Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Described into ground, it is clear that described embodiment is only part of the embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, those of ordinary skill in the art are obtained every other under the premise of creative work is not made
Embodiment, belong to the scope of protection of the invention.
The embodiment provides a kind of fingerprint identification method, applied to mobile terminal, as shown in figure 1, the fingerprint
Recognition methods includes：
Step 101：If receiving the triggering command of photoelectricity fingerprint recognition, brightness corresponding with current screen brightness is obtained
Dampening information.
Screen in the embodiment of the present invention is photoelectricity fingerprint screen, and photoelectricity fingerprint is the screen light collection based on fingerprint reflection
, above-mentioned triggering command can be specially to detect that finger is pressed into fingerprint induction region.
Above-mentioned brightness decay information may particularly include target environment temperature corresponding with current screen brightness and screen is current
Lasting lighting time.
By obtaining brightness decay information, in order to be adjusted according to the brightness decay information to screen intensity, ensure
Carry out screen intensity during fingerprint collecting.
Step 102：According to the brightness decay information, the target drives voltage of screen is determined.
Whether can first meet the predetermined condition of influence photoelectricity fingerprint recognition in the embodiment of the present invention according to brightness decay information,
And when the brightness decay information meets to influence the predetermined condition of photoelectricity fingerprint recognition, according to brightness decay information, determine screen
Target drives voltage.Such as judge whether environment temperature reaches the predetermined temperature threshold for influenceing photoelectricity fingerprint recognition, or judge screen
Whether the lasting lighting time of curtain reaches the scheduled time threshold value for influenceing photoelectricity fingerprint recognition, if the brightness decay information does not meet
The predetermined condition of photoelectricity fingerprint recognition is influenceed, then directly carries out fingerprint collecting.
Specifically, can according to the brightness decay information and the corresponding relation of driving voltage pre-established, it is determined that with it is described bright
Spend target drives voltage corresponding to dampening information.
Here, according to brightness decay information, determine target drives voltage, so as to according to the target drives voltage to screen
The brightness of curtain is adjusted.
Step 103：According to the target drives voltage, the screen intensity of the mobile terminal is adjusted.
Specifically, according to the target drives voltage, it is determined that destination register corresponding with the target drives voltage is joined
Number；The destination register parameter is sent to drive integrated circult IC；The driving IC is controlled according to the destination register
Parameter, the driving voltage of the screen is adjusted to the target drives voltage.
In the embodiment of the present invention, driving voltage and the corresponding relation of register parameters can be pre-established, as driving voltage is
During 4.5V, corresponding register parameters are 05h, and when driving voltage is 4.4V, corresponding register parameters are 04h, driving voltage
