THIS IS LIKELY THE IPHONE FOLD DISPLAY, AND IT LOOKS AMAZING

Summary from the TLDR Design newsletter

Samsung has unveiled a prototype folding display with an almost completely invisible crease, widely believed to be the panel Apple has been waiting for to use in the iPhone Fold after years of rejecting visibly creased screens. Shown briefly at CES and quickly removed, the display appears far more advanced than current Galaxy Fold panels and matches the rumored iPhone Fold aspect ratio, suggesting that Samsung has finally met Apple's stringent requirements for a creaseless folding screen.
