Title:
FINGERPRINT SENSING MODULE AND ELECTRONIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2021/042806
Kind Code:
A1
Abstract:
Provided in the present invention are a fingerprint sensing module and an electronic apparatus, the fingerprint sensing module being suitable for arranging below a display panel and comprising an image sensor, a micro-lens array, and an ambient light blocking filter. The image sensor is arranged below the display panel, and the micro-lens array is arranged between the image sensor and the display panel and comprises a plurality of micro-lenses arranged in an array. The ambient light blocking filter is arranged between the image sensor and the micro-lens array and is provided with a plurality of light channels, each light channel being surrounded by a light-shielding body, and light beams from the micro-lenses respectively being transmitted to the image sensor by means of the light channels. The micro-lens array images the fingerprint of a finger in contact with the upper surface of the display panel onto the image sensor, but will not image the electrode structure in the display panel onto the image sensor. The present fingerprint sensing module can produce high-contrast fingerprint images and suppress moiré interference, and is less affected by ambient light.
