Problems solved by technology

With this technical solution, the overall light input of the fingerprint recognition device is small, the exposure time is long, the overall imaging quality is poor, and the recognition performance for dry fingers is not good.
At the same time, the thickness of the optical path in the fingerprint identification device is thick, which increases the processing difficulty and cost of the optical path, and is not conducive to the development of thinner and lighter fingerprint identification devices.

Abstract

The embodiment of the invention discloses a fingerprint recognition device and electronic equipment. The performance of the fingerprint recognition device can be improved. The fingerprint recognitiondevice is suitable for being arranged below a display screen to realize optical fingerprint recognition under the screen, the fingerprint recognition device comprises a plurality of fingerprint recognition units, and each fingerprint recognition unit comprises a micro lens; at least two light blocking layers, wherein each light blocking layer is provided with a light through hole to form two lightguide channels in different directions; the two pixel units are respectively positioned at the bottoms of the two light guide channels; wherein after fingerprint optical signals returned from a finger above the display screen are converged through the micro lens, two target fingerprint optical signals in different directions are transmitted to the two pixel units through the two light guide channels respectively. A plurality of groups of two pixel units in the fingerprint recognition device receive fingerprint optical signals in two different directions and convert the fingerprint optical signals into two fingerprint images, the two fingerprint images are moved and reconstructed into a reconstructed image, and the reconstructed image is used for fingerprint recognition.
