Summary:The present disclosure discloses a method for manufacturing a color Micro LED display chip module, comprising preparing a Micro LED chip on a substrate, grinding and cutting the chip and then flip-bonding same on a driving basal plate, and peeling the substrate from the chip. Through fabricating a quantum dot hole site corresponding to a sub-pixel unit position of a chip on a transparent basal plate and filling a quantum dot light-color converter in the quantum dot hole site and depositing a quantum dot protective layer, a conversion device is fabricated independently on the transparent basal plate. Compared with processing a conversion layer on a substrate layer in the prior art, inverting a full-color quantum dot conversion device and then aligning and bonding same with the integrated monochrome Micro LED module base can improve the fabrication efficiency, eliminate the crosstalk between light and color in full-color Micro LED display.
