The invention discloses a preparation method of a color conversion structure and novel black glue. The preparation method comprises the following steps: preparing a filling template; preparing a filling box dam; coating a matting material; and stripping the filling template: stripping the filling template on the first plate to obtain a second plate. According to the technical scheme, the filling template and the filling box dam are manufactured firstly, then the filling template and the filling box dam are coated with the extinction material, and the extinction material can be cured in the filling template and the filling box dam, so that the extinction material with lower viscosity can also form a thick film, and the problem of optical crosstalk is prevented. Meanwhile, the novel black adhesive is obtained by mixing the BM black adhesive and the transparent photoresist, the viscosity of the novel black adhesive formed after mixing is high, and a thick film can be formed to serve as an extinction material in
