A display device includes a display panel, a sensor controller, and a driving controller. The display panel includes a plurality of pixels, each of which includes a light emitter to emit light to display an image and a plurality of sensors. Each of the sensors includes a light detector to detect user information. The sensor controller is electrically connected with the sensors and is configured to provide a reset control signal to the plurality of sensors. The driving controller determines a first time point initiating when a user is able to attempt to input the user information, determines a second time point when the user information is actually input, and provides the sensor controller with an enable signal to activate the reset control signal after the first time point and deactivate the reset control signal after the second time point.
