Abstract
Disclosed is a display device including: a display panel including data lines and gate lines; a touch screen including a plurality of touch screens; a data driving circuit for supplying a data voltage to the data lines; a gate driving circuit for supplying a gate voltage to the gate lines; a touch sensing circuit for applying a driving signal to the touch sensors to sense a change in a voltage or a capacitance value of the touch sensors; and a timing controller for time-dividing a first frame period into a first driving period for sensing the touch sensors and a second driving period for performing display on the display panel, wherein the timing controller performs a control to supply a data voltage to a first area of the first driving period adjacent to a boundary surface between the first driving period and the second driving period.
