Abstract:
A display device including a display panel having a first area, a second area, and a plurality of pixels to provide an image during a frame period, and a touch panel including a first touch part including first and second touch coils insulated from each other, and a second touch part including first touch electrodes and second touch electrodes insulated each other, in which corresponding second scan signals are applied to the first touch electrodes disposed in the first area when corresponding first scan signals are applied to the first touch coils disposed in the second area during a first period of the frame period, the second touch coils are configured to provide first sensing signals according to a resonant frequency of an input device, and the second touch electrodes are configured to provide second sensing signals according to a variation in a capacitance.
