Abstract: A display device includes a display panel, an input sensor, and a controller. The controller is operated in a first mode to sense a position at which a first external input is generated, or in a second mode to measure biometric information with respect to a second external input. The controller senses, in the first mode, the position based on a first mode sensing signal to which a variation in capacitance between a transmission electrode and a reception electrode by the first external input is reflected, the controller compensates, in the second mode, for a second mode sensing signal to which a variation in capacitance between the transmission electrode and the reception electrode by the second external input is reflected based on a compensation value to generate a compensation sensing signal, and the controller measures, in the second mode, the biometric information based on the compensation sensing signal.
