Abstract
A method of driving a display device includes: sensing a touch signal from a plurality of touch electrodes in a touch panel, sensing a force signal from a force sensor, based on the sensed touch signal, determining whether or not the touch panel is in a submerged state, when the touch panel is determined to be in the submerged state, increasing sensing periods of the touch signal and the force signal, detecting a baseline variation of the force sensor, based on the detected baseline variation, changing a sensing reference value of the force sensor, based on the increasing the sensing periods, sensing the force signal equal to or greater to the changed sensing reference value through the force sensor, and when the force signal equal to or greater to the changed sensing reference value is sensed through the force sensor, decreasing the sensing periods.
