Latest Patents

One of Yang's latest patents is the "Quantum dot light diffuser plate and method for making the same." This 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, thus separating them 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, preventing water vapor and oxygen from penetrating the side end faces of the quantum dot layer. This innovation results in a diffuser plate that boasts a simple process, low cost, and high production yield.

Another notable patent is the "Diffusion plate for use in backlight module with low optical path distance." This invention discloses a diffusion plate designed for backlight modules with a low optical path distance (OD). It can be assembled on a backlight module with multiple light-emitting diodes (LEDs) as the light source below. Different diffusion particle additives are added to the surface layers and the main layer of the diffusion plate, which is then extruded using foaming extrusion technology. By varying the combinations of the refractive index and the amount of original resin materials, microbubbles, and diffusion particle additives, the light refractive index of the upper and lower surface layers is significantly greater than that of the main layer. This design allows for more effective diffusion of light emitted by the light source, achieving a better shading effect of MURA and producing a uniform surface light source.
