Abstract

The present disclosure relates to an electronic device, and more particularly, to an electronic device capable of sensing a stylus pen and an external object such as a finger, which is brought into proximity or contact with the electronic device and reducing the number of channels between a sensor unit and a touch controller. The electronic device according to an embodiment of the present invention includes a sensor unit and a touch controller. Here, the sensor unit includes: a plurality of first patterns, each of which extends in a first direction and has both ends electrically connected to the touch controller; and a plurality of third patterns, each of which extends in a second direction different from the first direction to cross the first pattern and has both ends of which at least one end is electrically connected to the touch controller.
