Abstract
Récepteur de communication de données (605) stockant un ensemble de données d'image et affichant des images associées sur un affichage à rangées divisées en premier et second segments. Le récepteur (605) comprend une base de données (635) de stockage d'un ensemble de fonctions orthonormées et des activeurs de rangées (650), couplés à la base de données (635), pour l'activation du premier segment de l'affichage par des premières tensions associées à un premier sous-ensemble de fonctions orthonormées et pour l'activation du second segment de l'affichage par des secondes tensions associées à une fonction restante incluse dans l'ensemble de fonctions orthonormées lors d'une première pluralité d'intervalles séquentiels de temps. Les activeurs de rangées (650) activent le premier segment par les secondes tensions associées à la fonction restante et activent le second segment par les premières tensions associées au premier sous-ensemble de fonctions orthonormées lors d'une seconde pluralité d'intervalles séquentiels de temps.
