Abstract
A display device has a display area with a first area in which a fingerprint is recognized and a second area in which a fingerprint is not recognized, and a non-display area. A fingerprint sensing unit is disposed to overlap with the first area. A first pixel set is disposed to overlap with the first area, and a second pixel set is disposed to overlap with the second area, each set including a plurality of pixels. A first voltage signal is provided to the first pixel set as a variable frequency signal, and includes a first period during which the first voltage signal is a first frequency signal, a second period during which the first voltage signal is a second frequency signal having a lower frequency than the first frequency signal, and a third period during which the first voltage signal is the first frequency signal.
