“Advances in the development of flexible AMOLED display and end-product innovations”

Speaker: Ze Yuan, Deputy General Manager, Frontier Research Center, Royole


Flexible AMOLED technology is setting the stage for end-product innovations to come, exemplified by the great attention it has gained in the consumer market over the past year. The speaker will discuss selective topics in the development of flexible AMOLED display modules, which will further enhance the overall performance and reliability of the display. Beyond that, other examples of flexible electronics technologies and related end-product innovations will also be described.


Ze Yuan currently works at Royole Corporation, a company working on consumer products and business solutions associated with flexible displays and sensors. He is the Deputy General Manager of the Frontier Research Center at Royole where he is responsible for the development of novel displays, sensors, and other component R&D in support of consumer product innovations.

“AGC products for wearable devices -Durable and stretchable fluoroelastomer “AFLAS” and high moisture permeable polyurethane adhesive”

Speaker: Shinji Wada, Research and Development Chemist, AGC Group 


The AGC Group has five business fields; glass, electronics, chemicals, ceramics and biotechnology. Through world-leading technologies and expertise developed over more than 110 years of innovation, we have been offering a diverse lineup of products to the customers all over the world. In chemicals division, we are manufacturing a variety of products such as Chlor & Alkali materials, Fluoro materials and Polyurethane materials.

This time I will introduce two products for wearable devices; Durable stretchable fluroelastomer “AFLAS” and High moisture permeable polyurethane adhesive.

AFLAS is so called “FEPM”, the copolymer of tetrafluoroethylene and propylene, showing unique properties over a conventional FKM-type fluoroelastomer or silicone elastomer; heat resistance, chemical resistance, electric properties and high steam & odor resistance. These are the reasons why AFLAS has been used for a long time in the industries like Oil & Gas, Chemical processing, Automotive, Wire & Cable, Food handling, and Pharmaceutical applications. Furthermore, its fields are expanding to robotics application. We have also developed foamed-type stretchable AFLAS, as durability is kept. We believe these durable and stretchable properties would be useful for wearable devices.

Our polyurethane comprising high molecular weight polyether polyol, works as a pressure sensitive adhesive (PSA) with higher moisture-permeability than silicon PSA. Appropriate peel strength and high moisture permeability enables comfortable feeling even it touches on the skin for a long time. Skin would not be macerated, and the amount of stratum corneum peed off from the skin would be reduced. We believe this would be a suitable adhesive for connecting wearable devices to the body.


Shinji Wada received his B.S. and M.S. degree in chemistry and biotechnology from University of Tokyo in 2008. He joined AGC Inc. in 2008 and started working as a product development researcher in fluoropolymer development division. From 2015 to 2017 he stayed at University of Chicago as a visiting scholar and developed new polymerization method of fluoropolymers with organometallic catalysts. He has been in charge of the development of new fluoropolymers and composites, polymer manufacturing process, and looking for new applications over more than 10 years. Currently he is challenging to develop the fluoropolymer-based composites and find new applications.
