1. An electronic device, comprising:
a display layer configured to display an image;
a sensor layer on the display layer; and
a sensor driver electrically connected with the sensor layer, and configured to be selectively driven in a first mode for detecting a passive input, or a second mode for detecting an active input,
wherein, in the second mode, the sensor driver is configured to:
receive a plurality of sensing signals from the sensor layer;
divide the plurality of sensing signals into a valid signal and a noise signal;
calculate intermediate coordinates based on the valid signal; and
correct the intermediate coordinates based on the noise signal to calculate input coordinates.
