摘要
Provided are an under-screen biometric identification apparatus and an electronic device. The under-screen biometric identification apparatus includes: a lens disposed under a display screen for receiving an optical signal from above the display screen and formed by reflection of a human finger, where the optical signal is used to detect biometric information of the finger; a lens barrel, where the lens is fixed in the lens barrel; and a sensing chip disposed under the lens barrel for imaging based on an optical signal passing through the lens, where a distance between a photosurface of the sensing chip and an imaging surface of the lens is greater than or equal to a preset value. An under-screen biometric identification apparatus and an electronic device provided in embodiments of the present application can improve the efficiency of under-screen biometric identification.
