Zusammenfassung:Disclosed are a device and a method of sensing a touch using an oscillation circuit. Touch sensor lines that detect a position by using a resistor and a capacitor of an RC oscillation circuit face each other to make pairs in a panel, and an oscillation frequency generated according to capacitance of the panel which is changed by a touch is measured through the adjacent touch sensor lines and two or more characteristics of the measured oscillation frequency are calculated to determine the touched position.
