The discovery of organic electroluminescence (EL) in manufacturable small molecule and π-conjugated polymer thin-film format has led to the commercialization of organic light-emitting diode (OLED) technology and the development of many other novel semiconductor devices. Flexible organic light emitting devices (OLEDs) have been fabricated on flexible substrates using conducting polymers prepared by vapor-phase polymerization method. In this paper, we report on the performance of OLEDs using films of highly conductive poly(3,4-ethylenedioxythiophene) : p-toluene sulfonate (PEDOT:PTS) anodes without an ITO. These conductive PEDOT:PTS films have a high transparency up to 80%, and possess a very low sheet resistance of 100 Ω/sq-1 at 100nm thickness and patterning is easily formed using a simple lithography or plasma etching method. ITO-free OLEDs with PEDOT:PTS anode have been demonstrated on both glass and plastic substrates with resultant performance comparable to equivalent ITO anode devices. |
