Claim:
1. A backlight module, comprising: a light guiding plate comprising at least one light incident surface; a light source unit being arranged close to the light incident surface; and a light conversion unit being fixed between the light source unit and the light incident surface, and the light conversion unit converts light beams emitted from the light source unit to white light beams; a reflective sheet arranged between a bottom surface of the light guiding plate and a back plate for reflecting light beams emitted from a bottom surface of the light guiding plate toward the light guiding plate to increase a light utilization rate; wherein the light conversion unit is a complex fluorescent material bar of quantum dots comprising a plurality of fluorescent quantum dots, and light beams emitted from activated fluorescent quantum dots are composited with light beams emitted from the light conversion unit to generate white light beams; and wherein the complex fluorescent material bar of quantum dots comprises a plurality of fixing legs, wherein two of the fixing legs are respectively arranged on a top surface and a bottom surface of the complex fluorescent material bar, and other fixing legs are symmetrically arranged on the top surface and the bottom surface the fixing legs configured on the top surface and the bottom surface of the complex fluorescent are fixedly connected with a substrate of the light source unit to fix the complex fluorescent material bar of the quantum dots such that the complex fluorescent material bar of quantum dots is fixed between the light source unit and the light incident surface, and the substrate is parallel to the light incident surface of the light guiding plate.
