Abstract: A display device includes a display panel, a plurality of first sensing electrodes disposed on the display panel, and a plurality of second sensing electrodes disposed on the first sensing electrodes and isolated from the first sensing electrodes. A wire width of each first sensing electrode of a second group is smaller than a wire width of each first sensing electrode of a first group, and a wire width of each second sensing electrode of a fourth group is smaller than a wire width of each second sensing electrode of a third group.

Abstract: An electronic device includes an input sensor that senses an input from an outside source to obtain a sensing coordinate. The input sensor has a plurality of sensing units defined therein. A memory stores a first modeling data obtained from first and second sensing units and a second modeling data obtained from first and third sensing units. A controller corrects the sensing coordinate to obtain a calculated coordinate. The controller comprises a first reference point moving unit that converts the sensing coordinate into a first middle coordinate based on a coordinate system having a plurality of coordinate units. A coordinate correction unit obtains a second middle coordinate by correcting the first middle coordinate based on the first and second modeling data. A second reference point moving unit obtains the calculated coordinate based on the second middle coordinate.
