Abstract
Provided is an electronic device including a sensor layer, and a sensor driver configured to drive the sensor layer and selectively operate in a first mode for sensing touch inputs or a second mode for sensing pen inputs. The sensor layer includes a plurality of first electrode groups arranged along a first direction, and a plurality of second electrode groups arranged along a second direction crossing the first direction and crossing the plurality of first electrode groups. Each of the plurality of second electrode groups include a first cross electrode and a second cross electrode, and in the second mode, the sensor driver is configured to receive a first signal from the first cross electrode and a second signal from the second cross electrode.
