%X 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 w/o for 200 nm thick films), and present high chemical stability.
