AUO Unveils 127-Inch Micro-LED TV at Touch Taiwan 2025 – Signaling Ambitions in the Premium Display Market

/in /by

AUO, a Taiwanese global display specialist, captured the attention of the industry by showcasing a 127-inch Micro-LED TV with its latest technology at Touch Taiwan 2025 in April. More than just a technology demonstration, AUO’s exhibit is seen as a strategic move with the company’s full-scale commercialization in the ultra-large premium TV market in mind.

The 127-inch Micro-LED TV on display was based on AUO’s proprietary bonding technology and pixel structure design, and realized 4K resolution and high brightness of over 1,000 nits on average. It demonstrated excellent picture quality performance, including color reproduction (DCI-P3 100%), which is an advantage of Micro-LED TVs.

AUO’s 127-inch Micro-LED TV on display is aimed at commercial digital signage, as well as high-end home cinema and special purpose markets. Considering the commercialization potential of Micro-LED technology and the spread of demand, AUO will continue to expand its product lineup with various sizes and specifications.

Micro-LED is a next-generation spontaneous light display technology that miniaturizes LED devices into individual pixels, offering longer lifetimes, higher brightness, freedom from burn-in, and superior response speeds compared to OLEDs. However, the technology is still technically complex and expensive, so AUO’s prototype display can be considered a symbolic milestone. It will be interesting to see how AUO’s Micro-LED technology will make an impact in the global premium TV market and whether it will be commercialized and achieved high production yields in the future.

Here are some of the key implications of the 127” Micro-LED TV development

  • World’s largest single 42” Micro-LED module in the world
  • Improved competitiveness by simplifying the entire product design/manufacturing process
  • Reduces the color difference between tiled modules
  • 5th generation Mass-Transfer technology reduces process costs and accelerates product commercialization

More details and technical analysis will be presented in a forthcoming Micro-LED report from UBI Research.

RGB Mini-LED TVs are forming a confrontation composition with OLED TVs, and future trends will be closely watched.

While Micro-LED TVs are expected to enter the consumer market in 2025, RGB Mini-LED TVs with lower OLED performance are expected to enter the market and compete with OLED TVs. Chinese panel producers, which lag far behind Korea in OLED production volume, are strategically focusing on RGB Mini-LED technology development, while Samsung Electronics and SONY are also entering this field.

Hisense introduced a 116″ 4K TriChroma RGB Mini-LED TV at CES2025, featuring 97% BT.2020 color reproduction, 10,000 nits peak brightness, and a 10K-class local dimming zone. TCL also plans to launch an RGB Mini- LED TVs in 2026.

Samsung Electronics plans to launch RGB Mini-LED TVs, including Mini-LED and Micro-LED under the brand name RGB Micro-LED TV, in various sizes during 2025, and quietly unveiled a 98-inch 8K product at CES 2025.

Sony has also revealed that it is developing a general RGB LED Backlight technology, which is expected to be introduced into the Bravia XR Mini-LED TV and released as the Bravia XR RGB Mini-LED TV.

The price of the RGB Mini-LED Backlight is expected to be similar to the price of the traditional Mini-LED Backlight, and it will be interesting to see how it will fare against OLED TVs in the future.

Micro LED TV, is the price competitive compared to OLED TV?

/in , /by

“It needs to consider how to resolve the price competitiveness compared to other displays, such as OLED, before Micro LED is to be applied to the big screen TVs of 60 inches and 70 inches in future.”

Moon Dae-Gyu, professor of Soonchunhyang University, mentioned as above while explaining the micro LED technology at the ‘latest OLED technology trends seminar’ organized by UBI Research in Seoul COEX on April 26th, 2018.

“Micro LED is attracting attention as a technology capable of realizing a high resolution display of 1,000 ppi or more. Since micro LEDs are individually obtained from a LED wafer by the photo process, they are not affected by the size and shape of a substrate, and have the merits that the advantages of existing LED such as luminance, lifetime and low power consumption, can be applied as they are.” professor Moon added.

In addition, it is expected to be a good environment to show the advantages of micro LED in the field where power consumption is very important, such as wearable appliances. He also predicted that it is possible to implement display in no tile form in very large display area such as public display and digital wall, which might be easy segments for micro LED to enter.

However, regarding the mass production of micro LED TV, which is becoming a recent issue, Moon said, “In order to implement 4K, 24.8 million LED chips (with a size of 10 μm/chip) are required. At the 4 inch wafer, which is currently being commercialized, 4K panels can be produced twice only. Thus, it is doubtful whether micro LED is competitive compared to LCD and OLED in terms of mass production.”

Commenting about TFT uniformity and pixel uniformity of the micro LED, he mentioned “TFT uniformity can be sufficiently compensated by the compensation circuit that is currently applied to OLED, but it should be considered how to solve the color imbalance problem.”

Micro LED TV, which was introduced by Samsung Electronics in CES 2018, and received a lot of attentions at the time, but it was disagreed about commercialization. In particular, Kang In-Byung, CTO of LG Display, pointed out, “About 25 million LEDs are needed to realize 4K micro LED TV. Even if 1 LED is 1 Korean Won, the cost might be 25 million. And when the circuits and boards are added, it would be a huge price.”
