Abstract: A display device includes a display panel including a plurality of pixels arranged in an image display area, a touch sensing unit disposed on a front surface of the display panel that senses a touch of a user's body part and a touch of an electronic pen, a display driving circuit that drives the pixels of the image display area, and a touch sensing circuit that generates touch coordinate data by detecting touch positions of the user's body part and the electronic pen. The touch sensing circuit senses the touch of the user's body part and allows the electronic pen to be charged during a touch electrode driving period by supplying touch driving signals generated by mixing driving signals of different frequency bands to touch electrodes during the touch electrode driving period.
