Compiled Report — According to foreign media reports on July 15, South Korea’s Ministry of Trade, Industry and Energy announced that it will invest 484 billion KRW (approximately USD 350 million, or RMB 2.51 billion) by 2032 to develop iLED (Inorganic Light-Emitting Diode) display technologies, including Micro LED, QD LED, and Nano LED.
The South Korean government stated that while the country currently maintains a leading position in the OLED market, it still lags behind other nations in the iLED sector. Critical components such as LED epitaxy, chips, and materials remain highly dependent on imports. The purpose of this investment is to foster a fully localized industrial ecosystem and cultivate new growth drivers for South Korea’s display industry.
OLED Competition Intensifies + Supply Chain Security Concerns: South Korea Bets on iLED
According to industry reports, South Korea once dominated the global OLED market almost entirely through its two giants, Samsung and LG. However, in recent years, Chinese companies such as BOE, TCL CSOT, Visionox, HKC, and Tianma—backed by strong government support—have rapidly risen. They have not only surpassed South Korea in the LCD panel sector but are also accelerating in OLED, closing in on Korean manufacturers at a remarkable pace.
Specifically, South Korea still holds an advantage in the high-end flexible OLED segment, but Chinese manufacturers are quickly gaining market share in the mid-to-low-end OLED segment, while the technological gap continues to narrow. In advanced technologies such as FMM-free OLED, Chinese players are also catching up. For example, Visionox’s ViP (Visionox Intelligent Pixelization) mass production process was fully validated across production lines in 2023 and will be introduced to new G8.6 generation AMOLED lines. Meanwhile, TCL CSOT’s inkjet-printed OLED technology is expanding from professional applications into the consumer market, with a clear target on the high-potential mid-size display segment.
In addition, iLED technology is considered the next-generation display technology that could disrupt OLED. Compared with OLED, iLED—thanks to its use of inorganic materials—offers superior performance in lifespan, brightness, image quality, and energy efficiency. It also avoids common OLED issues such as screen burn-in (image retention) and brightness limitations. These advantages make iLED especially attractive for automotive displays, mobile devices, and wearable electronics.
It is also worth noting that iLED technologies, particularly Micro LED, have an industrial chain logic that is fundamentally different from OLED. The core lies in the manufacturing, inspection, and transfer of micron-scale LED chips, aligning the industry more closely with the semiconductor sector. China, with its robust LED industry foundation, complete ecosystem, and strong policy support, has already listed Micro LED as a strategic development priority. Multiple Chinese enterprises have invested heavily in R&D and achieved breakthrough progress, posing a formidable challenge to Korean manufacturers.
Although Korean companies entered Micro LED and QD LED development earlier, their production capacity constraints and high dependence on imported key components and materials leave them vulnerable to supply chain security risks.
The Ministry of Trade, Industry and Energy (MOTIE) of South Korea also directly pointed out in its statement that the iLED chips and materials currently required by South Korea are highly dependent on imports. This means that if the market shifts to iLED in the future, South Korea may not only be unable to continue its past success with OLED, but could even find itself in a passive position in future competition due to the lack of core technologies and upstream supply chains.
In order to seize the initiative in this global race that will determine the display industry landscape for the next decade, South Korea had already set its sights precisely on the complete ecosystem of iLED display applications as early as May 2022, launching a national-level dedicated investment program in the role of both a pursuer and a supply chain gap-filler.
Against this backdrop, Seoul Semiconductor has in recent years continued to explore the growth potential of Micro LED and related technologies. Its Micro LED products, based on WICOP (Wafer-Level Integrated Chip on PCB, a package-free technology), have already entered mass production and are being used in commercial display scenarios such as outdoor advertising and virtual studios.
Now, MOTIE has officially announced the launch of a large-scale national R&D project for iLED, with clearly defined goals that directly target key challenges. As the South Korean government acknowledged, this investment aims to resolve three major issues: first, to reverse South Korea’s relatively lagging position in iLED technology; second, to reduce the country’s severe dependence on foreign-made key LED chips and core materials by building an autonomous and controllable domestic supply chain; and third, to identify a new economic growth engine for the nation beyond OLED.
Conclusion
In summary, the South Korean government’s investment in the development of iLED is, on the one hand, aimed at addressing its own shortcomings in next-generation technologies for key industries and securing supply chain safety to prevent being overtaken by competitors. On the other hand, it hopes to break through technological bottlenecks ahead of others, replicate the success of OLED in the blue ocean market of LED, and continue to lead the development of the global display industry.
From the perspective of the global display industry, this technology will influence the evolutionary path of display technologies worldwide. In any case, the global competition surrounding iLED has already been fully launched, and future developments across regions will continue to attract close attention.
