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 includes a sensor unit and a control unit, the sensor unit including 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.
