Multi-functional optical composite board having quantum dots of high uniformity

A multi-functional optical composite board having quantum dots of high uniformity, comprising a diffusion base layer, a first quantum dot-containing layer disposed on the lower surface of the diffusion base layer, and a second quantum dot-containing layer disposed on the upper surface of the diffusion base layer, wherein:

• the diffusion base layer comprises Generral Polystyrene (GPPS) basal body, and functional additive particles uniformly distributed and blended in the GPPS basal body;
• the first quantum dot-containing layer comprises a red quantum dot-containing layer and a green quantum dot-containing layer, wherein,
• the red quantum dot-containing layer comprises a first viscose substrate, and red quantum dot particles uniformly distributed and blended in the first viscose substrate;
• the green quantum dot-containing layer comprises a second viscose substrate, and green quantum dot particles uniformly distributed and blended in the second viscose substrate;
• the red quantum dot-containing layer is uniformly coated on the lower surface of the diffusion layer by a coating process;
• and
• the green quantum dot-containing layer is uniformly coated on the lower surface of the red quantum dot-containing layer by a coating process;
• the second quantum dot-containing layer comprises a third viscose substrate and a plurality of different quantum-dot particles uniformly distributed and blended in the third viscose substrate, the different quantum-dot particles are a mixture consisting of red quantum dot particles and green quantum dot particles, the second quantum dot-containing layer is deposited on the upper surface of the diffusion base layer by coating repeatedly.
