Abstract: Disclosed is a touch sensing device for implementing a high resolution, which decreases a touch sensing period of an active pen in one frame to increase a display period. The touch sensing device includes a touch driver transmitting an uplink signal to an active pen through a touch electrode provided in a display panel during a first touch sensing period included in one frame period, a touch sensing unit sensing a downlink signal transmitted from the active pen on the basis of a capacitance occurring between the active pen and the touch electrode to generate first sensing data during a plurality of second touch sensing periods included in the one frame period, and a touch controller calculating pen data and pen touch coordinates of the active pen on the basis of the first sensing data generated during the second touch sensing period.
