At present, most OLEDs use chemical complexes of the rare metal iridium (Iridium) as light-emitting materials, accounting for more than 90% of the market, and related patents are mainly monopolized by the United States and European countries, causing manufacturers to pay high patent fees.

Coordinated by the University of Hong Kong and combined with the interdisciplinary teams of 5 local universities, breakthroughs have been made in the past 5 years, Indoor Foldable LED Mesh Curtain including the use of gold and platinum compounds as light-emitting materials, and the development of innovative display technologies and components. Independent property rights and patented technologies provide solutions for the commercialization of related products.

OLED has the advantages of self-illumination, wide viewing angle, fast response time, high efficiency, power saving, high brightness, very light and thin, etc. It can be widely used in display products such as display screens, TVs, mobile phone screens, and future “electronic paper”. The technology that has attracted much attention, but at the industrial level, it faces problems such as iridium compound patent monopoly, which affects costs.

Coordinated by Yam Wing-wah, chair professor of the Department of Chemistry of the University of Hong Kong, combined with an interdisciplinary expert team of chemistry, physics, materials science and engineering from HKUST, HKBU, PolyU and CityU, it has been funded by the RGC’s “Thematic Research Project” in the past 5 years to work on OLED A number of important achievements have been made in technical fields such as display and photovoltaic cells, and as many as 260 high-impact academic articles have been published.

Among them, Ren Yonghua’s team focused on the research and development of trivalent gold (Au(III)) compound luminescence as the raw material, and the world’s first successful luminescence at room temperature. In addition, experts in the cross-school team also developed platinum as the raw material for OLEDs and large-area device luminescence displays. Break through the existing limitations and integrate the “Hong Kong-made” OLED display knowledge and patented new technology, which has the opportunity to change the ecology of the existing huge market.

The University of Hong Kong pointed out that the results of this cross-university scientific research project promote the strategy of interdisciplinary collaborative research, create world-class technology for Hong Kong, and create new opportunities for knowledge and technology transfer for local, mainland and international industrial partners, and promote more downstream R&D and commercialization activities.
