Abstract
A display device includes a display panel that displays an image, an input sensor that senses an external input, and a sensing controller that controls the driving of the input sensor. The input sensor includes a plurality of scanning electrodes and a plurality of sensing electrodes. The sensing controller simultaneously transmits input scanning signals to at least two scanning electrodes of the plurality of scanning electrodes during a group scanning period. The group scanning period includes a plurality of scanning periods. The sensing controller transmits a compensating signal having a phase different from a phase of at least one of the input scanning signals to at least one sensing electrode of the plurality of sensing electrodes during at least one scanning period of the plurality of scanning periods.
