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.

Abstract: Embodiments relate to a gate driving integrated circuit and an operating method thereof operating in a time-division method divided into a display period and a touch period. The gate driving integrated circuit includes a charging circuit, a gate control circuit, and a discharging circuit. The charging circuit charges a memory element. The discharging circuit discharges the memory element. The gate control circuit outputs a gate-on voltage to a gate line based on the charged memory element in during display period. The gate control circuit electrically disconnects the memory element from the gate control circuit during the touch period.

Abstract: An operating method of a touch display driving integrated circuit that is connected with a touch display panel through touch sensing lines and data lines is provided. The method includes applying a common voltage to each touch sensing line, increasing voltages of the touch sensing lines and the data lines by a predetermined level, providing a first touch sensing signal to each touch sensing line, and sensing a touch of a user based on signal variations of the touch sensing lines.
