CINNO Research Industry Information, on April 24, 2020, Kyulux Co., Ltd. officially started mass production and shipment of the world's first TADF / Hyperfluorescence ™ luminescent material to WiseChip Optoelectronics Co., Ltd. in Taiwan.
WiseChip launched a 2.7-inch yellow PMOLED display in October 2019. The product uses Kyulux Corporation's Hyperfluorescence ™ technology, becoming the world's first Hyperfluorescence ™ display and attracting attention.
WiseChip is a world-leading PMOLED manufacturer with strong OLED technology. By using Hyperfluorescence ™ material from Kyulux Co., Ltd., it has successfully achieved high-efficiency, high-quality, and low-power display performance. WiseChip's goal is to enter the medical, industrial, and electronic markets through the new TADF / HF PMOLEDs. It is expected that the future will also make a difference in the wearable device and portable home appliance markets.
Kyulux Co., Ltd. is proud of the world's first successful shipment of TADF / Hyperfluprescence ™ materials. For OLED, Kyulux Co., Ltd. will continue to provide high-efficiency, high-purity, long-life luminescent materials with cost competitive advantages, leading the development of global TADF and Hyperfluorescence ™ technology.
The fourth generation of super fluorescent TADF material technology
OLED light-emitting materials can be divided into fluorescent light-emitting materials and phosphorescent light-emitting materials according to the light-emitting mode.
The first-generation fluorescent luminescent materials have low cost but poor luminous efficiency. Through the author's research on the luminescence mechanism, only 25% of the fluorescent light-emitting materials can be used to emit light in the electrical energy generated by the voltage, and the remaining 75% is converted into heat energy for release.
At the same time, by injecting heavy metal atoms such as iridium Ir, platinum Pt, europium Eu, osmium Os, etc., the second-generation phosphorescent luminescent materials can greatly improve the luminous efficiency of light energy, and can convert waste of fluorescent materials into 75% of thermal energy. All energy is converted into light energy. Therefore, the luminous efficiency of the OLED device is greatly improved, and this is also a widely used luminescent material in the industry.
The third-generation thermally activated delayed fluorescent material TADF is a new type of thermally activated delayed fluorescent material comparable to the second-generation phosphorescent luminescent material. The most direct benefit of this luminescent material is that it can be used unlike the second-generation phosphorescent luminescent material. Inject heavy metal atoms such as iridium Ir, platinum Pt, europium Eu, osmium Os, etc., thereby saving manufacturing costs; in addition, high-efficiency TADF thermal activation delayed fluorescent materials will be commercialized in the future for display or smart phone products, with reduced power Loss and extend battery life.
In 2014, Kyushu University developed a new light-emitting principle called super-fluorescence technology. The so-called super-fluorescence is the combination of fluorescent materials and TADF. Prior to this, cost and efficiency were the two key points of luminescent materials. In fact, fluorescent materials are Very pure color, TADF gathers the colors together on one hand, the combination is one stone and three birds, the energy in the material is transferred in T1 and S1, the energy is transferred to the fluorescence in the vicinity, and it does not emit light by itself, but collect these The energy input into the fluorescent material, through the luminescent material of the luminescent layer, and then vapor deposition can be achieved.
About Kyulux
Kyulux was established in Japan in 2015 and is committed to developing the next generation of OLED luminescent materials.
Based on the exclusive licensing technology of Kyushu University, Kyulux developed the fourth generation of super-fluorescent TADF material technology, which is durable, cost-effective and has a quantum efficiency of 100% for organic molecules. It can achieve 100% luminous efficiency without the use of rare heavy metals.
At the same time Kyulux is developing red, green, yellow and blue super-fluorescent luminescent materials.
In 2016, Kyulux raised US $ 13.5 million from companies such as Samsung, LG, Japan Display, and JOLED, and announced in 2019 that it had raised US $ 31.8 million in Series B financing.
