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.

Abstract: A display device includes a display panel and an input sensing panel. The input sensing panel includes pluralities of first and second sensing electrodes and electrostatic induction patterns, each of which is connected to a sensing electrode from one of the pluralities of sensing electrodes and overlaps another sensing electrode from the other one of the pluralities of sensing electrodes. The input sensing panel includes a first area where deviations of mutual capacitances between the first and second sensing electrodes are small and a second area where the deviations are large. The electrostatic induction patterns include first electrostatic induction patterns disposed in the first area and second electrostatic induction patterns disposed in the second area, the second electrostatic induction patterns having a different area from the first electrostatic induction patterns, or the number of second electrostatic induction patterns being different from the number of first electrostatic induction patterns.
