Kyulux and Wisechip Set to Release Commercial OLED Display Product Resulting from Collaboration

Kyulux, Inc. of Fukuoka, Japan, an OLED technology company, and WiseChip of Taipei, Taiwan, an OLED product maker, reported that the two companies intend to release a commercial display product using 4th generation HyperfluorescenceTM OLED light emission technology from Kyulux. Kyulux says that the new display will be the first commercial product using its new generation of organic compounds.

According to Kyulux, HyperfluorescenceTM is a 4th generation OLED technology that it says exceeds the performance of all previous generations of OLED emitters. Kyulux says that the first generation of fluorescent compounds employed as blue pixels in today’s cell phones and televisions are just 25% efficient and thus reduce a cell phone’s energy efficiency and battery life. While the second generation green and red emitters used in both televisions and cell phones are 100% efficient, they require an expensive rare metal Iridium. This second generation of OLED materials also yields an inferior color purity compared to the first generation.

OLEDs Using Hyperfluorescence from Kyulux Achieve 100% Efficiency without Rare Metals

On the other hand, fourth generation OLEDs using Hyperfluorescence enables 100% quantum efficiency in a completely organic molecule, without the use of rare heavy metals. Furthermore, the latest Hyperfluorescence technology couples the superior color purity of first generation OLED materials and the efficiency of second generation materials, enabling increased battery life or increased brightness without reducing color purity.

By 2017, WiseChip intends to begin offering commercial display products incorporating Hyperfluorescence. In doing so, Wisechip will become the first OLED display manufacturer to provide these 4th generation OLED displays for PMOLED applications.

Kyulux and WiseChip to Offer Monochromatic Displays

WiseChip and Kyulux, through a highly collaborative engineering partnership, rapidly increased the lifetime of Hyperfluorescence and TADF and OLED devices even at the high current densities needed for PMOLED applications. WiseChip and Kyulux will initially sell 4th generation monochromatic green and yellow displays and plans to commercially launch red, blue and white displays in the near future.

Professor Chihaya Adachi, Co-founder of Kyulux and inventor of Hyperfluorescence and TADF technologies said, “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.”

Dr. York Tsai, Vice President of R&D Engineering Division of WiseChip Semiconductor stated, “Our engineers have worked very hard together to deliver the world’s first product utilizing this disruptive new emitter technology.”

Hong Jun Wang, Chairman of WiseChip Semiconductor said, “Our close collaborative work with Kyulux will allow us to offer superior OLED devices to our current and future customers.”

Dr. Christopher Savoie, CEO of Kyulux stated, “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.”
