Multilayer ITO-Ag-ITO (IMI) stacks on polymer substrates were evaluated as transparent conductors for flexible organic light-emitting diode (OLED) displays. The IMI samples exhibited significantly reduced sheet resistance over ITO and slightly improved optical transmission. In addition, the IMI structures showed dramatically improved mechanical properties when subjected to bending both as a function of radius of curvature as well as number of cycles to a fixed radius. Organic light emitting devices fabricated on IMI anodes showed improved performance compared with those made on ITO anodes at current densities greater than 1 mA/cm2 due to the improved conductivity of the anode.
