Abstract
A display device includes a display panel and a touch panel. The touch panel calculates coordinate information of an input position by an electrostatic capacitive method in a first mode and calculates the coordinate information of the input position by an electromagnetic induction method in a second mode. The touch panel includes scan line groups and source line groups, which are operated as touch electrodes or touch coils on the basis of the operating mode thereof. In addition, the touch panel includes touch electrodes and touch coils, which are individually operated on the basis of the operating mode thereof.
