Title
(EN) BACKLIGHT MODULE AND LIQUID CRYSTAL DISPLAY
(FR) MODULE DE RÉTROÉCLAIRAGE ET DISPOSITIF D'AFFICHAGE À CRISTAUX LIQUIDES

Abstract
(EN)
A backlight module. A reflection surface (221) and a light emergence surface (222) of a light guide plate (22) include two bottom surfaces therebetween, and the two bottom surfaces comprise one support bottom surface (224). The backlight module also includes support columns (24). The support bottom surface (224) is provided with inclined contact surfaces (227). The support columns (24) are attached to the inclined contact surfaces (227). The direction of gravity is parallel to the light source length direction, so when the light guide plate (22) moves along the gravity direction thereof, the action of a force is generated between same and the support columns (24). Also disclosed is a liquid crystal display having a backlight module.

La présente invention porte sur un module de rétroéclairage. Une surface de réflexion (221) et une surface émergente de lumière (222) d'une plaque de guidage de lumière (22) comprennent deux surfaces inférieures entre celles-ci, et les deux surfaces inférieures comprennent une surface inférieure de support (224). Le module de rétroéclairage comprend également une colonne de support (24). Une surface inférieure de support (224) comporte un plan de contact incliné (222). La colonne de support (24) est attachée au plan de contact incliné (227). Une direction de gravité est parallèle à la direction de longueur de source lumineuse et lorsque la plaque de guidage de lumière (22) se déplace le long de la direction de gravité de celle-ci, l'action d'une force est générée entre celle-ci et la colonne de support (24). La présente invention porte également sur un dispositif d'affichage à cristaux liquides ayant un module de rétroéclairage.
