Abstract: front page image
(EN)Disclosed is a backlight device. The backlight device comprises: a light source; a light guide panel which uniformly guides the light emitted from the light source; a first reflection member which is installed in the lower part of the light guide panel; and a diffusion member which is installed in the upper part of the light guide panel, wherein the light guide panel is divided into a plurality of sections by at least one inclined surface, and for the one inclined surface, a second reflection member for reflecting the light emitted from the light source toward the inside of the light guide panel is installed on a first inclined surface, and at least one light source is positioned in the lower part of the light guide panel equipped with the second reflection member whereby the light is emitted from each section of the light guide panel.
(FR)L'invention concerne un dispositif rétroéclairé qui comprend: une source lumineuse; un panneau guide de lumière qui guide uniformément la lumière émise par la source lumineuse; un premier élément réfléchissant qui est installé dans la partie inférieure du panneau guide de lumière; et un élément de diffusion qui est installé dans la partie supérieure du panneau guide de lumière. Le panneau guide de lumière est divisé en une pluralité de parties par au moins une surface inclinée, et, pour cette surface inclinée, un second élément réfléchissant servant à réfléchir la lumière émise par la source lumineuse vers l'intérieur du panneau guide de lumière est installé sur une première surface inclinée, et au moins une source lumineuse est positionnée dans la partie inférieure du panneau guide de lumière équipé du second élément réfléchissant, la lumière étant émise par chaque partie du panneau guide de lumière.
(KO)백라이트 장치가 개시된다. 상기 백라이트 장치는 광원과, 광원에서 나온 빛을 균일하게 도광시키는 도광판과, 도광판의 하부에 설치되는 제1 반사재와, 도광판의 상부에 설치되는 확산재를 포함하는 백라이트 장치에 있어서, 도광판은 적어도 하나 이상의 경사면에 의해 다수의 구획으로 구분되며, 적어도 하나 이상의 경사면 중 제1 경사면에는 광원에서 나오는 빛을 도광판 내부로 반사사키기 위한 제2 반사재가 설치되고, 제2 반사재가 설치된 도광판 하부에 적어도 하나 이상의 광원이 설치됨으로써, 도광판을 구획별로 발광하는 것을 특징으로 한다.
