Light source with quantum dots and manufacturing method and application of light source with quantum dots

The invention relates to the technical field of liquid crystal display, in particular to a structural improvement on a directly-down-type backlight source, and provides a light source with quantum dots. The light source comprises a substrate, a lamp bar and light mixing bodies arranged around the lamp bar are installed on the substrate, quantum dot stick blocks are arranged at the tops of the light mixing bodies, light emitted by the lamp bar is refracted by the quantum dot stick blocks to go out, and the light outgoing faces of the quantum dot stick blocks are curved surfaces. The invention further provides a manufacturing method of the quantum dot stick blocks and the novel directly-down-type backlight source assembled with the quantum dot stick blocks. According to the light source with the quantum dots, due to the fact that the light outgoing faces of the quantum dot stick blocks are the curved surfaces through the structural improvement on the quantum dot stick blocks, the light diffusion angle formed after the light emitted by the lamp bar passes through the quantum dot stick blocks is increased, and finally the light outgoing angle of the light source is increased.
