ABSTRACT:
A light-emissive polymer device comprising: an anode; a cathode; a conjugated light-emissive polymer layer located between the anode and the cathode; and a driver for applying a voltage drive scheme between the anode and the cathode of a pattern having a relatively high voltage portion which causes the polymer layer to emit light and a relatively low voltage portion during which substantially no light is emitted by the polymer layer.
