Kyulux explains how narrow-spectrum Hyperfluorescence emission is more efficient than PHOLED emission

Second-generation OLED phosphorescence emission features an internal quantum efficiency of almost 100% - which would normally mean you cannot get more efficient than that.



As Kyulux explains in a recent post, though, phosphorescent suffers from a wide emission spectrum. In order to achieve a good color gamut (for which as narrow-spectrum emission as possible is best) display makers have to filter out the "tail" of the emission. This results in reduced brightness and efficiency.

Kyulux says it is on track to commercialize green Hyperfluorescence materials in 2023, red and blue in 2024

Kyulux gave a very upbeat presentation at SID Displayweek, during which it updated on its latest material specification and its commercialization plans.

Kyulux managed to increase the lifetime of its Hyperfluorescence emitter systems (which features an IQE of 100% and a narrow emission spectrum) quite dramatically in the past year its green material now offers a lifetime of 59,000 hours (LT95@1000 nits, top emission), while the red material is at 20,000 hours. The blue material has also increase from280 hours to 450 hours in the past year.

How machine learning and AI help find next-generation OLED materials

In recent years, we have seen accelerated OLED materials development, aided by software tools based on machine learning and Artificial Intelligence. This is an excellent development which contributes to the continued improvement in OLED efficiency, brightness and lifetime.

The promise of these new technologies is the ability to screen millions of possible molecules and systems quickly and efficiently. Materials scientists can then take the most promising candidates and perform real synthesis and experiments to confirm the operation in actual OLED devices.

Kyulux: our green Hyperfluoresence emitter is getting close to commercialization

Hyperfluoresence emitter system developer Kyulux announced that its green material is getting close to commercialization. The company is now working closely with OLED makers, preparing for early adoption.

Kyulux says that its green emitter has not only met the required performance of OLED panel makers, in terms of efficiency, lifetime and driving voltage - but has actually surpassed the performance of green phosphorescent emitters in top emission devices. The green HF device achieves higher current efficiency, longer lifetime and offers a narrow emission spectrum and can thus enable better chromaticity.

Kyulux reveals its latest TADF material performance

During SID Display Week 2021, Kyulux detailed its latest TADF material performance. The red and green materials are "close to commercialization", and the company reports "excellent progress" with its blue emitter.

Using simulations, Kyulux shows how its Hyperfluorescence system is more efficient than a comparable phosphorescence emitter. While both emitters feature pretty much the same EQE, the narrow spectrum of the HF system which results in higher light intensity and can enable more efficient displays - by around 10%, according to Kyulux.
