In the electrode 12 entirely embodiment of sensor electrode 122, detecting step includes following sub-step:
Drive signal is applied to the sensor electrode 122 of n*k+c row or column, wherein, for natural number and inclusion zero, n is certainly to k
So number and more than or equal to 2, c be natural number and include zero, c be less than n, n*k+c≤N, and k different from c when be zero, N be described biography
Total line number of sensor electrode or total columns;
Induced signal on sensor electrode 122 in addition to the sensor electrode 122 of n*k+c row or column for the detection;
Drive signal is applied to a line in addition to the sensor electrode 122 of n*k+c row or column or sensor electrode 122;
And
The induced signal of the sensor electrode 122 of detection n*k+c row or column.
In some embodiments, above-mentioned sub-step can be realized by detection module 12, that is to say, detection module 12 can
For applying drive signal to the sensor electrode 122 of n*k+c row or column, wherein, k is natural number and includes zero, n for nature
Count and for natural number and include zero, c less than n, the biography detecting in addition to the sensor electrode 122 of n*k+c row or column more than or equal to 2, c
The induced signal of sensor electrode 122, a line sensor electrode 122 in addition to the sensor electrode 122 of n*k+c row or column is applied
The induced signal of the sensor electrode 122 of drive signal and detection n*k+c row or column.

Device electrode 122 applies drive signal to obtain the induced signal of all the sensors electrode 122.So, the applying of drive signal and
The detection of induced signal is more regular, can simplify the control of testing circuit, in addition, the process to the induced signal detecting
Also it is easy to become.
It is appreciated that n, k and c are constant, and non-variables is it is possible to arrange according to demand.
It is appreciated that n than larger when, drive signal will be applied to the sensor electrode 122 being spaced distant row or column,
So, it is understood that there may be from sensor electrode 122 sensor electrode 122 farther out applying drive signal, lead to induced signal relatively
Weak, even if it should also be recognized, however, that such embodiment, ratio does not apply during drive signal by force, therefore induced signal yet yet
Can realize detecting.For example, work as n=10, c=1, drive signal is applied to the sensor electrode 122 of 10k+1 row or column, then
The sensor electrode 122 of 5k+1 row or column is from sensor electrode 5 row or column applying drive signal, distant, accordingly, it is possible to lead
Cause the sensing letter signal that the sensor electrode 122 of 5k+1 row or column produces weaker.But, such induced signal still can be used
In detection sensor electrode 122.And in such embodiment, can be to the sensor electrode 122 of fewer row or column
Apply drive signal and can achieve detection, therefore, it can reduce the power consumption of detection.
Certainly, in other implementations, in order to more efficient, more accurately detection sensor electrode 122 it is also possible to close
Reason setting n, thus avoid induced signal weaker.It is appreciated that n is less, the induced signal that same drive signal can produce
Stronger.Refer to Fig. 5, n=2, c=1, in other words the sub-step of detecting step is:

Refer to Fig. 6, another example of embodiment above can be that sensor electrode 122 in column is applied to drive
Signal, and n=2, c=1, in other words the sub-step of detecting step be:
The sensor electrode 122 that odd number (2k+1) is arranged applies drive signal;
The induced signal of the sensor electrode 122 of detection even column (in addition to odd column);
The sensor electrode 122 of dual sequence (in addition to odd column) applies drive signal;And
The induced signal of the sensor electrode 122 of detection odd column (2k+1).
The benefit of both the above example is, due to being applied in the sensor electrode 122 of drive signal and examined sensing
Device electrode 122 is interlacing, and the coupling effect of fringe field is strong, and the voltage signal therefore detecting is strong, beneficial to judgement below.
Refer to Fig. 6, in other example, can be that drive signal is applied to rows of sensor electrode 122, and n
=3, c=1, in other words the sub-step of detecting step be:
Drive signal is applied to the sensor electrode 122 of 3k+1 row;
The induced signal of sensor electrode 122 in addition to 3k+1 row for the detection;
A line (such as 3k+2 row) sensor electrode 122 to the sensor electrode 122 in addition to 3k+1 row applies to drive letter
Number;And
The induced signal of the sensor electrode 122 of detection 3k+1 row.
It is appreciated that in such example, being applied in the row of the sensor electrode 122 of drive signal by reasonable selection
Number, it is possible to reduce be applied in sensor electrode 122 sum of detection, such that it is able to reduce energy consumption.
Certainly, above example is only to embarking on journey or embark on journey in column or sensor electrode 122 in column applies drive signal
Or drive signal change signal, to obtain the explanation of the induced signal of all the sensors electrode 122, should not limit this practicality new
