Abstract

Apparatus for permitting the transfer of organic material from a donor onto a substrate to form a layer of organic material on one or more OLED devices, comprising a first fixture arranged to support the donor and substrate in a relationship relative to one another whereby there will be either a separation between portions of the substrate and the donor, or the substrate and donor will be in contact, and wherein organic material will be transferred onto portions of the substrate; a second fixture aligned with and engaging the first fixture to clamp the donor and substrate and forming a chamber relative to a non-transfer surface of the donor; means for supplying a fluid to the chamber to apply pressure to the non-transfer surface of the donor so as to ensure the position of the donor relative to the substrate; and the first fixture including a transparent portion located in relationship to the non-transfer surface of the donor to permit transmission of radiation through such transparent portion to the non-transfer surface of the donor so that heat will be produced and the organic material will transfer from the donor to the substrate.
