Abstract
A fingerprint identification panel and a preparation method thereof, a driving method and a fingerprint identification device are provided. A driving electrode and a sensing electrode are provided between a base substrate and a cover plate, the driving electrode and the sensing electrode intersecting with each other define an identification unit, a photoelectric converter unit is provided in the identification unit. The photoelectric converter unit includes a light shielding electrode, a second electrode, and a photoelectric converter layer located between the light shielding electrode and the second electrode. The light shielding electrode is located between the photoelectric converter layer and the base substrate. The light shielding electrode includes a first electrode, one of the first electrode and the second electrode is electrically connected with the driving electrode, and the other of the first electrode and the second electrode is electrically connected with the sensing electrode.
