Abstract

The invention discloses a fingerprint recognition assembly, electronic equipment and a fingerprint recognition method, and belongs to the technical field of electronic equipment. The fingerprint recognition assembly comprises a substrate; a photosensitive layer is arranged on the substrate, the photosensitive layer comprises a visible light receiving area and at least one infrared light receivingarea, the visible light receiving area is used for receiving visible light signals, and the infrared light receiving area is used for receiving infrared light signals; the optical signal guiding structure is arranged above the photosensitive layer and specifically comprises a visible light filtering film layer and an infrared light filtering film layer; the visible light filtering film layer is opposite to the infrared light receiving area and is used for filtering visible light signals and transmitting infrared light signals; the infrared light filtering film layer is opposite to the visiblelight receiving area and used for filtering out infrared light signals and transmitting the visible light signals. According to the fingerprint recognition assembly provided by the embodiment of the invention, the human body living body recognition can be carried out by receiving the infrared light signal radiated by the finger, so that the safety and reliability of fingerprint recognition are greatly improved.

Description

technical field [0001] The application belongs to the technical field of electronic equipment, and in particular relates to a fingerprint identification component, electronic equipment and a fingerprint identification method. Background technique [0002] With the rapid development of the electronic industry, the functions of electronic equipment are becoming more and more powerful. In order to improve the intelligence of electronic devices, fingerprint identification technology has been widely used in electronic devices in recent years. [0003] In the prior art, a fingerprint recognition device on an electronic device usually realizes a fingerprint unlocking function by collecting an optical signal carrying fingerprint information. However, when the fingerprint information of the finger is copied by the fingerprint film, the fingerprint film can also reflect light to generate an optical signal carrying the fingerprint information, which is then collected by the fingerprin...
