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.

WOLED application?

Given that LG's current WOLED stack loses color volume above 900 nits, does this HF green preserve color volume at higher luminance levels for TV application or is this mostly for smaller screen RGB-OLED applications (phones & tablets)?
