Abstract
A fingerprint identification apparatus and an electronic device, capable of reducing under-screen space occupied by the fingerprint identification apparatus and facilitating assembly of the fingerprint identification apparatus. The fingerprint identification apparatus is applicable to an electronic device having a display screen, and includes: at least one optical fingerprint sensor; and a flexible circuit board electrically connected to the at least one optical fingerprint sensor; where a first adhesive layer is disposed at a periphery of the flexible circuit board for connecting the flexible circuit board and the display screen, so that the at least one optical fingerprint sensor is located under the display screen, the at least one optical fingerprint sensor is configured to receive a fingerprint detecting signal returned by reflection or scattering via a human finger on the display screen, and the fingerprint detecting signal is used to detect fingerprint information of the finger.
