However, in step s 40, sensing unit 4 is for performed by each bar first direction wire 1 and second direction wire 2
Alternating expression driving touch control inducing method, mainly from least one first direction wire 1 (or second direction wire 2) launch
One detection signal, and the detection signal is received from least another first direction wire 1 (or second direction wire 2), with sensing
The electric charge of the first direction wire 1 (or second direction wire 2), electric capacity, magnetic flux, electromagnetic induction, voltage, electric current, frequency etc.
Parameter.
The method that sensing unit 4 senses user's finger touch position, can have following several：
Refering to Fig. 3, the first induction mode be sensing unit 4 select first direction wire 1 (such as：X1) transmitting inspection
Survey signal, and from another first direction wire 1 (such as：X2) receive the detection signal, you can sensing first direction wire X2's
Signal changes, and then follows same mode, then from first direction wire X2Transmitting detection signal, from first direction wire X3Connect
Receive detection signal by that analogy, you can sense the signal change of all first direction wires 1.In other words, in a very first time,
Sensing unit 4 can be from first direction wire X1Transmitting detection signal, and from first direction wire X2The detection signal is received, then
In one second time, sensing unit 4 can be from first direction wire X2Transmitting detection signal, and from first direction wire X3Receiving should
Detect signal, so sequentially sense the electric charge of each first direction wire 1, electric capacity, magnetic flux, electromagnetic induction, voltage, electric current,
The parameters such as frequency, until the M-1 times, from first direction wire XM-1Transmitting detection signal, and from first direction wire XMConnect
Receive the detection signal.
Second of induction mode be sensing unit 4 select first direction wire 1 (such as：X1) transmitting detection signal,
And from other several first direction wire 1 (such as：X2~X5) the detection signal is received, so " single bar transmitting, a plurality of reception "
Mode can equally sense all first direction wires 1 signal change.
The third induction mode be sensing unit 4 select several first direction wires 1 (such as：X1~X4) transmitting detection news
Number, and from an other first direction wire 1 (such as：X5) the detection signal is received, so " a plurality of transmitting, single bar connect
The mode of receipts " can also sense the signal change of all first direction wires 1.
4th kind of induction mode be sensing unit 4 select several first direction wires 1 (such as：X1~X2) transmitting detection news
Number, and from several other first direction wires 1 (such as：X3~X4) receive the detection signal, in other words, several first party
Guiding line 1 is divided into several wire groups, and sensing unit 4 can first select one first wire group (such as：X1~X2) transmitting detection news
Number, and from one second wire group (such as：X3~X4) detection signal is received, detection signal is penetrated from second wire mass-sending again afterwards,
And from a privates group (such as：X5~X6) detection signal is received, detection signal is penetrated from privates mass-sending again afterwards, and
From a privates group (such as：X7~X8) receive detection signal；Or first select one first wire group (such as：X1~X2) hair
Penetrate detection signal, and from one second wire group (such as：X3~X4) detection signal is received, afterwards again from privates group's (example
Such as：X5~X6) transmitting detection signal, and from a privates group (such as：X7~X8) receive detection signal；Or first select one
First wire group (such as：X1~X2) transmitting detection signal, and from a privates group (such as：X5~X6) detection signal is received,
Afterwards again from one second wire group (such as：X3~X4) transmitting detection signal, and from a privates group (such as：X7~X8) connect
Detection signal is received, the mode of such " a plurality of transmitting, a plurality of reception " can also sense the signal change of all first direction wires 1
Change.In addition, the above-mentioned at least four wires group, wherein, the first wire group, the second wire group, privates group and should
First direction wire in privates group can be overlapped partly, overlapping or non-overlapping, i.e., direction wire can belong to different simultaneously
Wire group, and same wire group can not sequentially choice direction wire, such as the first wire group can be X1、X3。
5th kind of induction mode and the 4th kind of induction mode are all the mode of " a plurality of transmitting, a plurality of reception ", unlike,
Sensing unit 4 transmitting detection signal the first direction wire 1 can and receive detection signal the first direction wire 1 to
Small part is interlaced with each other, such as：Sensing unit 4 selects first direction wire X1And first direction wire X3Transmitting detection signal, choosing
Select first direction wire X2, first direction wire X4And first direction wire X5Detection signal is received, so can equally sense institute
The signal for having first direction wire 1 changes.In addition, referring to Fig. 6, the first direction wire 1 of transmitting detection signal has one first
Image, and the first direction wire 1 for detecting detection signal can then have one second image, first and second certain direction wire 1,
2 two dimensional image can also be three-dimensional structure substitution, described first image and second image can be strip, rhombus, grid
Shape and variously-shaped or variously-shaped or shape the combination such as square, and the present embodiment is matrix form, and both shapes
It is able to can also be differed with identical.
The density laid due to the first direction wire 1 and second direction wire 2 of the present embodiment is higher, and (i.e. wire pitch is only
Have 30~100 μm), user's finger can cover several first direction wires 1 and second when touching panel (display module 20)
Direction wire 2, therefore, in above-mentioned various induction modes, (or the second direction wire of first direction wire 1 of transmitting detection signal
2) can separately at least one first direction wire 1 with receiving the first direction wire 1 (or second direction wire 2) of detection signal
(or second direction wire 2), such as：Sensing unit 4 selects first direction wire X1Transmitting detection signal, and select first direction
Wire X4Detection signal is received, afterwards again from first direction wire X4Transmitting detection signal, from first direction wire X7Receive detection
Signal by that analogy, is not necessarily required to sense the signal change of all first direction wires 1, to save scanning times and time,
The computing of sensing unit 4 can be similarly set to judge user's finger touching position of display module 20, distance, touching height and touch
Touch a little.In addition, above-mentioned various induction modes are equally applicable to the sensing of second direction wire 2, therefore seldom repeat.
Coordinate refering to Fig. 4,5, by common electrode layer 205 be in suspension joint before sensing unit 4 carries out touch-control scanning, more carefully
Say be in order to avoid sensing unit 4 carry out receive detection signal when by common electrode layer 205 interference, as long as therefore receive examine
Signal is surveyed before by the suspension joint of common electrode layer 205, that is to say, that when display module 20 is during sensing, sensing unit 4 can
To launch detection signal first with above-mentioned one of which induction mode, it is non-that then control circuit 303, which just switches earthed switch 209,
Conducting state receives detection signal, so equally can reach touch-control scanning and optimize again afterwards to be in suspension joint by common electrode layer 205
The effect of control.
