1. A method of manufacturing a high resolution micro-LED display panel, wherein the method comprises following steps:
providing a driving backplane and a light-emitting substrate, and bonding the driving backplane and the light-emitting substrate;
patterning the light-emitting substrate to form a pixel array;
forming a thin film packaging layer on an outside of the pixel array, the thin film packaging layer completely covering the pixel array;
forming quantum dots on the top of the thin film packaging layer to form a multi-color display;
forming a reflective array between two adjacent quantum dots to avoid optical crosstalk between the pixel arrays;
wherein a pixel definition layer is provided on a top surface of the thin film packaging layer, and the quantum dots are formed in said pixel definition layer.
