Step S5 resolves the touch-control coordinate;
After definite this touching signals was useful signal, this touch-control driver 103 was resolved the coordinate of position of touch according to this touching signals.In the cartesian coordinate system shown in Fig. 2, this sweep trace G1～Gn is parallel to the X-direction of coordinate system, its corresponding Y-axis coordinate is respectively Y1～Yn, and these many touch-control line S1～Sm are parallel to the Y direction of coordinate system, and its corresponding X-axis coordinate is respectively X1～Xm.The touching signals that reads as this touch-control driver 103 comes from this touch-control line Sk, determines that then the X-axis coordinate of position of touch is Xk.Owing to have only when this transistor seconds 170 is scanned, this touch-control driver 103 could read touching signals from this touch-control line Sk, then will receive the time signal of touching signals and the scanning sequence signal contrast of this scanner driver 102, can discern the current sweep trace Gi that is scanned, the Y-axis coordinate Yi of this sweep trace Gi correspondence is the Y-axis coordinate of position of touch, thereby finally the coordinate of definite this position of touch is (Xk, Yi).
Step S6, output touch-control coordinate.
At last, (Xk, Yi), (Xk Yi) operates this touch control liquid crystal display device 100 these touch-control driver 103 output touch-control coordinates accordingly according to the touch-control coordinate.
Compared to prior art, these touch control liquid crystal display device 100 inside are provided with this contact electrode 116, this transistor seconds 170 and this touch-control line S1～Sm, move by touch-control, this contact electrode 116 is surveyed the voltage signal of this public electrode 123 and by this transistor seconds 170 and touch-control line S1～Sm this voltage signal is transferred to this touch-control driver 103, voltage signal by analyzing this touch-control line S1～Sm also contrasts the time of this voltage signal and the scanning sequence signal of this scanner driver 102, can determine the coordinate of position of touch.This touch control liquid crystal display device 100 self can be realized touch controllable function, and does not need extra touch-screen, and its thin thickness, in light weight helps the lightening development of touch control liquid crystal display device.Simultaneously, because this touch control liquid crystal display device 100 does not use touch-screen and pastes band and wait element, light needn't pass touch-screen and paste band and wait element, can reduce bad phenomenon such as light absorption, refraction, reflection and interference, effectively improve the transmittance and the display effect of this touch control liquid crystal display device 100.
In the driving method of this touch control liquid crystal display device 100, utilize the public voltage signal of sweep signal and these contact electrode 116 sensings to resolve the coordinate of position of touch, liquid crystal display and touch-control location are blended in the unified driving method, have driving simply, the characteristics of accurate positioning.
