Abstract: A touch sensing device determines a contact location of a pen by using a first electrode signal generated from a first electrode of the pen, determines additional information related to the pen by using a second electrode signal generated from a second electrode of the pen, and can determine tilt information of the pen and/or rotation information of the pen by using a profile of the first electrode signal and a profile of the second electrode signal.
