Abstract

La présente invention concerne un système d'impression de terminal latéral de panneau d'affichage et, de manière plus spécifique lors de la formation d'un terminal sur le côté d'un panneau d'affichage mince, la possibilité de former rapidement et avec précision un terminal latéral par application d'un procédé d'impression PAD. En particulier, la présente invention permet de former facilement un motif de bande tridimensionnel dont la forme s'étend, sur la base du côté d'un bord d'un panneau d'affichage, du côté jusqu'à la partie supérieure (ou avant) et jusqu'à la partie inférieure (ou arrière) (une section transversale en forme de C rectangulaire). Par conséquent, la présente invention garantit un degré de liberté considérable dans des procédés de conception et de fabrication lors de la fabrication de panneaux d'affichage à grande surface, mais également de divers types de panneaux d'affichage. Ainsi, la fiabilité et la compétitivité peuvent être améliorées dans le domaine des panneaux d'affichage, dans le domaine de la fabrication de panneaux d'affichage et dans le domaine des appareils et systèmes utilisés dans la fabrication de panneaux d'affichage, ainsi que dans des domaines similaires ou apparentés à ceux-ci.
