Abstract: A method of measuring skin moisture includes: measuring, in response to a touch on a touch panel, a first capacitance for a touch area in association with driving first and second electrodes of the touch panel in a mutual sensing mode; measuring, in response to the touch, a second capacitance for the touch area in association with driving one electrode of the first and second electrodes in a self-sensing mode; comparing the first capacitance with a first reference capacitance; determining, in response to the first capacitance being greater than the first reference capacitance, a skin moisture level using the first capacitance and the second capacitance; comparing, in response to the first capacitance being less than the first reference capacitance, the second capacitance with a second reference capacitance; and compensating, in response to the second capacitance being greater than the second reference capacitance, the first capacitance using the second capacitance.
