Abstract
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.
