Developing More Effective Core Technology for Next-Generation Display

Kyung Hee University has been selected for the “Nanomaterials Core Technology Development” project


As part of the project, a research team organized by Kyung Hee University will undertake the “Development of Light Emitting Diode Materials and Devices of Halide-Based Perovskites for a Solution Process,” which will lead to a drastic improvement in efficiency and resolution of the next-generation display technology. The team is set to receive over 4.3 billion KRW in research funding in the next five years.

The “Nano-materials Core Technology Development” project, managed by National Research Foundation of Korea (NRF) and the Ministry of Science, ICT and Future Planning, aims to proactively respond to predicted market growth for nanomaterials in the future and to spur commercial application and technology transfer of latest technology.

Applying the principle of perovskite solar cells in reverse
Perovskite is a special metal oxide that can exhibit features of insulator, conductor, semiconductor, and superconductor depending on the condition it is under. Currently the perovskite solar cell is one of the most promising areas of technological development due to its rapidly improving efficiency and low production cost. When the principle of solar cell is applied in reverse, however, perovskite structures emit light with high efficiency, rather than absorbing light to produce electricity, which in turn has become a key research area for display application.


Professor Jong Wook Park of the Department of Chemical Engineering, the director of this project, said, “When you place a thin film between anode and cathode, the film emits characteristic light depending on the material of the film. We are experimenting with perovskite in this application that seems to have a great promise of high efficiency and low cost based on the exciton bonding energy that bounds an electron and an electron hole.”


MoU for technology transfer exchanged with four universities and six corporations
Professor Park said, “The uniqueness of our proposed research model and the positive results of initial experiments that had exceeded the expectation of NRF significantly raised the reliability of the proposal, leading to our selection for the project.”


This project will be led and managed by Kyung Hee University with the participation by Korea University, Ajou University, Hanbat National University, and Innox Corp. From Kyung Hee, Professors Jong Wook Park (Director), B. J. Park, Young-Chul Kim of the Department of Chemical Engineering, and Min-Chul Suh of the Department of Information Display will lead the research effort.

The research team has exchanged MoUs with the University of North Carolina, Kyoto University, Yamagata University, and the University of South China to furnish cooperative research relations in relevant areas. Six companies have so far signed up for technology transfer including LG Display, Innox Corp., Kyung-In Synthetic Co., AlphaChem Co. LTD., MaterialScience Co., and Dae Joo Electronic Materials Co. LTD that will lead to the commercial launch of next-generation display products. 


Professor Park said, “While it is possible to wirelessly offload batteries and storage system, a display device cannot be miniaturized beyond a certain point or wholly replaced, as visual input accounts for 75-80% of total human information intake. Advancement in display technology will be even more critical in the era of Industry 4.0, which explains the great commercial interest in the potential marketability of technologies spawned in this project. We will continue on with this line of research even after the completion of the current government project.”
