Abstract

La présente invention concerne un dispositif d'affichage électrophorétique multicolore qui comprend : un premier substrat pour fournir une surface d'affichage, et un second substrat qui fait face au premier substrat ; une pluralité de cavités qui sont formées entre les premier et second substrats ; un fluide de couleur destiné à être chargé dans une cavité, qui comprend des sous-pixels couleurs, parmi la pluralité de cavités ; des particules électrophorétiques blanches, qui sont dispersées dans le fluide de couleur, et des particules électrophorétiques noires, qui possèdent une mobilité électrophorétique différente par rapport aux particules électrophorétiques blanches ; et une pluralité d'électrodes pour régler la luminosité du fluide de couleur en réglant, à l'intérieur de la cavité, la proportion relative des particules électrophorétiques blanches et des particules électrophorétiques noires qui sont vues à travers la surface d'affichage, le fluide de couleur pouvant être coloré en utilisant juste un colorant.
