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: A method of compensating for coordinates of an edge portion of a touch sensing system is disclosed. The method includes calculating coordinates of a touch point, suitably converting the coordinates of the touch point based on a resolution of a display panel, deciding whether or not current coordinates of the touch point are present in a bezel area outside an active area of the display panel, in which an image is displayed, and when the current coordinates of the touch point are present in the bezel area, modifying the current coordinates of the touch point into edge coordinates of the active area contacting the bezel area.
