Title:
FINGERPRINT RECOGNITION APPARATUS AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/036101
Kind Code:
A1
Abstract:
A fingerprint recognition apparatus (300) and an electronic device (30), capable of improving the performance of the fingerprint recognition apparatus (300). The fingerprint recognition apparatus (300) is applied to a lower portion of a display screen (120). Each of a plurality of fingerprint recognition units (301) comprises: a microlens (310); at least two light shielding layers (220), each light shielding layer (220) being provided with light passing pores (2211, 2221, 2222, 2231) to form four light guide channels in different directions; and four pixel units (331, 332, 333, 334) respectively located at the bottoms of the four light guide channels. After fingerprint optical signals returned from a fingerprint above the display screen (120) are converged by means of the microlens (310), four target fingerprint optical signals in different directions are respectively transmitted to the four pixel units (331, 332, 333, 334) by means of the four light guide channels. Included angles of the four light guide channels relative to the display screen (120) are not completely the same. A plurality of groups of the four pixel units (331, 332, 333, 334) in the fingerprint recognition apparatus (300) receives fingerprint optical signals in four different directions and converts same into four fingerprint images, and the four fingerprint images are moved and reconstructed into a reconstructed image for fingerprint recognition.
