Method and apparatus for depositing LED organic film

An apparatus for depositing one or more organic materials onto a substrate, comprising:

• a source to receive a quantity of organic particles containing solvent, the source configured to remove solvent from the quantity of organic particles to provide a quantity of substantially solvent-free organic particles;
• a discharge nozzle having a plurality of openings to receive the quantity of substantially solvent-free organic particles and to discharge the quantity of substantially solvent-free organic particles from the discharge nozzle onto the substrate;
• a thermal source associated with the discharge nozzle, the thermal source configured to receive the quantity of substantially solvent-free organic particles from the source and to deliver at least a portion of the quantity of substantially solvent-free organic particles to the discharge nozzle;
• and
• a housing to integrate the source and the discharge nozzle, the housing defining a flow path between the source and the discharge nozzle.
