Referring to Fig. 5, Fig. 5 is the flow chart of the driving method of the electronic equipment.The driving method includes step
S11, step S12, step S13.
Step S11, the output of the detecting element 132 detection signal.
Specifically, when user operates the fingerprint identification device 130 and contacts the detecting element 132, the detection
Element 132 exports first detection signal, in one embodiment, since the detecting element 132 touches user's finger
Ground connection, therefore the first detection signal is low level signal.Do not have when there is no user to operate the fingerprint identification device 130 yet
There is user to contact the detecting element 132, the output of detecting element 132 second detects signal, in one embodiment, by
Being not exposed to user in the detecting element 132, therefore the detecting element 132 is not grounded, the second detection signal
It can be high level signal.When operating the fingerprint identification device 130 without user in the given time and contact the inspection
Element 132 is surveyed, the detecting element 132 exports the second detection signal, such as high level signal always within the predetermined time.
Step S12, the processor 140 judge whether there is user according to the detection signal and operate the fingerprint recognition
Device 130.
In step S12, when the detection signal is first detection signal (such as low level signal), the processor
140 think have user to operate the fingerprint identification device 130 according to first detection signal judgement；When the detection signal
Duration for the second detection signal (such as high level signal) and the second detection signal is more than predetermined time (such as three seconds)
When, the judgement of processor 140 thinks that no user operates the fingerprint identification device 130.
Step S13, the processor 140 according to judging result control the fingerprint sensor 131 enter working condition or
Dormant state, wherein the fingerprint sensor 131 is detected after entering working condition and is applied on the fingerprint sensor 131
Touch action or fingerprint characteristic.

Row unlocked by fingerprint, payment and account such as log at first control function)；Pass through fingerprint when the electronic equipment 100 is not in
When verifying the state of identity, the processor 140 receives the output signal of the fingerprint sensor 131, and the fingerprint is passed
The output signal of sensor 131 is considered as common touch signal to control and execute relevant control (such as according to the common touch signal
Execute and return to Previous Menu, into next stage menu and return to second control function such as homepage)
Specifically, if the output signal is consistent with preset fingerprint signal, the control of processor 150 executes described logical
The control function (such as execution unlocked by fingerprint, payment and account log in the first control function) for crossing fingerprint authentication, if described
Output signal and preset fingerprint signal are inconsistent, then it is aobvious by the touch-control to control the electronic equipment 100 for the processor 150
Show that mould group 112 exports default prompt information in viewing area 103.The default prompt information can be for " fingerprint matching is unsuccessful, asks
Fingerprint is inputted again " information of meaning.
Further, described when the electronic equipment 100 is in the state by fingerprint authentication identity in step S13
Processor 140 controls the fingerprint identification device 130 with the first precision acquisition finger print information and output signal；When the electronics is set
Standby 100 when being not in the state by fingerprint authentication identity, and the processor 140 controls the fingerprint sensing device 130 with low
In the second precision acquisition finger print information output signal of first precision.
Referring to Fig. 6, Fig. 6 is the structural schematic diagram of the fingerprint sensor 131 of the fingerprint identification device 130.The finger
Line sensor 131 includes multiple pixels 1311.When the fingerprint identification device 130 is with the first precision acquisition finger print information, institute
It states multiple pixels 1311 to acquire fingerprint and export fingerprint signal, the processor 140 is exported according to the multiple pixel 1311
Fingerprint signal obtain the first finger print information, and by first finger print information and preset fingerprint information comparison with according to comparing knot
Fruit controls whether to pass through fingerprint authentication.
In one embodiment, the multiple when the fingerprint identification device 130 is with the second precision acquisition finger print information
Pixel 1311 is divided into multiple pixel groups 1312, and each pixel group 1312 includes several pixels 1311 being disposed adjacent, each picture
At least one pixel 1311 in element group 1312 acquires fingerprint and exports fingerprint signal (such as output of only one pixel 1311 fingerprint letter
Number, other pixel suspend mode are without exporting fingerprint signal), the processor 140 exports more according to the multiple pixel group 1312
A fingerprint signal obtains the second finger print information, and second finger print information is considered as common touching signals and is controlled described in execution
The corresponding control function of common touching signals.
In another embodiment, described more when the fingerprint identification device 130 is with the second precision acquisition finger print information
A pixel 1311 is divided into multiple pixel groups 1312, all in each pixel group 1312 under the control of the processor 140
Pixel 1311 is applied driving signal simultaneously and exports the fingerprint signal (output of all pixels 1311 of the pixel group 1312 simultaneously
Identical fingerprint signal), the processor 140 obtains the second fingerprint according to the fingerprint signal that the multiple pixel group 1312 exports
Second finger print information is simultaneously considered as common touching signals and controlled and execute the corresponding control of the common touching signals by information
Function.
Further, in one embodiment, after the fingerprint sensor 131 enters working condition, the processor
140 also control to the detecting element 132 application pumping signal or ground signalling to cooperate the identification of fingerprint sensor 131 touching
Touch movement or fingerprint characteristic.It is appreciated that the pumping signal can be radiofrequency signal.
