Detailed Description
Reference will now be made in detail to embodiments of the present invention, 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 with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The fingerprint recognition device, the mobile terminal, and the wake-up method of the fingerprint recognition device according to the embodiments of the present invention will be described with reference to the accompanying drawings.
Fig. 1 is a schematic structural diagram of a fingerprint recognition device according to an embodiment of the present invention. As shown in fig. 1, a fingerprint identification device 10 according to an embodiment of the present invention includes: a fingerprint identification chip 100, a plurality of detector areas 200 and a metal ring 300.
Wherein, a plurality of detector sub-regions 200 are disposed on the fingerprint identification chip 100, and the metal ring 300 surrounds the fingerprint identification chip 100. The fingerprint identification chip 100 is used for detecting the number of covered detection subareas 200 after detecting that the metal ring 300 is touched for a first preset time, and if the number is greater than a preset threshold value, the fingerprint identification chip 100 starts fingerprint identification scanning.
Specifically, the metal ring 300 is connected to an emitting pin inside the fingerprint identification chip 100, and is used for not only serving as an emitter of a signal but also performing CSD detection (i.e., capacitance detection), and the plurality of detection sub-regions are artificially set regions on the surface array of the fingerprint identification chip 100 and can be used as a basis for determining the finger coverage area.
More specifically, after the fingerprint identification chip 100 detects that the metal ring 300 is touched for a first preset time, Sub _ area (representing a detection Sub-area) detection is triggered, and the Sub _ area detection is triggered, and it is determined whether the area pressed by the finger reaches an acquisition threshold, that is, whether the number of covered detection Sub-areas 200 detected by the fingerprint identification chip 100 is greater than a preset threshold, and if so, the fingerprint identification scanning function of the fingerprint identification chip 100 is awakened, that is, the fingerprint identification chip 100 performs fingerprint scanning of the whole area, and then performs subsequent work such as fingerprint matching. In addition, if the number of covered detection sub-regions 200 is not greater than the preset threshold, which indicates that there is no valid finger touch, the fingerprint identification chip 100 continues to detect the metal ring 300 until there is no finger touch.
As shown in fig. 2, the fingerprint identification device 10 according to the embodiment of the present invention is applied to a mobile terminal, wherein the fingerprint identification device 10 may be disposed on the front side or the back side of the mobile terminal.
In an embodiment of the present invention, the number of the detection arrays of the fingerprint identification chip 100 is 160 × 80, the number of the detection sub-regions 200 is 16, the arrangement order is as shown in fig. 3, and the size of each detection sub-region is 8 × 8 pixels. The metal ring 300 is scanned every 10ms, and the preset threshold for the number of covered detection sub-regions for starting the full-region scanning is 10.
For example, if the fingerprint identification chip 100 detects that the metal ring 300 is touched 4 times in succession, which means that there is a finger or a conductor touching the fingerprint identification device 10, the fingerprint identification chip 100 needs to further determine whether it is a valid finger touch, so as to trigger the detection sub-area to scan to determine whether there is a real finger press, namely, whether the pressed area meets the requirement is judged, if the number of covered detection subareas 200 reaches the preset threshold value, that is, 10 sub-detection regions 200 are covered by the finger, the finger pressing area is considered to reach the finger scanning threshold, at this time, the fingerprint identification chip 100 will notify the mobile terminal to interrupt the whole region scanning, that is, the fingerprint identification chip 100 starts the fingerprint identification scanning, then matching is carried out, if matching is successful, the mobile terminal is unlocked and the screen is lightened, and the mobile terminal is successfully awakened; if the matching is not successful for many times, the mobile terminal can also light the screen and prompt that the failure times are excessive, and please wait or adopt other unlocking modes such as password unlocking and the like.
In one embodiment of the present invention, the plurality of detector sub-regions 200 are divided into N rows, where N is a positive integer.
In one embodiment of the present invention, each row of detector sub-regions 200 includes M detector sub-regions 200, wherein each adjacent two detector sub-regions in the 1 st to ith detector sub-regions 200 have a first spacing therebetween, each adjacent two detector sub-regions in the i th to jth detector sub-regions 200 have a second spacing therebetween, and each adjacent two detector sub-regions in the j th to mth detector sub-regions 200 have a third spacing therebetween, wherein i is a positive integer less than j, and j is a positive integer less than M.
