1. A pen and touch input system comprising: a touch input device comprising a sensor unit and a control unit configured to control the sensor unit; and a stylus pen configured to interact with the touch input device,
wherein the sensor unit comprises:
a plurality of first patterns each extending in a first direction and having first ends electrically connected to the control unit;
a plurality of second patterns each extending in the first direction and disposed adjacent to the first patterns;
a plurality of third patterns each extending in a second direction different from the first direction and having first ends electrically connected to the control unit; and
a plurality of fourth patterns each extending in the second direction and disposed adjacent to the third patterns,
wherein second ends of at least a portion of the plurality of second patterns are electrically connected to each other, and
second ends of at least a portion of the plurality of fourth patterns are electrically connected to each other,
wherein the stylus pen comprises:
a body unit;
a tip exposed to the outside in the body unit;
an inductor unit comprising a ferrite core disposed in the body unit and a coil wound in multiple layers around at least a portion of the ferrite core; and
a capacitor unit disposed in the body unit and electrically connected to the inductor unit to form a resonance circuit,
wherein the control unit applies a touch driving signal to the plurality of first patterns and receives a touch sensing signal from the third patterns, and
the control unit applies a stylus pen driving signal to at least one of the plurality of first to fourth patterns and receives a stylus pen sensing signal from at least one of the plurality of first to fourth patterns.
