Samsung, LG tighten grip on high-end OLED market with iPhone 17 supply
South Korea's top display makers Samsung Display and LG Display are cementing their dominance in the high-end OLED market by becoming the only firms to supply Apple's upcoming iPhone 17 lineup with next-generation low-power panels known as low-temperature polycrystalline oxide OLEDs.
According to industry sources Friday, Apple is set to adopt LTPO panels across the new iPhone 17 series, a move that further sidelines Chinese competitors like BOE, which continues to struggle with mass production due to low yields and technological hurdles.
LTPO OLEDs, known for reducing power consumption by 15 to 20 percent compared to traditional low-temperature polycrystalline silicon or LTPS OLEDs, have become the gold standard for premium smartphones.
Originally developed by Apple in 2014, the technology gained traction only in recent years due to complex manufacturing and high costs. It is now widely used in top-tier models like Samsung's Galaxy Ultra and Apple's iPhone Pro.
Samsung and LG's exclusive supply to Apple — the world's largest smartphone maker — highlights their technological edge over Chinese rivals in the lucrative high-end display sector.
In the first quarter of this year, the two Korean firms controlled a combined 71.8 percent of the LTPO OLED market, according to Omdia. In contrast, Chinese players, including BOE, TCL CSOT and Visionox, collectively held just 27.8 percent.
'BOE is far from catching up,' said an industry official on condition of anonymity. 'The technical and yield barriers for LTPO remain high, and Korean firms have already built a commanding lead.'
Samsung and LG are also ahead in intellectual property. As of 2022, LG held 649 LTPO OLED-related patents and Samsung 376 — significantly outpacing BOE (373), TCL (106) and Tianma (99), across jurisdictions including the US, China and Korea.
Looking ahead, Apple is expected to adopt LTPO3, the next-generation iteration of the technology, as early as 2027.
Korean firms are already ramping up R&D in anticipation, aiming to widen the performance gap with Chinese competitors.
Beyond LTPO, both Samsung and LG are spearheading innovation in other next-generation display formats. Samsung recently unveiled an electroluminescent quantum dot display with an industry-high 4,000-nit peak brightness, while LG introduced its fourth-generation OLED technology, setting a new benchmark in brightness performance.
Both companies are also accelerating development in emerging fields such as OLED on silicon for XR and VR devices, as well as rollable and flexible displays, the markets where Chinese manufacturers have yet to gain meaningful traction.

Too close to Seoul to stand out? Gyeonggi bets on independent travelers to revive tourism
Gyeonggi Province, which surrounds Seoul and is home to over 13 million people, is rolling out a new strategy in hopes of attracting more international tourists. Despite being one of South Korea's most accessible regions from the capital, trouble navigating often keeps foreign visitors away. In an attempt to address the situation, the province announced its '3.3.5.5 Strategy." Despite its size, access to the DMZ, and proximity to Incheon Airport, Gyeonggi Province's share of foreign visitors dropped from 14.9 percent in 2019 to around 10 percent in 2024, according to data from South Korea's Ministry of Culture, Sports and Tourism. Seoul's share has long held at around 80 percent. Meanwhile, the country's tourism landscape has changed. Over 80.5 percent of foreign tourists in 2024 were Free Independent Travelers — those who plan trips on their own rather than booking through a group tour. In 2019, FITs made up 77.1 percent. Gyeonggi now wants to target this growing segment. The strategy sets four measurable goals: Boost international visitor share from 10 to 30 percent. Increase average stays from 2.13 days to 3 days. Raise spending per tourist from 350,000 won to 500,000 won (about $215 to $360). Improve the repeat visitation rate from 34 to 50 percent. Why Gyeonggi gets overlooked The paradox is that Gyeonggi is geographically convenient, but functionally inaccessible. Booking regional buses and trains often requires Korean-language apps or domestic credit cards. Car rentals are available, but GPS systems and maps are primarily designed for local users. Google Maps still lacks turn-by-turn navigation in Korea. Korean apps like Naver Map and Kakao Map support English, Chinese and Japanese, but often fall short for tourists unfamiliar with Korean signage or cultural context. These barriers help explain why South Korea, despite ranking No. 14 overall in the World Economic Forum's 2023 Travel and Tourism Development Index, landed at No. 60 in tourism services and infrastructure. What the province plans to fix To address this, Gyeonggi Provinceworked with national tourism agencies, universities, and research institutes to develop a four-part action plan. It includes: Improved transportation: more shuttle buses, FIT-friendly day tours, a new tourist taxi system, and a dedicated Gyeonggi tourism center in Seoul. Better digital tools: smarter booking platforms and information services for foreign users. Expanded experiences: DMZ tours, regional food programs, and new outdoor and industrial tourism offerings. Targeted marketing: a global tourism brand and campaigns focused on younger travelers. Officials say implementation will begin in 2026, starting with high-impact projects. The province also plans to work with Seoul and Incheon to create a regional tourism network and is pushing the national government to ease lodging and transportation regulations. 'Our goal is to make Gyeonggi Province a place where international visitors can explore freely and comfortably,' said Jang Hyang-jeong, the province's tourism policy director. 'We want them to discover that Korea is more than just Seoul.'

