The invention belongs to the technical field of lenses, and particularly relates to a novel HUD backlight module microstructure lens which comprises a shell, a lens and diaphragm integrated structure, a display screen and an LED lamp. Openings are formed in the two ends of the shell, the shell is hollow, and the lens diaphragm integrated structure comprises a first lens diaphragm structure and a second lens diaphragm structure; the display screen, the second lens diaphragm structure, the first lens diaphragm structure and the LED lamp are sequentially installed on the shell at intervals. The first lens diaphragm structure and the second lens diaphragm structure each comprise a diaphragm and a lens which are integrated through injection molding, the diaphragms are located at the bottoms of the lenses and face the LED lamps, and the curved surfaces of the lenses face the display screen. The novel HUD backlight module microstructure lens with the microstructure is synthesized by the lens and the diaphragm throug
