Profile bio

About Hyunjun Cho

I am a principal engineer at Samsung Display. I am proud that I have been one of the pioneers in flexible AMOLED display area. I have experienced the flexible display development from the immature research level to current mass production. The flexible AMOLED panels have been applied to iPhones since iPhone X and recent Samsung Galaxy series. In addition to the initiation of the flexible displays, I am currently focusing on component elements to realize foldable displays. I suggested several unique materials as supporting plate for folding action of the displays including both metals(SUS, Titanium) and non-metals(CFRP, GFRP).

Listed skills include Micro/Nano Fabrication, Flexible Displays, Amoleds, Thin Film Transistors, and 3 others.
