Title:
FINGERPRINT IDENTIFICATION STRUCTURE AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/024538
Kind Code:
A1
Abstract:
A fingerprint identification structure and a manufacturing method therefor, and an electronic device. The fingerprint identification structure comprises: a base substrate (11); a plurality of first touch control electrodes (12) and a plurality of second touch control electrodes (14) on the base substrate (11), the plurality of first touch control electrodes (12) being crossed with the plurality of second touch control electrodes (14); and a plurality of photosensitive patterns (13) which is respectively and correspondingly provided at the positions where the plurality of first touch control electrodes (12) and the plurality of second touch control electrodes (14) are crossed, and separates the second touch control electrodes (14) from the first touch control electrodes (12). More sensitive fingerprint identification can be achieved by mean of the first touch control electrodes (12), the second touch control electrodes (14), and the photosensitive patterns (13) therebetween, such that the requirements for distances from a finger to the first touch control electrodes (12) and the second touch control electrodes (14) are reduced.
