Manufacture method of red quantum dot-based high-color gamut white-light LED lamp bead

The invention belongs to the LED backlight processing field and relates to a manufacture method of a red quantum dot-based high-color gamut white-light LED lamp bead. According to the manufacture method of the invention, red quantum dot fluorescent powder is utilized, an organic solvent is adopted as a bridge, a mode according to which dissolution and extraction are performed sequentially is adopted encapsulate the red quantum dot fluorescent powder in a backlight LED lamp bead; and a blue light chip is adopted to carry out excitation, so that high-color gamut white light can be obtained. Through related technical means, the difficulty of encapsulation work is greatly reduced, and technological problems of little possibility of mixing the quantum dot fluorescent powder with encapsulation glue, high possibility of the failure of the agglomeration of the quantum dot fluorescent powder and little possibility of the solidification of the encapsulation glue due to the influence of organic matters can be solved.
