Abstract

We propose a first prototype of the microfluidic organic light emitting diode (OLED). A matrix of 3x3 OLED array was fabricated in the SU-8 microchannels sandwiched by the indium tin oxide (ITO) anode and cathode. The liquid organic semiconductors were employed for the light emitters and were injected into the microchannels. The electroluminescence was obtained in the microchannels under the optimized applied voltage. The current density of 2.11 mA/cm ² was measured at 60 V. Since flesh liquid organic semiconductors are continuously supplied to the emitting layer, long-term stable electroluminescence is expected by the proposed OLED.
