After many years of promising a flexible display-enabled phone, Samsung has finally released the trial version of the Fold. However, with its Infinity Flex diplay an OLED on a "composite polymer" substrate with a likely oxide TFT, early reviews of the Fold have demonstrated a lot of early display failures, well short of the promised 100,000 folds. While it may last slightly longer in wide-spread release, the underlying durability concerns will remain and be limiting for a device that will cost approximately $2,000. Organic TFTs will likely need to be used in order to get to longer lifetime devices as oxides will always inherently be susceptible to breaking and their deposition temperatures will limit the compatible substrate options.
