The fingerprint identification device 10 of embodiment, comprising: fingerprint recognition chip 100, multiple detection subregions 200 and becket 300.
Wherein, multiple detection subregions 200 are arranged on fingerprint recognition chip 100, and becket 300 is around fingerprint recognition
Chip 100.Fingerprint recognition chip 100 is used for after detecting that becket 300 is touched and continues the first preset time, detection
The quantity of capped detection subregion 200, if quantity is greater than preset threshold, fingerprint recognition chip 100, which starts fingerprint, to be known
It does not scan.
Specifically, becket 300 connects the transmitting pin inside fingerprint recognition chip 100, both is used to do the transmitting of signal
Pole, and be used to do CSD detection (i.e. capacitance detecting), multiple detection subregions are people on the surface array of fingerprint identification chip 100
For the region of setting, the foundation for judging finger area coverage can be used as.
More specifically, when fingerprint recognition chip 100 detects that the becket 300 is touched and continues the first preset time
Later, Sub_area (indicating detection subregion) detection will be triggered, Sub_area detection is triggered, and judges finger pressing
Whether area reaches acquisition threshold value, that is, whether fingerprint recognition chip 100 detects the capped quantity for detecting subregion 200
Greater than preset threshold, if so, the fingerprint recognition scanning function of fingerprint recognition chip 100, i.e. fingerprint recognition chip will be waken up
100 carry out the finger scan of whole region, then carry out the follow-up works such as fingerprint matching.In addition, if capped detection sub-district
The quantity in domain 200 is not more than preset threshold, illustrates not to be effective finger touch, then, fingerprint recognition chip 100 continues to gold
Belong to ring 300 to be detected, up to no finger touches.
As shown in Fig. 2, the application of fingerprint identification device 10 of the embodiment of the present invention is on mobile terminals, wherein fingerprint recognition
