Abstract: front page image
(EN)A backlight module and a display device including the same are provided. The backlight module (100,200,300) includes a backplate (110,210,310), at least one light source (120,220,320), a light guiding plate (130,230,330) and a heat-conducting support (140,240,340). The light guiding plate (130,230,330) includes a light emitting surface (131) and a bottom surface (132) opposite to the light emitting surface (131). The bottom surface (132) of the light guiding plate (130,230,330) is provided with a concave groove (133) in which the light sources (120,220,320) are provided. The heat-conducting support (140,240,340) is used to support the light guiding plate (130,230,330) and the light sources (120,220,320) and disperse heat from them. The backplate (110,210,310) is mounted with the light guiding plate (130,230,330), the light sources (120,220,320) and the heat-conducting support (140,240,340). The backlight module can improve the heat dispersing effect.
(FR)La présente invention concerne un module de rétroéclairage et un dispositif d'affichage l'utilisant. Le module de rétroéclairage (100,200,300) comprend une plaque arrière (110,210,310), au moins une source de lumière (120,220,320), une plaque de guidage de lumière (130,230,330) et un support conducteur de la chaleur (140,240,340). La plaque de guidage de lumière (130, 230,330) comprend une surface d'émission de lumière (131) et une surface inférieure (132) opposée à la surface d'émission de lumière (131). La surface inférieure (132) de la plaque de guidage de lumière (130, 230,330) est pourvue d'une rainure concave (133) dans laquelle sont logées les sources de lumière (120, 220,320). Le support conducteur de la chaleur (140, 240,340) est utilisé pour supporter la plaque de guidage de lumière (130, 230,330) et les sources de lumière (120, 220,320) et disperser la chaleur provenant de celles-ci. La plaque arrière (110, 210,310) est montée avec la plaque de guidage de lumière (130, 230,330), les sources de lumière (120, 220,320) et le support conducteur de la chaleur (140, 240,340). Le présent module de rétroéclairage peut ainsi améliorer l'effet de dissipation de la chaleur.
