Zusammenfassung:A touch sensor includes a plurality of touch driving electrodes arranged in each of a plurality of touch driving columns in a column direction, and a plurality of touch sensing electrodes arranged in each of a plurality of touch sensing columns in the column direction, the plurality of touch driving columns and the plurality of touch sensing columns being alternately arranged in a row direction. In each of the plurality of touch driving columns, two or more odd-numbered touch driving electrodes among the plurality of touch driving electrodes are substantially simultaneously driven during a first touch group driving period. In each of the plurality of touch driving columns, two or more even-numbered touch driving electrodes among the plurality of touch driving electrodes are substantially simultaneously driven during a second touch group driving period that is different from the first touch group driving period.
