Abstract: front page image
(EN)The present invention relates to a display device and a backlight unit thereof, and according to one embodiment of the present invention, the display device comprises: a frame; a plurality of light-emitting diodes systematically arranged on the frame; an optical unit arranged on the upper part of the plurality of light-emitting diodes, and including a display panel and a fluorescent sheet and/or an optical sheet; and a light guide plate arranged between the frame and the optical unit so as to cover the plurality of light-emitting diodes, wherein the light guide plate is positioned so as to correspond to the position in which the plurality of light-emitting diodes are arranged, and a light source groove, on which light emitted from the plurality of light-emitting diodes is incident, can be formed. According to the present invention, the display device can be usable as a direct-type backlight unit even without using a separate lens according to the formation of the light source groove at the position corresponding to a light-emitting diode package such that the light incident on a light guide plate included in a backlight unit is dispersed in a lateral direction.
(FR)La présente invention concerne un dispositif d'affichage et une unité de rétroéclairage associée, et selon un mode de réalisation de la présente invention, le dispositif d'affichage comprend : un cadre; une pluralité de diodes électroluminescentes disposées systématiquement sur le cadre; une unité optique agencée sur la partie supérieure de la pluralité de diodes électroluminescentes, et comprenant un panneau d'affichage et une feuille fluorescente et/ou une feuille optique; et une plaque guide de lumière disposée entre le cadre et l'unité optique de manière à recouvrir la pluralité de diodes électroluminescentes, la plaque guide de lumière étant positionnée de manière à correspondre à la position dans laquelle la pluralité de diodes électroluminescentes sont agencées, et une rainure de source de lumière, sur laquelle la lumière émise par la pluralité de diodes électroluminescentes est incidente, peut être formée. Selon la présente invention, le dispositif d'affichage peut être utilisable en tant qu'unité de rétroéclairage du type direct même sans utiliser de lentille séparée en fonction de la formation de la rainure de source de lumière à la position correspondant à un boîtier de diode électroluminescente de telle sorte que la lumière incidente sur une plaque guide de lumière incluse dans une unité de rétroéclairage est dispersée dans une direction latérale.
(KO)본 발명은 디스플레이 장치 및 그의 백라이트 유닛에 관한 것으로, 본 발명의 일 실시예에 따른 디스플레이 장치는, 프레임; 상기 프레임 상에 규칙적으로 배치된 복수의 발광 다이오드; 상기 복수의 발광 다이오드 상부에 배치되고, 형광시트 및 광학시트 중 어느 하나 이상과 디스플레이 패널을 포함하는 광학부; 및 상기 복수의 발광 다이오드를 덮도록 상기 프레임과 광학부 사이에 배치된 도광판을 포함하고, 상기 도광판은 상기 복수의 발광 다이오드가 배치된 위치에 대응되게 위치하며, 상기 복수의 발광 다이오드에서 방출된 광이 입사되는 광원홈이 형성될 수 있다. 본 발명에 의하면, 디스플레이 장치에 백라이트 유닛에 포함된 도광판으로 입사된 광이 측면 방향으로 분산되도록 발광 다이오드 패키지에 대응되는 위치에 광원홈이 형성됨에 따라 별도의 렌즈를 이용하지 않아도 직하형 백라이트 유닛으로 이용할 수 있다.
