摘要： An embodiment of the invention provides an optical device including a first substrate, a light source, a second substrate, an image capturing device, a lens module and a lens holder. 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.

摘要： An optical device including a first substrate, a light source, a second substrate, an image capturing device, a microstructure layer, and an infrared pass layer is provided. The light source is disposed on the first substrate. The second substrate is disposed above the first substrate. The second substrate includes a first surface and a second surface opposite to the first surface. The image capturing device is disposed on the first substrate to receive a light beam, which is originated from scattered light beams scattered by an object touching the first surface of the second substrate. The microstructure layer is disposed on the first surface of the second substrate. The microstructure layer is adapted to increase a light beam, which is scattered by the object and transmitted to the image capturing device. The infrared pass layer is adapted to pass the infrared light.

摘要： An optical fingerprint sensing module includes an image sensing device, a light source and a light shielding structure. The image sensing device is configured to sense light transmitted from a fingerprint of a finger on a display panel. The image sensing device includes a light sensing plane having a first geometric center. The light source includes a light emitting plane having a second geometric center. The first geometric center is separated from the second geometric center by a distance from 2 mm to 20 mm. The light shielding structure is disposed between the image sensing device and the light source. In examples, the optical fingerprint sensing module further includes a field angle controller to constrain light pass there through with a field angle of 5-60 degrees. A display device including an optical fingerprint sensing module is disclosed herein as well.

摘要： 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.
