Abstract
The present application discloses a manufacturing method for a display module and a display screen. The method includes: forming a semiconductor device by pre-processing a semiconductor epitaxial wafer; forming a first transparent layer on a substrate surface of the semiconductor device; forming a first opening exposing the substrate by etching the first transparent layer; forming a first quantum dot layer on the substrate surface exposed by the first opening and the surface of the first transparent layer; etching away the first quantum dot layer in the outer region of the first opening, and remaining the first quantum dot layer inside the first opening; and forming a DBR film layer that filters blue light.
