💡 Micro-LED, the next evolution beyond OLED, is finally entering the mass production era. What once cost $80,000 for an 89-inch dream display is now making its way into our daily lives through AR glasses and smartwatches. How are Japanese manufacturers positioning themselves in this technological revolution?
What is Micro-LED?
Micro-LED is a display technology that arranges ultra-fine LED elements smaller than 100 micrometers (about the thickness of a human hair) across a screen, with each element lighting up independently to create images. Red, green, and blue LEDs form one pixel as a set, and a 55-inch screen requires a staggering 6 million LED elements.
Like OLED, micro-LED is a "self-emissive" technology, but it uses inorganic materials instead of organic ones. This means no burn-in issues and a lifespan of approximately 100,000 hours. Furthermore, brightness can reach several to dozens of times that of OLED, enabling clear image display even outdoors.
Why Mass Production is Now Becoming Reality
Micro-LED has long been called the "ideal display technology," but high manufacturing costs have hindered its widespread adoption. Manufacturing a 4K display requires precisely placing approximately 24 million LED chips, and the traditional "Pick and Place" method was extremely time-consuming as chips had to be placed one by one.
The breakthrough came with advances in "mass transfer" technology. This technique enables the transfer of millions of elements at once, dramatically improving manufacturing time and costs. Canadian startup VueReal has developed a proprietary "cartridge method" that envisions direct mounting on automobile bodies by 2026.
Market research predicts the micro-LED market will grow from approximately $420 million in 2025 to $2.41 billion by 2030, representing an average annual growth rate of 41.8%.
AR Glasses: The First Battlefield
At SID Display Week 2025, held in May 2025, intense technological competition between micro-LED and OLED was on full display.
Particular attention was drawn to ultra-compact displays for AR (Augmented Reality) glasses. Micro-LED's greatest strength—its dramatically higher brightness—makes it ideal for AR glasses that need to function outdoors.
Taiwan's PlayNitride achieved an impressive pixel density of 5,644ppi in a 0.18-inch full-color display. The optical engine volume has shrunk to just 0.4cc, about 1/20th of conventional DLP systems, bringing AR glasses resembling regular eyewear within reach.
Full-scale adoption of micro-LED in the AR glasses market is predicted to begin in 2026, intensifying the battle for dominance with OLED.
Japanese Manufacturers' Strategies
Sony Semiconductor Solutions
Sony is known as a pioneer in the micro-LED field. In 2016, it was the first in the world to commercialize the "Crystal LED Display System" for professional use, which has been adopted in Hollywood for virtual background systems in film production.
At SID Display Week 2025 in May, Sony unveiled a 0.26-inch micro-LED display with an impressive 5,644ppi pixel density. Building on its established OLEDoS (OLED on Silicon) technology, Sony is now fully accelerating development in the micro-LED sector. Sony's strength lies in combining display technology with image sensing technology, aiming to deliver comprehensive value through real-time 3D sensing and polarization sensors.
Sharp
Sharp is developing monolithic micro-LED displays for AR headsets at its Fukuyama Semiconductor facility in Hiroshima Prefecture. The company achieved the world's first full-color display at 1,053ppi in a 0.38-inch size and has been working toward mass production.
Using proprietary "LSW" technology, Sharp prevents light leakage from quantum dot color conversion layers, achieving high-purity red and green colors. By adopting the monolithic method that allows simultaneous element bonding, the company aims to deliver highly reliable products.
Equipment and Materials Manufacturers' Contributions
Japan's strength extends beyond finished product manufacturers. Japanese companies are playing a leading role in manufacturing equipment essential for mass transfer technology.
TDK has developed a total solution including laser removal equipment, alignment machines, and mounting machines. Toray Engineering also offers a lineup from inspection equipment to bonding equipment and quantum dot coating equipment. Toray has successfully developed materials for laser transfer, and Shin-Etsu Chemical is advancing the development of transfer components, increasing the presence of Japanese companies throughout the supply chain.
Global Competition Landscape
Globally, development is accelerating among Korea's Samsung and LG Display, Taiwan's AU Optronics and Innolux, and China's BOE.
Apple has invested over $1 billion in the micro-LED field over the past decade, aiming to incorporate it into the Apple Watch Ultra. However, manufacturing cost issues reportedly delayed this to 2026 or later. Samsung is also planning to incorporate micro-LED into smartwatches, and the movements of both companies are expected to shape market formation.
At SID Display Week 2025, Taiwan's AUO unveiled a 42-inch micro-LED module, described as "the world's largest single-piece display." This demonstrated that manufacturing large displays as a single panel without tiling is becoming possible.
Micro-LED Possibilities and Challenges
Expected Applications
Micro-LED applications span a wide range.
Beyond AR glasses and VR headsets, smartwatches are expected to leverage high brightness and low power consumption for improved outdoor visibility. For automotive displays, attention is focused on HUDs (Head-Up Displays) that remain visible even in sunlight.
Micro-LED is also well-suited for transparent displays. Because emitting elements can be made smaller, light passes through more easily, enabling integration into shop windows and building glass.
Even more interesting is the integration of displays and sensors. Research is underway on utilizing micro-LED as an integrated platform that can "see, measure, and respond" by incorporating sensors and cameras between the microscopic elements.
Remaining Challenges
The biggest challenge remains cost. Currently available micro-LED products for home TV use cost around $80,000 (approximately 12 million yen) for an 89-inch model—far beyond the reach of ordinary consumers.
Additionally, manufacturing a single 4K display reportedly takes about 5 days, requiring improvements in production efficiency. Technological innovations continue toward mass production, including improving yield rates, further advances in transfer technology, and material cost reductions.
Japan's Challenges and Outlook
Following LCD and then OLED, Japan has the bitter experience of leading in R&D while falling behind Korean and Chinese competitors in the mass production race. Avoiding the same fate with micro-LED has become a crucial theme that will determine the future of Japan's display industry.
On the other hand, companies like Fujifilm, Japan Display Inc. (JDI), and Semiconductor Energy Laboratory (SEL) are developing a new approach—hybrid technology combining OLED and micro-LED. This has the potential to overcome the limitations of conventional FMM (Fine Metal Mask) and achieve ultra-high-definition displays at low cost, attracting attention as a unique Japanese technology.
Micro-LED is a technology that could fundamentally transform our "viewing" experience. Walking through the city with AR glasses, information overlays on the scenery before your eyes. Smartwatches remain crystal clear even in blazing sunlight. Your car's windshield becomes your navigation system.
That future is now within reach.
In Japan, technological development toward micro-LED mass production is accelerating. What discussions about display technology are happening in your country? If you have expectations for next-generation displays, please share your thoughts!
