No, they cannot. As I posted above, OLEDS are coated by a different process.
Some digital materials can be coated by film or paper coaters.
Film coaters are designed to coat water based materials. They cannot coat using organic solvents. This simple problem causes all kinds of problems when trying to convert over from one to the other.
Organic solvent based materials take considerably different methodology than water based materials, which includes proper removal of solvent by scrubbing the air. Some cannot even be coated, they must be cast.
