The present application provides a fingerprint sensor. The fingerprint sensor includes an array of a plurality of optical fibers. Each of the plurality of optical fibers has a first end and second end opposite to the first end. Each of the plurality of optical fibers is configured to allow an incident light to enter into the second end and an exit light to exit from the second end. Each of the plurality of optical fibers includes a fiber core; a fiber Bragg grating in the fiber core; and a reflective film on the first end.

Fingerprint sensor, display apparatus, method of detecting a fingerprint, and method of fabricating a fingerprint sensor

A device for fingerprint recognition, a manufacturing method therefor, and an electronic apparatus are provided. The method includes: forming fingerprint recognition units in multiple independent preset regions of a substrate, where the fingerprint recognition units each include a fingerprint recognition component and a light emitting component; partitioning the substrate along boundaries of the preset regions to separate the fingerprint recognition units from each other; and coupling the fingerprint recognition units after partition with corresponding control circuits, to make the fingerprint recognition component and the light emitting component of each fingerprint recognition unit be electrically connected to a corresponding control circuit coupled with the each fingerprint recognition unit. The fingerprint recognition unit and the control circuit coupled with each other serve together as the device for fingerprint recognition. The method is for manufacturing the device for fingerprint recognition.
