Abstract: The present disclosure provides a fingerprint recognition device and a manufacturing method thereof, a display panel and a manufacturing method thereof, a display device, and a fingerprint recognition method. In the fingerprint recognition device of the present disclosure, the collimator transmits the collimated light reflected by the fingerprint and blocks the scattered light, so that the light emitted by the light emitting layer is reflected by the finger, and the approximately collimated reflected light can transmit through the collimator while the oblique light is blocked by the collimator. The sensor recognizes the ridges and valleys of the fingerprint according to the area through which the light is transmitted by the collimator. The fingerprint recognition device may be manufactured by a simple manufacturing process and have strong practicability, and is suitable for fingerprint collection and recognition in the display area of the organic light emitting diode display.

Abstract: A prism member of an authentication apparatus includes a living body contact surface configured to be in contact with the living body, and an imaging surface opposed to the living body contact surface and formed at a position generally parallel therewith. The prism member includes a reflection surface in contact with the living body contact surface and the imaging surface, to totally reflect light reflected from the former surface toward the latter surface. The reflection surface is at angle such that (i) light through the living body contact surface into the prism member does not reach to the reflection surface, and (ii) light from an inside of the prism member is totally reflected at the living body contact surface in an optical path running from the imaging surface and reaching the living body contact surface by way of the reflection surface. A first imaging unit captures a living-body reflected light.

Abstract: A biometric recognition system for a vehicle includes a support portion, a vein reader sensor disposed on the support portion, and a control member configured to control a function of the vehicle. The control member has a top surface and a bottom surface and defines an opening extending through the control member from the top surface to the bottom surface. The control member is moveable relative to the support portion to a first position. The opening is aligned with the vein reader sensor and the top surface is a first distance from the vein reader sensor when the control member is in the first position. The first distance is configured to optimize biometric verification of an operator's hand gripping the control member.

Abstract: An optical fingerprint identification module includes a casing, an image pickup assembly, a light-guiding diffusion layer, a light-collecting reflective layer, a press plate, a light source and an optical tunnel structure. The optical tunnel structure is located under the press plate and located over the image pickup assembly. The optical tunnel structure is penetrated through the light-collecting reflective layer and a part of the light-guiding diffusion layer. After a light beam emitted by the light source is introduced into the light-guiding diffusion layer, the light beam is guided and diffused by the light-guiding diffusion layer and collected and reflected by the light-collecting reflective layer. Consequently, the light beam is transferred between the light-guiding diffusion layer and the light-collecting reflective layer. After the light beam is irradiated on the press plate through the optical tunnel structure, the light beam is reflected to the image pickup assembly.

Abstract: An optical module includes a housing with a lighting mechanism, an aperture formed therein, and a window that frames a transparent surface adapted to contact a skin surface of a person, for example, a fingertip. The lighting mechanism provides light to illuminate the skin surface placed upon the transparent surface. A prism has a first side facing the lighting mechanism, a second side at the window, and a third side through which a dactylographic image exits the prism. One or more light reflecting surfaces are disposed within the housing to reflect the dactylographic image towards the housing aperture. The optical module is coupled to a mobile device having a camera, with the aperture of the housing aligning with a lens of the camera. The camera acquires the dactylographic image, and the mobile device adjusts this dactylographic image to produce a dactylographic image suitable for biometric matching.
