A New Era Driven by AI and High-Speed Data Transmission
In recent years, the rapid rise of generative artificial intelligence (Generative AI) and cloud computing has fundamentally reshaped the semiconductor and information technology landscape. Large language models and AI accelerators require data centers to move enormous amounts of model weights and training data in extremely short periods of time. As a result, bandwidth requirements have rapidly expanded from 400 Gb/s to 800 Gb/s, 1.6 Tb/s, and even 3.2 Tb/s.
Traditional copper interconnects are increasingly becoming a bottleneck due to limitations in latency, signal attenuation, and power consumption. According to Taiwan industry report, a co-packaged optics (CPO) architecture integrating micro-LED light sources can reduce the power consumption of a 1.6 Tb/s module from about 30 W to roughly 1.6 W, representing only about 5% of the energy consumption of copper interconnects.
As a result, a new wave of high-speed optical interconnect technologies, centered on CPO, silicon photonics, and micro-LEDs, is widely viewed as a key enabler of next-generation data centers.
For Taiwan, the traditional flat-panel display industry faces mounting pressure from the rise of mainland China’s supply chain and declining profit margins. Transformation has become urgent. This article examines how Taiwanese panel makers are expanding into advanced packaging via FOPLP, satellite communications, and micro-LED optical interconnect technologies. It explores how Innolux and AUO are moving beyond pure display manufacturing to enter fields such as satellite antennas and optical communications, while also comparing the opportunities and challenges of silicon photonics and micro-LED-based CPO technologies in the AI era.
Challenges and Transformation Drivers for Taiwan’s Panel Industry
LCD Market Saturation and Declining Profit Margins
Taiwan’s display industry experienced a golden era during the 2000s and early 2010s. However, rapid capacity expansion by Chinese panel manufacturers and the gradual saturation of the LCD television market have intensified price competition, significantly compressing average profit margins.
To find new growth engines, Taiwanese panel makers have increasingly invested in higher-value segments, including:
AMOLED displays
Automotive displays
Medical displays
Transparent display technologies
At the same time, technology integration with semiconductor manufacturing and advanced packaging has emerged as another promising pathway.
Technology Transformation: FOPLP, Micro-LED, and Satellite Communications
From a manufacturing perspective, LCD panel processes share several similarities with semiconductor fabrication, including glass substrates, driver circuitry integration, and packaging technologies. Taiwanese panel manufacturers possess deep expertise in large-area glass processing, fine metal interconnects, and high-precision patterning. These capabilities allow them to enter fields such as large-panel advanced packaging and micro-LED manufacturing.
For example, Innolux is leveraging its Generation-3.5 glass production line (620 × 750 mm) to develop Fan-Out Panel-Level Packaging (FOPLP) technology. The substrate area is approximately seven times larger than a conventional 300 mm glass wafer, enabling significantly higher I/O pad density while also reducing power consumption.
Meanwhile, AUO is extending its long-accumulated micro-LED expertise into optical communications and co-packaged optics architectures, placing micro-LED light sources on glass substrates to enable high-speed optical interconnects.
In addition, panel manufacturers are leveraging thin-film display and liquid-crystal technologies to develop flat-panel satellite antennas, expanding their reach into satellite communications and automotive V2X connectivity markets.
