Optical fingerprint sensor mainly uses the principle of light refraction and reflection to collect fingerprint images. Put the finger on the optical lens, under the irradiation of the built-in light source, the light is shot from the bottom to the prism, and is emitted through the prism, and the Ang

The advantages of the optical fingerprint sensor module are mainly strong anti-static ability, good system stability, long service life, particularly high sensitivity, and can provide high-resolution fingerprint images, and the technology is also the most mature.
