(FR) ECRAN VIDEO MULTICOUCHE AMELIORE
Abstract
(EN)
A display device comprising at least two display layers at least in part overlapping in which at least one of said display layers has a dissimilar configuration to the other display layer(s) such that moiré interference is reduced.
(FR)
L'invention concerne un dispositif de visualisation comprenant au moins deux couches de visualisation se chevauchant au moins en partie, où au moins une desdites couches de visualisation présente une configuration différente de celle de(s) l'autre(s) couche(s), de sorte à réduire les interférences par moiré.
