Abstract
A pen detection unit and a display device including a pen detection panel. The pen detection panel includes a plurality of sensor parts, and each of the sensor parts includes a first loop antenna and at least one transistor connected to the first loop antenna. A pen driving circuit detects a position of a pen, based on a sensing signal received through the first loop antenna in a first mode, and transfers the sensing signal to an external electromagnetic induction device in a second mode different from the first mode.
