摘要： An embodiment of the present invention relates to a touch sensing device which drives a touch screen panel comprising: a touch driving electrode extending in a first direction; and a touch sensing electrode extending in a second direction perpendicular to the first direction. The touch sensing device comprises: a first driving unit and a second driving unit, which are driven in at least one among a mutual sensing mode, a first self-sensing mode, and a second self-sensing mode; and a control unit for determining a touch situation on the basis of a mutual sensing signal, which is input according to the mutual sensing mode, to drive the first driving unit and the second driving unit in the first self-sensing mode or the second self-sensing mode.
