Samsung finally unfurls its folding phone screen prototype

Denison went into a little detail on the mechanics of building the Infinity Flex Display. Obviously, glass isn’t particularly flexible, so Samsung abandoned it in favor of a new material that, according to Denison, is “an advanced composite polymer that’s both flexible and tough.” That display is made up of a cover window, shock-absorbent film, polarizer and backplane, which are all made to bend, and are stuck together with a new type of foldable adhesive that keeps the layers together through hundreds of thousands of folds.
