Color conversion method of mine-LED

The invention belongs to the technical field of semiconductors, and discloses a mine-LED color conversion method which comprises a substrate, a retaining wall, an LED light-emitting wafer, white ink and quantum dot ink, and the color conversion method comprises the following specific operation steps: S1, firstly, the retaining wall is manufactured around the LED light-emitting wafer in a manner that the white ink is printed and cured at the same time, and the height of the retaining wall needs to be higher than that of the LED light-emitting wafer so as to prevent the ink from overflowing; and S2, curing and printing a layer of white ink on the LED light-emitting wafer while printing, so as to obtain uniform light color. The two kinds of ink are used for printing respectively, white ink does not need to be added into the quantum dot ink, the printing precision of the quantum dot ink is improved, and the yield of products is improved; and the white ink is independently printed, so that the printing stability i
