    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.

    Abstract: An active stylus pen is insensitive to external noise and has enhanced sensing performance with respect to an uplink signal input from a touch screen. The active stylus pen includes a housing connected to a ground, a conductive tip protruding outwardly from one side of the housing and brought into contact with a touch screen, a conductor layer surrounding an outer surface of the housing with an insulator interposed therebetween, a pen driving circuit connected to the conductor layer, and a switch connecting the conductor layer and the pen driving circuit. The pen driving circuit is cased by the housing, receives an uplink signal and a touch sensor driving signal from the touch screen, generates a pen driving signal synchronized with the touch sensor driving signal and outputs the generated pen driving signal to the touch screen through the conductive tip.
