Micro-display chip structure

The utility model provides a micro-display chip structure, and solves the technical problem that in the color conversion technology of a Micro-LED display in the prior art, due to the fact that a quantum dot film layer is limited by the thin thickness and the influence of a film layer structure, absorption is incomplete, and the color purity is poor. According to the micro-display chip structure provided by the utility model, the first transmission and reflection layer can further filter the first color light possibly doped in the second color light, so that the light emitting purity of the sub-pixel region is improved, and the color gamut of the whole display screen is improved; meanwhile, the first transmission and reflection layer reflects the first color light doped in the second color light into the first wavelength conversion unit, so that the first color light which is not converted by the first wavelength conversion unit is absorbed and converted by the first wavelength conversion unit again; and the
