Example Embodiment
[0038] Example 1
[0039] The backlight module provided by this embodiment includes a blue light source, a light guide plate, and a reflective layer. The light guide plate has a light incident surface, a first light exit surface, three light leakage surfaces, and a second light exit surface parallel to the first light exit surface. The light incident surface of the light plate is correspondingly arranged, and the reflective layer is arranged correspondingly to the second light exit surface of the light guide plate. The backlight module further includes a light conversion layer arranged on a light leakage surface. The light conversion layer includes a light conversion material. The material is CdSe / ZnS core-shell quantum dots, the base material of the light conversion layer is polyacrylate, the particle size of the quantum dots is 10nm, the weight percentage of the quantum dots in the light conversion layer is 8%, and the thickness of the light conversion layer is 200μ0. And the t...
