UK-based optical thin-film developer Artemis announced a partnership with Plessey Semiconductor to co-develop HUD displays that use Plessey's GaN-on-Si MicroLEDs and Artemis' thin-film coatings for HUDs.

Plessey recently announced its new licensing platform and also its intentions to bring a monolithic MicroLED display to the market in H1 2018 . Plessey demonstrated an HUD prototype powered by its MicroLED display.

Researchers from Korea's Ulsan National Institute of Science and Technology (UNIST) and Sungkyunkwan University contact lenses that has an ultra-sensitive blood glucose sensor that analyze tears.

To the wearer, the contact lens appear like regular ones, but when the sensor detects fluctuations in the blood glucose level, it lights up the chipset and an embedded micro-LED that stays lit if the blood glucose level is normal, so the wearer understand his blood levels. The contact lens are powered by wirelessly transmitted electricity.
