We demonstrate the patterning of top emitting organic light emitting diodes (OLEDs) by direct-write Aerosol Jet printing in air from non-halogenated solvents. Indane was determined to be a suitable single solvent to dissolve the archetypal host poly(N-vinylcarbazole) and guest emitting dopants complexes for red, green, and blue OLEDs, and to print on both PEDOT:PSS and MoO3 transport layers. The Aerosol Jet deposition parameters were studied, including: atomization flow rate, exhaust flow rate, focusing sheath flow rate, nozzle-to-substrate distance, nozzle speed, and substrate temperature. A line width of 30 μm and thickness of 30 nm was achieved, resulting in RGB OLEDs fabricated side-by-side with a pixel density of 140 ppi.
