Hyperfluorescence-capable OLED emitters are claimed to outperform all previous generations of OLED emitters, boasting 100% quantum efficiency in a completely organic molecule without requiring the use of rare heavy metals. This is to be compared with the first generation of fluorescent compounds used for blue pixels in today’s cell phones and televisions, only 25% efficient, and the second generation green and red emitters that are 100% efficient but rely on the expensive rare metal Iridium and Kyulux claims, also suffers from an inferior color purity compared to the first generation.
Hyperfluorescence OLED emitters are said to combine the superior color purity of gen 1 materials and the efficiency of gen 2 materials, allowing for increased battery life or increased brightness without sacrificing color purity.
WiseChip plans to begin offering commercial display products incorporating Hyperfluorescence by Q4 2017 and will become the first OLED display manufacturer to offer these 4th generation OLED displays for PMOLED applications.
Through a highly collaborative engineering partnership, WiseChip and Kyulux have been able to rapidly increase the lifetime of TADF ( thermally-activated delayed-fluorescence) and Hyperfluorescence OLED devices even at the high current densities required for PMOLED applications. WiseChip and Kyulux will initially offer 4th generation monochromatic yellow and green displays, with red, blue and white displays planned for commercial launch in the near future.
“It is fantastic to see that TADF technology will be deployed in a Hyperfluorescence commercial product. The technology, invented at Kyushu University in 2009 has seen a tremendous improvement in lifetime and efficiency over the years and is now poised to take over as the prevailing commercial OLED technology. I have particularly enjoyed watching this technology mature in the collaboration between Kyulux and WiseChip”, said Professor Chihaya Adachi, Co-founder of Kyulux and inventor of TADF and Hyperfluorescence technologies.
In a joint press release, Dr. Christopher Savoie, CEO of Kyulux added, “We are thrilled to be able to offer a TADF Hyperfluorescence product by year end. This would not have been possible without the skilled engineering capabilities of both companies. I am very proud of the joint team effort that has made this commercialization happen so quickly.”
