Micro-display chip structure and preparing method therefor

A preparing method for a micro-display chip structure, comprising:

• forming a plurality of light-emitting units on a side of a driving circuit substrate, the plurality of light-emitting units at least comprising first light-emitting units, and the first light-emitting units being configured to emit light of a first color under driving of the driving circuit substrate;
• forming a supporting frame on the driving circuit substrate, the supporting frame comprising a plurality of supporting units, each supporting unit of the plurality of supporting units being disposed corresponding to each light-emitting unit of the plurality of light-emitting units, and the supporting unit at least covering a sidewall of the light-emitting unit;
• forming a first reflective layer on a sidewall of the supporting unit;
• and
• forming a color conversion layer above the plurality of light-emitting units, the color conversion layer at least comprising first wavelength conversion units, the first wavelength conversion units being disposed corresponding to the first light-emitting units, and the first wavelength conversion units being configured to convert the light of the first color emitted by the first light-emitting units into light of a second color.
