Abstract
A display device includes: a pixel including a light emitting element; a sensor including a sensing element and a sensor driving circuit; and a sensor driver to output a sensor scan signal to the sensor driving circuit. The sensor driver includes: a switching circuit connected between a first input terminal for receiving a first clock signal of a first operating frequency and a first clock node, and to output a first filtering clock signal of a second operating frequency to the first clock node in response to a first enable signal; and a driving circuit to output the sensor scan signal in response to the first filtering clock signal of the first clock node.
