Color conversion structure, miniature LED structure and preparation method of color conversion structure and miniature LED structure

The invention discloses a color conversion structure, a miniature LED structure and a preparation method of the color conversion structure and the miniature LED structure. The preparation method comprises the following steps that a metal retaining wall is arranged in a reflection area on a first plate; the second plate is coated with an extinction material, and the coating height of the extinction material is larger than the height of the metal retaining wall; photoetching is carried out on the third plate, the removed area is a non-reflection area, and development is carried out after photoetching; and filling a non-reflection area on the fourth plate with a color array. Through the steps, a higher metal retaining wall can be formed, so that the color array is not easy to have a light crosstalk phenomenon. 本发明公开了一种颜色转换结构和微型LED结构及其制备方法，包括如下步骤：在第一板材上的反射区内设置金属挡墙；在所述第二板材上涂覆消光材料，消光材料的涂覆高度大于金属挡墙的高度；在所述第三板材上进行光刻，去除的区域为非反射区，经光刻后进行显影；在所述第四板材上的非反射区填充颜色阵列。通过上述步骤，能够形成较高的金属挡墙，使得颜色阵列不易于发生光线串扰的现象。
