Micro-LED display technology has emerged as a significant area of interest, with numerous research teams globally approaching it from various disciplines. Concurrently, several enterprises have initiated production or plan to invest in equipment manufacturing. However, the industry currently lacks standardized production processes for Micro-LED displays. This is largely due to major manufacturers adapting their equipment and material choices to suit their specific product applications. Nevertheless, advancements in recent years and developments within the supply chain reveal a gradual convergence of technology across the sector. This review paper aims to provide an investment and cost analysis perspective of the current industrial landscape of Micro-LED technology. It examines key aspects such as the selection of bonding materials, differences in driving modes, considerations for native RGB versus color conversion, strategies for cost optimization, market information and unique differentiation features of Micro-LED displays. To make this paper accessible to a broader audience, including those outside the electronics industry, key technical processes are described with clear explanations and the relevant context.
微发光二极管（Micro-LED）显示技术已成为一个备受关注的重要领域，全球众多研究团队从不同学科对其进行研究。与此同时，几家企业已开始生产或计划投资设备制造。然而，该行业目前缺乏微发光二极管显示器的标准化生产流程。这主要是因为主要制造商根据其特定产品应用来调整设备和材料的选择。尽管如此，近年来的进步以及供应链内的发展表明，该行业的技术正逐渐趋同。这篇综述文章旨在从投资和成本分析的角度审视微发光二极管技术当前的产业格局。它探讨了诸如键合材料的选择、驱动模式的差异、原生RGB与颜色转换的考量、成本优化策略、市场信息以及微发光二极管显示器的独特差异化特征等关键方面。为了让包括电子行业以外的更广泛受众能够理解本文，关键技术流程将通过清晰的解释和相关背景进行描述。
