Abstract
The invention refers to a quantum dot light diffuser plate that can be assembled on a backlight module with blue LEDs as the bottom light source. Microstructures having concave portions and convex portions are formed on the surface of the diffuser plate. A quantum dot layer comprising green quantum dots and red quantum dots is applied only on the concave portions of the microstructures, and thus is separated by the convex portions into small parts independent of each other. A water-blocking and gas-blocking layer is arranged on the upper surface of the quantum dot layer. The water vapor and oxygen from the outside cannot penetrate the side end faces of the quantum dot layer and invade the entire quantum dot layer, such that, the diffuser plate of the invention can have the advantages of simple process, low cost and high production yield.
