Abstract
A display device includes a folding area and a non-folding area, a display panel including a plurality of pixels, and a digitizer arranged at one side of the display panel and including a plurality of loop coils, where, when a hovering event of an input unit is detected in the folding area, the digitizer increases an alternating current signal applied to at least one loop coil of the plurality of loop coils arranged in the folding area, and calculates a hovering height of the input unit based on a change in a magnetic field between the input unit and loop coils of the plurality of loop coils, the loop coils including a loop coil overlapping the input unit and adjacent loop coils around the input unit.
