Abstract:
An operating method of a touch driving integrated circuit (TDI) sensing a user touch on a touch panel includes: transmitting a first touch signal through a transmission line connected with the touch panel; receiving a first sensing signal through a reception line connected to the touch panel; receiving a first display noise through a detection line connected to the touch panel; and offsetting a noise included in the first sensing signal by using the first display noise.
