Optical fingerprint recognition device and fingerprint sensing device thereof

An optical fingerprint recognition device, comprising:

• a light-emitting diode (LED) array having a plurality of LEDs operated as a plurality of display subpixels, comprising a central LED area and an edge LED area surrounding the central LED area and configured to display a light source pattern in response to a fingerprint sensing request, wherein the light source pattern comprises a central portion displayed by the central LED area and a surrounding portion surrounding the central portion displayed by the edge LED area, and during displaying the light source pattern, a plurality of first LEDs operated as red display subpixels of the central LED area are not illuminating and a plurality of second LEDs operated as red display subpixels of the edge LED area are illuminating;
• and
• a fingerprint sensing device, comprising a sensing pixel array and color filter units disposed above the sensing pixel array, wherein the sensing pixel array comprises a first sensing pixel area and a second sensing pixel area surrounding the first sensing pixel area, the fingerprint sensing device is configured to generate a first fingerprint image according to a plurality of first sensing signals obtained from the 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.
