Abstract

L'invention porte sur un dispositif de commande, sur un module de panneau d'affichage, sur un dispositif d'affichage et sur un procédé de fabrication du dispositif de commande, permettant de réduire le nombre d'éléments du circuit de commande sans réduire le nombre de panneaux d'affichage à enlever, et sans augmenter les régions d'interconnexion sur un film. Spécifiquement, l'invention porte sur un dispositif de commande muni d'un film (1), sur lequel sont montés des interconnexions (4) et un élément de circuit (2), et commandant un panneau d'affichage. Le dispositif de commande est muni d'une première partie de film (1a) et d'une seconde partie de film (1b) dans le film (1), séparées l'une de l'autre par une incision (9) ménagée dans celles-ci, et chacune des première et seconde parties de film (1a et 1b) étant reliée au panneau d'affichage tout en étant pliées au moins une fois.
