Abstract: The present invention measures a temperature of a heating element and includes a first insulating layer having an electrical insulating function; a sensor electrode provided on an upper side of the first insulating layer and having a change in intensity of a current according to a change in heat generated by the heating element; and a second insulating layer covering an upper side of the sensor electrode, wherein the sensor electrode is disposed in parallel with the first insulating layer and having a plurality of bent portions from one end of the sensor electrode to the other end of the sensor electrode.

Abstract: 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.
