Abstract

We propose ribbon type flexible organic light emitting diodes (OLEDs), which can be integrated into textiles, using liquid organic semiconductors (LOSs). A linear flexible microchannel, which consists of a liquid light-emitting layer with LOS sandwiched between two indium tin oxide (ITO) electrodes, was fabricated with photolithography and heterogeneous bonding. LOSs were injected into the SU-8-based linear microchannels of 70 mm in length. Three different colors of photoluminescence (PL) emission were observed from flexible linear microchannels. Liner electroluminescence (EL) emission was successfully obtained in a bending state as well as straight state. We expect that the proposed microfluidic OLED ribbons will have high potential for future free-formable wearable devices such as electronic textiles.
