An optical fingerprint recognition device includes a light-emitting diode (LED) array and a fingerprint sensing device. The LED array includes a central LED area and an edge LED area, and configured to display a light source pattern in response to a fingerprint sensing request. The light source pattern includes a central portion and a surrounding portion. During displaying the light source pattern, a plurality of red display subpixels of the central LED area are not illuminating and a plurality of red display subpixels of the edge LED area are illuminating. The fingerprint sensing device generates a first fingerprint image according to a plurality of first sensing signals obtained from a plurality of first sensing pixel area, and the first fingerprint image is adapted to be used for examining whether a finger which triggers the fingerprint sensing request is real or fake.
