Fingerprint Assembly, Electronic Device and Fingerprint Acquisition Method

摘要

Disclosed in the present application is a fingerprint module, applied to an electronic device including a screen and a fingerprint module. The fingerprint module is provided below a preset area of the screen. The screen is provided with a first polarizer. The fingerprint module includes a collimating lens and an optical fingerprint sensor, and the collimating lens is provided on the side of the optical fingerprint sensor close to the screen. The collimating lens is provided with a second polarizer, and polarization directions of the first polarizer and the second polarizer are consistent. The first polarizer and the second polarizer are configured to filter first light, and the first light is light, among light emitted from the screen in a first direction, reflected by the screen. The second polarizer is configured to filter the second light, and the second light is light emitted from the screen in a second direction.
