Abstract
A quantum dot lens and a backlight module are provided. The quantum dot lens includes a lens body and a quantum-dot homogeneous-sol material. Wherein, the lens body has a light incident surface and a light exiting surface. The light exiting surface has a groove. The quantum-dot homogeneous-sol material is filled in the groove. Embodiments of the present application allow luminous efficacy and power efficiency to be improved.
