The transparent substrate has a first groove, an inner wall of the first groove is a rough surface, and the first groove is provided with a quantum dot layer formed by curing a quantum dot paste. The transparent cover plate covers on a surface of the transparent substrate where the first groove is configured, a sealing adhesive layer is provided between the transparent cover plate and the transparent substrate, and the transparent cover plate is connected with the transparent substrate through the sealing adhesive layer and covered the first groove. In such a way, water vapor and oxygen are effectively isolated and the failure problem of the quantum dot layer is avoided, and the quantum dot layer is distributed uniformly in the first groove."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Quantum dot light guide module, manufacturing method, and backlight module","description":"A quantum dot light guide module includes a transparent substrate and a transparent cover plate.
