Abstract:
(EN) A light-emitting unit and a method for adjusting a light emitting spectrum thereof, a backlight module, and a liquid crystal display device. The light-emitting unit comprises a light source (1130) and a color filter layer (120) located at a light exit side of the light source (1130). The color filter layer (120) comprises at least two colors of color filters (121) arranged in an array, and the color filter layer (120) is configured to have different transmittances for at least two colors in white light emitted by the light source (1130). The adjustment on a spectrum of the light-emitting unit can improve the color gamut of a display device comprising the light-emitting unit.
(FR) L'invention concerne une unité électroluminescente et un procédé de réglage de son spectre d'émission de lumière, un module de rétroéclairage et un dispositif d'affichage à cristaux liquides. L'unité électroluminescente comprend une source de lumière (1130) et une couche de filtre coloré (120) située sur un côté de sortie de lumière de la source de lumière (1130). La couche de filtre coloré (120) comprend au moins deux couleurs de filtres colorés (121) agencés selon un réseau, et la couche de filtre coloré (120) est configurée pour avoir différentes transmittances pour au moins deux couleurs dans la lumière blanche émise par la source de lumière (1130). Le réglage sur un spectre de l'unité électroluminescente peut améliorer la gamme de couleurs d'un dispositif d'affichage comprenant l'unité électroluminescente.
(ZH) 一种发光装置及其发光光谱的调节方法、背光模组以及液晶显示装置。该发光装置包括光源(1130)以及位于光源(1130)出光侧的滤色层(120)。滤色层(120)包括阵列排布的至少两种颜色的滤色片(121),并且,滤色层(120)被配置为对光源(1130)发出的白光中的至少两种颜色的光的透过率不同。该发光装置通过对光谱的调节,可以提高包括该发光装置的显示装置的色域。
