Materializing the future of OLEDs
Kyulux develops TADF/Hyperfluorescence™ emitters that take OLEDs to the next level - with higher efficiency, wider color gamuts and longer lifetimes.
The OLED market

OLED technology was invented in the 1980s by Kodak. OLED displays, based on organic emitting materials and a simple structure, offer the best image quality, coupled with a simple design, high degree of flexibility and efficiency.

 

No wonder that OLEDs have taken over the display industry, and are used in smartphones, wearables, tablets, laptops and TVs. The OLED market is currently evaluated at over $40 billion dollars, and is expected to continue to grow as demand for OLEDs is rising in applications such as TV, IT and automotive.

 

OLED technology enables unique solutions that were not available before, such as foldable, rollable and stretchable displays, transparent screens and high-brightness microdisplays for VR and AR. These exciting new displays are now entering the market and are set to change how we view the world.

Current OLED Challenges

The potential of OLED technology is currently hindered by the quality of available emitter systems. First generation OLED emitters, based on fluorescence emission, are limited in efficiency. Second generation phosphorescent emitters offer higher efficiency, but suffer from a wide emission spectrum and need to rely on heavy metals. Although second-generation phosphorescence is highly efficient, it suffers from a wide emission spectrum, low color purity, and it relies on expensive rare metals.

A key challenge for the OLED industry is developing a blue emitter system with high power efficiency, a long lifetime a narrow spectrum. The industry is still looking for a technology that combines the advantages of fluorescence and phosphorescence, and achieves high luminous efficiency, narrow emission spectrum, and high color purity. In particular, a new technology for blue emission is highly sought-after.

The Solution - Hyperfluorescence™ Emission

Kyulux’s Hyperfluorescence™ emission system combines first-gen fluorescence emitters with third-gen TADF emitters. TADF molecules have a small energy gap between the singlet and the triplet energy states (⊿Est). This enables up-conversion of excited energy from triplet to singlet spin. In Hyperfluorescence™ emission, the TADF molecules generate the excitons, and the excited energy transfers to fluorescent molecules. This integrates the best of both worlds: the high efficiency of TADF emission and the narrow spectrum of fluorescent emitters.


These two technologies enable the ultimate OLED emission that offers:

  • High efficiency (100% IQE)
  • Narrow spectrum
  • High intensity (60% higher than 2nd-Gen systems)
  • Metal free
  • Low cost
About Kyulux

Kyulux Inc., was established in 2015 to commercialize Hyperfluorescence™ technology originating at Kyushu University. Based on this technology, Kyulux develops the ultimate OLED emitter material system “Hyperfluorescence™” that offers high efficiency, long lifetime, high color purity and a cost-effective model, without relying on rare metals. To develop its materials, Kyulux uses a material discovery platform, based on a cutting-edge AI based prediction system called Kyumatic™, licensed exclusively from Harvard University.

The Kyumatic™ system has accumulated more than 200,000 quantum chemical calculations, material properties and device evaluation results. Kyulux improves on the unique abilities of Kyumatic™ and uses it to become the “Game Changer” of the OLED industry.

In 2023, Kyulux relocated its production management base to the “Ito Lab+”, a unique collaboration town of research, commercial, and residential facilities built adjacent to Kyulux’s headquarters​.　Kyulux handles its own production management, process development, and quality control as it accelerates its process and gets ready for the mass production of its OLED materials.

Kyulux’s mission is to create the future of OLED technology, based on its innovative materials, a leading team and advanced software technology. The company is developing an organic photonics ecosystem in Kyushu, to realize the full potential of OLED display and lighting technologies.
