For anyone wanting to make a transparent OLED, you can just peel the backing foil off a regular OLED. Beware that without the foil, the OLED is super fragile - the back touching anything will make rows/columns break, so if I were you I'd replace it with a sheet of clear plastic/glass for actual use.
