Seven-segment displays are used to show numerical quantities in electronic equipment, being present in most of the low-end electronics. In this work we describe a novel organic light emitting display made with poly(1,10 decanedioxy 2 methoxy - 1,2 phenylene - 1,2 ethenylene - 3,6 dimethoxy - 1,4 phenylene - 1,2 ethenylene 3 methoxy - 1,4 - phenylene) (OPPVDBC), tris(8-hydroxyquinoline)aluminum salt (Alq3) and a hole injection layer (PEDOT:PSS: poly(3,4 - ethylenedioxythiophene) : poly(styrenesulfonate)). The general device structure is FTO/PEDOT:PSS/OPPVDBC/Ca/Al or FTO/PEDOT:PSS/OPPVDBC/Alq3/Ca/Al. The FTO (fluorine-doped tin oxide) thin films are transparent (transmittance > 80 % in the visible region of the spectrum), conductive (< 15 omega/º for 200 nm thick films), and present high chemical stability.
