Apparatus for permitting transfer of organic material from a donor to form a layer in an OLED device

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) the donor including radiation-absorbing material capable of absorbing radiation in a predetermined portion of the spectrum for producing heat which will cause the transfer of organic material;
• b) 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;
• c) 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;
• d) means for providing an airtight seal around the perimeter of the chamber;
• e) 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
• f) 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 and the non-transfer surface of the donor to the radiation-absorbing material so that heat will be produced in such material and the organic material will transfer from the donor to the substrate.
