Omdia says that the main challenge of the foldable OLED market is the reliability of the displays - mainly the cover, the touch sensor and the polarizer films. Display makers will need to adopt new technologies such as ultrathin glass covers (UTG), touch sensors on TFE and color filters on TFE

DSCC recently announced its own forecasts for the foldable OLED market, which are pretty similar to Omdia's.
