Title
(EN) ROLLABLE DISPLAY DEVICE
(FR) DISPOSITIF D'AFFICHAGE ENROULABLE
(KO) 롤러블 디스플레이 장치
Abstract
(EN)
A rollable display device can prevent the inflow of foreign materials by minimizing exposure of the inside of a housing, the rollable display device comprising: a flexible display panel; a main roller for winding or unwinding the flexible display panel; a driving unit coupled to the flexible display panel so as to elevate the flexible display panel; a housing having the main roller mounted therein, and having an opening part formed to be long in a first direction on the upper part thereof so as to allow entrance and withdrawal of the flexible display panel; and an elastic part having one end coupled to the periphery of the opening part, and protruding to cover at least a portion of the opening part, wherein the elastic part comprises a rubber portion provided in a predetermined length in the first direction.
(FR)
La présente invention concerne un dispositif d'affichage enroulable qui peut empêcher l'entrée de matériaux étrangers en réduisant au minimum l'exposition de l'intérieur d'un boîtier, le dispositif d'affichage enroulable comprenant : un panneau d'affichage souple; un rouleau principal servant à enrouler ou à dérouler le panneau d'affichage souple; une unité d'entraînement couplée au panneau d'affichage souple de façon à élever le panneau d'affichage souple; un boîtier à l'intérieur duquel est monté le rouleau principal et qui possède une partie d'ouverture formée de façon à être longue dans une première direction sur la partie supérieure de celui-ci afin de permettre l'entrée et le retrait du panneau d'affichage souple; et une partie élastique ayant une extrémité couplée à la périphérie de la partie d'ouverture, et faisant saillie pour recouvrir au moins une partie de la partie d'ouverture, la partie élastique comprenant une partie en caoutchouc disposée dans une longueur prédéterminée dans la première direction.
