Abstract

Un procédé de fabrication d'un réseau lenticulaire comprend : la fourniture d'un substrat (101); et la formation d'au moins une structure de blocage de la lumière (103) et d'au moins deux lentilles (102) sur le substrat (101), et leur configuration de telle sorte que la structure de blocage de la lumière (103) correspond à une région limite entre lentilles adjacentes parmi les deux lentilles ou plus (102). La structure de blocage de la lumière (103) peut réduire ou éliminer efficacement la lumière parasite générée au niveau d'une région limite entre deux lentilles (102), ce qui permet d'améliorer efficacement la qualité d'une image projetée par l'intermédiaire de la région limite.
