Abstract

L'invention concerne un papier électronique à cristaux liquides cholestériques couleur. Le papier électronique comprend trois cellules à cristaux liquides formées par le chevauchement vertical de quatre couches de substrats (1, 1', 1'', 2, 2', 2'', 3, 3', 3'', 4, 4', 4''). Des couches de cristaux liquides cholestériques (19, 19', 19'', 20, 20', 20'', 21, 21', 21'') capables de réfléchir la lumière rouge, verte et bleue sont respectivement contenues dans les trois cellules à cristaux liquides. Le papier électronique comprend en outre une couche faisant écran à la lumière (5, 5', 5'') et peut faire écran contre la fuite de lumière d'une zone de non-affichage afin d'empêcher les influences négatives sur le rapport de contraste et la luminosité de la zone d'affichage dues à la fuite de lumière de la zone de non-affichage. Le papier électronique comprend en outre des électrodes de substrat (13, 13', 13'', 14, 14', 14'', 15, 15', 15'', 16, 16', 16'', 17, 17', 17'', 18, 18', 18'') qui sont formées dans un mode composé d'une électrode métallique (b, b', b'') et d'une électrode transparente (a, a', a'') et qui peuvent réduire la résistance du fil de sortie. Le papier électronique comprend en outre une couche d'absorption de lumière (6, 6', 6'') qui est intégrée et qui peut garantir l'absorption complète, par la couche d'absorption de lumière (6, 6', 6''), de la lumière incidente passant à travers les électrodes de substrat. Sur la base d'une économie de coût et d'une réduction de l'épaisseur, le papier électronique à cristaux liquides cholestériques couleur peut permettre d'obtenir un rapport de contraste élevé et un affichage à luminosité élevée en accroissant la transmissivité et en diminuant la réflectivité, il peut empêcher l'effet d'affichage médiocre provoqué par la force externe mécanique, et offre un support de structure pour permettre la fabrication en grand format et améliorer la performance de l'affichage.
