Different foldable modules were fabricated and foldable polarizer's performance was evaluated. During RA test, chemical reactions occurred between I3-/I5- ions from polarizer and NH4+ ions from touch panel on encapsulation (TOE), resulting in discoloration of the foldable polarizer. To enhance foldable polarizer's reliability, NH3: SiH4 gas flow rate was adjusted.
