Earlier this month Samsung announced the Galaxy Z Flip, its 2nd foldable smartphone - and the 6.7" 1080x2636 inward foldable HDR "Dynamic AMOLED" display uses a flexible glass cover, as opposed to SDC's previous foldable OLEDs that used a flexible polyimide cover.

Samsung now says that it is branding its ultra-thin-glass foldable OLEDs as Samsung UTG. I'm not sure what to say regarding Samsung's slogan "Tough, yet Tender" which seems to be taken out of a completely different industry.

In any case, Samsung says that its UTG cover enables it to meet more demanding customer needs compared to its 1st-gen Polyimide cover material. Samsung syas that its foldable glass, developed since 2013 in collaboration with a partner in Korea (Dowoo Insys, who processes Schott's ultra thin glass), is 30um thick and is produced using an intensifying process to enhance its flexibility and durability. In the process, the UTG is injected with a special material up to an undisclosed depth to achieve a consistent hardness.
