Abstract
The re is provided a fingerprint identification module, including a substrate having a fingerprint identification area and a peripheral area; a photoelectric sensing structure in the fingerprint identification area, and including pixel units; each pixel unit includes a thin film transistor having a gate electrode coupled to a corresponding gate line and a first electrode coupled to a corresponding signal sensing line; the fingerprint identification area includes a photosensitive region, the pixel unit in the photosensitive region further includes a photoelectric sensor including a third electrode, a photosensitive pattern and a fourth electrode which are sequentially stacked along a direction away from the substrate, and the third electrode is coupled to a second electrode of the thin film transistor in the same pixel unit as that where the photoelectric sensor is located; an area ratio of the photoelectric sensor to the pixel unit corresponding thereto ranges from 40% to 90%.
