Abstract: A fingerprint identification device and a fingerprint identification method are provided. The fingerprint identification device includes a self-emitting display panel, a fingerprint sensor and a processor. The self-emitting display panel displays at least one light pattern in a sensing region. The fingerprint sensor senses a finger object located above the sensing region of the self-emitting display panel to generate a first fingerprint image and a second fingerprint image corresponding to the at least one light pattern. The processor is coupled to the fingerprint sensor. The processor determines whether the first fingerprint image and the second fingerprint image have opposite tones to identify the finger object is a real finger or a fake finger.

Abstract: An electronic device with fingerprint sensing function including a display panel, a fingerprint sensing module and a supporting frame are provided. The fingerprint sensing module includes a light source and an image sensor. The light source is configured to emit an illuminating light. The supporting frame is disposed between the display panel and the fingerprint sensing module for supporting the display panel. The supporting frame includes a first plane facing the display panel, a second plane facing the fingerprint sensing module, and an oblique through hole between the first plane and the second plane. The illuminating light is guided toward a sensing object above the display panel through the oblique through hole.
