20100277433TOUCH PANEL DEVICE AND METHOD OF DETECTING CONTACT POSITION THEREOF - Provided are a touch pad device and a method of detecting a contact position thereof. The touch panel device includes: a touch panel having a surface on which at least one pair of touch patterns formed of a conductive material are formed; and a touch sensor for generating a contact signal corresponding to a contact position of a contact object using impedances of a pair of touch patterns when the pair of touch patterns are contacted by the contact object. The touch panel device includes a plurality of pairs of touch patterns formed of a conductive material. A first axis position of a contact object is determined depending on whether or not the touch patterns are contacted by the contact object, and a second axis position of the contact object is determined by detecting variations in capacitance of the touch patterns or delay times by which a reference signal applied to the touch patterns is delayed. Thus, a contact position of the contact object can be detected using the first and second axis positions. Since the touch panel uses a one-layer ITO film, manufacturing the touch panel device with improved transparency can be easy and economical.11-04-2010
