Abstract
(EN)
Disclosed are a backlight module (10) and a display device (1) having same. The backlight module (10) comprises: a surface light source (110) having a light emitting surface (114); a fluorescent film (120) covering the light emitting surface (114) of the surface light source (110); a support layer (130) disposed on the fluorescent film (120) and being a transparent adhesive film layer (132); and a diffusion sheet (140) covering the support layer (130). The backlight module (10) and the display device (1) having same reduces the number of layers of the diffusion sheet (140) in the backlight module (10) while guaranteeing high lighting effect is guarantee, thereby increasing the light transmittance, realizing evenly mixed light with better light mixing effect and efficient light emitting effect, and achieving the purpose of thinning the backlight module (10).

L'invention concerne un module de rétroéclairage (10) et un dispositif d'affichage (1) le comprenant. Le module de rétroéclairage (10) comprend : une source de lumière de surface (110) ayant une surface d'émission de lumière (114); un film fluorescent (120) recouvrant la surface d'émission de lumière (114) de la source de lumière de surface (110); une couche de support (130) disposée sur le film fluorescent (120) et étant une couche de film adhésif transparent (132); et une feuille de diffusion (140) recouvrant la couche de support (130). Le module de rétroéclairage (10) et le dispositif d'affichage (1) le comprenant réduisent le nombre de couches de la feuille de diffusion (140) dans le module de rétroéclairage (10) tout en garantissant qu'un effet d'éclairage élevé soit garanti, ce qui permet d'augmenter la transmittance de lumière, de réaliser une lumière uniformément mélangée ayant un meilleur effet de mélange de la lumière et un effet d'émission de lumière efficace, et d'atteindre le but d'éclaircir le module de rétroéclairage (10).
