Industry Transformation through Micro LED Technology

TSMC has announced a strategic partnership with U.S. startup Avicena to jointly produce Micro LED-based optical interconnect products. The collaboration aims to replace traditional electrical connections with advanced optical communication technologies, addressing the increasing demands for data transmission from graphics processing units (GPUs). This development marks a notable trend as Micro LED technology expands beyond traditional displays and into optical communication sectors.

The Micro LED technology’s characteristics—small size, high modulation rate, and seamless integration with silicon-based CMOS processes—allow for the creation of high-density arrays capable of parallel optical communication. This offers significant benefits over copper wiring, such as higher bandwidth density and improved energy efficiency, presenting new opportunities for the development of advanced AI hardware architectures.

Avicena’s innovative LightBundle™ technology utilizes GaN Micro LED arrays and is designed for integration with high-performance CMOS integrated circuits. The advantages of LightBundle™ include low power consumption, minimal latency, extensive coverage, and high bandwidth density, making it a suitable solution for applications in high-performance computing (HPC), artificial intelligence (AI), machine learning (ML), 5G wireless systems, and aerospace.

The company secured $25 million in funding in 2022, followed by $65 million in 2025, with investors like Samsung, Micron, and SK Hynix. Another startup, Hyperlume, raised $12.5 million for its Micro LED optical interconnect technology earlier this year, indicating a growing interest in this niche market. Avicena has also partnered with companies like LumiLeds and ams OSRAM to enhance Micro LED array production and focus on mass manufacturing capabilities.

Additionally, the LED industry is becoming increasingly aware of the potential for Micro LED in non-display fields, with players like Ennostar committing to developing core technologies for AI-driven optical communication applications.

In this context, Taiwanese manufacturers are strategically positioning themselves to lead in Micro LED technology. TSMC’s involvement in Micro LED innovation, rumored connections with Apple for AR devices, and focused R&D efforts from manufacturers like AUO and Innolux reflect an ambition to capitalize on their semiconductor strengths. While South Korean firms like Samsung and LGD have firm footholds in OLED technology, Taiwanese companies are navigating the competitive landscape by shifting focus to next-generation display technologies through Micro LED.

This calculated scope of work emphasizes Taiwanese manufacturers’ intent to innovate and set high barriers to entry in the global technology scene, ensuring they maintain influence amidst changing market dynamics.
