The AI wave is rapidly reshaping the global semiconductor supply chain, and that upheaval is opening a new growth chapter for Taiwan’s LED industry. As Taiwan’s LED makers move away from the price wars of the consumer market, Nvidia’s push to upgrade AI transmission standards to 1.6T, 3.2T, and beyond is exposing the physical limits of copper wiring, making scale-up the first battlefield in the competition between photons and electrons. Micro LED’s high bandwidth and heat resistance position it as a key technology for the 3.2T-plus optical communications era.
