Upscaling of blue elementary emitter to revolutionize OLED manufacturing

Project description

Bringing blue to OLED displays

Blue light has long been the weak link in OLED technology. Current blue emitters are inefficient, draining batteries, increasing energy use and causing screen ‘burn-in’ that shortens device lifespan. These drawbacks have kept OLED TV adoption low. Despite years of research, a stable and efficient blue emitter for large-scale production remains out of reach. The EIC-funded beeUP project is helping beeOLED bring this breakthrough to market. Specifically, beeOLED’s deep-blue emitter, based on divalent europium (Eu2+) and trivalent Cerium(Ce3+), delivers brighter, longer-lasting and more energy-efficient OLED displays. By stabilising Eu2+ and Ce3+ for the first time, the team has created patented technology ready for industrial scaling, marking a major step towards more sustainable, high-performance screens.

Objective

In OLED, blue has been the critical weak point ever since the commercialization of OLED displays. Because of the inefficient blue emitters still used today, OLED TVs receive poor energy star ratings and smartphones run out of battery quickly. Additionally, their poor stability results in “burn in”, which, for example, requires smart watches to be dimmed down most of the time. Market penetration of OLED in TV is therefore stuck at 3-5%. Given the importance of blue emitters for the OLED market (and the resulting commercial attractiveness), numerous attempts have been made in the last 20 years to solve this problem. However, neither startups nor large corporates have been able to present a solution viable for high-volume manufacturing. Especially scaling up a promising material from laboratory scale to mass production is still a major hurdle for most solutions.
beeOLED is solving the last big problem of the OLED industry - a highly efficient, long lasting, deep-blue emitter. Building on 20 years of OLED industry experience, the founding team of beeOLED has rediscovered an almost forgotten star amongst the display materials: divalent Europium (Eu2+). Leveraging the latest advances in Europium chemistry, beeOLED managed, for the first time ever, to stabilize Eu2+ such that it becomes usable in OLEDs. The fundamental concept is protected by several base patents, solely owned by beeOLED. beeOLED’s technology enables OLED displays with significantly improved efficiency, brightness and chemical stability at lower overall costs due to a less complex device structure.
The overall OLED materials market is valued today at US$1.7bn/y with a CAGR of 15%. Initially, beeOLED will focus on the OLED emitter dopant materials, which is a highly promising market with strong profit margins. After successfully scaling up the production, the goal of beeOLED is to achieve a dominant position in this market with the vision to become the No .1 OLED emitter material provider in 2030.
