Abstract
Apparatus for transferring organic material from a donor web onto a substrate to form a layer of organic material on one or more OLED devices including a web of donor material; first and second fixtures and a structure for applying fluid to a chamber to containing the fixtures to apply pressure to the non-transfer surface of the donor web so as to ensure the position of the donor web relative to the substrate; the first fixture including a transparent portion located in relationship to the non-transfer surface of the donor web to permit transmission of radiation through such transparent portion to the non-transfer surface of the donor web so that heat will be produced and the organic material will transfer from the donor web to the substrate.
