O-film Tech Co., Ltd Some updates from interviewing O-Film at C-Touch Taiwan 2017
They process sheet to sheet.
O-Film never stopped production but volume is shrinking.
They focus only on big volume and mobile is still big volume.
The roll speed is probably lower than photolith. Curing slows down the process as well.
They can an do 50inh max but no bigger. Most of the market is 20 to 30inch.
They sell transparent antenna film for Samsung smart watch interesting niche market but volume are too small.
O-Film is considering ultra low sheet resistance. Their record is 0.3ohm/sqm at 85% transmission. This opens up applications in heating.
