Abstract
The present invention provides a backlight module, which includes: a backplane (2), a light guide plate (4) arranged in the backplane (2), a backlight source (6) arranged in the backplane (2) and located at one side of the light guide plate (4), a quantum dot rail (8) arranged between the backlight source (6) and the light guide plate (4), and a retention rack (10) that retains the quantum dot rail (8). The retention rack (10) is fixedly mounted to the backplane (2). The retention rack (10) includes a trough section (102) formed therein to correspond to the quantum dot rail (8). One side of the quantum dot rail (8) is mounted in the trough section (102) through adhesion. The backlight module according to the present invention includes a retention rack arranged therein to fixedly mount the quantum dot rail between the backlight source and the light guide plate of the backlight module so as to effectively enhance color saturation of the backlight module. The retention member has a simple structure and a low cost and can effectively protect the quantum dot rail to prevent undesired rotation and damage of the quantum dot rail caused by external forces.
