Abstract: A touch device according to an embodiment includes: a plurality of touch electrodes; and a touch controller for measuring a voltage varied based on a short circuit resistance of the touch electrodes and detecting short-circuit states of the touch electrodes.

Abstract: A stylus pen according to an exemplary embodiment includes: a main body; a holder that is connected to the main body and of which an opening is formed at an end thereof; a stylus tip that is formed by being partially or wholly derived in the opening of the holder, and of which at least a part has a shape of a sphere or a shape of which some area contacting a sense surface has a constant curvature; and a conductive member that is electrically connected to the stylus tip and extends to the holder and the interior of the main body. According to the exemplary embodiments of the present invention, a program caused due to tilting of the stylus pen can be solved and touch sensitivity of the stylus tip can be enhanced.
