Specifically, a shift register may be arranged inside the IC, and the magnitude of the feedback signal of each ITO block 11 is gradually stored, so that the position of the ITO block 11 may be calculated inside the IC according to the stored time sequence, thereby implementing touch sensing.

When the output signal output (n) is turned off and the output terminal is at a low level, the first switching element 1501 is turned off, the second switching element 1502 is turned on, the corresponding ITO block 11 is connected to the reference voltage line 14, and a voltage is supplied to the ITO block 11 from the reference voltage line, so that an electric field is ensured between the ITO block 11 and the Pixel (Pixel) ITO, thereby realizing normal display.
