摘要： The present teachings provide methods for depositing and patterning organic light-emitting device (OLED) buffer layers. The method can use a thermal printing process and one or more additional processes, such as vacuum thermal evaporation (VTE), to create an OLED stack. OLED stack structures are also provided wherein which at least one of the charge injection or charge transport layers is formed by a thermal printing method at a high deposition rate. The organic layer can be subject to post-deposition treatment such as baking. The structure of the organic layer can be amorphous, crystalline, porous, dense, smooth, rough, or a combination thereof, depending on deposition parameters and post-treatment conditions. The organic layer can improve light out-coupling efficiency of an OLED, increase conductivity, decrease index of refraction, and/or modify the emission chromaticity of an OLED.

摘要： The disclosure relates to providing printed structures of polymer that have substantially flat printed surfaces. In one embodiment, the disclosure relates to a post-printing treatment apparatus for receiving a substrate supporting a polymer printing thereon. The polymer can be PMMA or other suitable polymer. In a related embodiment, the polymer defines a thermoplastic polymer having a glass transition temperature. The apparatus can comprise of a chamber, and input manifold, an exhaust manifold, a solvent reservoir and a gas reservoir. The solvent reservoir provides one or more solvent systems adapted to chemically bind, and potentially react, with the polymer. The gas reservoir provides one or more gases for drying the substrate and printed polymer after the solvent treatment step. In one application, a substrate having printed surface thereon is placed in the chamber and exposed to the solvent system for sufficient period of time to provide substantially flat print surfaces.
