Abstract

Systems and arrangements of OVJP deposition devices are provided, in which one or more organic material crucibles are directly attached to an injection block and a print head without the need for external delivery components such as feedtubes. Each crucible may be hermetically sealed until it is attached to the injection block, allowing for a single device to provide for storage, transport, and deposition of the organic material.
