1. An electronic device comprising:
a display layer;
a sensor layer on the display layer, the sensor layer having an active area and a peripheral area adjacent to the active area, wherein the sensor layer is configured to operate in a first mode, in which a first input by an input device is sensed, and a second mode, in which a second input by touch is sensed, wherein the sensor layer comprises a cross electrode that insulately crosses an electrode; and
a controller configured to control the sensor layer,
wherein, in the first mode, the controller is configured to define the active area into a first area defined based on coordinates at which the first input by the input device is sensed and a second area different from the first area and defined based on the coordinates,
wherein the first area is defined as an area overlapping and adjacent to the coordinates and the second area is defined as an area spaced apart from the coordinates and spaced apart from the first area by a predetermined distance with the cross electrode between the first area and the second area within the predetermined distance, and
in the first mode, the controller is configured to provide an uplink signal to the first area and provide a reverse-phase signal having a reverse phase of the uplink signal to the second area, and
wherein the uplink signal has an intensity different from that of the reverse-phase signal.
