Abstract:We are using smartphone with AMOLED displays on PI substrate. Basically, we need the technologies for PI substrate, gas barrier, TFT, planarization, bank, OLED, encapsulation, touch sensor and top transparent encapsulation for foldable AMOLED. In this talk I will review the whole process for the foldable AMOLED display from PI substrate process to detach of the AMOLED display. Especially I will focus on the TFT technologies on PI substrate with LTPS and oxide semiconductors which are currently used for AMOLED display manufacturing.
Biography:Jin Jang is a Chair Professor at the Advanced Display Research Center and Department of Information Display of Kyung Hee University. His current research programs are in oxide and LTPS TFTs for displays, TFT circuits and TFT application to sensors, Micro-LED and flexible AMOLED. He invented the first full color AMLCD on plastic substrate, flexible AMOLED and some new device structures using oxide semiconductors. He is the author or co-author of over 1,000 technical publications of which over 650 are in SCI Journals such as Nature, Advanced Materials, Advanced Functional Materials, Energy Environmental Science, Applied Physics Letters, IEEE Electron Device Letters and IEEE TED. He is currently a Director of Advanced Display Research Center (ADRC) and had served as Program Chair of SID Symposium 2007 and General Chair of SID Display Week in 2009 and General Chair of IMID 2012, 2013. He is a Fellow of SID and he was awarded George Smith Award from IEEE in 2012, Slotto Owaki Prize from SID in 2015 and Ho-Am Award in 2017.
