Abstract
An electronic device may include a display layer that displays an image and a sensor layer disposed on the display layer and sensing an external input. The sensor layer includes a plurality of channels equal to M. M is an integer greater than or equal to 5. A sensor driver drives the sensor layer. In an uplink section, the sensor driver provides an uplink signal to X first channels that are continuously arranged and provides an inverse phase signal having an inverse phase of the uplink signal to Y second channels that are continuously arranged. X and Y are integers greater than or equal to 2. Z off channels that are continuously arranged and are positioned between the first channels and the second channels may be turned off. Z is an integer greater than or equal to 1. M is a sum of X, Y and Z.
