Title:
OPTICAL ID SENSING USING ILLUMINATION LIGHT SOURCES POSITIONED AT A PERIPHERY OF A DISPLAY SCREEN
Document Type and Number:
WIPO Patent Application WO/2020/206919
Kind Code:
A1
Abstract:
An apparatus for capturing biometric pattern is applicable to an electronic device having a display screen, and the display screen includes a transparent layer (5013) having an edge side and a display illumination layer (5015) under the transparent layer (5013). The apparatus includes an optical ID sensing module (5023) for being disposed under the display illumination layer (5015) of the display screen and configured to form an image of a fingerprint pattern or a palmprint pattern of a hand of a user. The apparatus further includes a light source (5025) for being disposed at an edge side of the transparent layer (5013) of the display screen, and the light source (5025) is configured to emit a light beam to be coupled into the transparent layer (5013) through the edge side. A portion of the light beam may be through the edge side. A portion of the light beam may be transmitted to illuminate the hand for imaging the fingerprint pattern or the palmprint pattern by the optical ID sensing module (5023).
