Abstract: An epitaxial layer in a first color and a first-color light-emitting unit of a preset shape are prepared on a substrate layer; a patterned photomask is deposited on a side, away from the epitaxial layer in the first color, of the substrate layer, and is etched to form color conversion layer location holes; because light-emitting units and the location holes are formed based on the preset shape, designed color units are separated, and mixed-color light is filtered out, and light interference is prevented; color conversion fluorescent materials are not sprayed into part of the color conversion layer location holes and color conversion fluorescent materials in the other two colors of three primary colors except the first color are sprayed into the other color conversion layer location holes.

Abstract: Disclosed are an integrated Micro LED chip and a fabrication therefor. An epitaxial layer in a first color and a first-color light-emitting unit of a preset shape are prepared on a substrate layer; a patterned photomask is deposited on a side, away from the epitaxial layer in the first color, of the substrate layer, and is etched to form color conversion layer location holes; because light-emitting units and the location holes are formed based on the preset shape, designed color units are separated, and mixed-color light is filtered out, and light interference is prevented; color conversion fluorescent materials are not sprayed into part of the color conversion layer location holes and color conversion fluorescent materials in the other two colors of three primary colors except the first color are sprayed into the other color conversion layer location holes, such that the full-color integrated Micro LED chip is obtained easily.
