There is the first spacing between the adjacent two sensing unit 1222a: this two adjacent sensing unit 1222a of following feature,
First spacing is greater than preset value.This preset value, which can according to need, to be configured, and can be two neighboring in induction structure 1222
(two sensing unit 1222a of the arbitrary neighborhood in induction structure 1222 are equidistant, should for the design spacing of sensing unit 1222a
Spacing is to design spacing) integer (be greater than or equal to 1) times.Namely when receiving touch control operation, induction structure 1222 works
In touch control operation inductive mode.At this point, control circuit 1225 is only to touch area (region of user's finger progress touch control operation)
Interior part sensing unit 1222a (this part sensing unit 1222a constitutes the first sensing unit 1222a group) is acquired, i.e.,
In first sensing unit 1222a group several " sampled points " (i.e. sensing unit 1222a) distribution it is more sparse, sampling precision compared with
It is low.The displacement of finger is usually larger when such control mode design allows for touch-control, it is only necessary to acquire less sensing unit

It answers unit 1222a group to be equally made of several sensing unit 1222a, and exists in the second sensing unit 1222a group with such as
There is the second spacing between the adjacent two sensing unit 1222a of lower feature: this two adjacent sensing unit 1222a, the
The small above-mentioned preset value of two spacing, such as the second spacing can be precisely two neighboring sensing unit 1222a in induction structure 1222
Design spacing (Fig. 7 indicate induction structure 1222 in whole sensing unit 1222a can be collected).Namely it is receiving
When fingerprinting operation, induction structure 1222 works in fingerprinting operation inductive mode.Compared to touch control operation inductive mode, control at this time
Circuit 1225 is to several sensing unit 1222a (these inductions in finger-print region (region of user's finger progress fingerprinting operation)
Unit 1222a constitutes the second sensing unit 1222a group) it is acquired, i.e. several " samplings in the second sensing unit 1222a group
Point " (i.e. sensing unit 1222a) distribution is closeer, and sampling precision is higher.When such control mode design allows for fingerprinting operation
The displacement of finger is usually smaller, needs to acquire more sensing unit 1222a just and fingerprinting operation induction can be achieved.It should be understood that the
In several sensing unit 1222a of two sensing unit 1222a groups, only needing to have a pair of of sensing unit 1222a has the second spacing i.e.
The sampling of degree of precision may be implemented (for touch control operation inductive mode).But in order to guarantee sampling quality and accurate sound
The purpose of fingerprinting operation is answered, two adjacent sensing unit 1222a of any two in the second sensing unit 1222a group can be with
With the second spacing, i.e. each sensing unit 1222a in the second sensing unit 1222a group is equally distributed.Certainly, at it
In his embodiment, the higher mode of such precision can not also be taken, but still through to the first above-mentioned sensing unit
1222a group carries out capacitance acquisition, to respond fingerprinting operation.
In the present embodiment, for touch control operation, the capacitance with the sensing unit 1222a of larger spacing is acquired；For
Fingerprinting operation acquires the capacitance with the sensing unit 1222a of smaller spacing.Pass through such control mode for having differentiation, energy
