Abstract
A touch sensor includes: a sensing area including a first sensing area positioned in a center portion and a second sensing area positioned outwardly therefrom in an edge portion; first sensor electrodes disposed in the first sensing area; and second sensor electrodes disposed in the second sensing area, the second sensor electrodes being configured to be separately activated from the first sensor electrodes. The first sensor electrodes are drivable to detect a touch input generated in the first sensing area in a first mode and the second sensor electrodes are drivable to detect a touch input generated in the second sensing area in a second mode.
