Abstract: A display device includes: a display panel configured to display an image; an input sensor on the display panel and configured to operate in a first sensing mode or a second sensing mode different from the first sensing mode; and a sensor controller configured to drive the input sensor, wherein the sensor controller is configured to drive the input sensor under a first driving condition different from a driving condition of the first sensing mode in response to the second sensing mode being entered, and the sensor controller is configured to change the first driving condition to a second driving condition different from the first driving condition according to a specific event which occurs after entering the second sensing mode.
