15. An electronic device comprising:
a display layer that displays an image;
a sensor layer disposed on the display layer and sensing an external input, the sensor layer including a plurality of channels; and
a sensor driver that drives the sensor layer,
wherein, in each of uplink sections prior to determining that an input device is present, the sensor driver provides an uplink signal to a group of plurality of first channels that are continuously arranged and directly border each other, and provides an inverse phase signal having an inverse phase of the uplink signal to a group of plurality of second channels that are continuously arranged and directly border each other, the plurality of second channels are different from the plurality of first channels, and the sensor driver does not provide the uplink signal and the inverse phase signal to off channels that are sequentially arranged among the plurality of channels and directly border each other and are positioned to directly border the group of the plurality of first channels and directly border the group of the plurality of second channels,
wherein the uplink sections include a first uplink section and a second uplink section subsequent to the first uplink section, and
wherein in the first uplink section, the plurality of channels are sequentially defined as the plurality of first channels, the off channels, and the plurality of second channels, and in the second uplink section, the plurality of channels are sequentially defined as the plurality of second channels, the off channels, and the plurality of first channels.
