Abstract
The present application discloses a fingerprint identification device, a driving method thereof, a display panel and a display apparatus. The fingerprint identification device comprises a plurality of fingerprint identification units arranged in a matrix, a signal input line for loading a detection signal and a signal reading line for reading an identification signal which are in one-to-one correspondence with each column of fingerprint identification units. Each fingerprint identification unit comprises a fingerprint identification electrode, a first switch unit and a second switch unit connected to the signal input line respectively. The first switch unit is used for controlling an electrical conduction between the fingerprint identification electrode and the signal input line, the second switch unit is used for controlling an electrical conduction between the fingerprint identification electrode and the signal reading line.
