LG Display's Kwon Se-Yeol senior researcher introduced the 77-inch transparent flexible OLED which had been introduced in June at IMID 2017 held in BEXCO, Busan on Aug. 30, and announced the applied technologies to realize this. Kwon Se-Yeol senior researcher mentioned, "OLED is self-luminous, so it can be manufactured with a thin thickness because it does not need a back light unit. The thinner the thickness, the more flexible the OLED can be so that it is easy to implement flexible displays with OLEDs." and forecasted. "It can be used in various fields such as signage and smart desk."

At iMiD 2017 in BEXCO, Busan on 28th, AP Systems announced that it succeeded in developing 1000ppi FMM with USPL (ultra-short pulse laser). Since FMM plays a role of depositing pixels and RGB organic materials, FMM serves as a factor that determines resolution and yield of OLED. At present, FMM is mainly manufactured by etching method. This method has a problem that a shadow phenomenon due to the precision, thickness, and weight of the fine pattern occurs, in order to solve this problem, various FMM manufacturing processes such as laser processing and electro-forming have been developed.

Cambridge (UK), 31 July 2017 – FlexEnable, the leader in the development and industrialization of organic electronics for flexible displays and sensors, has signed a technology transfer and license agreement with Truly Semiconductors, one of the leading display makers in China. The deal aims to bring FlexEnable’s flexible organic liquid crystal display (OLCD) technology into mass production on Truly’s lines within 2018.

Manufacturing technology has been developed to quickly fabricate OLED. The Korea Research Foundation (KFRI) announced the Yun, Hongseok research team at Hanbat National University has developed a high-speed transfer technology that can effectively transfer multiple thin OLED layers to desired locations through high-pressure air jet injection.
