P‐72: Nozzle Jet Printing of Organic Thin Films for Solution Process of Organic Light Emitting Diodes

Abstract

We fabricated an organic light emitting diode using poly(9vinylcarbazole) : tris[2-(p-tolyl)pyridine]iridium(III) emitting layer fabricated by nozzle jet printing. Uniform thin films were formed onto both of glass and PEN substrate. Bending test of the flexible OLEDs was also demonstrated and its performance was stably maintained until 300 cycles of bending.
