Abstract

Procédé de fabrication d'un réseau lenticulaire, comprenant : la fourniture d'un substrat (100), le substrat (100) étant pourvu d'au moins deux lentilles (101) ; et la formation d'au moins une structure de protection contre la lumière (102) sur le substrat (100), de sorte que l'au moins une structure de protection contre la lumière (102) corresponde à une zone de jonction des lentilles adjacentes (101) dans les au moins deux lentilles (101). Selon le procédé, la lumière irradiée sur le réseau lenticulaire est protégée au moyen de l'au moins une structure de protection contre la lumière (102) formée sur le substrat (100) du réseau lenticulaire, de sorte que le problème dans le réseau lenticulaire d'une position de projection de lumière incorrecte d'un sous-pixel provoquée par une structure de section transversale irrégulière formée dans la zone de jonction entre les lentilles adjacentes (101) est résolu, et la diaphonie entre les images gauche et droite peut être réduite ou éliminée.
