Enabling a Commercially Viable Long Lifespan and High-Efficiency Omni-Friendly OLED Lighting Source with G2 and G3 Emitters - Eco-OLED

Project summary

We invented the first natural light-style OLED with the incorporation of a nano-layer of carrier modulation material between two sunlight complementary emission layers. It could be a cure to melancholy or even suicidal tendencies that arise due to the lack of sunlight during the long winters in northern countries. However, the difficulty in a simultaneous control of the chromaticity and luminance has prevented this invention from further commercialization for many years. We have eventually been able to devise some new approaches to generate natural-style emission that is not only color temperature and luminance tunable, but also relatively high in the obtainable brightness and light quality. Specifically, we plan to achieve an omni-friendly OLED with a color temperature tunable from 1,400 K to 5,500 K, an SRI of > 95, a lifetime > 60,000 hours, a power efficacy of 140 lm/W, and a commercially viable prototype of OLED panel with an emitting area of 5 x 15 cm2 or 10 x10 cm2.
