The waveform gone out.This is accomplished by performing mutual tolerance Scanning Detction, and Figure 10 passes through the 3rd square wave during touch-control to the 4th square wave phase
Between detect and be illustrated exemplified by touching signals.
Due to from when holding Scanning Detction, the first touch control electrode 1-1, the first touch control electrode 1-2, the are detected from Fig. 9
One touch control electrode 1-5, second touch control electrode 2-2, second touch control electrode 2-3 and second touch control electrode 2-4 have sensed touch-control
Signal.Therefore, only to the first touch control electrode 1-1, the first touch control electrode 1-2, the first touch control electrode 1-5, second touch control electrode 2-
2nd, second touch control electrode 2-3 and second touch control electrode 2-4 performs mutual tolerance Scanning Detction, as shown in figure 11.As shown in Figure 11, it is integrated
Chip only sends mutual tolerance scanning signal to second touch control electrode 2-2, second touch control electrode 2-3 and second touch control electrode 2-4, only connects
Receive the first touch control electrode 1-1, the first touch control electrode 1-2 and the first touch control electrode 1-5 mutual tolerance induced signal.Integrated chip is successively
Mutual tolerance scanning signal is sent to second touch control electrode 2-2, second touch control electrode 2-3 and second touch control electrode 2-4, is touched when to second
When controlling electrode 2-2 transmission mutual tolerance scanning signals, the first touch control electrode 1-1, the first touch control electrode 1-2 or the first touch control electrode are received
1-5 mutual tolerance induced signal, can if integrated chip detects the mutual tolerance induced signal that the first touch control electrode 1-1 is sent
To determine to determine first touching signals by second touch control electrode 2-2 and the first touch control electrode 1-1；Continue to second touch control electrode
2-3 sends mutual tolerance scanning signal, if integrated chip detects the mutual tolerance induced signal that the first touch control electrode 1-5 is sent,
It can determine to determine second touching signals by second touch control electrode 2-3 and the first touch control electrode 1-5；Remaining second touch-control electricity
Pole 2-4 and the first touch control electrode 1-2 determine the 3rd touching signals.Finally, second touch control electrode 2-2 and the first touch-control electricity are passed through
Pole 1-1, second touch control electrode 2-3 and the first touch control electrode 1-5 and second touch control electrode 2-4 and the first touch control electrode 1-2 are determined
Position of the touching signals on contact panel, as shown in figure 11.Both the detection to touching signals had been realized, mutual tolerance has been also reduced and sweeps
The power consumption of detection is retouched, Figure 12 is that second touch control electrode input is side from when being converted to mutual tolerance Scanning Detction from appearance Scanning Detction
The waveform exported in ripple, the first touch control electrode.
In practice, (that is, object is from contact panel is touched to the phase for leaving contact panel during touching signals are present
Between), contact panel has during multiple touch-controls and during display.So, detect touching signals during from the appearance stage, touch-control
2 kinds of situations can be divided into：The first situation：At least last square wave (the 4th square wave) detects touch-control letter during touch-control
Number.It is specific to include again：1st square wave is to detecting touching signals, the 2nd square wave to the 4th square wave phase during the 4th square wave
Between detect touching signals, the 3rd square wave to detecting touching signals, and only the 4th square wave during the 4th square wave
Detect touching signals.Due to during there are multiple touch-controls during touching signals are present and display during, so, first
When square wave in the case of kind during touch-control detects touching signals, touching signals are still present on contact panel, and this can just be protected
When card contact panel from appearance Scanning Detction by being transformed to mutual tolerance Scanning Detction, it can be detected by the square wave during follow-up touch-control
Corresponding relation between touching signals and each first touch control electrode and each second touch control electrode, it is specific as shown in figure 12.In Figure 12,
During mutual tolerance Scanning Detction, integrated chip provides square-wave signal to second touch control electrode successively, and the first touch control electrode is then all in connecing
Receipts state.The first touch control electrode that only there is corresponding relation with there is currently the second touch control electrode of square-wave signal could be detected
To touching signals.As shown in Figure 12, the first touch control electrode 1-1 of second touch control electrode 2-2 correspondences, second touch control electrode 2-3 correspondences
The first touch control electrode 1-2 of first touch control electrode 1-5, second touch control electrode 2-4 correspondence.Contact panel i.e. now has 3 and touched
Signal is controlled, this 3 touching signals and the corresponding relation of the first touch control electrode and second touch control electrode are：Touching signals 1 (2-2,1-
1), touching signals 2 (2-3,1-5) and touching signals 1 (2-4,1-2).
Second of situation：Last square wave does not detect touching signals during touch-control, i.e. the 1st square wave to the 3rd
Touching signals, the 1st square wave are detected during individual square wave to detecting touching signals during the 2nd square wave, and only
1st square wave detects touching signals.But second of situation is just present based on the first situation, without the first situation
Just without second of situation.Due to having been able to detect touching signals and the first touch control electrode and Ge in the first scenario
Corresponding relation between two touch control electrodes, so, second of situation will not be interfered to the detection touching signals of the present embodiment.
It should be noted that above-mentioned Fig. 3-Figure 12 is to include 5 the first touch control electrodes and 5 the second touch-controls with contact panel
The explanation carried out exemplified by electrode, for the first touch control electrode and second touch control electrode comprising other quantity, the present embodiment has
Identical touching signals identification process, is no longer repeated one by one herein.
