Abstract
A display device includes a display panel, an input sensor, and a sensor controller. The input sensor includes transmission electrodes, reception electrodes, transmission wires electrically connecting the transmission electrodes to the sensor controller, and reception wires electrically connecting the reception electrodes to the sensor controller. The sensor controller provides transmission signals having different frequencies according to lengths of the transmission wires to the transmission electrodes, respectively. A frequency of each of the transmission signals does not overlap with a frequency component of display noise generated at a position of the display panel corresponding to each of the transmission electrodes, respectively.
