Dainippon Screen MFG Co Ltd developed an integrated manufacturing system to produce large OLED panels through coating processes.
Dainippon Screen and E.I. du Pont de Nemours & Co (DuPont) jointly established a new OLED manufacturing process based on the “multi-nozzle printing method,” which uses DuPont’s soluble low-molecular-weight organic EL material. And the companies employed this process for the new manufacturing system.
The system is applicable to the sizes of the fourth generation and later substrates. It is equipped with functions to feed and clean substrate, form a multilayer film with a linear coater, selectively coat portions of a substrate by nozzle-printing to form a light emitting layer and dry the resultant substrate.
