Classification: CPC G  H | IPC G  H

Claim 17:
18. A driving method of an electronic device, comprising:
receiving a plurality of sensing signals from a sensor layer comprising a plurality of cross electrodes extending along a first direction, and a plurality of electrodes extending along a second direction crossing the first direction;
sampling each of the plurality of sensing signals at a selection sampling frequency higher than a reference sampling frequency to obtain a plurality of sampling values;
comparing sampling values adjacent to each other from among the plurality of sampling values to calculate a plurality of pieces of change data;
comparing a comparison target value derived from the plurality of pieces of change data with a threshold, and dividing the plurality of sensing signals into a valid signal and a noise signal;
calculating intermediate coordinates based on the valid signal; and
correcting the intermediate coordinates based on the noise signal to calculate input coordinates.
