| titleOfInvention | An optical fingerprint identification device, its fingerprint identification method, and a display device |
| abstract | Embodiments of the present invention provide an optical fingerprint identification device, a fingerprint identification method thereof, and a display device, which relate to the technical field of fingerprint identification, can reduce the thickness of the optical fingerprint identification device, and reduce the cost of the optical fingerprint identification device. The optical fingerprint identification device comprises: a cover plate; a piezoluminescent layer arranged under the cover plate, and the state of emitting light of the piezoluminescent layer changes when pressed to emit light of a certain wavelength; an optical sensing layer , used to detect the light reflected by the finger emitted by the piezoluminescent layer; a light-shielding pattern layer, arranged between the optical sensing layer and the piezoluminescent layer, used to block the light emitted by the piezoluminescent layer The light is directly irradiated on the optical sensing layer. Used in optical fingerprint identification devices. |
