Abstract

L'invention concerne un affichage électrochromique à matrice passive à restitution d'image et définition améliorées, ainsi qu'un procédé de commande correspondant. On améliore la définition en appliquant aux contre-électrodes des pixels qui ne doivent pas être colorés une contre-tension qui supprime le flux de courant non désiré dans ces pixels.
