Abstract: An optical device including a first substrate, a light source, a second substrate, an image capturing device, a lens module and a lens holder is provided. The light source outputs a first light beam. The second substrate includes a first surface and a second surface opposite to the first surface and closer to the first substrate. A scattered light beam which is generated by the first light beam entering an object touching the first surface of the second substrate and scattered in the object is a second light beam. The image capturing device receives a third light beam. The third light beam is the second light beam normally incident to the second surface and transmitted to the image capturing device. The lens module focuses the third light beam to be captured by the image capturing device. The lens holder is located between the light source and the image capturing device.

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: The invention provides an optical device. The optical device includes an image capture unit, at least one light emitting device, and a light conductor. The light conductor defines a space above a substrate on which the image capture unit is disposed. The light conductor includes a central portion and a surrounding portion. The central portion is disposed above the space and has a first surface relatively far from the image capture unit and a second surface opposite to the first surface and relatively close to the image capture unit. The surrounding portion is connected to the central portion and surrounding the space. The surrounding portion includes a reflection surface connected to the first surface and tilted at an angle toward the image capture unit with respect to a plane of the first surface. The reflection surface is adapted to perform total reflection.
