US Patent 8227979 - Quantum dot color matching

The color of quantum dots is determined by both the semiconductor material and the size of the quantum dots. This patent from Samsung teaches how to create customized LEDs with a color matching any physical material by properly selecting a population of quantum dots. Claim 1 reads:

1. A method comprising:

detecting a color of a material;

converting the color to an RGB/CMYK value; and

matching the color comprising:

mixing at least one population of a quantum dot into a matrix material; and

placing the mixture on a light emitting diode to convert a light output of the light emitting diode to a color matching the color of the material.
