Abstract

Ce dispositif d'affichage électro-optique comporte plusieurs modules (M1-M4) pourvus, chacun, d'un projecteur (5) recevant des signaux électriques, les convertissant en images optiques et projetant ces images sur un écran (4) par le biais d'un appareil de projection (18). Les modules (M1-M4) sont disposés côte à côte de manière à donner lieu à un affichage combiné sur l'écran. Un système de calibration détecte les distorsions survenant dans l'affichage combiné et dues au système de projection de chaque module et modifie les signaux électriques envoyés au projecteur de chaque module afin de les corriger.
