Samsung still uses FMM to fabricate Super AMOLED HD displays
There's an interesting article discussing a team of engineers in Samsung which developed the Super AMOLED HD displays. As was suggested before, Samsung is still using a Shadow Mask (or FMM) to fabricate Super AMOLED HD displays. Using new materials and a new manufacturing process they managed to develop such a fine mask that enabled over 300ppi - a thing that was considered impossible by several companies.
So Samsung didn't move to LITI production yet, and they are still using FMM. Samsung also developed a new technique called Small Mask Scanning (or SMS) will enables them to scale up AMOLED production to 8-Gen plants.
