Abstract

The invention discloses a backlight module, an optical enhancement unit and a manufacturing method of the optical enhancement unit. The backlight module has a light guide part, a light source, a reflection part, a grating, a prism sheet, a diffusion film, an optical gain material and a reflection layer, and the light guide part The light incident surface is located on the side between the bottom surface and the light exit surface; the light source is arranged on one side of the light entrance surface; the reflection part is arranged along the bottom surface of the light guide part; the grating is arranged along the light exit surface of the light guide part, with multiple etc. The bright area and the dark area arranged at intervals; the surface of the prism sheet adjacent to the grating has a plurality of microstructures, and the first side and the second side of the horizontal section of the microstructure form an angle; the diffusion film has a concave part to make the light gain material It is accommodated in the concave part and the reflective layer is formed on the flat part of the diffusion film.

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...
