Abstract

L'invention concerne un module de circuit assemblé d'un grand écran LCD. Le module de circuit comprend au moins une borne d'entrée de signal et S blocs. Les S blocs sont divisés en N blocs transversaux et M blocs longitudinaux. Chacun des blocs comprend un module principal de mise à l'échelle de commande avec une fonction de mise à l'échelle. Le signal est appliqué au module principal de mise à l'échelle de commande d'un premier bloc. Ensuite, le signal est transféré à un deuxième bloc dans la direction transversale, au dernier bloc dans la direction transversale, à un deuxième bloc dans la direction longitudinale et au dernier bloc dans l'ordre à partir du module principal de mise à l'échelle de commande du premier bloc.
