Sonavation announced a new technology that enables to embed an ultrasound fingerprint sensor behind an OLED display. Using this solution, mobile phone makers could enlarge the display area of the mobile device, as there will no no need for a separate fingerprint sensor.

Sonavation says that their "3D biometric ultrasound technology" is the only fingerprint authentication solution that offers complex-enough imaging through a full stack display.

Researchers from Kyushu University (led by Chihaya Adachi) are developing highly efficient blue OLED TADF (Thermally Activated Delayed Fluorescence, also called hyper-fluorescence) emitters.

Kyushu University now spun-off a new company, called Kyulux, backed by the University's QB Fund and the Japan Society for the Promotion of Science, to commercialize the TADF emitters. Kyulux raised ¥1.5 billion (around $13 million USD) and hopes to have their emitters ready by 2018.
