Abstract

La présente invention concerne une structure de support (10) et un dispositif d'affichage flexible (100). La structure de support (10) comprend un ensemble arbre rotatif (12), une plaque de support (14) et un ensemble de transmission (16), et l'ensemble de transmission (16) est en prise mobile avec l'ensemble arbre rotatif (12) et avec la plaque de support (14). La structure de support (10) peut être commutée entre un état déplié et un état plié. Pendant la commutation de l'état déplié à l'état plié, l'ensemble de transmission (16) intervient dans la conversion de la rotation de la plaque de support (14) en un mouvement d'approche l'un de l'autre de l'ensemble arbre rotatif (12) et de la plaque de support (14) ; lors de la commutation de l'état plié à l'état déplié, l'ensemble de transmission (16) intervient dans la conversion de rotation de la plaque de support (14) en un mouvement d'éloignement l'un de l'autre de l'ensemble arbre rotatif (12) et de la plaque de support (14).
