Abstract
A recognition device, a fingerprint recognition device and a fingerprint recognition apparatus are provided, and the fingerprint recognition device includes: a detection substrate provided with fingerprint detector units; a light barrier which is provided at a side, provided with the fingerprint detector units, of the detection substrate, and provided with light through holes corresponding to the fingerprint detector units; a cover plate which is provided at a side, facing away from the detection substrate, of the light barrier, and includes a light exit surface facing the light barrier and a touch surface facing away from the light barrier; and a light source for emitting light to the cover plate. Each fingerprint detector unit is configured to output an electrical signal according to an intensity of light incident on the fingerprint detector unit, after the light passes through the light through hole corresponding to the fingerprint detector unit.
