Abstract

La présente invention concerne une structure de charnière à repliement vers l'intérieur sur laquelle est monté un panneau d'affichage souple : une barre de haut-bas qui se déplace vers le haut et vers le bas est montée séparément sur une partie centrale pliable de la structure de charnière de telle sorte que le panneau d'affichage souple, dans un état complètement déplié, est monté non seulement sur une paire de panneaux gauche et droit mais également sur la barre de haut-bas ; et les axes de rotation d'une paire de supports rotatifs qui sont respectivement fixés aux panneaux gauche et droit et tournent sont montés à proximité l'un de l'autre, réduisant ainsi au minimum l'épaisseur d'un dispositif de communication mobile tel qu'un téléphone intelligent.