In one embodiment of the invention, the first and third spacings are equal, and the second spacing is greater than the first spacing.
Specifically, when each row includes M detector sub-regions, that is, the number of columns of detector sub-regions is M, then in each row of detector sub-regions, the spacing (the first spacing, the second spacing, and the third spacing) between every two adjacent detector sub-regions may be set to be a multiple of M according to practical situations, for example, in one specific embodiment, when the fingerprint identification chip 100 is wide, the second spacing may be set to be a multiple of the first spacing.
Of course, in other embodiments, for example, when the fingerprint recognition chip 100 is relatively narrow, the first interval, the second interval, and the third interval may be set to be equal.
In one embodiment of the present invention, the detector sub-region 200 is a rectangle of K × K, and the distance between the detector sub-region 200 and the metal ring 300 is K, where K is a positive integer.
Specifically, taking the detection array shown in fig. 3 as an example, the detection array is 160 × 80, the number of the detection sub-regions 200 is 16, the size of each detection sub-region 200 is 8 × 8(K × K) pixels, and the purpose of setting the detection sub-regions 200 as a rectangle of K × K is as follows: according to the fingerprint characteristics and the detection principle, the interval between the ridges and the valleys of the fingerprint is generally 8 pixels, and the size of each detection sub-region 200 is set to 8 × 8(K × K) pixels, so as to ensure that there is one ridge or valley in each detection sub-region 200.
The arrangement order of the detection sub-regions will be described below in one embodiment.
Specifically, taking the detection array as 160 × 80 and the number of the detection sub-regions 200 as 16 as an example, as shown in fig. 3, the detection sub-regions 200 are divided into 2 rows, each row of the detection sub-regions 200 includes 8 detection sub-regions 200, wherein the 1 st to 3 rd detection sub-regions 200 have a first interval (e.g., 8), the 3 rd to 6 th detection sub-regions 200 have a second interval (e.g., 16), and the 6 th to 8 th detection sub-regions 200 have a third interval (e.g., 8). In addition, each of the detector sub-regions 200 is a rectangle of K × K (e.g., 8 × 8), and the distance between the detector sub-region 200 and the metal ring 300 is K (e.g., 8).
According to the fingerprint identification device provided by the embodiment of the invention, after the fingerprint identification chip detects that the metal ring is touched and lasts for the first preset time, the number of covered detection subareas is further detected, and if the number is larger than the preset threshold value, the fingerprint identification chip starts fingerprint identification scanning.

And S2, when the metal ring is detected to be touched for a first preset time, the fingerprint identification chip further detects the plurality of detection sub-areas.
Specifically, if the metal ring is touched for a first preset time, which means that there is a finger or a conductor touching the fingerprint identification device, the fingerprint identification chip needs to further determine whether the finger is a valid finger touch, i.e. detect the number of covered detection sub-regions.
And S3, when the number of covered detection subareas is detected to be larger than a preset threshold value, the fingerprint identification chip starts fingerprint identification scanning.
Specifically, if the number of covered detection sub-regions is greater than a preset threshold, it is determined that the finger touch is valid, and then the fingerprint identification chip starts fingerprint identification scanning, performs fingerprint scanning of the entire region, and performs subsequent work such as fingerprint matching.
In addition, if the number of the covered detection subareas is not larger than the preset threshold value, the detection result shows that the finger does not touch effectively, and the fingerprint identification chip continues to detect the metal ring until no finger touches.
In one embodiment of the present invention, the plurality of detector sub-regions are divided into N rows, where N is a positive integer.
In one embodiment of the present invention, each row of detector sub-regions includes M detector sub-regions, where a first interval exists between every two adjacent detector sub-regions in the 1 st to ith detector sub-regions, a second interval exists between every two adjacent detector sub-regions in the ith to jth detector sub-regions, and a third interval exists between every two adjacent detector sub-regions in the jth to mth detector sub-regions, where i is a positive integer smaller than j, and j is a positive integer smaller than M.
