Biometrics has been widely applied on various wearable devices and is developing toward full-screen, multi-finger secure fingerprint recognition. This technology is the first innovation of µLED, which provides both lighting and sensing that integrates bio-sensing devices and displays onto the same substrate and achieves thinner modules. This technique is the first interactive display technology in the industry to attain full-screen integration of fingerprint recognition, touch control, and µLED display. It meets the requirements for the information security of mobile and wearable devices.
