The hottest Hong Kong University takes the lead in

Hong Kong University takes the lead in the research and development of OLED light-emitting materials, which is expected to break the monopoly of European and American patents

Hong Kong Wen Wei Po news: organic light-emitting diodes (OLEDs) are very important for the safety inspection of related display screens, TVs, food and screen related industries

at present, most OLEDs use the chemical complex of rare metal iridium as the light-emitting raw material, accounting for more than 90% of the market, and the relevant special charge first (which can also be applied when charging) is mainly monopolized by the United States and European countries, so that manufacturers often have to pay high patent fees

coordinated by the University of Hong Kong and combined with the interdisciplinary teams of five local universities, breakthroughs have been made in the past five years, including the use of gold and platinum compounds as light-emitting raw materials, the development of innovative display technologies and components, and the provision of solutions for the commercialization of relevant products with the intellectual property rights and patented technology of "paper enterprises lost 8billion Hong Kong products in 2018"

oled has the advantages of self illumination, wide viewing angle, fast reaction time, high efficiency, power saving, high brightness, very light and thin. It can be widely used in display screens, TVs, screens and even future "electronic paper" and other display products. It is a technology of global concern. However, at the industrial level, it faces problems such as iridium compound patent monopoly, which affects the cost

co ordinated by Professor Joseph Yam of the Department of chemistry of the University of Hong Kong, and in combination with interdisciplinary expert teams in chemistry, physics, materials science and engineering from the University of science and technology, the University of Hong Kong, the University of Hong Kong and the City University of Hong Kong, he has been supported by the "thematic research program" of the RGC in the past five years, and has made a number of important achievements in the field of OLED display and photovoltaic cells, and has also published as many as 260 highly influential academic articles

among them, Ren Yonghua's team focuses on the research and development of trivalent gold (Au (III)) compound luminescence as raw material, which is the world's first success in room temperature luminescence. In addition, experts in the cross school team also research and develop platinum as OLED raw material and large-area device luminescence display, breaking through existing restrictions, and integrating "Hong Kong made" OLED display knowledge patent new technology, which has the opportunity to change the ecology of the existing huge market

the University of Hong Kong refers to the strategy of promoting interdisciplinary cooperative research through the achievements of this interdisciplinary scientific research project, which not only creates world-class technology for Hong Kong, but also creates new opportunities for knowledge and technology transfer for local, mainland and international industrial partners. Its phase change latent heat is relatively large, promoting more downstream R & D and commercialization activities
