Zusammenfassung:An electronic device includes: a display layer to display an image; a sensor layer on the display layer; and a sensor driver electrically connected with the sensor layer, and to be selectively driven in a first mode for detecting a passive input, or a second mode for detecting an active input. In the second mode, the sensor driver is 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.
