Abstract: A display device includes a touch sensor, a fingerprint sensor, and a sensor driver. The touch sensor generates a touch sensing signal in response to touch of an object on a display panel. The fingerprint sensor detects the object in a first mode to generate a first sensing signal and detects the object in a second mode to generate a second sensing signal. The sensor driver calculates a touch position and a moisture level of the object based on the touch sensing signal, generates fingerprint information based on the first sensing signal, and corrects the moisture level based on the second sensing signal.
