We use a soft lithography technique to pattern a high conductive poly(3,4-ethylene dioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) acting as anode in organic light emitting diodes. In this method all the polymer layers except for the desired pattern are lifted up from the substrate surface. We are able to define the emissive zones of our devices on a large area in a cheap and fast way. By comparing the devices realized using the patterned polymeric anode with an untreated indium, tin oxide substrate, we obtained current efficiency values that have the same order of magnitude: this is the first step for the realization of low cost devices suitable for flexible substrates.

Abstract

We use a soft lithography technique to pattern a high conductive poly(3,4-ethylene dioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) acting as anode in organic light emitting diodes. In this method all the polymer layers except for the desired pattern are lifted up from the substrate surface. We are able to define the emissive zones of our devices on a large area in a cheap and fast way. By comparing the devices realized using the patterned polymeric anode with an untreated indium, tin oxide substrate, we obtained current efficiency values that have the same order of magnitude: this is the first step for the realization of low cost devices suitable for flexible substrates.
