Micro LED optical interconnect targets AI racks amid unsettled standards
Surging demand for optical interconnects in AI computing centers is pushing Micro LED technology into short-reach optical transmission inside data center racks. Differing views on Micro LED's prospects in optical communications, recently expressed by Largan Precision Chairman En-Ping Lin and AUO Chairman Paul Peng, have sparked significant debate across the industry.
Sluggish end-market recovery, cautious procurement by brand customers, and persistently high upstream material costs are frustrating panel makers' efforts to implement price hikes for IT panels. In October, quotes for mainstream LCD monitor panels held flat, while notebook panel prices continued a slight downward drift due to weak demand and slow inventory digestion.
Once a global LCD manufacturing powerhouse, Taiwan's display industry has weathered financial crises, antitrust penalties and fierce competition from state-backed Chinese rivals. Now, after three decades of boom-and-bust cycles, its leading manufacturers are seeking a new future beyond screens, leveraging their expertise in precision manufacturing to enter automotive electronics, advanced semiconductor packaging and AI-related technologies.
AUO chairman Paul Peng said Micro LED remains a potential option for optical communications, despite Largan Technology's doubts about pairing it with multimode fiber in co-packaged optics. The comments underscore an unsettled market, where rising AI data-center bandwidth needs are driving competing approaches, while customers continue testing technologies before adoption.
AUO is expanding its push into AI-related businesses, including augmented reality (AR) glasses, low-Earth-orbit (LEO) satellite antennas, optical communications, and advanced semiconductor packaging. The display maker has secured board approval for NT$24 billion (US$739.92 million) in planned investment for 2026, as chairman and CEO Paul Peng positions the initiatives as a route to growth and supply-chain relevance.
LED packaging manufacturer Brightek Optoelectronic expects its automotive revenue share to exceed 60%, up from around 50%, following the opening of its Nantong plant and higher shipments. Its third-quarter 2026 gross margin is projected to recover to 30%, although tight mature-node logic IC supplies, constrained by foundries prioritising higher-margin memory products, have complicated its efforts to meet growing automotive orders.
E-paper giant E Ink Holdings has officially launched its next-generation color e-paper technology, E Ink Kaleido 4. Chinese e-reader brand Hanvon Technology is the first to adopt the display, integrating it into its second-generation M10C smart e-paper notebook, making it the world's first commercial device powered by Kaleido 4.
LCD TV panel prices face a tug-of-war in the fourth quarter of 2026 as panel makers push for increases while LCD TV brands maintain relatively steady purchasing and contract manufacturers remain cautious. Rising upstream material costs and continued production controls should help prices stabilize, but a broad-based increase remains unlikely.
Global TV market growth is under pressure, but premium models are poised to expand. As rising memory prices fuel "chip inflation" and squeeze margins on budget TVs, Samsung Electronics and LG Electronics are reshaping their product mixes, strengthening OLED and Micro RGB offerings to support pricing through picture quality and feature differentiation.
South Korea's LX Semicon is seeking buyers for more than 60 silicon carbide (SiC) power semiconductor patents, winding down a business it entered five years ago to reduce its reliance on display driver ICs (DDIs). The retreat comes as Taiwan's Novatek gains ground in the company's core display chip market, increasing pressure on LX Semicon to develop new revenue sources.
Competition in the global PC market is shifting from a focus on shipment volumes of low-cost models towards premium, high-performance devices, intensifying the race in OLED display technology. Tandem OLED, which combines higher brightness, longer lifespan, and lower power consumption, is emerging as a key technology for premium PCs, sharpening competition between South Korea's two leading panel makers, Samsung Display (SDC) and LG Display (LGD).

Huawei subsidiary HiSilicon is actively expanding its display chip footprint, with its display driver IC (DDIC) development once again capturing market attention. Kun Luo, CEO of HiSilicon Display, recently disclosed key milestones for its DDR-free display solution. Developed through co-optimization across chip architectures, panel designs, and algorithms, the solution increased panel effective light-transmission area by nearly 25%, enabling two collaborative products to reach million-unit shipments a year ahead of schedule.
