1. A display device, comprising:
- a display panel comprising a first display substrate and a second display substrate facing the first display substrate;
scan line groups, each scan line group comprising a first scan line sub-group, a second scan line sub-group connected to the first scan line sub-group, and a third scan line sub-group disposed between the first scan line sub-group and the second scan line sub-group;
source line groups, each source line group comprising a first source line sub-group, a second source line sub-group connected to the first source line sub-group, and a third source line sub-group disposed between the first source line sub-group and the second source line sub-group;
a first driver configured to provide first scan signals to the scan line groups in a first mode and to provide second scan signals to the scan line groups in a second mode, a magnetic field being induced by a current path formed by the first scan line sub-group and the second scan line sub-group;
a second driver configured to provide first sensing signals corresponding to a variation in a capacitance from the source line groups in the first mode, and to provide second sensing signals according to a resonant frequency associated with an input device, the second sensing signals being provided from the source line groups in the second mode; and
a touch sensor configured to receive the first sensing signals and the second sensing signals and to determine coordinate information of an input position based on the first sensing signals and the second sensing signals.

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.
