Abstract

The invention discloses a backlight module, an optical reinforcement unit and a manufacturing method of the optical reinforcement unit. The backlight module comprises a light conducting part, a light source, a reflection part, an optical grating, a prismatic lens, a diffusion film, a light gain material and a reflection layer. A light entering face of the light conducting part is arranged on a side edge between the base face and a light outgoing face. The light source is arranged on one side of the light entering face. The reflection part is arranged along the base face of the light conducting part. The optical grating is arranged along the light outgoing face of the light conducting part, and comprises multiple bright regions and dark regions which are arranged at an equal interval. The surface, adjacent to the optical grating, of the prismatic lens comprises multiple micro-structures. A first angle is formed between a first side face and a second side face of the horizontal section of each micro-structure. The diffusion film comprises a recessed part so as to allow the optical gain material to be accommodated in the recessed part and allow the reflection layer to be formed on a flat part of the diffusion part.

Description

technical field [0001] The invention relates to an optical enhancement unit, in particular to a backlight module with quantum dots. Background technique [0002] With the continuous development of display technology, liquid crystal display devices (Liquid Crystal Display, LCD) are the mainstream of flat panel display technology in terms of mass production scale and product application popularity. In the liquid crystal display device, the backlight module that provides the backlight required by the liquid crystal display device plays a very important role. [0003] Generally speaking, the backlight module of the liquid crystal display device is provided with an LED light-bar (LED light-bar) composed of a plurality of light emitting diodes to provide the backlight required by the liquid crystal display device. Since the panel module of the liquid crystal display device does not have the ability to emit light, the function of the backlight module is to supply sufficient bright...
