Samsung Display and LG Display have proven that their advanced display technologies are driving paradigm shifts not only in the display industry but also across XR, art, automobiles, and the AI era.

Samsung Display and LG Display, the two giants of the domestic display industry, showed off their technological competition to the max by unveiling a large number of next-generation OLED technologies at the 'K-Display 2025' exhibition held at COEX in Seoul for three days starting on August 7th. The two companies presented the future of displays in various fields such as XR, gaming, art, and automotive, focusing on their respective strategic technologies.


Samsung Display showcased its ultra-high-resolution XR display technology under the theme of 'Exploring Future Lifestyles with OLED Innovation!'

The 1.3-inch white OLEDoS (OLED on Silicon) boasts a resolution of 4,000 PPI, delivering a pixel density more than eight times that of smartphones. This maximizes the realism of XR through immersive content experiences.

RGB OLEDoS also exhibited a 1.4-inch product boasting an industry-leading resolution of 5,000 PPI and 20,000 nits of brightness.

The Micro LED Watch unveiled the world's first 6,000 nits bright Micro LED for smartwatches. It is implemented by transferring approximately 700,000 RGB LED chips, providing a flexible design and excellent viewing angle.

The QD-OLED Gaming Room showcased products optimized for various gaming scenarios, including 500Hz self-illuminating monitors, ultra-wide OLEDs, and foldable OLEDs.


The non-polarized OLED technology 'LEAD™' simultaneously improves brightness and power savings, and dramatically improves outdoor visibility.

The foldable OLED brand 'MONTFLEX™' emphasized its wrinkle-free screen and excellent durability, and proved its technological prowess through experimental displays such as tests in a freezer.


LG Display has organized an exhibition covering OLED technology from past to future under the theme of 'Shaping the Future.'

The most eye-catching space is the ‘OLED Heritage Zone.’

LG Display displayed a model of its technological development from the 15-inch prototype developed in 2009 to the 4th generation OLED panel.

△Tandem OLEDFrom the 2nd generation OLED with a two-layer structure, the 2nd generation with a deuterium atomic structure, the 3rd generation with micro lens array technology, and the 4th generation OLED with a primary RGB tandem structure, visitors were able to intuitively understand the evolution of OLED technology.

At the entrance to the exhibition booth, an 83-inch panel featuring 4th generation OLED technology was unveiled.

It is the first in the industry to have RGB primary colors stacked in independent layers, delivering a maximum brightness of 4,000 nits and providing an overwhelming sense of three-dimensionality and color reproducibility. The technological superiority was proven through a demonstration comparing image quality with the previous generation.

In the gaming field, LG Display also introduced the world's highest-spec OLED monitor panel.

The 27-inch QHD OLED, which has a refresh rate of 540Hz and can achieve up to 720Hz through DFR (Dynamic Frequency & Resolution) technology, boasts a DCI-P3 color reproducibility of 99.5% and a maximum brightness of 1,500 nits.

Additionally, the 45-inch 5K2K OLED panel achieves the world's highest resolution, and a space has also been created where visitors can experience the game firsthand.

Vehicle display technology also received attention.

The fully autonomous driving concept car featured a 57-inch pillar-to-pillar LCD, a 32.6-inch sliderable OLED, and a 29-inch outdoor LCD, suggesting a future mobility environment.

In particular, the 47.8-inch LTPS LCD with SPM (Switchable Privacy Mode) technology can block the passenger screen from the driver's seat, ensuring both safety and privacy.

Also innovative was the jog dial, which is the world's first stretchable display that can expand by up to 53%.


Low-power display technology targeting the AI era was also introduced. The 14-inch Tandem ATO simultaneously achieves high brightness and low power consumption, and is manufactured with a thin and lightweight single-glass substrate structure. The 14.5-inch LCD uses oxide TFT and low-power backlight technology to maximize battery life.


This exhibition showed that the competition for leadership in OLED technology has reached its peak, with Samsung Display focusing on ultra-high-resolution XR, wearable, and foldable technologies, and LG Display focusing on structural innovation in 4th-generation OLED and OLED for gaming and automotive applications.
