Abstract
(EN) The present invention relates to a display device. A display device comprises: a display panel; a substrate positioned at the rear of the display panel; a plurality of light sources mounted on the substrate and providing light to the display panel; a reflective sheet positioned on the substrate, and having a plurality of holes formed to correspond to the position of the plurality of light sources and a coupling hole formed between the plurality of holes; and a supporter fixed to the substrate, inserted into the coupling hole, and comprising a body fixed to the substrate and a guide extending and gradually tapering toward the display panel from the upper side of the body, wherein the body of the supporter has a cylindrical shape corresponding to the coupling hole, and the guide of the supporter can include a guide tilt surface connected from the side surface of the body.
(FR) La présente invention concerne un dispositif d'affichage. Un dispositif d'affichage comprend : un panneau d'affichage ; un substrat positionné à l'arrière du panneau d'affichage ; une pluralité de sources de lumière montées sur le substrat et fournissant de la lumière au panneau d'affichage ; une feuille réfléchissante positionnée sur le substrat, et ayant une pluralité de trous formés de sorte à correspondre à la position de la pluralité de sources de lumière et un trou d'accouplement formé entre la pluralité de trous ; et un support fixé au substrat, inséré dans le trou d'accouplement, et comprenant un corps fixé au substrat et un guide s'étendant et se rétrécissant progressivement vers le panneau d'affichage à partir du côté supérieur du corps, le corps du support ayant une forme cylindrique correspondant au trou d'accouplement, et le guide du support pouvant comprendre une surface de guidage inclinée reliée à partir de la surface latérale du corps.
(KO) 본 발명은 디스플레이 디바이스에 관한 것이다. 디스플레이 디바이스는 디스플레이 패널; 상기 디스플레이 패널의 후방에 위치하는 기판; 상기 기판 상에 실장되고, 상기 디스플레이 패널에 빛을 제공하는 복수개의 광원; 상기 기판 상에 위치하고, 상기 복수개의 광원의 위치에 대응하여 형성된 복수개의 홀들과 상기 복수개의 홀들 사이에 형성되는 결합홀을 구비하는 반사시트; 그리고, 상기 기판에 고정되며, 상기 결합홀에 삽입되는 서포터로서, 상기 기판에 고정되는 바디; 그리고, 상기 바디의 상측에서 상기 디스플레이 패널을 향해 점차 가늘어지며 연장되는 가이드를 포함하는 서포터를 포함하고, 상기 서포터의 바디는, 상기 결합홀에 대응되는 실린더 형상이고, 상기 서포터의 가이드는, 상기 바디의 측면으로부터 이어지는 가이드 경사면을 포함할 수 있다.
