Title:
FINGERPRINT SENSING MODULE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/036326
Kind Code:
A1
Abstract:
An electronic device (100) and a fingerprint sensing module (200). The fingerprint sensing module (200) is applicable in being configured below a display panel (110) and comprises an image sensor (210) and a lens module (220). The image sensor (210) is configured below the display panel (110). The lens module (220) is configured between the image sensor (210) and the display panel (110). The display panel (110) is provided with an upper surface (S1) with which a finger of a user contacts, a lower surface (S3) facing the image sensor (210), and an electrode structure (116) arranged between the upper surface (S1) and the lower surface (S3). The lens module images the fingerprint of the finger in contact with the upper surface (S1) on the image sensor (210), the lens module (220) forms a virtual image (117) of the electrode structure (116), and the electrode structure (116) is arranged between the virtual image (117) and the image sensor (210). The fingerprint sensing module (200) prevents the electrode structure (116) from being imaged on the image sensor (210) and thus impacting the quality of a fingerprint image.
