description Disclosed is a display device with integrated touch screen that may include a panel including a plurality of electrodes; a touch IC that applies a touch scan signal to the plurality of electrodes during a predetermined period of an n−1th frame ('n' is an integer above 2), and checking whether or not there is a touch input in the panel through the use of information received from the plurality of electrodes; and a display driver IC that applies a common voltage to the plurality of electrodes during a first period of an nth frame if there is the touch input in the panel, and applying the common voltage to the plurality of electrodes during a second period of the nth frame if there is no touch input in the panel, wherein the second period is longer than the first period.
