The solution of the present invention, applied to the simulated touch of target touch point on capacitance touch screen, wherein, the capacitance touch
Screen is mutual capacitance touchscreens, and it has is received by the multiple signal sender electrodes and multiple signals of the arrangement of crisscross array format
Electrode, the crosspoint of each signal sender electrode and signal-receiving electrode is touch point；The present invention is by signal sender electrode
On pumping signal carry out change in gain control after output to signal-receiving electrode, so as to realize simulation in more fine location
Target touch point touch operation, such as the touch operation of pixel rank.
In the prior art, using the electronic equipment of capacitance touch screen such as smart mobile phone, tablet personal computer, its resolution ratio
1920*1080 degree is generally reached, 1920*1080 pixel has also just been corresponded to, if to realize wherein each pixel
If point can be target touch point, 1920 signal sender electrodes and 1080 signals are needed if in the way of background technology
Receiving electrode, cost are higher；The present invention can be achieved with identical using less amount of signal sender electrode and signal-receiving electrode
The simulated touch operation of 1920*1080 pixel.
As shown in figure 1, structural representation local on capacitance touch screen in one embodiment of displaying.In the present embodiment, it is electric
Hold touch-screen and established rectangular coordinate system in the plane, longitudinal direction is x-axis, is laterally y-axis, defines the pair of signal and sends electricity
Extremely x and x+1, the pair of signal-receiving electrode are that y and y+1, x electrode, x+1 electrodes, y electrodes and y+1 electrodes enclose region
Interior target touch point is A.
As shown in Fig. 2 the principle signal of the displaying signal transacting provided by the invention for realizing A points simulated touch operation
Figure.
Preset x electrodes and be corresponding with gain i, x+1 electrode and be corresponding with gain j, y electrode and be corresponding with gain m, y+1 electrode
It is that the pumping signal progress gain amplification for being sent to signal sender electrode uses to be corresponding with gain n, i, j, m, n；This
The mode that invention is controlled using gain adjusts between x and x+1 electrodes or strong and weak between pumping signal is closed on y and y+1 electrodes
System, so that the x position of target touch point A between x+1 and x electrodes can be represented, or represent target touch point A between y and y+1 electrodes
Y location, for example, pumping signal is better than x electrodes after gain process on x+1 electrodes, then A points are electric closer to x+1 in x-axis
Pole.
In other words, it is identical feelings in the intensity of each signal sender electrode or the initial excitation signal of signal-receiving electrode
Under condition, the A points position between x and x+1 electrodes is corresponding gain i and gain j magnitude relationship, between y and y+1 electrodes
A points position is corresponding gain m and gain n magnitude relationship.
Therefore, it can represent that position of the A points in the plane right-angle coordinate is sat by the magnitude relationship of above-mentioned gain
Mark.
To realize target touch point simulated operation, it is necessary to by the signal of two neighboring signal sender electrode after gain process
Two signal-receiving electrodes are sent respectively to, using above-mentioned gain as gain component, target used in the gain process increases
Beneficial size is with the signal sender electrode as pumping signal sender and as corresponding to the signal-receiving electrode of its recipient
Gain component superposition.
Specifically, when simulating the operation of A touches, the pumping signal of x electrodes is defeated through gain m amplifications again through gain i amplifications
Go out to y electrodes, the pumping signal of x electrodes is amplified through gain i is output to y+1, the pumping signal of x+1 electrodes through gain n amplifications again

The pumping signal of electrode is merged after gain j amplifications and (is added in the present embodiment), then is output to respectively through gain m amplifications
Y electrodes, y+1 electrodes are output to through gain n amplifications, realize the simulated touch operation of A points；Certainly, sent if A points fall in a signal
When on electrode and between two signal-receiving electrodes, such as fall on x electrodes, and between y and y+1 electrodes, then x is electric
The pumping signal of pole is output to y electrodes after gain i and gain m amplifications, and the pumping signal of x electrodes is amplified through gain i and gain n
After be output to y+1 electrodes, to simulate A touches；Or A points fall between two signal sender electrodes, and fall and connect in a signal
When receiving on electrode, such as fall between x and x+1 electrodes, and on y electrodes, then the pumping signal of x electrodes is through gain i and increasing
Y electrodes are output to after beneficial m amplifications, the pumping signal of x+1 electrodes is output to y electrodes after gain j and gain m amplifications, to simulate A
Touch.
Fig. 1 to Fig. 3 illustrates the embodiment of single-touch, in a practical situation, can realize that multiple spot touches by that analogy
Touch.
In a practical situation, the principle due to capacitance touch screen in itself makes so, two touch point meetings between adjacent electrode
Identified is same, such as the A points between x and x+1 electrodes, the B points between x+1 and x+2 electrodes, can be identified as same
Individual point；Therefore, each target touch point in multiple point touching be will not be adjacent with same electrode touch point, such as x and x
A points between+1 electrode, the C points between x+2 and x+3 electrodes.

Between, F points are located at xcAnd xc+1Between electrode, then simulate multiple point touching operation when xaAnd xa+1Electrode, xbAnd xb+1Electrode, xcWith
xc+1Pumping signal on electrode carry out being sent to after the gain process described by embodiment before as described in y electrodes and y+1 electricity
Pole, such as xaAnd xa+1It is o, p that electrode pair, which answers gain, and it is m, n that y and y+1 electrode pairs, which answer gain, then such as the exhibition of previous embodiment institute
Show and the processing of gain superposition is carried out to pumping signal as principle and is sent to y and y+1 electrodes.
