Abstract
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.
