Abstract

La présente invention concerne des modules d'affichage électroluminescents et à diode électroluminescente (DEL). Le module électroluminescent comprend une pluralité d'éléments électroluminescents connectés électriquement représentant des pixels et un dispositif de commande principal qui permet la sortie, à un module électroluminescent, d'une image dynamique et statique à partir d'une source d'un signal vidéo. L'invention concerne également au moins un tableau de distribution de signal et d'énergie, connecté au dispositif de commande principal et aux éléments électroluminescents mentionnés ci-dessus, qui fournit de l'énergie et émet des signaux de données. Les tableaux de distribution de signal et d'énergie, adoptés pour une émission séquentielle du signal de données avec une amplification du niveau et une correction des fronts d'impulsion, comportent des pilotes et des registres de stockage programmables. Ainsi, lesdits tableaux distribuent un signal de données à haute fréquence entre plusieurs éléments électroluminescents et changent un signal de rétroaction de taux par abaissement de la fréquence de la transmission de données, en fonction de la longueur d'un conducteur connectant les éléments électroluminescents. Ces derniers influencent, dans une plage temporelle entre les valeurs souhaitées, les paquets de données pour la synchronisation générale, par conséquent, l'émission de lumière alternée est fournie uniquement à l'élément électroluminescent requis, avec l'intensité souhaitée et à l'unité de temps prédéterminée. De manière facultative - également une couleur souhaitée. Le module comprend en outre au moins une unité de commutation, connectée au dispositif de commande principal et aux tableaux de distribution de signal et d'énergie, qui fournit l'énergie électrique et un signal de données du dispositif de commande principal aux tableaux de distribution de signal et d'énergie, ou à des groupes de tels tableaux.
