The team composed of Professor Zheng Jianhong, Liu Ruixiong, and Professor Lin Haowu from the Department of Chemistry of Tsinghua University in Taiwan has successfully made a major breakthrough in the research of "new double boron luminescent material components".
Organic light-emitting diodes (OLED) have attracted attention because of the adoption of iPhone X, but OLED panels are relatively expensive at present. The research team of Tsinghua University in Taiwan has developed a new generation of ultra-high-efficiency green OLED components. The component performance is the current world record, which is expected to promote Taiwan's panel and lighting industry has been upgraded, and outstanding research results were listed in the first international journal "Nature Photonics" in the field of optoelectronics on March 6.
Zheng Jianhong, a professor of chemistry at Tsinghua University, participated in the team's development of new OLEDs
Over the past 10 years, major foreign manufacturers have acquired a large number of OLED patented technologies, coupled with the adoption of OLED panels in mainstream mobile phones such as the iPhone X and Samsung, the LCD panel industry in Taiwan is currently facing a turning point in industrial transformation and technological upgrading, but the development of OLED panels in Taiwan is serious. Behind Japan and South Korea, the mainland has expanded its OLED panel industry in recent years, posing a serious threat to Taiwan's panel industry.
The team composed of Professor Zheng Jianhong, Liu Ruixiong, and Professor Lin Haowu from the Department of Materials Science and Technology of Tsinghua University in Taiwan has successfully made a major breakthrough in the research of "new double boron light-emitting material components". , and is expected to significantly reduce the cost of key luminescent materials, and promote the upgrading of the panel and lighting industries in Taiwan.
Zheng Jianhong said that the commercially available OLED light-emitting layer is composed of first-generation fluorescent materials or creative led screen second-generation phosphorescent materials. The luminous efficiency of fluorescent elements is about 5%, while that of phosphorescent elements is 20%. Currently, OLED materials are made of rare and precious metals such as iridium and platinum. As a result, the price of the panel is relatively expensive. With the support of the Ministry of Science and Technology, the Taiwan-Tsinghua University team developed a new dual-boron material that uses boron, a cheaper material, to break through the external quantum efficiency limit of traditional fluorescent and phosphorescent OLEDs.
According to Zheng Jianhong, with the team's proficient component manufacturing process and related technologies, an ultra-high-efficiency green OLED component has been produced, with an external quantum efficiency as high as 38%, which is much higher than the 5% of the first generation and 20 to 30% of the second generation. In addition, the synthesis steps are simplified and easy, and can be mass-produced, which greatly reduces the cost of key light-emitting materials. This research and development is mainly based on materials, which can be applied to various OLED components. Patent, it is estimated that the commercialization of the material can be completed within 2 years.
