Abstract

An electronic device include a first substrate; a plurality of thin film transistors (TFTs) disposed on the first substrate and a plurality of pixel electrodes connected to the plurality of TFTs, respectively; a second substrate disposed above the first substrate; a plurality of touch electrodes disposed between the first substrate and the second substrate to detect a touch position; a ground layer disposed under the first substrate; and at least one integrated circuit (IC) configured to apply a touch-driving signal to each of the plurality of touch electrodes during a touch-sensitive period, and apply a driven shield signal having an amplitude that is equal to an amplitude of the touch-driving signal to the ground layer during the touch-sensitive period.
