    摘要: A method for transferring organic material from a flexible donor element onto a substrate to form a layer of organic material in making one or more OLED devices, includes providing the flexible donor element and the substrate in a spaced relationship within a chamber under atmospheric pressure defined by a transfer station so that the flexible donor element partitions the chamber into first and second cavities; varying the pressure differential between the first and second cavities to cause the flexible donor element to move into a contact relationship with the substrate; providing a transparent window which defines the top surface of the second cavity; and providing radiation energy through the transparent window onto the flexible donor element in contact with the substrate to cause the flexible donor element to absorb heat and transfer organic material onto the substrate.
