The present application provides a full-color Micro-LED and its preparation method and display device. The full-color Micro-LED preparation method bonds a hollow metal layer on a monochrome Micro-LED array and sets quantum dots in the hollow metal layer. This method only uses a monochrome Micro-LED array and has a high yield rate. By using a hollow metal layer as the structural layer of the quantum dots, the metal layer is easy to hollow out. The metal acts as a separation wall between the quantum dots. On the one hand, it can prevent light crosstalk between the quantum dots. On the other hand, the metal plays a role in reflecting light, so that the light emitted by the quantum dots will not be scattered, the quantum dots emit more light, and the utilization rate of blue light is improved. This preparation method can reduce the steps and processes of flipping the quantum dots to the monochrome Micro-LED array by first bonding the hollow metal layer to the monochrome Micro-LED array and then setting the quantum dots in the hollow metal layer, making it easier to manufacture.

The waterproof sealing performance and reliability of the polymer waterproof coiled material with the self-adhesive layer at a building pipeline part can be effectively guaranteed, and the adaptability is wider.

This invention belongs to the field of methanol-to-hydrogen technology, specifically a methanol partial oxidation hydrogen production device, including a water storage section and a reaction section partially located within the water storage section. The reaction section includes a vapor inlet at one end and a reaction gas outlet at the other end, located inside and outside the water storage section. A reaction area is provided between the vapor inlet and the reaction gas outlet, located inside the water storage section. It is understood that this invention uses a horizontal annular reaction tube, effectively utilizing the width of the water storage section, resulting in a compact structure and stable placement. Multiple independent reaction chambers are built into the tube, each corresponding to a single oxygen source pipe and catalyst, improving reaction uniformity, ensuring consistent catalyst utilization and lifespan, and facilitating unified maintenance. Simultaneously, through the coordination of several inlet straight pipes, outlet straight pipes, and oxygen supply pipes, uniform vapor diffusion, centralized recovery of reaction gas, and uniform oxygen supply are achieved, ensuring the consistency of reactions in each reaction chamber. This parallel structure provides better reaction performance and higher efficiency compared to the traditional series method.
