Abstract: A display device includes: a touch panel including a touch area including first touch electrodes and second touch electrodes; and a touch panel driver for providing touch driving signals to the first touch electrodes. The touch panel driver provides the touch driving signals to the first touch electrodes in a first touch sensing period of a first mode, operates in a second mode when the first touch is detected, and provides the touch driving signals to the first touch electrodes disposed in a first row area of the touch area in which the first touch is detected in a second touch sensing period of the second mode.

Abstract: A touch sensing device includes a first base layer, a plurality of first sensing electrodes disposed on the first base layer and spaced apart in a first direction, a plurality of second sensing electrodes disposed on a same layer as the first sensing electrodes and arranged in different rows from the first sensing electrodes, a plurality of third sensing electrodes on the second sensing electrodes that are spaced apart along a second direction different from the first direction and that overlap the second sensing electrodes, and a plurality of fourth sensing electrodes on the first sensing electrodes that are spaced apart along the second direction and that overlap the first sensing electrodes. At least two of the second sensing electrodes are directly connected to each other.
