TFT Fingerprint Sensor
- The ultra-high pixel density optical sensing technology can accurately detect weak light signals reflected by the finger. Fine fingerprints are detectable, as well as the heartbeat through the subtle gray-scale changes caused by the finger pulse, making identity verification more accurate.
- TFT structure optimization can reduce signal transmission interference and achieve the best signal-to-noise ratio of the optical sensor.
- The sensor’s sensitivity is improved by enhancing the intensity of optical signal reception, optimizing the sensor circuit, and using special optical film materials. As a result, integrated fingerprint scanners can meet the highest requirement standards of the FBI’s international safety standard certification.
