Abstract

A backlight module including a light box, a major source set, a light source set for adjusting color temperature and a diffusion plate is provided. The light box has at least one opening and the diffusion plate is disposed near the opening. Moreover, the major source set and the light source set for adjusting color temperature are disposed in the light box. The major source set provides a display light source with sufficient brightness, and the color temperature of the display light source can be adjusted by the light source set for adjusting color temperature. Therefore, improvements in the brightness and the color temperature of the display light source can be achieved at the same time by the backlight module.
