Abstract

L'invention concerne des modules d'affichage comprenant une couche de polarisation circulaire pour créer une correspondance de couleur entre une zone de visualisation d'un dispositif d'affichage électronique et une couche de masquage lorsque l'affichage électronique est mis hors tension. La couche de polarisation circulaire peut être disposée entre la couche de masquage et l'affichage électronique. La couche de polarisation circulaire peut comprendre un polariseur linéaire comprenant un axe de transmission décalé par rapport à l'axe de transmission d'un polariseur linéaire de l'affichage électronique par un angle de décalage.
