South Korea's OLED share rebounds to 68.7% in 2025
South Korea's global OLED market share increased by 1.5pp to 68.7% in 2025, marking its first rise in a decade and drawing widespread attention. According to Chosun Biz, the Korea Display Industry Association (KDIA) cited Omdia data showing South Korean companies regained ground in the OLED sector after years of decline.
Samsung Electronics has replaced the head of its Visual Display (VD) business in a rare mid-cycle reshuffle, responding to weakening demand and intensifying global competition in the television market.
PlayNitride's sharp first-quarter loss and strategic Singapore expansion carry implications for international Micro LED supply chains and partnerships, signaling industry consolidation as the company relies on customer ramps, China deployments, and new collaborations in optical communications to drive recovery and future growth across wearables, automotive, and AR markets through 2027 and beyond.
Siliconware Precision Industries Co., Ltd. (SPIL), a subsidiary of ASE Technology Holding, acquired two Nanke-area plants in 2026 from HannStar Display and its affiliate HannsTouch Technology as part of a broader push to expand advanced packaging capacity for artificial intelligence workloads.

Taiwan backlight module maker Coretronic swung to a first-quarter loss and warned of continued pressure in the second quarter, with currency swings, geopolitical risks, raw material costs, and soft demand clouding visibility. A recovery is expected only in the second half, when peak season demand returns.

Coretronic has reported its first quarterly loss since the 2008 global financial crisis, even as revenue reached a multi-year high, underscoring margin pressure and shifting product dynamics across its business.

Optical communication technology is shifting from traditional pluggable optics toward co-packaged optics (CPO) architectures. Advanced packaging technologies are extending from wafer-level to panel-level, bringing fan-out panel-level packaging (FOPLP) into the spotlight. At the intersection of these trends, Taiwan's panel manufacturers are actively entering the semiconductor packaging field in search of new growth momentum.
Radiant Opto-Electronics will wait two to three years before accelerating investment in optical communications and co-packaged optics (CPO), as uncertainties around industry structure and business models persist, chairman Justin Wang said.

LG Display reported its strongest first-quarter operating profit in half a decade and signaled an end to years of workforce restructuring, as it continues to shift toward high-end OLED panels.

Adoption of OLED by Apple is becoming inevitable, with Radiant Opto-Electronics Corp. (ROEC) chairman Justin Wang expecting the most visible impact to emerge by 2027.

As global companies race to capture opportunities in AI optical communications and co-packaged optics (CPO), Taiwanese LED and optoelectronics firms are actively transforming and entering the field. Everlight Electronics, a leading LED packaging company, has also begun low-profile positioning, considering investments in related startups and leveraging its strengths in high-end optocouplers to play a key role in optical signal transmission and coupling.
Japan Display Inc. (JDI) is accelerating its withdrawal from the low-temperature polycrystalline silicon panel market by selling its Tottori plant to Yahata Toei Real Estate, a deal expected to close by September 30, 2026. The Tottori factory stopped production in March 2025, following the closure of the Mobara plant in November 2025.
