[Objective] To investigate and analyze the current status, needs and issues of information system construction in blood collection and supply institutions in Beijing, and to provide strategic suggestions for the further improvements. [Methods] The qualitative information of information systems from relevant departments of Beijing Red Cross Blood Center, central blood stations, blood banks and hospitals in Beijing were collected by sequential interview method, and analyzed. [Results] There were 6 information systems in operation in blood collection and supply institutions in Beijing, covering functions such as blood collection and supply service management, blood donation information inquiry and reporting, blood collection and supply institution business management, blood donor information management, blood information promotion and information disclosure. However, there were still issues such as low level of system informatization, lack of top-level design for information construction, non-unified data standards, and incomplete system analysis and statistical functions. [Conclusion] Blood collection and supply institutions in Beijing need to further carry out network infrastructure construction, reconstruct system architecture, improve the functions of the blood management information platform, unify data and interfaces to achieve information sharing, and use emerging technologies to achieve intelligence and precision in blood collection and supply services and management.

As a new generation of display technology, micro-LED demonstrates the advantages of high brightness, low energy consumption, long life, and self-luminous. However, the technical bottlenecks, such as difficulties in achieving highefficiency full-color displays, have hindered their industrialization processes and popularity. The full-color display is a crucial technology for the commercialization of micro-LED. However, with the high degree of integration and miniaturization of LED chips, the mass transfer of RGB chips to the same substrate for achieving full-color display has resulted in high costs and low yields. Therefore, there is an urgent need to discover a simpler and more efficient method for full-color display. This paper provides an overview of micro-LED micro-display device fabrication technologies and several methods for achieving full-color displays, focusing on the quantum dots color conversion layer method, the RGB direct alignment method, the special structure method, and the optical lens method. The technical challenges and development trends of micro-LED micro-displays are also discussed. [ABSTRACT FROM AUTHOR]
