Abstract: A display device comprising a display panel having touch sensors and gate lines, a touch sensor driver configured to supply a touch driving signal to the touch sensors of the display panel during a touch sensor driving period, a gate driver configured to supply a gate pulse synchronized with a data voltage of an input image to the gate lines of the display panel during a display driving period and supply an alternating current (AC) signal having a same phase as the touch driving signal to the gate lines during the touch sensor driving period, and a modulator configured to supply the AC signal having the same phase as the touch driving signal to the gate driver during the touch sensor driving period.