Hyundai's US tariff headache, explained in 2 minutes
The new 15 percent tariff deal between South Korea and the US is forcing Hyundai Motor Group to fundamentally rethink its strategy in its second-largest market. With the loss of its zero-tariff edge under the South Korea-US free trade agreement, the Korean auto giant is now grappling with tough choices — from adjusting vehicle prices to relocating production of key models from Korea to the US. Tariff impacts New 15% US tariff on Korean car exports replaces previously threatened 25% duty. Hyundai Motor and Kia export 1.5 million vehicles to the US annually — about 25% of total global sales. Estimated 3-4% hit to overall profit margin, prompting strategic overhaul. No room for big price hikes Raising prices by over 3% would be needed to offset losses. But Hyundai risks losing competitiveness if it increases prices more than rivals like Toyota, which has already raised prices by $200–$270. Hyundai's pricing strategy likely to focus on regional customization, option flexibility, including removal of some standard features. Production shift on the table Hyundai is in talks with labor unions to shift production of high-demand models — especially hybrids and SUVs — from Korea to the US. All Hyundai Motor and Kia hybrid models are currently made in Korea despite surging US demand. Labor union hurdle A 1999 labor agreement requires union approval for any overseas production shift. Experts say this will need to be renegotiated due to what's described as a 'life-or-death threat' to Hyundai's export-driven business model. What's at stake Hyundai sold 28,733 hybrid vehicles in the US in July, up 38% year-on-year. Shifting hybrid production could help avoid tariffs and protect market share, but labor resistance could delay plans.

Seoul shares close nearly flat with mixed sector performance
South Korean stocks finished nearly unchanged Wednesday as gains in tourism and retail shares offset losses in semiconductors and pharmaceuticals. The local currency slipped against the US dollar. The benchmark Korea Composite Stock Price Index climbed 0.14 point, or 0 percent, to close at 3,198.14. Trade volume was a little slim at 319.8 million shares worth 10.7 trillion won ($7.7 billion), with winners outnumbering losers 644 to 236. Foreigners and institutions sold a net 67.5 billion won and 53.7 billion won worth of local shares, respectively, while retail investors purchased a net 46.9 billion won. Tourism and retail shares led the daily gain following the government's decision to start a visa waiver program with Chinese group tourists from next month. Hotel Shilla jumped 4.79 percent to 49,250 won, and Shinsegae increased 3.27 percent to 176,900 won. Major cosmetics firm AmorePacific rose 1.26 percent to 128,800 won, and Kolmar Korea gained 2.79 percent to 99,400 won. Energy shares were also among the winners, as Doosan Enerbility mounted 2.31 percent to 66,300 won and the state-run Korea Electric Power Corp. vaulted 7.44 percent to 41,150 won. However, chip and drug stocks went south as Trump said again he would announce new tariffs on those imports soon. Chip giant Samsung Electronics fell 1.57 percent to 68,800 won, and its rival SK hynix retreated 1.9 percent to 258,500 won. SK Biopharmaceuticals tumbled 8.89 percent to 101,500 won, and Samsung Biologics dropped 1.9 percent to 1,031,000 won. The local currency was quoted at 1,389.5 won against the greenback at 3:30 p.m., down 1.2 won from the previous session. (Yonhap)
