SENSOR AND ELECTRONIC APPARATUS FOR FINGERPRINT RECOGNITION

WIPO Patent Application WO/2019/143034

A1

A fingerprint sensor and an electronic device are provided. The fingerprint sensor includes a refractive member configured to refract light into a path toward at least one optical sensor, wherein the at least one optical sensor is configured to obtain the light, and a guide member disposed between the refractive member and the at least one optical sensor and configured to provide the path so that the refracted light is transmitted to the at least one optical sensor. The electronic device includes transparent cover; light source configured to output light toward transparent cover; refractive member configured to refract light into path toward at least one optical sensor; wherein at least one optical sensor is configured to obtain light; and guide member disposed between refractive member and at least one optical sensor and configured to provide path so that refracted light is transmitted to at least one optical sensor.
