Abstract

The invention provides a fingerprint identification module, a display device and an electronic device. The fingerprint identification module comprises a collimator and a fingerprint sensing chip, wherein the collimator comprises a collimating layer and a filter layer plated on one side of the collimating layer, and the fingerprint sensing chip is fixed on one side of the collimating layer oppositeto the filter layer or on one side of the filter layer opposite to the collimating layer. The collimating structure can filter stray light of a specific wavelength to avoid stray light interfering with the normal operation of the fingerprint sensing chip, so that a filter coating is not required on the fingerprint sensing chip and the fingerprint sensing chip is prevented from bending under a force.
