Current Landscape of Micro-LED Display Industrialization

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.
