M-Era.net project acronym: Eco-OLED

Project duration: September 2020– August 2023.

Project coordinator – Prof. Jwo-Huei Jou (National Tsing-Hua University, Hsinchu, Taiwan)

Leader of the Latvian partner –Dr. Aivars Vembris (ISSP UL, Riga, Latvia)


The spectrum of sunlight can be imitated by organic light-emitting diodes (OLEDs). Replacing the current artificial lighting elements with OLEDs could be a way of preventing melancholy or even suicide, as the northern countries lack sunlight during the long winter. However, the difficulty of controlling the desired color and brightness at the same time has hindered the further commercialization of this invention for many years. We have finally been able to develop some new approaches to create natural-style emission that are not only color temperature- and brightness-adjustable, but also relatively high in terms of brightness and light quality. Specifically, we plan to achieve an all-friendly OLED with color temperature adjustable from 1400 K to 5500 K, SRI> 95, lifetime > 60,000 hours, power efficiency of 140 lm / W and to produce a commercially viable prototype OLED panel with a radiant area of 5 x 15 cm2 or 10 x 10 cm2 to meet market demands and increase the competitiveness of our lighting industry.

The international consortium includes four partners: Partner 1 (Taiwan) is responsible for the development of a high-efficiency light-emitting diode; Partner 2 from Latvia (ISSP UL) will investigate the light emission and electrical conductivity properties of the newly synthesized materials. The 3rd and 4th partners, from Latvia (RTU) and Lithuania respectively, will deal with the synthesis of second- and third-generation organic light-emitting molecules. The project envisages technological development up to TRL 4 level.
