Mitsui Chemicals announced that its Structbond XMF-T transparent OLED sealant is used in LGD's flexible OLED displays (the 6" 720p plastic-based flexible OLED as used in the G Flex curved smartphone).
Mitsui says that their sealing material offers high barrier properties, moisture resistance, transparency and process manageability.
I posted a hands-on review of LG's G Flex mobile phone a couple of months ago. This is a unique and cool device, a great Android phone with a definite "wow factor". It's a bit too large for my liking, but I actually really like it.
