Abstract

Embodiments of the present application relate to fingerprint identification and anti-counterfeiting methods, devices and electronic equipment. The fingerprint identification device is arranged under the display screen of the electronic device, and the fingerprint detection area of ​​the display screen includes a central area and a surrounding area that do not overlap with each other. The fingerprint identification device includes: an optical path guiding structure for guiding the return optical signal sensor, the return light signal is the light signal returned after the light emitted by the light-emitting display pixels in the fingerprint detection area irradiates the finger, the light-emitting display pixels in the central area emit monochromatic light to illuminate the finger, and the light-emitting display pixels in the surrounding area emit a variety of colors of light that are spatially spaced apart to irradiate the finger; the optical sensor is used to receive the light signal passing through the light path guiding structure to obtain the fingerprint image of the finger, and the central part of the fingerprint image corresponding to the central area is used for For fingerprint identification, the surrounding part corresponding to the surrounding area in the fingerprint image is used for fingerprint anti-counterfeiting authentication.

Description

technical field [0001] The present application relates to the field of biometric identification, in particular to methods, devices and electronic equipment for fingerprint identification and anti-counterfeiting. Background technique [0002] With the gradual popularization of mobile phones with under-screen optical fingerprint solutions, higher requirements are put forward for the anti-counterfeiting of under-screen optical fingerprints. However, the under-screen optical fingerprint technology that has been released so far has limited anti-counterfeiting functions, and most of them have almost no anti-counterfeiting functions. [0003] For example, there are currently two main types of under-display optical fingerprint sensor technologies. The first is an off-screen optical fingerprint recognition technology based on a periodic microhole array, which is susceptible to Moiré fringes. The second is based on the integrated micro-lens under-screen optical fingerprint recogniti...
