Abstract
The present invention provides a backlight module and a display apparatus. The display apparatus comprises the backlight module and a display panel. The backlight module comprises a light collector, optical fibers, a fiber light-outputting substrate, a light guide plate and fiber fixing collars. The optical fibers are connected between the light collector and the fiber light-outputting substrate. The light guide plate is disposed at one side of the fiber light-outputting substrate. The fiber fixing collars are attached to light-emitting ends of the optical fibers for fixing the optical fibers to the fiber light-outputting substrate. The present invention can use ambient light rays to form a backlight source.
