In pixellated electronic devices such as polymer emissive displays (PEDs), good operating lifetime is achieved through the use of a high resistivity buffer layer of conductive organic polymer between the anode layer and the photoactive layer. The improved high resistivity conductive layer gives long lifetime with reduced or no cross-talk and current leakage between neighboring pixels.

La présente invention concerne des dispositifs électroniques pixélisés, tels que des systèmes d'affichage émissifs polymères (polymer emissive display : PED). L'objectif de cette invention est d'obtenir une bonne durée de vie d'exploitation. A cette fin, une couche tampon à haute résistivité, constituée de polymère organique conducteur, est utilisée entre la couche d'anode et la couche photoactive. La couche conductrice à haute résistivité améliorée assure une longue durée de vie et une réduction ou une suppression de l'intermodulation et des fuites de courant entre des pixels voisins.
