Abstract
An electronic device includes a display panel, an input sensor disposed on the display panel and including first sensing electrodes extending in a first direction and second sensing electrodes extending in a second direction crossing the first direction, and a sensor controller connected to the input sensor. First and second areas are defined in the input sensor based on an input position to which an input by an input device is applied. The input position is located in the first area and not in the second area. The sensor controller applies a first signal to at least one first sensing electrode disposed in the first area and at least one second sensing electrode disposed in the first area and applies a second signal having an opposite phase to a phase of the first signal to the other first and second sensing electrodes disposed in the second area.
