    Abstract: An exemplary embodiment of the present invention provides a stylus pen including: a body; a conductive tip configured to be exposed from an inside of the body to an outside thereof; and a resonance circuit connected to the conductive tip to resonate an electrical signal transferred from the conductive tip. An inductor unit of the resonance circuit includes a ferrite core and a coil wound in multiple layers over at least a portion of the ferrite core. The ferrite core includes nickel, and the coil can be formed by a litz wire with adjacent winding layers that are wound to be inclined in a zigzag form.

    Abstract: The present invention relates to a multifunctional touch input device capable of detecting a touch position, driving a stylus pen, and detecting a position of the stylus pen.
    The touch input device according to an embodiment of the present invention includes a sensor unit and a control unit for controlling the sensor unit, the sensor unit includes a plurality of patterns. The plurality of patterns include a first pattern extending in a first direction, a second pattern disposed adjacent to the first pattern, a third pattern extending in a second direction different from the first direction, and a fourth pattern disposed adjacent to the third pattern. Here, the plurality of first third patterns have one ends electrically connected to the control unit and the other ends electrically opened. The plurality of first patterns have the other ends that are electrically connected to each other, and the plurality of third patterns have the other ends that are electrically connected to each other.
