    Abstract: A display device includes a display panel configured to be driven in an initial mode or in a main mode; an input sensing part on the display panel and configured to be driven in a mutual sensing mode or in a self-sensing mode; a fingerprint sensing part below the display panel; and a control module configured to control operations of the display panel, the input sensing part, and the fingerprint sensing part. The display panel is between the fingerprint sensing part and the input sensing part. When the display panel is driven in the initial mode, the control module drives the input sensing part in the self-sensing mode and controls the fingerprint sensing part to detect a fingerprint touched on the input sensing part.
