Abstract

L'invention concerne un module d'affichage et un terminal. Le module d'affichage comprend un écran flexible (1), un premier élément de fixation (2) et un second élément de fixation (3). Une première partie de l'écran flexible (1) est disposée à demeure au niveau du premier élément de fixation (2), et une seconde partie de l'écran flexible (1) est disposée à demeure au niveau du second élément de fixation (3). Une fente d'insertion (5) est ménagée au niveau du premier élément de fixation (2), et une glissière (4) est disposée au niveau du second élément de fixation (3). Un élément de support (8) est disposé coulissant dans la glissière (4), et peut se déplacer entre une première position et une seconde position. Dans la première position, l'élément de support (8) est situé dans la glissière (4), et dans la seconde position, l'élément de support (8) est partiellement situé dans la glissière (4) et partiellement situé dans la fente d'insertion (5). La conception du module d'affichage ne nécessite pas d'arbre rotatif, permettant ainsi à un écran pliant d'être ouvert ou fermé de manière simple et pratique, réalisant un fonctionnement flexible et réduisant les coûts.
