A backlight module, comprising a back plate (10) having an opening on the top surface, a first reflective sheet (20a) provided on the bottom surface of the back plate (10), a plurality of light guide plates (30) arranged on the first reflective sheet (20a) at intervals, backlight source assemblies (40), and an optical film set (50) provided at the opening on the top surface of the back plate (10). Each backlight source assembly (40) comprises a wedge-shaped radiator (41) and light sources (42) fixed on the two adjacent slopes of the radiator (41); the backlight source assembly (40) is provided in a gap (G) between two adjacent light guide plates (30). The backlight module facilitates narrow-bezel and ultrathin design, reduces manufacturing costs, has good backlight consistency, thereby decreasing the light mixing distance, and can also effectively eliminate the defects of bright and dark bands appearing on the four sides of a conventional backlight module. |
