We have developed a novel full-screen capacitive fingerprint and touch sensor, which can scan and detect a user’s fingerprint anywhere on a display, using Low Temperature Poly-silicon (LTPS) technology and Analog Front End Integrated Circuit (AFE IC) technology. Due to its excellent detection performance, the sensor can detect high quality fingerprint image even through the cover glass.
