Abstract:
An electronic apparatus and a fingerprint sensing module suitable for being arranged below a display panel and including an image sensor disposed below the display panel, microlens array disposed between the image sensor and the display panel and including microlenses arranged in an array, and an ambient light blocking filter disposed between the image sensor and the microlens array and having light channels are provided. Each light channel is surrounded and formed by a light shielding body. Light beams from the microlenses are respectively transmitted to the image sensor through the light channels. The microlens array images a fingerprint of a finger contacting an upper surface of the display panel onto the image sensor, but does not image an electrode structure in the display panel onto the image sensor. The fingerprint sensing module can produce high-contrast fingerprint images and suppress moiré interference, and is less affected by ambient light.
