiments by specific examples, and fig. 5 is a schematic flow chart of an implementation of a fingerprint identification method according to an embodiment of the present invention, as shown in fig. 5, specifically including:
step S501, the fingerprint sensor array is in a standby polling monitoring state.
It should be noted that the fingerprint sensor array is used for collecting fingerprint feature fragment information.
Step S502, the fingerprint sensor array is arranged in a designated area on a touch screen of the terminal to judge whether touch operation exists.
It should be noted that the designated area is an area of the fingerprint sensor array on the touch screen; and the fingerprint sensor array of the terminal scans whether a touch operation exists in a designated area in a polling state, if the touch operation is monitored, the process goes to the step S503, and if the touch operation is not monitored, the process returns to the step S501.
In step S503, the fingerprint sensor array collects first fingerprint feature fragment information.
It should be noted that, when the fingerprint sensor array monitors a touch operation, the first fingerprint feature segment information starts to be collected and transmitted to the AP application processor of the terminal.
And step S504, judging whether a sliding operation exists in a designated area on a touch screen of the terminal.
It should be noted that, because the amount of information of the first fingerprint feature fragment acquired by the fingerprint sensor array of the terminal is small, it is not enough to perform fingerprint identification, and to acquire more fingerprint feature fragment information, it is necessary to further determine whether there is a sliding operation. If the touch module judges that the position of the sliding operation is changed, the sliding operation can be judged; if the fingerprint characteristic information collected by the fingerprint sensor array on the designated area is changed, the sliding operation can be judged. If the sliding operation is monitored, processing goes to step S505; if the sliding operation is not monitored, the process returns to step S501.
And step S505, the fingerprint sensor array collects a plurality of pieces of fingerprint characteristic information in the sliding operation process.
It should be noted that, when the sliding operation is monitored, the fingerprint sensor array of the terminal continuously collects a plurality of pieces of fingerprint feature information at fixed time intervals or fixed sliding distance intervals, and transmits the collected pieces of fingerprint feature information to the AP application processor of the terminal.
Step S506, the AP application processor of the terminal concatenates the multiple pieces of fingerprint feature information into identifiable fingerprint information.
It should be noted that the AP application processor of the terminal concatenates the multiple pieces of fingerprint feature fragment information transmitted back by the fingerprint sensor array by a preset algorithm to synthesize identifiable fingerprint information. When a plurality of pieces of fingerprint characteristic information are spliced and combined, the information comprises the first piece of acquired fingerprint characteristic information
Step S507, the AP application processor of the terminal compares the recognizable fingerprint information with the preset fingerprint information.
It should be noted that the AP application processor of the terminal reads the pre-stored fingerprint information from the memory of the terminal, compares the recognizable fingerprint information with the read pre-stored fingerprint information, and determines whether the characteristic information in the recognizable fingerprint information reaches a preset threshold value. If the preset threshold is reached, the operation is deemed to be a correct operation by a legal user, the processing goes to step S508, and if the preset threshold is not reached, the operation is deemed to be an illegal user, the processing goes to step S509.
Step S508, a preset operation after the fingerprint recognition is successful is performed.
It should be noted that, after the correct operation is determined for the legitimate user, subsequent preset operations are performed, such as terminal unlocking, designated application unlocking, designated on-screen area unlocking, designated file unlocking, mobile payment, account login, and the like.
In addition, preferably, under the condition of a black screen, after the fingerprint identification is successful, some functions of the terminal, such as taking a picture, playing music, alarming and the like, are quickly started.
Step S509: and the terminal prompts that the fingerprint identification fails.
It should be noted that, when it is determined that the operation by the illegal user is failed, the terminal prompts that the fingerprint identification is failed, and the prompting manner may be to turn on a vibration motor to perform pulse vibration or to perform a sensible explicit prompt, and then the process returns to step S501.

Step S602, the touch module of the terminal designates an area on the touch screen, and determines whether there is a touch operation or a sliding operation.
It should be noted that, in the polling monitoring state, the touch module of the terminal scans whether there is a touch operation and a slide operation in the designated area, if the touch operation and the slide operation are monitored, the process goes to step S603, and if the touch operation and the slide operation are not monitored, the process returns to step S601.
Step S603, the fingerprint sensor array collects a plurality of pieces of fingerprint feature information during the sliding operation.
It should be noted that when the touch module of the terminal monitors that there is a touch operation and a sliding operation in the designated area, the fingerprint sensor array of the terminal continuously collects a plurality of pieces of fingerprint feature information at fixed time intervals or at fixed sliding distances, and transmits the collected pieces of fingerprint feature information to the AP application processor of the terminal.
Step S604, the AP application processor of the terminal concatenates the multiple pieces of fingerprint feature information into identifiable fingerprint information.
It should be noted that the AP application processor of the terminal concatenates the multiple pieces of fingerprint feature fragment information transmitted back by the fingerprint sensor array of the terminal by using a preset algorithm, and synthesizes the pieces of fingerprint feature fragment information into identifiable fingerprint information.

It should be noted that the AP application processor of the terminal reads the pre-stored fingerprint information from the memory of the terminal, compares the recognizable fingerprint information with the read pre-stored fingerprint information, and determines whether the characteristic information in the recognizable fingerprint information reaches a preset threshold value; if the preset threshold value is reached, the operation is judged to be correct by a legal user, and the step S606 is carried out; if the preset threshold value is not reached, the operation is regarded as an illegal user operation, and the process goes to execute the step S607.
Step S606, a preset operation after the fingerprint identification is successful is performed.
It should be noted that, after the correct operation is determined for the legitimate user, subsequent preset operations are performed, such as terminal unlocking, designated application unlocking, designated on-screen area unlocking, designated file unlocking, mobile payment, account login, and the like.
In addition, preferably, under the condition of a black screen, after the fingerprint identification is successful, some functions of the terminal, such as taking a picture, playing music, alarming and the like, are quickly started.
In step S607, the terminal prompts that the fingerprint identification fails.
It should be noted that, when it is determined that the operation by the illegal user is performed, the terminal prompts the user that the fingerprint identification fails, and the prompting manner may be to turn on a vibration motor to perform pulse vibration or to perform sensible explicit prompting, and then the process returns to step S601.
