Abstract
A touch sensing device includes a panel including pixels disposed in a matrix form defined by data lines and gate lines, the pixels including thin film transistors (TFTs). The touch sensing device includes at least one touch sensor having a mutual capacitance and a sensor driving circuit configured to receive an electric charge from the mutual capacitance. The touch sensing device further includes a display driving circuit configured to supply a first parasitic capacitance suppressing signal to the data lines and a second parasitic capacitance suppressing signal to the gate lines during a touch sensor driving period.
