Abstract
A brightness enforcement diffusion construction includes a transparent substrate made of plastic material e.g., PET, PMMA, MS, PS or PC, a diffusion layer disposed on one side of the light coupling or illuminating surface of the substrate, and brightness enforcement layer disposed on the other side; the diffusion layer contains multiple diffusion and/or acrylic particles to refract streams of light for producing diffusion results while enforcing the brightness of the streams of light that pass through the brightness enforcement layer.
Claims18
A brightness enforcement diffusion construction includes a transparent substrate made of plastic material and having both sides respectively a light coupling surface and an illuminating surface;
- a diffusion layer being disposed on the light coupling or the illuminating surface, and containing multiple diffusion and/or acrylic particles to refract streams of light for light diffusion;
- and a brightness enforcement layer disposed on the opposite side where the diffusion layer is provided.
A process for the manufacturing of the brightness enforcement diffusion construction is comprised of the following steps:
- Step A:
- a transparent substrate made of plastic material is provided that has a light-coupling surface and an illuminating surface respectively on both sides;
- Step B:
- a diffusion layer containing multiple diffusion and/or acrylic particles is disposed on either of the light-coupling or the illuminating surface of the transparent substrate;
- and
- Step C:
- a brightness enforcement layer is disposed on the opposite surface to that the diffusion layer is provided on the transparent substrate.
