An electronic device includes: a display layer; a sensor layer on the display layer, and including: a first electrode, and a second electrode adjacent to the first electrode; and a plurality of crossing electrodes; and a driving circuit electrically connected to the sensor layer to control an operation of the sensor layer. The sensor layer is to operate in a first touch mode to sense a first input signal, and a second touch mode to sense a second input signal of an input device to discharge a magnetic field, and the driving circuit is to sense coordinates of the input device based on a signal profile measured based on a first current having a first current direction formed in the first electrode by the input device, and a second current having a second current direction opposite to the first current direction formed in the second electrode by the input device.
