Abstract
(EN)
A backlight module (100) and a display device are provided. The display device comprises the backlight module (100) and a display panel (101). The backlight module (100) comprises a shell body (110), a light guide plate (130, 230) and light sources (120, 320). The light guide plate (130, 230) is arranged in the shell body (110) and comprises a light exit surface (131, 231) and locating and protruding parts (133, 233). The locating and protruding parts (133, 233) protrude from the light exit surface (131, 231). The light sources (120, 320) are arranged on at least one side of the light guide plate (130, 230). The locating and protruding parts (133, 233) are used to simplify the assembling structure and assembling process of the display device.

L’invention concerne un module de rétroéclairage (100) et un dispositif d'affichage. Le dispositif d'affichage comprend le module de rétro-éclairage (100) et un panneau d'affichage (101). Le module de rétroéclairage (100) comprend un corps en coque (110), une plaque de guidage de lumière (130, 230) et des sources lumineuses (120, 320). La plaque de guidage de lumière (130, 230) est disposée dans le corps en coque (110) et comprend une surface de sortie de lumière (131, 231) et des pièces saillantes de positionnement (133, 233). Les pièces saillantes de positionnement (133, 233) prolongent en saillie la surface de sortie de lumière (131, 231). Les sources lumineuses (120, 320) sont disposées sur au moins un côté de la plaque de guidage de lumière (130, 230). Les pièces saillantes de positionnement (133, 233) sont utilisées pour simplifier la structure d'assemblage et l'assemblage du dispositif d'affichage.
