Abstract:
The present disclosure discloses a fingerprint recognition device, a display substrate and a display apparatus. The fingerprint recognition device includes: at least one fingerprint detection component; at least one fingerprint recognition signal line, the fingerprint detection component outputs a detection current to the fingerprint recognition signal line; at least one noise reduction circuit serially coupled in the fingerprint recognition signal line, the noise reduction circuit being a resistive component; and a fingerprint determination circuit coupled to the fingerprint recognition signal line, configured to determine a morphology of a fingerprint according to a current signal, subjected to a noise reduction by the noise reduction circuit and transmitted by the fingerprint recognition signal line. The fingerprint recognition device can filter out the current generated by coupling the fingerprint recognition signal line with other data lines, the interference with the detection current is reduced, the accuracy of the fingerprint recognition is improved.
