Title:
FINGERPRINT DETECTION APPARATUS AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/007964
Kind Code:
A1
Abstract:
A fingerprint detection apparatus and an electronic device, the fingerprint detection apparatus being suitable for below a display screen comprising a fingerprint detection zone, and the fingerprint detection apparatus comprising: multiple fingerprint detection units (20), the size of each fingerprint detection unit and the distance between adjacent fingerprint detection units being determined according to relevant size parameters of each fingerprint detection unit or of the fingerprint detection zone; each fingerprint detection unit comprises from top to bottom: a micro lens array (210); at least one light blocking layer to form multiple inclined light guide channels corresponding to each micro-lens; an optical sensing pixel array (240), each optical sensing pixel respectively being used for receiving an optical signal aggregated by the micro lens and transmitted by means of the corresponding light guide channel so as to detect fingerprint information of a finger. The fingerprint detection apparatus and the electronic device are capable of using a smaller chip area to implement the same valid fingerprint identification field of view, thereby reducing costs.
