Abstract :
We developed a multi-color microfluidic organic light emitting device, which consists of liquid organic light emitting diodes (OLEDs) and electrochemiluminescence (ECL) devices. A 3 × 3 matrix of emitting pixels was fabricated in SU-8 microchannels sandwiched between polyethylene naphthalate (PEN) and glass substrates with indium tin oxide (ITO) anode and cathode pairs. Liquid organic semiconductor and ECL solutions as liquid emitters were injected into the microchannels. The electroluminescence (EL) and ECL were successfully obtained at the emitting pixels in the microchannels. The proposed structure can be applicable for multi-color liquid-based display.
