摘要
An in‐screen ultra‐thin optical waveguide fingerprint sensing technology was demonstrated as an example of glass photonics (vs silicon photonics). It can be seamlessly integrated with OLED displays of phone devices or any other transparent surfaces for large area (or even full screen) in‐screen fingerprint sensing. Due to its unique optical designs with sensors facing the opposite side of the cover glasses, the fingerprint sensors can measure undistorted images with very high resistance to ambient light. The theory of optical designs and the system architecture of sensors are explained. A 1.1 inch sensor arrays were fabricated and integrated to OLED displays and transparent surfaces to verify the performances of the new fingerprint sensing technologies. It shows that the proposed system can successfully acquire the fingerprint images under 100,000Lux ambient light intensity.
