Ultra-thin glass used for full roll-to-roll deposition of OLEDs

Ultra-thin glass (UTG) is an exciting material. It exhibits beneficial features known from rigid glass sheets like resistance against heat, UV-light and many chemicals as well as dimensional stability, high gas barrier performance and surface smoothness. Thanks to the thickness of only 200 µm or less, however, it also comes with benefits that are surprising for glass substrates, e.g. bendability and light weight – approx.
250 g/m² for 100 µm thick UTG.

Recently, various smartphone manufacturers have started to offer phones with foldable displays based on UTG. This high-priced application can recoup development costs of the UTG and finance the upscaling of production. In the medium term, this material should thus also become affordable for larger displays through to OLED light panels or even thin-film solar cells.
