Abstract:
A backlight module includes a light guide plate and at least two groups of light sources. The light guide plate includes at least two independent light guide modules optically isolated from each other. Each group of light sources is located corresponding to an independent light guide module and controlled independently. A liquid crystal display using the backlight module is also related.
