Micro Display and Bionic Eye

The main goal of Task 2 is to develop high-efficiency micro photodiodes/light emitting diodes and AM-OLEDs, on a flexible substrate, for the purpose of bionic eye applications, and also to demonstrate the functionality of prototype devices through clinical testing at the University of Texas Medical School. Towards that end, a variety of nano-materials and methods, such as the effects of localized surface plasmon resonance, photonic crystals and the control of fabrication and nanostructure, will be employed. Furthermore, flexible and transparent optoelectronic devices, novel approaches of hybridize inorganic and organic materials, such as damage-free sputtering and low temperature spray painting, will be incorporated within the project to improve efficiency and functionality.

Prof. S.J. Park (GIST), a member of the Korean Academy of Science and Technology, has developed high-efficiency GaN-based LEDs, ZnO LEDs, and Si quantum dot LEDs. He is co-chair of the SPIE International Conference on Solid-State Lighting. In this project, his contribution and specialization will be focused on the research and growth of micro LED arrays.

Prof. C. Tu (U.C. San Diego) is a fellow of the IEEE, America-Physical Society, and AVS. He introduced gas-source-MBE for III-V growth and has led research on hetero-epitaxy processes and other novel materials for LEDs. In this project, he will focus on the development of micro LED arrays.

Prof. A. Ignatiev (Univ. of Houston) is a member of the International Academy of Astronautics and has performed research on bionic eyes using ceramic photo detectors. He will closely collaborate with the University of Texas Medical School in clinical testing to ensure functionality and efficiency.

Prof. W. Lu (Ohio State Univ.) specializes in high-speed optoelectronics using GaN and III-V. His contribution and specialization in this project will pertain to the research of micro-display devices.

Prof. D.Y. Kim (GIST) has extensive experience in polymer electronics and photonics and has been published in over one-hundred academic journals such as Advanced Materials, JACS, Angewante Chemie, and others. His current research and interests include organic photovoltaic devices (OPV), organic light emitting diodes (OLED), organic thin film transistors (OTFT), azobenzene applications and the synthesis of organic electronic materials.

Prof. J.H. Jang (GIST) is focusing his research on highly efficient photo-detectors, oxide semiconductor devices and corresponding circuits. Because of his specialization, he will devote his time towards the design and fabrication of oxide-based AM-OLED backplanes and artificial retinas.
