In order to preferably illustrate the present invention, illustrated below in conjunction with Fig. 5：
Assuming that integrated gate drive circuitry 13 drives the both sides grid line a total of 1280 of touch-control display panel 16 in Fig. 1 a- Fig. 1 b
Bar, in order to improve report point rate, need to stop 16 times in 1280 grid lines, stop once every 82.Two provided according to Fig. 5
Initial pulse (STV1_L, STV2_L), two termination signals (STV3_L, STV4_L) and the first clock signal to the 4th clock
Signal (CLK1_L, CLK2_L, CLK3_L, CLK4_L), the output of integrated gate drive circuitry 13 stop at 83n (n=1,
2......15) and V-blank (field blanking) place.Such as：The output of integrated gate drive circuitry 13 stops at the 83rd article of grid line
When, interval touch-control period 20*T=200us, the wherein T=10us of the 83rd article of grid line and the 82nd article of grid line, in this period,
83rd article of data wire corresponding to grid line stops refreshing, and touching signals are exported to touch electrode.From this figure it can be seen that integrated grid
Pole drive circuit 13 drive the 83rd article of grid line when, the first clock signal to the 4th clock signal (CLK1_L, CLK2_L, CLK3_L,
CLK4_L it is) 0010.
In a further mode of operation, the first clock signal to the 4th clock signal (CLK1_L, CLK2_L, CLK3_L, CLK4_
