Abstract
A touch sensor includes a plurality of driving electrodes, a plurality of sensing electrodes that intersect the plurality of driving electrodes, a driver configured to substantially simultaneously supply driving signals to at least some of the plurality of driving electrodes, a sensing unit configured to detect sensing signals from the plurality of sensing electrodes, and a touch controller configured to control the driver so that the number of driving electrodes to which the driving signals are supplied in a first driving period is different from the number of driving electrodes to which the driving signals are supplied in a second driving period.
