Abstract
A backlight module, a display device and a method for driving the same are disclosed, such that brightness of display device can be increased when rendering 3D display. The backlight module includes a light guide plate, a light-splitting structure and an edge light source, wherein the light-splitting structure includes a plurality of strip-shaped first light-splitting units and a plurality of strip-shaped second light-splitting units, the first light-splitting unit and second light-splitting unit are alternately disposed on the light output surface of the light guide plate, each of first light-splitting unit and second light-splitting unit comprises at least one grating strip, the first light-splitting unit is configured for directing light to output towards a first position external to the backlight module, and the second light-splitting unit is configured for directing light to emit towards a second position external to the backlight module. The backlight module is applied into the display device, such that the display device achieves 3D display function.
