The Excellence of National R&D Top 100 in 2019

Prof. Hyun Jae Kim’s research won the best performance award among "The Excellence of National R&D top 100 in 2019“

 

The research performed by Prof. Hyun Jae Kim (School of Electrical and Electronic Engineering, Associate Dean of Academic Affairs in UIC) research team won the best performance award among "The Excellence of National R&D top 100“. The Ministry of Science and ICT and the Korea Institute of Science and Technology Evaluation and Planning has selected the Excellence of National R&D top 100 every year since 2006 to enhance public understanding and interest in the science and technology and to promote the pride of scientists and engineers. Out of the 63,000 tasks that were carried out under government support, 949 candidates recommended by the Office of Government Administration were evaluated. A total of 52 experts from industry, academia, and research institutes participated in evaluation and assessed their qualitative excellence, including the effects on science and technology development and economic and social ripple effects. Finally, 100 achievements were selected after public verification by the public. Among those 100 achievements, only 12 (two for each of the six categories) were selected as the best performance award.

In this research, Prof. Hyun Jae Kim and his research team focused on developing intelligent display-based technology through embedded display panel of oxide-based based complementary metal oxide semiconductor (CMOS) image sensors. It was a part of Basic Research Project in Science and Technology and supported by government institute, National Research Foundation of Korea (NRF). Under the guidance of Prof. Hyun Jae Kim, Ph. D. candidate student Jin hyuk Lee and 12 students carried out this research. As a result, they achieved 13 research papers, 6 patents, and technology transfer through the development of oxide based thin film transistor (TFT) and photodiode.

In order for South Korea’s display industry to survive the market competition with China, which is chasing after by South Korea with fast speed, the technological gap should be widened further through a new strategy to develop high value-added display technologies that overturn the existing display paradigm. Accordingly, intelligent displays are receiving attention as new paradigm displays, which recognize various signals of users, exchange information, and detect their surroundings and operate according to the situation. In that sense, Prof. Hyun Jae Kim’s research team developed a technology that oxide-based CMOS image sensor is embedded into a panel (CIP, CMOS image-sensor on panel) so that displays can recognize external environments and provide customized screens for situations. Therefore, the research team developed the original technology for manufacturing unit elements for CMOS image sensors by simultaneously developing oxide-based n-type and p-type TFTs and optical diodes, which could develop into a key technology that could be applied to flexible and wearable electronic devices as well as to display. If Korea preempts the next-generation display market through such intelligent display research and development, it can further strengthen the domestic display company's position in the global market.
