Abstract

La présente invention concerne une structure de fond de panier d'un écran d'affichage et un écran intelligent interactif. La structure de fond de panier de l'écran d'affichage comprend un fond de panier (10) et une coque arrière (20), le fond de panier (10) comprenant une première paroi (110), une paroi de liaison (120) et une seconde paroi (130), une extrémité de la paroi de liaison (120) étant reliée à la première paroi (110), et l'autre extrémité de la paroi de liaison (120) étant reliée à la deuxième paroi (130); la première paroi (110), la paroi de liaison (120) et la seconde paroi (130) forment une forme étagée, et le plan où la première paroi (110) est située est plus élevé par rapport au plan où la seconde paroi (130) est située ; et la coque arrière (20) est disposée sur un côté extérieur de la seconde paroi (130) de façon à la recouvrir, et la coque arrière (20) affleure la première paroi (110). La structure de fond de panier résout les problèmes techniques liés à la mauvaise intégration et à l'aspect de l'écran d'affichage qui sont provoqués par le fait que la coque arrière (20) fait saillie vers l'extérieur.
