Abrégé
(EN)
The present invention relates to a display device including a sub-backlight, which can prevent the obscure sights caused by light from the light source of the sub-backlight arriving on the object or reel of the main display screen and then reflecting in the frontal direction. The sub-backlight (40) of the present invention includes a second light guide panel (41) having an opening part (42) formed therein corresponding to a transparent window (16), a second light source (43) disposed around the second light guide panel (41), and a polymer dispersed liquid crystal (PDLC) sheet (44) disposed close to the front side of the opening part (42) of the second light guide panel (41).

La présente invention a trait à un écran incluant un rétroéclairage secondaire, lequel écran permet d'empêcher que les vues obscures causées par la lumière provenant de la source lumineuse du rétroéclairage secondaire n'arrivent sur l'objet ou la bobine de l'écran principal puis ne se réfléchissent dans la direction allant vers l'avant. Le rétroéclairage secondaire (40) selon la présente invention inclut un second panneau de guide d'ondes optique (41) qui est doté d'une partie d'ouverture (42) correspondant à une fenêtre transparente (16), une seconde source lumineuse (43) qui est disposée autour du second panneau de guide d'ondes optique (41), et une feuille de cristaux liquides à dispersion de polymère (PDLC) (44) qui est disposée à proximité du côté avant de la partie d'ouverture (42) du second panneau de guide d'ondes optique (41).

본 발명은 서브백라이트를 구비한 디스플레이장치에 관한 것으로서, 서브백라이트의 광원이 직접 메인디스플레이화면의 릴 또는 물체에 도달하여 전방으로 반사됨으로 인해 발생되는 불명료한 시야를 방지할 수 있는 디스플레이장치이다. 본 발명의 서브백라이트유닛(40)은 투시창(16)에 대응하도록 개구부(42)가 형성된 제2도광판(41)과, 상기 도광판(41)의 둘레부에 배치되는 제2광원(43)과, 상기 제2도광판(41)의 개구부(42)의 전방에 근접배치되는 PDLC(Polymer Dispersed Liquid Crystal)시트(44)를 포함한다.
