Title:
FINGERPRINT IDENTIFICATION APPARATUS, DISPLAY PANEL AND FABRICATION METHOD THEREFOR, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/205646
Kind Code:
A1
Abstract:
A fingerprint identification apparatus, a display panel and a fabrication method therefor, and a display apparatus. The fingerprint identification apparatus (10) comprises a fingerprint sensor (3), a porous diaphragm (2), and a first shielding structure (4). The fingerprint sensor (3) comprises a plurality of sensing units (301); the porous diaphragm (2) is provided at a light incident side of the fingerprint sensor (3) and comprises a hole (5), the hole (5) allowing light to pass therethrough to be incident on at least one sensing unit (301) of the fingerprint sensor (3); the first shielding structure (4) is provided at a side of the porous diaphragm (2) that faces away from the fingerprint sensor (3) and at least partially surrounds the hole (5). The fingerprint identification apparatus (10) may prevent more interfering light from entering the sensing units (301) by means of the hole (5), thus improving the precision of the fingerprint identification apparatus (10).
